Preliminary estimate:
Approximate solubility in n-octanol: > 54.8 % w/w
Approximate solubility in water: 4.63 % w/w
Approximate Pow: > 11.8
Log10 Pow: > 1.07
Applicant's summary and conclusion
- Conclusions:
- Substances having a log10 Pow greater than 3 are regarded as having the potential to bioaccumulate in the environment. According to this conclusion the substance ethyl methyl carbonate seems not to have the potential to bioaccumulate in the environment (log Pow: 0.972)
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
