About

Trichlormethine is a nitrogen-mustard chemotherapy/warfare agent — EU Annex II banned, IARC-carcinogen-class, never permitted in cosmetics.

Trichlormethine (CAS 555-77-1; hydrochloride 817-09-4; N-oxide 126-85-2; and related salts such as 6138-32-5) is tris(2-chloroethyl)amine, the original chemical-warfare nitrogen mustard and the parent of several chemotherapy alkylating agents (e.g., mechlorethamine). It covalently crosslinks DNA, causing vesication on skin and cytotoxic/myelosuppressive effects systemically. Nitrogen mustards as a class are IARC Group 1 human carcinogens. Trichlormethine is explicitly listed in the EU Cosmetics Regulation (EC) 1223/2009 Annex II as a substance prohibited in cosmetic products. Presence in a cosmetic ingredient database is a compliance red flag, not a cosmetic input. Score 0 reflects total prohibition and extreme hazard.
