Safety Data Sheet

Getting an SDS for Trisodium Nitrilotriacetat…

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 Trisodium Nitrilotriac… 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

Trisodium Nitrilotriacetate precautionary statements

CLP Annex VI assigns 12 precautionary statements to Trisodium Nitrilotriacetat…. 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

Trisodium Nitrilotriacetate 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.

Trisodium Nitrilotriacetate carcinogenicity classification

Evaluation: There is inadequate evidence in humans for the carcinogenicity of nitrilotriacetic acid and its salts. There is sufficient evidence in experimental animals for the carcinogenicity of nitrilotriacetic acid and its sodium salts. Overall evaluation: Nitrilotriacetic acid and its salts are possibly carcinogenic in humans (Group 2B). /Nitrilotriacetic acid and its salts/

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.
