Additional information
The acute toxicity of the test Sulfosuccinate of Lanolin Alcohol to Zebra fish (Danio rerio) was determined in a full 96‑hour static test according to: OECD Guideline for Testing of Chemicals, N. 203.
For this purpose, 7 juvenile fish of the species Danio rerio were exposed, after an acclimation period (59 days), to an aqueous test medium containing the active ingredient at five different concentrations, namely 4.3, 9.4, 20.7, 45.5 and 100.0 mg/L, corresponding to 14.2, 31.3, 68.9, 151.5 and 333.3 mg/L as test item (active ingredient content 30 %).
The obtained experimental results allowed to calculate the LC0, the LC50, the LC100 and the NOEC values at 24, 48, 72 and 96 hours.
The LC50 and NOEC values were determined from the Raw Data by the statistical comparison with negative control, while LC0 and LC100 values at each observation time were directly extracted from the Raw Data.
The LC50 was defined > 100 mg/L of active substance (corresponding to > 333.3 mg/L of test item nominal concentration) at 96 hours, the NOEC 100 mg/L of active substance (corresponding to 333.3 mg/L of test item nominal concentration) at 96 hours.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
