About N'-Benzyl-N,N-dimethyl-N'-pyridin-2-ylethylenediammonium maleate
A cosmetic ingredient used in product formulations. Its specific function may vary between products. Exercise caution due to limited available safety data.
Detailed Analysis
This ethylenediamine derivative carries both tertiary amine (benzyl-dimethyl) and pyridyl substituents around a quaternary ammonium center, with maleic acid as the counterion. The pyridine ring and maleate create moderate structural alerts for skin sensitization and potential eye irritation. EU CosIng does not list this specific compound in Annex II or III, but the complex polyamine structure warrants precaution. Used in preservative or chelating systems at low concentrations.
Skin Benefits

Known Concerns
- ⚠ Skin and eye sensitization from pyridinium and quaternary amine structures
- ⚠ Maleic acid counterion — mild skin irritation possible
