0.021 g/L
Temp.:
20 °C
pH:
6.5
Conclusions:
Interpretation of results (migrated information): slightly soluble (0.1-100 mg/L)
The water solubility of DBPP determined according to the OECD105 guideline is 21 mg/L.
Executive summary:

The water solubility of the test item Dibutyl phenyl phosphate in demineralized water was determined by phosphor (P) of the aqueous phases calculated with the phosphor content of the test item (purity 100%) determined by optical emission spectrometry with inductive coupled plasma (ICP-OES) analysis.

The following water solubilities and pH-values of Dibutyl phenyl phosphate in demineralized water at 20°C were obtained:

- Flask 1: 0.0208 g/L (pH: 6.5)

- Flask 2: 0.0209 g/L (pH: 6.4)

- Flask 3: 0.0202 g/L (pH: 6.5)

- Mean value over the 3 flasks: 0.021 g/L

Description of key information

The water solubility was determined of DBPP was determined by phosphor (P) of the aqueous phases calculated with the phosphor content of the test item (purity 100 %) determined by optical emission spectrometry with inductive coupled plasma (ICP-OES) analysis.(Jungheim, 2013). The average water solubility over 3 tests was 21 mg/L.

Key value for chemical safety assessment

Water solubility:
21 mg/L
at the temperature of:
25 °C
