Information on environmental fate and pathyways, in particular on
biodegradation, is deduced by read-across from studies for L-arginine.
L-arginine-HCl as such is not a natural constituent of peptides
and proteins. L-arginine-HCL is the salt resulting from the reaction of
the basic L-arginine with HCl. Due to is higher water solubility
L-arginine-HCl is often preferably applied than L-arginine, in
particular when bioavailability is desired property for the intended use.
L-arginine-HCl dissociates in aqueous solution to ionic L-arginine
as well as H+and Cl-. The inorganic ions resulting
from physiological concentrations are not of concern for toxicokinetics
as the “background” concentration in the body is by magnitudes higher
In a GLP-guideline study L-arginine showed 100% degradation after 28
days and therefore can be considered as readily biodegradable. Thus,
L-arginine-HCl can be considered as readily biodegradable, too.
studies are waived in accordance with REACH.
