Test material

Constituent 1
Chemical structure
Reference substance name:
Methyl formate
EC Number:
203-481-7
EC Name:
Methyl formate
Cas Number:
107-31-3
Molecular formula:
C₂H₄O₂
IUPAC Name:
methyl formate
Details on test material:
parasiticide, evidently containing methyl formate

Method

Type of population:
general
Subjects:
- Number of subjects exposed: 1
- Age: 19 months
Ethical approval:
not applicable
Remarks:
clinical case report
Route of exposure:
dermal
Reason of exposure:
intentional
Exposure assessment:
not specified
Details on exposure:
A fatal case of methyl formate poisoning in a 19-months old child was reported whose scalp had been treated with a parasiticide, evidently containing methyl formate, and subsequently covered for 20 min with a rubber cap.
Examinations:
Post mortem determination of methyl formate in brain and liver.

Results and discussion

Clinical signs:
 When the cap was removed after 20 minutes, the child collapsed, became cyanotic, and breathed slowly.
Results of examinations:
Methyl formate was found to be present in the brain. After hydrolysis to methanol, the methyl formate tissue burden was calculated to be 236 mg/kg in brain and 220 mg/kg in liver.
Effectivity of medical treatment:
No effective treatment
Outcome of incidence:
The child died from cardiac arrest. Brain, lings, liver, kidneys, and spleen were found highly congested.

Applicant's summary and conclusion

Executive summary:

Methyl formate may be dermally absorbed.
