Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Additional information
The assessment of the aquatic toxicity of β-fructofuranosidase is based on read-across data available for the enzymeα-amylase. This read-across is justified in detail within the analogue justification in IUCLID Section 13.
Experimental data is available for fish, aquatic invertebrates and aquatic algae. Toxic effects on fish and aquatic invertebrates were not observed up to a test substance concentration of 100 mg/L. The most sensitive organisms were algae. An ErC50 (72h) of 49 mg/L (nominal) corresponding to 5.2 mg aep/L was determined for Desmodesmus subspicatus (NOErC (72 h): 25 mg/L (nominal) corresponding to 2.6 mg aep/L). The results are based on the active enzyme protein (aep) content, which represents a value based on a theoretical pure and totally active enzyme.
The substance is not expected to inhibit the degradation process in conventional sewage treatment plants based on the ready biodegradability of the substance. Toxic effects on microorganisms are not likely based on the ready biodegradability of the substance (99 % after 28 d, OECD 301E; read-across).
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.
