Description of key information

The boiling point of the registered substance, Reaction mass of disodium N-coco acyl-L-glutamate and sodium N-coco acyl-L-glutamate, has been addressed based on read across to the following three analogues:
Sodium N-coco acyl-L-glutamate: The test material decomposed prior to melting, Walker (2008)
Sodium N-lauroyl-L-glutamate: The test material decomposed, Walker (2008)
Sodium N-myristoyl-L-glutamate: The test material decomposed with melting, Butler (2008)
Based on the read-across data, the registered substance is expected to decompose prior to melting, therefore a boiling point cannot be determined.
Furthermore, in accordance with point 7.3 of Column 2 (Specific rules for adaptation from Column 1), Annex VII of the Regulation (EC) No. 1907/2006 (REACH), this study does not need to be conducted if the substance decomposes prior to boiling. Based on the submitted read across data, the substance is considered to decompose prior to melting, and therefore testing is not technically possible.
