Skin lotion comprising aqueous dispersion of ultra-fine noble metal particles and method for producing the lotion

Use in cosmetic lotions a dispersion solution of super-fine noble metal particles obtained by burning a mixture gas of oxygen and hydrogen in high-pressure water and using the combustion gas to melt noble metal and thus causing super-fine noble metal particles to micro-disperse in water, wherein such production process is implemented using an apparatus for producing a cosmetic lotion that comprises a pressure-resistant container equipped with a high-pressure water tank, 'an injection nozzle for mixture gas of oxygen and hydrogen, a noble metal bar, an ignition device and a combustion chamber.
