What it is
Polyglyceryl-10 Decaisostearate is formed by esterifying a decaglycerin backbone with multiple isostearic acid units, producing a nonionic emulsifier with emollient character. It helps stabilize emulsions and disperse oils and pigments, and is useful in both water-in-oil and oil-in-water systems. The branched isostearate chains contribute a smooth, conditioning skin feel.
Safety & warnings
Polyglyceryl isostearate esters are generally well tolerated and used across many skincare and color cosmetic products. Sensitivity is uncommon.
Origin & sourcing
Synthetic ester typically made from plant-derived glycerin and isostearic acid.
