About
A mild surfactant derived from isostearic acid that is commonly used in cleansing products with a favorable safety profile.
Isostearamidopropylamine Oxide is an amine oxide surfactant derived from isostearic acid (a branched-chain fatty acid), which distinguishes it from straight-chain counterparts like lauramidopropylamine oxide. The branched structure of isostearic acid typically results in milder surfactants with better mildness profiles than their straight-chain analogs. It is used in facial cleansers, body washes, and other personal care products for its cleansing and foaming properties. It is not specifically restricted under EU cosmetic regulation and is assessed as safe for cosmetic use at normal concentrations by analogy with similar amidopropylamine oxides.
Skin benefits
- Provides effective cleansing with a mild profile suitable for sensitive skin
- Functions as a foam booster and viscosity modifier in formulations
Known concerns
- Standard nitrosamine precursor monitoring applies
