Applicant's summary and conclusion
- Conclusions:
- log Kow calculated by EPIWIN program was -4.23 to -0.42 for represenative constituents
- Executive summary:
log Kow calculated by EPIWIN program (KOWWIN v1.67 or v1.68) of the US EPA (Environmental protection Agency) QSAR was -4.23 to -0.42 for representative constituents. The calculated value for prop-2 -yn-1-ol was in excellent agreement with the measured value of Hansch et al. (1995) of -0.38.
