About

A quaternary ammonium conditioning agent that helps soften and smooth hair and skin by depositing a positive charge onto surfaces.

PEG-3 Distearoylamidoethylmonium Methosulfate is a PEGylated quaternary ammonium compound used as an antistatic and hair conditioning agent in cosmetic formulations. It is not listed in EU Annex II (prohibited) or Annex III (restricted), but like all quaternary ammonium compounds, environmental persistence concerns apply to aquatic organisms. The PEG chain length of 3 is short, limiting potential for ethoxylation-related impurities.

Skin benefits

  • Conditions and softens hair and skin
