Additional information
Two studies are available in order to determine the acute toxicity of substances belonging to the stilbene fluorescent whitening agents category to terrestrial macroorganisms. The EC50 value inEisenia foetidaaccording to OECD 207 was greater than 1000 mg/kg dry weight (CAS 16090-02-1, CIBA - GEIGY 1991). This result was substantiated by a limit test that determined a LC50 value greater than 5000 mg/kg dry weight (CAS 16090-02-1, Solvias 1999).
