A dispersion of cerium oxide according to an embodiment of the present disclosures shows excellent effects of enhancing the skin barrier, skin moisturizing and/or blocking fine dust, and a cosmetic composition comprising same. The dispersion of cerium oxide may be a combination of cerium oxide and a specific dispersion medium and as such, can exhibit effects of moisturizing the skin and blocking fine dust while strengthening the skin barrier, and a cosmetic composition comprising the dispersion of cerium oxide as an active ingredient.

The present invention relates to a cosmetic composition for skin containing a solvent A, a solvent B, and a polymer C, wherein a boiling point of the solvent A is lower than 99° C., and a distance Ra of the Hansen solubility parameter of the solvent A to water is 36 or less; a boiling point of the solvent B is 150° C. or higher, and a distance Ra of the Hansen solubility parameter of the solvent B to water is 40 or more; and the solvent B is compatible with the solvent A, and the polymer C is soluble in the solvent A but insoluble in the solvent B; and to a cosmetic coating film for skin,

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.
