Polyglyceryl-10 Decaisostearate

A decaglycerin ester of isostearic acid used as an emulsifier and emollient in cosmetic formulas.

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.
