  • Polymers
  • CAS 9011-14-7
  • IUPAC: poly(methyl 2-methylpropenoate)

Poly(methyl methacrylate) (CAS 9011-14-7) appears in 1 of the 2,122 car-care products CarCareTruth tracks (as of August 2026).

PMMA (acrylic/Plexiglas-family polymer) carries no GHS health hazard classification. It is not listed by ACGIH, IARC, NTP, or California Prop 65. Present at 1-5% by weight in this formula as a co-resin alongside the primary polyurethane film-former.

Poly(methyl methacrylate), the acrylic polymer familiar from Plexiglas and cast acrylic sheet, appears here at 1-5% as a co-resin that adds hardness and optical clarity to the cured protective film. It is one of the most extensively studied plastics in commerce and carries no GHS hazard classification and no Prop 65 listing.

Because PMMA is a high-molecular-weight polymer rather than a small reactive molecule, it is not considered readily biodegradable, but at the trace concentration used in a wipe-on lens coating the total mass involved is negligible next to the primary polyurethane resin.
