[0004] The present invention provides an oil-in-water emulsified cosmetic containing the following components (A), (B), (C), and (D), and the mass ratio [(B) / (A)] of the content of component (B) to component (A) is 0.2 or more and 10 or less.

[0006] (B) A highly polymerized silicone oil;

[0007] (C) A poly(meth)acrylamide compound;

[0008] (D) A hydrophobized powder. Detailed Description of the Invention

[0009] The oil-in-water emulsified cosmetic described in Patent Document 1 has insufficient effect of suppressing oiliness caused by sebum.

[0010] The present invention relates to providing an oil-in-water emulsified cosmetic having excellent ultraviolet protection effect, effect of suppressing oiliness caused by sebum, and stability over time.

[0011] The inventors of the present invention have found that an oil-in-water emulsified cosmetic obtained by combining a poly(meth)acrylamide compound, a hydrophobized powder, an ultraviolet absorber having a siloxane bond in the molecule, and a highly polymerized silicone oil in a specific mass ratio has excellent ultraviolet protection effect, effect of suppressing oiliness caused by sebum, and stability over time, and has little stickiness after coating, thus completing the present invention.

[0012] The oil-in-water emulsified cosmetic of the present invention has excellent ultraviolet protection effect, effect of suppressing oiliness caused by sebum, and stability over time. In addition, it has little stickiness after coating.

[0013] <Component (A)>

[0014] The oil-in-water emulsified cosmetic of the present invention contains (A) an ultraviolet absorber having a siloxane bond in the molecule. Here, (B) highly polymerized silicone oil sometimes separates in the oil phase, reducing the ultraviolet protection effect. However, in the present invention, by containing component (B) and component (A) in a content mass ratio [(B) / (A)] of 0.2 or more and 10 or less, excellent ultraviolet protection effect can be obtained despite containing the above-mentioned component (B).

[0015] The siloxane bond refers to the SiOSi bond. Examples of the ultraviolet absorber having a siloxane bond in the molecule include silicone ultraviolet absorbers and ultraviolet absorbers having a trisiloxane residue in the molecule.

[0016] As the silicone ultraviolet absorber, a compound obtained by substituting part or all of the methyl groups of dimethicone with diethyl 4-propynyloxybenzylidenemalonate is preferred, and examples include polysilicone-15 (dimethicone diethylbenzylidenemalonate).

[0019] In addition, the ultraviolet absorber having a siloxane bond in the molecule can be roughly classified into an ultraviolet absorber that is solid at 25°C under 1 atmosphere and an ultraviolet absorber that is liquid at 25°C under 1 atmosphere. For example, the above-mentioned polysilicone-15 is liquid at 25°C under 1 atmosphere. In addition, the above-mentioned homosalate trisiloxane is solid at 25°C under 1 atmosphere.

[0020] Furthermore, the ultraviolet absorber having a siloxane bond in the molecule can be used alone or in combination of two or more.
