Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Additional information
Available screening data show that potassium allophonate is readily biodegradable. A closed bottle ready biodegradability test performed according to Organisation for Economic Co-operation and Development (OECD) Testing Guideline 301D and in accordance with Good Laboratory Practice (GLP) requirements showed the allophonate reached >60% biodegradation within the 28-day test (ABC Laboratories, 2013). Percent degradation was calculated by expressing biochemical oxygen demand (BOD) as a percent of theoretical oxygen demand (ThOD), which was calculated to be 0.84 mg O2/mg. The percent degradation on days 7, 14, 21, and 28 was 9.5, 46.7, 78.8, and 72.1%, respectively. Since >60% biodegradation was achieved within the 28-day test (the ten day window did not apply due to the test substance being a mixture), potassium allophonate may be classified as readily biodegradable.
No data from water simulation tests are available, however reliable screening data were available from tests performed according to GLP; therefore a waiver is proposed for simulation testing. According to Column 2 of Annex IX of the REACH Regulation these studies are not necessary as available screening tests confirm that potassium allophonate is readily biodegradable.
Further, no data are available from soil simulation tests, therefore a waiver is proposed based on the results of GLP screening data. According to Column 2 of Annex IX of the REACH Regulation these studies are not necessary as available screening tests confirm that potassium allophonate is readily biodegradable.
