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: A thickened composition for a cosmetic product including a content that is taken through a mesh contains a fine particulate powder and a silicone crosspolymer having a structure where dimethicone is cross-linked with an organic group, and has a storage modulus G′≥3000 Pa, as measured with a rheometer under the conditions of a gap of 0.5 mm, a strain oscillation angle of 0.1%, a frequency of 1 Hz, and a temperature of 25° C. while increasing stress applied with a 25 mm φ cone plate, and a loss tangent tan δ≤0.2, as calculated as a loss modulus G″ measured under the same conditions divided by the storage modulus G′. A cosmetic product includes a container including an inner lid with a tight mesh and an outer lid for tightly closing a container body, and the thickened composition contained in the container body under the inner lid.
