Description

The present invention relates to solid cosmetics.

Solid cosmetics are cosmetics that are solid at room temperature. Solid cosmetics are used as cosmetics by applying them to the skin and hair. For example, stick-shaped lipsticks, glosses, stick foundations, pencil-type cosmetics, hair sticks, lip balms filled in containers, and foundations. Etc. are known.

Solid cosmetics are required to maintain their dosage form during storage, to have a comfortable application that melts when applied, to spread the cosmetics well, and to be able to apply the cosmetics evenly to the application site (hereinafter, "at the time of application". Usability "). Further, it is required to impart desired effects such as gloss, texture, suppleness, and moisture of skin and hair to which solid cosmetics are applied (hereinafter, referred to as "aesthetic effect"). In order to satisfy such characteristics, selection of solid wax and liquid oil as a base, adjustment of blending ratio, and various additives have been studied for solid cosmetics. For example, solid wax must be sufficiently blended to maintain the dosage form of the product, but if the solid wax is blended in a large amount, the usability and aesthetic effect at the time of application deteriorate. Since these effects vary greatly depending on the selection and blending amount of solid wax and liquid oil, various combinations and blending amounts of solid wax and liquid oil have been studied in the development of solid cosmetics (for example, Patent Documents 1 to 3). ).

Japanese Unexamined Patent Publication No. 2006-052155 Japanese Unexamined Patent Publication No. 2007-045711 Japanese Unexamined Patent Publication No. 2015-174844

The present invention has been made by paying attention to the above circumstances, and an object of the present invention is to provide a solid cosmetic that satisfies the usability and aesthetic effect at the time of application. The present invention also provides a solid cosmetic having a sustainability of the aesthetic effect of the solid cosmetic (hereinafter referred to as "sustainable aesthetic effect") in addition to these effects.

The solid cosmetics of the present invention that have solved the above problems include [1] (A) selecin, (B) synthetic wax, and (C) difatty acid glyceryl having an IOB value of 0.18 to 0.45. / Or has a gist to contain the trifatty acid glyceryl.

A preferred embodiment of the solid cosmetic of the present invention is [2] the mass ratio [(A): (B)] of the component (A) to the component (B) is 9: 1 to 1: 8. 1] The solid cosmetic according to the above.

Another preferred embodiment of the solid cosmetic of the present invention is [3] the content of the component (A) contained in the solid cosmetic is 1 to 9% by mass, and the content of the component (B) is 1 to 10% by mass. The solid cosmetic according to the above [1] or [2], wherein the content of the component (C) is 10 to 70% by mass.

Another preferred embodiment of the solid cosmetic of the present invention is [4] any of the above [1] to [3] further containing (D) dimer dilinoleic acid ester and / or (E) propanediol diisostearate. It is a solid cosmetic described in propane.

The present invention also includes the solid cosmetic according to any one of the above [1] to [4], which is used by applying the solid cosmetic to the palm and then to the hair or skin.

According to the present invention, it is possible to provide a solid cosmetic that satisfies the usability and aesthetic effect at the time of application. Further, according to the present invention, it is possible to provide a solid cosmetic having an excellent long-lasting aesthetic effect.

In recent years, not only application of solid cosmetics to the skin such as lips and cheeks, but also application to hair as a hair stick has been studied. Therefore, the present inventors investigated whether the composition of the solid cosmetics provided for the conventional skin could be diverted to the hair. However, the conditions of use for hair were stricter than those for skin, and the effect was not sufficient. For example, in the case of hair, unlike lipstick, a colorant such as a pigment is not added, so that the additive cannot be expected to improve the aesthetic effect. In addition, hair is required to have a cohesiveness that is not considered for skin use. Due to such a difference, even if the solid cosmetics conventionally studied for skin were diverted to hair as they were, the usability and aesthetic effect at the time of application could not be satisfied. Further, it is desired that the frequency of reapplying the cosmetic is less on the hair than on the skin such as the lips, and that the aesthetic effect is maintained for a long time by one application.

As a result of intensive research to solve these problems, the present inventors have combined a specific solid wax and a specific liquid oil to make a solid cosmetic suitable not only for the skin but also for the hair. Specifically, they have invented a solid cosmetic that is excellent in usability at the time of application and aesthetic effect, and preferably further excellent in aesthetic effect sustainability.

The solid cosmetic of the present invention that has solved the above problems contains the following components (A) to (C) as essential components.
(A) Ingredient: Celesin (B) Ingredient: Synthetic Wax (C) Ingredient: Difatty acid glyceryl having an IOB value of 0.18 to 0.45 and / or trifatty acid glyceryl

The solid cosmetic of the present invention exerts the above-mentioned effect by using the above-mentioned three components as essential components. Celesin is a hydrocarbon wax derived from a mineral (ozokelite), and has properties such as higher viscosity, hardness, and melting point than wax obtained by refining petroleum such as paraffin and wax derived from natural plants. However, even if only selecine was used as the solid wax, there was no difference in the effect as compared with other solid waxes such as paraffin. In addition, there was no difference in the effect when selecine was combined with other solid waxes. However, when (A) selecin and (B) synthetic wax were used in combination and (C) a specific liquid oil was further combined, the synergistic effect of these significantly improved the usability and aesthetic effect at the time of application, further aesthetically pleasing. The sustainability of the effect was also improved. That is, in the present invention, only when the specific ingredients (A) to (C) are used as essential ingredients, a feeling of use at the time of application, an aesthetic effect, and its durability, which cannot be obtained by conventional solid cosmetics, can be obtained. .. In particular, the solid cosmetics of the present invention not only obtain the above-mentioned effects on hair, which cannot be obtained by conventional solid cosmetics, but also obtain the effects on the skin such as lips. Hereinafter, each component of the solid cosmetic of the present invention will be described in detail.

Component (A): Celesin Celesin is a hydrocarbon wax obtained by purifying ozokerite (mineral) and is an oily component that is solid at room temperature. In the present invention, by using selecin in combination with the components (B) and (C) described later, the feeling of use at the time of application, the aesthetic effect, and the durability of the aesthetic effect can be remarkably improved. In the present invention, selecin for various cosmetics can be used, preferably selecin having a melting point of 60 ° C. or higher, more preferably 70 ° C. or higher. Examples of commercially available products include, but are not limited to, CERESIN # 810 (manufactured by Nikko Rika), CERESIN # 820 (manufactured by Nikko Rika), and CERESIN C (manufactured by Nikko Rika). One type or a combination of two or more types of celesin can be used.

By containing selecin, which is the component (A), together with the component (B) and the component (C), it is possible to suppress the softening of the solid cosmetics, contribute to the shape retention of the dosage form, and improve the above-mentioned various effects. On the other hand, if the content of selecin is too large, the feeling of use at the time of application may be deteriorated, such as the spread and comfort of the solid cosmetic being applied, and the above-mentioned various effects may be deteriorated. From this point of view, the content of selecin (total amount when two or more kinds are used in combination) is preferably 1% by mass or more, more preferably 2% by mass or more, and further, with respect to the total amount of solid cosmetics (100% by mass). It is preferably 4% by mass or more, preferably 9% by mass or less, more preferably 7% by mass or less, and further preferably 5.5% by mass or less.
