- guideline study
- Qualifier:
- according to guideline
- Guideline:
- UN Manual of Tests and Criteria: Test O.1 (Test for oxidizing solids)
- Deviations:
- no
- GLP compliance:
- no
- Contact with:
- powdered cellulose
- Duration of test (contact time):
- 444 s
- Key result
- Sample tested:
- 1:1 sample-to-cellulose ratio
- Parameter:
- maximum burning rate
- Result:
- 444 s
- Key result
- Sample tested:
- 4:1 sample-to-cellulose ratio
- Parameter:
- maximum burning rate
- Result:
- 724 s
- Sample tested:
- reference: 3:2 mixture potassium bromate + cellulose
- Parameter:
- maximum burning rate
- Result:
- 21 s
- Sample tested:
- reference: 2:3 mixture potassium bromate + cellulose
- Parameter:
- maximum burning rate
- Result:
- 62 s
- Sample tested:
- reference: 3:7 mixture potassium bromate + cellulose
- Parameter:
- maximum burning rate
- Result:
- 127 s
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- Potassium hexadecyl hydrogen phosphate has no oxidising properties according to UN test O.1.
- Executive summary:
A study was conducted according to recommendations on the Transport of dangerous goods Manual of Test and Criteria Test O.1 which is recommended in the information and requirements for chemical safety assessment (IR/CSA) Chapter R.7a table R.7.1-9. The combustion time of a potassium hexadecyl hydrogen phosphate / Cellulose 1:1 mixture was determined to be 444s. The average combustion time of a KBrO3 / Cellulose 3:7 mixture was determined to be 127 s. The shortest combustion time of the potassium hexadecyl hydrogen phosphate / Cellulose mixture was higher than the reference time. Thus, potassium hexadecyl hydrogen phosphate was expected to have no oxidising properties.

Description of key information
Potassium hexadecyl hydrogen phosphate is not expected to have oxidising properties according to UN test O.1.
Key value for chemical safety assessment
- Oxidising properties:
- no
Additional information
A study was conducted according to recommendations on the Transport of dangerous goods Manual of Test and Criteria method O.1 which is recommended in the information and requirements for chemical safety assessment (IR/CSA) Chapter R.7a table R.7.1-9. The combustion time of a potassium hexadecyl hydrogen phosphate / Cellulose 1:1 mixture was determined to be 444s. The average combustion time of a KBrO3 / Cellulose 3:7 mixture was determined to be 127 s. The shortest combustion time of the potassium hexadecyl hydrogen phosphate / Cellulose mixture was higher than the reference time. Thus, potassium hexadecyl hydrogen phosphate was expected to have no oxidising properties.
Justification for classification or non-classification
Classification, Labelling, and Packaging Regulation (EC) No 1272/2008
Based on the chemical structure and taking into account the provisions laid down in Regulation (EC) No 1272/2008 (CLP), as amended for fourteenth time in Regulation (EC) 2020/217, and UN GHS Rev 8 (2019) the substance is not considered to be classified for oxidising properties.
