  • a preferred range of the average particle size of the layered silicate used in the dispersion or solution is also the same as that of the layered silicate described above. As long as the average particle size of the layered silicate falls within this range, the adsorption or aggregation effect of dust is enhanced, and the stability of the dispersion when dispersing the layered silicate in a solvent can also be enhanced.
  • the dispersion or solution further comprises a deodorant component.
  • the deodorant component is also the same as that described above, and a preferred embodiment thereof is also the same as that described above.
  • the content of the deodorant component is not particularly limited. The content is preferably from 0.01 to 10% by weight, and more preferably from 0.05 to 2% by weight, from the viewpoint of exhibiting a satisfactory effect of removing odor.
