Polyglyceryl-3 Disostearate ●
TL;DR. This ingredient is a nonionic emulsifier and co-emulsifier, mainly used to stabilize water-in-oil systems and improve pigment or oil dispersion. It also helps give creams and balms a smoother, richer feel.
What does Polyglyceryl-3 Disostearate do in a cosmetic formula?
This ingredient is a nonionic emulsifier and co-emulsifier, mainly used to stabilize water-in-oil systems and improve pigment or oil dispersion. It also helps give creams and balms a smoother, richer feel.
Is Polyglyceryl-3 Disostearate clean?
From a clean-beauty perspective, it is generally well tolerated and not a common sensitizer. It has little restricted-list friction, with the main review point being the origin and quality of the fatty feedstocks used to make it.
Is Polyglyceryl-3 Disostearate sustainable?
This material is commonly made from glycerin and fatty acid feedstocks that may be plant-derived, sometimes with palm or rapeseed supply-chain considerations. It is expected to be biodegradable and does not raise the persistence concerns associated with silicone or fluorinated film-formers.
Is Polyglyceryl-3 Disostearate COSMOS-approved?
It is generally compatible with COSMOS-natural and COSMOS-organic formulations when made from permitted natural-origin feedstocks and allowed processing routes. Its Green Chemistry profile is favorable because it can use renewable inputs, ester chemistry, and a biodegradation-prone structure.
How does Polyglyceryl-3 Disostearate work chemically?
The molecule is a nonionic diester with a glycerin-based hydrophilic head group and two long fatty chains, giving it a low HLB profile suited to water-in-oil emulsions. Typical use levels are often around 1 to 5% depending on the oil phase and emulsifier system, and it is broadly stable across normal cosmetic pH ranges because it is nonionic.
