Endpoint summary
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 all of the essential parameters determined according to established testing guidelines. Classification issues are discussed in the relevant endpoint summaries.
With regard to classification for corrosiveness to metals, CLP guidance (1) outlines, that 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 melting point at 30.8°C (determined by DSC). Accordingly, corrosiveness to metals may be an issue. However, according to the UN Manual of Tests and Criteria, section 37.1.1 (rev. 6, 2015) testing is not necessary if a substance is corrosive to skin: “If a substance is shown to be corrosive to skin, then it is not necessary to conduct the test for metal corrosion for the purposes of classification.” The submission substance is classified as Skin Corr. 1A. As such, a test on metal corrosion is not required.Based on experience from the handling and use of the substance there is no indication for any metal corrosiveness. In conclusion, the substance is not classified for corrosiveness to metals.
Classification as self-heating is not appropriate for the submission substance: according to ECHA Guidance Document on the application of the CLP criteria (1), the self-heating phenomenon applies only to solids, not to liquids; solids with a melting point below 160°C equally should not be considered for classification according to the guidance document due to the endothermic melting process. The melting point of the submission substance is 30.8 °C and as such pronouncedly below 160 °C.
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 to the submission substance.
Overall, the substance does not have to be classified for physical hazards.
