Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
other: GLP guideline study
Reason / purpose for cross-reference:
reference to same study
Qualifier:
according to guideline
Guideline:
other: UN-Test O.1: Test for oxidizing solids
Deviations:
no
GLP compliance:
yes (incl. QA statement)
Remarks:

Contact with:
powdered cellulose
Duration of test (contact time):
3 min
Sample tested:
test mixture (not specified)
Remarks:
migrated information
Parameter:
maximum burning rate
Result:
0 s
Remarks on result:
other: The mixtures of the test item with cellulose 4:1 showed no flaming or glowing combustion.
Sample tested:
test mixture (not specified)
Remarks:
migrated information
Parameter:
maximum burning rate
Result:
198 s
Remarks on result:
other: Mixture test item/cellulose of 1:1. The mean burning time of the mixture of the test item/cellulose 1:1 is 185 s.
Sample tested:
reference mixture (not specified)
Remarks:
migrated information
Parameter:
maximum burning rate
Result:
127 s
Remarks on result:
other: Mixture of potassium bromate/cellulose 3:7. Mean burning rate is 122 s.
Sample tested:
reference mixture (not specified)
Remarks:
migrated information
Parameter:
maximum burning rate
Result:
66 s
Remarks on result:
other: Mixture of potassium bromate/cellulose 2:3. Mean burning rate is 63 s.
Sample tested:
reference mixture (not specified)
Remarks:
migrated information
Parameter:
maximum burning rate
Result:
20 s
Remarks on result:
other: Mixture of potassium bromate/cellulose 3:2. Mean burning rate is 19 s.

Due to the fact that the mixtures of the test item with cellulose (4:1) showed no flaming or glowing combustion and the mixture of the test item with cellulose (1:1) have higher mean burning times compared to the reference mixture in the ratio 3:7,it is concluded that the test item has no oxidizing properties.

Interpretation of results:
other: no oxidising properties
Remarks:
Migrated information
Conclusions:
Zinc selenite has no oxidising properties. It does not meet the classification criteria for oxidizing properties in accordance with Regulation (EC) No. 1272/2008 on the classification, labelling and packaging of substances and mixtures (“CLP Regulation”) or in the sense of the UN Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria, Part III, section 34.4.1 (Test O.1).

Description of key information

Zinc selenite has no oxidising properties.

Key value for chemical safety assessment

Oxidising properties:
no

Additional information

The test data (GLP, OECD guideline conform) is reliable without restrictions.

Justification for classification or non-classification

Zinc selenite does not meet the classification criteria for oxidizing properties in accordance with Regulation (EC) No. 1272/2008 on the classification, labelling and packaging of substances and mixtures (“CLP Regulation”).
