Description of key information

Based on the data of two tests (Ready biodegradability test - Modified MITI -OECD TG 301 C; and Inherent biodegradability – Zahn-Wellens -OECD TG 302 B ) the test substance FAT 36014 can be concluded to be not-biodegradable and stable in the environment. The hydrolytic stability test, abiotic degradation of FAT 36014/Z as a function of pH in aqueous solution performed according to OECD guideline 111 method C.7(440/2008) concluded that the test item would be stable towards hydrolysis at pH 4, 7 and 9. Also the adsorption to soil and sludge was tested using the HPLC method, the outcome indicates that the test substance does not sorb strongly to soil and sludge and can be regarded as mobile.
