EC number: 924-903-2 | CAS number: -
With high probability not harmful to aquatic algae. No toxic effects occur at the range of the substances solubility.EL50 (72h) and EL10 (72h) > 100 mg/L (nominal, WAF) for growth rate of Desmodesmus subspicatus (OECD 201)
In a GLP guideline study following OECD 201 green algae (Desmodesmus subspicatus) were exposed for 72 hours to
Hexamethylene diisocyanate, oligomers, blocked with dibutylamine [BASF SE, 2012]. Based on the low water solubility of the test item the aquatic toxicity was determined by a water accommodated fraction (WAF) with a nominal loading rate of 100 mg/L. No algal growth inhibition was observed in the treatment compared to the control. Thus, the 72-h EL50 and EL10 for growth rate inhibition is determined to be > 100 mg/L based on nominal concentrations.
