About

Pyridine-2,6- Diyldiamine is a cosmetic ingredient. Exercise caution due to limited available safety data.

Pyridine-2,6-diyldiamine (CAS 141-86-6) functions as a primary intermediate in oxidative hair dyeing processes. EU Regulation 1223/2009 Annex III restricts its use to concentrations below 0.1% as a constituent of substances or mixtures. The compound carries hazard statements including H301 (toxic if swallowed), H315 (causes skin irritation), H317 (may cause allergic skin reaction), H319 (causes serious eye irritation), H335 (may cause respiratory irritation), and H411 (toxic to aquatic life with long lasting effects). The pyridine heterocycle structure contributes to its moderate toxicity and environmental concern.
