Polyglyceryl-10 Distearate ●
TL;DR. This ingredient is a nonionic oil-in-water emulsifier and co-emulsifier that helps blend oils with water and improve cream or lotion stability. It can also add a soft, cushioned skin feel and help disperse oily ingredients.
What does Polyglyceryl-10 Distearate do in a cosmetic formula?
This ingredient is a nonionic oil-in-water emulsifier and co-emulsifier that helps blend oils with water and improve cream or lotion stability. It can also add a soft, cushioned skin feel and help disperse oily ingredients.
Is Polyglyceryl-10 Distearate clean?
From a clean-beauty perspective, it is generally well tolerated, PEG-free, and not a common sensitizer. The main quality questions are feedstock origin and whether manufacturing controls minimize residual catalysts or byproducts.
Is Polyglyceryl-10 Distearate sustainable?
This material is commonly made from glycerin-derived building blocks and C18 fatty acids that may be plant-sourced, often from palm, rapeseed, or other vegetable oils. It is expected to be readily biodegradable, with the main sustainability consideration being traceable, responsibly sourced fatty-acid feedstocks.
Is Polyglyceryl-10 Distearate COSMOS-approved?
It is generally permitted under COSMOS-natural and COSMOS-organic when made from approved natural-origin feedstocks and compliant esterification processing. It fits Green Chemistry reasonably well because it is made by ester formation, can use renewable inputs, and has good biodegradability.
How does Polyglyceryl-10 Distearate work chemically?
The molecule is a nonionic diester with a highly hydrophilic multi-glycerol backbone and two long C18 fatty chains, giving it oil-in-water emulsifying behavior without ethoxylation. Typical use levels are about 0.5% to 5%, and it is broadly stable in normal cosmetic pH ranges but can hydrolyze under strongly acidic or alkaline conditions.
