Safety Data Sheet

Getting an SDS for 1,3,5-triazine-2,4,6-triam…

A Safety Data Sheet is written for a product, not for a substance: the supplier of the grade you actually buy issues it, so two suppliers of 1,3,5-triazine-2,4,6-t… issue two different sheets. That is why there is no single authoritative SDS for a substance to download — what there is, is the job of collecting the sheets for the products you hold and keeping them current as suppliers revise them.

04 · Precautionary statements

1,3,5-triazine-2,4,6-triamine precautionary statements

CLP Annex VI assigns 7 precautionary statements to 1,3,5-triazine-2,4,6-triam…. They are grouped the way a label groups them: what to do before handling, what to do when something has already happened, how to store it and how to dispose of it.

05 · Names in the regulation

1,3,5-triazine-2,4,6-triamine name in 23 EU languages

CLP Annex VI Part 3 is published in every language edition of the regulation, and the identification column is written out in each of them. Nothing below is translated by us: each line is the name as that edition prints it. Under Art. 18(2) the substance name from Annex VI is a lawful product identifier, so this is the wording to put on a label going to that market — and where the cell lists several designations, any one of them qualifies.

1,3,5-triazine-2,4,6-triamine carcinogenicity classification

IARC classification Group 2B — Possibly carcinogenic to humans
IARC monographs Volume 73: (1999) Some Chemicals that Cause Tumours of the Kidney or Urinary Bladder in Rodents and Some Other Substances; Volume 119: (2019) Some Chemicals That Cause Tumours of the Urinary Tract in Rodents

Under the conditions of this bioassay, melamine was carcinogenic for male F344/N rats, causing transitional-cell carcinomas in the urinary bladder. With one exception, urinary bladder stones were observed in male rats that had transitional-cell carcinomas. Melamine was not carcinogenic for female F344/N rats or for B6C3F1 mice of either sex.

Cancer Classification: Group D Not Classifiable as to Human Carcinogenicity

Source: Hazardous Substances Data Bank (HSDB)

Evaluation: There is inadequate evidence in humans for the carcinogenicity of melamine. There is sufficient evidence in experimental animals for the carcinogenicity of melamine under conditions in which it produces bladder calculi. Overall evaluation: In making the overall evaluation, the Working Group noted that a non-DNA reactive mechanism by which melamine produced urinary bladder tumors in male rats occurred only under conditions in which calculi were produced. Melamine is not classifiable as to its carcinogenicity to humans (Group 3).

Source: Hazardous Substances Data Bank (HSDB)

An IARC group and a CLP classification answer different questions. IARC judges whether the evidence for cancer in humans is strong enough; CLP Annex VI is the legally binding EU classification. A substance can carry one and not the other.
