Summary of the Invention

Problems to be Solved by the Invention

[0006] Powder-type deodorant cosmetics containing a large amount of powder provide a pleasant, non-sticky feel, but they have poor spreadability and do not adhere well or apply evenly, resulting in a lack of long-lasting deodorant effect.

[0007] On the other hand, stick-type deodorant cosmetics that contain a large amount of solid fat and are solidified offer good adhesion, but they do not spread well or feel sticky, resulting in insufficient uniform application. Furthermore, while increasing the amount of liquid oil instead of powder or solid fat improves spreadability, it leads to the problem of dissociation and a decrease in formulation stability.

[0008] Therefore, the present invention has been made in view of the above problems, and aims to provide an oily cosmetic composition that has good spreadability, adhesion, and uniform application properties, provides sufficient deodorant effect duration, and has high formulation stability with suppressed separation. [Means for solving the problem]

[0009] The present inventors conducted diligent studies to solve the above problems and have found that, in an oily cosmetic composition containing a deodorant component, powder, liquid oil, and powder dispersant, by blending the deodorant component and powder dispersant so that at least one predetermined component is included in a predetermined amount, and further blending the powder and liquid oil in predetermined amounts, and blending so that the total amount of the deodorant component and powder is a predetermined content, an oily cosmetic composition can be obtained that has good spreadability, adhesion, and uniform application, provides sufficient duration of deodorant effect, and has high formulation stability with suppressed separation.

[0017] According to the present invention, it is possible to provide an oily cosmetic having good elongation conformity, adhesion, and uniform coating property, sufficiently obtaining a lasting deodorant effect, and having high formulation stability with suppressed separation. [Modes for Carrying Out the Invention]

[0018] Hereinafter, embodiments of the present invention will be described in detail.

[0019] [(A) Deodorant Component] The (A) deodorant component is not particularly limited as long as it is a sweating component, deodorizing component, bactericidal component, etc. usually used in deodorants and antiperspirants. However, in the oily cosmetic of the present invention, it contains at least one or more selected from (A-1) sweating component, (A-2) bactericidal component, and (A-3) deodorizing component.

[0020] Examples of the (A-1) sweating component include aluminum salts such as aluminum chloride, potassium aluminum sulfate, aluminum sulfate, aluminum acetate, chlorohydroxyaluminum, and allantoin chlorohydroxyaluminum, and ammonium monoglycyrrhetinate, zinc paraphenolsulfonate, etc. Among them, chlorohydroxyaluminum, potassium aluminum sulfate, ammonium monoglycyrrhetinate, and zinc paraphenolsulfonate are preferable, and it is particularly preferable to contain at least one or more selected from chlorohydroxyaluminum and potassium aluminum sulfate.

If the blending amount is less than 1 mass%, a sufficient deodorant effect cannot be obtained in the produced oily cosmetic. If the blending amount exceeds 50 mass%, the absence of white residue, good finger smear resistance, and good elongation conformity in the produced oily cosmetic will deteriorate.

[0022] (A-2) Examples of the bactericidal component include glycyrrhetinic acid, isopropylmethylphenol, benzalkonium chloride, benzethonium chloride, halocarban, alkyltrimethylammonium chloride, resorcinol, chlorhexidine hydrochloride, phenol, phenoxyethanol, benzoic acid derivatives, trichlorocarbanilide, triethyl citrate, hexachlorophene, chlorhexidine gluconate, triclosan, salicylic acid, sorbic acid, lysozyme chloride, and ethylhexyl glycerin, etc. In particular, it preferably contains at least one selected from isopropylmethylphenol, glycyrrhetinic acid, and benzalkonium chloride.

[0023] (A-2) The content of the bactericidal component is 0.01 mass% or more and 2 mass% or less, preferably 0.02 mass% or more and 1 mass% or less, and more preferably 0.04 mass% or more and 0.5 mass% or less, based on the total amount of the cosmetic in terms of deodorant effect and formulation stability. If the blending amount is less than 0.01 mass%, a sufficient deodorant effect cannot be obtained in the produced oily cosmetic. If the blending amount exceeds 2 mass%, the formulation stability in the produced oily cosmetic will deteriorate.

[0024] (A-3) Examples of deodorizing components include metal-supported powders such as silver-supported zeolite and silver-supported silica, plant-derived components such as green tea extract, mulberry extract, eucalyptus extract, and rosemary extract, antibacterial fragrances such as dihydrofarnesol and phenethyl alcohol, metal salts other than the above-mentioned aluminum salts, metal oxides such as zinc oxide, diatomaceous earth, clay minerals, and activated carbon, but it is particularly preferable to include at least one selected from zinc oxide and green tea extract.

If the amount is less than 0.01% by mass, a sufficient deodorant effect cannot be obtained in the manufactured oily cosmetic. If the amount exceeds 30% by mass, the absence of white residue, ease of application, and ease of spreading and blending in the manufactured oily cosmetic will decrease.

[0026] <(B) Powder> (B) The powder is not particularly limited as long as it can be used in cosmetics or quasi-drugs, and both organic and inorganic powders can be used.

If the amount is less than 0.1% by mass, sufficient effects in terms of adhesion, smoothness and persistence after application, and formulation stability cannot be obtained. If the amount exceeds 10% by mass, the absence of white residue, ease of application, and ease of spreading and blending in the manufactured oily cosmetic will decrease.

[0030] Furthermore, the total content of (A) deodorant components and (B) powder ((A) + (B)) is preferably 10% by mass or more and 80% by mass or less, 20% by mass or more and 70% by mass or less, and more preferably 30% by mass or more and 60% by mass or less, relative to the total amount of the cosmetic. If the total amount is less than 10% by mass, sufficient effects cannot be obtained in terms of deodorant effect, adhesion, dryness and persistence after application, and formulation stability.
