Derived from EU CosIng regulatory status, PubChem hazard data and published research. How we score.
A quaternary ammonium conditioning agent that softens skin and hair and reduces static. It is effective but, like other quats, can irritate eyes and sensitive skin at higher use levels.
Skin benefits
- Quaternary ammonium conditioning agent that gives soft feel on skin and hair
- Improves wet and dry combing in hair products
- Reduces static and adds antimicrobial preservation support
Known concerns
- Quaternary ammonium compounds are common skin and eye irritants at high levels
- Some quats are associated with contact sensitization
- Methosulfate counter-ion is generally low-concern but adds little benefit beyond formulation
- Not biodegradable as readily as plant-derived conditioners
