Abstract: To provide a water-in-oil emulsified composition which highly encapsulates a water content, has high viscosity, and is excellent in emulsification stability.
The water-in-oil emulsified composition of the present disclosure comprises a dispersion medium comprising an oil content, and an oil-soluble copolymer having a monomer unit obtained from a specific hydrophilic monomer, and a monomer unit obtained from a specific hydrophobic monomer; and water droplets dispersed in the dispersion medium, wherein the oil content contains 60% by mass or more of polar oil with an IOB of 0.10 or more, and wherein the water droplets contain water and a surfactant, and the content of the water is 30% by mass or more based on the total amount of the composition.

Abstract: Provided is an oil-in-water emulsion composition which, while having a fresh feel without stickiness when used, has a skin unevenness correction effect and persistence thereof, and provides excellent smoothness, moisture and shininess, and feeling of tension. The oil-in-water emulsion composition is characterized by containing, in a specific ratio: (A) a non-emulsifying cross-linked polymethyl siloxane, which contains (a1) a dimethicone crosspolymer and (a2) a non-emulsifying cross-linked polymethyl siloxane other than a dimethicone crosspolymer; (B) an associative thickener; (C) a polyether-modified silicone; (D) a silicone oil; and (E) water in a specific ratio. The oil-in-water emulsion composition is further characterized in that the mass ratio ((a2)/(a1)) of (a2) the non-emulsifying cross-linked polymethyl siloxane other than a dimethicone crosspolymer to (a1) the dimethicone crosspolymer falls within a range of 0.1 to 2.5.
