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:
UN Manual of Tests and Criteria: Test O.1 (Test for oxidizing solids)
Version / remarks:
2017
Deviations:
no
GLP compliance:
yes (incl. certificate)
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.

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).
