PEG-10 HYDROGENATED CASTOR OIL ISOSTEARATE.

Valuable / SURFACTANT - EMULSIFYING, VISCOSITY CONTROLLING

PEG-10 Hydrogenated Castor Oil Isostearate is a non-ionic surfactant, emulsifier, and viscosity controller derived from castor oil. It is engineered to blend immiscible liquids, creating stable cosmetic formulations and ensuring even product distribution.

Summary

emulsifying viscosity controlling surfactant solubilizer

Science

Mechanism of Action

This ingredient functions by reducing the surface tension between different phases within a cosmetic product, primarily facilitating the stable dispersion of oil in water or vice versa. As an emulsifier, it stabilizes emulsions, preventing separation of components. Additionally, it contributes to product aesthetics by modulating viscosity, making textures either thicker or thinner as desired.
