Dioleoylethyl Hydroxyethylmonium Methosulfate
What is Dioleoylethyl Hydroxyethylmonium Methosulfate?
Dioleoylethyl Hydroxyethylmonium Methosulfate is a synthetic quaternary ammonium salt featuring two oleoyl chains from oleic acid, a fatty acid sourced from plant oils like olive or sunflower. Its structure includes a hydroxyethyl group and methosulfate counterion, enabling surfactant properties. Commonly found in rinse-off hair care formulations such as conditioners, leave-in treatments, and styling aids. It works through electrostatic attraction: the positively charged molecule binds to the negatively charged hair keratin, especially after anionic shampoo cleansing. This adhesion creates a protective, hydrophobic layer that lubricates the cuticle, lowers surface tension, diminishes inter-fiber friction, neutralizes static buildup from dry environments, and reflects light for enhanced luster. Its mild nature suits frequent use without heavy residue.
