About
Isononamidopropyl Ethyldimonium Ethosulfate is a cosmetic ingredient used in product formulations. Its specific function may vary between products. Exercise caution due to limited available safety data.
An isononanoic (C9 branched fatty acid) amide derivative of a quaternary ammonium ethosulfate, functioning as a hair and skin conditioning agent. The branched-chain isononanoyl group reduces crystallization issues compared to linear chains. No specific EU Annex II or III restrictions apply to this compound class. Assessment aligns with structurally similar behenyl and stearyl quaternary ammonium conditioning agents recognized as safe at typical use concentrations.
