Quaternium-82 (inci)

Quaternium (see also polyquaternium) refers to complex quaternary ammonium compounds. Quaternary ammonium compounds, also known as quats, have quaternary nitrogen atoms, i.e. all four hydrogen atoms of the ammonium ion (nitrogen atom) are replaced by organic residues. The compounds are therefore cationic, i.e. they have a positive charge. "dioleate" denotes an ester of oleic acid in the side chain of the quaternary ammonium compound.

Quaternium-82 is used in cosmetic formulations. The mixture acts as an antistatic agent (reduces static charges by neutralizing the electrical charge on the surface of e.g. hair), skin care product and hair conditioning agent (makes hair easy to comb, smooth, soft and shiny and gives it volume).
