What it is
This ingredient is a polyglyceryl-10 backbone esterified with a blend of fatty acids, including dimer dilinoleic, stearic, and hydroxystearic acids, yielding a nonionic emulsifier. The mixed fatty-acid profile gives it the ability to stabilize emulsions and disperse pigments, which is useful in mineral sunscreens and tinted bases. It also contributes a conditioning, cushioned feel to the formula.
Safety & warnings
Polyglyceryl fatty-acid esters are generally mild, nonionic, and well tolerated, with a low irritation and sensitization profile. They do not carry the fragrance-allergen concerns associated with botanical aromatics.
Origin & sourcing
Synthetic; produced by esterifying polyglycerin-10 with plant- or fatty-acid-derived materials.
Questions everyone asks
What is its main job in a formula?
It works as a nonionic emulsifier that holds oil and water phases together and helps disperse pigments in mineral and tinted products.
Is it harsh on skin?
Polyglyceryl esters of this type are typically mild and well tolerated, making them suitable for sensitive-skin formulations.
