3-NITRO-4-AMINOPHENOXYETHANOL.

Questionable CAS 50982-74-6 / HAIR DYEING

A substituted aromatic amine compound primarily developed as a direct hair colorant rather than a skincare active. This low molecular weight molecule can penetrate biological tissues but shows limited skin absorption (0.42%) and poses potential sensitization risks through protein complex formation.

Summary

Colorant

Science

Mechanism of Action

Functions as a non-oxidative colorant that penetrates cellular structures through its small molecular size, bypassing the need for chemical activation. On skin contact, it may act as a hapten, forming complexes with skin proteins that could trigger delayed-type hypersensitivity reactions in predisposed individuals.
