Safety Data Sheet

Getting an SDS for Fenaminosulf

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 Fenaminosulf 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

Fenaminosulf precautionary statements

CLP Annex VI assigns 10 precautionary statements to Fenaminosulf. 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.

Disposal

05 · Names in the regulation

Fenaminosulf 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.

Fenaminosulf health hazards and exposure limits

Fenaminosulf carcinogenicity classification

IARC classification Group 3 — Not classifiable as to its carcinogenicity to humans
IARC monographs Volume 8: (1975) Some Aromatic Azo Compounds

Under the conditions of this bioassay, dietary administration of formulated fenaminosulf was not carcinogenic in either Fischer 344 rats or B6C3F1 mice.

Source: US National Toxicology Program · TR-101: Bioassay of Formulated Fenaminosulf for Possible Carcinogenicity (CASRN 140-56-7) (1978 )

Classification of carcinogenicity: 1) evidence in humans: No adequate data. 2) evidence in animals: Inadequate data. Overall summary evaluation of carcinogenic risk to humans is Group 3: The agent is not classifiable as to its carcinogenicity to humans. /From table/

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.

What does a Fenaminosulf label have to show?

Under CLP Annex VI the label for Fenaminosulf carries the pictogram Skull and crossbones and the signal word is Danger.

Is Fenaminosulf flammable?

Is Fenaminosulf a carcinogen?

CLP Annex VI records no harmonised carcinogenicity classification for Fenaminosulf. Annex VI is a list of agreed classifications, not a list of substances found safe, so this is an absence of a classification rather than a clean bill of health. IARC places it in Group 3: not classifiable as to its carcinogenicity to humans.

What is the melting point of Fenaminosulf?

The melting point reported for Fenaminosulf is 200 °C (392 °F), decomposes (CAMEO).
