Science
Mechanism of Action
Operating primarily as a nonionic surfactant, emulsifier, and solubilizer, PEG-20 Castor Oil creates stable oil-in-water emulsions. Its hydrophilic nature, characterized by an HLB value of 10.5, facilitates the even dispersion of lipophilic components within aqueous systems, effectively solubilizing active ingredients and fragrances. On the skin, it supports barrier function, delivering a notable moisturizing effect, and has the potential to enhance the penetration of other beneficial ingredients. It also acts as a consistency enhancer and softening agent.

Safety
Safety Profile
The CIR Expert Panel affirms PEGylated Oils, including PEG-20 Castor Oil, are safe for cosmetic use at current concentrations when formulated to be non-irritating. While trace amounts of 1,4-dioxane, a by-product of ethoxylation, may occur, manufacturers can control this through purification. Castor oil, the base ingredient, is recognized as safe by the FDA, and PEG Castor Oils are permissible under European Cosmetics Regulation.
