Antifreeze poisoning containing propylene glycol

Symptoms of antipyretic poisoning containing propylene glycol may not appear immediately after ingestion because it takes time for the body to metabolize chemicals. The body converts antifreeze chemicals into smaller alcohols and acids such as glycolaldehyde, glycolic acid, glyoxylate, and oxalic acid. The onset and severity of symptoms can vary depending on the type and amount of antifreeze a person eats. In general, antifreeze poisoning occurs in three stages. We discuss each of the following:

first stage

The first stage of antifreeze poisoning usually begins between 30 minutes and 12 hours after ingestion. Ethylene glycol and propylene glycol in antifreeze first affect the central nervous system. The early signs of antifreeze poisoning may be similar to those of alcohol poisoning. Symptoms include dizziness, fatigue, headache, seizures, nausea and vomiting, and coma.

second stage

People generally enter the second stage of antifreeze poisoning. During this stage, the body continues to metabolize the chemicals in antifreeze to toxic acids. These acids lower the pH level of the blood, which leads to a condition called metabolic acidosis. At this stage, antifreeze poisoning affects several organs including the kidneys, brain, lungs and liver. People in the second stage of antifreeze poisoning may experience irregular heartbeat, shallow breathing, confusion, and changes in blood pressure.The person may also become unconscious or comatose at this stage. A doctor may suggest more aggressive treatments for an individual in the second stage of antifreeze poisoning.

The third stage of antifreeze poisoning contains propylene glycol

The third stage of antifreeze poisoning occurs between 24-72 dimensions. If left untreated, the accumulation of calcium oxalate crystals can lead to kidney failure. A doctor may recommend hemodialysis to treat antifreeze poisoning. Early diagnosis and treatment of antifreeze poisoning is essential to reduce the risk of permanent organ damage and long-term health effects. The treatment of antifreeze poisoning focuses on the following: Prevent the continuation of antifreeze metabolism in the body Eliminate antifreeze and toxic metabolites from a person’s bloodstream Provide supportive care, especially in more severe cases that include organ failure. Doctors prescribe antidotes such as fompizol and ethanol to prevent the metabolism of antifreeze chemicals to toxic metabolites in the body. Antidote therapy can help prevent further kidney damage but does not eliminate metabolites that have already accumulated in the kidneys. A doctor may then focus on restoring a person’s blood pH to a normal level, such as using a bicarbonate solution through a vein. Your doctor may also recommend hemodialysis to remove antifreeze and toxic metabolites from the bloodstream. During hemodialysis, a health care professional inserts a tube with a needle into a person’s arm. This tube is connected to the dialysis machine. The person’s blood flows along the tube into the device, which filters out toxins and waste products. The filtered blood is then transferred to another person’s arm through another tube.

Who is most at risk for propylene glycol antifreeze poisoning?

Workers in industries that produce or use antifreeze containing propylene glycol are at the highest risk of poisoning. Especially those who are involved in car maintenance and aircraft defrosting. Although skin contact is the main route of exposure to propylene glycol, vapors or fogs can be inhaled when the chemical is heated, stirred, or sprayed.

Tips for preventing antifreeze poisoning containing propylene glycol

• Do not pour antifreeze into water bottles or other containers. Keep the chemical in your original container.
• If you spill antifreeze while working on your car, clean the leak area and wash the area with water, as the pet may accidentally eat it.
• Always place the lid on antifreeze containers. Keep chemicals out of the reach of children and pets.
• As a precaution, do not drink anything you do not know.

Propylene glycol in resin

Propylene glycol is used in the manufacture of high performance unsaturated polyester.Unsaturated esters are synthesized in the laboratory by the concentration of saturated and unsaturated anhydrides with glycols. The resulting condensate is mixed with styrene monomer to form the unsaturated polyester resin formula. When propylene glycol is mixed with 30% ethylene glycol or 20% diethylene glycol, a better balance of tensile strength, tensile modulus, elongation at break, tensile strength, impact resistance, surface hardness, abrasion resistance and water absorption It is obtained by baking resin.

Unsaturated polyesters

Unsaturated polyesters are the third class of heat molding resins. They are produced with a density of one diol with a combination of saturated and unsaturated anhydrides.Condensing products (reactive resins) react highly with vinyl monomers, such as styrene, to form highly durable structures and coatings.The properties of the bonded resin depend on the types of anhydrides and glycols used and their relative amounts. Most commercial unsaturated polyester (UPR) resins are made from phthalic and maleic anhydride as unsaturated and unsaturated components, and propylene glycol as the diol in the polymer.Unsaturated polyester resins mainly in the production of fiber-reinforced plastics and plastic products full of hygienic materials, tanks, pipes, nets and high performance components for the marine and transportation industries such as closing panels and hulls, fenders , The hull of the boat is used. Unsaturated polyester resins are also used in coatings and adhesives.

Propylene glycol in alkyd resins

Alkyd resins were first synthesized in the 1920s and, due to their excellent performance, continue to compete endlessly with growing synthetic-based polymer resins. Due to its high compatibility with many polymers and a large number of formulations, alkyds are superior to other systems in many applications with special demand. Adaptability, along with their biodegradability and possibly recyclability, makes alkyds extremely environmentally and economically attractive. Propylene glycol is used in the synthesis of alkyd resins.

Global market for propylene glycol and resin

Increased use of unsaturated polyester resin in various applications of reinforced plastics is predicted for the growth of the fuel market. Bio-based propylene glycol is widely used as a cooling and antifreeze due to its low freezing point and high viscosity, thus increasing its importance in the automotive and general industries. Increased automobile production and sales in developed as well as developing countries are expected to increase demand for bio-based propylene glycol over the next six years. It is predicted that the increase in demand for non-ionic surfactants and the increase in demand for adhesives, emulsifiers and lubricants based on propylene glycol will lead to market growth. The global market for bipropylene glycol is divided into five regions: Asia Pacific, Europe, Latin America, North America, the Middle East, and Africa. Asia-Pacific is expected to grow at the highest CAGR rate due to the large number of producers of polyunsaturated resins and polyester fibers, as well as increasing demand from the construction sector. Demand for Bio-based propylene glycol is expected to increase in developing countries such as China, Japan, India and Vietnam due to the growth of the commercial and organizational construction sector.

Propylene glycol in paints and varnishes

Color is everywhere. People paint walls, floors, furniture, fences, products and more, and for a designer, paint is a vital tool for protecting surfaces. The construction and chemistry of paints have undergone fundamental changes since the 1940s. Today, paints and varnishes are complex mixtures of different components. The exact composition of a paint or varnish is designed to meet the specific needs of its use as well as the expectations of health and safety requirements. In the mid-1980s, Dan-Edwards replaced ethylene glycol (a toxic solvent widely used in latex paints) with propylene glycol, which has a similar function. Unlike ethylene glycol, propylene glycol is non-toxic and on the FDA list for use in foods, beverages, cosmetics and pharmaceuticals. Most paint manufacturers still use ethylene glycol. Propylene glycol is also widely used in the production of water emulsion paints (also called latex) for the interior coating of buildings, especially for the production of semi-gloss paints. Propylene glycol improves the properties of paints by having its properties completely dissolved in water, because its low evaporation increases the time intervals of using the brush for use in paints. Paints include solvents, resins, pigments, extenders and additives. A solvent is a liquid that carries solid components of paint and evaporates after use, leaving a dry, solid layer on the surface. Latex paints may be thought to use water as a solvent, but propylene glycol and an excipient also play a role. Each of these materials has its own purpose and is created in different ways. Propylene glycol is used as an antifreeze to help retain wet parts, which has the ability to help evaporate all the water before the latex particles in a continuous layer. Propylene glycol and water play an important role as part of the solvent, but the merger is just as important. After applying the dye and evaporating the water and glycol solvent, the blender causes the latex resin grains to flow together and eventually evaporate like the rest of the solvent. The raw materials in latex paint solvents include water, ethylene or propylene glycols and blenders, as well as all the chemicals used to make glycols and auxiliaries.Is the presence of propylene glycol in paints dangerous for children? Propylene glycol ethers, which are commonly found in cleansers and paints, may be a concern for toddlers. Chemical compounds emitted from paints and common household cleaners may increase the risk of asthma and allergies in children.

Propylene glycol

Propylene glycol has a lower level of toxicity and is considered a food grade antifreeze. This type of glycol is safer to control than ethylene and can be easily disposed of. Propylene glycol is commonly used in the food industry or in industrial refrigeration systems where people may come into contact with liquid. Propylene glycol can also be more viscous than ethylene, even if used at very low temperatures and has little effect on heat exchange rates. It is important to note that you should never mix different types or brands of glycols together, as this will cause the product to shrink and clog the filters in the refrigeration system. Potentially cause problems with heat transfer and fluid flow Applications of monopropylene glycol.

Propylene glycol in chillers and air conditioners

Propylene glycol in chillers and air conditioners must be mixed with water for proper functioning. The type and amount of water used are key factors that must be considered. Each glycol chiller has its own set of manufacturer recommendations for the best type of water to use in that system. Although municipal tap water may be acceptable at first, it is almost never recommended that non-ionized water be stored for long periods of time. Because it can adversely affect certain metals in the chiller. Calculating the proper ratio of glycol to water in your cooling system depends on the coldest temperature that the glycol solution reaches during operation. If an indoor cooling system is used where there is no opportunity for freezing, the amount of glycol required is significantly less than the requirement of a glycol chiller used outdoors and the temperature is subject to freezing. Also, if a program needs to work at very low temperatures, it should use a glycol mixture similar to the outdoor system. In a cooling system, this temperature is typically the saturated suction temperature in the evaporator, and typically 10 degrees Fahrenheit below the set temperature of the chiller. It is important to use the right ratio of glycol and water in the cooling system.

Application of propylene glycol in chillers and air conditioning industries

Propylene glycol antifreezes are high performance and inhibit heat transfer fluid. They are low in toxicity, making them an ideal choice for use in industrial, commercial or agricultural food processing applications.

Propylene glycol is commonly used in food processing facilities or other areas where contaminated drinking water or food may be contaminated.

Antifreeze propylene glycol chiller is essential in any cooling system that is exposed to ambient temperatures below 7 ° C. Having glycol inside the chiller, air blast cooler or adiabatic cooler system protects your equipment from damage.

Low freezing points of glycol mixtures make them ideal for cooling devices below the freezing point of water. Therefore, glycol and water mixtures are often used to cool freezers and similar environments.

The low temperatures associated with glycol mixtures make them useful for applications where a chiller must transfer large amounts of heat quickly. Heat is a by-product of many chemical reactions.

The ability of glycol to transfer heat quickly makes it useful for maintaining the temperature of chemical reactions. For this reason, mixtures of propylene glycol and water are often used to cool fermentations in breweries. It is very important that you regularly monitor the glycol level in your chiller system to ensure maximum efficiency and level of protection. Maintaining a glycol chiller level is part of a chiller maintenance prevention program.

How is glycol distributed?

Propylene glycol is stored and transported in stainless steel or mild steel tanks and can be transported by tank trucks. This material is not classified as dangerous for any type of transport and is not dangerous to health. Its flash point is 103 degrees Celsius and its specific gravity is 1.04.

Propylene glycol in wet wipes

One of the most common causes is moisturizing. Wipes are used on the skin. Of course, after cleansing, it keeps the skin moist for a short time. Propylene glycol is similar to glycerin at this time. It can absorb some water from the air to the skin to prevent dry skin due to evaporation of liquids after wiping the wipes. Another reason is the addition of antibacterial propylene glycol. Wipes are disposable but most wipes are not packaged in one piece. After the package is torn, unused wipes come into contact with air. If left unchecked, airborne bacteria can easily settle to the ground and, if reused, could endanger human health. The antibacterial activity of propylene glycol can delay the spread of bacteria on wet wipes, thus protecting the safety of users. This is especially important when wet wipes are used as baby and feminine health products.

Is propylene glycol dangerous in wet wipes?

It is a moisturizing agent and although it is not toxic, it is a stimulant and penetration enhancer. This means that it helps other substances to penetrate deeper into the skin, which is not always ideal. If it is in contact with the body for a long time, it can be associated with skin irritation, eye and lung irritation. In fact, the toxicity and stimulation of propylene glycol are very low. Its toxicity is mainly reflected in the effect on the nervous system, and this condition occurs only if a very high dose is taken. Propylene glycol is generally very irritating to the skin and mucous membranes. Many water-based human lubricants on the market use propylene glycol and glycerin as key additives to achieve moisturizing and thickening effects. In order to achieve a sticky and slippery touch, the content of propylene glycol will be higher than a wet wipe. These lubricating products, which are used in the most sensitive parts of the mucous membrane of the human body, do not cause irritation or discomfort Applications of monopropylene glycol.

Why not worry about wiping your hands with a wet towel?

Exposure to propylene glycol in daily life generally does not pose a health risk, but there are cases of poisoning due to accidental ingestion by infants and young children. For example, a two-year-old child had symptoms of poisoning from chewing on a clean wipe. Therefore, parents should take good care of their children to prevent unnecessary injuries. In short, it is unlikely that the amount of propylene glycol in a baby wipes is not high enough to cause poisoning.

Benefits of propylene glycol for the skin

1. Absorbs water

Propylene glycol acts as a moisturizer at low concentration levels. It carries water to the outer layer of the skin. Therefore, cosmetics that contain propylene glycol are useful for hydrating the skin and removing dry skin and your matte appearance.

2. Moisturizing element

When propylene glycol acts as a moisturizer, it also offers some moisturizing benefits to your skin. Your skin will feel smooth after using products enriched with propylene glycol.

3. Reduces the symptoms of aging

We all grow old after a certain period of life. Our skin has a component called natural moisturizer that dries with age. It causes signs of aging such as wrinkles, scaling and roughness. Propylene glycol can slow down the aging of your skin.

4. Increases the effect of cosmetics

Apart from having unique benefits, propylene glycol also helps to absorb other active ingredients in cosmetics. This substance simplifies and strengthens the penetration of substances through the skin. Naturally, cosmetics work more efficiently and have the best effect.

5. Prevents water wastage

Propylene glycol acts as an emollient to create a protective layer on your skin. This prevents water loss and leads to smooth and healthy skin.

6. It is useful for acne

One of the most common and annoying skin problems we face is acne. Many cosmetics do more damage to acne than just cleansing. But propylene glycol is safe for acne because it has no fat and helps the skin to heal over time and the acne to disappear.

Industrial grade propylene glycol (PGI)

Industrial grade propylene glycol is a colorless, odorless and slightly viscous liquid. Unsaturated polyester resins, coolant and antifreeze, hydraulic and brake fluid, heat transfer fluids, paints and coatings are used in applications. The purity and good quality of our products make you buy propylene glycol exclusively from our company.

Highly refined propylene

Ultra-refined propylene glycol is a very pure propylene glycol that is used as a solvent, stabilizer, water-soluble solvent, plasticizer, moisturizer, antiseptic and antimicrobial preservative. Standard propylene glycol tends to oxidize easily to form propionaldehyde, lactic acid, pyruvic acid, and acetic aldehyde. Super Refining minimizes impurities that accelerate the oxidation of propylene glycol without changing its chemical structure, reducing the additive-API interaction and subsequent degradation. The highly refined propylene glycol is designed to provide the highest level of purity of propylene glycol in formulations containing active ingredients in cases where maximum purity of excipients is required.

Biopropylene glycol

Biopropylene glycol is an alternative to petrochemicals for the production of propylene glycol from glycerin. Contrary to popular belief, this technology does not rely on oil. The raw material of biopropylene glycol is glycerin, a drug grade that is hydrogenated in the liquid phase with a copper catalyst. To maintain the reaction, two serial fixed bed reactors are used, which occur at a temperature of 175 to 195 ° C and a pressure of 75 to 200 bar. The crude product is then sent to a two-column distillation unit for refining. It produces pharmaceutical grade propylene glycol (1,2-propandiol, monopropylene glycol). Differences between propylene glycol and glycerin Propylene glycol and glycerin are two products that are often confused with each other. These two alcohol combinations look almost identical at first glance, which can make it difficult for those unfamiliar with them to understand the products they want to buy. Both are used in a variety of products from the chemical, food, cosmetics and pharmaceutical industries. Glycerin is a non-toxic liquid made from natural vegetable oils. It can also be synthesized by processing propylene. Chemically, the alcoholic compound is made up of three OH groups. It is a clear, colorless liquid, sweet and syrupy taste. Glycerin is commonly used as a moisturizer (meaning to retain moisture), a solvent and a preservative. Glycerin is also emollient, which means that it has a soothing and soft skin quality, which is very popular for making soap. Propylene glycol is a synthetic liquid derived from propylene oxide. Chemically, it consists of two groups -OH. Like glycerin, it is a clear, colorless, sweet-tasting chemical. It is also commonly used as a moisturizer, solvent and preservative. Due to its toxicity to glycerin, the amount of propylene glycol in a product is usually small. According to the FDA, this substance is recognized as a generally safe chemical for human use. Glycerin and propylene glycol are used for many similar products. There are several factors to consider when deciding which product is best for you. Glycerin is a natural product that makes the price slightly higher than synthetic propylene glycol. Propylene glycol and glycerin have different consistency. Glycerin is much thicker and usually tastes sweeter. Propylene glycol and glycerin are important and diverse components in making the products we use in our daily lives. Global consumption of propylene glycols grows by an average of 2.0-2.5% per year during the years 24-2019. Above-average growth rates are seen in areas such as mainland China, the Indian subcontinent and Southeast Asia, where high demand for unsaturated polyester resins, cosmetics and personal care products is expected during the forecast period.

Side effects of propylene glycol

Skin irritation and allergic reactions

Propylene glycol is literally used as a skin moisturizer and emollient in thousands of personal care products. It can be very useful to deal with dryness and improve the overall texture of the skin. Although generally considered safe, it is not suitable for everyone. Cosmetic grade propylene glycol is considered safe and possibly non-toxic by large organizations such as the Environmental Working Group. Therefore, for most people, its presence in lotions is usually not a concern. But it can irritate the skin of some people and cause an allergic reaction, especially if they have sensitive skin from the beginning. If you notice redness, irritation or itching after using a product containing propylene glycol, stop using it and contact your dermatologist. You may have a skin allergy to this substance. If you buy a product containing propylene glycol, test it on a small area of ​​your skin before use. If redness, irritation or itching does not occur in the test area after 24 hours, you are safe with this substance. A common adverse reaction to propylene glycol involves mild skin irritation, including redness. This usually happens in people who are allergic to the chemical and it subsides shortly after the body has had a chance to break down the compound. In contact with the eyes and face, propylene glycol can also be irritating and cause mild conjunctivitis.

Potentially toxic to kidneys and liver

Propylene glycol is used in many IV medicines, including lorazepam, a drug that reduces anxiety and seizures. It is often prescribed to patients with extensive burns as a sedative during the healing process or to the mentally ill. When lorazepam is prescribed for a long time in high doses, doctors have seen possible kidney problems in the form of increased creatinine levels in the blood. In general, creatinine (a product of muscle breakdown and growth) flows at a constant level in the blood. Excess creatinine is a sign that the kidneys are not able to process compounds at a normal rate. People who currently have poor kidney function are unlikely to be able to process propylene glycol efficiently and should avoid exposure if possible. On the plus side, propylene glycol may actually be able to protect your liver from damage from the common headache drug acetaminophen.

Not safe for babies or pregnant women

Be careful when using this substance during and after pregnancy to ensure the health of your children. Babies cannot break down the substance as quickly as adults. This is because of the enzyme pathways that are still developing at birth. The growth period can last from six months to four years. Before these enzyme pathways can fully develop, parents should avoid eating or exposing themselves to many potentially harmful chemicals for their children, and pregnant mothers should do the same.

glycol Nervous symptoms

When taken orally, it is present in a number of people with varying degrees of nervousness, including seizures and other severe psychological symptoms. Of course, these people may be allergic to this substance. When propylene glycol is used instead of ethylene glycol in antifreeze products, it is considered a “non-toxic antifreeze.” Many people because of the presence of this substance in antifreeze (a substance used for air conditioning) And they are very worried about using it in their food, which has caused a lot of excitement in recent years. Many people fear the connection between antifreeze and food, although propylene glycol simply lowers the freezing point of water (just like salt) and only enters antifreeze products to replace hazardous chemicals. According to the Environment Working Group, the set of research on this material is considered “fair”. It ranks propylene glycol “3” on its Health Concern Scale, meaning that the risk it poses is relatively low. This substance is not bioaccumulation. This means that at normal doses or exposure to propylene glycol, in people with healthy kidney and liver function, it breaks down in the body within 48 hours and does not accumulate over time, causing toxicity in the body. The Food and Drug Administration (FDA) has identified propylene glycol as “generally safe” from a toxicological point of view. A comprehensive report by the Centers for Disease Control and Prevention on the effects and potential toxicity of propylene glycol found no major health concerns.

Cosmetic use

Solvent for cosmetics, binder, emollient, moisturizer. In perfume is a solution and additive, perfume and cologne.

In food

Used as coloring, emulsifier, solvent for antioxidant, moisturizer, solvent for cooling (refrigeration / freezing) in food. Propylene glycol (PG) is a relatively non-toxic liquid and is actually a colorless, odorless and tasteless substance. PG is used in various applications due to its high solubility in a wide range of materials. SKC is producing various types of PG and meets customer requirements with precise quality control and production management. Monopropylene glycol (MPG) and dipropylene glycol (DPG) are derivatives of propylene oxide. PG and DPG are traditionally used as moisturizers, as a carrier and of course as a solvent.

In the case of propylene glycols

MPG and DPG are produced in a two-step process. The first stage is the reaction of propylene oxide with water to a mixture of MPG and DPG and the second stage is distillation and Sale of original Korean propylene glycol purification of the mixture into two separate components Everything we need to know about propylene glycol.

MPG

MPG is the largest volume of propylene glycol. It is a colorless, viscous, odorless liquid. It is highly moisturizing and miscible in all ratios with water, alcohols, esters, ketones and amines. It has limited mixing with halogenated hydrocarbons and cannot be mixed with aliphatic hydrocarbons. The most important end use of MPG is in the production of unsaturated polyester resins, which in turn are used to make everyday items such as bathtubs, small boats, and tanks and chemical water pipes. Other end uses include paints and coatings, aircraft antifreeze / defrost, industrial antifreeze and coolants, detergents, hydraulic fluids and cosmetics.

DPG

DPG is also a colorless, moisturizing liquid that can be mixed with water in any ratio and is highly soluble in most organic solvents. DPG end applications include unsaturated polyester resins, fabric softeners, alkyd resins, cosmetics and polyurethane.

Environmental fate of propylene glycol

In the soil

Factors affecting the fate and behavior of propylene glycol in the terrestrial environment are pH, organic matter, clay content, cation exchange capacity, aeration and texture. The major processes that determine the mobility and distribution of propylene glycol in the terrestrial environment are divided into surface and groundwater due to their high solubility in water as well as rapid degradation and biodegradation. Soil evaporation and uptake are fateful processes of only minor importance. Propylene glycol has an almost half-life in soil due to its biological decomposition equal to or less in water (from 1 to 5 days). However, the rate of degradation will vary according to soil characteristics, temperature and other environmental conditions.

propylene in the water

Propylene glycol is highly soluble in water and is easily metabolized by higher microbes and organisms. The biodegradation process requires oxygen. Therefore, the concentration of dissolved oxygen (DO) in the receiving water may be negatively affected after the high release of propylene glycol. Corrosion inhibitors may also have adverse effects on biodegradable microorganisms, thus slowing down the degradation process.

in the air

Due to its high solubility and low vapor pressure, propylene glycol is not expected to evaporate easily from air to water. If released into the atmosphere at high temperatures, propylene glycol must be present almost completely in the vapor phase and undergo rapid photochemical oxidation. The half-life of this reaction is estimated at 20 to 32 hours. Contact the sales team of PersianUtab to buy the original Korean propylene glycol.

Monopropylene glycol has many functions and is used in many skin care products due to its various applications.

Here are the benefits of monopropylene glycol for the skin

Absorbs water

At low concentrations, propylene glycol acts as a moisturizer, meaning it binds water and hydrates the outer layer of the skin. When used in cosmetics, it gives the skin a moist and dewy appearance. As a moisturizer, it also has moisturizing benefits and smoothes the skin with a light, non-sticky feel. Eliminates the visible signs of aging Moisturizing properties also make it a useful substance for dry or old skin. With age, the skin loses part of it called the natural moisturizing agent (NMF) and subsequently dries out, which adds to the skin’s wrinkles, causing flaking and roughness. Monopropylene glycol helps to bind water from the environment. Restores skin moisture and delays aging.

Increases penetration

Helps to penetrate the active ingredients of cosmetics through the skin, which in turn are effective.

Prevents water loss

As an emollient, propylene glycol creates a protective layer on the skin that prevents water loss and helps to smooth and soften the skin.

Safe for acne prone skin

Because it is not greasy, it is also ideal for people with acne.

Toxicity and safety of propylene glycol

Monopropylene glycol can have toxic effects when ingested in excessive amounts. The most prominent risk is the central nervous system, which can lead to decreased heart rate and slow breathing. Exposure to high levels of monopropylene glycol indicates destructive effects on red blood cells. Other cases of toxic exposure include seizures, coma, and kidney failure. The populations most at risk are children. Monopropylene glycol poisoning is unlikely to occur under normal circumstances. The most likely cause of such poisoning is the overuse of injectable drugs containing monopropylene glycol. Does not irritate the skin, but slightly irritates the eyes.

The shock effects of America’s polar storm in February continue to reverberate around the world. Many chemical refineries across the Gulf region were affected by prolonged power and raw material outages, while snow and ice disrupted logistics networks and limited supplies. 

Global markets were already collapsing from material and price shortages due to the international container shipping system and factory shutdowns. The coronavirus has reduced demand for transportation fuels and led to refinery shutdowns and production cuts, particularly in the United States and Europe. US propylene prices are at a 10-year high and inventories are about 50% lower than a year ago. 

Apart from the short-term consequences of the “storm”, the affected companies must consider the fundamental problems associated with limited production of glycol – especially propylene glycol (PG) and over-reliance on limited producers – namely LyondellBasell and BASF. Many companies have developed Coolflow DTX, a high performance non-toxic secondary refrigerant suitable for replacing PG in food cooling and cold storage systems. 

In terms of performance, DTX has very similar heat transfer and pumping characteristics to ethylene glycol, and subsequently enjoys several operational advantages such as low viscosity, low dosing rates, and smaller systems and on-site plant footprints, and it has been proven that costs Reduces energy by more than 10%. DTX maintains proper efficiency for low temperature systems previously not possible with propylene glycol – while improving fluid reliability and system life. 

DTX-based coolants are also used in various industrial and commercial sectors, where non-toxicity and low environmental impact are of high priority. The cost-saving benefits of dosing a new or existing system (upgrade) with DTX are particularly favorable in the current economic climate. For example, at current rates, if DTX were to replace PG in a proposed 20,000 liter system (protected to -15°C), savings of over 100% per installation could be achieved. 

Updated prices of propylene glycol in the world

While production costs have risen significantly, upstream prices have affected MPG production rates, and some major MPG manufacturers have decided to focus production and sales where the margins are best. The availability of MPG for industrial and pharmaceutical grades has decreased.Demand for industrial grade MPG (PGI) was strongly influenced by the effects of the coronavirus, with a declining trend. Drug uptake for USP grade was much higher and caused some vendors to focus more on USP than PGI.

MPG interest rates rose over a period of time, although producers monitored inventory and demand and raised rates at different times of the quarter. Recently, the market has intensified due to the restrictions offered by strong PO. Integrated PO manufacturers seem to favor higher priced polyols over MPG. As a result, the DPG of the joint product also tightened. As the global market intensified, more questions were asked from other regions.Demand for industrial materials for the construction industry improved and demand for detergents remained stable. DPG demand was generally slow, while MPG USP demand remained at its lowest. In recent months, this trend has been growing.

For several reasons, the release of MPG became more difficult. Hurricane Laura affected the Indorama facility in Port Nechs, Texas. The storm hit the area on August 27, causing a long-term power outage. Although electricity was restored in 2-3 weeks, market participants said supply was still limited in the coming weeks. Other producers, far from the path of Hurricane Laura, also had shortages because they were out of stock compared to other years in early summer.MPG demand increased, especially in the last month of the 2020 quarter. Like many other petrochemicals, MPG began an upward trend at the beginning and returned slowly in the following months as part of the economy reopened. After a further fall in 2020, propylene contracts began to rise, leading to an increase in MPG prices. Despite higher costs, market participants said demand was still high.

Propylene glycol market

The global market for propylene glycol is divided into petroleum glycol and bio. Oil-based propylene glycol is expected to dominate the global market due to its increasing use in the transportation, construction and manufacturing industries. Unsaturated polyester resin has dominated the global propylene glycol market in the global market of propylene glycol, followed by antifreeze, functional and pharmaceutical liquids. The growing construction and construction industry, coupled with increased investment in emerging economies for infrastructure development, is driving a growing propylene glycol market for unsaturated polyester resins. Food, beverages, cosmetics, and transportation are also factors in market growth.

What are the different types of propylene glycol?

Propylene glycol USP

 USP Propylene Glycol is approved for use in direct food and beverage applications. The USP-labeled product means that the product is packaged in accordance with USP certifications on approved food and beverage packaging approvals.

Inhibited propylene glycol

Corrosion-resistant inhibited propylene glycol designed for use in aqueous systems.

USP grade inhibited propylene glycol

 It is a commercial product of Dow Chemical and is propylene glycol for use in water systems in food grade facilities.

How to buy USP propylene glycol?

We always recommend buying USP propylene glycol concentrate. This is the most cost-effective way to buy propylene glycol, but in cases where the specifications require mixed glycol, diluted forms of propylene glycol can also be used.
