Oxidising properties
Administrative data
Link to relevant study record(s)
- Endpoint:
- oxidising solids
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- From 05/02/2018 to 06/03/2018
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.17 (Oxidising Properties (Solids))
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Contact with:
- powdered cellulose
- Key result
- Sample tested:
- reference mixture as specified
- Remarks:
- Composition of 2:1 ratio (barium nitrate : powdered cellulose
- Parameter:
- preliminary test
- Result:
- 41 s
- Remarks on result:
- vigorous reaction in the preliminary test
- Remarks:
- Orange, sparkling flame
- Key result
- Sample tested:
- reference mixture as specified
- Remarks:
- Composition of 2:1 ratio (Test item : powdered Cellulose)
- Parameter:
- preliminary test
- Remarks on result:
- other: Orange flame which extinguished within 4 seconds
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The reaction for the Saccharomyces Cerevisiae, Lysate/ cellulose mixture was significantly slower than the reference mixture. It is clear, therefore, that the sample is not an oxidising solid.
- Executive summary:
The oxidizing properties of Saccharomyces cerevisiae has been tested according to EU Method A17 (solids) and the GLP.
After being dried at 105°C until constant weight and the particule size reduced to < 0.125 mm, the test item was mixed with cellulose in the proportion 2 of test substance to 1 of cellulose. This mixture forming a small cone was put in contact with a hot flame. The vigour and duration of the reaction was observed in comparison with the behaviour of the reference substance (barium nitrate) mixed with cellulose and subjected to the same conditions. The reaction for the Saccharomyces Cerevisiae, Lysate/ cellulose mixture was significantly slower than the reference mixture. It is clear, therefore, that the sample is not an oxidising solid.
This oxidizing properties study is classified as acceptable, and satisfies the guideline requirements of the EU method A17

Description of key information
The reaction for the test item / cellulose mixture was significantly slower than the reference mixture. It is clear, that Saccharomyces Cerevisiae, Lysate is not an oxidising solid.
Key value for chemical safety assessment
- Oxidising properties:
- non oxidising
Additional information
The sample has been tested according to EU Method A17 (solids) and the GLP.
After being dried at 105°C until constant weight and the particule size reduced to < 0.125 mm, the test item was mixed with cellulose in the proportion 2 of test substance to 1of cellulose. This mixture forming a small cone was put in contact with a hot flame. The vigour and duration of the reaction was observed in comparison with the behaviour of the reference substance (barium nitrat) mixed with cellulose and subjected to the same conditions. The reaction for the Saccharomyces Cerevisiae, Lysate/ cellulose mixture was significantly slower than the reference mixture. It is clear, therefore, that the sample is not an oxidising solid.
