POLYGLYCERYL-3 DIISOSTEARATE/IPDI COPOLYMER ●
TL;DR. This ingredient is a synthetic film-forming and pigment-dispersing polymer used to improve wear, adhesion, and suspension in color cosmetics and sunscreens. It can also help thicken oil phases and improve water resistance.
What does POLYGLYCERYL-3 DIISOSTEARATE/IPDI COPOLYMER do in a cosmetic formula?
This ingredient is a synthetic film-forming and pigment-dispersing polymer used to improve wear, adhesion, and suspension in color cosmetics and sunscreens. It can also help thicken oil phases and improve water resistance.
Is POLYGLYCERYL-3 DIISOSTEARATE/IPDI COPOLYMER clean?
From a clean-beauty perspective, it has friction because stricter standards often limit synthetic film-forming polymers and may screen for residual reactive monomers from manufacture. In finished formulas, the polymer itself is generally low in skin reactivity.
Is POLYGLYCERYL-3 DIISOSTEARATE/IPDI COPOLYMER sustainable?
It is made from a mix of fatty ester inputs and petrochemical-derived reactive linker chemistry, so sourcing is only partly renewable. Large synthetic polymers of this type are not expected to be readily biodegradable, which raises environmental persistence concerns.
Is POLYGLYCERYL-3 DIISOSTEARATE/IPDI COPOLYMER COSMOS-approved?
It is not permitted under COSMOS-natural or COSMOS-organic as a synthetic polymer made through petrochemical-style chemistry. Its fit with Green Chemistry is weak because renewable content is only partial and end-of-life biodegradability is limited.
How does POLYGLYCERYL-3 DIISOSTEARATE/IPDI COPOLYMER work chemically?
The molecule is a high-molecular-weight urethane-linked copolymer with branched hydrophobic side chains, giving oil compatibility, adhesion, and flexible film formation. Use levels are supplier- and formula-dependent, but it is typically handled as an oil-phase polymer for anhydrous or emulsion systems and is more relevant to solvent and oil compatibility than to formula pH.
