Description

Technical Field

[0001] The present invention relates to skin cosmetics.

Background Art

[0002] Skin cosmetics are required to have actual effects on the skin, such as keeping the skin smooth. On the other hand, the feel and usability of skin cosmetics are also important factors for consumers. Although a skin cosmetic that is excellent in both effects and usability is desired, when a high concentration of a moisturizing component is used to obtain a certain level of moisturizing effect, the feel derived from the moisturizing component remains on the skin, resulting in inferior usability. Conversely, there are components in skin cosmetics with a reduced amount of moisturizing component that have a trade-off in that they have good usability but inferior moisturizing power.

[0003] For example, glucosylceramide can be mentioned as a natural-derived component with excellent moisturizing effects. Glucosylceramide is a type of sphingolipid and has been attracting attention as a component with various effects, and is a component widely used in cosmetics. It is known to have moisturizing effects, elasticity retention effects, improvement effects on atopic dermatitis, etc. In addition, reports have also been made that it has whitening effects and a function of suppressing melanin production (Patent Documents 1 and 2). It has also been reported that it has a function of enhancing and maintaining the water retention ability of the skin in combination with cholesterol, fatty acids, and water-soluble polymers (Patent Document 3).

Summary of the Invention

Problems to be Solved by the Invention

[0005] However, when glucosylceramide is incorporated into cosmetics, precipitation or sedimentation due to glucosylceramide occurs over time, making it difficult to incorporate it into cosmetics in large amounts. Therefore, a method that does not cause precipitation or sedimentation due to glucosylceramide and can fully utilize the moisturizing function of glucosylceramide is desired. In addition, although glucosylceramide provides a moisturizing effect to the skin, another issue is that the effect does not last long over time.

[0006] The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a skin cosmetic that is non-sticky and has a smooth feel when used, moisturizes the skin, and has an excellent moisturizing effect. [Means for solving the problem]

[0007] The present inventors have conducted intensive research to solve the above problems, and as a result have discovered a skin cosmetic which is non-sticky and smooth to use, moisturizes the skin, and has an excellent moisturizing sustaining effect, by combining one or more of glucosylceramide, hyaluronic acid and its salts, water-soluble collagen, and hydrolyzed collagen, two or more types of polyethylene glycols having an average degree of polymerization of 20 to 400, and diphenylsiloxyphenyl trimethicone, and have thus completed the present invention.

[0008] Skin cosmetics include: Contains the following (A) to (D): With respect to the total mass of the skin cosmetic, the blending amount of component (A) is from 0.00001 to 1.0 mass%, the blending amount of component (B) is from 0.0001 to 3.0 mass%, the blending amount of component (C) is from 0.05 to 12.0 mass%, and the blending amount of component (D) is from 0.01 to 8.0 mass%. (A) Glucosylceramide (B) One or more of hyaluronic acid and its salts, water-soluble collagen, and hydrolyzed collagen (C) Two or more types of polyethylene glycol with an average polymerization degree of 20 to 400 (D) Diphenylsiloxyphenyl trimethicone Effect of the Invention

[0009] According to the present invention, it is possible to provide a skin cosmetic which is non-sticky, has a smooth feel when used, moisturizes the skin, and has an excellent moisturizing effect. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] The skin cosmetic of the present invention contains (A) glucosylceramide, (B) one or more of hyaluronic acid and its salts, water-soluble collagen, and hydrolyzed collagen, (C) two or more polyethylene glycols having an average degree of polymerization of 20 to 400, and (D) diphenylsiloxyphenyl trimethicone, which are described in detail below.

[0011] <(A) Glucosylceramide> The component (A) used in the skin cosmetic composition according to this embodiment is glucosylceramide. Glucosylceramide is a type of sphingoglycolipid and is derived from plants such as rice, oryza sativa, wheat, maitake mushroom, soybean, and konjac, and can be obtained from the leaves, stems, fruits, roots, etc. of these plants, but is not limited thereto.

[0012] These ingredients are available as commercially available cosmetic ingredients, such as "Water-Soluble Ceramide RC (manufactured by Ichimaru Pharcos Co., Ltd.)," "Oryza Ceramide-LC," "Oryza Ceramide-LC0.8," "Oryza Ceramide-PC," and "Oryza Ceramide-WSPC" (all manufactured by Oryza Oil & Fat Chemical Co., Ltd.).

[0013] The blending amount of the (A) component used in the skin cosmetic according to this embodiment is 0.00001% by mass or more and 1% by mass or less of the total mass of the skin cosmetic. From the viewpoint of usability, the blending amount of the (A) component is preferably 0.00005% by mass or more and 0.05% by mass or less, more preferably 0.0001% by mass or more and 0.01% by mass or less. If the blending amount of the (A) component is 0.00001% by mass or more, a sufficient moisturizing effect can be obtained. On the other hand, if the blending amount of the (A) component is 1% by mass or less, good stability over time can be obtained and stickiness can be suppressed.

[0014] Glucosylceramide alone provides a moisturizing effect, but adding glucosylceramide to component (B) described below synergistically improves the moisturizing effect.

[0015] <(B) One or more of hyaluronic acid and its salts, water-soluble collagen, and hydrolyzed collagen> The component (B) used in the skin cosmetic according to this embodiment is one or more of hyaluronic acid and its salts, water-soluble collagen, and hydrolyzed collagen. There are no particular limitations on the hyaluronic acid and collagen, and they may be of animal origin, microbial origin, or synthetic origin. Furthermore, when the hyaluronic acid and collagen are of natural origin, there are no particular limitations on the extraction method or purification treatment method. Examples of hyaluronic acid used in the skin cosmetic according to this embodiment include hyaluronic acid obtained from umbilical cord, rooster comb, animal skin, eye glass strip, hyaluronic acid obtained by subjecting microbial cultures to extraction treatment, chemically or enzymatically synthesized hyaluronic acid, and the like. can also be used. The molecular weight of hyaluronic acid is usually 100,000 to 3,000,000, but is not limited thereto. The salt of hyaluronic acid is not particularly limited, but is preferably a food or pharmaceutical acceptable salt, for example, sodium salt, potassium salt, calcium salt, zinc salt, magnesium salt, ammonium salt, etc. In particular, sodium salt is preferred because it is highly safe when applied to the skin and penetrates into the epidermis. In addition, collagen may be obtained from the skin, swim bladder, etc. of fish (for example, salmon, red snapper, flounder, cod, sardine, tuna, etc.), or fish scale-derived hydrolyzed collagen obtained by hydrolyzing fish scales, but is not limited thereto.

[0016] The blending amount of the (B) component used in the skin cosmetic according to this embodiment is 0.0001% by mass or more and 3% by mass or less of the total mass of the skin cosmetic. From the viewpoint of usability, the blending amount of the (B) component is preferably 0.0005% by mass or more and 0.5% by mass or less, and more preferably 0.001% by mass or more and 0.2% by mass or less. If the blending amount of the (B) component is 0.0001% by mass or more, a sufficient skin moisturizing effect is obtained, and if it is 3% by mass or less, stickiness and odor can be suppressed. Note that, when two or more kinds of the (B) component are used in combination, the blending amount of the (B) component is the sum of them.

[0017] Hyaluronic acid and its salts, water-soluble collagen, and hydrolyzed collagen each have a moisturizing effect, but the moisturizing effect is synergistically improved by adding one or more of hyaluronic acid and its salts, water-soluble collagen, and hydrolyzed collagen to component (A).

[0018] <(C) Two or more types of polyethylene glycol with an average polymerization degree of 20 to 400> The component (C) used in the skin cosmetic according to this embodiment is two or more kinds of polyethylene glycols having an average degree of polymerization of 20 or more and 400 or less. Polyethylene glycol is a polymeric compound having a structure in which ethylene glycol is polymerized, and its feel, function, and display name in cosmetics and quasi-drugs vary depending on its average degree of polymerization. It is generally used for purposes such as moisturizing agents, thickeners, and binders, but by blending polyethylene glycols with different average degrees of polymerization, the effects can be more effectively obtained. The average degrees of polymerization of each of the two or more kinds of polyethylene glycols are preferably 20 to 40 for at least one kind and 75 to 400 for at least one kind. These components are available as commercially available cosmetic raw materials.

[0019] The blending amount of the (C) component used in the skin cosmetic according to this embodiment is 0.05% by mass or more and 12.0% by mass or less of the total mass of the skin cosmetic. From the viewpoint of usability, the blending amount of the (C) component is preferably 0.1% by mass or more and 5.0% by mass or less, more preferably 0.5% by mass or more and 2.0% by mass or less. If the blending amount of the (C) component is 0.05% by mass or more, the moisturizing effect can be improved by providing a moisturizing closed feeling. On the other hand, if the blending amount of the (C) component is 12.0% by mass or less, poor compatibility can be prevented. The blending amount of the (C) component is the total amount of two or more polyethyl glycols having an average degree of polymerization of 20 to 400.

[0020] In addition, component (B) has a specific unpleasant odor, and even when it is incorporated into a skin cosmetic, this unpleasant odor remains. However, the unpleasant odor can be suppressed by incorporating two or more types of polyethylene glycol with an average degree of polymerization of 20 to 400.

[0021] <(D) Diphenylsiloxyphenyl trimethicone> The component (D) used in the skin cosmetic according to this embodiment is diphenylsiloxyphenyl trimethicone. Diphenylsiloxyphenyl trimethicone is a type of phenyl-modified silicone. The blending amount of component (D) is 0.01% by mass or more and 8.0% by mass or less of the total mass of the skin cosmetic. From the viewpoint of usability, the blending amount of component (D) is preferably 0.05% by mass or more and 2.0% by mass or less, and more preferably 0.07% by mass or more and 0.5% by mass or less. If the blending amount of component (D) is 0.01% by mass or more, it is possible to impart smoothness to the skin, and if it is 8.0% by mass or less, it is possible to provide good stability and prevent poor compatibility.

[0022] <Other ingredients> In addition to the components described above, the skin cosmetic preparation according to this embodiment may contain other components, such as anionic surfactants, cationic surfactants, amphoteric surfactants, nonionic surfactants, oils, polymeric compounds, thickeners, powders (colorants, resins, pigments), preservatives, fragrances, moisturizers, physiologically active ingredients, mineral salts, solvents, antioxidants, chelating agents, pearlizing agents, neutralizing agents, pH adjusters, plant extracts, enzymes, and the like, as appropriate, provided such components do not impair the object of the present invention.

[0023] Furthermore, the skin cosmetic of the present invention may contain an appropriate amount of a physiologically active ingredient within the scope of the present invention.
