The OECD 301B method is designed to provide the screening of chemicals for ready biodegradability in an aerobic aqueous medium. Samples are required to achieve a threshold of 60% degradation based on the maximum available carbon from a given sample formulation. Total carbon is determined analytically for each sample and used as the reference for the determination of the percentage of carbon dioxide (% ThCO2) produced by microbiological degradation.
For the purpose of determining biological degradation, two criteria can be achieved. Ready Biodegradability can be achieved by obtaining the 60% threshold within a 10 day-window within the 28 days of testing. The second criteria, Ultimate Biodegradation, can be achieved if the amount of biodegradation meets or exceeds the 60% threshold at a time point determined in the test (e.g. when the rate of degradation reaches a plateau). For each of these criteria, when achieved, the sample also achieves the requirements needed for classification as 'Inherent Biodegradability'.
One test sample was submitted for OECD 301B biodegradation testing. The result data and graphs were analyzed by curve fit to establish a plateau for the rate of biodegradation.
Sample 1 - PhytoVie Defense, INCI: Brassica Campestris/Aleurites Fordi Oil Copolymer, Lot# 520818 - was a straw colored clear hydrophobic liquid and was introduced into the test system dispersed onto silica gel. The sample graph attached shows the test chamber carbon dioxide (C02) measurement as the percent of theoretical maximum (% ThC02). Average values are plotted with the standard deviation (+/- SD) for the time course of the test. Curve fit is applied to calculate the predicted fit (blue line). If present, (green) shading below the curve fit applies to the biodegradation requirement (10 to 60% ThC02) for the determination of Biodegradability and shows that the required degradation amount has been met.
Ready Biodegradability requires that this degradation occur within a 10-day window during the test
duration of 28 days.
The test sample did not achieve the requirements for Ready Biodegradability by the OECD 301B standard. The test sample achieved an inherent degradation of 32% ThCO2within 28 days of the test timeframe. A degradation plateau was not achieved within the 28 days of testing.
Applicant's summary and conclusion
- Validity criteria fulfilled:
- yes
- Interpretation of results:
- inherently biodegradable
- Conclusions:
- The test sample achieved an inherent degradation of 32% ThCO2 within 28 days of the test timeframe.
