Dilinoleic Acid/Butanediol Copolymer
What this ingredient generally does
A film-forming ingredient that leaves a thin, even layer on the skin as the product dries. It also works as a plasticiser, keeping that film flexible rather than stiff.
Reviewed before publication. This note describes function in a formulation — nothing else.
