(57) [Summary] [Structure] Silica fine particles or the following general formula: [Si 8 (Mga a Li b ) O 20 OH C F 4-C ] -X Na + X (wherein 0 <a ≦ 6,0 <B ≦ 6, 4 <a + b <8, 0 A viscosity modifier for an aqueous nail varnish, which is selected from the group consisting of smectite clay minerals (for example, laponite) represented by ≦ c <4 and X = 12-2a-b. [Effects] The viscosity can be easily increased when used in an aqueous nail varnish containing core-shell type emulsion particles, for example, emulsion particles having colloidal silica as a core portion and an acrylic resin as an outer layer, and Since the viscosity is maintained for a long period of time, it is possible to provide a manicure agent having excellent product stability. |
