EC number: 239-701-3
CAS number: 15625-89-5
short-term toxicity tests for the registered substance are available for
fish, algae and for daphnia.
acute fish studies are available. In the key study the acute toxicity of
the test substance to Danio rerio exposed under semi-static conditions
for 96h was assessed according to the OECD 203 Guideline. Fish were
exposed to a series of test solutions renewed every day throughout the
test period. Test item concentrations were determined at each
observation time on fresh and old solutions: as chemical analysis of
test samples taken on fresh and old solutions indicated that measured
concentrations of the test item did not remain within 80-120% of the
nominal concentrations and were not maintained over a 24h test period
(i.e. deviation >20%), the exposure concentrations were based on the
geometric mean of measured concentrations. LC50 was determined at 0.87
the two available acute daphnia study, Daphnia Magna were exposed for
48h in a static system. The EC50 of the key study was 19.9 mg/L (Dr.
the one available algae study, the 96h-ErC50 for growth rate was 4.9 mg/L
toxicity data for algae is available with an ErC10 (72h) of 1.9 mg/L.
to Annex I of this regulation, the chemical safety assessment triggers
further action when the substance or the preparation meets the criteria
for classification as dangerous according to Directive 67/548/EEC or
Directive 1999/45/EC or is assessed to be a PBT or vPvB. The hazard
assessment of the substance reveals that the substance is a not a PBT or
vPvB substance, and the safety assessment did not show further
indications of that the substance may constitute a risk to the
environment. Therefore, long-term toxicity studies for fish and
invertebrates are not provided.
reliable study assessing the toxicity of the registered substance to
microorganisms is available. The EC20 was determined to be 625 mg/l.
