Administrative data

Description of key information

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

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.

 

In addition, classification for corrosiveness to metals was checked. According to (1), the following substances and mixtures should be considered for classification in this class:

• substances and mixtures having acidic or basic functional groups;

• substances or mixtures containing halogen;

• substances able to form complexes with metals and mixtures containing such substances.

 All these criteria do not apply to the submission substance. Further, experience from the handling and use of the substance did not indicate any corrosion hazard to metals. In conclusion, the submission substance is out of scope with regard to corrosivity to metals.

According to (1), the phenomenon of self-heating applies only to solids. The surface of liquids is not large enough for reaction with air and the available test method is not applicable to liquids. Therefore liquids are not classified as self-heating.

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 Reommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria;”

This applies for the submission substance.

 

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