SODIUM ACRYLOYLDIMETHYLTAURATE/ITACONATE COPOLYMER

Substance information

"Sodium..." refers to a sodium salt. "Acryloyl" refers to the acryloyl group H2C=CH-CO- (the acyl residue of the acrylic acid). "Methacryloyl" refers to the methacryloil group (methacryloil-). Taurine (2-aminoethanesulfonic acid) is a conditionally essential, non-protein, sulfur-containing beta-amino acid found widely in mammalian tissues and fluids. Taurine has various physiological functions, including acting as a neurotransmitter and antioxidant. Taurate is the deprotonated, anionic form of taurine. Under physiological conditions with a close to neutral pH, taurine predominantly exists as taurate, making it the primary form found in mammalian organisms. Taurates surfactants are composed of a hydrophilic head group, consisting of N-methyltaurine (2-methylaminoethanesulfonic acid) and a lipophilic building block, consisting of a long-chain carboxylic acid (fatty acid), both linked via an amide bond. The fatty acids used could be lauric (C12), myristic (C14), palmitic (C16) or stearic acid (C18), but mainly mixtures of oleic acid (C18:1) and coconut fatty acid (C8 – C18) are used. This group of surfactants exhibit unique properties, such as ready biodegradability, low toxicity, and excellent foaming capabilities. The methyl group is one of the simplest arrangements of atoms in organic chemistry which can be found as a moiety of numerous organic molecules. The name „methyl“ is derived from methane, the member of the alkane hydrocarbon group with the lowest molecular weight. The methane molecule contains four hydrogen atoms each one bound to a central carbon atom. The methyl group is not an independent chemical entity and contains only three hydrogen atoms, the fourth binding site is generally used for binding to a larger, mainly organic molecule. Like all alkanes, methyl groups exhibit a particularly low chemical reactivity. Polymer or copolymer based on esters of the itaconic acid (methylene succinic acid) and possibly other monomers. "Copolymer" refers to a polymer composed of several different (mostly two) basic units (monomers).

Function(s) of this ingredient in cosmetic products

DISPERSING

Facilitating the dispersion of solids in liquids. They function primarily by coating the solid through the process of adsorption, thus changing the surface characteristics of the suspended solid.
