Science

Mechanism of Action

Functioning as a non-ionic surfactant, this ingredient efficiently bridges immiscible oil and water phases, creating stable emulsions and effectively solubilizing lipophilic components within aqueous systems. On the skin, it establishes a subtle, protective film, significantly diminishing transepidermal water loss and reinforcing the skin's natural barrier function. Its humectant properties further attract and retain moisture, contributing to enhanced hydration and supporting the penetration of other active ingredients.

The Cosmetic Ingredient Review (CIR) Expert Panel deemed PEG-20 Hydrogenated Castor Oil PCA Isostearate, along with 129 chemically related PEGylated oils, safe for cosmetic use under current practices, provided formulations are non-irritating. Related ingredients, such as PEG-30 and PEG-40 Hydrogenated Castor Oil, have been cleared for concentrations up to 100%. The FDA monitors for 1,4-dioxane, a potential byproduct of ethoxylation, with purification steps employed to mitigate its presence. It is permitted for use in Europe under the general provisions of the Cosmetics Regulation.
