  The degree of cationization of the cationized β-glucan of the present invention is preferably 0.1 to 2.0. When the degree of cationization of the cationized β-glucan of the present invention is less than 0.1, a sufficient conditioning effect may not be obtained when blended into a cosmetic composition or the like. Since the cationization reaction requires a long production time and a large amount of cationizing agent, the production is difficult, and the conditioning performance that meets the high degree of cationization cannot be obtained. The degree of cationization of the β-glucan of the present invention is more preferably 0.15 to 1.5, and most preferably 0.2 to 1.0. In the present invention, the degree of cationization means the average value of the number of cationic groups per monosaccharide unit. In the case of the cationized β-glucan of the present invention, the upper limit of the degree of cationization is 3.0. .

  The cationized β-glucan of the present invention can be produced by a method of cationizing β-glucan with a cationizing agent, a method of adding cationized glucose to β-glucan, a method of polymerizing cationized glucose, etc. Since production is easy, it is preferable to produce β-glucan by a method of cationizing with a cationizing agent.

  In the case where the cationized β-glucan of the present invention is produced by a method of cationizing β-glucan with a cationizing agent, the β-glucan is a glucose unit other than the units represented by the general formulas (1a) to (4a). However, β glucan consisting of at least one unit selected from the group consisting of units represented by the general formulas (1a) to (4a) other than the molecular terminals is preferable. As such β-glucan, β-glucan derived from cereals, β-glucan derived from microorganisms, β-glucan derived from basidiomycetes, etc. are known, and extracted from cereals, microorganisms or basidiomycetes containing β-glucan. That's fine. The extraction method of β-glucan is not particularly limited, and it may be extracted by adding an extraction solvent to cereals, microorganisms or basidiomycetes that are raw materials for extraction. As the extraction solvent, water, a salt solution, an aqueous acid solution, an aqueous alkaline solution, an organic solvent, or a mixed solvent of two or more types can be used. Moreover, extraction efficiency can also be improved by using together the enzyme which decomposes | disassembles a cell wall. The extract can be purified by purifying the extract itself in a solid-liquid separation, or a liquid or solid obtained by concentrating β-glucan extracted from the extract by a known method, or purifying the extract by a known method. It can be used in any form, such as liquids and solids that have been raised, in any form, and in any purity. It is also possible to use what is present.

  Among these β-glucans, cationized β-glucan having high water solubility and easy cationization, high conditioning effect on hair and skin, and antibacterial properties can be obtained. Therefore, the β-glucan is represented by the general formula (1a). Β-glucan comprising the unit represented by (4a) and the unit represented by (4a) are preferable, and the molar ratio of the unit represented by (1a) to the unit represented by the general formula (4a) is preferably 1-2. 1.2 to 1.4 is more preferable. A β-glucan composed of only the unit represented by the general formula (1a) is represented by β-1,3-glucan, a unit represented by the general formula (1a) and a β-glucan composed of the unit represented by (4a). Sometimes referred to as β-1,3-1,6-glucan. β-1,3-1,6-glucan can be obtained from black yeast (genus Aureobasidium), for example. In the present invention, a group in which hydrogen atoms of some hydroxyl groups of β-glucan composed of the unit represented by the general formula (1a) and the unit represented by (4a) are represented by the general formula (5). The cationized β-glucan substituted with is sometimes referred to as cationized β-1,3-1,6-glucan.

  When the cationized β-glucan of the present invention is produced by a method of cationizing β-glucan with a cationizing agent, the cationizing agent can react with a cationic group and a hydroxyl group of β-glucan in the molecule. As long as it has two groups with the group and becomes a group represented by the general formula (5) after the reaction, the type is not limited, but since it can be obtained at a low price, the following general formula (6) or (7) A cationizing agent represented by:

［式中、Ｒ^１９は、炭素数１〜４のアルキレン基を表し、Ｒ^１５〜Ｒ^１７及びＸは、一般式（５）と同義である。］

^{Wherein, R 19} represents an alkylene group having 1 to 4 carbon ^atoms, R 15 ^{to R 17} and X are as in formula (5) interchangeably. ]

R ^{19 in the} general formula (6) represents an alkylene group having 1 to 4 carbon atoms. Examples of such an alkylene group include a methylene group, an ethylene group, a propylene group, a butylene group, an isopropylene group, and an isobutylene group. Among these, a methylene group is preferable because raw materials are easily available. Moreover, R < ¹⁵ > -R < ¹⁷ > and X of General formula (6) are synonymous with General formula (5).

［式中、Ｙはハロゲン原子を表し、Ｒ^１５〜Ｒ^１８及びＸは、一般式（５）と同義である。］

[Wherein, Y represents a halogen atom, and R ^{15 to} R ¹⁸ and X have the same meaning as in general formula (5). ]

Y in the general formula (7) represents a halogen atom. As a halogen atom, a fluorine atom, a chlorine atom, a bromine atom, and an iodine atom are mentioned, for example. Among these, a chlorine atom and a bromine atom are preferable, and a chlorine atom is more preferable because it is easily available as a production raw material. Moreover, R < ¹⁵ > -R < ¹⁸ > and X of General formula (7) are synonymous with General formula (5).

  The cationizing agent represented by the above general formula (6) has an epoxy group as a reactive group that reacts with the hydroxyl group of β-glucan. On the other hand, in the cationizing agent represented by the general formula (7), the halogen atom represented by Y reacts with the hydroxyl group of β-glucan. Although any cationizing agent can be cationized, the cationizing agent represented by the general formula (7) is represented by the general formula (6) with little generation of impurities because a compound containing Y is generated as an impurity. The cationizing agent is preferred.

  The cationization reaction using the cationizing agent may be performed by a known method. For example, when the cationizing agent represented by the general formula (6) is used, water, the cationizing agent, and β-glucan are mixed. The cationization reaction proceeds by adding and mixing an alkali catalyst such as sodium hydroxide or potassium hydroxide as a catalyst. In order to accelerate the reaction, a water-soluble solvent such as methanol, ethanol, isopropanol, acetone, or acetonitrile may be added. In the case of using a water-soluble solvent, the ratio with water is not particularly specified, but water / water-soluble solvent = 1/9 to 9/1 is preferable because the effect of promoting the reaction is high, and water / water-soluble solvent = 2/8 to 7/3 is more preferable. What is necessary is just to set the quantity of the cationizing agent to be used suitably according to the cationization degree of the target cationized β-glucan.

  The form of the cationized β-glucan of the present invention is not particularly limited, and may be any of water, a water-soluble organic solvent, a liquid using water and a water-soluble organic solvent, or a solid from which the solvent is removed. Any solid form may be used, and the liquid cationized β-glucan solvent may be removed to obtain a solid form. In order to further increase the purity, it is preferable to purify liquid cationized β-glucan by dialysis or the like. In the case of a liquid, the concentration may be adjusted so that the cationized β-glucan of the present invention is 0.01 to 50% by mass, preferably 0.1 to 30% by mass.

  Next, the cosmetic composition containing the cationized β-glucan of the present invention will be described. In the present invention, the cosmetic composition containing the cationized β-glucan of the present invention may be referred to as the cosmetic composition of the present invention. The blending amount of the cationized β-glucan of the present invention in the cosmetic composition of the present invention varies depending on the type and use of the cosmetic composition of the present invention, and is not particularly limited.

EXAMPLES Hereinafter, although an Example demonstrates this invention further, this invention is not limited by these Examples. Unless otherwise specified, “parts” and “%” in the examples are based on mass.
[Production of cationized β-glucan 1]
In a 200 ml flask equipped with a stirrer, 25 g of water, 125 ml of isopropyl alcohol, β-1,3-1,6-glucan extracted from fermentation broth by black yeast (Aureobasidium spp.) [Mass average molecular weight 310000, The molar ratio of the unit represented by (1a) to the unit represented by general formula (4a) is 2.26 g of powder of 1.3], 5 g of sodium hydroxide as a catalyst, and glycidyltrimethylammonium chloride as a cationizing agent. 2.12 g (10 mmol) was added and stirred at 25 ° C. for 30 minutes. Thereafter, the temperature in the system was raised to 50 ° C., and the reaction was continued by stirring at 50 ° C. for 5 hours. After completion of the reaction, the system was neutralized with acetic acid, and the stirring was stopped. When the mixture was allowed to stand for 3 hours with natural cooling, the cationized β-glucan obtained by the cationization reaction was precipitated in the system. The precipitate was filtered, washed with isopropyl alcohol, and dried to obtain a powder of cationized β-glucan 1. The degree of cationization of cationized β-glucan 1 was 0.47.

  In addition, the used β-1,3-1,6-glucan contains water, and corresponds to 1 mol of glucose unit at 226 g and 10 mmol of glucose unit at 2.26 g. The purity of β-1,3-1,6-glucan was determined by measuring the water content by the Karl Fischer method and measuring the glucose unit content by the phenol-sulfuric acid method described below. The degree of cationization was determined from the molar concentration of the glucose unit in the measurement sample determined by the following phenol-sulfuric acid method and the molar concentration of the cationic group in the measurement sample determined by the measurement of the following colloid titration method.

<Measurement method of monosaccharide unit content>
The monosaccharide unit content in the sample was determined by a general phenol-sulfuric acid method (based on Methods in Carbohydrate Chemistry vol.1, pp. 380-394) as a quantitative method for sugar. Glucose was used as a standard substance for the calibration curve.

<Measurement method of cationic group content>
A 0.1% by mass toluidine blue aqueous solution was used as an indicator, and titration was performed with potassium polyvinyl sulfate (N / 400), and the cationic group content in the sample was determined from the titration amount.

<Calculation of degree of cationization>
Cation degree = cationic group content in sample / monosaccharide unit content in sample

[Production of Cationized β-Glucan 2-4]
Except having changed the usage-amount of glycidyl trimethyl ammonium chloride, operation similar to the manufacture example of the cationized beta glucan 1 was performed, and the cationized beta glucan 2-4 was obtained. Table 86 below shows the mass average molecular weight and degree of cationization of the cationized β-glucans 2-4. The degree of cationization was calculated by the above method.

[Production of cationized β-glucan 5]
The same procedure as in the production example of cationized β-glucan 1 was performed except that β-1,3-glucan (mass average molecular weight 320,000) was used instead of β-1,3-1,6-glucan. Β-glucan 5 was obtained. Table 86 below shows the mass average molecular weight and degree of cationization of cationized β-glucan 5.

[Test polymer of comparative example]
As comparative examples, cationized hyaluronic acid, cationized cellulose, cationized β guar gum, and β-1,3-1,6-glucan were used. Each mass average molecular weight and degree of cationization are shown in Table 86 below. Since cationized hyaluronic acid is difficult to measure the cationic group content by the above method, the nitrogen content of the sample is measured, and the nitrogen content and monosaccharide units (glucuronic acid unit and N-acetoglucosamine unit) are measured. From the content, the degree of cationization was calculated.

  The test polymers of Examples 1 to 5 and Comparative Examples 1 to 4 were subjected to a chargeability test, a static electricity generation test, and a friction coefficient measurement by using hair as follows. The results are shown in Table 89.

[Preparation of test hair]
Test hair was prepared by the following steps. In addition, the test hair of only the washing | cleaning process was made into healthy hair, and the test hair which repeated the damage process 5 times was made into damaged hair.
<Washing process>
1 g of hair of the same person having a length of 10 cm was washed by stirring in 40 ml of an aqueous solution of 2.5% by mass nonionic surfactant (sodium polyoxyethylene lauryl ether sulfate) at 40 ° C. for 30 minutes. Rinse for a minute and then dry with a dryer.
<Damage process>
After damaging the hair by putting 1 g of normal hair in 200 ml of a mixture of 4.5% by mass aqueous hydrogen peroxide and 2.5% by mass aqueous ammonia and stirring at 25 ° C. for 30 minutes, Rinse with running water for 2 minutes and dry with a dryer.
<Adsorption process>
1 g of damaged hair is immersed in 200 ml of 0.1% by mass test polymer at 40 ° C. for 20 minutes, rinsed with running water for 2 minutes, and then dried with a dryer.

[Chargeability test]
Using a static electricity meter (model FMX003, manufactured by Simco Japan), the surface potential of the test hair was measured under the conditions of a temperature of 22 ° C. and a humidity of 25%. The measurement was performed 10 times on different parts of the test hair, and the average value was defined as the surface potential. Normally, healthy hair is known to be positively charged and damaged hair is negatively charged, and the more the cationic substance adsorbs to the damaged hair, the more positively charged. That is, the larger the amount of adsorption, the higher the treatment effect.

[Static generation test]
The test hair was rubbed against a polyethylene terephthalate resin sheet (PET sheet) 30 times under the conditions of a temperature of 22 ° C. and a humidity of 25% to generate static electricity on the test hair. FMX003) was used to measure the static electricity of the test hair under the conditions of a temperature of 22 ° C. and a humidity of 25%. The smaller the amount of static electricity, the smaller the amount of static electricity generated due to external influences such as brushing, and the better the unity of hair by brushing and the like, the easier it is to set.

[Friction coefficient measurement]
The average friction coefficient of the test hair was measured under conditions of a temperature of 22 ° C. and a humidity of 25% using a friction tester (manufactured by Kato Tech, model KES-SE). In the test, 20 test hairs attached to a glass plate were used, a weight of 25 g, a moving speed of 1 mm / second, and a fingerprint type sensor (made of metal) was used as a sensor. The lower the average coefficient of friction, the better the feel and fingering of the hair.

  From the results in Table 89, it can be seen that the cationized β-glucan of the present invention has a high conditioning effect on the hair. That is, in Table 89, it can be seen that all of the cationized β-glucans of the present invention are positively charged in the chargeability test and fall down, have a large amount of adsorption to damaged hair, and have a high treatment effect. Is shown. From the static electricity generation test, all of the cationized β-glucan of the present invention generates little static electricity, and by blending it with shampoo or rinse, it is easy to set the hair by brushing etc. . From the results of the friction coefficient measurement, it is shown that the cationized β-glucan of the present invention has a great effect of improving the touch and fingering of damaged hair. These effects are particularly remarkable in the cationized β-1,3-1,6-glucan of the present invention.

Evaluation with lotion Using the lotion formulated according to the formulation shown in Table 90 below based on Formulation Example 122 above, the panelists (10 persons) actually used the skin to feel moist and fluffy (the skin has elasticity). A sensory evaluation was performed on the feeling of freshness. The evaluation was made by calculating the average score of 10 people according to the following evaluation point criteria. The results are shown in Table 92.

(Evaluation criteria for moist feeling)
5 points: moist feeling 4 points: somewhat moist feeling 3 points: normal 2 points: no moist feeling 1 point: no moist feeling (evaluation point standard for fluffy feeling)
5 points: Fluffy 4 points: Slightly fluffy 3 points: Normal 2 points: Slightly fluffy 1 point: Fluffy

Evaluation with facial cleansers Based on prescription example 120, using facial cleansers formulated according to the prescription in Table 91 below, the actual use by professional panelists (10 persons) resulted in a moist and soft feeling after use (the skin has elasticity). A sensory evaluation was performed on the feeling of freshness. The evaluation was made by calculating the average score of 10 people based on the same evaluation criteria as the evaluation with the lotion.

  From the results in Table 92, it can be seen that the cationized β-glucan of the present invention has a high conditioning effect on the skin. That is, in Table 92, both the lotion and the face wash formulated with the cationized β-glucan of the present invention are excellent in the moist and fluffy feeling of the skin after use. , 3-1,6-glucan.

The antibacterial property was measured by the following method using the test polymers of Examples 1 to 5 or Comparative Examples 1 to 4 and a general phenoxyethanol as an antibacterial agent of the cosmetic composition. The results are shown in Table 93.
[Antimicrobial test method]
The test sample was diluted with sterilized water to prepare a test solution having a test sample concentration of 10240 μg / ml. Thereafter, the test solution was repeatedly diluted 2-fold with a bouillon medium (Mueller Hinton medium) to prepare test solutions having a total of 11 levels of test sample concentrations of 10 to 10240 μg / ml. Using the bacterial solution which had been pre-cultured in broth medium, the bacterial solution which had been adjusted to 10 ⁷ levels, placed in 0.01ml microplate, test solutions of various concentrations and stirred well with adding 0.2 ml. This mixed solution was cultured at 37 ° C. for 24 hours. After completion of the culture, the turbidity of the microplate was measured, and the lowest concentration that inhibited the growth of the test bacteria was defined as the minimum growth concentration (MIC). The lower the minimum growth concentration, the higher the antibacterial property. In the test, Staphylococcus aureus NBRC12732 was used.

  From the results of Table 93, it can be seen that among the cationized β-glucans of the present invention, the cationized β-1,3-1,6-glucan of the present invention has high antibacterial properties.

  Since the cationized β-glucan of the present invention has a high conditioning effect, the cationized β-glucan can be suitably used in a cosmetic composition for the purpose of washing and treating the body and hair such as shampoo, rinse, body soap, and facial cleanser. . Furthermore, since the cationized β-1,3-1,6-glucan of the present invention has high antibacterial properties, households that sterilize medical detergents, dishes, etc. for the purpose of disinfecting and cleaning medical instruments and affected areas.
