96 h LC50 >100 mg a.i./L (OECD TG 203; Danio rerio; semi-static, natural river water containing 3.46 mg/L TOC (2.71 mg/L DOC)) RL1; GLP
a 96 h acute toxicity study according to OECD guideline 203, adopted 17
July 1992, zebrafish (Danio rerio) were exposed to
Undecylenamidopropyl Betaine at nominal concentrations of 0 (control)
and 100 mg a.i./L under semi-static conditions in natural river water
containing 3.46 mg/L TOC (2.71 mg/L DOC). Measured test item
concentrations were in agreement with nominal (93-102%). These
concentrations remained stable during both renewal periods. Given these
results, effect parameters can be based on the nominal test
mortality or other clinical effect was observed at the limit
concentration and the control during the 96-hour test period. The 96 h
LC50 was >100 mg a.i./L.
