HYDROGENATED CASTOR OIL LAURATE.

Valuable CAS 85711-76-8 / SKIN CONDITIONING, SKIN CONDITIONING - EMOLLIENT

Hydrogenated Castor Oil Laurate is a multifaceted ester recognized for its skin conditioning and emollient properties. It effectively moisturizes the skin by creating a protective barrier against moisture loss. In its PEGylated variations, its functional profile expands to include surfactant, emulsifying, and solubilizing capabilities.

Science

Mechanism of Action

This ingredient functions by forming a hydrating, occlusive layer on the skin's surface, which significantly reduces transepidermal water loss and enhances skin moisturization. Its emollient qualities contribute to a softer, smoother skin texture. Furthermore, as a derivative of castor oil, it contains ricinoleic acid, a compound associated with anti-inflammatory effects that may help soothe the skin. When chemically modified through PEGylation, Hydrogenated Castor Oil Laurate also serves as an effective surfactant, emulsifier, and solubilizer, improving product stability and performance.
