    • PURPOSE: A method for preparing chitin/chitosan complex microparticles is provided to be applied to a functional cosmetic product and to remove side effect such as skin irritation and molecule instability. CONSTITUTION: A method for preparing multifunctional nanoparticles containing an anti-aging and UV protecting agent comprises: a step of swelling and gelling chitin in sulfuric acid or phosphoric acid and adding excessive amount of water for emulsifying; a step of filtering-washing the emulsified chitin microparticles and drying to prepare chitin microparticles; a step of dissolving chitosan in acetic acid, lactic acid, hydrochloric acid, or sulfuric acid; a step of adding surfactant to the dissolved chitosan solution; a step of drying filtration-washing-neutralizing processes; or a step of adding surfactant to the dissolved chitosan solution and binding UV protecting agent and anti-aging agent to the chitin/chitin microparticles. The UV protecting agent is p-amonobenzoic acid, benzyldimethoxybenzoylmethane, teraphthalidene dicamphor sulfonic acid, methyl anthranilate, benzophenone-3, benzophenone-2, octhyl methoxycynnamate, or octyl salicylate.
