Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Endpoint summary
Administrative data
Description of key information
Relevant key information on physico-chemical endpoints is given in the respective endpoint summaries.
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.
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.
Finally, the test item does not contain any of the following chemical groups according to the UN Manual of Tests and Criteria (2) indicating self-reactive properties in organic materials:
Structural feature Examples
Mutually reactive groups: Aminonitriles, haloanilines, organic salts of oxidizing acids S=O: Sulphonyl halides, sulphonyl cyanides, sulphonyl hydrazides
P-O: Phosphites
Strained rings: Epoxides, aziridines
Unsaturation: Olefins, cyanates
Therefore, the test item does not possess self-reactive properties.
Overall, the substance does not have to be classified for physical hazards.
