Is Bis-Hpma Poly(Methylpentanediol Adipate)/Ipdi Copolymer vegan?

This synthetic urethane polymer is made by condensing 3-methyl-1,5-pentanediol and adipic acid into a prepolymer, reacting it with isophorone diisocyanate (IPDI), and end-capping with hydroxypropyl methacrylate (HPMA). It is used in cosmetics as a film-forming agent.

An ingredient is considered vegan if it contains no animal-derived components at any point in its production.
