- Conclusions:
- SH-0850 has no structural alerts for oxidising potential, nor is the oxygen balance indicative of the test item being potentially oxidising.
The lack of structural alerts and the oxygen balance indicates that there is no concern for oxidising properties associated with this substance. - Executive summary:
Before performing a test to determine a test item's oxidizing properties, it is important to check that this test is applicable to the test item.
A test item 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, then oxidizing properties are unlikely.
As the ability to predict the reactivity of chemicals compounds from their structure is somewhat limited, the best approach is by analogy with existing compounds whom are known to be oxidisers. As such, there is a known list of oxidizing compounds and reactive groups which increase the oxidizing power of a molecule. However, this list is not exhaustive. If the test item meets one of the above criteria, the lack of any reactive group may not be sufficient to justify not performing the EU Method A.17 (Oxidising Properties (Solids)) test.
For organic test items only, an Oxygen Balance (OB) calculation may be useful as a criteria combined with an examination of the chemical structure as a means of predicting oxidizing properties. The oxygen balance is calculated from the empirical formula of a compound in percentage of oxygen required for complete conversion of carbon to carbon dioxide, hydrogen to water, and metal to metal oxide.
SH-0850 has no structural alerts for oxidising potential, nor is the oxygen balance indicative of the test item being potentially oxidising.
The lack of structural alerts and the oxygen balance indicates that there is no concern for oxidising properties associated with this substance.
The regulatory position (specifically the MEP Order No. 7 - "China REACH" and EC Regulation No. 1907/2006 on Registration, Evaluation, Authorisation and Restriction of Chemicals - "REACH") with regards to oxidising properties is that a study does not need to be conducted if:
• the test item is explosive; or
• the test item is highly flammable; or
• the test item is an organic peroxide (whose category is verified by testing); or
• the test item contains no highly electronegative atoms; or
• the test item is incapable of reacting exothermically with combustible materials
A full test does not need to be conducted for solids if any preliminary evaluation clearly indicates that the test item has oxidising properties.
Note that as there is no test method to determine the oxidising properties of gaseous mixtures, the evaluation of these properties must be realised by an estimation method based on the comparison of the oxidising potential of gases in a mixture with that of the oxidising potential of oxygen in air.
