The scientific name of Mono propylene glycol is "1,2-propanediol". There is a chiral carbon atom in the molecule. The racemic form is a hygroscopic viscous liquid with a slight spicy taste. Miscible in water, acetone, ethyl acetate, and chloroform, soluble in ether. Soluble in many essential oils, but not miscible with petroleum ether, paraffin, and fats. It is more stable to heat and light, and more stable at low temperatures. Propylene glycol can be oxidized to acetaldehyde, lactic acid, pyruvic acid, and acetic acid at high temperatures.
It can be used as raw material for resins, plasticizers, surfactants, emulsifiers and demulsifiers, and also as antifreeze and heat carrier
Packing: 215kgs iron drum
