SORBETH-40 PENTAOLEATE.

Valuable / SURFACTANT - CLEANSING, SURFACTANT - EMULSIFYING

Sorbeth-40 Pentaoleate is a versatile, hydrophilic compound primarily functioning as an emulsifier and surfactant in skincare. It is engineered to effectively blend immiscible oil and water phases, ensuring product stability and preventing separation. Furthermore, it acts as a cleansing agent by facilitating the removal of surface impurities.

Summary

Emulsifying Cleansing Solubilizing

Science

Mechanism of Action

As a nonionic, hydrophilic surfactant, Sorbeth-40 Pentaoleate reduces the surface tension between disparate liquid components, enabling them to form and maintain stable emulsions. This property allows for the uniform dispersion of oil-based ingredients within water-based systems. Its surfactant activity also aids in cleansing by helping to solubilize and lift oils, dirt, and other environmental debris from the skin's surface.

The Cosmetic Ingredient Review (CIR) Expert Panel has concluded that Sorbeth-40 Pentaoleate is safe for use in cosmetic formulations at concentrations up to 25%. A crucial caveat advises against its application on damaged skin. While the ethoxylation process may introduce trace amounts of 1,4-dioxane, this can be controlled through rigorous purification. Related ingredients, such as Polysorbate 40, are recognized as Generally Recognized As Safe (GRAS) for food use by regulatory bodies like the FDA.
