PEG-40 Hydrogenated Castor Oil (CAS 61788-85-0) is a nonionic surfactant derived from hydrogenated castor oil reacted with 40–45 moles of ethylene oxide, forming polyethylene glycol (PEG) derivatives.
It appears as a pale yellow viscous liquid or paste with a faint odor, soluble in water, ethanol, and organic solvents, and has an HLB value of 13–16.
Widely used as an emulsifier, solubilizer, and dispersant, it enhances formulation stability in cosmetics (e.g., fragrances, creams), pharmaceuticals (e.g., drug delivery systems), and industrial applications (e.g., textiles, lubricants).
Its ability to stabilize oil-in-water emulsions and solubilize hydrophobic compounds like vitamins and essential oils makes it versatile . Regulatory bodies, including the FDA and EMA, recognize its safety for topical and oral use due to low toxicity and biocompatibility.
