About

A tertiary-amine oxide used as a foam booster and conditioner in cleansers. Effective, but it is eye-irritating and the amine chemistry needs nitrosamine-formation controls.

Skin benefits

  • Foam booster in surfactant systems
  • Thickens cleansers and shampoos
  • Conditioning effect on hair

Known concerns

  • Moderately skin-irritating at higher %
  • Severely eye-irritating in unrinsed contact
  • Potential for nitrosamine formation if paired with nitrosating agents
