PEG-15 Glyceryl ricinoleate is a nonionic surfactant and emulsifier derived from castor oil fatty acid and polyethylene glycol. It is widely used in cosmetics, personal care formulations, pharmaceutical preparations, and industrial formulations as an emulsifier, solubilizer, dispersing agent, and conditioning ingredient. It improves oil-water compatibility and enhances formulation stability.
