Administrative data
Link to relevant study record(s)
- Endpoint:
- oxidising solids
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2017-09-13 to 2018-01-31
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- UN Manual of Tests and Criteria: Test O.1 (Test for oxidizing solids)
- Version / remarks:
- 2017
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Contact with:
- powdered cellulose
- Duration of test (contact time):
- 3 min
- Key result
- Sample tested:
- 1:1 sample-to-cellulose ratio
- Parameter:
- mean burning time
- Result:
- > 180 s
- Remarks on result:
- flaming
- Remarks:
- The test item showed a slight burning
- Key result
- Sample tested:
- 4:1 sample-to-cellulose ratio
- Parameter:
- mean burning time
- Result:
- > 180 s
- Remarks on result:
- flaming
- Remarks:
- The test item showed a slight burning
- Key result
- Sample tested:
- reference: 3:7 mixture potassium bromate + cellulose
- Parameter:
- mean burning time
- Result:
- 116 s
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The burning time of the mixtures of the test item with cellulose (4:1 and 1:1) was higher than the burning time of the reference mixture of potassium bromate and cellulose (3:7). Due to the tests results the test item does not have to be classified as oxidizing solid.
This test item has to be classified as follows:
UN Transport Regulation: The test item does not have to be classified as oxidizing solid in Division 5.1 according to the UN Transport Regulation.
GHS and EC 1272/2008 (CLP Regulation), Annex 1: 2.14: The test item does not have to be classified as oxidizing solid according to GHS and EC 1272/2008 (CLP Regulation) Annex 1: 2.14.
Reference
Description of key information
- non oxidising (UN Test O.1, GLP)
Key value for chemical safety assessment
- Oxidising properties:
- non oxidising
Additional information
The burning time of the mixtures of the test item with cellulose (4:1 and 1:1) was higher than the burning time of the reference mixture of potassium bromate and cellulose (3:7). Due to the tests results the test item does not have to be classified as oxidizing solid.
Justification for classification or non-classification
Based on the available data, tetrahydrofolic acid does not meet the classification criteria for oxidising solids according to Regulation (EC) No. 1272/2008 (CLP and the Globally Harmonized System of Classification of Chemicals (GHS).
