 concentration of test solutions run #1 5.8 µg/mL 6.6 µg/mL 8.6 µg/mL
 concentration of test solutions run #2 6.1 µg/mL 6.6 µg/mL 8.6 µg/mL
 mean of single determinations 6.0 µg/mL 6.6 µg/mL 8.6 µg/mL
 Water solubility Octylphenol (mean of triple determination)  7.0 µg/mL      
Conclusions:
Interpretation of results (migrated information): slightly soluble (0.1-100 mg/L)
Executive summary:

Water solubility of Octylphenol was determined according to national standard ASTM E 1148 - 02, which is similar to OECD Guideline for Testing of Chemicals No. 105, adopted 27.07.95.

The water solubility was determined to be 7.0 mg/L at a temperature of 20 °C and a pH value of 6 - 7.
