Product Description

Propylene Glycol Tech Grade and USP Grade Manufacturer Supply PG Best Price

1. Product Description
The scientific name of propylene glycol is "1, 2-propylene glycol". There's a chiral carbon atom in the molecule. The racemate is a viscous liquid with easy hygroscopicity and a slightly spicy taste. Soluble in water, acetone, ethyl acetate and chloroform, soluble in ether. It can be dissolved in many essential oils, but it is not miscible with petroleum ether, paraffin and grease. More stable to heat and light, more stable at low temperatures. Propylene glycol can be oxidized to propionaldehyde, lactic acid, pyruvate and acetic acid at high temperatures.
