Science
Mechanism of Action
It stabilizes light-sensitive compounds by quenching singlet oxygen and acting as a triplet energy quencher, preventing UV filter breakdown. Additionally, it neutralizes free radicals, mitigating oxidative stress on skin cells.

Key findings
- 01 Reduced photo-oxidation in cosmetic matrices by 40%, outperforming benzophenone-3 in some formulations. Efficacy plateaus above this concentration for photo-oxidation.
- 02 Produced desired photostabilizing effects in sunscreens, enhancing critical UVA wavelength and boosting SPF by about 5 units.

- Vitamin C
Conflicts
- Strong acidic conditions
- Strong alkaline conditions
- Oxidizing agents
Safety
Safety Profile
In vitro tests indicate no significant cytotoxicity at cosmetic concentrations. It is generally well-tolerated with a favorable safety profile, though rare irritation at high concentrations is noted. It is a REACH Registered Substance.
