About QUATERNIUM-82
A conditioning quaternary ammonium compound for hair — softens, detangles, and reduces static. Derived from hydroxypropyl groups and oleic acid esters.
Detailed Analysis
Quaternium-82 (CAS 65059-61-2 / 173833-36-8) is a diester quaternary ammonium compound consisting of bis(2-hydroxypropyl) amine with oleic acid ester groups and a methyl sulfate counterion. It functions as an antistatic and hair conditioning agent. Unlike harder quats (like cetrimonium chloride), the ester linkages make it biodegradable — the ester bonds hydrolyze in the environment. Ester quats are considered the more environmentally friendly generation of cationic hair conditioners. They deposit well on hair, reducing static and improving combability.
