Administrative data

Endpoint:
oxidising solids
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
the study does not need to be conducted because the organic substance contains oxygen or halogen atoms which are chemically bonded only to carbon or hydrogen and hence, the classification procedure does not need to be applied
Justification for type of information:
JUSTIFICATION FOR DATA WAIVING
In accordance with column 2 of REACh Annex VII, the study does not need to be conducted if the substance is incapable of reacting exothermically with combustible materials, for example on the basis of the chemical structure. According to Regulation (EC) N°1272/2008 (CLP) criteria (Annex I §2.13.4./2.14.4., or as listed in the ECHA endpoint specific guidance on information requirements (R.7a, v6.0, July 2017, §R.7.1.13)), the constituents of the substance contain oxygen, but this element is chemically bonded only to carbon (especially not bonded to nitrogen or other oxygen).
In addition, technical issues are anticipated to conduct the tests related to Oxidizing properties of solids (UN Test O1) or Oxidizing properties of liquids (UN Test O2), due to the physical state of the substance. Indeed, several assays have been conducted on other very viscous / pasty natural complex substances (try to mix the substance as such with dried cellulose at room temperature and melted at 70°C) but it was not possible to prepare suitable homogenous cellulose/test item mixtures and the test on these substances were stated as unfeasible.
Then oxidising properties are unlikely, and the classification procedure shall not apply, no further testing is required.
