Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Description of key information

Hydrolysis: 

A GLP-Study accoridng to OECD Guideline 111 was Performed with Guanidine carbonate.

According to the the read-across justification only the gunidinium kation is relevant for the hydrolytical properties of guanidine salts.

Therefore the the study performed with Guanidine carbonate was taken as read-across source to fulfill the information requirements for guanidine hydrochloride.

The pre-test indicated a half-life at 25 °C of more than one year.

Thus no DT50 was determined and the guanidine kation is considered hydrolytically stable under environmental conditions.

  

Photodegradation

Due to the low vapour pressure the substance under investigation will not be present in the gas phase in the atmosphere in appreciable amounts and therefore the elimination path photodegradation in air will be only of minor importance.
