Safety Data Sheet

Getting an SDS for Sodium 2-biphenylate

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 Sodium 2-biphenylate 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

Sodium 2-biphenylate precautionary statements

CLP Annex VI assigns 16 precautionary statements to Sodium 2-biphenylate. 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

Sodium 2-biphenylate 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.

Sodium 2-biphenylate 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

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.

Sodium 2-biphenylate properties

Every value is shown with the conditions it was measured under and the source it came from. Where sources disagree, all values are listed rather than one being picked — the difference is usually a different form of the substance, not an error.

09 · Handling and storage

Sodium 2-biphenylate storage and handling

Sodium 2-biphenylate reactivity

Salts, basic, such as SODIUM O-PHENYLPHENOXIDE are generally soluble in water. The resulting solutions contain moderate concentrations of hydroxide ions and have pH's greater than 7.0. They react as bases to neutralize acids. These neutralizations generate heat, but less or far less than is generated by neutralization of the bases in reactivity group 10 (Bases) and the neutralization of amines. They usually do not react as either oxidizing agents or reducing agents but such behavior is not impossible.

10 · Questions

Sodium 2-biphenylate — frequently asked questions

What is the CAS number of Sodium 2-biphenylate?

The CAS number of Sodium 2-biphenylate is 132-27-4. Its EC number is 205-055-6.

What does a Sodium 2-biphenylate label have to show?

Under CLP Annex VI the label for Sodium 2-biphenylate carries the pictograms Corrosion, Exclamation mark and Environment and the signal word is Warning.

Is Sodium 2-biphenylate flammable?

CLP Annex VI assigns Sodium 2-biphenylate no flammability hazard class. That is not a statement that it cannot burn: the harmonised list only records the hazards that were assessed for it.

Is Sodium 2-biphenylate a carcinogen?

CLP Annex VI records no harmonised carcinogenicity classification for Sodium 2-biphenylate. 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 2B: possibly carcinogenic to humans.
