Description

  The present invention, when blended in a cosmetic composition, has good adsorptivity to hair and skin, provides a good conditioning effect, has a hair-removing property due to a good emulsifying power, has excellent salt resistance, and has excellent skin makeup. Cation-modified xanthan gum as a compound that eliminates the feeling of firmness and bulkiness when blended into a cosmetic composition and improves the feeling of stickiness and sliminess, and a cosmetic composition, especially a hair treatment composition, containing the same. Related to things.

  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 also appear after cation modification, and this is because it has a conditioning effect, a moist and moist or refreshing feeling without dryness after drying. It is not sufficient as compared with the cation-modified xanthan gum of the invention, and when blended in a hair treatment composition and a skin cosmetic composition, it differs 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 xanthan gum of the present invention, and there is a problem that damaged hair lacks flexibility and feels stiff.

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, which is a cation-modified galactomannan polysaccharide, which has been modified by hydroxyalkyl modification and then cation modification by using a locust bean gum, has a structure of a main chain and a side chain, which is the xanthan gum of the present invention. Due to the difference and the difference in viscosity due to the presence or absence of low molecular weight, the function and feeling of use as a conditioning agent are not sufficient as compared with the cation-modified xanthan gum of the present invention.

  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 high-concentration, low-viscosity product in which an oxidizing agent is added to an aqueous polysaccharide composition containing a polysaccharide such as xanthan gum having a solid content of more than 20% by weight and a viscosity of less than 9500 mPa · s at 25 ° C. It is specified that the aqueous polysaccharide composition produced by this production method is useful as a fluid additive.
Ngamum is not specified.

Patent Document 12 discloses that a non-granular polysaccharide can be efficiently cationized and an equivalent amount of non-granular polysaccharide is obtained as a synthetic method for obtaining a uniform and good quality of the obtained cationized polysaccharide. The following water-lower alcohol mixed solvent is alkali-treated in a slightly wet state, and then a quaternary ammonium compound containing a glycidyl group is added and reacted to specify a dry cationization method. Although xanthan gum is contained as a polysaccharide, the function when cation-modified xanthan gum is blended in a cosmetic composition is not specified.

Patent Document 13 discloses a fiber treatment agent composed of an organopolysiloxane-containing polysaccharide compound composed of a main chain composed of a polysaccharide compound and a side chain composed of an organopolysiloxane chain, and is treated with a treatment such as cationization of xanthan gum as a polysaccharide derivative. Although it is specified that a derivative can be used, the structure is different from the cationized xanthan gum of the present invention.

Patent Document 14 contains a glycidyl trialkylammonium salt as a hydrophilizing agent in a xanthan gum derivative obtained by reacting a cross-linking agent with xanthan gum and then reacting with a hydrophilizing agent, and a small amount in the toiletries and cosmetics fields. It is clearly stated that it exhibits excellent thickening effect due to the addition of water, there is little change in viscosity due to temperature change, it is excellent in water solubility and transparency, but this is because it uses cross-linked xanthan gum. The structure is different from the cation-modified xanthan gum according to the invention.

  Patent Document 15 discloses a hair cosmetic such as a hair wash, a set agent, and a permanent agent containing at least one selected from an oxidizing agent, a reducing agent, a film-forming polymer, an oxidizing dye, and an acidic dye, and an oxyalkylenated xanthan gum. Although it is clearly stated that it is easy to apply to the hair and excellent in the feeling of use, it is not specified about the cation-modified xanthan gum.

  Patent Document 16 describes cosmetics containing siliconized polysaccharides. When this substance is added, biodegradability and biological safety are high, water resistance and oil resistance are excellent, cosmetic durability is good, and there is little secondary adhesion. However, the polysaccharide compound contains a cationized derivative of xanthan gum, but the structure is different from that of the cation-modified xanthan gum of the present invention.

A water-swellable polymer gel formed from an esterified carboxyl group-containing polysaccharide and a compound having two or more α-amino groups derived from natural amino acids has high water absorption and high gel strength and high safety to the human body. The xanthan gum is easily produced in an aqueous solvent and xanthan gum is specified as the carboxyl group-containing polysaccharide, but there is no specific description that the cation-modified xanthan gum is suitable for cosmetic use.

(Evaluation)
From the composition shown in the blank (F) of Table 2 as the shampoos of the formulations S1 to S7 and comparative products C1, C2 and C3 of the present invention prepared in the above-mentioned 4-a to 4-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.

From the composition shown in the blank (F) of Table 2 as the shampoos of the formulations S1 to S7 and comparative products C1, C2 and C3 of the present invention prepared in the above-mentioned 4-a to 4-f. About the shampoo which becomes, after washing hair with 10 testers, the softness of the hair after drying with a dryer was confirmed. The number of testers who felt that the finished hair quality was soft was evaluated according to the following criteria, and the results are shown in Table 3.
・ 8 or more testers who felt that their hair quality was soft ... ◎
・ 6-7 testers who felt that their hair quality was soft ... ○
・ 4-5 testers who felt that their hair quality was soft ... △
・ There are less than 4 testers who feel that their hair quality is soft ... ×

  From the results in Table 3, the shampoos S1 to S4 of the present invention containing the cation-modified xanthan gums of sample numbers 1, 2, 3, and 4 obtained by cation-modifying xanthan gum showed a large change in bending rigidity (B value) compared to the blank. Although not, the hysteresis width (2HB) is improved. Similar results were also found in Comparative Product C2 containing the cation-modified xanthan gum of Sample No. 6, which has a higher cation charge value than the range of the present invention, but the bending stiffness was increased, suggesting a sense of stiffness. On the other hand, the comparative product C1 containing the cation-modified xanthan gum of Sample No. 5 having a cation charge amount lower than the range of the present invention and the comparative product C3 containing the unmodified xanthan gum had almost the same results as the blank. This is because when unmodified xanthan gum and cation-modified xanthan gum having a cation charge value lower than the range of the present invention are washed out and used in the product, the adsorptive capacity based on ionicity cannot be obtained for the hair, and the xanthan gum is applied to the hair. It is considered that the effect was not obtained because of a small amount of adsorption. On the other hand, since the product of the present invention in which xanthan gum is cation-modified has an adsorption ability based on ionicity to hair, 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 was found that the cation-modified xanthan gum of the present invention exerts its effect sufficiently even when it is blended into a wash-out product such as shampoo and rinse.

  Further, the cation-modified xanthan gum of the present invention, cation-modified hydroxyethyl cellulose having an average added mole number of ethylene oxide of 1.8 and a nitrogen content of 1.8% by mass (Kachinal HC-100; manufactured by Toho Chemical Co., Ltd.), N- Hysteresis in systems used in combination with water-soluble polymers with conditioning effects such as methacryloyloxyethyl N, N-dimethylammonium-α-methylcarboxybetaine / alkyl methacrylate copolymer (Yukaformer SM; manufactured by Mitsubishi Chemical Corporation) There was no significant difference in width (2HB), and it was confirmed that not only the effect was not lost by the combined use, but also the bending rigidity was moderately improved and the hair was firm.

Example 5 Softness to hair (part 2)
(Evaluation)
Using the shampoos of the formulations S1 to S7 of the products of the present invention prepared in Example 4 and the shampoos of the comparative products C1, C2 and C3, the softness of the cation-modified xanthan gum of the present invention with respect to damaged hair was washed away and confirmed by the products. did. A hair strand similar to that used in Example 4 was added to a bleaching agent of 2 to 1 mixture (w / w) of 6% H2O2 and 3% aqueous ammonia (w / w) in a bath ratio of 1 to 100 (hair strand weight to bleaching agent). Solution weight), and immersed for 60 minutes at 40 ° C. After washing with warm water, it was dried with a dryer. Comparatively produced products C1 to C3 prepared according to the prescriptions S1 to S7, 4-e and 4-f of the products of the present invention prepared in the above-mentioned 4-a to 4-d were used for the damaged hair strands obtained by this bleaching treatment. Furthermore, 1.0 g of a shampoo having the composition shown in the blank (F) of Table 2 was used as a blank to wash 15 g of hair strands (total length: 180 mm). 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 4.

  When evaluated with damaged hair from the results in Table 4, when the shampoos S1 to S7 including the product of the present invention are compared with the blank, both the bending rigidity (B value) and the hysteresis width (2HB) are improved. Similar results are seen in comparative product C2 containing the cation-modified xanthan gum of Sample No. 6, which has a higher cation charge value than the range of the present invention. On the other hand, in the comparative product C1 containing the cation-modified xanthan gum of Sample No. 5 whose cation charge value is lower than the range of the present invention, the bending rigidity is considerably improved, but the hysteresis width is such that a superior difference from the blank can be confirmed. No improvement was obtained, and the comparative product C3 containing unmodified xanthan gum was almost the same as the comparative product C1. Furthermore, since the difference between the bending stiffness and the hysteresis width from the blank is larger than that in the case of the unbleached untreated healthy hair of Example 4, the usefulness of the product of the present invention on the damaged hair was confirmed. It was.

  Further, the cation-modified xanthan gum of the present invention, cation-modified hydroxyethyl cellulose having an average added mole number of ethylene oxide of 1.8 and a nitrogen content of 1.8% by mass (Kachinal HC-100; manufactured by Toho Chemical Co., Ltd.), N- Hysteresis in systems used in combination with water-soluble polymers with conditioning effects such as methacryloyloxyethyl N, N-dimethylammonium-α-methylcarboxybetaine / alkyl methacrylate copolymer (Yukaformer SM; manufactured by Mitsubishi Chemical Corporation) It was confirmed that the width (2HB) was not so large and not only the effect was not lost by the combined use, but also the bending rigidity was moderately improved and the hair was firm.

Example 6 Salt tolerance The salt tolerance of the cation-modified xanthan gum of the present invention (sample numbers 1, 2, 3, and 4 in Table 1) was confirmed by the following method. Salt was added to the rinse-off product (shampoo) formulation in Table 2 and the appearance was observed. For comparison, cation-modified guar gum obtained by cation modification of guar gum (composition ratio of mannose and galactose, 2 to 1), which is a galactomannan polysaccharide and having a different composition ratio of mannose and galactose, and locust bean gum (of mannose and galactose) Cation-modified locust bean gum obtained by cation-modifying the composition ratio (4: 1) (Sample Nos. 9 and 10 in Table 1) Further, as other cationic polymer, ethylene oxide average addition mole number 1.8, nitrogen content 1.8 A similar salt addition test was carried out for each of the mass% cation-modified hydroxyethyl cellulose (Kachinal HC-100; manufactured by Toho Chemical Co., Ltd.). The results are shown in Table 5.
Evaluation was made according to the following criteria.

  From the results shown in Table 5, the cation-modified xanthan gum of the present invention is a cation-modified guar gum and a cation-modified locust bean gum (sample numbers 7 and 8 in Table 1). When the shampoo formulation was assembled from cation-modified hydroxyethyl cellulose having a nitrogen content of 1.8% by mass, it was proved that the salt resistance was good. Therefore, when the cation-modified xanthan gum of the present invention is blended in a hair treatment composition or a skin cosmetic composition, it can be blended in a formulation containing a large amount of sodium chloride.

  Hereinafter, the conditioning effect and flexibility obtained by the cation-modified xanthan gum were further confirmed in each of the cosmetic compositions having different dosage forms.
