Propylene glycol Powder Usage and Synthesis.

Propylene glycol has a wide range of applications in several fields. In the food industry, propylene glycol is used as an emulsifier and wetting agent for bread and pastries, preventing hardening of food and mold growth. In the cosmetic industry, propylene glycol is used as a wetting agent and softening agent, and has good intermiscibility with fragrances, so it is also often used as a solvent and softening agent for cosmetics.

In the pharmaceutical industry, propylene glycol is used as a solvent, softener and excipient in the manufacture of various types of ointments and creams. In the aerospace industry, aqueous solutions of propylene glycol are used as effective antifreeze agents. In addition, propylene glycol is used as a humidifying agent for tobacco, as an anti-mold agent, as a solvent for lubricating oils in food processing equipment and as a solvent for food labeling inks.

Uses of Propylene glycol.

Used as drug carrier, granule drug agent. It can be used as moisturizer, softener and solvent in cosmetics. In the tobacco industry, it can be used as cigarette flavor, tobacco moisturizing agent, preservative, etc.

It can be used as solvent of flavor, food coloring, food packaging softener, food anti-adhesive agent, etc. in the industry. It can also be used in the production of unsaturated polyester resin, plasticizer, dehydrating agent, surfactant, curing agent, binder raw materials.

Propylene glycol is an important raw material for unsaturated polyester, epoxy resin, polyurethane resin, the dosage in this area accounts for about 45% of the total consumption of propylene glycol, this unsaturated polyester is used in large quantities for 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, antifreeze, lubricant and solvent in the food, pharmaceutical and cosmetic industries. In the food industry, propylene glycol reacts with fatty acids to form propylene glycol fatty acid esters, which are mainly used as food emulsifiers; propylene glycol is an excellent solvent for flavoring and coloring.

Propylene Glycol is often used as a solvent, softener and excipient in the manufacture of various types of ointments and creams in the pharmaceutical industry, and is also used as a solvent and softener in cosmetics due to the good intermiscibility between Propylene Glycol and various types of fragrances.

Preparation of Propylene glycol.

Product Method of Bulk Propylene glycol Powder.

1. Propylene oxide direct hydration method is pressurized non-catalytic hydrolysis method. It is produced by direct hydration of propylene oxide and water at 150-160℃ and 0.78-0.98MPa pressure, and the reaction product is evaporated and distilled to get the finished product.
2. Propylene oxide indirect hydration method is produced by indirect hydration of propylene oxide and water with sulfuric acid as catalyst.3. Propylene direct catalytic oxidation method.
