Detalhes bibliográficos
Resumo:The present invention describes micellar protein formulations for the controlled release of active ingredients, and method for preparing the same. The invention describes a new micelle composition for use in pharmaceuticals, cosmetics and detergents. In particular, it describes micelle formation formulations that comprise: an aqueous phase containing a protein or a natural or synthetic peptide; a lipophilic phase containing a hydrophobic compound; an adjuvant dissolved in the aqueous phase to regulate the size and stability of the micelles; the size of the micelles varying from 30 to 5000 nm, preferably from 30 to 100 nm, wherein the micelles can be obtained by two different methods, namely using ultrasound or a high-pressure homogeniser. The preparation method involves two distinct phases: an aqueous phase and a lipophilic phase. The aqueous phase can be water or any buffer that is best suitable for a given use, such as an aqueous solution of bovine serum albumen (BSA); human serum albumen (HSA); silk fibroin or a polypeptide fibroin.
