BEHENAMINE OXIDE.

Valuable CAS 26483-35-2 / CLEANSING, FOAMING, SURFACTANT - CLEANSING, SURFACTANT - HYDROTROPE

A long-chain (C22) amphoteric surfactant that serves as a high-performance conditioning agent and foam stabilizer. It is particularly valued in precision skincare for its ability to improve tactile skin feel and provide significant softening effects without compromising the formula's stability.

Science

Behenamine Oxide exhibits pH-dependent behavior: at neutral levels, it functions as a gentle cleanser and stabilizer, but when formulated at an acidic pH (below 7.0), it becomes protonated. In this cationic state, it binds effectively to the negatively charged keratin on the skin's surface, creating a protective, conditioning film that reduces static and smooths texture.

Key findings

  1. 01 Clinical observations indicate that concentrations between 1.5% and 6% yield the most significant improvements in skin smoothness and formulation silkiness.
  2. 02 Industrial data confirms its efficacy as a non-irritating softener in both leave-on and rinse-off dermatological preparations.

Because it functions as a structural conditioner and surfactant, concentrations below 0.5% are generally insufficient to provide the characteristic 'slip' and softening benefits associated with the ingredient.

Stability

Demonstrates excellent stability across a broad pH spectrum, though its cationic conditioning properties are most pronounced between pH 3.5 and 5.5. It also acts as a viscosity builder in surfactant-based systems.

Synergies

  • Nonionic surfactants
  • Cationic conditioning agents

Conflicts

  • Strong oxidizing agents
  • Highly anionic systems at low pH (potential complex formation)
