Description of key information
Allantoin is readily biodegradable.
Key value for chemical safety assessment
- Biodegradation in water:
- readily biodegradable
Additional information
In an experimental study, conducted in 2005, GLP-compliant and in accordance with OECD guideline 301B, biodegradability of Allantoin was tested in a CO2 -evolution test. Degradation of Allantoin was 10% after 2.5 days, 60% after 6 days and 76% after 28 days. The 10 d-window was fulfilled and Allantoin was regarded as being readily biodegradable.
In an earlier test, the biodegradability of Allantoin was tested using the Zahn-Wellens method, in accordance with DIN 38412 -25. In this test, degradation of Allantoin was observed to be 92% after 5 days and 95% after 10 days.
It can therefore be concluded from the results of the 301B study, with supporting evidence from the Zahn-Wellens test, that Allantoin is readily biodegradable.
