Principles of method if other than guideline:

Using an automatic Pensky-Martens closed cup, the sample is heated and stirred and an ignitor is dipped into the head space at intervales to test for a flash.

GLP compliance:

no

Type of method:

closed cup

Flash point apparatus:

Pensky-Martens apparatus

Dynamic viscosity of test material:

Not available/not technically feasible.

Specific details on test material used for the study:

Waxy solid, warmed and melted for this test.
Batch 45623, free olefin content 3.6%, manufacture date 11 Sept. 2015.
Batch 45637, free olefin content 4.16%, tanker blend sampled 10 Sept. 2015
As a result of increasingly rigorous criteria being applied to the analysis of commercial material used in physical property/toxicity testing, the identity of the material has been modified to reveal a more accurate and precise depiction of the commercial substance. This enhancement is reflected in changes in chemical identifiers such as EC and/or CAS numbers from those noted in earlier versions of data records or in study reports.

Key result

Flash point:

> 150 °C

Atm. press.:

101.3 kPa

Remarks on result:

other: assume standard atmospheric pressure

The samples were tested once each. No flash point was detected up to 150 ^oC.

Interpretation of results:

GHS criteria not met

Conclusions:

The flash point of n-ODSA EC 701-338-8 is above 150 °C. No classification for flammability is indicated according to Regulation EC No. 1272/2008.

Description of key information

> 150 °C

Key value for chemical safety assessment

Flash point at 101 325 Pa:

150 °C

Additional information

The measured flash point of n-octadecenyl succinic anhydride (n-ODSA) is greater than 150°C.

This is consistent with a flash point reported for a structural analogue (C15 -20 Succinic Anhydride, 2,5-furandione, dihydro-, mono-C15- 20-alkenyl derivatives (CAS 68784-12-3)), which is experimentally determined to be 206.0^oC.

This information is from the substance 2,5-furandione, dihydro-,mono-C15-20-alkenylderivatives (CAS 68784-12-3, a mixture of a hexadecenyl- and octadecenyl succinic anhydrides, an analogue used for the assessment of several endpoints through read-across. The hypothesis for read-across between the substance being registered (Reaction products of furan-2,5-dione and octadec-1-ene; known here as n-ODSA EC 701-338-8; no CASRN available), and the analogue substance is a common functional group: a 2,5-furandione, dihydro- structure, also known as a succinic anhydride, to which is attached a long-chain monounsaturated olefin. In the environment, the anhydride moiety is quickly hydrolysed to form a dioic acid.  When the substance to be registered and the analogue substance are compared, changes in the purity of the starting olefin stock, or small differences in the length (between sixteen and twenty) or arrangement (linear or branched) of the carbon chain are not anticipated to significantly affect the environmental fate properties or the toxicity of the substances. For each endpoint study based upon read-across, the analogue approach is substantiated by an evaluation provided in the Analogue Approach Report Format (AARF) attached to the endpoint study summary file. The AARF allows the read-across information to fulfil the information requirements of the REACH Annexes VII-X, to be the basis for classification and labelling decisions, and for risk assessment.
