PROBLEM TO BE SOLVED: To provide oral fluid compositions which can certainly deliver into a site, active ingredients which are insoluble or poorly water-soluble to a water-base composition and make them act.SOLUTION: The invention provides a fluid composition for compounding in an oral detergent or mouthwash. The composition contains one or more kinds of structuring agents selected from a gum type colloidal polymer, cellulose polymer, acrylate polymer, clay, and microparticles, as well as an aqueous carrier which is acceptable in a mouth, having a flow rate index of less than 0.85.COPYRIGHT: (C)2016,JPO&INPIT【課題】水ベースの組成物に不溶性又は難水溶性である有効成分を作用点に確実に送達、作用させることができる口腔用流体組成物の提供。【解決手段】口腔洗浄剤又は洗口剤に配合するための流体組成物であって、前記組成物は、ガムタイプコロイド状ポリマー、セルロースポリマー、アクリレートポリマー、クレイ及び微粒子から選択される1種以上の構造化剤;並びに口内で許容される水性担体を含み、0.85未満の流速指数を有する、流体組成物。【選択図】なし
