Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
- EC50 for microorganisms:
- 135.7 mg/L
- EC10 or NOEC for microorganisms:
- 65.3 mg/L
Additional information
Experimental data for the assessment of toxicity of DODA (CAS 7300 -34 -7) to aquatic microorganisms are available. In a study with Pseudomonas putida according to DIN 38412-8 the 17-h EC50 was determined for not pH-adjusted test solutions to be 135.7 mg/L; the 17-h EC10 was found to be 65.3 mg/L (BASF AG, 1989; report no. 89 -2151). Based on the available experimental data for the test substance, it is concluded that inhibition of the degradation activity of activated sludge is not anticipated when DODA (7300-34-7) is 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.
