Description of key information
The growth inhibition concentration (IGC50) for piperazine adipate for Tetrahymena pyriformis at 48 hours is estimated to be 916.19 mg/L for effect on growth. Based on this value it can be concluded that piperazine adipate is not toxic to aquatic environment based the criteria given by CLP regulation
