Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

- Endpoint:
- oxidising liquids
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.21 (Oxidising Properties (Liquids))

- Duration of test (contact time):
- 10 min
- Key result
- Sample tested:
- test mixture 1:1
- Remarks:
- Test item/cellulose
- Parameter:
- mean pressure rise time
- Result:
- 23.16 s
- Sample tested:
- reference mixture 1: 1
- Remarks:
- Reference mixture= 65 % w/w aqueous nitric acid/ cellulose
- Parameter:
- mean pressure rise time
- Result:
- 7.7 s
- Interpretation of results:
- other: Not classified based on CLP criteria.
- Remarks:
- No oxidising properties
- Conclusions:
- OS-1600 was found to be non-oxidising.
- Executive summary:
A study was performed to determine the oxidising properties of OS-1600 in accordance with EU Method A.21.The mean pressure rise time for the reference mixture (1:1 w/w mixture of 65% w/w aqueous nitric acid and cellulose) was 7.7 seconds, while that for the test substance mixtures (1:1 w/w mixture of the test substance and cellulose) was 23.2 seconds. Since the time for the test substance mixture was much greater than that for the reference mixture, the test substance was considered to be a non-oxidiser.
- Endpoint:
- oxidising liquids
- Data waiving:
- other justification
- Justification for data waiving:
- the study does not need to be conducted because there are no chemical groups present in the molecule which are associated with oxidising properties and hence, the classification procedure does not need to be applied

Description of key information
OS-1600 was found to be non-oxidising.
Key value for chemical safety assessment
- Oxidising properties:
- no
Additional information
Data waiving (other justification): Test substance does not contain any chemical groups that will cause or contribute to the combustion of other material. Oxime group is not an oxidizing agent.
Key study: A study was performed to determine the oxidising properties of OS-1600 in accordance with EU Method A.21.The mean pressure rise time for the reference mixture was 7.7 seconds, while that for the test substance mixtures was 23.2 seconds. Since the time for the test substance mixture was much greater than that for the reference mixture, the test substance was considered to be a non-oxidiser.
Justification for classification or non-classification
Based on the available data, the test substance was determined to be non-oxidised and therefore, it is not classified in accordance with CLP Regulation (EC) no. 1272/2008.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
