Dusting Analysis
This ingredient is not used in skincare formulations and would not be subject to cosmetic dusting practices
The Formula
Formulation
Stability
Exhibits maximum stability in highly alkaline conditions typical of professional hair dye systems (pH 9-10.5), degrades when exposed to direct UV light and loses activity in acidic environments
Conflicts
- Strong oxidizing agents outside controlled reactions
- Acidic pH environments
- Direct sunlight exposure
Safety
Safety Profile
EU SCCP evaluation determined safety at 1.0% maximum in finished hair dye products post-mixing, but classified as potential contact allergen with documented sensitization potential
