Description of key information
The results of the 21-day chronic toxicity study of 2-ethylhexan-1-ol to Daphnia are used in the risk assessment for the parent substance. The peroxide bis(2-ethylhexyl) peroxydicarbonate hydrolyses instantly (half-life < 1 h). 2-ethylhexan-1-ol is the main degradation product of the peroxide. In the hydrolysis test it is formed at proportions of 84.4-96.6% . Therefore, the 21-d NOEC (reproduction of Daphnia) of 2-ethylhexan-1-ol of 1.6 mg/L is used in the risk assessment of bis(2-ethylhexyl) peroxydicarbonate.

Additional information
The 21-day chronic toxicity of 2-ethylhexan-1-ol to Daphnia magna was studied under semi-static conditions. Daphnids were exposed to the test chemical at nominal concentrations of 150, 75, 18.75, 9.38, 4.69, 2.34 and 0 mg/L. The 21-day NOEC based on reproduction was 2.3 mg/L (nominal, corresponding to 1.6 mg/L actual). The sublethal effects were related to reproduction rate and first occurrence of offspring. Production of offspring in the treated groups indicated that 2-ethylhexan-1-ol had an effect on the reproduction at concentrations greater than 2.3 mg/L (nominal).
This study is considered as acceptable and satisfies the guideline requirements for a chronic toxicity study with freshwater invertebrates.
