PEG-60 Glyceryl Isostearate
What is PEG-60 Glyceryl Isostearate?
PEG-60 Glyceryl Isostearate is a polyethylene glycol derivative formed by attaching 60 ethylene oxide units to glyceryl isostearate, which itself comes from esterifying glycerol with branched-chain isostearic acid derived from vegetable or animal fats. This creates a molecule with a lipophilic (oil-loving) fatty acid portion and highly hydrophilic (water-loving) polyether chains. In cosmetics, it appears mainly in rinse-off products like shampoos, body washes, facial cleansers, and micellar waters. It functions as a surfactant by reducing surface tension between water, oils, and soil particles, allowing micelles to form that encapsulate and lift away impurities for easy rinsing. As an emulsifier, it stabilizes oil-in-water mixtures, preventing separation and ensuring consistent texture during use.
