Additional information

In general, textile chemicals especially textile dyes are designed to be no organic substrates for microorganisms, fungi and higher organisms. Therefore, these substances are considered to be not biodegradable at all. Nevertheless, basic studies to assess biodegradability of the test item have been performed.

A key study reported biological elimination of FAT 40032 as 8 %. BOD5 and COD values of 13 and 935 mg O2/g were reported in two other key studies respectively. Based on the BOD5/COD quotient which is not >0.5, the substance is not indicative of rapid degradation.

Taking data from % degradation test and BOD5/COD quotient into account, the test substance FAT 40032 is not biodegradable.
