This article deals with the presence of monopropylene glycol in solvents.Monopropylene glycol is a synthetic organic solvent obtained by refining crude oil. This petroleum mixture is made from distilled alkanes, naphthenes and aromatic compounds. It has moisturizing properties, meaning that it can absorb hard water molecules.It is used in a wide range of industries because of its low toxicity, with a freezing point that decreases when mixed with water.Monopropylene glycol is a colorless, odorless liquid that is biologically safe. The Food and Drug Administration (FDA) has classified it as an additive that is generally considered safe.This substance is found in many different food products and can be identified by examining the list of ingredients.In residential and commercial constructions, it is used primarily for the construction of building panels, bathroom components, appliances and tanks, corrosion-resistant pipes and ducts. Other markets include the production of yachts, passenger cars and trucks, as well as recreational vehicles and major accessories.Another major use of monopropylene glycol is as a substance in engine coolants, lubricants and antifreeze. It replaces ethylene glycol as the base fluid for aircraft formulations and refrigerants in the food industry.Monopropylene glycol is preferred over ethylene glycol due to its much lower toxicity.
Monopropylene glycol is used as a solvent and extractant. Solvent applications include alkyd resins, printing inks, and coatings.It is an ideal solvent for mixing chemicals when producing photographic films. It can also be used as a solvent in the manufacture of oral, topical and injection programs for the pharmaceutical industry, as it is not soluble in water. This substance is added to food colors and flavors due to its sweet aroma and solvent properties. Monopropylene glycol is also used as a solvent in paints, detergents, inks, nail polishes, and cleaners and household cleaners.The semiconductor industry uses solvents called Cellosolves that contain monopropylene glycol.Monopropylene glycols or MPGs can be mixed with aliphatic alcohols and low molecular weight ketones in all proportions. It is slightly soluble in aromatic hydrocarbon solvents and can only be mixed with aliphatic hydrocarbon solvents.Side effects of solvent monopropylene glycolThis solvent has the smell and taste of kerosene. Exposure to this solvent usually occurs when you use a product such as a diluent that contains it and its vapors enter your lungs or eyes. Although some of the compounds in the solvent evaporate quickly, if they enter the inhaled air, they enter the bloodstream and the chemicals that make up the solvent are absorbed by various tissues in the body, including the brain. It is not clear how quickly solvent components leave the body. The observed physiological effects are:Burning eyes, skin and throat, central nervous system (CNS) disorders such as dizziness, headache and nausea can cause long-term CNS reactions, seizures, chronic bronchitis, kidney damage in men and possibly cancer.The World Health Organization recommends a maximum of 11.4 mg of monopropylene glycol per pound of body weight (25 mg / kg) per day.While monopropylene glycol is generally considered safe, you can avoid it if you are allergic or want to reduce your intake.If you are allergic to propylene glycol, it is important to tell your doctor or pharmacist before taking certain medications this is a Applications of monopropylene glycol.
Excess streams from the production of monopropylene glycol are primarily responsible for diffusion into air, water and soil. It can enter the environment when used as a runway and aircraft defrost. It can also enter the environment through the disposal of products containing it. There is probably not much in the air. Small amounts that may enter the air decompose rapidly. If it escapes into the air, it takes between 24 and 50 hours for the released half to decompose. Monopropylene glycol can be thoroughly mixed with water and immersed in soil. It can decompose relatively quickly (within a few days to a week) in surface water and soil.
