Science
Mechanism of Action
Hydrogenated Castor Oil Behenyl Esters exerts its effects through multiple pathways. On the skin, it functions as an emollient, delivering a smooth, softened feel. As a derivative of hydrogenated castor oil, it forms a protective occlusive layer on the skin's surface, effectively minimizing transepidermal water loss. Its ricinoleic acid content contributes humectant properties, drawing and retaining moisture to boost hydration. Collectively, these actions enhance the skin barrier function and aid in the repair of the stratum corneum. Within formulations, it acts as a lipogelifying agent, contributing to a more solid texture, and as an emulsion stabilizer, ensuring consistent mixing of ingredients and extending product shelf life.

Stability
This ingredient is insoluble in water, primarily functioning as a lipogelifying and emulsion-stabilizing agent in oil-based systems. While a specific pH range for Hydrogenated Castor Oil Behenyl Esters is not provided, related hydrogenated castor oil derivatives are known for chemical stability across a broad pH spectrum (acidic to alkaline). Prolonged exposure to high heat may induce separation, but the formulation can typically be re-homogenized.
Safety
Safety Profile
