PROBLEM TO BE SOLVED: To provide a composite polymer particle which is excellent in compounding stability even in a W/O emulsion type toilet article, has a high ultraviolet rays protecting effect and gives a pleasant feeling to users, to provide its production method and to provide a toilet article containing the same.
SOLUTION: The composite polymer particle is obtainable by polymerization of a vinyl monomer with a crosslinking agent, wherein the monomer contains a metal oxide which is covered with silicone and/or fluorine compounds and its average particle diameter is not more than 1 μm, and the monomer content is at least 25 pts.mass against 100 pts.mass of the sum of the total monomer and the crosslinking agent, and the solubility parameter of the monomer calculated by Fedors method is less than 8.9. Moreover, in a toilet article is contained the composite polymer particle, which contains a metal oxide covered with the silicone and/or fluorine compounds and its average particle diameter is not more than 1 μm, in an amount corresponding to 5 mass%, as a metal oxide and 1 mass% of 2-ethylhexyl 4-methoxycinnamate, and the SPF of the toilet article is at least 7. The toilet article comprises this.
