Safety Data Sheet
Getting an SDS for BBP
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 BBP 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
BBP precautionary statements
CLP Annex VI assigns 3 precautionary statements to BBP. 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.
Disposal
What has to happen to the contents and the empty container.

05 · Names in the regulation
BBP 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.

BBP health hazards and exposure limits
BBP carcinogenicity classification
Under the conditions of this 2-year feed study, there was some evidence of carcinogenic activity of butyl benzyl phthalate in male F344/N rats based on the increased incidences of pancreatic acinar cell adenoma and of acinar cell adenoma or carcinoma (combined). There was equivocal evidence of carcinogenic activity of butyl benzyl phthalate in female 344/N rats based on the marginally increased incidences of pancreatic acinar cell adenoma and of transitional epithelial papilloma of the urinary bladder.
Source: US National Toxicology Program · TR-458: Toxicology and Carcinogenesis Studies of Butyl Benzyl Phthalate (CASRN 85-68-7) in F344 Rats (Feed Studies) (1997 )
CLASSIFICATION: C; possible human carcinogen. BASIS FOR CLASSIFICATION: Based on statistically significant increase in mononuclear cell leukemia in female rats; the response in male rats was inconclusive and there was no such response in mice. HUMAN CARCINOGENICITY DATA: None. ANIMAL CARCINOGENICITY DATA: Limited.
Source: Hazardous Substances Data Bank (HSDB)
Evaluation: There is inadequate evidence in humans for the carcinogenicity of butyl benzyl phthalate. There is limited evidence in experimental animals for the carcinogenicity of butyl benzyl phthalate. Overall evaluation: Butyl benzyl phthalate is not classifiable as to its carcinogenicity to humans (Group 3).

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.

BBP reactivity
BUTYL BENZYL 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. Can generate electrostatic charges. [Handling Chemicals Safely 1980. p. 250].

11 · Questions
BBP — frequently asked questions
What is the CAS number of BBP?

The molecular formula of BBP is C19H20O4 and its molecular weight is 312.4 g/mol.
What does a BBP label have to show?
Under CLP Annex VI the label for BBP carries the pictograms Health hazard and Environment and the signal word is Danger.
Is BBP flammable?
CLP Annex VI assigns BBP 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 198.89 °C (390 °F) (HSDB).
Is BBP a carcinogen?
CLP Annex VI records no harmonised carcinogenicity classification for BBP. 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 boiling point of BBP?
The boiling point reported for BBP is 370 °C (698 °F) (HSDB).
What is the melting point of BBP?
The melting point reported for BBP is -35 °C (-31 °F) (HSDB).
How should BBP be stored?
Keep container tightly closed in a dry and well-ventilated place. Containers which are opened must be carefully resealed and kept upright to prevent leakage. Storage class (TRGS 510): Non-combustible, acute toxic Cat.3 / toxic hazardous materials or hazardous materials causing chronic effects (Hazardous Substances Data Bank (HSDB))
