Polyglyceryl-10 Pentaisostearate

What Polyglyceryl-10 Pentaisostearate is & what it does

Polyglyceryl-10 Pentaisostearate is a non-ionic emulsifier made by joining a ten-unit polyglycerol backbone with isostearic acid esters. In skincare and sunscreen formulas it helps blend oil and water phases and stabilizes the emulsion, giving a smooth, spreadable texture. A notable property is that, as a polyglyceryl ester, it is generally considered gentle and is often chosen for mild, low-irritation products.
