Description of key information
No effects up to the limit of water solubility for Brachydanio rerio (ISO 7346-1)
Key value for chemical safety assessment
Additional information
One fish toxicity study is available for 2,2-dimethyl-1,3-propanediyl dioleate (CAS No. 42222-50-4).
The key study conducted with 2,2-dimethyl-1,3-propanediyl dioleate (CAS No. 42222-50-4) was performed, according to ISO 7346-1, in a semi-static system, using Brachydanio rerio as test organism (Gode, 2008). The fish were exposed to the nominal test concentrations of 100, 300, 1000, 3000 and 10000 mg/L, during 96 hours. The test solutions were prepared as water accommodated fractions (WAF). No blank control was used in the test. However, as no mortalities were observed at any of the test concentrations, it can be concluded that 2,2- dimethyl-1,3 -propanediyl dioaleate is not acutely toxic to fish at concentrations≤10000 mg/L. An EC50 of > 10000 mg/L is reported. Taking into account that this test is not regarded as a standard OECD 202, but as a toxicity limit screening test, a Klimisch grade 2 is justifiable.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
