Endpoint:
short-term toxicity to aquatic invertebrates
Type of information:
experimental study
Adequacy of study:
key study
Study period:
no data
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Justification for type of information:
The study was performed according to a valid guideline without any deviations and was conducted under GLP conditions. Furthermore, the data were submitted by another legal entity, under Directive 67/548/EEC, at least 12 years previously. The registrant has been granted permission to use the information, which has been extracted from the ECHA databases, for REACH registration purposes. No full information related to the experimental result are available but these deficiencies do not affect the quality of the relevant results.

Validity criteria fulfilled:
not specified
Conclusions:
Under the conditions of the study the 48-hour EC50 of the test material was determined to be > 0.27 mg/L . The result suggests that the test material is not toxic up to the limit of solubility.
Executive summary:

An experimental test was performed under GLP contitions and according to EU Method C.2.

Under the conditions of the study the 48-hour EC50 of the test material was determined to be > 0.27 mg/L . The result suggests that the test material is not toxic up to the limit of solubility.

Description of key information

 the 48-hour EC50 of the test material was determined to be > 0.27 mg/L in an experimental study on aquatic invertebrates, under GLP conditions.

Key value for chemical safety assessment

EC50/LC50 for freshwater invertebrates:
0.27 mg/L
