Safety Data Sheet

Getting an SDS for Decanoic Acid

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 Decanoic Acid 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

Decanoic Acid precautionary statements

CLP Annex VI assigns 11 precautionary statements to Decanoic Acid. 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

Decanoic Acid 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.

All 23 language editions of Annex VI carry this entry. Irish is the twenty-fourth official EU language and has no line here for a different reason: no consolidated CLP text has ever been published in Irish, so there is no Irish edition of Annex VI to quote a name from.

Decanoic Acid storage and handling

Decanoic Acid storage conditions

Safe Storage of Pesticides. Always store pesticides in their original containers, complete with labels that list ingredients, directions for use, and first aid steps in case of accidental poisoning. Never store pesticides in cabinets with or near food, animal feed, or medical supplies. Do not store pesticides in places where flooding is possible or in places where they might spill or leak into wells, drains, ground water, or surface water. /Residential uses/

11 · Questions

Decanoic Acid — frequently asked questions

What is the CAS number of Decanoic Acid?

The CAS number of Decanoic Acid is 334-48-5. Its EC number is 206-376-4.

What does a Decanoic Acid label have to show?

Under CLP Annex VI the label for Decanoic Acid carries the pictogram Exclamation mark and the signal word is Warning.

Is Decanoic Acid flammable?

CLP Annex VI assigns Decanoic Acid 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. The flash point reported for it is 112.78 °C (235 °F) (CAMEO).

Is Decanoic Acid a carcinogen?

CLP Annex VI records no harmonised carcinogenicity classification for Decanoic Acid. 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.

What is the boiling point of Decanoic Acid?

The boiling point reported for Decanoic Acid is 268.7 °C (515.7 °F) (HSDB).

What is the melting point of Decanoic Acid?

The melting point reported for Decanoic Acid is 31.5 °C (88.7 °F) (HSDB).

How should Decanoic Acid be stored?

Safe Storage of Pesticides. Always store pesticides in their original containers, complete with labels that list ingredients, directions for use, and first aid steps in case of accidental poisoning. Never store pesticides in cabinets with or near food, animal feed, or medical supplies. Do not store pesticides in places where flooding is possible or in places where they might spill or leak into wells, drains, ground water, or surface water. /Residential uses/ (Hazardous Substances Data Bank (HSDB))
