Safety Data Sheet
Getting an SDS for Dihexyl phthalate
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 Dihexyl phthalate 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
Dihexyl phthalate precautionary statements
CLP Annex VI assigns 4 precautionary statements to Dihexyl phthalate. 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.
Prevention
What to do before and during handling so the hazard never happens.
Response
What to do once exposure, spillage or fire has already happened.

05 · Names in the regulation
Dihexyl phthalate 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.

Dihexyl phthalate reactivity
DI-N-HEXYL PHTHALATE is an ester. Esters react with acids to liberate heat along with alcohols and acids. Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products. Heat is also generated by the interaction of esters with caustic solutions. Flammable hydrogen is generated by mixing esters with alkali metals and hydrides. This compound can react with oxidizing materials and strong alkaline materials. (NTP, 1992)

What is the chemical formula of Dihexyl phthalate?
The molecular formula of Dihexyl phthalate is C20H30O4 and its molecular weight is 334.4 g/mol.
What does a Dihexyl phthalate label have to show?
Under CLP Annex VI the label for Dihexyl phthalate carries the pictogram Health hazard and the signal word is Danger.
Is Dihexyl phthalate flammable?
CLP Annex VI assigns Dihexyl phthalate 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 193.89 °C (381 °F) (HSDB).
Is Dihexyl phthalate a carcinogen?
CLP Annex VI records no harmonised carcinogenicity classification for Dihexyl phthalate. 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 Dihexyl phthalate?
The boiling point reported for Dihexyl phthalate is 350 °C (662 °F), at 735 mmHg (CAMEO).
What is the melting point of Dihexyl phthalate?
The melting point reported for Dihexyl phthalate is -58 °C (-72.4 °F) (HSDB).
