Science
Mechanism of Action
Operates as a high-efficiency triplet-state quencher and singlet oxygen inhibitor. It intercepts energy from UV-excited molecules and endogenous chromophores like Protoporphyrin IX, safely converting that energy into negligible heat before it can react with oxygen to generate damaging Reactive Oxygen Species (ROS).
Research
Clinical Evidence
High confidence1%
Key findings
- 01 Clinical testing at 0.5% concentration demonstrated a 25% reduction in visible light-induced free radicals and a significant decrease in inflammatory markers IL-6 and IL-1α.
- 02 Research at 1.0% concentration confirmed the maintenance of over 90% UVA absorbance in Avobenzone-based formulas after exposure to 10 MED of radiation.
Transparency
Dusting Analysis
Due to its advanced technical profile, it is often included at negligible levels for marketing claims. While bio-activity begins at 0.5%, a concentration of 1.0% is required for robust photostabilization of sunscreens.
The Formula
Formulation
Stability
An exceptionally stable liquid ester; resistant to photodegradation and maintains performance across standard cosmetic pH ranges.
Synergies
- Avobenzone
- Retinol
- Protoporphyrin IX
- Vitamin E
Conflicts
- Anhydrous aqueous systems
- Strong oxidizing agents
Safety
Safety Profile
Classified as a functional light stabilizer rather than an active UV filter; currently listed in the EU CosIng database without specific restrictive caps up to recommended use levels.
