Ingredient
GLYCERETH-7 HYDROXYSTEARATE/IPDI COPOLYMER
Substance information
"Glycereth-" refers to a PEG-(polyethylene glycol-) ether of glycerin. The number behind "glycereth-" refers to the average number of molecular units -CH2-CH2-O-. Hydroxystearates are salts or esters of 12-hydroxystearic acid (12-hydroxy-1-octadecanoic acid). Polymer or copolymer based on isophorone diisocyanate (IPDI) and possibly other monomers. "Copolymer" refers to a polymer composed of several different (mostly two) basic units (monomers).

Background information on use in cosmetics
Polyethylene glycols (INCI: PEG-...) are poly condensation products of ethylene glycol, or polymerisation products of ethylene oxide. The number added to the name refers to the mean number of ethylene oxide units in the substance. The consistency of the PEG derivatives is increasingly solid with a growing degree of polymerisation. PEGs with a mean molar mass of up to 600 g/mol are liquid, up to 1,000 g/mol wax-like and from 4,000 g/mol solid wax-like substances. By mixing solid and liquid components, products of a creamy consistency are obtained which are used as water-free and water rinse-off bases. With growing molar mass water solubility and hygroscopicity (ability to absorb moisture) of the polyethylene glycols decrease.
