Description

[Technical Field]

[0001] The present invention relates to a body cleansing composition that can be suitably used on the skin, hair, and scalp. [Background technology]

[0002] With consumers' increasing aesthetic awareness and diversifying lifestyles, the number of personal care products on the market has increased, and daily care has become more complex. On the other hand, there is a growing demand for simple and efficient products that require less effort and save time. Body cleansing compositions can cleanse not only the skin but also the hair, thus reducing effort and meeting the demand for time-saving products. They are one such product that fulfills multiple roles in one.

[0003] Body cleansing compositions must possess basic cleansing properties such as foaming ability, and due to their characteristics, they must provide a pleasant user experience when used on both skin and hair. In particular, the feel during rinsing is an important element of the user experience of a body cleanser, and it is preferable that it does not leave a slimy feeling on the skin and does not leave a squeaky feeling on the hair.

[0004] For example, Patent Document 1 describes a cleansing composition for the body and hair that does not leave a sticky residue when used, containing a specific ratio of a fatty acid alkylene oxide derivative, a polyoxyalkylene polyol isostearate ester, a taurine derivative, and an alkyl betaine or alkylamide betaine type amphoteric surfactant.

[0005] Furthermore, Patent Document 2 describes a body cleansing composition containing an anionic surfactant, an imidazoline-based amphoteric surfactant, and an amphoteric surfactant excluding the imidazoline-based surfactant, which has excellent foaming properties and can suppress a squeaky feeling when used on hair.

[0006] Furthermore, Patent Document 3 describes a body cleansing composition that contains an amphoteric surfactant and a cationic polymer with a specific cationic charge density, and is dispensed from a foaming container, which does not leave a sticky feeling when used on the skin and suppresses a squeaky feeling when used on the hair.

[0008] In recent years, scalp massage has gained increasing attention as a form of scalp care that can be done at home. While scalp massage is generally performed after bathing, it can be considered a time-consuming process. Therefore, there is a demand for body cleansing compositions that also offer excellent scalp massage properties. Furthermore, considering bathing time, a composition that provides a high massage effect in a short amount of time is preferable. However, until now, there has been no body cleansing composition that satisfies the user experience of a body cleanser while also offering excellent scalp massage properties in a short amount of time.

[0009] The object of the present invention is to provide a body cleansing composition that has excellent foaming properties, does not leave a sticky feeling when used on the skin, suppresses a squeaky feeling when used on the hair, and provides a high massage effect to the scalp in a short amount of time.

Advantages of the Invention

[0014] The body cleansing composition of the present invention has excellent foaming properties, is not sticky when used on the skin, can suppress the squeaking feeling when used on the hair, and further has a feel that allows a high massage effect to be felt on the scalp in a short time.

Embodiments for Carrying Out the Invention

[0015] Each component of the cleansing composition of the present invention will be sequentially described. 〔Component (A)〕 Component (A) used in the present invention is an acylalkyltaurine type surfactant represented by the above formula (1).

[0016] In formula (1), R 1 is an alkyl group having 7 to 21 carbon atoms or an alkenyl group having 7 to 21 carbon atoms. In other words, R 1 CO is an acyl group having 8 to 22 carbon atoms, that is, a residue obtained by removing a hydroxyl group (-OH) from a fatty acid (R 1 COOH). Such a fatty acid (R 1 COOH) may be a straight-chain fatty acid or a branched-chain fatty acid. Examples of such fatty acids include saturated fatty acids such as caprylic acid, capric acid, lauric acid, myristic acid, palmitic acid, stearic acid, and isostearic acid; unsaturated fatty acids such as palmitoleic acid, oleic acid, elaidic acid, linoleic acid, and linolenic acid; and coconut oil fatty acid, palm kernel oil fatty acid, beef tallow fatty acid, and hydrogenated beef tallow fatty acid, which are mixtures thereof. Among these, lauric acid, myristic acid, coconut oil fatty acid, and palm kernel oil fatty acid are preferred.

[0017] Also, when the number of carbon atoms of R 1 is less than 7, the foaming property may be insufficient, so it is set to 7 or more, preferably 9 or more, and more preferably 11 or more. Also, R1 When the carbon number exceeds 21, there may be a lack of smoothness when used on hair and an insufficient massage effect on the scalp in a short time. Therefore, the carbon number is set to 21 or less, preferably 17 or less, and more preferably 15 or less. Further, R 1 may be a linear alkyl group or a linear alkenyl group, or may be a branched alkyl group or a branched alkenyl group.

[0021] Furthermore, one or more of the above-mentioned acylalkyltaurine-type surfactants can be used as components.

[0022] In the present invention, the content of component (A) is 1 to 20% by mass of the total amount of the body cleansing composition. If the content of component (A) is less than 1% by mass, there is a risk that the foaming ability and the lack of slipperiness when used on the skin will be insufficient, so it should be 1% by mass or more, preferably 3% by mass or more, and more preferably 5% by mass or more. Furthermore, if the content of component (A) exceeds 20% by mass, there is a risk that the lack of squeaky feeling when used on the hair and the massage effect on the scalp in a short time will be insufficient, so it should be 20% by mass or less, preferably 15% by mass or less, and more preferably 12% by mass or less.

[0023] [Component (B)] Component (B) used in the present invention is an amphoteric surfactant. Component (B) is a surfactant having a structure that combines a cationic group and an anionic group. Preferably, component (B) has an N-acyl group or an N-alkyl group.

[0024] Furthermore, when an amphoteric surfactant contains an N-acyl group, the acyl group directly bonded to the nitrogen atom is, for example, a residue obtained by removing a hydroxyl group from a straight-chain fatty acid having 8 to 18 carbon atoms or a branched-chain fatty acid having 8 to 18 carbon atoms. Examples of such fatty acids include saturated fatty acids such as caprylic acid, capric acid, lauric acid, myristic acid, palmitic acid, stearic acid, and isostearic acid; unsaturated fatty acids such as palmitoleic acid, oleic acid, elaidic acid, linoleic acid, and linolenic acid; and mixtures thereof such as coconut oil fatty acids, palm kernel oil fatty acids, beef tallow fatty acids, and hydrogenated beef tallow fatty acids. Of these, lauric acid, myristic acid, palmitic acid, oleic acid, coconut oil fatty acids, and palm kernel oil fatty acids are preferred. Particularly preferred are lauric acid, coconut oil fatty acids, and palm kernel oil fatty acids.

[0025] When the above amphoteric surfactant contains an N-alkyl group, the alkyl group directly bonded to the nitrogen atom is, for example, an alkyl group having 8 to 18 carbon atoms, and also includes mixed alkyl groups derived from mixed fatty acids. Examples include alkyl groups such as caprylyl, caprylyl, lauryl, myristyl, palmityl, stearyl, and oleyl groups; and mixed alkyl groups such as coconut oil alkyl groups, palm kernel oil alkyl groups, and beef tallow alkyl groups. Of these, lauryl, myristyl, palmityl, coconut oil alkyl groups, and palm kernel oil alkyl groups are preferred. Particularly preferred are lauryl, coconut oil alkyl groups, and palm kernel oil alkyl groups.

[0026] Examples of amphoteric surfactants for component (B) include alkyl betaine, alkylamide betaine, alkyl hydroxysulfobetaine, alkylamide hydroxysulfobetaine, alkylcarboxymethylhydroxyethylimidazolinium betaine, alkylamide hydroxyethyl amino acid type amphoteric surfactant, and alkyliminodiacetate.

[0027] Component (B) can be one or more selected from amphoteric surfactants.

[0028] In the present invention, the content of component (B) is 1 to 15% by mass of the total amount of the body cleansing composition. If the content of component (B) is less than 1% by mass, there is a risk that the lack of squeaky feeling when used on the hair and the massage effect on the scalp in a short time will be insufficient, so it should be 1% by mass or more, preferably 3% by mass or more, and more preferably 5% by mass or more. Also, if the content of component (B) exceeds 15% by mass, there is a risk that the lack of slipperiness when used on the skin will be insufficient, so it should be 15% by mass or less, preferably 12% by mass or less, and more preferably 10% by mass or less.

[0029] [Component (C)] The component (C) used in the present invention is an aminoethylsulfonate in which a hydrogen atom or an alkyl group having 1 to 3 carbon atoms is bonded to the nitrogen atom of the amino group, and the counterion is an alkali metal ion, a 1 / 2 alkaline earth metal ion, or an organic ammonium.

[0030] The alkyl group having 1 to 3 carbon atoms may be a linear alkyl group or a branched alkyl group. Examples of this alkyl group include a methyl group, an ethyl group, an n-propyl group, and an isopropyl group. Of the hydrogen atoms or C1 to 3 alkyl groups that the amino group may have, a hydrogen atom and a methyl group are preferred, and a methyl group is more preferred.

[0031] Examples of counterions that form component (C) include, but are not limited to, sodium ions, potassium ions, magnesium ions, calcium ions, monoethanolammonium, diethanolammonium, and triethanolammonium. Among these, sodium ions, potassium ions, magnesium ions, calcium ions, and triethanolammonium are preferred, and sodium ions are even more preferred.

[0032] Specific examples of component (C) include, for example, sodium β-taurine and sodium N-methyl-β-taurine.

[0033] As component (C), one of the above-mentioned aminoethylsulfonates can be used alone, or two or more can be used in combination.

[0034] In the present invention, the content of component (C) is 0.001 to 0.5% by mass of the total amount of the body cleansing composition. If the content of component (C) is less than 0.001% by mass, there is a risk that foaming ability, lack of squeaky feeling when used on hair, and massage effect on the scalp in a short time will be insufficient. Therefore, it should be 0.001% by mass or more, preferably 0.005% by mass or more, and more preferably 0.01% by mass or more. Furthermore, if the content of component (C) exceeds 0.5% by mass, there is a risk that foaming ability and lack of slipperiness when used on skin will be insufficient. Therefore, it should be 0.5% by mass or less, preferably 0.3% by mass or less, and particularly preferably 0.15% by mass or less.

[0035] [Mass ratio of component (A) to component (C)] In this invention, the mass ratio ((A) / (C)) of the mass of component (A) to the mass of component (C) is set to 10 to 3000. If the mass ratio ((A) / (C)) exceeds 3000, there is a risk that the lack of squeaky feeling when used on hair and the massage effect on the scalp in a short time will be insufficient, so it should be 3000 or less, preferably 2000 or less, more preferably 500 or less, particularly preferably 400 or less, and most preferably 300 or less. Also, if the mass ratio ((A) / (C)) is less than 10, there is a risk that the foaming ability and the lack of slipperiness when used on skin will be insufficient, so it should be 10 or more, preferably 40 or more, more preferably 100 or more, and particularly preferably 180 or more.

[0036] [Component (D)] In addition to the above-mentioned components (A) to (C), the body cleansing composition of the present invention may also contain component (D).

[0037] The component (D) used in the present invention is phenoxyethanol and / or ethylhexylglycerin. Phenoxyethanol is a monoether of ethylene glycol and phenol. Ethylhexylglycerin is a monoether of glycerin and 2-ethylhexanol. The body cleansing composition of the present invention may contain one of phenoxyethanol and ethylhexylglycerin alone or in combination of the two as component (D).

[0038] In the present invention, the phenoxyethanol and ethylhexylglycerin can be prepared according to known manufacturing methods, or commercially available products for use in cosmetics, quasi-drugs, etc.

[0039] The content of component (D) shall be 0.01 to 1% by mass relative to the total amount of the body cleansing composition. If the content of component (D) is within this range, the massage effect on the scalp in a short time will be further improved. From this viewpoint, the content of component (D) is preferably 0.1% by mass or more, and more preferably 0.2% by mass or more. Furthermore, the content of component (D) is preferably 0.8% by mass or less, and more preferably 0.6% by mass or less.

[0040] [Component (E)] The detergent composition of the present invention may further contain component (E). Component (E) used in the present invention is cationized cellulose, which is cellulose to which a cationic functional group has been conjugated.

[0041] The degree of cationization of cationized cellulose is preferably in the range of 0.1 to 2.0 meq / g. By setting the degree of cationization to 0.1 meq / g or higher, the lack of stickiness when used on the skin and the massage effect on the scalp in a short time are further improved. From this viewpoint, it is even more preferable to set the degree of cationization to 0.2 meq / g or higher. Furthermore, by setting the degree of cationization of cationized cellulose to 2.0 meq / g or lower, the lack of a squeaky feeling when used on the hair is further improved. From this viewpoint, it is even more preferable to set the degree of cationization to 1.8 meq / g or lower.

[0042] The degree of cationization of cationized cellulose, which is component (E), can be easily calculated if its chemical structure is clear. However, even if the structure, such as the monomer ratio, is unknown, it can be calculated from the measured value of N content using the Kjeldahl method. The degree of cationization shown in this invention is calculated based on the value measured by the second method of nitrogen determination, a general test method of cosmetic raw material standards, which is the Kjeldahl method. The unit of degree of cationization, meq / g, indicates the number of milliequivalents of N cation groups per gram of sample.

[0043] The weight-average molecular weight of cationized cellulose is preferably in the range of 50,000 to 3,000,000. A weight-average molecular weight of 50,000 or more further improves the lack of squeaky feeling when used on hair. From this viewpoint, a weight-average molecular weight of 100,000 or more is even more preferable. Furthermore, a weight-average molecular weight of 3,000,000 or less further improves the lack of stickiness when used on skin and the massage effect on the scalp in a short time. From this viewpoint, a weight-average molecular weight of 2,000,000 or less is even more preferable.

[0044] The weight-average molecular weight of the cationized cellulose shown in this invention was measured using GPC-MALLS. The sample solution, diluted with a mobile phase containing approximately 1,000 ppm of polymer purity, was measured at a wavelength of approximately 633 nm using a multi-angle light scattering detector with a TSK-GEL® α column (manufactured by Tosoh Corporation) and a 0.5 mol / L sodium perchlorate solution as the mobile phase. Polyethylene glycol with a known molecular weight was used as the standard.

[0045] Examples of commercially available products containing ingredient (E) include "Leoguard LP, GP, MGP, KGP" manufactured by Lion Corporation, "UCARE LR-30M, JR-400, JR-30M" manufactured by Dow Chemical Japan Ltd., and "Kachinaru HC-100, LC-100, HC-200, LC-200" manufactured by Toho Chemical Industry Co., Ltd.

[0046] As component (E), one or more types selected from the above cationic polymers can be used.

[0047] The content of component (E) shall be 0.01 to 2% by mass of the total amount of the body cleansing composition. If the content of component (E) is within the above range, the lack of squeaky feeling when used on hair and the massage effect on the scalp in a short time will be further improved. From this viewpoint, the content of component (E) is preferably 0.1% by mass or more, and more preferably 0.2% by mass or more. Furthermore, the content of component (E) is preferably 1.5% by mass or less, and more preferably 1.2% by mass or less.

[0048] [Other ingredients] The body cleansing composition of the present invention may further contain other optional components, as long as they do not impair the effects of the invention. The content of the optional components is preferably 30% by mass or less, and more preferably 20% by mass or less, based on the total amount of the body cleansing composition.

[0049] Other optional ingredients include, for example, oils and fats such as vegetable oils and animal oils; hydrocarbon oils such as squalane, liquid paraffin, and hydrogenated polyisobutene; higher alcohols such as cetyl alcohol, stearyl alcohol, and cetostearyl alcohol; silicones such as cyclic silicones, dimethylpolysiloxane, and amino-modified polysiloxane; ester oils such as 2-ethylhexyl palmitate, caprylic / capric triglyceride, and isopropyl myristate; anionic surfactants such as polyoxyethylene lauryl ether sulfate, α-olefin sulfonate, fatty acid soap, and N-acyl amino acid surfactants other than ingredient (A); cationic surfactants such as stearyltrimethylammonium chloride, benzalkonium chloride, and cocoyl arginine ethyl PCA; and polyoxyethylene alkyl ethers and polyglycerin fatty acid ethers. Nonionic surfactants such as telates, polyoxyethylene glycerin fatty acid esters, fatty acid alkanolamides (e.g., lauric acid diethanolamide), and fatty acid alkylene glycol esters (e.g., lauric acid monobutylene glycol ester); water-soluble polymers other than component (C), such as hydroxyethylcellulose, polyethylene glycol, polyvinyl alcohol, and carboxyvinyl polymer; solvents such as ethanol, propylene glycol, and glycerin; pH adjusters such as sodium hydroxide, potassium hydroxide, monoethanolamine, triethanolamine, hydrochloric acid, sulfuric acid, citric acid, succinic acid, malic acid, lactic acid, and tartaric acid; antioxidants such as tocopherol; preservatives such as sodium benzoate and 1,3-butylene glycol; and humectants, polysaccharides, amino acids, peptides, fragrances, and colorants may be included as appropriate.
