Description

  The present invention is a cation-modified psyllium seed gum having good adsorptivity to hair and skin, excellent foaming, good foam quality, good salt resistance and good water retention when blended in a cosmetic composition. And a cosmetic composition containing the same, particularly a hair treatment composition.

  A hair treatment composition for the purpose of washing contains a conditioning agent for damaging the hair due to tangling of the hair during washing and rinsing, and for improving the feel after washing. For this reason, it is essential that the conditioning agent be adsorbed on the hair, and as the substance that gives the conditioning effect, the hair surface is negatively charged, so that a cationic polymer having an adsorption action mainly based on ionicity is used. ing. As the cationic polymer, a water-soluble polymer obtained by introducing a quaternary nitrogen-containing group into a polysaccharide such as a cellulose derivative, guar gum or starch, a dialkyl diallylammonium salt polymer, or the like is used.

For example, Patent Document 1 discloses that a cation-modified cellulose derivative having a quaternary nitrogen-containing group introduced therein is used for shampoos and hair cosmetics.
Patent Document 2 discloses that a cation-modified starch having a quaternary nitrogen-containing group introduced therein is used for hair care products such as shampoos and rinses.

Patent Document 3, Patent Document 4, and Patent Document 5 disclose, in Patent Document 6, a cation-modified guar gum obtained by cation-modifying a guar gum having a main chain mannose and side chain galactose belonging to galactomannan polysaccharide of 2: 1. Is a cation-modified locust bean gum obtained by cationic modification of locust bean gum having a main chain of mannose and side chain galactose of 4 to 1, and Patent Document 7 discloses a galactomannan polysaccharide having different composition ratios of guar gum and mannose and galactose. Cationic modified polygalactomannans obtained by cationically modifying bean gum have been shown to be used in hair care products such as shampoos and rinses and body soaps. However, in the case of cation-modified guar gum using guar gum, the characteristics of guar gum appear even after cation modification, and the cation-modified psyllium seed gum of the present invention has adsorptivity to hair and skin, foaming, foam quality, salt resistance, water retention, etc. When compared with hair treatment compositions and skin cosmetic compositions, it is different in feel. That is, the cationic guar gum has a drawback that although it has little feeling of wrinkling after drying, it has a small amount of adsorption and a weak conditioning effect at the time of rinsing. In recent years, with the diversification of fashion, the use of hair colors and hair dyes has increased, resulting in significant damage to the hair. Even with cation-modified guar gum, damaged hair lacks flexibility and is stiff. There is a problem. Similarly, in the case of cation-modified locust bean gum using locust bean gum, the function is different from that of the cation psyllium seed gum of the present invention, and there is a problem that damaged hair lacks flexibility and shows a feeling of stiffness.

Further, Patent Document 8 uses guar gum and locust bean gum as galactomannan polysaccharides, and cation-modified cation-modified galactomannan polysaccharides that have been degraded by enzymes and the like and then reduced in molecular weight. Patent Document 9 discloses guar gum as galactomannan polysaccharides. The cation-modified galactomannan polysaccharide is shown in which a locust bean gum is used and then a cation modification is performed after a hydroxyalkyl modification followed by a cation modification, and the structure of the main chain and the side chain is psyllium seed gum of the present invention. Compared with the cation-modified psyllium seed gum of the present invention due to the difference in viscosity due to the fact that it is different from the presence or absence of low molecular weight, the adsorptivity to the hair and skin, foaming, foam quality, salt resistance, water retention are That's not enough.

  On the other hand, in the case of a skin cosmetic composition, soaps and anionic surfactants are widely used, but when washing, the oily and fat components of the skin are removed more than necessary, and there is a feeling of tension against the skin. There is also a problem that arises. From the effect of eliminating such inconvenience and imparting a moist feeling, a skin cosmetic composition such as a body cleaning agent is blended with a conditioning agent such as a cationic polymer and a humectant such as glycerin. However, stickiness and sliminess may occur depending on the blending amount in the prescription.

  Further, in Patent Document 10, a shampoo composition containing a copolymer of a dialkyl diallylammonium salt and a cellulose derivative having a quaternary nitrogen-containing group introduced gives a smooth and smooth feeling to the finger as it hangs during hair washing. In addition, it has been shown to give a smooth and smooth finger passage to the hair when rinsed, and to give a good gloss to the hair when finished. Also, by blending these cationic polymers, it is possible to obtain a creamy foam quality, to eliminate the feeling of tension on the skin, and to give a moist feeling to skin cosmetic compositions such as body cleaning agents. Is also blended.

  Furthermore, Patent Document 11 discloses a patent containing psyllium seed gum or a derivative thereof as a binder of a dentifrice composition. Examples of psyllium seed gum derivatives include carboxymethylated compounds, methoxyl or ethoxyl derivatives, hydroxy An alkyl group-modified product is specified, but a cation-modified psyllium seed gum is not described.

As a cosmetic composition using a plant polysaccharide having a high moisturizing effect, low cost and high safety, a cross-linked product composed of galactomannan or a derivative thereof is used as a moisturizing ingredient, and the cross-linked product contains a galactomannan or a derivative thereof having a trivalent or higher polyvalent content. Patent Document 12 discloses a cosmetic composition that is cross-linked with a valent metal ion or mixed with at least one selected from carrageenan and xanthan gum and heat-treated at 50 ° C. or higher. In this document, it is possible to add other polysaccharides, proteins, polyamino acids and derivatives thereof to galactomannan or derivatives thereof, and cationized psyllium seed gum, agar, pectin, alginic acid, etc. It is said that it may be mixed, but when cationized psyllium seed gum is blended in a cosmetic composition, it has good adsorptivity to hair and skin, excellent foaming, good foam quality, and salt resistance. It is not specified that it is good and has good water retention.

The problem to be solved by the present invention is that the conventional cationic polymer has adsorptivity to hair and skin, foaming, foam quality, salt resistance and water retention when blended in a cosmetic composition, and skin cosmetics. An object of the present invention is to provide a compound that eliminates the feeling of firmness and bulkiness of the skin when blended in the composition, and improves the feeling of stickiness and sliminess.

  As a result of intensive studies to solve the above problems, the present inventors have introduced a specific amount of a quaternary nitrogen-containing group into the hydroxyl group contained in the psyllium seed gum, and set the cation charge amount within a specific range. The adjusted cation-modified psyllium seed gum has good adsorptivity to hair and skin in the cosmetic composition, has excellent foaming, good foam quality, and has salt resistance in formulating a cosmetic composition. Has found water retention, and has completed the present invention.

  The cation-modified psyllium seed gum of the present invention, when formulated in a hair treatment composition such as shampoo and rinse, has good adsorptivity to hair and skin, excellent foaming, good foam quality, and good salt resistance. In addition, it has good water retention and also eliminates the feeling of stickiness and bulkiness when added to the skin cosmetic composition, thereby improving the feeling of stickiness and sliminess. In addition, the cation-modified psyllium seed gum with the cation charge amount adjusted to a specific range has salt resistance and water retention in formulating a cosmetic composition, and thus a cosmetic composition that is more comfortable to use than conventional products. Can be provided.

Hereinafter, the present invention will be described in detail.
The psyllium seed gum used in the present invention is a polysaccharide in which a side chain having arabinose, rhamnose, and galacturonic acid as a constituent unit is bonded to main chain xylose. It is a natural plant gum consisting of a husk taken from seeds such as Forskal.
Although this psyllium seed gum generally contains what is marketed, the refinement | purification method and particle size of such psyllium are not specifically limited. Generally, it can be easily obtained as a trade name “Food Made P-100” (manufactured by Shikibo Co., Ltd.) or “refined psyllium seed gum RG-500” (manufactured by MRC Polysaccharide).

  The psyllium seed gum is also slowly hydrated with water to form a clear solution or highly viscous dispersion. At a concentration of 1 wt%, a highly viscous dispersion is formed, and at a concentration of 2 wt%, a clear gel with a gelatinous mass is formed. When a 1 wt% solution is heated to 90 ° C. and cooled, it becomes a solid gel mass.

The cation modification according to the present invention can be carried out by reacting psyllium seed gum with a glycidyl trialkylammonium 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, and is not necessarily limited thereto. For example, after adding C2-C4 alkylene oxide to a part of hydroxyl group contained in psyllium seed gum, it is made to react with the said glycidyl trialkyl ammonium salt or 3-halogeno-2-hydroxypropyl trialkyl ammonium salt. Thus, the cation-modified psyllium seed gum of the present invention can be produced. Also, an inorganic salt, preferably sodium chloride, can be added to prevent aggregation of the psyllium seed gum in the solvent during the reaction. Furthermore, in order to prevent agglomeration of psyllium seed gum, improve dispersibility and increase the reaction rate, the alkali and inorganic salts are added to the reaction solvent and then dissolved or dispersed, and then the psyllium seed gum is added and dissolved or dispersed. Then, it can also be produced by introducing the quaternary nitrogen-containing group.

In the quaternary nitrogen-containing group represented by the chemical formula (1) introduced in the present invention, specific examples of R ₁ and R ₂ include methyl, ethyl and propyl, and those having 1 to 24 carbon atoms Specific examples of R ₃ as the alkyl group include octyl, decyl, dodecyl, tetradecyl, hexadecyl, octadecyl, docosyl, oleyl and the like in addition to the same as R ₁ and R ₂ described above. Specific examples of R ₄ O include an oxyethylene group, an oxypropylene group, and an oxybutylene group. Further, the anion X ^- include Specific examples of other halogen ions such as chlorine ions, bromine ions and iodine ions, methyl sulfate ions, ethyl sulfate ion, an acetate ion.

  The cation-modified psyllium seed gum of the present invention, when formulated in a cosmetic composition, has good adsorptivity to hair and skin, excellent foaming, good foam quality, good salt resistance, and water retention. It is good and excellent as a composition component of a cosmetic composition. For example, when it is blended in a hair treatment composition, it can improve flexibility and feel, and it can be used in a skin cosmetic composition such as a body cleanser. When blended, do not remove skin oil components more than necessary. Therefore, the present invention also relates to these cosmetic compositions containing the cation-modified psyllium seed gum of the present invention.

  The cationic charge amount derived from the quaternary nitrogen-containing group of the cation-modified psyllium seed 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 to the hair and skin will be insufficient, and even if it is actually incorporated into hair treatment compositions such as shampoos, rinses, body cleaners, and skin cosmetic compositions, it is effective. unacceptable. Further, when the charge amount exceeds 3.0 meq / g, even if a hair treatment composition and a skin cosmetic composition containing such a cation-modified psyllium seed gum are used, the foaming deteriorates and becomes sticky during use. A feeling of sensation and a feeling of stickiness are generated, and the feeling of use is deteriorated, and a feeling of finish after use is also unfavorable, such as a feeling of stickiness and stickiness.

The cation charge amount derived from the quaternary nitrogen-containing group of the cation psyllium seed 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 psyllium seed gum. . Usually, the nitrogen content derived from a quaternary nitrogen-containing group can be obtained by the Kjeldahl method (former cosmetic raw material standard, general test method, nitrogen determination method, second method) and calculated from the measured value, but the psyllium seed used in the present invention Since the gum contains the nitrogen content of the protein, the value obtained by subtracting the nitrogen content derived from the psyllium seed gum used in the present invention from the nitrogen content in the cation-modified psyllium seed gum of the present invention determined by the Kjeldahl method is Nitrogen content derived from quaternary nitrogen-containing groups 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. When the nitrogen content of the product of the present invention obtained by cation-modifying psyllium seed gum with a group was 1.97% as a result of measurement by the Kjeldahl method, the cation charge amount of this substance was expressed by the following formula: Desired. The psyllium seed gum used in the present invention usually contains about 0.09% nitrogen.

  The blending amount of the cation-modified psyllium seed 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, less than 0.05% by mass, based on 100% by mass of the entire composition. However, the adsorbed amount to the hair and skin becomes insufficient, and in fact, even if it is blended into a hair treatment composition such as a shampoo, rinse, body cleaning agent, or skin cosmetic composition, no effect is observed. If it exceeds 5% by mass, a feeling of stickiness and stickiness will be produced during use, and the flexibility will deteriorate and the feeling of use will tend to deteriorate.

  In addition, the hair treatment composition of the present invention includes various cationic water-soluble polymers and amphoteric water-soluble polymers for improving the conditioning effect and foaming, foam quality, salt resistance, water retention and setting properties. Although it can be used in combination, the blending amount is in a range that does not impair the flexibility of the cation-modified psyllium seed gum with respect to the hair, and the total composition is 100% by mass, preferably 5% by mass or less. There is a tendency for a feeling of stickiness and stickiness to occur, and for the flexibility to deteriorate and the feeling of use to deteriorate. Furthermore, in the skin cosmetic composition, a feeling of sliminess is generated and the feeling of use becomes worse.

From the composition shown in the blank (F) of Table 2 as a shampoo of the formulations S1 to S7 and comparative products C1, C2 and C3 of each of the present invention products prepared in the aforementioned 5-a to 5-f. Each shampoo was used to wash 15 g of hair strands (total length: 180 mm) with 1.0 g each. Thereafter, it was rinsed with running water, left in a constant temperature and humidity (20 ° C., 40% RH) atmosphere for 24 hours, and then naturally dried. Thereafter, the firmness of the hair was measured with a pure bending tester (KES-FB2-S, manufactured by Kato Tech Co., Ltd.). The results are shown in Table 3. In addition, after heating the component (12) in the blank (F) of Table 2 to 60 ° C., adding a component (5) to (7) and stirring to make the blank uniform, then cooling it at 30 to 40 ° C. Components (8) to (11) were added and mixed uniformly.

On the other hand, the comparative product C1 containing the cation-modified psyllium seed gum of Sample No. 7 whose cation charge amount value is lower than the range of the present invention and the comparative product C3 containing the unmodified psyllium seed gum had the same results as the blank. This is because when an unmodified psyllium seed gum and a cation-modified psyllium seed gum having a cation charge value lower than the range of the present invention are washed out and used as a product, the adsorptive capacity based on ionicity cannot be obtained for the hair. It is considered that the effect was not obtained because there was little adsorption of the seed gum on the hair. On the other hand, the product of the present invention in which psyllium seed gum is cation-modified has adsorption ability based on ionicity to the hair, so that flexibility can be obtained in a washing product such as a shampoo. As a result, it was possible to obtain effects such as an improvement in hysteresis value and a soft feel to the hair when touched by hand. Therefore, it has been found that the cation-modified psyllium seed gum of the present invention exhibits its effect sufficiently even when it is blended into a wash-out product such as shampoo and rinse.
