The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information

Additional information

With high probability the test substance shows no toxic effects to fish. Based on data for an structure analogue substance, the test substance has with high probability a low toxicity to aquatic organisms of the other two trophic levels (invertebrates, algae). The structure analogue substance was practically non-toxic to algal species tested. Over a longer period, the structure analogue substance was not toxic to the freshwater aquatic invertebrate tested (Daphnia magna) at test concentrations approximating the solubility limit of this compound (NOEC >= 0.0088 mg/L). However, higher test concentrations used in the tests resulted in physical immobilisation due to adherence of the test substance to the external body surfaces of the Daphnia. Physical immobilisation of 40 % or more of the test organisms occurred at analogue concentrations of 0.5 mg/L or greater.

Read across justification:

According to regulation (EC) No 1907/2006, Annex XI, paragraph 1.5., substances whose physicochemical, toxicological and ecotoxicological properties are likely to be similar or follow a regular pattern as a result of structural similarity may be considered as a group, or "category" of substances. Environmental effects or environmental fate may be predicted from data for reference substance(s) within the group by interpolation to other substances in the group (read-across approach).

The substance (EC No. 402 -860 -6) has an identical basic structure as the read across substance (EC No. 438 -600 -3). The only difference between the two substances are the carbon side chains which vary in length. EC No. 402 -860 -6 contains 8 C-atoms whereas EC No. 438 -600 -3 contains 12 C-atoms. The physical and chemical properties are very similar. Thus, it is acceptable to predict the aquatic toxicity from data of EC No. 402 -860 -6.
