Description Color development improver Technical field

The present invention relates to a novel color formation improving agent, and more particularly to a color formation improving agent containing a pigment compound derived from radish as an active ingredient. Background art

Since ancient times, color has been used as a means of expressing emotions through sight and symbolizing authority. In particular, red is a color that reminds of active impressions such as life, passion, courage, love, and aggressiveness.In the field of cosmetics, red is the main color that colors lipsticks and other finishing cosmetics. . For example, in the case of lipsticks, even for the same red color, the finish is slightly different depending on the hue, lightness, saturation, etc. of the coloring material. Various ideas have been devised to respond to tastes. In recent years, while reflecting the women's advancement in society or suppressing the gaudiness, the colors are fresh and brilliant, and the color is as if the colors are inside in order to promote the inner fulfillment, aggressiveness and youthfulness. Cosmetics have come to be sought after.

Red coloring agents used in finishing cosmetics are roughly classified into organic synthetic pigments, natural pigments, and inorganic pigments. Recently, natural pigments are used in terms of safety and physical action. Stuff has come to be used frequently. As a natural coloring red coloring material, for example, those containing coloring compounds derived from perilla, red beet, safflower, red koji, red bean, etc. are known (for example, see Japanese Patent Application Laid-Open No. Hei 8-5942). No. 7, JP-A-10--15 Among these, the coloring compounds derived from safflower, among others, have the advantages described above, but because the color development is biased toward the purple side, such as finishing cosmetics When blended with red, there is a problem that the original emotional expression of the color red cannot be fully exhibited.

In view of such circumstances, the present invention provides a color-improving agent that improves the color-developing property by using in combination with a luminescent red-color-forming substance such as a safflower-derived coloring compound to give a fresh, vivid red color. And its use. Disclosure of the invention

In order to solve such a problem, the present inventor focused on a natural dye-based dye compound, and conducted extensive research and search. As a result, a red-light-emitting luminescent coloring material, In other words, they found that when used in combination with a coloring compound derived from safflower and the like, the color development was significantly improved, and a bright, vivid red color was exhibited. A coloring agent containing a pigment compound derived from entrails as a coloring agent and a safflower-derived coloring compound as a luminescent red coloring material is used in addition to finishing cosmetics and other general cosmetics. The present invention has been completed by confirming that the present invention can be advantageously used in a wide variety of articles requiring a vivid, vivid red color.

That is, the present invention solves the above-mentioned problems by providing a color-developing agent containing a pigment compound derived from radish as an active ingredient.

Further, the present invention solves the above-mentioned problem by providing a coloring material comprising a safflower-derived coloring compound together with a radish-derived coloring compound as a coloring-improving component.

Further, the present invention provides a cosmetic comprising a safflower-derived coloring compound, together with a radish-derived coloring compound as a coloring improvement component. This solves the above problem. BEST MODE FOR CARRYING OUT THE INVENTION

In the present invention, the term "dye compound derived from worms" refers to a dye compound or a mixture of dye compounds derived from worms, which are insects of the scale insects, and a luminescent red coloring material including a dye compound derived from safflower described below. Means that the color development can be significantly improved by coexistence. Therefore, in the present invention, any dye compound is one that is derived from radish and exerts the above-described action on a luminescent red color-forming substance such as a safflower-derived dye compound. It can be used advantageously regardless of the key, structure, composition, preparation method, etc.

Specific examples of such dye compounds include, for example, carminic acid, carminic acid aluminum lakes, carminic acid calcium lakes, carminic acid aluminum / calcium lakes, and other carminic acid lakes. Further, a mixture thereof can be mentioned, and among them, a lake is preferable in that it has a large coloring improvement ability and is stable. Such a dye compound may be prepared from a natural source or artificially synthesized by an organic chemical technique. When prepared from a natural source, the coloring compound does not necessarily have to be in isolated form, depending on the end use of the color improving agent, for example, one or more of the essential components of the coloring compound And a non-separable composition of contaminants peculiar to the source and the preparation method. When the final use of the color development improver is cosmetics, it can be obtained from the economical point of view by, for example, crushing a dried adult female female extract, extracting with water and Z or alcohol, and drying. And so-called "cochineal" and rakes thereof. In addition, The dye compound may be in a form that can be dissolved in an aqueous or non-aqueous solvent, or in a form that is substantially insoluble in such a solvent and that is supported by an insoluble substance described below. Good.

The pigment compound derived from safflower referred to in the present invention is a pigment compound or a mixture of pigment compounds obtainable from safflower, which is a herb of Asteraceae, which absorbs visible light and Z or near-ultraviolet light and has a red color. It emits fluorescent light in the area. Examples of the individual dye compounds include, for example, carsamine, which is the main luminescent red color-forming substance in Benipana, and an unseparated composition of carsamine and impurities specific to the source or preparation method, Examples include "safflower red" and "safflower extract". In addition, the coloring compound derived from safflower, like the coloring compound derived from radish, is in a form soluble in an aqueous or non-aqueous solvent, but is substantially insoluble in such a solvent. It may be in the form of being carried on. Explaining the insoluble substance, the insoluble substance that carries the pigment compound derived from radish beetle and the pigment compound derived from Z or safflower must not be limited to a specific one.For example, it is acceptable as a component of cosmetics. Any of these can be advantageously used in the present invention. Specific examples of such an insoluble substance include, for example, minerals such as talc, kaolin, myritsu (muscous mica), sericite (sericite), titanium mica, titanium oxide treated iron oxide mica titanium, calcium carbonate, Inorganic materials such as magnesium carbonate, caic anhydride, barium sulfate, titanium oxide, zinc white, bismuth oxychloride, etc., organic materials such as fish scale foil, metal stones, nylon powder, polyethylene powder, polymethyl methacrylate And synthetic products such as synthetic polymers, cellulose and silk, and other natural products and synthetic products, as well as those obtained by combining these. Among them, in terms of safety, etc. Those derived from nature are preferred. Such insoluble materials are usually Depending on the application, the particle size of the powder is in the range of 0.005 to 50 m for mineral and inorganic materials, and for polymer materials. In that case, it is adjusted in the range of 0.01 to 50 im. In order to support the pigment compound derived from radish beetle and the pigment compound derived from Z or safflower on such an insoluble substance, if necessary, for example, a hydroxide or carbonate of an alkali metal and a water-soluble aluminum salt are used. The dye compound is dissolved or dispersed in water or an organic solvent such as methanol, ethanol, propanol, isopropanol, 1,3-butylene glycol or a mixture thereof in the presence of an adhesion promoter, and the solution or After adding an appropriate amount of the insoluble substance as described above to the suspension, room temperature or a temperature higher than room temperature, for example, for 0.5 to 24 hours at 40 to 100 ° C, while stirring, if necessary. The dye compound is brought into contact with the insoluble substance. Thereafter, the insoluble substance carrying the dye compound is collected by filtration, centrifugation, etc., dried, and ground if necessary. In addition, a method of lakening a dye compound derived from radish or a dye compound derived from safflower or supporting the same on an insoluble substance is described in, for example, Japanese Patent Application Laid-Open Nos. Hei 8-59-427 and Hei 10-15. It is described in detail in Japanese Patent Publication No.

Hereinafter, embodiments of the present invention will be described based on examples. Example 1: coloring material

According to the methods described in JP-A-8-59427 and JP-A-10-1585737, cochineal (trade name) as a pigment compound derived from radish is used. "Cochineal lake", color value of 80 or more, Saneigen F ■ F ■ I Co., Ltd.) and safflower red as a pigment compound derived from Benipana (trade name “Casa Mass Thread A”, color value of 100 or more , And Saneigen-F '(manufactured by F Co., Ltd.) were uniformly supported on powdered cellulose (average particle size: 5 βm) at a weight ratio of 1: 9 to obtain a color former.

Then, a part of the coloring material thus obtained was removed, and this was further processed by Susumu Shimoyama et al., “Analytical Chemistry”, Vol. 46, No. 7, pp. 571 to 578 (19997). When the visible absorption spectrum and the fluorescence spectrum were measured by applying the three-dimensional fluorescence spectrum method described in (1), the colorant in this example had a wavelength of 380 to 5 nm. It absorbed light of 70 nm and emitted red light with a wavelength of 600 to 700 nm, and the emission maximum was observed at around 60 nm. Further, the hue, lightness, and saturation of color development of the coloring material of this example measured by the Munsell color system were 0.1 R 4.4 / 8.3.

At the same time, the visible absorption spectrum and the fluorescence spectrum were measured in the same manner as above using powdered cellulose carrying only safflower red.The product absorbed light at a wavelength of 550 nm. However, it had an emission maximum at a wavelength of 62 nm, which was significantly shorter than the coloring material of this example. By the way, the powdered cellulose loaded with only safflower red has a hue of 8.0 RP according to the Munsell color system and the freshness and vividness of the red color of the present invention. It was obviously worse.

These results indicate that the coexistence of the radish reddish coloring compound significantly improved the luminescent properties of the luminescent red coloring material, especially the safflower-derived coloring compound, and used only the safflower-derived coloring compound. This means that a vivid, vivid red color can never be obtained.

The color former of the present example, which is stable, fresh, and bright red, is extremely useful in cosmetics in general and in various articles requiring such color development. Example 2-. Color former

According to the method described in Japanese Patent Application Laid-Open No. H10-15858037, aluminum calcium lake of cochineal as a pigment compound derived from engmushi (trade name “Kochini Lake”, color value of 800) As described above, ultrafine particles (average particle system: 0.04 / m) of titanium oxide loaded with Saneigen Fff-I Co., Ltd. are described in JP-A-8-59427. Ultrafine cellulose particles carrying a red color (Veneer name: Casa Mass A, color value of 100 or more, manufactured by Saneigen F'F.I Co., Ltd.) (Average particle size: 0.1 jU m) was uniformly mixed at a weight ratio of 3: 1 to obtain a color former.
