Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
Study results show that potassium allophonate is readily biodegradable.
Key value for chemical safety assessment
- Biodegradation in water:
- readily biodegradable
Additional information
Percent degradation was calculated by expressing BOD as a percent of theoretical oxygen demand (ThOD). The ThOD for the test substance was 0.84 mg O2/mg. The percent degradation for the test substance treatment on Days 7, 14, 21, and 28 was 9.5, 46.7, 78.8, and 72.1%, respectively. For a pure substance to be classified as readily biodegradable, the test substance must reach >60% biodegradation within 10 days of it first reaching 10% biodegradation. Given the results at Day 7 and Day 14, this criteria was met, potassium allophonate may be classified as readily biodegradable.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
