HYDROXYPROPYL ARGININE CETEARYL ETHER.

Valuable / SURFACTANT - CLEANSING

HYDROXYPROPYL ARGININE CETEARYL ETHER is a multifunctional ingredient that acts as an effective skin and hair conditioner. It functions as a surfactant, enabling the stable mixing of oil and water, and contributes to gentle cleansing formulations.

Summary

Antistatic Hair Conditioning Skin Conditioning Surfactant/Cleansing Emulsifier

Science

Mechanism of Action

This ingredient primarily serves as a skin conditioning agent, actively supporting the maintenance of skin health. As a surfactant, it reduces the surface tension of liquids, which is crucial for emulsification, allowing oil and water phases to combine stably. This property also aids in its contribution to effective skin cleansing. The arginine component within the molecule is recognized for its additional conditioning and moisturizing benefits on the skin.

Stability

As an arginine derivative, HYDROXYPROPYL ARGININE CETEARYL ETHER effectively functions as an emulsifier, capable of forming stable oil-in-water (O/W) or water-in-oil (W/O) emulsions. Its emulsifying performance is reportedly robust and not significantly impacted by the presence of salts, allowing for compatibility across a variety of salt-containing formulations. It can be synergistically combined with other surfactants to achieve optimal cleansing properties and enhance skin tolerance. Furthermore, it demonstrates compatibility with common cosmetic additives including thickeners, preservatives, UV absorbing agents, pigments, perfumes, and crude botanical extracts.
