Science
Mechanism of Action
PEG-60 Hydrogenated Castor Oil performs as an effective emulsifier, enabling the stable integration of disparate oil and water phases within a product. Its role as a solubilizer allows otherwise insoluble, oil-loving ingredients like fragrances to disperse evenly in water-based solutions. Functioning as a surfactant, it lowers surface tension, improving the wettability of water and aiding in the emulsification of oils and dirt for easier removal during cleansing. Furthermore, it enhances product stability by preventing separation and maintaining consistent texture, while potentially contributing to skin hydration by minimizing transepidermal water loss.

Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has affirmed the safety of PEGylated oils, including PEG-60 Hydrogenated Castor Oil, in current cosmetic applications when formulated to be non-irritating. A maximum reported use concentration of 18% has been observed in leave-on non-coloring hair products, with related PEGylated castor oils deemed safe up to 100%. Its safety is further supported by European Cosmetics Regulations and FDA approval for external use, with its base, castor oil, recognized by the FDA as a flavoring agent and indirect food additive.
