About
A PEGylated quaternary ammonium salt that functions as a conditioning agent, delivering anti-static benefits to hair while providing some antimicrobial properties.
PEG-2 Stearmonium Chloride is a ethoxylated stearyl quaternary ammonium compound (Polyquaternium-2 structural class). The PEG-2 moiety reduces the cationic charge density compared to non-alkoxylated analogues, improving mildness. Not specifically restricted in EU Annexes, but PEG-chain ingredients are subject to by-product scrutiny (ethylene oxide, 1,4-dioxane). SCCS notes general concerns for residual ethylene oxide impurities in PEG ingredients.

- Improves softness and manageability of treated hair
- Mild antimicrobial properties from quaternary ammonium moiety
Known concerns
