PROBLEM TO BE SOLVED: To provide an oral cavity composition suppressing use feeling degradation of the oral cavity composition much containing oily ingredients, and capable of stabilizing formulations, and to provide a stabilizing method for the oral cavity composition much containing oily ingredients.SOLUTION: The oral cavity composition is provided by compounding (b) calcium hydrogenphosphate having &ge0.8 g/g oil absorbing amount, &ge1.0 ratio of oil absorption amount/water absorption amount and &le25 &mum average particle diameter to (a) an oral cavity composition containing as oily ingredients (a-1) hardly water-soluble oily active ingredients and (a-2) an oily substrate and having 2-30 mass% compounding amount of the oily ingredients. The stabilizing method for the oral cavity composition containing much oily ingredients comprises compounding (b) calcium hydrogenphosphate having &ge0.8 g/g oil absorbing amount, &ge1.0 ratio of oil absorption amount/water absorption amount and &le25 &mum average particle diameter to (a) an oral cavity composition comprising as oily ingredients (a-1) hardly water-soluble oily active ingredients and (a-2) an oily substrate and having 2-30 mass% compounding amount of the oily ingredients.COPYRIGHT: (C)2011,JPO&INPIT【課題】油性成分を多く含有する口腔用組成物の使用感低下を抑制し、製剤を安定化できる口腔用組成物、及び油性成分を多く含有する口腔用組成物の安定化方法を提供する。【解決手段】(a)油性成分として(a-1)水難溶性油状有効成分と(a-2)油性基剤とを含有し、該油性成分の配合量が2~30質量%である口腔用組成物に、(b)吸油量0.8g/g以上、吸油量/吸水量の比が1.0以上、平均粒径25μm以下のリン酸水素カルシウムを配合する。 油性成分を多く含有する口腔用組成物の安定化方法であって、(a)油性成分として(a-1)水難溶性の油状有効成分と(a-2)油性基剤とを含有し、該油性成分の配合量が2~30質量%である口腔用組成物に、(b)吸油量0.8g/g以上、吸油量/吸水量の比が1.0以上、平均粒径25μm以下のリン酸水素カルシウムを配合する。【選択図】なし
