Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Activated sludge: EC0>2000mg/l
POLYSEED: IC10=5000mg/l, IC50>50000mg/l
Sewage sludge microorganisms: IC50>5000mg/l

Key value for chemical safety assessment

EC10 or NOEC for microorganisms:
2 000 mg/L

Additional information

In an activated sludge respiration inhibition test, no inhibition was found up to the maximum tested concentration of 2000mg/l. In a Microtox assay using a photobacterium, the IC50 was not reached up to the maximum tested concentration of 5000mg/l. Against a broad spectrum micro-organisms mixture an IC10 of 10000mg/l and an IC50 of 23500mg/l was established. The data indicates that the substance is effectively non toxic to micro-organisms.
