PROBLEM TO BE SOLVED: To produce a water-base wax composition, capable of sustaining antimicrobial effects for a long period without discoloring, excellent in dispersibility without sedimenting and solidifying even when allowed to stand and having antimicrobial functions. SOLUTION: This antimicrobial water-base wax composition which is the objective composition is obtained by treating the surface of at least one ceramic antimicrobial agent having 0.05-0.5μm average particle diameter with a dispersing agent having hydrophilic functional groups [e.g. isopropyl tri(n-amidoethyl- aminoethyl) titanate] in an amount of 0.1-10wt.% based on the antimicrobial agent and including the resultant material in an amount of 0.1-30wt.% based on the resin solid content of the water-based wax. Otherwise, the composition is prepared by wet pulverizing the ceramic antimicrobial agent in at least one solvent with a grinding medium having the diameter within the range of 0.1-5mm so as to provide 0.05-0.5μm average particle diameter, adding the resultant suspension of the antimicrobial agent fine particles to the water-base wax and including the fine particles in an amount of 0.1-30wt.% based on the resin solid content of the wax.
