Applicant's summary and conclusion

Conclusions:
Interpretation of results (migrated information): slightly soluble (0.1-100 mg/L)
Executive summary:

Water solubility of Nonylphenol 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 5.7 mg/L at a temperature of 25 °C and a pH value of 6 - 7.
