Product Description
Propylene glycol is scientifically named "1,2-propylene glycol", its chemical formula is C3H8O2 , and its molecular weight is 76.10. There is a chiral carbon atom in the molecule. The racemate is a hygroscopic viscous liquid, almost odorless, flammable, low toxicity, and slightly spicy. Its relative density is 1.0362 (25/4 °C), its melting point is -60 °C, and its boiling point is 188.2 °C. It is miscible with water, acetone, ethyl acetate and chloroform, and soluble in ether. Although it has little solubility for hydrocarbons, chlorinated hydrocarbons, and oils, it has stronger solubility than ethylene glycol. It is soluble in many essential oils, but not miscible with petroleum ether and paraffin oil. It is relatively stable to heat and light, and more stable at low temperatures. The boiling point of its L-isomer is 187 to 189°C, and the specific rotation [α] is D20-15.0°. It can be oxidized into propionaldehyde, lactic acid, pyruvic acid and acetic acid at high temperature.

Application
Propylene glycol is an organic solution that has a wide range of uses. The following are examples of its applications:
1.Pharmaceutical field
Propylene glycol can be used as a solvent for poorly soluble or water-soluble stable drugs to increase their stability and have quick-acting and extended-acting effects. Used as a solvent, softener and excipient in the manufacture of various ointments and ointments.
2.Food and Drink
Propylene glycol is a water solvent that can dissolve water-soluble fragrances, pigments, preservatives, vitamins, resins, etc. Mainly used as food emulsifier, it is also an excellent solvent for seasonings and pigments, used as stabilizer, coagulant, antidegradant, etc. in cakes, and also as softener and emulsifier for gum-based candy.
3.Flavors and fragrances, food additives
It can be used as a solvent and carrier for edible flavors. Used as a solvent for various spices, pigments, preservatives, and an extraction solvent for vanilla beans, roasted coffee grains, natural flavors, etc.
4.Cosmetics, daily chemicals
Propylene glycol is used as a solvent and softener in cosmetics and can be found in almost all forms of makeup, hair care products, lotions, after-shave care products, deodorants, mouthwashes, and toothpastes. In cosmetics, toothpaste and soap, it is generally used as a wetting agent in combination with glycerin or sorbitol. Used as a moisture-conditioning and hair-leveling agent in hair dyes.
5.Industrial antifreeze
Industrial propylene glycol acts as a wetting agent and dissolving agent in chemistry, and is a main component of high-grade antifreeze.
6.Paints and coatings
Propylene glycol has the characteristics of low freezing point and can be mixed with water in any ratio. After mixing with water, it can greatly reduce the overall freezing point of the coating and enhance the antifreeze performance of the coating. Therefore, it is often used as an antifreeze in the coating to make the coating at 0 It won't freeze when it is high. Propylene glycol has good compatibility with water and other solvents and has a high boiling point. It is easy to achieve balance in water-based coating systems. It can also provide the fluidity of the coating and slow the drying of the coating.
