Adequacy of study:

key study

Study period:

26 July 2019

Reliability:

2 (reliable with restrictions)

Rationale for reliability incl. deficiencies:

other: An assessment was undertaken based on an examination of the molecular structure (functionality) of the substance

Qualifier:

no guideline required

Principles of method if other than guideline:

An assessment was performed to establish the oxidising potential of Thermal cracking oil from blends of rubber, fuel oils and paraffin waxes, steam distillation condensate through examination of its functionality. A screening procedure was adopted in accordance with Annex VII of the REACH regulation ((EC) No 1907/2006), section 7.13 and sections 2.13.1 and 2.13.4.1 of the Classification, Labelling and Packaging (CLP) Regulation (EC) No.1272/2008. An evaluation of the functionality within the substance has been performed to identify the presence of elements commonly associated with oxidising behaviour.

Executive summary:

An assessment was performed to establish the oxidising potential of Thermal cracking oil from blends of rubber, fuel oils and paraffin waxes, steam distillation condensate through examination of its molecular structure and functionality. A screening procedure was adopted in accordance with Annex VII of the REACH regulation ((EC) No 1907/2006), section 7.13 and section 2.13.4.1 of the Classification, Labelling and Packaging (CLP) Regulation (EC) No.1272/2008. Typical oxidising agents contain functional groups such as halide-oxygen groups, nitrogen-oxygen groups and some metal-oxygen complexes. The raw materials used to manufacture the substance do not contain any halogens or metals, and these elements are not present in the final product. Nitrogen is contained in some of the substrates used as a feedstock in the manufacturing process, as well as Benzonitrile, a minor constituent identified in the substance. However, as stated in Section 2.13.4.1 of the CLP regulation, it is chemically bonded to carbon and hydrogen and therefore does not pose an issue for oxidising potential. Oxygen is contained within the substance Thermal cracking oil from blends of rubber, fuel oils and paraffin waxes, steam distillation condensate and its substrates, however, as stated in section 2.13.4.1 of the CLP regulation, it is chemically bonded to carbon and hydrogen and therefore does not pose an issue for oxidising potential. It can be concluded that Thermal cracking oil from blends of rubber, fuel oils and paraffin waxes, steam distillation condensatehas negligible oxidising potential and does not require classification as an oxidising agent.
