Polyglyceryl3 Diisostearate ●
TL;DR. This ingredient is a nonionic emulsifier and dispersing agent, mainly used to build water-in-oil emulsions and keep pigments, minerals, oils, and waxes evenly distributed.
What does Polyglyceryl3 Diisostearate do in a cosmetic formula?
This ingredient is a nonionic emulsifier and dispersing agent, mainly used to build water-in-oil emulsions and keep pigments, minerals, oils, and waxes evenly distributed.
Is Polyglyceryl3 Diisostearate clean?
It is generally well-tolerated, low in sensitization concern, and not a common clean-standard restricted-list ingredient. Clean-beauty scrutiny is usually about feedstock traceability rather than skin-safety controversy.
Is Polyglyceryl3 Diisostearate sustainable?
This material is commonly made from glycerin and fatty-acid feedstocks that may be vegetable-derived, with palm or other oil-crop sourcing possible depending on the supplier. It is expected to be biodegradable and does not carry the persistence concerns associated with many silicone or fluorinated materials.
Is Polyglyceryl3 Diisostearate COSMOS-approved?
It is permitted under COSMOS natural and organic frameworks when the raw materials and processing meet the standard’s requirements. From a Green Chemistry view, it aligns well because it can use renewable feedstocks, esterification chemistry, and a biodegradable molecular design.
How does Polyglyceryl3 Diisostearate work chemically?
The molecule is a nonionic ester built from a three-unit glycerol oligomer esterified with branched C18 fatty acids, giving it a low-HLB, lipophilic profile suited to water-in-oil systems. Typical use levels are about 1 to 5% as an emulsifier or dispersant, and it is generally stable across normal cosmetic pH ranges while being best protected from strong acid or alkaline hydrolysis conditions.
