Remarks:

based on examination of the structural formula.

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

 The molecule does not contain any functional groups listed in Table 23:1. 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:

o 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 HER (Resorcinol bis-(2-Hydroxyethyl) ether, 2-[3-(2-hydroxyethoxy)phenoxy]ethanol the proportion of electronegative atoms in the molecule is low (4 oxygen atoms out of an overall atom count of 28). All oxygen atoms are bound to carbon atoms.

o the electronegative atoms are bonded to each other or to other electronegative elements such as iodine, nitrogen, sulphur or phosphorus.

 In the case of HER (Resorcinol bis-(2-Hydroxyethyl) ether, 2-[3-(2-hydroxyethoxy)phenoxy]ethanol, the electronegative atoms are not bound to one another, nor to any other electronegative elements.

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

In every respect of the oxidising liquids exemption procedure, HER (Resorcinol bis-(2-Hydroxyethyl) ether, 2-[3-(2-hydroxyethoxy)phenoxy]ethanol does not show any evidence of possessing oxidising properties.

Interpretation of results:

GHS criteria not met

Conclusions:

On the basis of this exercise, the material should be considered as not oxidising and should not be subjected to experimental testing. The material meets all criteria for exemption from testing and has a structure not at all conducive with that required to exhibit oxidising tendencies.
