Dosage and range of propylene glycol - Tianyuan polymer chemical raw materials

The small editor of the antioxidant manufacturer today takes you to know about the amount and scope of propylene glycol, propylene glycol is an important raw material for unsaturated polyester, epoxy resin, polyurethane resin, accounting for about 45% of the total consumption of propylene glycol, the unsaturated polyester is widely used in surface coatings and reinforced plastics. Propylene glycol is flammable, but it has less toxicity and less irritation to the human body. Moreover, propylene glycol has good viscosity and hygroscopicity, and is non-toxic, so it is widely used as a moisture absorber, antifreeze, lubricant and solvent in the food, medicine and cosmetics industries.

In the food industry, propylene glycol reacts with fatty acids to form propylene glycol fatty acid ester, which is mainly used as a food emulsifier; propylene glycol is an excellent solvent for flavoring agents and pigments. Propylene glycol is commonly used in the pharmaceutical industry to manufacture various ointments, solvent ointments, excipients and excipients, etc., because propylene glycol and various fragrances have better miscibility, so it is also used as a cosmetic solvent and softener. Propylene glycol, which is common in moisturizing products, is a water-based moisturizer synthesized by petrochemicals, which is a small molecule moisturizing ingredient that can reduce the viscosity of glycerol, and due to the addition of glycerol, the amount of propylene glycol can be reduced, and the stimulation can also be reduced.

The amount of propylene glycol added in cosmetics is less than 5%. Polyols make the product more refreshing and comfortable. 1, dipropylene glycol toxicity is low, miscible with water, suitable for animal injection preparations, for some insoluble substances, propylene glycol is mainly used for dissolution, its dosage is generally 50%-80%, and with some other non-human use of solvents, for some substances dissolved in water but the stability of the substance is poor, propylene glycol plays a role in auxiliary dissolution and stability, and its dosage is generally 20%-50%;
