As the oily component which can be blended, the following examples may be mentioned; however, the oily component is not limited to these.

[0039] As a solid oily component, solid fats, waxes, hydrocarbons and higher alcohols may be mentioned. Specific examples thereof include solid fats such as Japanese wax, cocoa butter and hardened castor oil; waxes such as carnauba wax, beeswax, candelilla wax and jojoba wax; hydrocarbon waxes such as polyethylene wax, paraffin wax, ceresin and microcrystalline wax; higher alcohols such as behenyl alcohol, cetanol and batyl alcohol; and silicone wax.

[0040] Examples of a liquid oily component include liquid oils such as olive oil, avocado oil, camellia oil, macadamia nut oil, evening primrose oil, jojoba oil, rapeseed oil, egg yolk oil, sesame oil, castor oil, safflower oil, cottonseed oil, soybean oil, tea seed oil, rice bran oil and germ oil; hydrocarbon oils such as squalane and liquid paraffin; ester oils such as isocetyl isostearate, cetyl 2-ethylhexanoate, 2-heptylundecyl palmitate, diisobutyl adipate, 2-hexyldecyl sebacate, isopropyl myristate, 2-octyldodecyl oleate, diisostearyl malate, ethylene glycol di-2-ethylhexanoate, glyceride tri-2-heptylundecanoate, glyceryl diisostearate, glyceryl triisostearate, glyceryl trioctanoate, glyceryl triisopalmitate, trimethylolpropane tri-2-ethylhexanoate and pentaerythritol tetra-2-ethylhexanoate; linear silicone oils such as dimethyl polysiloxane and methylphenyl polysiloxane; cyclic silicone oils such as octamethylcyclotetrasiloxane and decamethylcyclopentasiloxane; triglycerine; and fluorine-modified oils.

[0041] In the makeup cosmetic of the present invention, in addition to the above essential components (A) to (C), other components (hereinafter referred to also as “optional components”), which are usually blended in makeup cosmetics, can be blended as long as they do not negate the effect of the invention.

[0042] Examples of the optional components include components constituting a coloring material and an oil base of a makeup cosmetic and other (optional) components.

[0043] Examples of the component constituting a coloring material include an organic synthetic coloring agent (tar color) selected from organic dyes (excluding the oil-soluble dye serving as component A) and organic pigments (including pigment dyestuff and lake); natural colorants; and inorganic pigments (color pigments such as red iron oxide, yellow iron oxide and ultramarine blue, and white pigments such as titanium dioxide and zinc oxide).

[0044] Note that, in the makeup cosmetic of the present invention, in order to produce excellent transparency (clearness), the content of a pigment (organic pigment and inorganic pigment) relative to the whole cosmetic is preferably 0.5 mass % or less and further preferably 0.4 mass % or less.

[0045] As the component constituting the oil base, an oil thickener or a gelling agent may be mentioned.

[0046] Examples of the oil thickener (gelling agent) may include dextrin fatty acid esters, glycerin fatty acid ester and organic modified clay minerals. Examples of the dextrin fatty acid ester include dextrin myristate, dextrin palmitate and dextrin (palmitate/2-ethylhexanoate). Examples of the glycerin fatty acid ester include glyceryl behenate, glyceryl octastearate and glyceryl eicosanoate.

[0047] Examples of the other (optional) components include a UV absorber, a surfactant, an antioxidant, a fragrance, a preservative, a polyhydric alcohol, a lower alcohol, an inorganic powder (including a silica powder, a extender pigment, pearlescent pigment and a functional pigment such as photochromic pigment), an organic powder, and various active components.

[0048] Note that, in the present invention, the extender pigment of which a surface is coated with a higher fatty acid metal salt serving as component B belongs to component B and is excluded from the extender pigment.

[0049] The content(s) of these optional components can be appropriately controlled depending upon e.g., form and function of the makeup cosmetic.

[0050] The makeup cosmetic of the present invention exerts a special effect that never exerted before, i.e., not only producing a highly bright fluorescent color but also providing excellent transparency (clearness). Because of this, the makeup cosmetic of the present invention is particularly suitable for point-makeup cosmetics including lip cosmetics such as a lipstick and gross, blusher and eye shadow; and especially for an oily makeup cosmetic. Note that, lip creams and makeup bases and foundations which are not primarily intended to produce a color are not included in the makeup cosmetics of the present invention.

[0051] The makeup cosmetic of the present invention can be produced by a conventional method usually used for makeup cosmetics. More specifically, the makeup cosmetic of the invention can be produced by adding the essential components (A) to (C) and an optional component(s), mixing/stirring by e.g., a homo mixer while heating, and pouring the mixture into a mold followed by cooling. Preferably, a cosmetic coloring material is produced in advance by stirring/mixing the essential components (A) to (C) while heating, and then subjected to the conventional process together with other components to produce a makeup cosmetic.

[0052] (2) Cosmetic Coloring Material

[0053] The present invention also provides a cosmetic coloring material particularly suitable for blending in the aforementioned makeup cosmetics. The cosmetic coloring material of the present invention contains an oil-soluble dye (“component A”), a higher fatty acid metal salt (“component B”) and an oily component (“component C”).

[0054] In the cosmetic coloring material of the present invention, the content of the oil-soluble dye (component A) relative to the whole coloring material is preferably 0.0002 to 10 mass % and more preferably 0.0005 to 8 mass %.

[0055] In the cosmetic coloring material of the present invention, the content of the higher fatty acid metal salt (component B) relative to the whole coloring material is preferably 0.002 to 60 mass % and more preferably 0.005 to 50 mass %.

[0056] The oily component serving as a constituent of the cosmetic coloring material of the present invention may constitute a part or whole of the oily component (component C) to be blended in the makeup cosmetic of the present invention and is preferably selected from the aforementioned oils that can dissolve or disperse the oil-soluble dye (component A).

[0057] Examples of the oily component suitably used for the coloring material of the present invention may include, but are not limited to, paraffin, squalane, isoparaffin, dimethicone, methylphenylpolysiloxane, di(isostearyl/phytosteryl) dilinoleate dimer, phytosteryl/behenyl dilinoleate dimer, phytosteryl/octyldodecyl lauroyl glutamate, glyceryl tri2-ethylhexanoate, glyceryl triisostearate, glyceryl tri(hydrogenated rosin/isostearate), diisostearyl malate, pentaerythrityl tetraethylhexanoate, dipentaerythrityl hexahydroxystearate and polyglyceryl-2 triisostearate.

[0058] In the cosmetic coloring material of the present invention, the content of the oily component relative to the whole coloring material is preferably 30 to 99.9978 mass % and more preferably 42 to 99.9945 mass %.

[0059] If necessary, e.g., an oil thickener (gelling agent) as mentioned above may be contained.

[0060] The cosmetic coloring material of the present invention is preferably contained at 10 to 60 mass %, and preferably 20 to 50 mass % in the makeup cosmetic producing a fluorescent color to which the cosmetic coloring material is added.

[0061] The coloring material of the present invention can be produced by, for example, dissolving or dispersing an oil-soluble dye (component A) in an oily component (component C), adding a higher fatty acid metal salt (component B) to the mixture and stirring/mixing the mixture while heating. The heating temperature preferably falls within the range of 80° C. to 140° C., more preferably 90° C. to 130° C. and further preferably 100° C. to 120° C.

[0062] In the coloring material and makeup cosmetic containing the coloring material of the present invention, an oil-soluble dye (component A) is present in an oily component (component C) in the state of being directly dissolved or dispersed, and can be clearly distinguished from a coloring material and a cosmetic containing, e.g., an oil-soluble dye carried on a solid carrier (e.g., solid particle).

[0085] The cosmetic coloring materials of Examples 1 to 6 containing a higher fatty acid metal salt and prepared in accordance with Process 2 produced bright fluorescent colors and had clearness (evaluation of fluorescent color: A+); however, the coloring material of Comparative Example 1 containing a nylon powder (nylon SP-500, manufactured by Toray Industries Inc., molecular weight: 10,000 to 100,000, particle size: 10 □m or less, spherical powder) described in Patent Document 3 produced pink fluorescent color but poor, and hiding power was too strong to obtain transparency (clearness) (evaluation of fluorescent color: B). The cosmetic coloring materials of Comparative Examples 2 to 4 containing a higher fatty acid, which is solid at normal temperature, or a higher alcohol in place of a higher fatty acid metal salt failed to even produce a color (evaluation of fluorescent color: C).

[0086] As is apparent from the results shown in Table 1, in the makeup cosmetics of Examples 1 to 6 containing a specific oil-soluble dye (component A) and a higher fatty acid metal salt (component B), a bright fluorescent color was observed regardless of the process and transparency (clearness) of the cosmetics was excellent. Note that, the fluorescent colors in the cases where makeup cosmetics were produced in accordance with Process 2 were brighter.

[0087] In contrast, in the makeup cosmetics of Comparative Examples 1 to 4 containing another powder such as a nylon powder in place of a higher fatty acid salt and produced in accordance with either of Process 1 and Process 2, the fluorescent color produced was poor or no fluorescent color was produced, and no transparency (clearness) was obtained. In the makeup cosmetics of Comparative Example 5 containing more than 0.5 mass % of an organic pigment (Red No. 202), neither transparency (clearness) nor fluorescent color were obtained.

[0088] Other formulations (Examples 7 to 11) of the makeup cosmetic (lipstick) of the present invention will be described below. In any of Examples, a highly bright fluorescent color and transparency (clearness) were obtained. The evaluation results in Table are based on the aforementioned criteria.

[0089] Note that, the fluorescent colors of the makeup cosmetics produced in accordance with Process 1 (conventional method) were rated as “A−”; whereas the fluorescent colors of the makeup cosmetics produced in accordance with Process 2 were rated as “A+”.
