Propylene Glycol
Name: 1,2-Propylene glycol
Molecular formula: C3H8O2
Relative Molecular weight: 76.09
CAS No.: 57-55-6
Packing:
Packed in galvanized iron drums, net weight 200Kg/drum. Or packed according to the clients' requirement
Storage and transportation:
Propylene Glycol is combustible. If coming into contact with oxidization it will burn. It should be stored in a cool and windy special warehouse far from fire and transported as a combustible chemical product.
Application:
Pharmaceutical industry: Propylene Glycol is used as the carrier of medicine and the agent for particle medicine.
Food industry: Propylene Glycol is used as solvent of perfume and edible pigment, emollient in food packing, and anti-adhesive,
Cosmetic industry: Propylene Glycol is used as humidor, emollient and solvent.
Tobacco industry: Propylene Glycol is used as tobacco flavor, lubricated solvent, and preservative.
Other fields: Propylene Glycol can be used as the raw material of non-saturated alkyd resin, plasticizer, dehydration, surface active agent, solidification agent, and cohesive agent.
Propylene Glycol is also used in paint industry, pesticide industry and dope industry etc.
