SORBETH-4 TETRAOLEATE.

Valuable / SURFACTANT - CLEANSING, SURFACTANT - EMULSIFYING

Sorbeth-4 Tetraoleate is a versatile tetraester derived from oleic acid, sorbitol, and polyethylene glycol. Primarily functioning as an emulsifier and surfactant, it creates stable cosmetic formulations by expertly blending disparate oil and water phases. This ingredient also contributes to a refined product texture and a light, non-heavy feel on the skin.

Science

Mechanism of Action

As an emulsifier, Sorbeth-4 Tetraoleate operates by significantly reducing the surface tension between immiscible oil and water components, thereby facilitating the formation of stable emulsions. This property not only stabilizes the overall formula but also enhances its textural application and imparts a pleasant skin feel. Additionally, it can create a subtle, protective film on the skin, aiding in moisture retention without feeling heavy, and potentially improving the uniform penetration and distribution of other active ingredients.
