Description

  The present invention relates to a multicolor oil-based solid cosmetic, and more particularly, while having different color portions that give color to the composition, the color does not substantially affect the applied color when applied. The present invention relates to a multicolor oil-based solid cosmetic.

  Makeup cosmetics such as lipstick, eye color, and cheek color have a cosmetic effect that highlights the site of use by coloring. Those having various colors have been developed according to the intention of the user, and those having many colors are provided.

  In recent years, cosmetics having different color tones have been provided in molded products. For example, multi-color solid cosmetics are manufactured by supplying different bulks to one discharge nozzle and filling it with vibration. A method is known (Patent Document 1). However, this is a radial multi-colored pattern with an ambiguous boundary and does not give a strong impact. Moreover, the application color after application | coating is a thing with two colors mixed, and there exists a problem that selection and use of cosmetics are difficult.

  Patent Document 2 discloses a multicolor solid cosmetic having a viscosity at the time of heat filling of 100 cst or more. However, the technique disclosed in this document is a technique that fills multiple colors without providing a partition, and does not touch bar-shaped cosmetics. And this thing also has the problem that the application color after application | coating is a thing with which two colors were mixed similarly to patent document 1, and selection and use of cosmetics are difficult.

  In makeup cosmetics such as oil-based solid cosmetics, multi-colored cosmetics are more conspicuous in appearance as the color difference between each is larger, and the visual effect that attracts consumers is higher. Oil-based solid cosmetics using a plurality of colors are preferable. However, on the other hand, when selecting a cosmetic, it is common for a consumer to predict and purchase an application color based on the appearance color, and therefore, the application color when actually used is mixed with multiple colors. It is inconvenient that it becomes color and is different from previous expectations. Accordingly, there is a need for a multicolored oil-based solid cosmetic that has the appearance color of a certain portion and the expected coating color substantially the same.

JP 2004-002207 A JP 2002-097112 A

  Accordingly, an object of the present invention is to provide a multicolor oil-based solid cosmetic that can easily select an application color desired by a consumer while being visually appealing to the consumer.

  As a result of earnest research on the multicolor oil-based solid cosmetics, in particular, the rod-shaped multicolor oil-based solid cosmetics, in order to solve the above-mentioned problems, the present inventor has determined that the composition of a plurality of parts is applied to the skin as an application color. If the parts are colored and the parts that do not substantially affect the coating color are prepared, and these are clearly separated structures, the appearance color of the main part is almost the same as the coating color. The inventors found that a cosmetic can be obtained and completed the present invention.

  That is, the present invention is an oil-based solid cosmetic comprising a colored first partial composition exhibiting a coating color and a colored second partial composition exhibiting an appearance color sandwiched therebetween, The mass ratio of the first partial composition and the second partial composition is 9: 1 to 7: 3, and the degree of concealment when the first partial composition is applied and the second partial composition It is a multicolor oil-based solid cosmetic characterized in that the difference in concealment degree when applied is 15 or more.

  Since the multicolor oil-based solid cosmetic of the present invention is a multicolor of two or more colors with clearly different appearances, it has high aesthetics and attracts the attention of consumers. Moreover, when applied to the skin or the like, substantially only the appearance color of the first partial composition is developed, so that the application color at the time of application is known by the appearance color, and it is easy for consumers to purchase.

  In addition, when the first partial composition and the second partial composition have the same oil component composition, their adhesiveness or adhesion is very good, so the stability and strength are high, and the quality as a molded product. Is stable.

It is drawing (photograph) which shows the external appearance of the polychromatic oil-based solid cosmetics of this invention. In the drawing, the different color part on the right side is sandwiched between other application color parts.

  The multicolor oil-based solid cosmetic of the present invention comprises a first partial composition (hereinafter sometimes referred to as “first part”) that exhibits an application color (coloring color) by applying it to the skin, It consists of a colored second partial composition (hereinafter referred to as “second part”) that exhibits (accent color).

  The first part and the second part have a mass ratio of 9: 1 to 7: 3, and the boundary between them is clearly distinguishable. The structure is such that the second part is sandwiched between the first part like the first part / second part / first part. In this sandwiched state, as shown in FIG. 1, even if the second part is sandwiched between sandwiches, the second part has a columnar shape such as a quadrangular column, a cylinder, or a polygonal column in the first part. It may be present.

  In addition, the sandwiched second part must always be at least on the application surface of the multicolor oil-based solid cosmetic, and the area ratio of the first part and the second part on the application surface is 9: It is preferably in the range of 1-7: 3. Within this range, a visual effect is obtained, and it is advantageous to obtain a coating color substantially the same as that of the first portion.

The degree of concealment when the first part and the second part are applied needs to be greater in the first part and 15 or more than the second part. The concealment degree is a numerical value measured as follows. That is, L ^* a ^* b ^* when the heat-dissolved first part and the second part were applied to a hiding power test paper having a white part and a black part with an 8 mil doctor blade and the black part was used as a back ^. The coating color was measured by measuring the value and each L ^* a ^* b ^* value when the white part was the back, and when the white part of the first part was the back and when the black part was the back From the colorimetric values, the color difference (ΔE _B-W (a)) of the first part (a) is calculated from the colorimetric values when the white part of the second part (b) is set as the background and the black part is set as the background. The color difference (ΔE _B−W (b)) of the second part is obtained. Next, the obtained color difference between the first part and the second part is set as the degree of concealment, and the difference (ΔE _B−W (a) −ΔE _B−W (b)) is calculated, and this is set as the difference in the degree of concealment.

  The first part and the second part of the present invention are both prepared by blending the necessary pigments or the like with the oily component (base), but the oily component depends on the properties after coating required for them. In other components, the composition is greatly different.

  That is, since the first part exhibits an application color when applied to the skin, the first part may have the same composition as the multicolor oil-based solid cosmetic intended for normal coloring. Therefore, it can be prepared by adding a pigment, a concealing agent, or the like of a color to be a desired coating color to the oil component.

On the other hand, when the second part is a multicolor oil-based solid cosmetic, it is desirable that the applied color is not substantially affected when applied to the skin, although it is a clear appearance color (accent color). Therefore, it is necessary to add a pigment having a desired color, but it is not preferable to add a pigment having a very strong color because it affects the coating color of the first part. Further, if the first part and the second part have different appearance colors, the visual effect is high. Specifically, the appearance color of the second part is preferably 13 or less as the a ^* value in the L ^* a ^* b ^* color system. In addition, the second portion does not need to be a single layer, and the second portion that satisfies the above conditions can be a multilayer.

  As an example of the combination of the first part and the second part having the above-described relationship, as the first part, 2% by mass (hereinafter simply referred to as “%”) of a pigment selected from titanium oxide, an organic pigment and iron oxide having a concealing property. The combination which uses what contains the above, and uses the said pigment in the range of 0.05-1.5% can be mentioned as a 2nd part.

  Further, the first part and the second part preferably have a rheometer hardness value of 250 to 480 g, and the difference between these hardness values is preferably within 200 g. In addition, the measurement of the hardness value with a rheometer is, for example, a value when a 2 mm penetration is made at a speed of 6 cm / min using a rheometer manufactured by FUDO, using a 3 mmΦ adapter at a measurement temperature of 30 ° C. and a range of 500 g. And measure as follows.

  Next, an example of a method for producing the multicolor oil-based solid cosmetic of the present invention using the first part and the second part obtained as described above will be described.

  In the multicolor oil-based solid cosmetic of the present invention, a mold that separates the first part and the second part is used in order to clearly show the boundary between the first part and the second part. That is, first, a removable mold is attached to a mold for preparing a solid cosmetic. At the time of this attachment, it is necessary to attach the space for the first part that is outside in the solid cosmetic and the space for the second part that is sandwiched so that the volume ratio thereof is 9: 1 to 7: 3.

  Next, the melted first portion is filled into the outer first portion space, and then allowed to cool to solidify it. After solidification, when the mold is removed, a cavity is formed at the center. The cavity is filled with the dissolved second portion and allowed to cool to solidify. And then, a multicolor oil-based solid cosmetic can be obtained by taking out the solid cosmetic from the mold. In addition, when making a 2nd part into a multilayer, what is necessary is just to utilize the type | mold which produces | generates the cavity according to it.

  Therefore, as an example of the embodiment of the method for producing the multicolor oil-based solid cosmetic of the present invention, the removable mold is sandwiched between the outer space for the first partial composition in the mold for preparing the solid cosmetic. The second partial composition space is attached so that the volume ratio thereof is 9: 1 to 7: 3, and the colored first partial composition dissolved in the outer first partial composition space is filled. Then, after solidifying it, the mold is removed, and then the formed cavity is filled with the dissolved colored second partial composition, which is then solidified and then solidified from within the mold. A method of taking out the mold cosmetic can be mentioned.

  The polychromatic oily solid cosmetic thus obtained is preferably a stick cosmetic, and particularly preferably a lip cosmetic such as lipstick or lip balm.

  While the multi-color oil-based solid cosmetic of the present invention described above has an appearance color (accent color) that is visually appealing to the consumer as the second part, the application color is only the first part, The reason why the application color desired by the user can be easily selected is as follows.

  That is, since the second portion is sandwiched between the first portions, the first portion is finally applied regardless of which portion is applied to the skin. And since the concealment degree of the 1st part is remarkably large compared with the 2nd part, the apply | coated 2nd part is easily concealed and does not affect an external appearance.

  EXAMPLES Next, although an Example is given and this invention is demonstrated in more detail, this invention is not restrict | limited at all by these Examples.
