  The hair treatment composition for the purpose of washing contains a conditioning agent for damaging hair entangled during washing and rinsing and for improving touch after washing. As a substance that imparts a conditioning effect, since it is essential to adsorb to the hair, a cationic polymer having an adsorption action mainly based on ionicity is used. Among them, a cation-modified cellulose derivative has been used for a long time, and Patent Document 1 discloses that a cation-modified cellulose derivative having a quaternary nitrogen-containing group introduced into a shampoo or hair cosmetic is used. Furthermore, Patent Document 2 shows that cation-modified guar gum into which a quaternary nitrogen-containing group is introduced is used in hair care products such as shampoos and rinses for the purpose of improving the finished feeling. However, the cation-modified cellulose derivative shows some conditioning effect during rinsing, but the feeling of deterioration such as wrinkle feeling after drying is recognized, and the cation-modified guar gum has less wrinkling feeling after drying, but the conditioning effect during rinsing Deficiencies are recognized.

  For the purpose of improving these, cation-modified tara gum obtained by adjusting the amount of cationic charge within a specific range has come to be used. Patent Document 3 discloses hair care products such as shampoos and rinses, body cleaning agents, and the like. When used in skin cosmetics, it is shown that the conditioning effect during rinsing is improved compared to cation-modified guar gum, the foam quality and the squeaky feeling and dryness after drying are improved, and a good feeling of use is obtained. ing. Furthermore, Patent Document 4 and Patent Document 5 provide that when a cationically modified tara gum is used in a detergent composition such as a shampoo, a detergent composition having excellent foaming power and conditioning properties is provided.

  In recent years, with the diversification of fashion, the use of hair colors and hair dyes has increased, and as a result, the hair has been significantly damaged, so that the conditioning effect of the conditioning agent, particularly the slipping property during use, has become important. When cation-modified tara gum, which was invented to improve the conditioning effect during rinsing and to improve the feel after drying, or a combination system of cation-modified tara gum and a specific cationic polymer, is used for such damaged hair, Although there are certain effects such as improvement of foam quality and conditioning effect at the time of rinsing, it is not sufficient. Furthermore, the feeling of finish after fingering and after drying is not fully satisfactory. Moreover, even when blended in a skin cosmetic composition, the feeling of use is not sufficiently satisfactory, and there is also a problem in appearance due to water-insoluble matter.

  In such a situation, the present inventors have improved the slipperiness to wet hair when blended with a conventional cation-modified tara gum hair treatment composition, and also improved the finished feeling after drying, and the skin cosmetics. The present inventors have intensively studied compounds that improve the foam quality when blended with the composition and the feeling after use. As a result, mannose and galactose having a galactose unit as a side chain in a main chain having a galactose content of 90% by mass or more and a turbidity of a 1% by mass aqueous solution of 15% or less and having mannose as a structural unit. A specific amount of a quaternary nitrogen-containing group is introduced into a galactomannan polysaccharide (hereinafter also referred to as purified tara gum) having a composition ratio of 3 to 1, and the cation charge amount is adjusted to a specific range. The turbidity of a 1% by weight aqueous solution of cation-modified purified tara gum after introducing a specific amount of quaternary nitrogen-containing group is 15% or less, and has excellent properties as a conditioning agent in cosmetic compositions, and is wet As a result, the present inventors have found that slipperiness to hair, improvement of foaming and foam quality, and improvement in touch can be improved.

The content of galactomannan in which the main chain is composed of galactose units as side chains and the composition ratio of mannose and galactose is 3: 1 is 90% by mass or more, and the turbidity of a 1% aqueous solution is 15% or less. A part of the hydroxyl group of the purified tara gum is substituted with a quaternary nitrogen-containing group represented by the following chemical formula (1), and the cation charge amount derived from the quaternary nitrogen-containing group is 0.1 to 3.0 meq / Further, the present invention relates to a cation-modified purified tara gum having a turbidity of 15% or less of a 1% aqueous solution of cation-modified tara gum after introducing a specific amount of a quaternary nitrogen-containing group into the purified tara gum.

  The cation-modified purified tara gum of the present invention is used as a conventional conditioning agent for hair when used when used in a hair treatment composition such as shampoo and rinse because the water-insoluble matter in the crude tara gum is reduced. The galactomannan content is less than 90% by mass of the crude tara gum, which is cation-modified and has a feel superior to that of a cation-modified tara gum (hereinafter also referred to as cation-modified crude tara gum). In addition, when the cation-modified purified tara gum of the present invention is blended in a skin cosmetic composition such as a body cleaning agent, it improves foaming and improves foam quality and gives a good finish. Therefore, it is possible to provide a cosmetic composition that is more comfortable to use than conventional products. Furthermore, since the viscosity stability is superior to the conventional cation-modified crude tara gum, which is a conventional cation-modified tara gum, a cosmetic composition having excellent stability can be provided.

  The tara gum used in the present invention is a nonionic polysaccharide having a mannose-containing main unit, a galactose unit as a side chain, and a composition ratio of mannose and galactose of 3 to 1, It is a natural water-soluble gum obtained from the endosperm part of the seed of cod (Caesalpinia Spinosa), a naturally occurring legume plant, and is generally called Tara gum. In the present invention, the crude tara gum obtained from the endosperm portion of the cod seed has a galactomannan content of 90% by mass or more, preferably 96% by mass or more, and the turbidity of a 1% by mass aqueous solution is 15% or less, Preferably, tara gum purified to 8% or less is used.

  One method for purifying crude tara gum so that the content of galactomannan is 90% by mass or more and the turbidity of a 1% by mass aqueous solution is 15% or less is crude tara gum having a galactomannan content of less than 90% by mass. Is dissolved in water to obtain an aqueous solution, impurities are removed by filtration, the filtrate is reprecipitated in an organic solvent, and the precipitate is dried. Alternatively, it can also be obtained by grinding only the central part of the endosperm obtained by removing the outer part including the seed coat.

  In addition, the tara gum having a composition ratio of mannose to galactose of 3 to 1 forms a gel with an aqueous solution of carrageenan and xanthan gum, whereas fenugreek gum having a composition ratio of mannose to galactose of 1 to 1 or 2 It is a well-known fact that the rheology of an aqueous solution differs depending on the composition ratio of mannose and galactose, even if the same galactomannan polysaccharide does not form a gel with a one-to-one guar gum.

  The cation-modified purified tara gum according to the present invention has a content of galactomannan having a composition ratio of mannose and galactose of 3 to 1 obtained by purifying crude tara gum of 90% by mass or more, and a turbidity of an aqueous 1% by mass solution. It can be produced by reacting 15% or less of purified tara gum with a glycidyltrialkylammonium salt having a quaternary nitrogen-containing group or a 3-halogeno-2-hydroxypropyltrialkylammonium salt. In this case, the reaction is carried out in a suitable solvent, preferably a hydrous alcohol, in the presence of alkali. The introduction of such a quaternary nitrogen-containing group can be performed according to a conventionally known method, but is not necessarily limited thereto. For example, after adding an alkylene oxide having 2 to 4 carbon atoms to a part of the hydroxyl group contained in the purified tara gum having a composition ratio of mannose and galactose of 3 to 1, the glycidyl trialkylammonium salt or 3-halogeno-2 The cation-modified purified tara gum of the present invention can also be produced by reacting with a quaternary nitrogen-containing group of -hydroxypropyltrialkylammonium salt. In addition, an inorganic salt, preferably sodium chloride can be added in order to prevent aggregation of the purified tara gum in the solvent during the reaction. Furthermore, in order to prevent aggregation of the purified tara gum, improve dispersibility and increase the reaction rate, the alkali and inorganic salts were added to the reaction solvent and then dissolved or dispersed, and then the purified tara gum was added and dissolved or dispersed. Thereafter, it can also be produced by introducing the quaternary nitrogen-containing group.

  Furthermore, the crude tara gum having a galactomannan content of less than 90% by mass is cationized by the same method, and then the water-insoluble matter such as the outer skin is removed and purified by a method such as pulverization, classification or filtration. A cation-modified purified tara gum having a galactomannan content of 90% by mass or more and a 1% by mass aqueous solution having a turbidity of 15% or less can be produced.

In the present invention, in the quaternary nitrogen-containing group represented by the chemical formula (1) introduced into the purified tara gum, which is a galactomannan polysaccharide having a composition ratio of mannose and galactose of 3 to 1, the specifics of R ₁ and R ₂ Examples include methyl, ethyl, and propyl. Specific examples of R ₃ as the alkyl group having 1 to 24 carbon atoms include the same as R ₁ and R ₂ above, as well as octyl, decyl, dodecyl, tetradecyl. , Hexadecyl, octadecyl, docosyl and the like. Specific examples of R ₄ O include ethoxy, propoxy, and butoxy. Further, specific examples of the anion X ⁻ include methyl sulfate ion, ethyl sulfate ion, acetate ion, etc. in addition to halogen ions such as chlorine ion, bromine ion and iodine ion.

  The cation-modified purified tara gum of the present invention is adsorbed to hair and skin by cation-modifying purified tara gum having a galactomannan content of 90% by mass or more and a turbidity of a 1% by mass aqueous solution of 15% or less. It is excellent as a blending component of a cosmetic composition because it has a function and imparts good slipperiness. For example, when blended in a hair treatment composition, it follows the finger during rinsing and after drying. The finish feeling is improved, and when incorporated in a skin cosmetic composition such as a body cleanser, the foam quality is improved and the feeling after use is improved. Therefore, the present invention also relates to these cosmetic compositions containing the cation-modified purified tara gum of the present invention.

  The cationic charge amount derived from the quaternary nitrogen-containing group of the cation-modified purified tara gum of the present invention is 0.1 to 3.0 meq / g, more preferably 0.5 to 2.5 meq / g. If the amount of cationic charge is less than 0.1 meq / g, the amount adsorbed on the hair and skin will be insufficient, and in fact, even if it is added to hair treatment compositions such as shampoos, rinses, body cleaners, and skin cosmetic compositions, the effect is recognized. I can't. In addition, when cation-modified purified tara gum with a charge amount of more than 3.0 meq / g is blended with a hair treatment composition and a skin cosmetic composition, foaming worsens during use and a feeling of stickiness and sliminess is produced. The finished feeling after use is unfavorable because it causes a feeling of stickiness and stickiness.

The cation charge amount derived from the quaternary nitrogen-containing group of the cation-modified purified tara gum is the number of equivalents of the quaternary nitrogen-containing group represented by the chemical formula (1) contained in 1 g of the cation-modified purified tara gum. Usually, the nitrogen content derived from the quaternary nitrogen-containing group can be calculated by the Kjeldahl method (former cosmetic raw material standard, general test method, nitrogen determination method, second method) and calculated from the measured values. Since the refined tara gum having a mannose composition ratio of 3 to 1 contains nitrogen, the composition ratio of galactose and mannose used in the present invention is determined from the nitrogen content in the cation-modified refined tara gum of the present invention obtained by the Kjeldahl method. The value obtained by subtracting the nitrogen content derived from 3: 1 purified tara gum is the nitrogen content derived from the quaternary nitrogen-containing group. Specifically, in the quaternary nitrogen-containing group represented by the chemical formula (1), R ₁ , R ₂ and R ₃ are methyl, X ⁻ is a chlorine ion, and n is a quaternary nitrogen containing n = 0. As a result of measuring the nitrogen content of the product of the present invention obtained by cation-modifying purified tara gum by the Kjeldahl method and found to be 1.15%, the cation charge amount of this substance is expressed by the following formula: Desired. The purified tara gum used in the present invention usually contains about 0.05% nitrogen.

具体的に説明すると、日本バイオコン(株)社製ガラクトマンナン測定キットを用い、本発明品に使用する精製タラガム中のガラクトマンナン含有量を測定した場合、検量線より求められたガラクトース含有量への換算係数A*が1384.6であり、ブランクの340nmにおける吸光度が0.276である時、精製タラガムを固形分換算で21.3mg採集し、その試料溶液の340nmにおける吸光度が0.644である例では、ガラクトース含有量は23.9%となる。タラガムはマンノースとガラクトースの組成比が3対１であるから、ガラクトマンナン含有量は95.6%となる。 The galactomannan content in the purified tara gum is a mass percentage of galactomannan contained in 1 g of purified tara gum obtained by purifying crude tara gum, which is a raw material of the cation-modified purified tara gum, in terms of solid content. . The measurement method is as follows. In addition to the measurement based on the absorbance after enzymatic decomposition, the measurement can also be performed by liquid chromatography, thin layer chromatography, or the like. As a measuring method, about 20 mg of a sample is accurately weighed, put in a centrifuge tube, added with 5 mL of ethanol, incubated at 85 to 95 ° C., and then centrifuged. 10.0 mL of 50 mM acetate buffer (pH 4.5) was added to the lower phase separated into an upper phase and a lower phase, and the mixture was heated and then allowed to stand at 40 ° C. for 12 hours. Thereafter, 20 μL of β-mannanase is added and incubated at 40 ° C. for 180 minutes. After incubation, centrifuge, take 0.1 mL of the supernatant, and add 0.2 mL of 50 mM acetate buffer (pH 4.5) and 20 μL of α-galactosidase. Incubate this solution at 40 ° C, add 2.5 mL of 200 mM Tris buffer, add 0.1 mL of β-nicotinamide adenine dinucleotide (0.1 g / 10 mL) and 8 μL of galactose dehydrogenase, and incubate at 40 ° C for 60 minutes. Then, the absorbance at 340 nm of the solution is measured. The galactose content is determined from the obtained absorbance using the following formula. The galactomannan content is calculated from the amount of galactose using the composition ratio of mannose and galactose of the sample.

W: Sampling amount (mg)

Specifically, using a galactomannan measurement kit manufactured by Nippon Biocon Co., Ltd., when measuring the galactomannan content in the purified tara gum used in the present invention product, to the galactose content determined from the calibration curve When the conversion factor A * is 1384.6 and the absorbance at 340 nm of the blank is 0.276, 21.3 mg of purified tara gum is collected in terms of solid content, and in the example where the absorbance at 340 nm of the sample solution is 0.644, the galactose content is 23.9%. Tara gum has a composition ratio of mannose and galactose of 3 to 1, so the galactomannan content is 95.6%.

  The cation-modified purified tara gum and the 1% by mass aqueous turbidity of the purified tara gum indicate the transparency of the aqueous solution and can be measured with a turbidity measuring device. To explain specifically with cation-modified purified tara gum, a 1% by weight aqueous solution of cation-modified purified tara gum prepared in advance with a turbidity measuring device (Poic Integral Sphere Ultraturbidimeter, manufactured by Nippon Seimitsu Optical Co., Ltd.) It is measured by a standard method (white plate method, 10 mm glass cell) of measurement conditions in an integrating sphere type ultra turbidimeter. In addition, as a method of expressing transparency, it is also possible to indicate the transmittance in addition to the turbidity. In this case, both the transmittances of the cation-modified purified tara gum and the 1% by mass aqueous solution of the purified tara gum are 85% or more. Is required.

  The viscosity of the 1% by weight aqueous solution of the cation-modified purified tara gum of the present invention is preferably 10 to 10,000 mPa · s at a measurement temperature of 25 ° C. If the viscosity of a 1% by weight aqueous solution is less than 10 mPa · s, the conditioning effect tends not to be exerted as in the case of the conventional low molecular weight cation-modified galactomannan polysaccharide, and if the viscosity exceeds 10,000 mPa · s, it is wet when used.

  The cation-modified purified tara gum of the present invention is excellent as a blending component of a cosmetic composition. For example, when blended in a hair treatment composition, compared to the conventional cation-modified crude tara gum, the slipperiness and conditioning effect on wet hair is improved, and the finished feeling after drying is also improved. The In addition, in the cation-modified crude tara gum, there are many water-insoluble substances other than galactomannan polysaccharide, which is a natural water-soluble gum, so when used as a skin cosmetic composition, a decrease in feel is observed due to water-insoluble substances. When the cation-modified purified tara gum of the present invention is used, the water-insoluble matter is reduced by purification, so that the touch is not lowered. Moreover, since good foaming can be obtained, it is also excellent as a skin cosmetic composition. Furthermore, the viscosity stability is also superior to conventional products.

  The blending amount of the cation-modified purified tara gum of the present invention with respect to the hair treatment composition or the skin cosmetic composition is preferably 0.05 to 5% by mass, with the total composition being 100% by mass, and if it is less than 0.05% by mass, the conditioning effect is sufficient When the amount exceeds 5% by mass, a feeling of stickiness and stickiness during use is generated, and the slipping property is deteriorated and the feeling of use tends to be deteriorated.

  The hair treatment composition of the present invention can be used in combination with various cationic water-soluble polymers and amphoteric water-soluble polymers in order to improve the conditioning effect. It is within the range that does not impair the slipperiness and conditioning effect of tara gum on the hair and the foam quality, etc., and the total composition is 100% by mass, preferably 5% by mass or less. Tends to worsen and the slipperiness to the hair also tends to deteriorate. Furthermore, in a skin cosmetic composition, the feeling after use tends to be poor, such as a feeling after use becoming heavier or a feeling of being sticky.
