Endpoint:

oxidising liquids

Data waiving:

study scientifically not necessary / other information available

Justification for data waiving:

the study does not need to be conducted because there are no chemical groups present in the molecule which are associated with oxidising properties and hence, the classification procedure does not need to be applied

Remarks on result:

other: The substance does not show any evidence of possessing oxidising properties

Examining the structural formula, the following observations can be made:

·        The molecule does not contain any functional groups imparting oxidising properties. Although this list is not exhaustive, this is a significant observation as most commonly occurring oxidising functional groups are contained within the list.

·        According to the two criteria quoted, oxidising properties can exist when:

(1) the electronegative atoms which are present constitute a high proportion of the molecule and are bound to elements in a high oxidation state. In the case of the test substance the proportion of electronegative atoms in the molecule is low (3 oxygen atoms out of an overall atom count of 79 to 82).

(2) the electronegative atoms are bonded to each other or to other electronegative elements such as iodine, nitrogen, sulphur or phosphorus. In the case of the test substance, the structure contains an O=S=O bond but this is highly unlikely to present oxidising properties.

Assessment against these two criteria indicates strongly that the molecule will not have oxidising properties.

Interpretation of results:

GHS criteria not met

Remarks:

Not oxidizing

Conclusions:

The test substance does not show any evidence of possessing oxidising properties.

Description of key information

Based on the molecular structure of the substance, no oxidising properties are expected. This conclusion was supported by a theoretical assessment (K2, Dekra, 2018).

Key value for chemical safety assessment

Oxidising properties:

non oxidising

Justification for classification or non-classification

The structure of the test substance contains no groups that would infer oxidising properties.
