Result: With one exception all constituents [Constituent 1 with CAS 132-29-6, Constituent 3 with CAS597-79-5 and Impurity with CAS 132-28-5] have an estimated water solubility < 0.01 mg/L – these components of the multi-constituent substance ‘Reaction mass of biphenyl-2-yl diphenyl phosphate and triphenyl phosphate and bis(biphenyl-2-yl) phenyl phosphate’ are insoluble in water.

 

The remaining constituent [Constituent 2 with CAS 115-86-6 and a typical concentration range of 20-25%] is slightly soluble (0.1-100 mg/L) in water. This substance has an estimated water solubility of ~ 1mg/L and an experimental value of 1.9 mg/L.

 

Hence, the overall result is:

Water solubility = < 0.01 to 1.9 mg/L 

Applicant's summary and conclusion

Conclusions:
Interpretation of results (migrated information): slightly soluble (0.1-100 mg/L)
Water solubility of three constituents of 'Reaction mass of biphenyl-2-yl diphenyl phosphate and triphenyl phosphate and bis(biphenyl-2-yl) phenyl phosphate': < 0.01 to 1.9 mg/L  (estimated by calculation)
