The preparation method comprises the following steps: dissolving keratin polypeptide in an alkaline aqueous solution, dropwise adding fatty acyl chloride at 4-10 DEG C, maintaining the pH value of a reaction system at 9-11, and carrying out a stirring reaction to obtain a reaction crude product; and acidifying the reaction crude product until the pH is equal to 2-4, extracting with an organic solvent to remove byproducts, adjusting the water phase to be alkaline, and drying and washing to obtain the polypeptide surfactant. The polypeptide surfactant with D-phase emulsifying capacity prepared by the invention can emulsify grease, such as high-viscosity silicone oil, volatile oil, mineral oil and the like, which are difficult to emulsify under conventional conditions, and a stable nano-emulsion is obtained. The nano-emulsion is small in particle size, high in stability and not prone to demulsification.
