PEG-40 SORBITAN LAURATE.

Valuable CAS 9005-64-5 / SURFACTANT - CLEANSING, SURFACTANT - EMULSIFYING

PEG-40 Sorbitan Laurate is a polyethylene glycol derivative primarily functioning as an emulsifier, surfactant, and solubilizer in cosmetic formulations. It is crucial for creating stable, homogeneous products by facilitating the uniform dispersion of oil and water-based ingredients, ensuring smooth application and consistent texture.

Science

Mechanism of Action

This ingredient operates by significantly lowering the surface tension between dissimilar liquid phases, such as oil and water. As an emulsifying agent, it stabilizes emulsions, preventing separation of components. Its surfactant properties assist in the cleansing process by helping water mix with oily impurities and dirt, enabling their removal. Additionally, it acts as a solubilizing agent, allowing poorly soluble substances like active ingredients, fragrances, and colorants to dissolve effectively within a solvent system.
