PEG-10 SORBITAN LAURATE.

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

PEG-10 Sorbitan Laurate is a polyethylene glycol derivative of sorbitan laurate, primarily recognized for its versatile surfactant properties. It efficiently forms stable emulsions, solubilizes other ingredients, and contributes to gentle cleansing formulations, making it a key component in a wide array of personal care products.

Summary

Emollient Emulsifying Surfactant/Cleansing Solubilizer

Science

Mechanism of Action

This ingredient functions by significantly reducing the surface tension between immiscible substances, such as oil and water, enabling them to mix stably into an emulsion. As a solubilizer, it helps dissolve components that would typically be insoluble in a given solvent. Furthermore, its surfactant capabilities allow it to aid in cleansing by facilitating the emulsification and rinse-off of oils and dirt from the skin or hair.

The Cosmetic Ingredient Review (CIR) Expert Panel concluded that PEG Sorbitan/Sorbitol Fatty Acid Esters, including PEG-10 Sorbitan Laurate, are safe at concentrations up to 25%. However, use on damaged skin is cautioned. Potential trace amounts of 1,4-dioxane, a by-product of ethoxylation, can be mitigated through stringent purification processes. The ingredient is listed in the FDA Global Substance Registration System (GSRS).
