An ester of diglycerin and isostearic acid used as an emollient and emulsion stabiliser.
What it is
Polyglyceryl-2 tetraisostearate is the tetraester of isostearic acid with polyglycerin-2, a glycerol polymer with an average of two glycerol units. CosIng lists it as an emollient, emulsion-stabilising and skin-conditioning ingredient and a cleansing surfactant.
Where it is used
Found in lipsticks, lip balms, cleansing oils, creams and other oil-rich products.
Limits of interpretation
The INCI list shows which ingredients are present, not how much of each. Above 1%, ingredients are listed in descending order of weight; below 1% the order is free.
The 2 refers to the average number of glycerol units, so the raw material is a mixture of esters.
