Science
Mechanism of Action
Functions as a primary intermediate in oxidative hair coloring by penetrating the hair cortex and forming reactive imines when exposed to hydrogen peroxide, which then couple with modifier molecules to create large, permanent pigment complexes
Research
Clinical Evidence
High confidenceN/A
Key findings
- 01 Demonstrated safety in oxidative hair dye formulations with on-head concentrations up to 1.0-1.5% when combined with hydrogen peroxide
Transparency
Dusting Analysis
Not applicable for skincare dusting analysis as this ingredient is exclusively used in hair coloring applications
The Formula
Formulation
Stability
Highly oxygen-sensitive and requires airtight packaging or antioxidants like sodium sulfite to prevent premature oxidation
Synergies
- hydrogen peroxide
- coupling agents
- sodium sulfite
Conflicts
- strong oxidizing agents (pre-application)
- nitrosating agents
