<unk>  is a permeation enhancer that temporarily changes the permeation dynamics of the lipid bilayer and opens up the tight junctions between skin cells so active drug molecules can be rapidly absorbed through the skin into systemic circulation. It can also improve the solubility of compounds resulting in enhanced drug permeation.
