as a raw material for resins, plasticizers, surfactants, emulsifiers and demulsifiers, can also be used as antifreeze and heat carrier

used as GC stationary liquid, solvent, antifreeze, plasticizer and dehydrating agent
carrier solvent; Wetting agent; Humectant; Anti-caking agent; Antioxidant; Tissue improver; surfactants; Stabilizers; Thickeners; Dough conditioners; Emulsifiers; Flavoring agents; Excipients; Processing aids. GB 2760~96 is classified as a food processing aid. Mainly used in a variety of spices, pigments, preservatives, solvents, vanilla beans, roasted coffee grains, natural flavor extraction solvent. Candy, bread, packaging meat, cheese and other moisturizing, softener. Can also be used as noodles, core fillings of anti-mildew additives. In the milk to add 0.006%, can make the heating of the same flavor, made of white and shiny packaging tofu, fried volume expansion.
propylene glycol is an intermediate of the fungicide difenoconazole.
as a solvent, preservatives, pigments, antioxidants and other food additives insoluble in water can be dissolved in it, and then added into food, it has moisturizing and anti-freezing effects on food. China's regulations can be used for cakes, the maximum use of 3.0g/kg.
propylene glycol is an important raw material for unsaturated polyester, epoxy resin and polyurethane resin, and the dosage in this area accounts for about 45% of the total consumption of propylene glycol. This unsaturated polyester is widely used in surface coatings and reinforced plastics. Propylene glycol has good viscosity and hygroscopicity and is non-toxic, so it is widely used as a hygroscopic agent, an anti-freezing agent, a lubricant and a solvent in the food, pharmaceutical and cosmetic industries. In the food industry, propylene glycol reacts with fatty acids to produce propylene glycol fatty acid esters, which are mainly used as food emulsifiers. Propylene glycol is an excellent solvent for condiments and pigments. Propylene glycol in the pharmaceutical industry is often used to produce all kinds of ointment, ointment solvent, softener and excipient, due to propylene glycol and all kinds of spices have good mutual solubility, so also used as a solvent and softener cosmetics, etc. Propylene glycol is also used as a solvent for tobacco moisturizers, mildewproofing agents, food processing equipment lubricants, and food marking inks. An aqueous solution of propylene glycol is an effective anti-freeze agent.
as a drug carrier, granule drug agent. It can be used as a moisturizer, softener, solvent, etc. in cosmetics. Tobacco industry can be used as tobacco flavor, tobacco moisturizing agents, preservatives, etc. In the food industry, it is used as a solvent for flavor, food pigment, food packaging softener, food anti-adhesion agent, etc. Can also be used for the production of Unsaturated Polyester Resin, plastic plasticizer, dehydrating agent, surfactant, curing agent, Binder of raw materials. Can also be used in paints, pesticides, coatings and other industries
aviation de-icing fluids, refrigerants and antifreeze agents, food and spices, fragrances, cosmetics and personal health care products, heat transfer fluids, hydraulic and brake fluids, paints and coatings, pet food/animal feed, pharmaceuticals, polyurethane, unsaturated polyester resin, etc.
Solvents, organic synthesis, antifreeze, plasticizer, bactericide. Standard for gas chromatographic analysis. Gas chromatography stationary liquid (the highest temperature of 150 deg C, the solvent for chloroform), separation and analysis of alcohols, esters and ketones.
