Description of key information
The inhibition of the degradation activity of activated slugde is not anticipated when indroduced in appropriate low concentrations.
Key value for chemical safety assessment
Additional information
A respiration inhibition test was performed with a hydrolysate of the test substance 3,5,5-trimethylhexanoyl chloride following EG-Guideline 88/302/EGW under GLP conditions. The 3-h EC20 was 450 mg/L (BASF AG, 1990). Due to the expected hydrolysis of the test item, the test results may also cover effects from the hydrolysis products.
The effect of 3,5,5-trimethylhexanoic acid on domestic activated sludge was tested in a respiration inhibition test with a duration of 3 h according to OECD 209. The EC50 (3 h) is 470 mg/L, the EC10/NOEC (3 h) corresponds to 230 mg/L (Oxea, 1989). Inhibition of the degradation activity of activated sludge is not anticipated when introduced in appropriately low concentrations.

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.
