UV Stabilizer (hindered amine light stabilizer)

  • UV stabilizers
  • CAS 41556-26-7
  • IUPAC: unknown (3M SDS lists only as 'UV Stabilizer'; CAS pair is consistent with a hindered amine light stabilizer blend, commercially known as Tinuvin 292)

UV Stabilizer (hindered amine light stabilizer) (CAS 41556-26-7) appears in 1 of the 2,122 car-care products CarCareTruth tracks (as of August 2026).

SDS toxicology tables report no significant skin or eye irritation for the UV Stabilizer components. Present at under 0.5% by weight combined, below the concentration typically associated with any GHS classification.

Two related CAS entries in the 3M Quick Headlight Clear Coat SDS are both disclosed only as "UV Stabilizer" (CAS 41556-26-7, under 0.5% by weight, and a companion entry at CAS 82919-37-7, under 0.2% by weight). This CAS pair corresponds to a hindered amine light stabilizer (HALS) blend commercially known as Tinuvin 292, a chemistry family long used in automotive clear-coat paint precisely because it works by trapping free radicals generated by UV exposure rather than absorbing UV light directly, complementing a benzotriazole absorber for broader, longer-lasting protection.

3M's SDS toxicology data shows no significant irritation for this ingredient family at the tested doses. The two CAS numbers are grouped here because they represent variants of the same HALS chemistry disclosed at trace concentrations in the same formula.
