The present invention relates to a makeup cosmetic capable of emitting fluorescence to provide a bright (brilliant) fluorescent color and transparent (clear) finish. More specifically, the present invention relates to a cosmetic coloring material containing a predetermined material(s), an oil-soluble dye and an oily component in combination and a makeup cosmetic containing the cosmetic coloring material.
Makeup cosmetics including lip cosmetics for coloring lips such as lipsticks and glosses, rouges (blushers) and eye shadows exert important cosmetic effects in significantly changing the physical appearance of the user. The color of a cosmetic is a key factor in choosing a cosmetic product. Recently, it has been desired to develop makeup cosmetics having a bright color and giving a transparent (clear) impression; for example, a lipstick displaying a highly bright fluorescent color has attracted attention.
Makeup cosmetics usually contain an oil base and a coloring material (coloring agent). The coloring material is responsible for producing a color when the cosmetic is applied to the lips and skin. The coloring materials to be blended in cosmetics include organic synthetic coloring agents (also called as tar colors) and inorganic pigments. The organic synthetic coloring agents are classified into dyes and organic pigments. The organic pigments are further classified into pigment coloring agents themselves and lake pigments, which are prepared by making water-soluble or sparingly-water-soluble dyes to be water insoluble (Non Patent Document 1).
Patent Document 1 discloses that if a fluorescent lame (lamé), which is prepared by adding flaky powder having at least one resin layer stained with a fluorescent dye or a fluorescent pigment, is blended in a makeup cosmetic, the fluorescent color of the resultant cosmetic is improved in uniformity and stability compared to the case in which a fluorescent dye or a fluorescent pigment is directly blended in a cosmetic.
However, it is considered that the color in appearance is determined by a pigment (Non Patent Document 1). The pigment, which is usually blended at 1 mass % or more, determines the color in appearance and also produces covering power. The cosmetic disclosed in Patent Document 1, which is prepared by adding a fluorescent lame containing a dye or pigment producing a fluorescent color to the color in appearance previously determined by a pigment, is interpreted as a makeup cosmetic for changing appearance. A dye or pigment intrinsically producing a fluorescent color is used as a material for the lame.
Patent Document 2 focuses on an oil-soluble dye for producing color of a lipstick cosmetic; however, Patent Document 2 only discloses a technique for blending perfluoropolyether in combination with an oil-soluble dye in order to solve problems, i.e., chapped lips and color change in appearance caused by dyeing of an oil-soluble dye conventionally used, but for a fluorescent color produced by the oil-soluble dye.
Patent Document 3 discloses that a makeup cosmetic (including a lipstick) containing an oil-soluble dye, which does not produce a fluorescent color when it is dissolved or dispersed alone in an oily component, in combination with a polyamide powder having a predetermined molecular weight and a predetermined particle diameter, produces a fluorescent color. However, the cosmetic containing an oil-soluble dye and a polyamide powder has a high covering power and lacks in transparency.
In short, a makeup cosmetic successfully producing a bright fluorescent color and providing transparency (clearness) has not yet been obtained up to present.
An object of the present invention is to provide a novel makeup cosmetic successfully producing a bright fluorescent color and providing transparency (clearness).
The present inventors conducted intensive studies with a view to solving the aforementioned problems and, as a result, found that a makeup cosmetic producing a bright fluorescent color and providing excellent transparency (clearness) can be obtained by blending a specific soap-base material and a specific oil-soluble dye(s) in combination. Based on the finding, the present invention was accomplished.
More specifically, the present invention provides a makeup cosmetic containing (A) at least one oil-soluble dye selected from the group consisting of Red No. 218, Red No. 223 and Orange No. 201, (B) a higher fatty acid metal salt, and (C) an oily component, wherein the makeup cosmetic may further comprise a pigment in an amount of 0.5 mass % or less; and wherein the oil-soluble dye is dissolved or dispersed in the oily component.
The present invention further provides a cosmetic coloring material to be blended in the makeup cosmetic. The cosmetic coloring material of the present invention contains the components (A), (B) and (C).
The makeup cosmetic according to the present invention can produce a bright fluorescent color based on a fluorescent dye intrinsically not producing a fluorescent color by blending a specific oil-soluble dye(s) and a specific soap-base material in combination. The makeup cosmetic according to the present invention can not only provide excellent transparency (clearness) but also produce a bright fluorescent color by suppressing the content of a pigment to a predetermined value or less.
The above and other aspects, features and advantages of the present invention will become apparent from the following description read in conjunction with the accompanying drawings, in which like reference numerals designate the same elements.

If necessary, e.g., an oil thickener (gelling agent) as mentioned above may be contained.
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.
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.
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).
Now, the present invention will be more specifically described by way of Examples; however, the present invention is not limited by these. Note that, unless otherwise specified, the content is expressed by mass % relative to the whole amount.
Lipstick cosmetics having the compositions listed in the following Table 1 and Table 2 were prepared.
In each example, lipstick cosmetics were prepared in accordance with the following two processes.
(Process 1) The components to be blended (listed in Tables) were combined, heated to 80 to 140° C., stirred/mixed, defoamed, poured in lipstick containers and cooled to 5° C.
(Process 2) Of the components listed in Tables, paraffin, microcrystalline wax, methylphenylsilicone, dye (Red No. 218) and a higher fatty acid metal salt (or other powders) were used in their whole amounts. The dye was dissolved in the oily component and the higher fatty acid metal salt or other powders were added, stirred/mixed while heating to 100 to 120° C. to prepare a cosmetic coloring material. Thereafter, the resultant cosmetic coloring material and the remaining components were mixed/stirred and defoamed while heating to 80 to 140° C., and cooled to 5° C.
The lipstick cosmetics and coloring materials of individual examples were evaluated by 10 experts (panelists) in accordance with the following criteria.
(1) Fluorescent Color
Remarkable fluorescent color is observed: 4
Fluorescent color is observed: 3
Color is produced but not a fluorescent color: 2
Color is not observed: 1
(2) Transparency (Clearness)
Remarkably transparent (clear): 4
Transparent (clear): 3
Slightly transparent (clear): 2
Not transparent (clear) (covering power is strong): 1
Evaluation results according to the above criteria were rated as follows and the rating results of individual examples are shown together in Table 1 and Table 2.
A: Total score is 35 to 40
(as to the fluorescent color, a case obtaining a total score of 35 to 37 was rated as A−; and a case obtaining a total score of 38 to 40 was rated as A+)
B: Total score is 25 to 34
C: Total score is 15 to 24
D: Total score is 10 to 14
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).
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.
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.
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.
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+”.
Other formulations of the makeup cosmetics according to the present invention will be described below. In any of the makeup cosmetics, bright fluorescent color and clearness were obtained.
Formulation 1: Lip Gloss
(Production Method)
Components 1 to 5 and 8 (each in the whole amount) were combined and stirred/mixed while heating to 100 to 120° C. to prepare a cosmetic coloring material.
