Description of key information

The toxicity of L-arginine-HCl to microorganisms is estimated by read-across from L-arginine.

EC 10 > 10 g/kg

Key value for chemical safety assessment

EC10 or NOEC for microorganisms:
10 000 mg/L

Additional information

L-Arginine did not show toxicity to microorganisms in a test according to (draft) DIN 38 412, L8 with the test organism Pseudomonas putida. The EC10 after 16 h was > 10 g/kg.

There is weight of evidence from the behaviour of L-arginine-HCl in aquous soluation that read-across from L-arginine to L-arginine-HCL is justified for the endpoint toxicity to microorganisms.
