Propylene Glycol CAS 57-55-6 USP Grade

Product Description:

Propylene Glycol is a kind of colorless, transparent liquid, CAS number 57-55-6, formula C3H8O2.

Product Application: 

Its most important end use is in the production of unsaturated polyester resins that, in turn, gointo items that effect our daily lives, like water tanks, or our leisure time, like sailing boat. 

As a bacteriostatic agent, propylene glycol is similar to ethanol, and its efficacy in inhibiting mold is similar to that of glycerin and slightly lower than that of ethanol. Propylene glycol is commonly used as a plasticizer in aqueous film coating materials. An equal-amount mixture with water can delay the hydrolysis of certain drugs and increase the stability of the preparation. 15% to 30% propylene glycol solutions and semi-solid preparations can be used as antibacterial preservatives, about 15% propylene glycol topical preparations can be used as moisturizers, 10% to 30% propylene glycol aerosol Solvents, 10% to 25 % of propylene glycol oral solutions, 10% to 60% of injectable preparations, and 5% to 80% of topical preparations are used as solvents and co-solvents. [Stability and storage conditions] Extremely stable at room temperature, but oxidized when left open at high temperatures (above 280°C); chemically stable after being mixed with 95% ethanol or water; can be sterilized by autoclaving or filtration. bacteria. Propylene glycol is hygroscopic and should be stored in a cool, dry place in a sealed container away from light. [Incompatibility] It is incompatible with certain oxidants (such as potassium permanganate).

It canalso be used as plasticizer, surface active agent, emulsifying agent and demulsifying agent, mould inhibitor, antiseptic for fruit, ice inhibitor and moisture preserving agent for tobacco.
