There are medical grade and industrial grade. Medical grade propylene glycol is colorless clear viscous liquid; Odorless, slightly sweet taste; It has wetting ability; Can be miscible with water, ethanol or trichloromethane; Stable at room temperature, easy to produce propionic aldehyde, lactic acid, acetone, acetic acid at high temperature.

Propylene glycol Application:

Medical grade propylene glycol has a wide range of applications, which can be used in medicine, food, cosmetics and other fields.In the field of medicine, medical-grade propylene glycol is used as A solvent, extraction solvent and preservative for injectable and non-injectable pharmaceutical preparations and is capable of dissolubilizing substances such as corticosteroids, phenols, sulfonamides, barbiturates, vitamins A and D, most alkaloids and many anesthetics.

It can also be used as a bacteriostatic agent, and its effect of inhibiting mold is similar to glycerin;

Commonly used as plasticizer for water-borne film coating materials. In the food and cosmetics industry, medical-grade propylene glycol can be used as a carrier for emulsifiers and a solvent for fragrances. Because of its non-volatile nature, it is better than ethanol because it helps to maintain a stable aroma. The quality inspection standard of medical grade propylene glycol is: chloride ≤ 0.007%, sulfate ≤ 0.006%, moisture ≤ 0.2%, hot residue ≤ 0.007%, heavy metal ≤5ppm.

Industrial grade, mainly used to produce coating and unsaturated polyester resin, but also plasticizer, surfactant, emulsifier and demulsifier raw materials.
