Abstract: The problem to be solved by the present invention is to provide a water-in-oil-type solid cosmetic which contains an ultraviolet ray absorber, can be solidified with a wax, rarely undergoes a sweating phenomenon, and has excellent sensation upon use. A water-in-oil-type solid cosmetic is capable of being solidified with a wax, the solid cosmetic contains a continuous-phase oil that contains an organic modified silicone and can form a continuous oily phase, a wax that is compatible with the continuous-phase oil, an ultraviolet ray absorber and an aqueous phase, wherein oily phase droplets each contain the ultraviolet ray absorber and aqueous phase droplets are dispersed separately in the continuous phase oil having the wax dissolved therein.

Abstract: A low-viscosity water-in-oil cosmetic emulsion preparation gives a smooth use feeling, lightly spreads when applied, and has excellent dispersed-powder stability. The cosmetic emulsion preparation has (A) a polar oil which is liquid at 25° C. and has an IOB value exceeding 0.1, (B) a hydrocarbon oil, (C) a polyoxyalkylene; and alkyl-modified organopolysiloxane represented by general formula (I), and (D) a powder surface-treated with both an N-acylamino acid and methylpolysiloxane. (In formula (I), R represents a hydrogen atom or a C1-5 alkyl group, x is an integer of 5-50, y is an integer of 1-30, z is an integer of 20-200, a is an integer of 2-20, b is an integer of 1-5, c is an integer of 2-20, and d is an integer of 0-20.)
