Nanofibers comprising a water-soluble keratin polypeptide, at least one active ingredient and optionally at least one supporting polymer, wherein the nanofiber is obtained by electrospinning an aqueous solution comprising the keratin polypeptide, the active ingredient and optionally a supporting polymer, such as for example polycaprolactone, polylactic acid, polyglycolic acid and poly(lactic-co-glycolic acid); a method for preparing such nanofibers, and pharmaceutical and cosmetic formulations containing them are also described. |
