Polyethylene glycol is abbreviated as "PEG". A polymer compound formed by intermolecular dehydration condensation of ethylene glycol. The chemical formula is HOCH2(CH2OCH2)nCH2OH. where n is greater than 4. The average molecular weight is 200-7000. The numbers following commercial polyethylene glycols indicate average molecular weights. For example, polyethylene glycol-400 means that the average molecular weight of the commercial polyethylene glycol is about 400.
Colorless viscous liquid or white solid. Soluble in water and many organic solvents, easily soluble in aromatic hydrocarbons, slightly soluble in aliphatic hydrocarbons
Application:
Used as analytical reagents, also in the pharmaceutical industry;
For softeners, lubricants, etc.;
It is used as a matrix in medicine and cosmetics, and as a dispersant, lubricant, emulsifier, etc. in rubber, metal processing, pesticide and other industries;
Medium for organic synthesis, humectant for daily cosmetic industry, inorganic salt solubilizer, viscosity modifier, etc.;
Used in cosmetic, pharmaceutical, chemical fiber, rubber, paper, paint, electroplating, pesticide, metal processing and food processing industries
Polyethylene glycol with high relative molecular weight (Mr >2000) is suitable for lipsticks, deodorant sticks, soaps, shaving soaps, foundations and beauty cosmetics.
