Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Fish: No mortality was observed following the exposure of rainbow trout to the test substance at a concentration of 227.9 mg enzyme concentrate dry matter/L. Due to the low toxicity of the test material, the 96-hour LC50 value of the substance was unable to be calculated. Therefore, the 96-hour LC50 value for the test substance with rainbow trout was determined to be > 227.9 mg enzyme concentrate dry matter/L (equivalent to >103.7 mg active enzyme protein/L). The no-observed effect concentration (NOEC) was 227.9 mg enzyme concentrate dry matter/L (equivalent to 103.7 mg active enzyme protein/L).
Daphnia: No immobilisation was observed following the exposure of Daphnia magna to the test substance at a concentration of 227.9 mg enzyme concentrate dry matter/L. Due to the low toxicity of the test material, the 48-hour EC50 (immobilisation) value of the substance was unable to be calculated. Therefore, the 48-hour EC50 value of the test substance to Daphnia magna was >227.9 mg enzyme concentrate dry matter/L (equivalent to 103.7 mg active enzyme protein/L). The no-observed effect concentration (NOEC) was ≥ 227.9 mg enzyme concentrate dry matter/L (equivalent to ≥ 103.7 mg active enzyme protein/L).
Algae: Glucoamylase, batch PPY24900 did not inhibit the growth of Pseudokirchneriella subcapitata, Strain No. CCAP 278/4 at a concentration of 227.9 mg enzyme concentrate dry matter/L under the conditions of this test. Both ErC50 and EbC50 (0 - 72 hours) were > 227.9 mg enzyme concentrate dry matter/L (equivalent to > 103.7 mg active enzyme protein/L). The no-observed-effect concentration NOEC was 227.9 mg enzyme concentrate dry matter/L (equivalent to 103.7 mg active enzyme protein/L).
Additional information
PNEC will be based on EC50/NOEC of 103.7 mg active enzyme protein/L.
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.
