Abstract: Disclosed herein are recombinant spider silk compositions formed from a silk-based extrudate, such as stable films that adsorb to the skin, and methods for making these compositions. In some embodiments, provided herein is a method of making a silk-based emulsion, comprising: mixing a composition comprising a recombinant spider silk polypeptide powder and glycerol by applying pressure and shear force to the composition, thereby transforming the composition to an extrudate; suspending at least a portion of said extrudate in an aqueous solvent to form an aqueous extrudate suspension; and mixing said aqueous extrudate suspension into an emulsion to form said silk-based emulsion.

Abstract: The present disclosure relates to a composition for a molded body comprising a recombinant spider silk protein, and a plasticizer. Further, the present disclosure relates to a molded body comprising a recombinant spider silk protein and a plasticizer, and a process for preparing the molded body.
