About N,N-dimethyl-p-toluidine
N,N-dimethyl-p-toluidine is a cosmetic ingredient used in product formulations. Its specific function may vary between products. Exercise caution due to limited available safety data.
Detailed Analysis
N,N-Dimethyl-p-toluidine is an aromatic amine closely related to N,N-dimethyl-p-phenylenediamine (which is prohibited under Annex II/1312) and shares the dimethylaniline core with other restricted hair dye intermediates. While not specifically listed in EU Annex II, its structural similarity to toxic hair dye amines (H351 suspected carcinogen) and lack of adequate cosmetic safety data place it in the 20–39 range. The ingredient serves primarily as a chemical intermediate in industrial synthesis, not as a functional cosmetic additive.
Known Concerns
- ⚠ H351: Suspected of causing cancer — structural alert for carcinogenicity
- ⚠ Aniline core — methemoglobinemia risk with dermal absorption
- ⚠ Structural similarity to prohibited hair dye intermediates
- ⚠ Insufficient cosmetic-specific safety data
Safety Score
Caution
Based on EU regulatory data, published safety research, and ingredient function analysis.
