Description of key information

Additional information

The relevant part of the submission item Guanidine carbonate is the Guanidine (CAS 113-00-8) as discussed in the section on Environmental fate and pathways above. It is present as the Guanidinium kation (see section Dissociation constant). The carbonate, is considered negligible for the environmental assessment and disregarded in the following discussion

Guanidine is mobile in soils and has an overall low adsorption potential, but it may act as kation, which moderately could reduce its mobility under certain geochemical conditions.

Volatilization is negligibly low and it is deemed unlikely that Guanidine from the production and use of the submission item Guanidine carbonate reaches the atmospheric compartment in significant amounts.
