PEG 400 CAS 25322-68-3

Characteristic

Colorless viscous liquid or white solid. Low toxicity! Soluble in water and many organic solvents, easily soluble in aromatic hydrocarbons, slightly soluble in aliphatic hydrocarbons.

Application:

Polyethylene glycol and polyethylene glycol fatty acid ester are widely used in cosmetics industry and pharmaceutical industry.

1. Polyethylene glycol (Mr<2000) with low molecular weight is suitable for use as a wetting agent and consistency regulator, for creams, lotions, toothpastes and shaving creams, etc., and for unwashed hair care products to give hair a filamentous shine.
   Polyethylene glycol (Mr>2000) with high molecular weight is suitable for lipstick, deodorant stick, soap, shaving soap, foundation and beauty cosmetics.


2. In cleaning agents, polyethylene glycol is also used as a suspension agent and a thickener.


3. In the pharmaceutical industry, it is used as a base for ointments, emulsions, ointments, lotions and suppositories. PolyethyleneGlycolNF (e.g., PolyethyleneGlycolNF, DowchemicalCo.) commercially available for food and drug use is better suited for cosmetics.


4. Polyethylene glycol is widely used in a variety of pharmaceutical preparations, such as injectable, topical, ocular, oral, and rectal preparations. Solid grade polyethylene glycol can be added to liquid polyethylene glycol to adjust the viscosity for local ointment; Polyethylene glycol mixture can be used as suppository substrate. The aqueous solution of polyethylene glycol can be used as a suspension aid or to adjust the viscosity of other suspension media. The combination of polyethylene glycol and other emulsifiers increases the stability of the emulsion.

In addition, polyethylene glycol is also used as film coating agent, tablet lubricant, controlled release material, etc.
