- Endpoint:
- water solubility
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2009-09-08
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 105 (Water Solubility)
- GLP compliance:

- Type of method:
- flask method
- Key result
- Water solubility:
- 2.4 g/L
- Temp.:
- 20 °C
- pH:
- >= 6.2 - < 6.3
- 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.
