Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Annex VIII of the REACH regulation mentions that the assessment of the toxicokinetic behaviour of the substance should be reported to the extent that can be derived from the relevant available information. From the search done for available data, it is reported that no known toxicity data is available for methyl trifluoroacetate.

The methanol hydrolytic half-life of methyl trifluoroacetate is less than 1 minute. Methanol and trifluoroacetic acid result from the reaction with water in the mucous membranes, upper respiratory tract, eyes and skin. Methanol is harmful and exposure to liquid or vapors may cause blindness or death. While the toxicity of trifluoroacetic acid is low, contact with the skin may cause burns. The acid diffuses into the affected tissue and destroys as it penetrates. Fumes may also be irritating. Wash any affected area for at least 15 minutes and treat as third degree burn even though appearance may not indicate severity of skin damage.

Thus, in the light of the above information, conducting a toxico-kinetic study for methyl trifluoroacetate seems scientifically unjustified.

Additional information

Thus, in the light of the above information, conducting a toxico-kinetic study for methyl trifluoroacetate seems scientifically unjustified. In addition, there is very low possibility of the chemical being ingested within the living system, except accidentally. If this occurs, there shall be no bioaccumulation due to injury to the internal organs.
