Subchronic [RfD] Comments: |
Based on route to route extrapolation using an absorption factor of 0.5. Calculated from data obtained with methoxyethanol converted by multiplying by the molecular weight ratio (118.13/76.09). |
Chronic [RfD] Comments: |
Based on route to route extrapolation using an absorption factor of 0.5. Calculated from data obtained with Methoxyethanol converted by multiplying by the molecular weight ratio (118.13/76.09). |
General Comments: |
No pharmacokinetic data were provided to justify route to route extrapolation for the oral [RfD] values. |
