Benzotriazole UV Absorber

  • UV stabilizers
  • CAS 2440-22-4

Benzotriazole UV Absorber (CAS 2440-22-4) appears in 5 of the 1,812 car-care products CarCareTruth tracks (as of June 2026).

Low toxicity UV stabilizer. Used in sunscreens, plastics, and automotive coatings. No acute health hazards at car-care concentrations.

Benzotriazole derivatives are industrial UV absorbers that convert harmful UV radiation into harmless heat. They're the same technology used in automotive clear coats, sunscreens, and plastic products to prevent UV-induced degradation.

In car care products like 303 Aerospace Protectant, they provide molecular-level UV blocking that prevents plastic and rubber from fading, cracking, and becoming brittle. More effective than simple silicone-only approaches because they address the root cause (photon absorption) rather than just physical shielding.
