Embodiment approach
[0018] "Filling energy" or "filling power" in this specification means the ability of a sponge to be filled with a cosmetic composition, which can be represented by the time required to fill a sponge with a predetermined amount of cosmetic composition.
[0019] In this specification, "oil absorption" means the amount of oil required to form a hard dough state after the UV blocking agent and oil are combined, and can be expressed by the mass (g) of oil relative to 1 g of the UV blocking agent.
[0020] Hereinafter, the present invention will be described in more detail.
[0021] One embodiment of the present invention provides a cosmetic comprising: a cosmetic composition for ultraviolet shielding containing spherical (sphere) titanium dioxide fine particles, and a carrier including a sponge impregnated with the cosmetic composition for ultraviolet shielding.
[0022] According to one embodiment, the spherical titanium dioxide particles may have a central volume particle diamet...
Embodiment 1 and comparative example 1、2
[0050] A cosmetic composition for ultraviolet shielding was prepared by a conventional method in the art according to the composition shown in Table 1 below. Specifically, the following ultraviolet shielding agent, oily component, and surfactant are mixed and stirred uniformly at room temperature, and then the thickener described below is mixed and stirred uniformly. Then, mix the paint and stir evenly. In a separate mixer, mix the following aqueous ingredients and stir at room temperature to completely dissolve. The uniformly stirred water-based ingredients are gradually put into the mixture including the prepared oil phase ingredients and emulsified by using a homogenizer. Thereafter, skin care ingredients, fragrances, etc. were added and cooled to obtain W / O UV-shielding cosmetic composition Example 1, Comparative Examples 1 and 2, respectively.

Embodiment 2、3 and comparative example 3、4
[0082] According to the composition in Table 5 below, a cosmetic composition for ultraviolet shielding was prepared by a conventional method in the art. Specifically, after the following ultraviolet shielding agent, oily component and surfactant are mixed and stirred uniformly at room temperature, the following thickener is mixed therein and stirred uniformly. Then, mix the pigment and powder and stir well. In a separate mixer the following aqueous ingredients were mixed and stirred at room temperature to dissolve completely. The uniformly stirred water-based component is slowly added to the prepared mixture containing the oil-based component, and then emulsified with a homogenizer. Thereafter, this was cooled to obtain W / O ultraviolet ray shielding cosmetic compositions Examples 2 and 3 and Comparative Examples 3 and 4, respectively.
