UV Stabilizer (benzotriazole-type)

  • UV stabilizers
  • CAS 104810-47-1
  • IUPAC: unknown (3M SDS lists only as 'UV Stabilizer'; CAS is consistent with a benzotriazole UV-absorber, commercially known as Tinuvin 1130)

UV Stabilizer (benzotriazole-type) (CAS 104810-47-1) 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 this ingredient, dermal LD50 estimated 2,000-5,000 mg/kg. Not classified as mutagenic in vitro. Present at 0.1-1% by weight, below the concentration typically associated with any GHS classification.

This component is disclosed in the 3M Quick Headlight Clear Coat SDS only as "UV Stabilizer" at CAS 104810-47-1, present at 0.1-1% by weight. That CAS number corresponds to a benzotriazole-family UV light absorber commercially sold under names like Tinuvin 1130; this class of chemistry works by absorbing incoming UV radiation before it can degrade the polymer film or the polycarbonate lens underneath it, which is the mechanism that gives a headlight clear-coat step its multi-month to multi-year durability against re-yellowing.

3M's own SDS toxicology tables report no significant skin or eye irritation for this ingredient at the tested doses, and no mutagenicity in vitro testing.
