PROBLEM TO BE SOLVED: To prepare a manicure material excellent in such a viewpoint as easiness to be applied, extensibility in applying, etc., a feeling in using and scarceness in change with time, by including composite powder comprising poly (organosiloxane). SOLUTION: This manicure material is prepared by including (pref. 0. 01-20 wt.%) composite powder comprising various kinds of poly(organosiloxane). It is pref. that the composite powder is prepared by the following steps: (1) adding a catalyst to an oil-based 0/W emulsion containing (i) a vinyl group- containing poly(organosiloxane) and (ii) a poly organohydrogensiloxane to cause curing reaction and to produce aqueous dispersion of the finely divided particle of spherical silicone rubber cured product; (2) adding an alkaline substance or an alkaline aqueous solution, and organotrialkoxysilane to the dispersion so as to cause hydrolysis and condensation curing reaction and then drying, and is finely divided particle with an average particle diameter of 0.1-100μm of spherical silicone rubber cured product covered with poly organosilsesquioxane.
