About 1,3-Benzenediamine, 4-methyl-, hydrochloride (1:1)
1,3-benzenediamine, 4-methyl-, Hydrochloride (1:1) is a cosmetic ingredient used in product formulations. Exercise caution due to limited available safety data.
Detailed Analysis
This aromatic diamine salt is closely related to the banned dihydrochloride form (30200) and serves as a primary intermediate in oxidative hair dyeing. Although less hazardous than the 1:2 salt, it remains a strong contact sensitizer requiring strict dose controls. The EU SCCS has evaluated toluene-2,5-diamine salts and established safe concentrations for hair dye use. Any cosmetic formulation must comply with the SCCS opinion and applicable Annex III limits.
Known Concerns
- ⚠ Strong skin sensitizer potential
- ⚠ Requires compliance with EU SCCS safe concentration limits
- ⚠ Restricted to rinse-off hair dye applications in EU
