What it is
This ingredient is made by ethoxylating glyceryl isostearate, producing a water-dispersible nonionic emulsifier. In sunscreens it helps combine oil and water phases and can solubilize oily materials and fragrances into otherwise aqueous systems. It contributes to stable emulsions with a light, comfortable feel.
Safety & warnings
PEG glyceryl esters of this type are generally well tolerated and have low irritation potential at typical use levels. As with other ethoxylated ingredients, they are used in finished formulas designed to meet cosmetic quality standards.
Origin & sourcing
Synthetic ingredient produced by reacting glyceryl isostearate, derived from glycerin and isostearic acid, with ethylene oxide.
