Description of key information
Readily biodegradable: 93.1% (CO2 evolution) in 28 days (OECD 301 B)
Key value for chemical safety assessment
Additional information
Two ready biodegradation studies are available for 2,2-dimethyl-1,3-propanediyl dioctanoate (CAS No. 31335-74-7).
The key ready biodegradability study carried out with 2,2-dimethyl-1,3-propanediyl dioctanoate (CAS No. 31335-74-7), was performed following the OECD Guideline 301 B (Bouillon, 1999). Activated sludge was used as inoculum. During the 28-day test period, biodegradation reached 93.1%, based on CO2 evolution, and the 10-day window criterion was met.
For the supporting study carried out with 2,2-dimethyl-1,3-propanediyl dioctanoate (CAS No. 31335-74-7), only a short abstract is available. The study was conducted according to OECD Guideline 301 B (Windeatt, 1995). At the end of the 28-day exposure period, 82% biodegradation was reached, based on CO2 evolution.
In conclusion, 2,2-dimethyl-1,3-propanediyl dioctanoate (CAS No. 31335-74-7) can be considered as readily biodegradable according to OECD criteria.
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.
