About
A doubly-hydroxylated, PEG-10 alkoxylated stearyl quaternary ammonium salt designed to provide mild conditioning with excellent hydrophilicity balance.
This ingredient is a complex multi-functional quaternary ammonium with two primary hydroxypropyl groups, a PEG-10 (approximately 10 ethylene oxide units) chain, and a stearyl (C18) alkyl group. The di-hydroxypropyl groups enhance water solubility and skin compatibility, while PEG-10 moderates cationic charge density. No specific EU CosIng restriction exists. PEG chain raises standard by-product concern (ethylene oxide, 1,4-dioxane). The dihydroxypropyl moiety is unusual and limits available safety data, placing score in the 60s.
Skin benefits
- Mild conditioning with better moisture-retention than standard quaternaries
- Improved solubility enabling higher activity in aqueous formulations
- Antistatic performance in hair care
Known concerns
- Residual ethylene oxide and 1,4-dioxane from PEG synthesis
- Limited independent safety data for the di-hydroxypropyl substituent
- Skin irritation possible in sensitized individuals
