Description of key information

The substance is a reactive dye used for dyeing of textile fabrics and garments. Such substances are designed to be not be biodegradable at all. Nevertheless, basic data to access potential biodegradation have been performed. Key studies describe experimental techniques and results obtained in inherent biodegradation studies of FAT 41001/F. The most reliable study was performed according to OECD Guideline for testing chemicals No.302B, and biodegradation of FAT 41001/F after 28 d was 19 %, confirming that the substance should not be considered as readily biodegradable under the conditions of this test. In addition, determination of BOD and COD values and calculation of the BOD5/COD quotient resulted in a value close to zero. In additional supporting studies, the BOD/COD ratio was found to be value close to zero. Based on this estimation the substance is regarded to be not biodegradable.
