Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Administrative data

oxidising solids
Type of information:
Adequacy of study:
weight of evidence
Study period:
March 2019
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
results derived from a valid (Q)SAR model and falling into its applicability domain, with adequate and reliable documentation / justification
Justification for type of information:
The purpose of this assessment is to evaluate the propensity of the test item to be potentially oxidising based on the chemical structure, and associated oxygen balance.
Oxygen balance should be used in conjunction with an evaluation of the molecular structrure for indicate chemical groups known to possess the potential to cause oxidisation.

Materials and methods

Test guideline

Principles of method if other than guideline:
QSAR evaluation

A substance may have oxidizing properties when:
the electronegative atoms which are present constitute a high proportion of the molecule and are bound to elements in a high oxidation state;
the electronegative atoms are bonded to each other or to other electronegative elements such as iodine, nitrogen, sulphur or phosphorus.
Compounds which have no highly electronegative atom - oxygen, fluorine, chlorine, bromine - are not likely to possess oxidizing properties. Similarly, where these elements are present but the atoms are only bonded to carbon and/or hydrogen, the oxdizing properties are unlikely.

For organic substances only, an oxygen balance (OB) calculation may be useful as a criteria combined with an eximation of the chemical structure as a means of predicting oxidizing properties. The oxygen balance is calculated from the empirical formula of a coumpound in percentage of oxygen required for complete conversion of carbon dioxide, hydrogen to water, and metal to metal oxide.

Applicant's summary and conclusion

Interpretation of results:
GHS criteria not met
Based on the information and review of the substance, the substance is deemed not to be potentially oxidising.
Executive summary:

The structure has an oxygen balance of <-200 and the chemical structure contains no alerts for oxidising potential.

Therefore on this basis, the substance is predicited to be not oxidising.
