The present invention relates to silver/polymer composite nanospheres and to a process for preparation thereof. More particularly, the present invention relates to silver/polymer composite nanospheres obtained by depositing silver nanoparticles on the surface of polymeric support and to a process for preparation thereof. Further, the silver/polymer composite nanospheres according to the present invention may not cause general discoloration and cohesion by colloidal silver and thereby can be used as a preservative having strong antimicrobial activity. In addition, the silver/polymer composite nanospheres according to the present invention can preserve cosmetics during a long period, not using conventional preservatives. Accordingly, the present invention relates to silver/polymer composite nanospheres to be used as a cosmetic preservative and to cosmetic compositions containing the same.
本发明涉及银/聚合物复合纳米球及其制备方法。更具体地说,本发明涉及通过在聚合物支撑物表面沉积银纳米颗粒而获得的银/聚合物复合纳米球以及其制备方法。此外,根据本发明的银/聚合物复合纳米球可能不会由胶体银引起一般变色和粘聚,因此可以用作具有强抗菌活性的防腐剂。此外,根据本发明的银/聚合物复合纳米球可以在较长时间内保护化妆品,而不使用传统的防腐剂。因此,本发明涉及用作化妆品防腐剂的银/聚合物复合纳米球,以及含有这种银/聚合物复合纳米球的化妆品组合物。
