Description

[Technical Field]

[0001] The present invention relates to a beauty kit and a beauty method using the same. [Background technology]

[0002] Factors that contribute to the worsening of skin conditions such as wrinkles, sagging skin, pigmentation, changes in skin tone, loss of skin elasticity, and disturbances in skin surface morphology include, for example, wrinkles and sagging caused by a decline in the function of dermal fibroblasts due to dryness and aging, the accompanying decrease and degeneration of dermal matrix such as collagen and elastin, and oxidative damage caused by external stress such as ultraviolet rays. Furthermore, while some aspects of pigmentation and changes in skin tone, including darkening of the skin, are unknown, they are thought to be caused by the production of melanin pigment due to hormonal abnormalities and stimulation by ultraviolet rays from sunlight, and among these, age spots and freckles are thought to be caused by abnormal deposition of melanin pigment.

[0003] Various methods have been investigated to solve these problems, including a topical skin preparation containing pullulan and tranexamic acid or a salt thereof (Patent Document 1), a whitening agent containing ethyl chlorogenic acid as an active ingredient (Patent Document 2), and a topical skin preparation containing tranexamic acid, a urethane resin, and gellan gum (Patent Document 3).

[0012] Hereinafter, an embodiment of the present invention will be described.

[0013] The foam cleanser of the present invention can be used for both cosmetics and quasi-drugs.

[0014] The higher fatty acids constituting the higher fatty acid salt used in the foam cleanser of the present invention may be either saturated or unsaturated, and may have a straight or branched chain. The number of carbon atoms constituting the higher fatty acid is preferably 8 to 24, and particularly preferably 10 to 24. These fatty acids may be used alone or in combination of two or more. Examples of straight-chain saturated fatty acids include lauric acid, myristic acid, palmitic acid, stearic acid, arachidic acid, behenic acid, lignoceric acid, oleic acid, coconut oil fatty acid, reduced coconut oil fatty acid, and palm kernel fatty acid. Examples of branched-chain fatty acids include isomyristic acid, isopalmitic acid, and isostearic acid. Among these fatty acids, it is preferable to use one or more selected from stearic acid, arachidic acid, behenic acid, and lignoceric acid in terms of massage effect, and it is most preferable to use behenic acid. Examples of alkaline agents that form salts with these higher fatty acids include alkali metal salts such as sodium and potassium, ammonium salts, alkanolamine salts such as monoethanolamine, diethanolamine, triethanolamine, 2-amino-2-methylpropanol, and 2-amino-2-methylpropanediol, and basic amino acid salts such as lysine and arginine. Of these, 2-amino-2-methylpropanol and arginine are particularly preferred.

[0015] Furthermore, these higher fatty acid salts do not necessarily need to be blended in the cleanser as fatty acid salts, and the above higher fatty acids and alkaline agents may be added separately to form fatty acid salts.

[0016] The amount of higher fatty acid and its salt is preferably 1 to 10% by mass, more preferably 1 to 8% by mass, of the total amount of the foam cleanser as higher fatty acid. If the amount is less than 1% by mass, sufficient cleansing power may not be exerted. If the amount is more than 10% by mass, the viscosity of the foam cleanser increases, and it may not be possible to discharge it.

[0017] The higher alcohol used in the foam cleanser of the present invention is a higher alcohol having 8 to 30 carbon atoms. Such higher alcohols are linear or branched, saturated or unsaturated hydrocarbon monohydric alcohols, and may be used alone or in combination of two or more. Specific examples include caprylyl alcohol, capryl alcohol, lauryl alcohol, myristyl alcohol, cetyl alcohol, hexyldecanol, stearyl alcohol, isostearyl alcohol, arachidyl alcohol, behenyl alcohol, lignoceryl alcohol, oleyl alcohol, carnaubyl alcohol, and ceryl alcohol. Among these higher alcohols, one or more selected from stearyl alcohol, arachidyl alcohol, behenyl alcohol, and lignoceryl alcohol are preferably used, with behenyl alcohol being most preferred from the viewpoint of massage properties.

[0018] The amount of higher alcohol is preferably 1 to 10% by mass, more preferably 1 to 8% by mass, based on the total amount of the foam cleanser. If the amount is less than 1% by mass, the foam cleanser may not exhibit sufficient massaging properties. If the amount is more than 10% by mass, the viscosity of the foam cleanser may increase, making it impossible to discharge.

[0019] The nonionic surfactant having an HLB value of 12 or more used in the foam cleanser of the present invention may be any surfactant used in ordinary cleansers, such as polyoxyethylene sorbitan fatty acid esters, polyglycerin fatty acid esters, polyoxyethylene fatty acid esters, polyoxyethylene alkyl ethers, and polyoxyethylene hydrogenated castor oil.

[0020] Examples of polyoxyethylene sorbitan fatty acid esters include POE (80) sorbitan monolaurate (HLB value 19.0), POE (20) sorbitan monolaurate (HLB value 16.9), POE (6) sorbitan monolaurate (HLB value 15.5), POE (20) sorbitan monopalmitate (HLB value 15.6), and POE (20) sorbitan monostearate (HLB value 14.9). Examples of polyglycerin fatty acid esters include hexaglyceryl monolaurate (HLB value 14.5) and decaglyceryl monolaurate (HLB value 15.5). Examples of polyoxyethylene fatty acid esters include POE (10) monolaurate (HLB value 12.5), POE (25) monostearate (HLB value 15.0), and POE (240) monostearate (HLB value 17.5). Examples of polyoxyethylene alkyl ethers include POE (9) lauryl ether (HLB value 14.5), POE (10) cetyl ether (HLB value 13.5), POE (20) phytosterol ether (HLB value 15.5), POE (30) phytosterol ether (HLB value 18.0), POE (25) phytostanol (HLB value 14.5), etc. Examples of polyoxyethylene hydrogenated castor oils include POE (40) hydrogenated castor oil (HLB value 12.5), POE (60) hydrogenated castor oil (HLB value 14.0), etc.

[0021] Here, the HLB value (Hydphile-Lipophile Balance) in the present invention is an index showing the balance of hydrophilicity and lipophilicity, and is calculated by Oda and Teramura et al. using the following formula (1): HLB value = inorganic value (IV) / organic value (OV) × 10 (Equation 1) (See Yoshio Koda, "Organic Conceptual Diagram - Fundamentals and Applications", pp. 11-17, Sankyo Publishing, 1984)

[0022] The amount of nonionic surfactants with an HLB value of 12 or more is preferably 1 to 10% by mass, more preferably 1 to 8% by mass, based on the total amount of the foam cleanser. If the amount is less than 1% by mass, rinsing performance may be poor. If the amount is more than 10% by mass, the rinsing effect may not be improved, which is inefficient.

[0023] The propellant used in the foam cleanser of the present invention contains carbon dioxide as an essential component.

[0024] From the viewpoint of cosmetic effects, it is preferable that the amount of carbon dioxide is 1 to 100% by mass of the total amount of the propellant.

[0026] The amount of propellant filled in the foam cleanser of the present invention is preferably 0.5% by mass or more, more preferably 1% by mass or more, and preferably 10% by mass or less, more preferably 8% by mass or less, when the total amount of the foam cleanser concentrate and propellant is taken as 100% by mass, from the viewpoints of improving the foam quality immediately after ejection, improving the re-foaming ability of the foam cleanser, and obtaining an appropriate spray speed.

[0027] The foam cleanser of the present invention is filled into an aerosol container for use. Examples of such aerosol containers include known pressure-resistant containers made of metal or the like, and double-structure containers in which an inner bag is housed inside a pressure-resistant container. In the case of double-structure containers, it is preferred that the foam cleanser be filled into the inner bag, and a propellant be filled between the pressure-resistant container and the inner bag.

[0028] The method for preparing the foam cleanser of the present invention is not particularly limited. For example, it can be prepared by filling a pressure-resistant container that constitutes an aerosol container with the foam cleanser, attaching a valve, and then filling the propellant through the valve.

[0029] The foam cleanser of the present invention may contain bases other than the above-mentioned essential ingredients as long as the effects of the present invention are not impaired. Specific examples of such bases include oils, surfactants other than those mentioned above, thickeners, preservatives, fragrances, moisturizers, antioxidants, anti-inflammatory agents, and antibacterial agents.
