Biodegradation in water: screening tests
The test item is considered to be readily biodegradable.
Biodegradation in water and sediment: simulation tests
The study does not need to be conducted as the test item is highly insoluble in water, hydrolytically unstable and readily biodegradable.
Biodegradation in soil
The biodegradation test with the test substance Sika Hardener LH was performed in accordance with "Method for Testing the Biodegradability of Chemical Substances by Microorganisms" stipulated in the "Testing Methods for New Chemical Substances" (Ministry of Health, Labour and Welfare, Ministry of Economy, Trade and Industry, Ministry of the Environment, Japan). Under the test conditions of the biodegradation study, the test substance Sika Hardener LH was completely hydrolyzed to 2,2-dimethyl-3-oxopropyl dodecanoate and hexamethylenediamine. These converted products were biodegraded. The percentage (average) of biodegradation by BOD was 91% after 28 days. Further, the test substance is considered to be readily biodegradable.
