Chemistry, Properties & Perfumer Guide

The Chemistry

C10-16-alkyldimethyl amine oxides belong to the amphoteric surfactant class, containing both hydrophilic and hydrophobic groups. They’re synthesized through oxidation of tertiary amines using hydrogen peroxide. The alkyl chain length (C10-C16) determines solubility and foaming properties. These compounds exhibit pH-dependent behavior, acting as nonionic surfactants at high pH and cationic at low pH.
