Science
Mechanism of Action
Functions as an m-diamine coupler that reacts with oxidizing agents and primary intermediates to form large, permanent pigment molecules within hair shafts through chemical coupling reactions
Research
Clinical Evidence
Medium confidenceN/A
Key findings
- 01 Safety evaluation in oxidative hair dye formulations showed no significant skin irritation at typical concentrations, with identification as potential skin sensitizer
Transparency
Dusting Analysis
Restricted to hair dye applications with specific regulatory limitations, making dusting practices irrelevant for skincare contexts
The Formula
Formulation
Stability
Maintains stability exclusively in alkaline conditions required for hair dyeing; becomes ineffective in acidic skincare environments and shows sensitivity to light and air exposure
Conflicts
- Strong oxidizing agents
- Acidic environments
- Formaldehyde donors
Safety
Safety Profile
Restricted exclusively to oxidative hair dye applications by CIR and European regulations, with 2% maximum on-head concentration for permanent hair dyes
