Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

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.

Administrative data

Endpoint:
fish early-life stage toxicity
Type of information:
experimental study planned
Justification for type of information:
TESTING PROPOSAL ON VERTEBRATE ANIMALS

NON-CONFIDENTIAL NAME OF SUBSTANCE:
- Tetramethylammonium hydroxide (TMAH) / EC 200-882-9 / CAS 75-59-2

CONSIDERATIONS THAT THE GENERAL ADAPTATION POSSIBILITIES OF ANNEX XI OF THE REACH REGULATION ARE NOT ADEQUATE TO GENERATE THE NECESSARY INFORMATION:
- Available GLP studies: none available
- Available non-GLP studies: none available
- Historical human/control data: not applicable
- (Q)SAR: none available
- In vitro methods: none available
- Weight of evidence: none available
- Grouping and read-across: not applicable
- Substance-tailored exposure driven testing: not applicable
- Approaches in addition to above: not applicable

CONSIDERATIONS THAT THE SPECIFIC ADAPTATION POSSIBILITIES OF ANNEXES VI TO X (AND COLUMN 2 THEREOF) OF THE REACH REGULATION ARE NOT ADEQUATE TO GENERATE THE NECESSARY INFORMATION:
- According to data point 9.1.6 and taking into account the Board of Appeal Decision in case A-011-208, data on the long-term toxicity to fish is a standard data requirement which cannot be waived and thus should be submitted. Since this information was not already provided as part of Annex VIII requirements, the data needs to be generated and submitted for the current REACH Registration above 1000 tonnes (Annex X).

FURTHER INFORMATION ON TESTING PROPOSAL IN ADDITION TO INFORMATION PROVIDED IN THE MATERIALS AND METHODS SECTION:
- The study will be performed according to OECD TG 210 (2013, the most recent version available) and GLP principles.
