SODIUM CETEARYL SULFATE.

Valuable CAS 59186-41-3 / CLEANSING, FOAMING, SURFACTANT - CLEANSING

Sodium Cetearyl Sulfate is a versatile anionic surfactant utilized to effectively cleanse the skin, generate lather, and stabilize diverse cosmetic formulations. Its amphiphilic structure enables the stable emulsification of oil and water, thereby optimizing product texture and performance.

Summary

Cleansing Foaming Surfactant Emulsifying Dispersing Solubilizing Wetting Stabilizing

Science

Mechanism of Action

This ingredient functions by reducing the surface tension between two immiscible components, such as oil and water, acting as a highly effective surfactant. It serves as an emulsifying agent, promoting the stable dispersion of disparate liquids, and as a dispersing agent, ensuring the uniform distribution of particles within a formulation. Additionally, it operates as a solubilizing, wetting, and cleansing agent, efficiently attracting and lifting dirt and oils from the skin for effortless rinsing, while also contributing to foam generation in rinse-off products. These inherent properties are crucial for enhancing formulation stability and preventing ingredient separation.

The Cosmetic Ingredient Review (CIR) Expert Panel concluded Sodium Cetearyl Sulfate is safe for use in cosmetics under current practices and concentrations. Studies confirm no acute oral toxicity. While the undiluted substance may induce mild eye irritation, a 20% aqueous solution has been shown to be non-irritating to both skin and eyes. It demonstrates significantly less skin irritability compared to Sodium Lauryl Sulfate, with safety assessments for related alkyl sulfates considering concentrations up to 29% in cleansing formulations.
