Mono propylene glycol is a special propylene glycol (Foodgrade USP) for cooling and heating installations. This product is made on the basis of hygroscopic environmentally compatible propylene glycol. The propylene glycol contains inhibitors and low foaming additives against rust and scale deposition and is non-corrosive which protects the inner walls of pipes against corrosion, product aging, also in aluminum pipes. The liquid can be added without any problem to systems that already have a glycol-based coolant. In the following, we want to introduce you to industrial propylene glycol.
Along with other glycols and glycerol, industrial propylene glycol is a humectant (hydrating) and delivery ingredient used in cosmetics.
propylene glycol is really industrial antifreeze and that it’s the major ingredient in brake and hydraulic fluids. In fact, research from toxicologists has shown that propylene glycol and similar ingredients don’t present a health risk for people when used in cosmetics. In cosmetics, industrial propylene glycol is used in small amounts to keep products from melting in high heat or from freezing. It also helps active ingredients penetrate skin. In the amounts used in cosmetics, it’s not a concern in the least. The Cosmetic Ingredient Review Board and other groups have analyzed all of the toxicology data and exposure studies concerning topical application of propylene glycol as commonly used in cosmetics products. Their conclusion was that it is safe and does not pose a health risk to consumers.
Industrial Propylene glycol is used in the food processing industry, refrigeration and air-conditioning installations, the automotive industry and solar energy. propylene glycol has been designated as non-toxic and has the following advantages:
• Inhibitors and additives: protect against rust
• Propylene glycol does not contain phosphates, amines and nitrites.
• Food processing industry
• Cooling and air-conditioning installations
• Automotive
• Solar energy
The first grade is used in the food industry for food colourings and flavourings and is also a classified humectant food additive (E1520). There are also many applications in the cosmetics industry that use this solvent, specifically personal care products including shampoos, bubble baths, baby wipes and as a moisturiser in make-up.
The second is industrial grade MPG which has a variety of uses but the main application is as an antifreeze and aircraft wing and runway de-icer which is because its freezing point lowers upon mixing with water. It is also used in heat transfer liquids such as engine coolants. Monopropylene Glycol is additionally used in the pharmaceutical industry, examples include as a chemical intermediate in the production of high-performance unsaturated polyester resins used in paints and varnishes and as an excellent solvent utilised in printing inks. It is also used in the manufacturing of non-ionic detergents which are used in the petroleum, sugar-refining.
• Industrial propylene glycol is used as a heat transfer medium, to control viscosity, to dissolve active agents or protect against corrosion and pressure rupture.
• In paints and coatings, providing sustainable weather and wear protection.
• In liquid detergents, improving hygienic conditions.
Most consumers will get in contact with propylene glycol during their normal everyday life, when consuming personal care articles like creams, sprays, lotions, when enjoying soft drinks, sweets and other foods, or when taking a medicine or being vaccinated against a severe disease.
Propylene glycol has been used safely for more than 50 years in a large variety of applications. Studies have shown that propylene glycol has a very low degree of toxicity. No negative health effects from exposure to small amounts of propylene glycol have ever been observed. The authorities have approved the use of propylene glycol in sensitive applications such as in pharmaceuticals, food and cosmetics, and thus confirm its safety.
Industrial propylene glycol is used in refrigeration and air conditioning facilities, automotive industry and solar energy. It is a safe and non-toxic substance and is used in many industries.
