Science
Mechanism of Action
Operates through direct molecular binding to keratin structures, creating stable color complexes without requiring traditional oxidative activation pathways for its primary effects
Research
Clinical Evidence
Medium confidence1.5%
Key findings
- 01 Demonstrated minimal dermal penetration (0.21-0.36%) in controlled absorption studies using carboxymethylcellulose vehicle systems
- 02 Showed non-irritating properties in standardized rabbit irritation protocols using propylene glycol carriers
Transparency
Dusting Analysis
Primarily utilized in specialized hair care applications rather than general skincare formulations, reducing likelihood of concentration manipulation
The Formula
Formulation
