Additional information

The acute toxicity of Cassia oil towards Daphnia magna was investigated according to OECD guideline 202 under GLP. Daphnids were exposed to nominal WAF's of 0.1, 0.32, 1.0, 3.2 and 10.0 mg/L and observed for 48 hours. The 48h-EL50 was found to be 3.8 mg/L based on nominal concentrations (loading rate).
