Abstract
Description
【Technical Field】 【0001】 The present invention relates to an external preparation for skin. 【Background Art】 【0002】 Among various skin problems, "deep wrinkles" that occur on the skin with aging are one of the major concerns for women. Wrinkles include "shallow wrinkles" caused by dryness or mild external environmental changes, and "deep wrinkles" caused by factors such as photoaging or natural aging, which result in the alteration of dermal components. The former is relatively easy to improve by skin care such as moisturizing, while the latter is known to be difficult to improve without appropriate beauty ingredients or skin care. 【0003】 Regarding skin problems related to such deep wrinkles, in particular, niacinamide is known to be a vitamin with high safety and having an anti-skin aging effect (for example, Patent Document 1). However, when niacinamide is formulated at a high concentration, it is known to have an undesirable feeling of roughness, and improvements have been made in this regard. Examples include water-in-oil emulsified cosmetics using silicone oil and polyoxyalkylene-added glycerin derivatives (for example, Patent Document 2), gel-like external preparations for skin using silicone oil, polyether-modified silicone, and carboxymethyl cellulose (for example, Patent Document 3), leave-on skin care compositions using petrolatum (for example, Patent Document 4), etc. 【Prior Art Documents】 【Patent Documents】 【0004】 【Patent Document 1】 Japanese Patent No. 3922311 【Patent Document 2】 International Publication No. 2021 / 201136 【Patent Document 3】 Japanese Patent No. 7256624 【Patent Document 4】 Japanese Patent Application Publication No. 2003-502435 【Summary of the Invention】 [Problems that the invention aims to solve] 【0005】 The conventional topical skin preparations described above improve the squeaky feeling caused by niacinamide using oil-based methods, but methods to improve this squeaky feeling without relying on oil have not been sufficiently investigated. Given this background, there is a need for topical skin preparations containing niacinamide that suppress the squeaky feeling. 【0006】 This invention has been made in view of the above circumstances, and its purpose is to provide a topical skin preparation containing niacinamide that suppresses the feeling of tightness. [Means for solving the problem] 【0007】 As a result of diligent research to achieve the above objectives, the inventors of the present invention have discovered that by combining niacinamide, diglycerin, amino acids and their salts, it is possible to provide a topical skin preparation that does not feel sticky or greasy, has excellent moisturizing properties for the skin, and provides firmness and elasticity, thus completing the present invention. 【0008】 The topical skin preparation according to the present invention is a topical skin preparation containing the following (A) to (C). (A) Niacinamide 0.1-6% by mass (B) Diglycerin 0.1-4% by mass (C) One or more amino acids and their salts selected from 0.0001 to 0.5% by mass 【0009】 The topical skin preparation according to the present invention may contain the following (D). (D) One or more extracts or fermented products selected from yuzu, soybeans, lotus, royal jelly, and scutellaria baicalensis, in a quantity of 0.0001-0.5% by mass. [Effects of the Invention] 【0010】 This invention makes it possible to suppress the squeaky feeling caused by niacinamide. [Modes for carrying out the invention] 【0011】 The following describes in detail the topical skin preparation according to this embodiment, but the present invention is not limited to the following embodiments. The present invention is not limited to the configurations described below, and various modifications are possible within the scope of the claims, and embodiments and examples obtained by appropriately combining the technical means disclosed in different embodiments and examples are also included in the technical scope of the present invention. Furthermore, unless otherwise specified in this specification, "A~B" representing a numerical range means "A or more, B or less". 【0012】 The topical skin preparation according to this embodiment contains (A) niacinamide, (B) diglycerin, and (C) one or more selected from amino acids and their salts. 【0013】 <(A) Niacinamide> Component (A) used in the topical skin preparation according to this embodiment is niacinamide. Niacinamide is one of the B vitamins, which are water-soluble vitamins, and is also called nicotinamide. Niacinamide can be used without particular restrictions as long as it is commonly used in pharmaceuticals, quasi-drugs, and cosmetics, and these may be natural or synthetic. Niacinamide is known to have effects such as wrinkle improvement, blood circulation promotion, rough skin improvement, melanin production inhibition, and skin whitening. 【0014】 Niacinamide is available as a commercially available cosmetic ingredient. Examples of commercially available products include "Niacinamide USP PC (manufactured by Arcsada Japan)" and "Nicotinamide (manufactured by DSM)." 【0015】 The topical skin preparation according to this embodiment can suppress a prickling sensation by containing niacinamide as component (A) and one or more selected from (C) amino acids and their salts described below. 【0016】 The blending amount of component (A) is 0.1 to 6% by mass in the total mass of the topical skin preparation, preferably 0.5 to 5% by mass. If the blending amount of component (A) is 0.1% by mass or more, a sufficient moisturizing effect and an effect of improving the firmness of the skin can be obtained. On the other hand, if the blending amount of component (A) is 6% by mass or less, prickling can be suppressed by combining with component (C) described below. 【0017】 <(B) Diglycerin> Component (B) used in the topical skin preparation according to this embodiment is diglycerin. Diglycerin is a kind of polyhydric alcohol having four hydroxyl groups, which is a dimer in which two glycerins are bonded. 【0018】 Component (B) in the topical skin preparation according to this embodiment gives moisture (moisturizing effect) to the skin. 【0019】 The blending amount of component (B) is 0.1 to 4% by mass in the total mass of the topical skin preparation, preferably 0.3 to 3% by mass. If the blending amount of component (B) is 0.1% by mass or more, a sufficient moisturizing effect can be obtained.

Amino acids are a general term for organic compounds having carboxyl and amino functional groups, and are classified into α-amino acids, β-amino acids, γ-amino acids, δ-amino acids, etc., depending on the position of the functional groups, but are not particularly limited as long as they are used as components of topical skin preparations in the fields of pharmaceuticals, quasi-drugs, or cosmetics. These components are available as commercially available cosmetic raw materials. The amino acids used in the topical skin preparation of the present invention are not particularly limited, but include glycine, serine, threonine, alanine, valine, leucine, isoleucine, asparagine, glutamine, cysteine, methionine, phenylalanine, tyrosine, tryptophan, citrulline, azaserine, cystathionine, homocysteine, S-adenosylhomocysteine, S-adenosylmethionine, ε-N-acetyllysine, proline, 4-hydroxyproline, N-methylglycine, N-acetylserine, N-acetylcysteine, arginine, lysine, histidine, ornithine, ω-N-methylarginine, ε-N,N,N-trimethyllysine, 5-hydroxylysine, 3-methylhistidine, aspartic acid, glutamic acid, γ-carboxyglutamic acid, O-phosphoserine, aminobutyric acid, etc. In addition, salts of the above-mentioned amino acids may be used as component (C) of the topical skin preparation according to this embodiment. Examples of amino acid salts include sodium salts, potassium salts, magnesium salts, and calcium salts. 【0021】 In the topical skin preparation according to this embodiment, component (C), when included together with component (A), suppresses tightness and further synergistically improves firmness and elasticity. 【0022】 The amount of component (C) is 0.0001 to 0.5% by mass of the total mass of the topical skin preparation, preferably 0.001 to 0.1% by mass. If the amount of component (C) is 0.0001% by mass or more, it can suppress the squeaking caused by component (A) and the stickiness caused by component (B). On the other hand, if the amount of component (C) is 0.5% by mass or less, it can suppress the unpleasant odor caused by component (C). If the topical skin preparation contains multiple types of amino acids and their salts, which are component (C), the amount of component (C) is the total amount of the amino acids and their salts. 【0023】 The topical skin preparation according to this embodiment contains (A) 0.1 to 6% by mass of niacinamide, (B) 0.1 to 4% by mass of diglycerin, and (C) 0.0001 to 0.5% by mass of one or more amino acids and their salts, thereby suppressing the squeaky feeling caused by niacinamide, further suppressing skin stickiness, and providing moisture and firmness to the skin. 【0024】 <(D) Extracts and fermented products of yuzu, soybeans, lotus, royal jelly, and scutellaria baicalensis> The topical skin preparation according to this embodiment may optionally contain, as an additional (D) component, an extract or fermented product of yuzu, soybean, lotus, royal jelly, or scutellaria baicalensis. The topical skin preparation may contain only one of the extracts and fermented products of yuzu, soybean, lotus, royal jelly, or scutellaria baicalensis as component (D), or two or more. 【0025】 The topical skin preparation according to this embodiment synergistically improves firmness and elasticity by containing component (D). 【0026】 If the topical skin preparation according to this embodiment contains component (D), the amount of component (D) is preferably 0.0001 to 0.5% by mass of the total mass of the topical skin preparation, and more preferably 0% by mass. The amount is 0.001 to 0.1% by mass. If the amount of component (D) is 0.0001% by mass or more, firmness and elasticity can be further improved. On the other hand, if the amount of component (D) is 0.5% by mass or less, unpleasant odors derived from component (D) can be suppressed. In addition, if the topical skin preparation contains multiple types of extracts and fermented products of component (D), such as yuzu, soybean, lotus, royal jelly, and scutellaria baicalensis, the amount of these components is the total amount of amino acids and their salts. 【0027】 <Other ingredients> In addition to the components described above, the topical skin preparation according to this embodiment may appropriately contain other components, such as anionic surfactants, cationic surfactants, amphoteric surfactants, nonionic surfactants, oils, polymer compounds, thickeners, powders (dyes, resins, pigments), preservatives, fragrances, moisturizers, physiologically active ingredients, mineral salts, solvents, antioxidants, chelating agents, pearlescent agents, neutralizing agents, pH adjusters, and other components such as plant extracts and enzymes not listed in component (D) used in the topical skin preparation of the present invention, as long as the objective of the present invention is not impaired. 【0028】 Furthermore, the topical skin preparation according to this embodiment may contain physiologically active ingredients as appropriate, as long as it does not impair the objectives of the present invention.
