Conclusions:
Water solubility: 2.4 g/L at 20 °C.
Executive summary:

The water solubility of Di-Pentaerythritol was analysed by the flask method according to OECD guideline 105. 450 mg of the substance was added in triplicate to 50 mL of water. The three saturated solutions were then agitated at 30 °C for 24, 48 and 72 h respectively. Each flask was allowed to equilibrate for 24 h at 20 °C with occasional shaking. The aqueous phases were centrifuged and the content of the substance in the aqueous phases was determined by HPLC. A water solubility of 2.4 g/L at 20 °C was determined.
