DECYLAMINE OXIDE.

Valuable CAS 2605-79-0 / ANTISTATIC, CLEANSING, HAIR CONDITIONING, SURFACTANT - CLEANSING, SURFACTANT - FOAM BOOSTING, SURFACTANT - HYDROTROPE

Decylamine Oxide is an amphoteric surfactant utilized in precision skincare for its effective cleansing, foam-boosting, and emulsifying capabilities. It adeptly reduces surface tension, facilitating the removal of impurities and stabilizing product formulations to enhance overall texture and performance.

Summary

Cleansing Foam Boosting Emulsifying Hair Conditioning Surfactant Antistatic Agent Hydrotrope

Science

Mechanism of Action

As an amphoteric surfactant, Decylamine Oxide possesses an amphiphilic structure that significantly reduces surface tension in aqueous environments. This property enables it to blend immiscible oil and water phases, acting as a potent emulsifier and solubilizer for hydrophobic compounds. It functions primarily as a cleansing agent, improves foam quality and stability, and conditions the skin, while also contributing a mildness effect that can minimize irritation from stronger anionic surfactants.

Stability

Decylamine Oxide exhibits excellent stability across a broad pH range, specifically between 5.0 and 9.0. It is compatible with both acidic and alkaline systems and demonstrates resistance to degradation from bleach or other oxidative agents.

Synergies

  • Enhances product mildness and reduces potential irritation when combined with stronger anionic surfactants.

Conflicts

  • Strong oxidizing agents (particularly in concentrated forms or specific industrial contexts)

The Cosmetic Ingredient Review (CIR) Expert Panel has determined Decylamine Oxide to be safe for 'rinse-off' cosmetic products under current usage conditions. For 'leave-on' applications, its concentration is restricted to a maximum of 3.7%. While generally considered mild in properly formulated products, higher concentrations of Decylamine Oxide can potentially induce skin and eye irritation.
