従来、毛髪、皮膚用洗浄剤の基本的な機能は毛髪及び身体表面の汚れを取り去り、肌や髪の状態を清潔にすることであった。ところが、近年、シャワーの普及、入浴頻度や洗髪頻度の上昇、ヘアカラー、ヘアダイの使用機会の増加など、ヘアケア、スキンケアを取り巻く環境の変化に伴い、これらヘアケア、スキンケア製品に対して、単に汚れを取り除くだけでなく、使用時及び使用後の感触、仕上がり感の良さ、マイルド性、コンディショニング効果などが要求されるようになってきた。そのうち、毛髪、皮膚を保護し、その状態を整え、感触をよくすることを目的として、カチオン性高分子、カチオン性界面活性剤、シリコーン誘導体などのコンディショニング剤が広く用いられており、特にカチオン性高分子と界面活性剤による複合塩は、毛髪、皮膚を保護し、その状態を整え、感触をよくすることに優れていることから、従来、カチオン性高分子としてはコンディショニング効果の得られやすい、水溶液濃度が４質量％の時の水溶液粘度が２，０００ｍＰａ・ｓ以上の水溶液粘度の高い、カチオン変性セルロース誘導体が主に用いられてきた。しかしながら、このような水溶液粘度の高いカチオン変性セルロース誘導体と界面活性剤による複合塩は、コンディショニング効果は得られやすい反面、繰り返し使用することで、形成した複合塩が毛髪などに蓄積（ビルドアップ）し、洗髪時の指通りの悪化や、乾いた髪のごわつき感など悪影響を及ぼす。特に近年、洗髪回数の増加、ファッションの多様化によるヘアカラー、ヘアダイを使用する機会が増加し、これに伴う毛髪の損傷により、複合塩の毛髪表面への蓄積は増加の傾向にあり、感触が問題となっている。 Conventionally, the basic function of hair and skin cleansing agents has been to remove dirt on the hair and body surface and to clean the skin and hair. However, in recent years, due to changes in the environment surrounding hair care and skin care, such as the spread of showers, increased frequency of bathing and washing, increased use of hair colors and hair dyes, these hair care and skin care products are simply soiled. In addition to removal, a feeling during use and after use, a good finish, a mildness, and a conditioning effect have been required. Of these, conditioning agents such as cationic polymers, cationic surfactants, and silicone derivatives are widely used for the purpose of protecting hair, skin, preparing the condition, and improving touch, especially cationic compounds. A complex salt composed of a polymer and a surfactant is excellent in protecting hair and skin, preparing its state, and improving touch, so that conventionally, a conditioning effect is easily obtained as a cationic polymer. A cation-modified cellulose derivative having a high aqueous solution viscosity of 2,000 mPa · s or higher when the aqueous solution concentration is 4% by mass has been mainly used. However, such a complex salt made of a cation-modified cellulose derivative having a high aqueous solution viscosity and a surfactant is easy to obtain a conditioning effect, but the complex salt formed (builds up) accumulates in hair etc. by repeated use. It also has adverse effects such as worsening of fingering during hair washing and stiffness of dry hair. In particular, in recent years, the number of shampooing has increased, the chances of using hair colors and hair dyes due to diversification of fashion have increased, and the resulting damage to the hair has led to an increase in the accumulation of complex salts on the hair surface. It is a problem.
また、カチオン変性セルロース誘導体は、皮膚への親和性が良好な点から塗布時の使用感、保湿効果等の多くの目的で配合されている。しかし、これらのカチオン変性セルロース誘導体を用いた場合、負に帯電している皮膚への吸着が著しく、コンディショニング効果は得られるが、ぬるつき等の残余感また、繰り返し使用した場合の蓄積等の問題を有している。さらに、水溶液粘度の高いカチオン変性セルロース誘導体は、カチオン電荷量によっては、複合塩の凝集など剤型の安定性に問題が生じる場合もあり、これら諸問題を解決できる化粧料組成物が望まれていた。 In addition, the cation-modified cellulose derivative is blended for many purposes such as a feeling of use at the time of application and a moisturizing effect because of its good affinity for the skin. However, when these cation-modified cellulose derivatives are used, the adsorption to the negatively charged skin is remarkable and the conditioning effect can be obtained, but there is a problem of residual feeling such as sliminess and accumulation when repeatedly used. have. Furthermore, cation-modified cellulose derivatives with high aqueous solution viscosity may cause problems in the stability of the dosage form, such as aggregation of complex salts, depending on the amount of cationic charge, and a cosmetic composition that can solve these problems is desired. It was.
かかる実情において、本発明者らは従来のカチオン変性セルロース誘導体を含む化粧料組成物を繰り返し使用することでの蓄積による使用感の悪化、更に、カチオン変性セルロース誘導体と界面活性剤の複合塩の凝集性を改善することによる剤型の安定化及び感触の改善について鋭意検討した結果、ヒドロキシエチルセルロースに、特定量の第4級窒素含有基を導入し、かつカチオン電荷量を特定範囲に調節した、特定の水溶液粘度を有するカチオン変性セルロースを含む化粧料組成物が、剤型の安定性に優れ、繰り返し使用した場合の使用感が良好であることを見出し、本発明品を完成するに至った。 Under such circumstances, the present inventors have deteriorated the feeling of use due to repeated use of a cosmetic composition containing a conventional cation-modified cellulose derivative, and further agglomerated a complex salt of a cation-modified cellulose derivative and a surfactant. As a result of diligent investigations on stabilization of the dosage form and improvement of feel by improving the properties, a specific amount of quaternary nitrogen-containing groups was introduced into hydroxyethyl cellulose, and the cationic charge amount was adjusted to a specific range The cosmetic composition containing cation-modified cellulose having an aqueous solution viscosity was found to have excellent dosage form stability and good usability when used repeatedly, and the present invention product was completed.
従って本発明は、各種毛髪処理用組成物、皮膚化粧料組成物、その他メイクアップ剤等の化粧料組成物への使用に適する、ヒドロキシエチルセルロースに含まれる水酸基の一部が、下記化学式(1)で表される第４級窒素含有基で置換された、水溶液濃度が４質量％のときの水溶液粘度が５０〜５００ｍＰａ・ｓであるカチオン変性セルロースであって、該第４級窒素含有基由来のカチオン電荷量が０．１〜３．０meq/gである低粘度カチオン変性セルロース(以下、低粘度カチオン変性セルロースとも記す)を含む化粧料組成物に関する。
本発明の低粘度カチオン変性セルロースは、シャンプー・リンスなど毛髪処理用組成物に配合した場合、使用時には毛髪に対し、従来のコンディショニング剤として用いられる、カチオン性高分子と同等以上のコンディショニング効果を与えつつ、繰り返し使用した場合、毛髪表面への蓄積が少なく、良好な感触が得られる。さらに、皮膚化粧料組成物に配合した場合、ぬるつき等の残余感及び、繰り返し使用した場合の蓄積等の問題を解決し、良好な仕上がり感を与え、複合塩の凝集など剤型の安定性への影響も生じない。従って、従来品よりもより使い心地の優れた化粧料組成物を提供することが出来る。 The low-viscosity cation-modified cellulose of the present invention, when blended in a hair treatment composition such as shampoo and rinse, gives the hair a conditioning effect equivalent to or better than that of a cationic polymer used as a conventional conditioning agent when used. On the other hand, when used repeatedly, there is little accumulation on the hair surface and a good feel can be obtained. Furthermore, when formulated into a skin cosmetic composition, it solves problems such as residual feeling such as luster and accumulation when repeatedly used, gives a good finish, and stability of the dosage form such as aggregation of complex salts There will be no impact on Therefore, it is possible to provide a cosmetic composition that is more comfortable to use than conventional products.

[Production of low viscosity cation-modified cellulose]
Example 1
After adding 10.0 g of 48 mass% aqueous sodium hydroxide solution to 900 mL of 90 volume% isopropanol aqueous solution, 240 g of hydroxyethyl cellulose (AL-15: manufactured by Sumitomo Seika Co., Ltd.) having a 4% aqueous solution viscosity of 180 mPa · s was added. Gradually added and dispersed. Next, 82.0 g of an 80% by mass glycidyltrimethylammonium chloride (hereinafter also referred to as GTA) aqueous solution was added, and the mixture was heated and reacted at 50 ° C. for 3 hours. After completion of the reaction, 11.8 g of 35% hydrochloric acid was diluted with 1500 mL of 90 volume% isopropanol aqueous solution and used for neutralization. After neutralizing at room temperature for 1 hour, the reaction solution was poured into 1800 mL of acetone to precipitate the reaction product, which was filtered off. The resulting precipitate was washed with an aqueous acetone solution, and then the reaction product was dried under reduced pressure. The low-viscosity cation-modified cellulose thus obtained had a cation charge of 1.30 meq / g, an aqueous solution concentration of 4% by mass, and an aqueous solution viscosity of 25 ° C. using a Brookfield viscometer. It was 180 mPa · s when measured at 2, 30 rpm. The results are shown in Table 1 (Sample No. 1 in Table 1). In addition, when the molecular weight of the hydroxyethyl cellulose and the low-viscosity cation-modified cellulose of the present invention was determined by GPC molecular weight measurement, the weight average molecular weights were 50,000 each.
同様に添加するＧＴＡの量を変えることでカチオン電荷量の異なる低粘度カチオン変性セルロースを合成した。この結果を表１中に示した（表１中、試料番号２、３）。さらに、ＡＬ−１５の代わりに粘度の異なるヒドロキシエチルセルロースを使用し、実施例１と同様の方法で水溶液粘度のことなる低粘度カチオン変性セルロースを合成した。この結果を表１中に示した（表１中、試料番号４、５）。 Similarly, low-viscosity cation-modified cellulose having a different cation charge amount was synthesized by changing the amount of GTA to be added. The results are shown in Table 1 (Sample numbers 2 and 3 in Table 1). Further, hydroxyethyl cellulose having a different viscosity was used in place of AL-15, and a low-viscosity cation-modified cellulose having a different aqueous solution viscosity was synthesized in the same manner as in Example 1. The results are shown in Table 1 (in Table 1, sample numbers 4 and 5).
実施例２
実施例１で用いた４８質量％の水酸化ナトリウム水溶液の量を５７．６ｇとし、ＧＴＡの代わりに、３−ハロゲノ−２−ヒドロキシプロピルジメチルモノラウリルアンモニウムクロライド１７５．２ｇを加え同様に合成した。このようにして得られた低粘度カチオン変性セルロースのカチオン電荷量は０.７９ｍｅｑ／ｇであった。この結果を表１中に示した（表１中、試料番号６）。
Example 2
The amount of the 48 mass% sodium hydroxide aqueous solution used in Example 1 was 57.6 g, and instead of GTA, 175.2 g of 3-halogeno-2-hydroxypropyldimethylmonolauryl ammonium chloride was added and synthesized in the same manner. The cation charge amount of the low viscosity cation-modified cellulose thus obtained was 0.79 meq / g. The results are shown in Table 1 (Sample No. 6 in Table 1).
