- Executive summary:
A test was carried out according to DEV DIN 38'409 - H 41 -1 (1980) corresponding to 92/96/EEC C.6 to determine COD of FAT 20036/F. The test was performed in compliance with the Good Laboratory Practice (GLP) Regulations of Switzerland.
A predeterminated amount of the test substance FAT - 20'036/F dissolved in water is oxidized by potassium dichromate in a strong sulphuric acid medium with silver sulphate as a catalyst under reflux for 2 hours. The residual dichromate is determined by titration with standardized ferrous ammonium sulphate.
The test substance was tested with a sample weight of 10.0 mg. The reference substance, Potassium hydrogen phthalate solution was tested in a concentration of 20 ml/I.
The COD of FAT - 20036/F was found to be 493 mg 02/g The COD of the reference substance was found to be: 201 mg O2/L. Taking the results of the corresponding BOD5 test into account, the rsulting BOD5/COD quotient is zero and therefore no biodegradation can be expected.

Calculation of the BOD5:
When the test substance is not soluble in water and the determination of the BOD5 under the conditions of ISO 5815 is not possible, the BOD5 of the test substance is given by the equation:
BOD * (mg O2 / mg Test substance) =
((mg O2/l uptake by Test substance) - (mg O2/l uptake by blank)) (1) / mg/l Test substance X 1000
1) BOD Measurement at day 5
BOD5 = 0 mg 02/g
Description of key information
Three independant key studies, according to OECD Guideline and GLP were performed to determined COD, BOD5 and the inherent biodegradability of FAT 20036/F.
The COD was found to be 493 mg O2/gr, BOD5 to be 0 mg O2/gr and the inherent biodegradbility to be 0%.
Based on theBOD5/CODquotient which is not >0.5, the substance is not indicative of rapid degradation.
Taking the data from degradation test and BOD5/COD quotient into account, the test substance FAT 20036 is considered to be not biodegradable.
Supporting studies were performed on different batches (A, B, C, D and E) to determine BOD, COD and biodegradtion values.
- FAT 20036/A: COD is found to be 994 mg/ gr O2, BOD5 to be 130 mg/gr O2 and the inherent biodegradability to be 69% after 31 days.
- FAT 20036/B:COD is found to be 1085 mg COD/ gr, BOD5 to be 17 mg/gr O2.
- FAT 20036/C:COD is found to be 811 mg/ gr O2, BOD5 to be 0 mg/gr O2.
- FAT 20036/D:COD is found to be 757 mg/ gr O2, BOD5 to be 16 mg/gr O2.
- FAT 20036/E: COD is found to be 807 mg/ gr O2, BOD5 to be 250 mg/gr O2 and the inherent biodegradability to be 83% DOC after 28 days.
The inherent biodegradability test and the BOD5/COD ratio (<0.5) indicate that the test substance FAT 20036 is not expected to be readily biodegradable.
Key value for chemical safety assessment
- Biodegradation in water:
- inherently biodegradable
Additional information
By the nature of their design and use, acid dyes are not intended to be readily biodegradable as this would assist in the rapid destruction of the dyestuff, rendering it unfit for purpose. As such, it is accepted that such substances are not readily biodegradable under relevant environmental conditions. A published study (Pagga & Brown, 1986) describes the results of the testing of 87 dyestuffs in short-term aerobic biodegradation tests. The authors of this publication concluded that dyestuffs are very unlikely to show any significant biodegradation in such tests and that 'there seems little point in carrying out such test procedures’ on dyestuffs.
There are ISO, European, American (AATCC) and national standards for the colour fastness of dyes. Dyes are required to have specific fastness properties. If the dyes were biodegradable, it would not be possible for them to have these fastness properties.
