Science
Mechanism of Action
Functioning as a surfactant, PEG-2 Ricinoleate facilitates the mixing of oil and water phases in cosmetic products. Its PEGylated structure allows it to attract and bind moisture to the skin by forming hydrogen bonds with water molecules, thereby acting as a humectant. The ricinoleate component, derived from castor oil, contributes emollient benefits by establishing a protective barrier that minimizes trans-epidermal water loss, leaving skin feeling supple and moisturized.

Stability
PEGylated compounds like PEG-2 Ricinoleate generally exhibit robust stability, resisting hydrolysis or degradation in oxygen-free conditions. Its emulsifying capability is crucial for stabilizing formulations, preventing the separation of oil and water.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has deemed PEG-2, among 130 related PEGylated oils, safe for use in cosmetics at current concentrations, provided formulations are non-irritating. While related PEG-2 Dilaurate and Laurate esters are safe up to 25%, and other PEGylated oils up to 100%, a specific maximum for PEG-2 Ricinoleate is not stated beyond the 'safe as used' general classification. It is important to note that some PEG ingredients may enhance the penetration of other substances into the skin, necessitating careful consideration of overall formulation safety. Originating from petrochemistry, PEGs may contain trace amounts of 1,4-dioxane and unreacted ethylene oxide; manufacturers must employ appropriate purification to ensure these byproducts are removed.
