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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
Additional information
Toxicity to soil macroorganisms except arthropods:
The lethal concentration (LC50) value of difluoroacetic acid on earthworm for a period of 14 days is found to be 2760.220 mg/L and hence it can be inferred that the chemical is non-toxic to soil macroorganisms.
Toxicity to terrestrial arthropods:
The LD50 value of difluoroacetic acid to soil arthropoda (Apis mellifera) in a 48 h study was estimated to be 70 ug/org .
Toxicity to terrestrial plants:
The effective concentration (EC50) value of difluoroacetic acid to plant (Lactuca sativa) in a 72hr study was estimated to be 1509.12 mg/L based on the effect on germination.
Toxicity to soil microorganisms:
The tests of the toxicity of difluoroacetic acid to soil microorganisms are considered to be unnecessary. Since
a) difluoroacetic acid is readily biodegradable
b) It is not applied directly to soil and
c) the substance is not expected to be transferred indirectly to soil in significant quantity via disposal of STP sludges or aerial deposition
d) Also the exposure of soil microorganisms to difluoroacetic acid is unlikely to occur.
Consequently tests of the toxicity of difluoroacetic acid to soil microorganisms are considered to be unnecessary.
Toxicity to birds:
No information on toxicity to birds available. Toxicity to birds is not a standard information requirement in Annex IX. Moreover, as the substance is not toxic to mammals (not classified for toxicity) no further toxicity testing on birds is proposed.
Toxicity to other above-ground organisms:
No experimental data in addition to those presented under CSR Chapter 5 is available. This is not a standard information requirement for environment in REACH.
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.
