Polyglycery-3 Diisostearate ●
TL;DR. This ingredient is a nonionic water-in-oil emulsifier and pigment-dispersing agent. It helps stabilize oil-rich formulas, sunscreens, and color cosmetics while adding emollient slip.
What does Polyglycery-3 Diisostearate do in a cosmetic formula?
This ingredient is a nonionic water-in-oil emulsifier and pigment-dispersing agent. It helps stabilize oil-rich formulas, sunscreens, and color cosmetics while adding emollient slip.
Is Polyglycery-3 Diisostearate clean?
Clean-beauty frameworks generally view it as low-friction because it is PEG-free, low-odor, and not a common sensitizer. The main review point is feedstock origin and residual processing aids, not the molecule itself.
Is Polyglycery-3 Diisostearate sustainable?
This material is typically made from glycerin-derived building blocks and branched fatty acids that can come from vegetable oils. It is expected to be readily biodegradable, with palm or other oil-crop sourcing as the main supply-chain question.
Is Polyglycery-3 Diisostearate COSMOS-approved?
It is permitted under COSMOS-natural and COSMOS-organic when made from approved natural-origin feedstocks and compliant processing. Its Green Chemistry fit is strong when vegetable-derived, with good biodegradability and no need for ethoxylation.
How does Polyglycery-3 Diisostearate work chemically?
The molecule is a nonionic ester built from a short glycerol oligomer backbone esterified with branched C18 fatty acid chains, giving it high oil affinity and a low HLB profile. Typical use is about 1 to 5% as an emulsifier or dispersant, and it is broadly stable across normal cosmetic pH because it is used mainly in the oil phase.
