In vitro investigations on skin permeability of 1,3-butylene glycol with
abdominal skin of rats showed that the test item can penetrate the
skin.Values for permeation clearance were between 2.5 to 7.5 µg/h. These
data were comparable to the values obtained with ethylene glycol, which
was tested under identical conditions (Hatanaka et al., 1994).
The study allows for the reliable comparison with the well characterised
ethylene glycol under identical experimental conditions.
