Product Description

Introduction
1,2-Propanediol is an organic compound with the chemical formula C3H8O2, which is miscible with water, ethanol and various organic solvents. Under normal conditions, it is a colorless viscous liquid, almost odorless, and smells slightly sweet. Propylene glycol can be used as a raw material for unsaturated polyester resin, and can be used as a wetting agent in combination with glycerin or sorbitol in cosmetics, toothpaste and soap. In hair dyes, it is used as a moisturizing and leveling agent, as an antifreeze, as well as in cellophane, plasticizer and pharmaceutical industry.


Use
1,2-Propanediol is an important raw material for unsaturated polyesters, epoxy resins, polyurethane resins, plasticizers and surfactants. The amount used in this regard accounts for about 45% of the total consumption of propylene glycol. Used extensively in surface coatings and reinforced plastics. 1,2-Propanediol has good viscosity and hygroscopicity, and is widely used as a hygroscopic agent, antifreeze, lubricant and solvent in the food, pharmaceutical and cosmetic industries. In the food industry, 1,2-propanediol reacts with fatty acids to form propylene glycol fatty acid esters, which are mainly used as food emulsifiers; 1,2-propanediol is an excellent solvent for condiments and pigments. Due to its low toxicity, it is used as a solvent for spices and food colorings in the food industry. 1,,2-Propanediol is commonly used in the pharmaceutical industry as a solvent, softener and excipient for the manufacture of various ointments and ointments, and as a solvent for blending agents, preservatives, ointments, vitamins, penicillin, etc. in the pharmaceutical industry . Because propylene glycol has good mutual solubility with various fragrances, it is also used as a solvent and softener for cosmetics, etc. 1,2-Propanediol is also used as a tobacco moisturizing agent, a mildew inhibitor, a lubricant for food processing equipment, and a solvent for food marking inks. Aqueous solutions of 1,2-propanediol are effective antifreeze agents. It is also used as tobacco wetting agent, mildew inhibitor, fruit ripening preservative, antifreeze and heat carrier, etc.
