Science
Mechanism of Action
Functions as a primary antioxidant by donating hydrogen atoms from its hydroxyl group to neutralize peroxy radicals, effectively breaking the chain reaction of lipid peroxidation and protecting formulation integrity
Research
Clinical Evidence
Medium confidence0.02%
Key findings
- 01 IFRA guidelines recommend maximum 0.02% in fragrance concentrates for optimal stability with minimal sensitization risk
- 02 Patch testing of 11,454 patients showed only 0.096% positive reactions at 2.0% concentration, demonstrating low sensitizing potential
Transparency
Dusting Analysis
Concentrations above 0.5% may increase risk of chemical leukoderma and skin sensitization, making higher percentages potentially problematic
