  • Fermented nano-emulsifier composition and preparation method therefor
    Patent number: 12576023
    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.

  • METHOD FOR PREPARING FERMENTED VEGETABLE OIL BY MEANS OF SKIN FLORA, AND COSMETIC COMPOSITION COMPRISING SAME
    Publication number: 20250152500
    Abstract: The present invention relates to a cosmetic composition in which lipid fermentation metabolites are produced by fermenting vegetable oil with skin flora, and a method for producing the same. According to the present invention, lipid fermentation metabolites similar to skin lipids can be produced by fermenting vegetable oil with skin flora. Further, thereby, the skin affinity and skin barrier-protecting effect of the fermented vegetable oil can be maximized.
