Description

[Technical field]

[0001] The present invention relates to an aqueous cosmetic preparation. [Background technology]

[0002] Aqueous cosmetic preparations such as lotions are widely used because they penetrate the skin and provide a moisturizing feeling. In recent years, the role of lotions is expected to go beyond simply increasing the moisture content of the skin, to impart elasticity to the skin after application (post-skin) to further enhance the moisturizing sensation. Conventionally, oils have been used as components for creating elasticity in cosmetics (Patent Document 1, etc.). Also, a large amount of thickening components such as polysaccharides and water-soluble polymers has been blended to create elasticity on the skin after application (Patent Document 2, etc.). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2014-076967 A [Patent Document 2] JP 2019-077675 A Summary of the Invention [Problem to be solved by the invention]

[0004] In aqueous cosmetics such as cosmetics, it is difficult to blend an effective amount of oil to impart a sufficient elasticity. Also, thickeners such as polysaccharides and water-soluble polymers can impart an elasticity, but they also give a sticky feeling to the skin surface, which is problematic in that the user cannot feel that the cosmetic is penetrating into the skin. In view of the above circumstances, an object of the present invention is to provide an aqueous cosmetic preparation that is excellent in the feeling of penetration and elasticity of the skin after application. [Means for solving the problem]

[0005] As a result of intensive research into solving the above problems, the inventors discovered that the above problems can be solved by combining a semi-solid nonionic surfactant with a specific polysaccharide, and thus completed the present invention.

[0006] That is, the present invention is as follows. [1] An aqueous cosmetic preparation comprising a nonionic surfactant that is semi-solid at 25°C and two or more polysaccharides, each of which has two or more monosaccharides as its constituent sugars. [2] The aqueous cosmetic preparation according to [1], wherein the nonionic surfactant is an alkyl ether having 12 to 40 carbon atoms to which polyoxyethylene and / or polyoxypropylene is added. [3] The aqueous cosmetic preparation according to [1] or [2], wherein the IOB value of the nonionic surfactant is 0.8 or more. [4] The aqueous cosmetic preparation according to any one of [1] to [3], wherein the polysaccharide is locust bean gum. [5] The aqueous cosmetic preparation according to [4], further comprising xanthan gum as the polysaccharide. [6] The aqueous cosmetic preparation according to any one of [1] to [5], wherein the total content of the polysaccharides is 0.01 to 0.5% by mass of the entire cosmetic preparation. [7] The aqueous cosmetic preparation according to any one of [1] to [6], wherein the content of the nonionic surfactant is 0.01 to 1 mass % of the entire cosmetic preparation. [8] The aqueous cosmetic preparation according to any one of [1] to [7], wherein the mass ratio of the content of the nonionic surfactant to the total content of the polysaccharides is 1:9 to 9:1. [9] The aqueous cosmetic preparation according to any one of [1] to [8], wherein the total content of the nonionic surfactant and the polysaccharide is 0.02 to 1.5 mass %. Effect of the Invention

[0007] The present invention provides an aqueous cosmetic composition that is excellent in the feeling of penetration and the elasticity of the skin after application. The aqueous cosmetic composition of the present invention is suitable for skin care cosmetics such as lotions because it provides a high moisturizing effect after application. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0008] The aqueous cosmetic preparation of the present invention essentially contains a nonionic surfactant that is semi-solid at 25°C and two or more polysaccharides.

[0009] The nonionic surfactant essentially contained in the aqueous cosmetic preparation of the present invention is semi-solid at 25° C. Here, the term "semi-solid" refers to a state in which, at 25° C. and atmospheric pressure, there is no fluidity and the surfactant hardly deforms in the absence of stress, but when a slight stress is applied, the surfactant deforms. Usually, the term "semi-solid" refers to a surfactant having a melting point of 30 to 55° C. under atmospheric pressure. Liquid surfactants tend to be sticky when applied, and solid surfactants tend to give a strong sense of firmness rather than elasticity, so that the desired feel on the skin after application cannot be obtained. Note that, as used herein, "liquid" refers to one that has fluidity at 25°C and atmospheric pressure, and "solid" refers to one that does not deform when stress is applied at 25°C and atmospheric pressure.

[0010] The nonionic surfactant is preferably an alkyl ether having polyoxyethylene (POE or PEG) and / or polyoxypropylene (POP or PPG) added thereto. The number of POE and POP added is not particularly limited, but is preferably 2 to 100, more preferably 2 to 60, and further preferably 6 to 50, independently. The number of carbon atoms of the alkyl ether is not particularly limited, but is preferably 12-40, more preferably 12-36, and further preferably 12-30.

[0011] The nonionic surfactant is preferably a so-called hydrophilic surfactant. Specifically, the IOB (Inorganic Organic Balance) value is preferably 0.8 or more, more preferably 0.9 or more, and even more preferably 1.0 or more. Here, the IOB value is the ratio of the organic value (OV) of a compound to the inorganic value (IB). The value (IV / OV) is calculated from the ratio of the inorganic value (IV) to the inorganic value (IV). (See, for example, pages 11-17 of "Organic Conceptual Diagram - Fundamentals and Applications" by Yoshio Koda, Sankyo Publishing, 1984.)

[0012] Examples of semi-solid nonionic surfactants preferred in the present invention include the following: Polyoxyethylene / polyoxypropylene alkyl ethers such as POE(15) oleyl ether, PPG-6 decyltetradeceth-20, PPG-6 decyltetradeceth-30, and PPG-8 ceteth-20; Polyoxyethylene / polyoxypropylene hydrogenated castor oils such as POE(30) hydrogenated castor oil, POE(40) hydrogenated castor oil; Polyoxyethylene / polyoxypropylene glycerin fatty acid esters, such as POE(15)glyceryl monooleate; Polyoxyethylene / polyoxypropylene sorbitan fatty acid esters such as POE(20) sorbitan monopalmitate, POE(20) sorbitan monostearate, POE(20) sorbitan monoisostearate, and POE(20) sorbitan monooleate ; Polyoxyethylene / polyoxypropylene sorbitol fatty acid esters, such as POE(6) sorbitol monolaurate, POE(60) sorbitol tetrastearate, and POE(60) sorbitol tetraoleate; Polyglycerol fatty acid esters such as hexaglyceryl monolaurate, hexaglyceryl monomyristate, pentaglyceryl monolaurate, pentaglyceryl monomyristate, pentaglyceryl monooleate, pentaglyceryl monostearate, decaglyceryl monolaurate, decaglyceryl monomyristate, decaglyceryl monostearate, decaglyceryl monoisostearate, decaglyceryl monooleate, and decaglyceryl monolinoleate. Of these, PPG-6 decyltetradeceth-20, PPG-6 decyltetradeceth-30, and PPG-8 ceteth-20 are particularly preferred.

[0013] The content of the semi-solid nonionic surfactant in the aqueous cosmetic preparation of the present invention is preferably 0.01 to 1 mass %, more preferably 0.01 to 0.5 mass %, and even more preferably 0.05 to 0.5 mass %, of the total cosmetic preparation. By using the composition in this range, the composition is easily absorbed into the skin upon application and also easily imparts an excellent elastic feel to the skin after application.

[0014] The polysaccharides essentially contained in the aqueous cosmetic preparation of the present invention each have two or more types of monosaccharides as constituent sugars. Examples of monosaccharides include glucose, fructose, xylose, mannose, galactose, lyxose, arabinose, glucuronic acid, glucosamine, acetylglucosamine, galacturonic acid, guluronic acid, mannuronic acid, etc., and the D- or L-forms of these are linked to form sugar chains. Examples of polysaccharides having two or more types of monosaccharides as constituent sugars include locust bean gum, guar gum, xanthan gum, hyaluronic acid, glucomannan, chitin, pectin, alginic acid, etc., and two or more of these are combined and contained in the aqueous cosmetic preparation of the present invention. The size of the polysaccharide may be such that it is generally used as a thickening agent to impart viscosity to cosmetics, for example, a molecular weight of about tens of thousands.

[0015] As the polysaccharide used in the present invention, it is preferable to use locust bean gum from the viewpoint of imparting a desired elasticity. In this case, it is preferable to further use xanthan gum. In addition, a commercially available raw material containing locust bean gum and xanthan gum in a mass ratio of 1:1 is "Nomcoat CG" (Nisshin Oillio Group, Ltd.), which can be preferably used.

[0016] The total content of polysaccharides in the aqueous cosmetic preparation of the present invention is preferably 0.01 to 0.5% by mass, more preferably 0.01 to 0.2% by mass, and even more preferably 0.01 to 0.1% by mass of the entire cosmetic preparation. By using the composition within this range, stickiness upon application is suppressed, the composition blends well with the skin, and the skin is easily provided with an excellent elastic feel after application.

[0017] The mass ratio of the content of the semi-solid nonionic surfactant to the total content of the polysaccharides in the aqueous cosmetic preparation of the present invention is preferably 1:9 to 9:1, more preferably 3:7 to 9:1, and even more preferably 5:5 to 9:1. Furthermore, the total content of the semi-solid nonionic surfactant and the polysaccharide in the aqueous cosmetic preparation of the present invention is preferably 0.02 to 1.5 mass %, more preferably 0.05 to 1.5 mass %, and even more preferably 0.05 to 1.0 mass %. By using the cosmetic composition within these ranges, it is easy to obtain a cosmetic composition that has a good balance between the feeling of penetration into the skin and the elasticity of the skin, and that has an excellent feeling when used.

[0018] The aqueous cosmetic preparation of the present invention can be produced by a conventional method. That is, the order of mixing is not particularly limited, and the components can be mixed in any order and by any method, and solubilized to obtain the composition.

[0019] The aqueous cosmetic preparation of the present invention generally contains water as the main medium. Specifically, the water content of the entire cosmetic preparation is preferably 50% by mass or more, more preferably 55% by mass or more, and even more preferably 60% by mass or more. The aqueous cosmetic preparation of the present invention is usually transparent since the blended components are solubilized in water, i.e., in a solubilized form. However, when hydrophobic powders or the like are contained, they may precipitate when left to stand, and the medium portion may be transparent. In this specification, transparency can be determined qualitatively by visual inspection, or quantitatively, it can be determined that the visible light transmittance (wavelength 600 nm, optical path length 1 cm) measured with a spectrophotometer at 25°C is in the range of 70 to 100, with the control distilled water being set at 100.

[0020] In addition, the aqueous cosmetic of the present invention preferably does not substantially contain oily components. Here, the term "oily components" refers to so-called oil agents, oil-soluble components, etc., and specifically refers to components that undergo phase separation from water after being suspended in water at 25 to 65°C and left to stand for 1 hour. Furthermore, "substantially free" means that the content of the cosmetic is preferably 3% by mass or less, more preferably 1% by mass or less, and even more preferably 0.1% by mass or less of the total cosmetic.

[0021] The aqueous cosmetic of the present invention contains a semi-solid nonionic surfactant, which is generally used for emulsification or solubilization of oily components, in order to improve the feel on the skin after application of the cosmetic. The surfactant has high affinity with the skin, and when combined with a specific polysaccharide, it is not sticky and has excellent penetration. In addition, even if it does not substantially contain an oil agent, it is possible to impart a good elastic feel to the skin after application. Therefore, the aqueous cosmetic composition of the present invention is suitable for use as a skin care cosmetic composition such as a lotion.
