This invention discloses a method for formulating and producing high-purity emulsion-type cosmetics, aiming to solve the problem that increasing the amount of emulsifier to ensure sufficient stability of the emulsion often leads to skin irritation. Furthermore, conventional processes result in emulsions with a wide and uneven particle size distribution, which negatively impacts the product's feel on the skin. The key technical points are: a method for formulating and producing high-purity emulsion-type cosmetics, comprising the following steps: emulsion oil phase preparation, emulsion aqueous phase preparation, nanocrystal seed preparation, emulsion preparation, dynamic pressure stirring, active microcapsule preparation, mixing and blending, and cooling and filling. This invention's method for formulating and producing high-purity emulsion-type cosmetics, through purification of oil and aqueous phase raw materials, addition of nano-silica with good compatibility with both oil and aqueous phases, dynamic stirring, and microcapsule technology, reduces the amount of emulsifier used while ensuring stability, and promotes the release and utilization rate of active ingredients.
