▎ 摘　　要

NOVELTY - Nano composite antibacterial agent comprises base oil, nano silver, graphene, protein, phospholipids, polysaccharides, cholesterol, vitamins, solubilizers, emulsifiers, antioxidants, polymerization inhibitors and water. USE - The antibacterial agent is useful for daily or medicinal products (claimed). ADVANTAGE - The agent selectively adsorbs, wraps, shields and negatively charged surface, controlling and preventing bacteria and viruses on negative charges on surface. The preparation method achieves uniform mixing of various raw materials thus improves stability of nano composite antibacterial agents and is is environment-friendly. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing nano composite antibacterial agent, comprising (i) mixing base oil, nano silver, graphene, protein, phospholipids, polysaccharides, cholesterol, vitamins, solubilizers, emulsifiers, antioxidants, polymerization inhibitors and water and treating by ultra-high pressure micro-jet circulation to obtain liposome mixture; (ii) homogenizing nanosilver, graphene, adsorbent, sustained release agent, a magnetic component, titanium dioxide, and zinc oxide, solubilizer, emulsifier, antioxidant, and a polymerization inhibitor with water and processing by ultra-high pressure micro-jet circulation to obtain nano particle solution; and (iii) mixing the liposome mixture and the nano particle and treating by ultra-high pressure micro-jet circulation.
