Dusting Analysis
This ingredient primarily functions as a hair dye colorant and offers no identified benefits for skin. As it is also classified as a strong skin sensitizer, its inclusion in skincare formulations would be highly problematic due to the inherent risk of adverse reactions rather than providing any functional benefit.
The Formula
Formulation
Stability
The compound is prone to nitrosation, requiring nitrosamine content to be maintained below 50 ppb in formulations.
Conflicts
- nitrosating agents
Safety
Safety Profile
The SCCS (Scientific Committee on Consumer Safety) concluded that its use in non-oxidative hair dyes at a maximum concentration of 0.5% is generally safe, apart from its strong sensitizing potential. As a secondary amine, it is susceptible to nitrosation and must not be combined with nitrosating agents. Nitrosamine levels must be below 50 ppb.
