According to the CLP Regulation (EC) No 1272/2008, Section 2.13.1, an oxidising liquid is defined as ‘a liquid substance or mixture which, while itself not necessarily combustible, may, generally by yielding oxygen, cause, or contribute to, the combustion of other material.’

 

A screening procedure has been used to assess the oxidising properties of dihydronepetalactone. This has taken into consideration the following:

 

1. Annex VII of the REACH regulation ((EC) No 1907/2006), section 7.13, which states that a study of the oxidising behaviour of a substance need not be conducted if the substance ‘is incapable of reacting exothermically with combustible materials, for example on the basis of chemical structure (e.g. organic substances not containing oxygen or halogen atoms and these elements are not chemically bonded to nitrogen or oxygen.’)

 

2. Section 2.13.4.1 of the CLP regulation covering oxidising liquids states that for organic substances, the classification procedure shall not apply if:

a)The substance does not contain oxygen, fluorine or chlorine; or

b)The substance contains oxygen, fluorine or chlorine and these elements are chemically bonded to carbon or hydrogen.

 

An evaluation of the functionality within the substance has been performed to identify the presence of elements commonly associated with oxidising behaviour. 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, nitrogen, or metals, and these elements are not present in the final product.  Oxygen is contained within the substance dihydronepetalactone, 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.

Interpretation of results:

GHS criteria not met

Conclusions:

Dihydronepetalactone does not have oxidising potential and does not require classification as an oxidising agent.

Executive summary:

An assessment was carried out based on an examination of the functionality within the substance.  The constituents of dihydronepetalactone are not considered to have chemical functionality associated with with oxidising properties.  Therefore, it is concluded that dihydronepetalactone does not have oxidising potential and does not require classification as an oxidising agent.
