What it is
This ingredient is formed by esterifying decaglycerin (polyglyceryl-10) with two units of oleic acid, producing a mild nonionic emulsifier. Its highly hydrophilic polyglycerol head and oleic tails make it useful for stabilizing oil-in-water emulsions and improving texture in lightweight sunscreens. It also lends a soft, conditioned feel to the skin.
Safety & warnings
Polyglyceryl-10 esters are nonionic and generally considered mild and well tolerated, with low irritation potential. They are not associated with fragrance-allergen risk.
Origin & sourcing
Synthetic; made by combining plant-derived glycerin (as polyglycerin-10) with oleic acid, which is typically of vegetable origin.
Questions everyone asks
What is it derived from?
It is made by joining polyglycerin-10 with oleic acid, a fatty acid commonly sourced from vegetable oils.
Why use it in sunscreen?
It serves as a gentle emulsifier that stabilizes oil-in-water formulas and improves skin feel.
