POLYGLYCERYL-3 DIISOSTEARATE ●
TL;DR. This ingredient is a nonionic emulsifier and dispersing agent, especially useful for water-in-oil emulsions, anhydrous balms, color cosmetics, and mineral sunscreen systems. It helps wet pigments and minerals while adding a soft, cushiony skin feel.
What does POLYGLYCERYL-3 DIISOSTEARATE do in a cosmetic formula?
This ingredient is a nonionic emulsifier and dispersing agent, especially useful for water-in-oil emulsions, anhydrous balms, color cosmetics, and mineral sunscreen systems. It helps wet pigments and minerals while adding a soft, cushiony skin feel.
Is POLYGLYCERYL-3 DIISOSTEARATE clean?
It is generally well tolerated, with low sensitization concern and little restricted-list friction in clean-beauty frameworks. The main quality check is supplier transparency around residual catalysts, residual monomers, and plant feedstock origin.
Is POLYGLYCERYL-3 DIISOSTEARATE sustainable?
This material is typically made from glycerin-derived units and fatty acids, often from vegetable oils, so sourcing can be renewable when the supply chain is documented. It is expected to be readily biodegradable because it is an ester-based, non-silicone, non-fluorinated material.
Is POLYGLYCERYL-3 DIISOSTEARATE COSMOS-approved?
It is generally permitted in COSMOS-natural and COSMOS-organic formulas when the raw material meets feedstock and processing requirements. Its Green Chemistry fit is solid, since it can use renewable inputs, performs at low use levels, and breaks down through ester biodegradation pathways.
How does POLYGLYCERYL-3 DIISOSTEARATE work chemically?
The molecule is a polyglycerol ester built from a short glycerol oligomer and branched C18 fatty acid chains, giving it low HLB behavior suited to water-in-oil systems. Typical use is about 1 to 5% as a primary emulsifier, or 0.5 to 3% as a co-emulsifier or pigment wetting agent, with good stability in oils and sensitivity mainly to strong acid or alkaline hydrolysis.
