Polyglyceryl-2 Triisostearate

What Polyglyceryl-2 Triisostearate is & what it does

Polyglyceryl-2 Triisostearate is an oil-soluble emulsifier and emollient made by esterifying polyglycerin-2 with isostearic acid. In sunscreen and skincare formulas it helps stabilize water-in-oil emulsions and gives products a smooth, cushiony spreadability. It is a polyglyceryl ester, a family valued as gentle, PEG-free emulsifiers.

Is Polyglyceryl-2 Triisostearate safe?

Polyglyceryl-2 Triisostearate is widely used in cosmetics as an emulsifier and emollient and is generally considered well tolerated when used as directed. It is a polyglyceryl ester, a family valued as mild, PEG-free alternatives. As with any ingredient, individual sensitivity is possible, so patch testing a new product is sensible.

Does Polyglyceryl-2 Triisostearate clog pores?

Polyglyceryl-2 Triisostearate is an oil-based emollient, and rich emollients can feel heavy on very oily or acne-prone skin. There is no strong, consistent comedogenicity data published for this specific ester. Whether a finished product feels pore-clogging depends on the full formula, so trying it on a small area first is a good idea.

Is Polyglyceryl-2 Triisostearate vegan?

Polyglyceryl-2 Triisostearate is made from polyglycerin and isostearic acid, both of which can be sourced from plant oils, so the ingredient itself can be plant-derived. However, fatty acids may in principle come from animal fats, so the source depends on the supplier. Check with the brand if a fully vegan product is important to you.
