Description of key information

Generally it states that Ethyl centralite is insoluble in water. Only two specific values for water solubility were found.
The value log Kow = 4.2 (calculated value) was used for calculation of water solubility WS = 4.79 mg/L.
The value WS = 80 mg/L was stated in study without further detailed information.
Supporting information
Alga, Growth Inhibition Test - solubility in Test medium
nominal concentration: 100 mg/L
measured concentration: 47.3-52.4 mg/L (saturated solution - 72 hrs stirring)
Daphnia magna, Acute Immobilisation Test - solubility in Dilution water
nominal concentration: 49 mg/L
measured concentration: 51.9 mg/L (saturated solution - 72 hrs stirring)
nominal concentration: 100 mg/L
measured concentration: 49,9 - 50.2 mg/L (saturated solution - 72 hrs stirring)

Key value for chemical safety assessment

Water solubility:
80 mg/L
at the temperature of:
20 °C

Additional information

Ethyl centralite has low aqueous solubilities, although the quality of these solubility data may be equivocal. The both values are in range 0.1-100 mg/L for slightly soluble substances.

The key value 80 mg/L was selected with respect to experimental results of analytical method in studies "Alga, Growth Inhibition Test" and "Daphnia magna, Acute Immobilisation Test".
