Endpoint conclusion
- Endpoint conclusion:
- no adverse effect observed
- Dose descriptor:
- LD50
- Value:
- 2 000 mg/kg bw
Acute toxicity: via inhalation route
Link to relevant study records
- Endpoint:
- acute toxicity: inhalation
- Data waiving:
- study scientifically not necessary / other information available
- Justification for data waiving:
- the study does not need to be conducted because exposure of humans via inhalation is not likely taking into account the vapour pressure of the substance and/or the possibility of exposure to aerosols, particles or droplets of an inhalable size
- Justification for type of information:
- JUSTIFICATION FOR DATA WAIVING
According to the §8.5.2, column 2 of the annex VIII of REACh, testing is not appropriate for inhalation route since dermal exposure to the substance is more likely and acute toxicity data by dermal route is provided. - Reason / purpose for cross-reference:

Additional information
Justification for classification or non-classification
No adverse effect is observed at the highest dose tested (2000 mg/ kg body weight for oral and dermal routes), consequently no classification is needed. Nevertheless, existing harmonised classification (Index Number 607-007-00-3) for “salts of oxalic acid with the exception of those specified elsewhere in this Annex” should apply. Consequently, the substance is classified as Acute Tox. 4 (H302) for oral route and Acute Tox. 4 (H312) for dermal route.
