Science
Mechanism of Action
On the skin, PEG-8 DI/TRIRICINOLEATE acts as a humectant, attracting and binding moisture to the stratum corneum to improve hydration. In formulations, its primary role is as an emulsifier, stabilizing oil-in-water or water-in-oil emulsions. Furthermore, it functions as a surfactant, reducing surface tension, and as a solubilizer, aiding in the homogeneous dispersion of lipophilic ingredients within aqueous systems.

Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has not conducted a specific safety assessment for PEG-8 DI/TRIRICINOLEATE. However, the base compound PEG-8 is considered safe for topical application on healthy skin within specified limits. Related PEGylated alkyl glycerides have been deemed safe when formulated to be non-irritating. It is important to note that PEG-8 may contain trace impurities such as ethylene oxide and 1,4-dioxane. The FDA has approved PEG-8 for certain limited food applications.
