Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Link to relevant study record(s)
- Endpoint:
- oxidising solids
- Type of information:
- read-across from supporting substance (structural analogue or surrogate)
- Adequacy of study:
- key study
- Justification for type of information:
- See Read across justification in Chapter 13
- Reason / purpose for cross-reference:
- read-across source
- GLP compliance:
- not specified
- Sample tested:
- other: not specifies (migrated information) Pre-test Potassium bromate/ Cellulose (1:1)
- Parameter:
- other: Pre-test Potassium bromate / Cellulose (1:1)
- Result:
- 116 s
- Sample tested:
- other: not specifies (migrated information) Pre-test Potassium bromate/ Cellulose (4:1)
- Parameter:
- other: Pre-test Potassium bromate/ Cellulose (4:1)
- Result:
- 58 s
- Sample tested:
- other: not specifies (migrated information) Pre-test Test item / Cellulose (4:1)
- Parameter:
- other: Pre-test Test item / Cellulose (4:1)
- Result:
- 73 s
- Sample tested:
- other: not specifies (migrated information) Pre-test Test item / Cellulose (1:1)
- Parameter:
- other: Pre-test Test item / Cellulose (1:1)
- Result:
- 156 s
- Interpretation of results:
- other: no oxidising properties
- Conclusions:
- The test item does not have to be classified as oxidizing solid according to GHS and EC 1272/2008 (CLP-Guideline) Annex 1: 2.14.
- Executive summary:
The mean burning times of the test item-to-Kieselguhr ratio 4:1 (57s) and 1:1 (94 s) are lower than the mean burning times of a 4:1 and 1:1 mixture of test item-to-Cellulose (73 s and 156 s, respectively). This shows that the test results with Cellulose are false positive, as the pure test item itself is flammable in mixtures with Kieselguhr. Due to this the test item does not have to be classified as oxidizing solid.
- Endpoint:
- oxidising solids
- Type of information:
- experimental study
- Adequacy of study:

- Reliability:
- 2 (reliable with restrictions)
- Justification for type of information:
- Read-across to C.I. Pigment Orange 5 which has no oxidising properties even though it has two nitro-groups in the molecule
- Qualifier:
- according to guideline
- Guideline:
- other: UN Test O.1 - Oxidizing solids
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.17 (Oxidising Properties (Solids))
- GLP compliance:
