What it is
Adipic Acid/Diglycol Crosspolymer is a synthetic crosslinked polymer made by reacting adipic acid with a diglycol, forming a polyester network. In sunscreens and oils it serves as a film former and thickener that helps structure the product, bind ingredients together, and leave a smooth, even layer on skin. It is used at low to moderate levels as a texture and rheology aid.
Safety & warnings
Crosslinked polyester polymers of this type are generally non-irritating, are not absorbed through skin owing to their size, and are not considered comedogenic at normal use levels.
Origin & sourcing
Synthetic; produced by polycondensation and crosslinking of adipic acid with a diethylene glycol component.
Questions everyone asks
What does this crosspolymer do?
It thickens and binds the formula and helps form an even film, improving the texture and wear of sunscreens and oils.
Is it a UV filter?
No. It is a structural polymer and does not absorb UV radiation.
