Abstract
The present disclosure relates to a composition for the release of the bioactive substance comprising: sucrose acetate isobutyrate dissolved in an ionic liquid and an additive selected from the list consisting of: chitin, silk fibroin, cellulose, alginate, chitosan, gellan gum, dextrin, collagen, guar gum, carregeenan, heparin, kefiran, or mixtures thereof. By taking advantage of the properties of an ionic liquid (IL), in particular 1-butyl-imidazolium acetate (BMIMAc), it was possible to achieve a good dissolution of SAIB, which combined with chitin and/or silk, natural polymers, allows the development of the structures with different shape and sizes.
