- Details on test solutions:
- PREPARATION AND APPLICATION OF TEST SOLUTION (especially for difficult test substances)
- Method: Water accommodated fraction (WAF) of the test substance were prepared according to OECD 23. Fresh test solutions were prepared at 0 and 24 hours. The test substance was homogenized by shaking the container before removal for weighing. The stock solutions were prepared by weighing the test substance on a glass coverslip then adding this to 1L of test medium in a 2 L glass flask. The stock solutions were shaken for approximately 10 min at 20 ± 2 °C.
- Differential loading: yes
- Evidence of undissolved material (e.g. precipitate, surface film, etc): The test groups 22 - 100 mg/L appeared turbid after preparation. Since the test substance was homogenously dispersed in the test medium, no attempt was made to separate any potentially undissolved components. The daphnids were exposed to the entire loaded mass of test substance. - Test organisms (species):

Therefore, this study is informative for evaluation of the environmental fate and toxicity of the target substance, Reaction products of furan-2,5-dione and octadec-1-ene (known here as n-ODSA EC 701-338-8; no CASRN available), and it is adequate for classification and risk assessment.

- Specific details on test material used for the study:
- 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.

Description of key information
The key study was a semi-static acute daphnid toxicity test on the freshwater invertebrate, Daphnia magna, by read-across from an analogue substance.
Key value for chemical safety assessment
Fresh water invertebrates
Fresh water invertebrates
- Effect concentration:
- 36.3 mg/L
Additional information
The substance was shown to exhibit toxicity to the freshwater invertebrate Daphnia magna, by read-across based on a chemical category. The 48-h EL0 and EL50 values reported from the semi-static and static tests were 4.6 mg/L and 36.3 mg/L, respectively, based on loading rates.
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, and also known as PentasizeTM68, AS 1100TMand AS 1000TM), 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.
