Application

Isosorbide dimethyl ether (DMI), a sustainable solvent, is widely used in various cosmetic and pharmaceutical formulations.
General applications:
  • DMI can be used as an alternative green solvent for epoxidation of cyclooctene, Baylis–Hillman reaction of isomaltulose-derived aldehydes with α,β-unsaturated ketones and also in solid-phase synthesis.
  • It can be used as a coalescent for water-borne paints, where it acts as a co-solvent during the water loss phase and as a coalescing agent during the film formation.

The occluded vasoconstrictor assay was used to assess the effect of penetration enhancers on the topical bioavailability of a representative steroid, betamethasone 17-benzoate, with dimethylisosorbide (DMI) as a reference solvent. In the initial test, only N-methyl-2-pyrrolidone (NMP) increased the steroid
