Ingredient
AMMONIUM ACRYLOYLDIMETHYLTAURATE/LAURETH-7 METHACRYLATE COPOLYMER
Substance information
"Ammonium..." refers generally to an ammonium salt. "Acryloyl" refers to the acryloyl group H2C=CH-CO- (the acyl residue of the acrylic acid). "Methacryloyl" refers to the methacryloil group (methacryloil-). "Methyl" mostly refers to methanol (methyl alcohol) as alcoholic component or generally the methyl group as the smallest hydrocarbon residue with one carbon atom. Dimethyl-, trimethyl- etc refer to two, three or more methyl groups. Taurates are N-acyl derivatives, esters or salts of taurine (2-aminoethanesulfonic acid). "Laureth-" refers to a PEG-(polyethylene glycol-) ether of lauryl alcohol. The number behind "laureth-" refers to the average number of molecular units -CH2-CH2-O-. Methacrylates are polymers or copolymers based on methacrylic acid and / or its esters. "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.
