About
Dioleoylisopropyl Dimonium Methosulfate is a cosmetic ingredient used in product formulations. Its specific function may vary between products. Exercise caution due to limited available safety data.
This diquaternary ammonium salt features two oleoyl chains attached to an isopropyl dimonium nitrogen with methosulfate counterion. It functions as a conditioning agent in rinse-off cosmetic products. Di-quaternary ammonium compounds are known mild skin sensitizers and may cause eye irritation.
