Polyglyceryl-2 Isostearate/Dimer Dilinoleate Copolymer

What Polyglyceryl-2 Isostearate/Dimer Dilinoleate Copolymer is & what it does

Polyglyceryl-2 Isostearate is a non-ionic emulsifier made by joining isostearic acid to a short polyglycerol backbone. In a skincare or sunscreen formula it helps blend the oil and water phases into a stable emulsion and can give the product a smooth, soft feel. It is a glyceryl-ester surfactant often chosen as a gentler, polyethylene-glycol-free alternative for emulsifying creams and lotions.
