Hazard class Category From code Pictogram
Carcinogenicity GHS chapter 3.6 Category 1A or 1B H350 GHS08

Where two values are shown with “or”, the hazard statement is shared by more than one category or by more than one class, and the code alone does not say which. H272, for example, belongs to oxidising liquids and to oxidising solids — the physical state decides. The binding answer for a specific entry is in the CLP Annex VI table itself.

Safety Data Sheet

Getting an SDS for 2,2'-(nitrosoimino)bisetha…

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 2,2'-(nitrosoimino)bis… 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

2,2'-(nitrosoimino)bisethanol precautionary statements

CLP Annex VI assigns 4 precautionary statements to 2,2'-(nitrosoimino)bisetha…. 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.

Response

What to do once exposure, spillage or fire has already happened.

05 · Names in the regulation

2,2'-(nitrosoimino)bisethanol 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.

2,2'-(nitrosoimino)bisethanol carcinogenicity classification

IARC classification Group 2B — Possibly carcinogenic to humans
IARC monographs Volume 17: (1978) Some N-Nitroso Compounds; Volume 77: (2000) Some Industrial Chemicals

CLASSIFICATION: B2; probable human carcinogen. BASIS FOR CLASSIFICATION: Increased incidence of liver tumors and tumors at other sites in three strains of rats and in hamsters. HUMAN CARCINOGENICITY DATA: Inadequate.

Source: Hazardous Substances Data Bank (HSDB)

No data are available in humans. Sufficient evidence of carcinogenicity in animals. OVERALL EVALUATION: Group 2B: The agent is possibly carcinogenic to humans.

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.
