SOAP CONTAINING SILVER-SILICA NANOCOMPOSITE PARTICLES, WITHOUT DISPERSANT AND PREPARATION METHOD THEREOF

摘要

PURPOSE: A soap containing silver-silica nanocomposite particles and its preparation method are provided, to obtain an antibacterial effect, a deodorizing effect and a far infrared ray-emitting property and to allow a soap to be prepared without the addition of a dispersant. CONSTITUTION: The method comprises the steps of soaking a silver electrode and an aluminum electrode in a silica colloid water-dispersive solution so as to allow the two electrodes to be separated; and adding a dispersion solution of silver-silica nanocomposite particles obtained by applying (+) current to the silver electrode and (-) current to the aluminum electrode to electrolyze the solution. Preferably, the amount of the dispersion solution of silver-silica nanocomposite particles is 0.1-10 wt% based on the total weight of a soap; and the silver-silica nanocomposite particles comprise silica particles of 1-50 nm bonded with aluminum particles and silver particles of 1-3 nm.
