PROBLEM TO BE SOLVED: To provide a skin care preparation obtained by mixing silver ion-carrying antimicrobial zeolite with ethanol, which has remarkably improved dispersion stability of silver ion-carrying antimicrobial zeolite powder without causing discoloring and a liquid skin care preparation mixed with silver ion-carrying antimicrobial zeolite powder especially treated with an MQ resin, which prevents flocculation and discoloration of the antimicrobial zeolite powder, secures redispersibility and is stable.SOLUTION: The skin care preparation is obtained by mixing (a) 0.001-20 mass%, based on the total of the skin care preparation, of silver ion-carrying antimicrobial zeolite with (b) 50-99.6 mass%, based on the total of the skin care preparation, of ethanol, (c) 0-50 mass%, based on the total of the skin care preparation, of water and (d) 0.2-4 mass%, based on the total of the skin care preparation, of a polymer having a polyacrylic acid amide skeleton.COPYRIGHT: (C)2012,JPO&INPIT【課題】銀イオン担持抗菌性ゼオライトとエタノールを配合する皮膚外用剤において、その変色を引き起こさずに、銀イオン担持抗菌性ゼオライト粉末の分散安定性を著しく向上せしめた皮膚外用剤を提供すること。特にMQレジンで処理した銀イオン担持抗菌性ゼオライト粉末を配合した液状の皮膚外用剤において、当該抗菌性ゼオライト粉末の凝集や変色を防止し、再分散性を確保する安定な皮膚外用剤を提供すること。【解決手段】下記成分(a)~(d)を配合することを特徴とする皮膚外用剤である。(a)銀イオン担持抗菌性ゼオライトを皮膚外用剤全量に対して0.001~20質量%(b)エタノールを皮膚外用剤全量に対して50~99.6質量%(c)水を皮膚外用剤全量に対して0~50質量%(d)ポリアクリル酸アミド骨格を有する重合体を皮膚外用剤全量に対して0.2~4質量%【選択図】なし
