Science
Mechanism of Action
Functions as a reactive coupler that combines with dye precursors in the presence of oxidizing agents like hydrogen peroxide to generate large, stable pigment molecules that penetrate and remain fixed within hair shaft structures
Research
Clinical Evidence
Medium confidence1%
Key findings
- 01 Safety evaluation in oxidative hair dye applications confirmed no consumer health risk at maximum permissible on-scalp concentration
Transparency
Dusting Analysis
Not applicable for general skincare formulations due to regulatory restrictions and specialized hair dye application
The Formula
Formulation
Stability
Exhibits severe stability limitations with complete degradation in organic solvents within one week and approximately 10% degradation in aqueous solutions within 48 hours, requiring acidic pH conditions for maximum stability
Conflicts
- Strong oxidizing agents
- Nitrosating compounds
Safety
Safety Profile
Approved exclusively for oxidative hair dye applications at concentrations not exceeding 1.0%, with regulatory prohibitions in Europe and Brazil for general cosmetic use due to sensitization potential
