[Problem to be solved] A thickened composition and a cosmetic product are provided, which can be taken well through a mesh material, and can be uniformly spread when applied to the skin and can provide smoothness and silky touch. [Solution] A thickened composition for a cosmetic product including a content that is taken through a mesh material 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' of not less than 3000 Pa, which is 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 of not more than 0.2, which is 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 provided with a tight mesh material and an outer lid configured to tightly close a container body, and the thickened composition contained in the container body under the inner lid.
