Additional information
A study was performed to determine the COD value of FAT 36034/D, by following the guideline DEV DIN 38409 - H 41-1 (1980) corresponding to 92/96/EE C C.6., in compliance with the Good Laboratory Practice (GLP) Regulations. A predetermined amount of the test substance FAT 36034/D in water was oxidized by potassium dichromate in a strong sulphuric acid medium with silver sulphate as a catalyst under reflux for 2 hours. The residual dichromate was determined by titration with standardized ferrous ammonium sulphate. The reference substance Potassium hydrogen phthalate solution was tested in a concentration of 20 ml/l.The COD of FAT 36034/D and reference substance was found to be 1747 mg O2/g and 196 mg O2/I respectively. The study reported the value of greater than 1000 mg /g O2 for COD.Relevant is the BOD5/COD quotient which is not >0.5, therefore, the substance is not indicative of rapid degradation. Taking all data into consideration, the test substance FAT 36034 is considered to be not biodegradable.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
