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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

2)Acute toxicity to Daphnia magna.
Exposure of Daphnia magna to the test item has been investigated and gave the following results based on the 0-Hour measured test concentrations:
Time Point (Hours): 48 hours
EC50 (mg/L) : 0.64 mg/l
95% Confidence Limits (mg/L) : 0.59 -0.69
NOEC (mg/L) : 0.41
LOEC (mg/L): 0.87
3) Algal growth inhibition test:
The effect of the test item on the growth of Pseudokirchneriella subcapitata has been investigated over a 72-Hour period and based on the geometric mean measured test concentrations gave the following results:
Response Variable |
EC50(mg/L) |
95% Confidence Limits (mg/L) |
No Observed Effect Concentration (NOEC) (mg/L) |
Lowest Observed Effect Concentration (LOEC) (mg/L) |

*It was not possible to calculate 95% confidence limits for the ErC50value as the data generated did not fit the models available for the calculation of confidence limits.
4) Activated sewage sludge:
The effect of the test item on the respiration of activated sewage sludge gave a 3‑Hour EC50value of 310 mg/L, 95% confidence limits 190 - 510 mg/L.
The reference item gave a 3-Hour EC50value of 6.8 mg/L, 95% confidence limits 5.3 – 8.8 mg/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).
