Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
OECD 301D: 28 % in 28 days based on oxygen consumption
Key value for chemical safety assessment
- Biodegradation in water:
- inherently biodegradable, not fulfilling specific criteria
Additional information
Sulfopropyl acrylate (SPA) is not readily biodegradable in the aquatic environment (28% in 28 d) based on an OECD 301D (Mead, 2001). The ECHA guidance R7b states (ECHA 2014) “Biodegradation above 20% of theoretical (measured as BOD, DOC removal or COD) may be regarded as evidence of inherent, primary biodegradability”. Therefore, Sulfopropyl acrylate (SPA) is regarded as inherently biodegradable, not fulfilling specific criteria.
The toxicity control was degraded by 27% within 15 d. Since the biodegradation was > 25% the test substance is not considered to be inhibitory to the inoculum.
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.
