Description of key information

The test material is designed to be used as a dye for diverse textile fabrics. To ensure high performance and quality of the treated fabric, these class of chemicals are designed to be not biodegradable by microorganisms.

Neverthe less, data from a study performed according to a guideline which is equivalent or similar to OECD 303 A, showed 98 % bioelimination (TOC removal) at the end of a 28-day exposure period.

Further, the BOD5/COD quotient calculated using data from several individual studies (BOD: 42 mg/g O2; COD: 1120 mg O2/g) is less than 0.5, indicating the test substance as not rapidly biodegradable.

Taking the data from key study and supporting studies into account, the test substance FAT 36038 is considered to be not biodegradable.
