Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Details on results:
The results are expressed in terms of nominal concentrations at 0 and 48 hours. The test item instantly hydrolyses to 1-Butanol and methane phosphinic acid in water in a ration of 48.1 % to 51.9 %. Analysis was carried out on 1-Butanol by GC analysis and FID detection. Effective concentrations correspond to 109.1% of the theoretical amount of 1-Butanol at 0 hours, and to 101.5% of the theoretical amount of 1-Butanol at 48 hours, respectively.

Applicant's summary and conclusion

Validity criteria fulfilled:
yes
Conclusions:
No toxic effects against daphnia were observed at a limit test concentration of 100 mg/L.
