Description of key information

There are no classification requirements with regard to physico-chemical properties for the submission substance.

Relevant key information is given in the endpoint summaries on the respective properties.

For a summary and conclusion with regard to overall physical hazards and respective classification and labelling requirements, see below!

Additional information

A full set of physico-chemical information is available with many of the essential parameters determined according to established testing guidelines. Classification issues are discussed in the relevant endpoint summaries.

With regard to self-heating properties, according to ECHA Guidance Document on the application of the CLP criteria (1), solids with a melting point below 160°C should not be considered for classification due to the endothermic melting process.

With regard to classification for self-reactiveness, according to CLP, Annex I, 2.8.4.2. "The classification procedures for self-reactive substances and mixtures need not be applied if:

(a) There are no chemical groups present in the molecule associated with explosive or self reactive properties. Examples of such groups are given in Tables A6.1 and A6.2 in Appendix 6 of the UN Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria;" (2). This applies for the submission substance.

The submission susbstance does not contain any peroxide groups and is therefore out of scope with regard to classification as organic peroxide.

In addition, classification for corrosiveness to metals was checked. According to (1), only liquid substances as well as solids that may become liquids (melting point < 55°C) must be taken into consideration here. The submission substance has a wide melting range: while the onset temperature is slightly below this limit (51.5°C), the endothermic melting range peak is at 76.5 °C and the upper melting range temperatue 85°C. It is therefore out of scope with regard to corrosivity to metals.

Overall, the substance does not have to be classified for physical hazards.
