Science
Mechanism of Action
This ingredient operates by lowering the surface tension between disparate phases, such as oil and water, facilitating their combination. As an emulsifier, it stabilizes these mixtures, preventing separation. Its solubilizing capacity allows oil-soluble components, including active ingredients, fragrances, and colorants, to disperse uniformly in aqueous systems. Additionally, it may contribute to skin hydration and smoothness by forming a delicate protective barrier that helps reduce trans-epidermal moisture loss.

Stability
This ingredient is effective in forming stable emulsions, preventing the separation of oil and water phases, thereby enhancing product integrity and shelf life. It serves as an excellent solvent and solubilizer for various lipophilic compounds, including active ingredients, perfume oils, and colorants, particularly in aqueous and low-alcohol systems. For optimal results, it is recommended to allow the mixture to cool before incorporating heat-sensitive ingredients.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has deemed 130 PEGylated oil ingredients, including PEG-50 Hydrogenated Castor Oil, safe for use in cosmetic products at current concentrations, provided they are formulated to be non-irritating. Related PEG-castor oil ingredients have been found safe up to 100% concentration. A potential concern regarding 1,4-dioxane, a by-product of the ethoxylation process, is noted, but its presence can be effectively mitigated through rigorous purification steps. The FDA lists castor oil as a permitted food additive and PEG Castor Oil ingredients for indirect use in textiles.
