In this guideline (OECD 201) study conducted with GLP certification, the 72 hour EC50 (growth rate) of the test material to freshwater algae was determined to be 14.4 mg/l. The test was conducted under static conditions with test concentrations between 0.32 and 32 mg/l. The study result does not trigger classification as hazardous for the aquatic environment under the the conditions of the Classification, Labelling, and Packaging (CLP) regulation (1272/2008), as the test material is readily biodegradable and has a BCF <500.
Study carried out according to guideline and with GLP compliance.
The key study for the determination of the inhibition of algal growth was conducted according to OECD guideline 201 including analytical test item concentration verification (BASF SE, 2010). The ErC50 (72 h) was 14.4 mg/L based on mean measured test item concentrations. The ErC10 was determined to be 2.51 mg/L
