Description

Ceramide complex-containing composition and cosmetic 【0001】 The present invention relates to a ceramide complex-containing composition and a cosmetic. 【0002】 Ceramide is present in the stratum corneum of the skin and hair, constructs a lipid barrier necessary for moisture retention, and plays an important role in maintaining moisture. Six different types of ceramides exist in human skin and hair, and their functions are also different. In anticipation of the expression of the functions of ceramide, various products containing ceramide have been developed. 【0003】 Patent Document 1 describes a ceramide dispersion composition containing ceramide, a polyhydric alcohol, a nonionic surfactant, and an amphoteric surfactant. 【0004】 Japanese Patent Application Laid-Open No. 2015-30705 【0005】 However, the ceramide dispersion composition described in Patent Document 1 still had room for improvement in terms of hair strength, hair softness, hair and skin moisture content, etc. The present invention aims to provide a composition containing ceramide that can improve hair strength, hair softness, and hair and skin moisture content. The present invention also aims to provide a cosmetic containing the above composition containing ceramide. 【0006】 The present invention relates to the following ceramide complex-containing composition. A ceramide complex-containing composition comprising a ceramide complex comprising ceramide, a dihydric alcohol, and an amphoteric surfactant. The present invention further relates to a cosmetic containing the above ceramide complex-containing composition. 【0007】 According to the ceramide complex-containing composition and the cosmetic of the present invention, hair strength, hair softness, and hair and skin moisture content can be improved. 【0008】<Ceramide Complex-Containing Composition> The ceramide complex-containing composition according to the embodiment of the present invention (hereinafter also referred to as "this composition") contains ceramide, a dihydric alcohol, and an amphoteric surfactant. Because the ceramide is in a complex state, hair strength, hair flexibility, and hair and skin moisture content can be improved compared to when ceramide is contained alone. This is thought to be because the ceramide being in a complex state with the amphoteric surfactant enhances the adsorption of ceramide to the hair surface and skin surface, and the penetration of the amphoteric surfactant into the hair and skin interior. It is presumed that the ceramide forms an ionic complex in the composition. The amphoteric surfactant has both positive and negative ion properties, and ceramide has positive ion properties. In this composition, it is thought that the positive ions of ceramide and the negative ions of the amphoteric surfactant interact ionically to form a complex. In this complex, the positive ions of the amphoteric surfactant do not participate in the interaction with ceramide, so the ceramide complex as a whole has positive ion properties. Here, since the surface of hair and skin is generally negatively charged, the positively charged ceramide complex is more likely to adsorb to the surface of hair and skin through ionic interactions. As a result, the combined amphoteric surfactant penetrates into the interior of the hair and skin, and the ceramide ionically combined with the amphoteric surfactant is thought to remain more strongly on the surface of the hair and skin. Therefore, it is thought that improvements in hair strength, hair flexibility, and hair and skin moisture content can be obtained compared to when ceramide is contained alone. 【0009】One reason why the ceramide dispersion composition described in Patent Document 1 does not produce the effects such as hair strength as in the present invention is that, according to the method of producing the composition described in Patent Document 1, the ceramide does not form a complex in the composition. As will be described later, in order for ceramide to form a complex in the composition according to the present invention, it is preferable not to add water when dispersing ceramide in a dihydric alcohol. Patent Document 1 describes that a ceramide dispersion composition can be obtained by mixing an aqueous phase component containing a polyhydric alcohol with an oil phase component containing ceramide. Furthermore, another reason why the ceramide dispersion composition described in Patent Document 1 does not produce the effects as in the present invention is thought to be that the polyhydric alcohol substantially used in Patent Document 1 is glycerin, i.e., a trihydric alcohol. In contrast, the present composition uses a dihydric alcohol, which provides effects such as the penetration of the amphoteric surfactant into the inside of the hair and skin compared to a trihydric alcohol. This is presumed to be because using a dihydric alcohol results in higher dispersibility of ceramide and amphoteric surfactant than using a trihydric alcohol, allowing for the formation of an optimal complex. 【0010】 In this composition, ceramides with a naturally derived structure are preferred. Ceramides with a naturally derived structure may be extracted from nature, or obtained by fermentation and / or synthesis. Examples of ceramides with a naturally derived structure include ceramide 1, ceramide 2, ceramide 3, ceramide 4, ceramide 5, ceramide 6B, and ceramide 7, which differ in the structure of sphingosine and long-chain fatty acids. Two or more of these may be used in mixture form. Of these, ceramide 1, ceramide 2, ceramide 3, ceramide 5, and ceramide 6B are preferred from the viewpoint of availability, and ceramide 2 and ceramide 3, which are known to be the main components of ceramide in hair, are more preferred, with ceramide 2 being the most preferred. Commercially available ceramides may also be used. 【0011】Examples of dihydric alcohols in this composition include propylene glycol, 1,3-propanediol, dipropylene glycol, 1,3-butylene glycol, 2,3-butylene glycol, 1,2-pentanediol, 1,5-pentanediol, isoprene glycol, hexylene glycol, 1,2-hexanediol, and 1,6-hexanediol. Two or more of these may be used in mixture form. Of these, dipropylene glycol is particularly preferred from the viewpoint of usability and dispersibility. 【0012】 Examples of amphoteric surfactants in this composition include glycine-type amphoteric surfactants, betaine-type amphoteric surfactants, amine oxide-type amphoteric surfactants, and lecithins. Examples of glycine-type amphoteric surfactants include sodium cocoamphoacetate, sodium lauroamphoacetate, and sodium cocanphodiacetate. Examples of betaine-type amphoteric surfactants include aminoacetic acid betaine-type surfactants and sulfobetaine-type surfactants. Examples of aminoacetic acid betaine-type surfactants include cocamidopropyl betaine, lauramidopropyl betaine, myristamidopropyl betaine, palm kernel fatty acid amidopropyl betaine, lauryl betaine, and cocobetaine. Examples of sulfobetaine-type surfactants include lauryl hydroxysultaine, lauramidopropyl hydroxysultaine, and cocamidopropyl hydroxysultaine. Examples of amine oxide-type amphoteric surfactants include lauramine oxide and lauramidopropylamine oxide. Examples of lecithins include lecithin, lysolecithin, hydrogenated lecithin, and hydrogenated lysolecithin. Two or more amphoteric surfactants may be used in combination. Of these, betaine-type surfactants are preferred from the viewpoint of usability and irritation, aminoacetic acid betaine-type surfactants and sulfobetaine-type surfactants are more preferred, and cocamidopropyl betaine is particularly preferred. 【0013】In this composition, the ratio of ceramide to amphoteric surfactant is preferably 6:1 to 1:6 in molar ratio, more preferably 5:1 to 1:5, particularly preferably 3:1 to 1:3, and most preferably 1:1. This molar ratio of ceramide to amphoteric surfactant is preferable because it results in less residue that does not form complexes, and adsorption and penetration are effective. 【0014】 In this composition, the proportion of dihydric alcohol is preferably 80% to 99% by mass, more preferably 85% to 95% by mass, and particularly preferably 88% to 92% by mass. Having the proportion of dihydric alcohol within this range is effective and preferable in terms of dispersibility and stability. 【0015】 In this composition, the ceramide, dihydric alcohol, and amphoteric surfactant are thought to form a complex as described above. More specifically, it is thought that the ceramide and amphoteric surfactant mainly form a complex and are dispersed in the viscous liquid dihydric alcohol through ionic interactions. Furthermore, since particles with a particle size of 10 to 100 μm have been confirmed by polarized light observation and light scattering measurements of this composition under a microscope, the size of the complex is estimated to be about 10 to 100 μm. It is presumed that the inclusion of such a complex in this composition makes the ceramide more easily dispersed, making it easier to disperse when incorporated into cosmetics, and improving its adsorption to the surface of hair and skin. 【0016】 The ceramide complex in this composition may contain other components besides the ceramide, dihydric alcohol, and amphoteric surfactant mentioned above. Examples of other components include cationic surfactants, anionic surfactants, nonionic surfactants, cationic polymers, anionic polymers, and nonionic polymers. The proportion of other components is preferably 0.01 to 5% by mass. 【0017】 This composition may contain components other than the ceramide complex, as long as it does not deviate from the effects of the present invention. Examples include residual ceramide not involved in the ceramide complex, amphoteric surfactants, and dihydric alcohols. It may also contain preservatives, antioxidants, bactericides, chelating agents, etc. 【0018】 From the viewpoint of facilitating the formation of ceramide complexes, this composition preferably has a moisture content of 10% by mass or less, and more preferably 5% by mass or less. 【0019】 This composition can be obtained by dispersing ceramide and an amphoteric surfactant in a dihydric alcohol. The ceramide and amphoteric surfactant may be dispersed simultaneously, or one may be dispersed first and the other later. When dispersing ceramide in a dihydric alcohol, it is preferable to use the ceramide in a solid state and to disperse it without adding water. This facilitates the formation of a ceramide complex. If water is present during ceramide dispersion, the formation of a ceramide complex is difficult. The amphoteric surfactant may be in a solid state or an aqueous solution state, but if used in an aqueous solution state, it is preferable to mix it after dispersing the ceramide in the dihydric alcohol, and it is even preferable to remove the water after mixing. 【0020】 When dispersing ceramide, it is preferable to heat it to 85°C to 100°C, and more preferably to 90°C to 95°C, from the viewpoint of improving dispersibility. 【0021】 <Cosmetics> This ceramide complex-containing composition is effective in improving the penetration of ceramide into the hair and skin, hair strength, hair flexibility, and hair and skin moisture content, and can therefore be incorporated into various cosmetics. The content of this ceramide complex-containing composition in the cosmetics of this embodiment can be selected according to the type of cosmetic, preferably 0.00001 to 10% by mass, more preferably 0.0001 to 1% by mass, and most preferably 0.001 to 0.1% by mass. 【0022】Cosmetics may contain, as needed, additives commonly found in cosmetics, such as oily bases, moisturizers, texture enhancers, surfactants, polymers, thickeners / gelling agents, solvents, propellants, antioxidants, reducing agents, oxidizing agents, antibacterial agents, preservatives, chelating agents, pH adjusters, acids, alkalis, powders, inorganic salts, UV absorbers, whitening agents, vitamins and their derivatives, anti-inflammatory agents, hair growth agents, blood circulation promoters, stimulants, hormones, anti-wrinkle agents, anti-aging agents, tightening agents, cooling agents, warming agents, wound healing promoters, irritation relievers, analgesics, cell activators, plant / animal / microbial extracts, antipruritics, exfoliating / dissolving agents, antiperspirants, cooling agents, astringents, enzymes, nucleic acids, fragrances, pigments, colorants, dyes, pigments, water, etc. 【0023】As oily bases, higher alcohols such as cetanol, myristyl alcohol, oleyl alcohol, lauryl alcohol, cetostearyl alcohol, stearyl alcohol, arachidodecanol, behenyl alcohol, jojoba alcohol, chymyl alcohol, cerachidodecanol, batyl alcohol, hexyldecanol, isostearyl alcohol, 2-octyldodecanol, dimergol, etc.; aralkyl alcohols and derivatives such as benzyl alcohol; lauric acid, myristic acid, palmitic acid, stearic acid, isostearic acid, behenyl alcohol.
