Key value for chemical safety assessment

Water solubility:
2.16 mg/L
at the temperature of:
20.2 °C

Additional information

The water solubility of the test item n-butyl-4,4 -bis(tert-butylperoxy)valerate was assessed using a protocol adapted from the flask method (OECD 105) with slow stirring conditions described in the OECD test guideline 123 and according to GLP requirements (Chastenet, 2017).

Test solutions were prepared at a high loading rate of 5 g/L.

The water solubility of n-butyl-4,4-bis(tert-butylperoxy)valerate in ultra-pure water has been determined to be around 2.16 mg/L.

The test was run at 20.2°C and all pH values were 4.7.
