Description

Technical Field

[0001] The present invention relates to a cosmetic preparation. Background Art

[0002] In recent years, with the increase of hygiene awareness caused by the spread of new viral infectious diseases, the number of times of washing hands every day has continued to increase. As for the cosmetic products used when washing hands, since there are many opportunities for contact when washing hands, the hygiene of the cosmetic products themselves is required.

[0003] As a hygienic cosmetic product, for example, a pump-type package having a pump head containing an antibacterial agent has been proposed for the purpose of preventing the adhesion of bacteria due to use (see, for example, Patent Document 1). However, when the container of the existing cosmetic product including this solution contains an antibacterial agent, the container turns yellow and the color of the container is poor. In addition, when the existing cosmetic product including the above-mentioned solution is filled with a composition containing an amino alcohol or a polymer containing an acrylamide monomer, the color tone of the composition changes over time.

[0004] Therefore, there has been no provision of a cosmetic product in which the color of the container is good and the color tone of the composition filled in the cosmetic product does not change over time, and there is a strong demand for rapid development thereof at present.

Effects of the Invention

[0009] According to the present invention, it is possible to provide a cosmetic product having a good color of a container and having an excellent effect of suppressing the change in the color tone of the cosmetic composition filled therein. DETAILED DESCRIPTION

[0010] (Cosmetic products) The cosmetic product of the present invention is obtained by filling a cosmetic composition in a container containing (A1) a glass-based antimicrobial agent and (A2) at least one coloring agent selected from oxides and sulfides. It should be noted that in this specification, (A1) glass-based antibacterial agent is sometimes referred to as "(A1) component" or "(A1)", and (A2) colorant selected from at least one of oxides or sulfides is sometimes referred to as "(A2) component" or "(A2)".

[0011] <Container> The container comprises (A1) a glass-based antimicrobial agent and (A2) at least one coloring agent selected from oxides or sulfides, and may also contain other components (D1) as needed. It should be noted that, in the present specification, the “container” differs from the cosmetic product in that it is not filled with a cosmetic composition.

[0012] <<(A1) Glass-based antimicrobial agents>> The glass-based antimicrobial agent (A1) is mainly used to suppress the change in the color tone of the cosmetic composition filled in the container. By adding the glass-based antimicrobial agent to the container, the container is given antimicrobial properties, and the blackening and yellowing of the container over time can be suppressed, and the formation of bacterial biofilm (a substance called "slime" or "mud" produced in water) which is an aggregate of microbial products and bacteria can be suppressed.

[0013] The component (A1) is not particularly limited and may be appropriately selected depending on the intended purpose. From the viewpoint of enhancing the effect of suppressing the change in color tone of the cosmetic composition filled in the container, zinc-based soluble glass, silver-based soluble glass, and copper-based soluble glass are preferred, and zinc-based soluble glass is more preferred.

[0014] The content of the component (A1) is not particularly limited and may be appropriately set depending on the purpose. However, from the viewpoint of the effect of suppressing the change in the color tone of the cosmetic composition filled in the container and preventing the container from yellowing, the content is preferably 0.1% by mass to 2.4% by mass, and more preferably 0.5% by mass to 2% by mass, relative to the total mass of the container. When the content of the component (A1) is 0.1% by mass or more based on the total mass of the container, the effect of suppressing the change in color tone of the cosmetic composition filled in the container becomes good, which is preferred. When the content of the component (A1) is 2.4% by mass or less based on the total mass of the container, the container is preferably free from yellowing.

[0015] The component (A1) may be a properly synthesized substance or a commercially available product. Commercially available products of the component (A1) include, for example, ionpure (zinc-based soluble glass, manufactured by Ishizuka Glass Co., Ltd.), ionpure (silver-based soluble glass, manufactured by Ishizuka Glass Co., Ltd.), novaron VAG500 (silver-based glass-based antibacterial agent, manufactured by Toagosei Co., Ltd.), and ionpure (copper-based soluble glass, manufactured by Ishizuka Glass Co., Ltd.).

From the viewpoint of coloring of the container, the content is preferably 1.0% by mass to 7.0% by mass, and more preferably 2.0% by mass to 5.0% by mass, relative to the total mass of the container. When the content of the component (A2) is 1.0% by mass or more based on the total mass of the container, the coloring of the container becomes good, which is preferred. When the content of the component (A2) is 7.0% by mass or less based on the total mass of the container, the problem of being unable to mold a container can be solved, which is preferred.

[0019] As the component (A2), a properly synthesized substance or a commercially available product may be used. Commercially available products of the component (A2) include, for example, CR-90 (titanium oxide, manufactured by Ishihara Sangyo Co., Ltd.), ferric oxide (iron oxide, manufactured by Tetsugen Co., Ltd.), chromium oxide for grinding (chromium oxide, manufactured by Nippon Chemical Industry Co., Ltd.), zinc sulfide (manufactured by Kanto Chemical Co., Ltd.), etc.

[0020] In the present invention, the mass ratio of the content of the (A1) in the container to the content of the (A2) in the container [(A1) / (A2)] is 0.014 or more and 0.6 or less. In addition, in this specification, "the mass ratio of the content of (A1) in the container to the content of (A2) in the container [(A1) / (A2)]" may be simply referred to as "mass ratio [(A1) / (A2)]". The mass ratio [(A1) / (A2)] is preferably 0.1 or more and 0.45 or less from the viewpoint of the effect of suppressing the change in color tone of the cosmetic composition filled in the container and the effect of suppressing yellowing of the container. When the mass ratio [(A1) / (A2)] is 0.014 or more, the effect of suppressing the change in the color tone of the cosmetic composition filled in the container becomes good, which is preferred. When the mass ratio [(A1) / (A2)] is 0.6 or less, the effect of suppressing yellowing of the container becomes good, which is preferred.
