US 12,576,023 B2 · Fermented nano-emulsifier composition and preparation method therefor

Abstract

The present invention can provide a method for preparing a fermented nano-emulsifier composition comprising a product obtained by fermenting an oil with a skin flora, and a skin-friendly composition by minimizing the contents of synthetic raw materials according to such a method. Further, it is possible to improve an emulsification power by forming a nano-emulsion in a size of nm, to be adopted to various formulations by enhancing stability of the composition, and to be easily applied to various formulations requiring a function of hypoallergenic skin due to minimization of the skin irritation.
