About

Distearoylisopropyl Dimonium Methosulfate is a cosmetic ingredient. Exercise caution due to limited available safety data.

As a di-long-chain quaternary ammonium salt (ditallow/di stearyl relative), this ingredient adsorbs to negatively charged surfaces to provide lubrication and antistatic effects. Methosulfate is a commonly used counterion for quaternary ammonium compounds in cosmetics and is considered safe at rinse-off concentrations. EU Regulation 1223/2009 permits quaternary ammonium compounds with chain lengths typical of this substance.
