Dicocoylethyl Hydroxyethylmonium Methosulfate

What is Dicocoylethyl Hydroxyethylmonium Methosulfate?

Dicocoylethyl Hydroxyethylmonium Methosulfate is a synthetic quaternary ammonium salt featuring dicocoyl chains from coconut fatty acids, a hydroxyethyl group, and methosulfate counterion. It belongs to cationic surfactants commonly found in hair care products like conditioners, shampoos, and styling aids. In formulations, its positively charged molecule adheres to negatively charged hair keratin, creating a protective layer. This deposition reduces inter-strand friction, neutralizes static buildup by boosting conductivity, and imparts a lubricated surface for easier combing. Primarily designed for rinse-off applications, it delivers conditioning during use with some residual effect after rinsing, supporting hair's natural texture without heavy buildup.
