Polyglyceryl-2 Diisostearate
What Polyglyceryl-2 Diisostearate is & what it does
Polyglyceryl-2 Diisostearate is a polyglycerol ester of isostearic acid used as a nonionic emulsifier and emollient. In skincare and sunscreen formulas it helps blend oil and water phases, particularly in water-in-oil systems, and lends a smooth, conditioned feel. It is valued as a mild, plant-derivable alternative to some ethoxylated emulsifiers.
What does Polyglyceryl-2 Diisostearate do in skincare?
Polyglyceryl-2 Diisostearate works as a nonionic emulsifier and emollient, helping blend oil and water phases in a formula. It is especially useful in water-in-oil systems and lends a smooth, conditioned skin feel. In sunscreens it helps keep the emulsion stable.
Is Polyglyceryl-2 Diisostearate safe?
Polyglyceryl-2 Diisostearate is regarded as a mild emulsifier and is generally considered safe in cosmetic use. It is often chosen as a gentle alternative to some ethoxylated emulsifiers. As with any ingredient, sensitive skin may prefer a patch test.
Is Polyglyceryl-2 Diisostearate natural or synthetic?
Polyglyceryl-2 Diisostearate can be derived from plant sources, since both its polyglycerol and isostearic acid parts can come from vegetable oils, but it is produced through chemical processing. So it is best described as naturally derived rather than natural in its raw state. Sourcing varies by manufacturer.
