Abstract: The present disclosure relates to powdered, rehydratable, bacterial cellulose formulations comprising methods of production and uses thereof. In particular the use of the formulation as a colloid stabilizer, foam stabilizer, or as a thickener, as a reinforcer material (as a filler), a dietary fibre, a foodstuff, a cosmetic or pharmaceutical composition, a composite, among others. An aspect of the present subject matter discloses a powdered formulation, comprising bacterial cellulose and an additional component (or third component) selected from the following list: sodium carboxymethyl cellulose, carboxymethyl cellulose, xanthan, methylcellulose, methyl cellulose, hydroxyethyl-cellulose, hydroxyethyl-cellulose, hydroxypropyl methyl cellulose, hydroxypropyl methylcellulose, tylose, glycerol, saccharose, or mixture thereof; wherein the powdered formulation is dispersible in an aqueous media, at 20° C., with low shear mixing.

Abstract: A hydrogel formulation of oxidized dextrin is reticulated with adipic acid dihydrazide, which may embody polysaccharides, proteins, nanogels, granular materials, bioactive molecules and cells for tissue regeneration and controlled drug delivery. A hydrogel can be injectable, highly biocompatible and biodegradable, for tissue regenerative applications, performing simultaneously as a vehicle e.g. for nanogels, granular materials and cells, and as controlled drug delivery systems, e.g. of hydrophobic molecules and therapeutic proteins.
