What is Polyglyceryl-3 Diisostearate?
Polyglyceryl-3 Diisostearate is a synthetic compound used primarily as an emulsifier. It is typically produced by the esterification of polyglycerin and diisostearic acid, resulting in a substance that helps water and oil-based ingredients mix well together.
In cosmetics and skincare, it is often added to formulas to improve product texture and stability. The health evidence mostly regards it as safe for topical application, though comprehensive long-term data is limited.
When you see Polyglyceryl-3 Diisostearate on a label, it indicates that the product likely aims for a smooth and even application, which is crucial in makeup for consistent coverage.
