Zusammenfassung: | PURPOSE: To suppress the lowering of antimicrobial activity and dental calculus- resistant activity in storage by packing an oral cavity-use composition containing a water-insoluble noncationic antimicrobial in a vessel of which contacting surface is composed of a specific solid polymer material. CONSTITUTION: By filling a vessel of which parts contacting with the composition is composed of polyfluoroethylene and polyvinyl chlorides with a composition containing water-insoluble noncationic antimicrobials, preferably halogenized diphenyl ethers substituted with hydroxyls of 1-3 and halogens (chlorine or bromine) of 1-4, particularly 2,4,4-trichloro-2-hydroxydiphenyl ether, the lowering of the activity in storage is suppressed. When a vessel consisting of a polymer reactive to the antimicrobial is used, the lowering of the activity is suppressed by containing 0.01-2wt.% of terpens and/or flavors in the composition. |
