Common Name(s): Amine oxide amphoteric,foam booster,ph-sensitive co-surfactant

CAS Number: N/a

DESCRIPTION

What It Does: Provides ph-sensitive amine oxide foam boosting, thickening, and conditioning.

Why It's Used: Amine oxide multifunctional — the unique ph-switching character (cationic/zwitterionic) makes amine oxides multifunctional ingredients providing foam enhancement, viscosity building, and conditioning from one ingredient at different ph conditions.

How It Works: Fatty amide + dimethylaminopropylamine + h2o2 → n-oxide. ph-switch: cationic ph<5, zwitterionic ph>6. foam boosting: mixed micelle synergy. thickening. conditioning. biodegradable. low irritation.

Typically Found In: Shampoos,body wash,foam boosting

SCIENTIFIC NOTE

Amine oxide foam boosting mechanism: at neutral ph, zwitterionic amine oxide co-micellises with anionic surfactants forming elongated micellar rods from the mixed charge system. rod-shaped micelles create viscoelastic solutions with gel-like foam lamellae — providing enhanced foam stability and persistence. the amine oxide's zero net charge at neutral ph enables electrostatic complementarity with anionic head groups for optimal mixed micelle geometry.
