PROBLEM TO BE SOLVED: To provide an aqueous cosmetic which suppresses uneven spreading after application, has a good spreading properties at the time of applying powdery foundation, and improves make-up deterioration around the facial lines after 6 hours from the application of a powdery foundation.SOLUTION: The invention provides an aqueous cosmetic comprising: (A) 0.1-17 mass% of organopolysiloxane in which poly (N-acyl alkylene imine) segments having an average molecular weight of 1000-40000 consisting of repeating units mediated by alkylene group comprising a hetero atom bind at least two of silicon atoms of the organopolysiloxane segment constructing a principal chain; (B) 0.05-5 mass% of hydrophobically modified polyether urethane represented by the following general formula (5); and (C) water. The mass ratio of the component (A) and the component (B), (A)/(B) is 0.1-50. The mass ratio of the organopolysiloxane segment and the poly (N-acyl alkylene imine) segment of the ingredient (A) is 45/55 to 79/21.COPYRIGHT: (C)2015,JPO&INPIT【課題】塗布後の弾きむらを抑制し、パウダーファンデーション塗布時ののびが良好で、パウダーファンデーション塗布6時間経過後の化粧よれが改善された水性化粧料の提供。【解決手段】(A)主鎖を構成するオルガノポリシロキサンセグメントのケイ素原子の少なくとも2つに、ヘテロ原子を含むアルキレン基を介する繰り返し単位からなる平均分子量が1000~40000であるポリ(N-アシルアルキレンイミン)セグメントが結合してなるオルガノポリシロキサン0.1~17質量%、(B)下記一般式(5):で表される疎水変性ポリエーテルウレタン0.05~5質量%、及び(C)水を含有し、成分(A)及び(B)の質量割合(A)/(B)が、0.1~50である水性化粧料。成分(A)のオルガノポリシロキサンセグメントとポリ(N-アシルアルキレンイミン)セグメントの質量比が45/55~79/21である水性化粧品。【選択図】なし
