Description of key information

Hydrolysis:

In accordance with REACH Annex XI, the "Hydrolysis as a function of pH" does not need to be conducted as the test is scientifically unjustified respective technically not feasable. The guanidine ion is expected to have such a long hydrolysis half-life at environmentally relevant pH that the measurement is not feasable. This is concluded from abiotic biodegradation control with river water (Mitchel, Chemosphere, 1987).

Biodegradation:

Guanidine Thiocyanate was proven to be inherently biodegradable in an OECD guideline 302B study.
