Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
The inhibition of the degradation activity of activated sludge is not anticipated when introduced in appropriate low concentrations.
Key value for chemical safety assessment
- EC10 or NOEC for microorganisms:
- 100 mg/L
Additional information
No data on the toxicity of octanoyl chloride in microorganisms is available. However, since the test substance rapidly hydrolyses in water invertebrates are mainly exposed to the hydrolysis product, octanoic acid.
Data presented in the ECB IUCLID data set report an EC10 of 100 mg/L in a growth inhibition test on Pseudomonas putida (Henkel KGaA cited in ECB, 2000). Results of this test can be used for the calculation of the PNECmicroorganisms since no other relevant data are available.
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.
