Results and discussion
Main ADME resultsopen allclose all
- Type:
- absorption
- Results:
- Ethyl formate is readily absorbed into the blood via the alveoli of the respiratory system. It is also reported to be absorbed from the gastrointestinal tract and slightly through the skin
- Type:
- distribution
- Results:
- Distributed to the liver where it is metabolized.
- Type:
- metabolism
- Results:
- With moisture, ethyl formate readily hydrolyses into formic acid and ethanol. Formic acid is metabolised further by the tetrahydrofolate system to CO2. Ethanol is metabolised further to acetaldehyde, acetic acid,
Metabolite characterisation studies
- Metabolites identified:
- yes
- Details on metabolites:
- Enzymatic hydrolysis occurs. With moisture, ethyl formate readily hydrolyses into formic acid and ethanol. Formic acid is metabolised further by
the tetrahydrofolate system to CO2. Ethanol is metabolised further in the liver to acetaldehyde, acetic acid, and, finally, CO2, by alcohol dehydrogenase, aldehyde dehydrogenase, and the tricarbonic acid cycle, respectively.
Metabolites - formic acid, & ethanol. Ethanol is metabolised further in the liver to acetaldehyde, acetic acid, and, finally, CO2.
Any other information on results incl. tables
From the data available for the absorption, metabolism and excretion of the chemical ethyl formate and the maximum allowable concentration of 100 ppm (300 mg/m3), 8-hour TWA, it can be concluded that the chemical is likely to exhibit low bio-accumulation potential based on data reported in the reference.
Applicant's summary and conclusion
- Conclusions:
- Interpretation of results (migrated information): low bioaccumulation potential based on study results
From the data available for the absorption, metabolism and excretion of the chemical ethyl formate and the maximum allowable concentration of 100 ppm (300 mg/m3), 8-hour TWA, it can be concluded that the chemical is likely to exhibit low bio-accumulation potential based on data reported in the reference. - Executive summary:
Data available in the present report on absorption, metabolism and excretion of the chemical ethyl formate and the metabolites formic acid, & ethanol & ethanol being metabolised further in the liver to acetaldehyde, acetic acid, and, finally, CO2 indicate thatoverloading of the buffer capacity of the body and subsequently, a metabolic acidosis is not expected.Also, from the reported elimination rates of ethanol it can be seen thataccumulation of metabolites will not occur. Thusthe chemical is likely to exhibit low bio-accumulation potential based on data reported.
