Conclusions:
Phenol, ethoxylated, esters with acrylic acid (Miramer M142) was submitted to the High Performance Liquid Chromatography with UV detection for the determination of partition coefficient in n-octanol/ Water (Log POW) according to OECD 117 method. LogPOW was determined experimentally for the mono-constituent product (97.94%) to be 2.672 and calculated to be 2.186 using ESCOSAR.
