Description

【0001】
【発明の属する技術分野】
本発明は、ヘアリンス、ヘアコンディショナー、ヘアトリートメントクリーム、ヘアトリートメントムース、PPT(ポリペプタイド)トリートメント剤、ヘアクリーム、毛髪セット剤などの毛髪処理剤に関し、さらに詳しくは、毛髪への収着性が優れ、毛髪のセット力を向上させ、毛髪をなめらかにして毛髪の櫛通り性を改善し、毛髪に優れた艶、潤い感を付与し、かつ毛髪をしなやかな感触に仕上げることができる毛髪セット効果およびコンディショニング効果に優れた毛髪処理剤に関する。
【0002】
【従来の技術】
従来から、ヘアリンス、へアコンディショナー、ヘアトリートメント剤などの毛髪処理剤には、コンディショニング剤としてカチオン性界面活性剤、シリコーン、油性物質などが配合されてきた。
【0003】
しかしながら、上記の工夫では、毛髪の表面物性が改善されるだけであって、パーマネントウェーブ処理や染毛処理などの強い化学的処理、毎日の洗髪による毛髪のタンパク成分の溶出による毛髪の損傷、ヘアドライヤーや過剰なブラッシングなどの物理的損傷などによって毛髪の保湿性が低下したり、毛髪がぱさつくようになったときに、それらを解消することができないという問題があった。
【0004】
そのため、毛髪処理剤に、コラーゲン、ケラチン、シルク、大豆、小麦などの蛋白質を加水分解した加水分解ペプチドやそれらの誘導体を配合し、損傷により溶出したタンパクを補ったり、毛髪表面に被膜を形成させて毛髪に艶や良好な櫛通り性を付与したり、毛髪に保湿感を付与するすることが行われている。これは、それらの加水分解ペプチドやその誘導体が天然蛋白質由来であって、毛髪への親和性が高く、かつ毛髪に対する刺激が少なく、安全性が高いという理由によるものである。
【0005】
上記のタンパク源の中でも、ケラチンはシスチン含有量が多く、加水分解ケラチンやその誘導体はジスルフィド結合を有していて毛髪のジスルフィド結合と酸化還元反応により結合しやすく、そのため毛髪への収着性が優れ、毛髪の損傷防止作用や損傷毛の回復作用が優れ、また、毛髪のセット力を向上させる効果を有することから、各種の毛髪処理剤に用いられている。
【0006】
しかしながら、化粧品原料として用いられるケラチンは、主として羊毛から得られているものであるため、特有の動物臭があり、その効果を充分に発現させる量を化粧品に配合することが困難であった。また、牛伝達性海綿状脳症の発生から、消費者動向は有蹄類動物由来原料を忌避する傾向にあり、羊毛由来の加水分解ケラチンに代わる蛋白質加水分解物を配合した毛髪処理剤が求められていた。
【0007】
化粧品原料として用いられるタンパク源の中で、シスチン含量が高いものは、上記のケラチン以外にはあまり見当たらず、唯一卵殻膜がその構成アミノ酸中10モル%近くと高いシスチン含有量を有している。
【0008】
卵殻膜は、従来より創傷や火傷の処置に使われていたためか、卵殻膜加水分解物や卵殻膜抽出タンパクを皮膚老化防止、抗炎症、肌荒れ防止効果を目的に、主として皮膚化粧料に使用されているが、育毛・養毛剤に配合したり(特開昭48−40944号公報)、パーマネントウェーブ効果の向上を目的に毛髪処理剤に配合する(特開2000−128744号公報)など毛髪化粧料への利用も提案されている。
【0009】
しかしながら、これらの毛髪化粧料に使用されている卵殻膜は、卵殻膜の加水分解物あるいは卵殻膜の粉末で、毛髪に対しての収着力が羊毛由来の加水分解ケラチンやその誘導体に比べるとやや劣り、従って、毛髪への艶、潤い感、はり、セット力などの付与効果の点で充分に満足できるものではなかった。また、化粧品基材の研究に携わる者にとっては、卵殻膜の有するシスチン含有量が多いという特性を損なうことなく、さらに有用な特性を付加し、それらを化粧品に配合することによって、より高品質なものを得たいという要望もある。
【0010】
【発明が解決しようとする課題】
従って本発明は、上記のような従来技術における問題点を解決し、毛髪に優れた艶、潤い感、はりを付与し、毛髪の櫛通り性を改善し、毛髪のセット力を向上させ、かつ毛髪をなめらかな感触に仕上げることができ、しかも、羊毛由来の加水分解ケラチン誘導体のような独特の動物臭がない毛髪処理剤を提供することを目的とする。
【0011】
【課題を解決するための手段】
本発明者らは、上記課題を解決するため研究を重ねた結果、下記一般式(I)で示される卵殻膜加水分解ペプチドのN−第4級アンモニウム誘導体及び/又は下記一般式(II)で示される卵殻膜加水分解ペプチドのN−シリル化誘導体が、毛髪への収着性が優れ、毛髪に優れた艶、潤い感、はりを付与し、毛髪の櫛通り性を改善し、毛髪のセット力を向上させ、毛髪をなめらかな感触に仕上げることができることを見出し、本発明を完成するにいたった。

【0017】
【発明の実施の形態】
本発明の毛髪処理剤に含有させる前記一般式(I)で示される卵殻膜加水分解ペプチドのN−第4級アンモニウム誘導体及び前記一般式(II)で示される卵殻膜加水分解ペプチドのN−シリル化誘導体のペプチド部分の原料となる卵殻膜加水分解ペプチドは、鶏、うずら、あひる、七面鳥などの鳥卵から得られた卵殻膜を、酸、アルカリ、酵素、酸化剤や還元剤などを用いて、一般に蛋白質から加水分解ペプチドを得る公知の方法で製造することができる。
【0018】
卵殻膜加水分解物の製造法としては、例えば、特公昭54−023975号公報、特開平1−275512号公報、特開平4−148649号公報、特開平5−97897号公報等に開示されいて、また、可溶性卵殻膜は市販もされているので〔キューピー(株)製EMプロテイン(商品名)〕、一般式(I)で示される卵殻膜加水分解ペプチドのN−第4級アンモニウム誘導体や一般式(II)で示される卵殻膜加水分解ペプチドのN−シリル化誘導体のペプチド部分に、これら公報記載の方法で得られた卵殻膜加水分解ペプチドや、市販品の可溶性卵殻膜を利用することもできる。
【0019】
ただ、本発明の毛髪処理剤に使用する一般式(I)で示される卵殻膜加水分解ペプチドのN−第4級アンモニウム誘導体や一般式(II)で示される卵殻膜加水分解ペプチドのN−シリル化誘導体のペプチド部分は、以下にその理由を記すように、数平均分子量が約200〜約5,000のものが好ましく、これら公報開示の方法で分解したものや市販品の可溶性卵殻膜を利用するとペプチドの数平均分子量がやや大きいため、さらに、酸、アルカリ、酵素などを用いて分解して、数平均分子量が約200〜約5,000になるようにするのが好ましい。
【0020】
本発明の毛髪処理剤に使用する一般式(I)で示される卵殻膜加水分解ペプチドのN−第4級アンモニウム誘導体及び一般式(II)で示される卵殻膜加水分解ペプチドのN−シリル化誘導体のペプチド部分の数平均分子量は、約200〜約5,000のものが好ましく、約250〜約3,000になるようにするのがより好ましい。これは、卵殻膜加水分解ペプチドの誘導体のペプチド部分の数平均分子量が上記範囲より小さい場合は、毛髪への収着性が低くなる上に、加水分解ペプチドの有する毛髪をなめらかにして櫛通り性を改善し、毛髪に優れた艶、潤い、なめらかさを付与してしなやかな感触に仕上げる効果や毛髪のセット力を向上させる効果などが充分に発揮することができなくなるおそれがあり、卵殻膜加水分解ペプチドの誘導体のペプチド部分の数平均分子量が上記範囲より大きくなると、毛髪がゴワついたり、高湿度下では毛髪がべたついたりするおそれがあるからである。
【0021】
本発明の毛髪処理剤に用いる前記一般式(I)で示される卵殻膜加水分解ペプチドのN−第4級アンモニウム誘導体は、例えば、アルカリ条件下で卵殻膜加水分解ペプチドと第4級アンモニウム化合物とを反応させることによって製造できる。
【0022】

【0023】
そして、一般式(I)で示される卵殻膜加水分解ペプチドのN−第4級アンモニウム誘導体の具体例としては、例えば、卵殻膜加水分解ペプチドのトリメチルアンモニオ−2−ヒドロキシプロピル誘導体、トリエチルアンモニオ−2−ヒドロキシプロピル誘導体、ラウリルジメチルアンモニオ−2−ヒドロキシプロピル誘導体、ヤシ油アルキルジメチルアンモニオ−2−ヒドロキシプロピル誘導体、ステアリルジメチルアンモニオ−2−ヒドロキシプロピル誘導体、ベンジルジメチルアンモニオ−2−ヒドロキシプロピル誘導体などが挙げられる。
【0024】
また、前記一般式(II)で示される卵殻膜加水分解ペプチドのN−シリル化誘導体は、例えば、酸性あるいはアルカリ条件下で卵殻膜加水分解ペプチドとシリル化剤と称される物質とを反応させて得られるが、特開平8−59424号公報、特開平8−607608号公報、特開平7−228505号公報などに記載の方法を利用することによって製造することができる。
【0025】
上記シリル化剤の具体例としては、例えば、3−グリシジルオキシプロピルメチルジメトキシシラン、3−グリシジルオキシプロピルメチルジエトキシシラン、3−グリシジルオキシプロピルトリメトキシシラン、3−クロロプロピルメチルジクロロシラン、3−クロロプロピルメチルジメトキシシラン、3−クロロプロピルメチルジエトキシシラン、3−クロロプロピルトリメトキシシランなどが挙げられる。
【0026】
そして、一般式(II)で示される卵殻膜加水分解ペプチドのN−シリル化誘導体の具体例としては、例えば、卵殻膜加水分解ペプチドの2−ヒドロキシ−3−(3−トリヒドロキシシリルプロポキシ)プロピル誘導体、2−ヒドロキシ−3−(3−ジヒドロキシメチルシリルプロポキシ)プロピル誘導体、2−ヒドロキシ−3−(3−ジメチルヒドロキシシリルプロポキシ)プロピル誘導体、3−トリヒドロキシシリルプロピル誘導体、3−ジヒドロキシメチルシリルプロピル誘導体、3−ジメチルヒドロキシシリルプロピル誘導体などが挙げられる。
【0027】
本発明の毛髪処理剤は、一般式(I)で示される卵殻膜加水分解ペプチドのN−第4級アンモニウム誘導体及び/又は一般式(II)で示される卵殻膜加水分解ペプチドのN−シリル化誘導体を各種の毛髪処理剤に含有させることによって構成されるが、対象となる毛髪処理剤としては、例えば、ヘアリンス、ヘアコンディショナー、ヘアトリートメントクリーム、ヘアトリートメントムース、PPT(ポリペプタイド)トリートメント剤、ヘアクリーム、毛髪セット剤などが挙げられる。
【0028】
そして、一般式(I)で示される卵殻膜加水分解ペプチドのN−第4級アンモニウム誘導体及び/又は一般式(II)で示される卵殻膜加水分解ペプチドのN−シリル化誘導体の毛髪処理剤中の含有量(毛髪処理剤中への配合量)としては、毛髪処理剤の種類によって含有量は多少変化するが、毛髪処理剤中0.05〜30質量%が好ましく、0.5〜15質量%にするのがより好ましい。
【0029】
これは、一般式(I)で示される卵殻膜加水分解ペプチドのN−第4級アンモニウム誘導体及び/又は一般式(II)で示される卵殻膜加水分解ペプチドのN−シリル化誘導体の毛髪処理剤中の含有量が上記範囲より少ない場合は、毛髪をなめらかにして毛髪の櫛通り性を改善し、毛髪に優れた艶、潤い感を付与し、かつ毛髪をしなやかな感触に仕上げたり、毛髪のセット力を向上させる効果が充分に発揮されないおそれがあり、また逆に、一般式(I)で示される卵殻膜加水分解ペプチドのN−第4級アンモニウム誘導体及び/又は一般式(II)で示される卵殻膜加水分解ペプチドのN−シリル化誘導体の毛髪処理剤中の含有量が上記範囲より多くなると、毛髪にゴワツキ感やべたつき感を与えるおそれがある。ただ、パーマネントウェーブ処理や染毛処理などの中間処理で使用されるPPTトリートメント剤では、含有量が20質量%を超えるものもある。
【0030】
本発明の毛髪処理剤は、一般式(I)で示される卵殻膜加水分解ペプチドのN−第4級アンモニウム誘導体及び/又は一般式(II)で示される卵殻膜加水分解ペプチドのN−シリル化誘導体を各種の毛髪処理剤に含有させることによって構成されるが、2種以上含有させる場合は、ペプチド部分の数平均分子量が同じ卵殻膜加水分解ペプチドのN−第4級アンモニウム誘導体とN−シリル化誘導体を含有させてもよく、同種でペプチド部分の数平均分子量が異なるものを2種以上用いてもよいし、ペプチド部分の数平均分子量が異なるN−第4級アンモニウム誘導体とN−シリル化誘導体を含有させてもよい。
【0031】
また、本発明の毛髪処理剤に一般式(I)で示される卵殻膜加水分解ペプチドのN−第4級アンモニウム誘導体及び/又は上記一般式(II)で示される卵殻膜加水分解ペプチドのN−シリル化誘導体と併用して配合できる成分としては、例えば、アニオン性界面活性剤、ノニオン性界面活性剤、両性界面活性剤、カチオン性界面活性剤、カチオン性ポリマー、両性ポリマー、アニオン性ポリマー、増粘剤、動植物抽出物、動植物および微生物由来のタンパク質の加水分解ペプチドやそのペプチドエステル誘導体、卵殻膜以外の動植物および微生物由来のタンパク質の加水分解ペプチドのN−第4級アンモニウム誘導体やN−シリル化誘導体、湿潤剤、低級アルコール類、アミノ酸類、動植物油、炭化水素類、エステル油、高級アルコール類、シリコーン類、天然多糖類、などが挙げられるが、これら以外にも本発明の毛髪処理剤の特性を損なわない範囲で、適宜他の成分を添加することができる。

【実施例】
つぎに、実施例を挙げて本発明をより具体的に説明する。ただし、本発明はそれらの実施例のみに限定されるものではない。なお、以下の実施例や比較例中における各成分の配合量はいずれも質量部によるものであり、配合量が固形分量でないものについては、成分名の後に括弧書きで固形分濃度を示す。
【0034】
実施例1および比較例1〜2
表1に示す組成の3種類のヘアリンスを調製し、それぞれのヘアリンスをシャンプーで洗浄した毛髪に使用して、毛髪の艶、潤い感、なめらかさ、櫛通り性および処理後の毛髪の残臭の少なさを評価した。なお、表1中の各成分の配合量はいずれも重量部によるものであり、配合量が固形分量でないものについては、成分名のあとに括弧書きで固形分濃度を示している。これらは、以降の組成を示す表3、表5、表7などにおいても同様である。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a hair treatment agent such as a hair rinse, a hair conditioner, a hair treatment cream, a hair treatment mousse, a PPT (polypeptide) treatment agent, a hair cream, and a hair setting agent, and more particularly, has excellent sorption property to hair. A hair setting effect that improves the hair setting power, smoothes the hair, improves the combability of the hair, gives the hair an excellent luster, a moist feeling, and can finish the hair with a supple feel. The present invention relates to a hair treatment agent having an excellent conditioning effect.
[0002]
[Prior art]
BACKGROUND ART Conventionally, hair treatment agents such as hair rinses, hair conditioners, and hair treatment agents have been formulated with a cationic surfactant, silicone, an oily substance, or the like as a conditioning agent.
[0003]
However, the above measures only improve the surface properties of the hair, and include strong chemical treatments such as permanent wave treatment and hair dyeing treatment, damage to the hair due to elution of protein components of the hair due to daily hair washing, and There has been a problem that when the moisturizing property of the hair is reduced due to physical damage such as a dryer or excessive brushing, or when the hair becomes loose, these cannot be eliminated.
[0004]
Therefore, the hair treatment agent is mixed with hydrolyzed peptides or their derivatives, which hydrolyze proteins such as collagen, keratin, silk, soybeans, and wheat, to supplement the proteins eluted due to damage or to form a film on the hair surface. In order to impart gloss and good combability to hair, and to impart a moisturizing feeling to hair. This is because these hydrolyzed peptides and derivatives thereof are derived from natural proteins, have high affinity for hair, have little irritation to hair, and have high safety.
[0005]
Among the above protein sources, keratin has a high cystine content, and hydrolyzed keratin and its derivatives have a disulfide bond and are easily bonded to the hair by a disulfide bond and a redox reaction, so that sorption to hair is improved. It is used in various hair treatment agents because it is excellent, has an effect of preventing damage to hair and an effect of recovering damaged hair, and has an effect of improving hair setting power.
[0006]
However, since keratin used as a cosmetic raw material is mainly obtained from wool, it has a peculiar animal odor, and it has been difficult to mix the keratin with an amount sufficient to exert its effect in cosmetics. In addition, due to the occurrence of bovine transmissible spongiform encephalopathy, consumer trends tend to avoid raw materials derived from ungulates, and hair treatment agents containing protein hydrolyzate instead of hydrolyzed keratin derived from wool are required. I was
[0007]
Among the protein sources used as cosmetic raw materials, those with a high cystine content are rarely found other than the above keratin, and only the eggshell membrane has a high cystine content of nearly 10 mol% in its constituent amino acids. .
[0008]
Eggshell membranes have been used in the treatment of wounds and burns.Hydrolyzed eggshell membranes and proteins extracted from eggshell membranes are mainly used in skin cosmetics for the purpose of preventing skin aging, anti-inflammation and rough skin. However, it is used in hair cosmetics such as a hair restorer / hair restorer (JP-A-48-40944) and a hair treatment agent for the purpose of improving the permanent wave effect (JP-A-2000-128744). The use of is also proposed.
[0009]
However, eggshell membranes used in these hair cosmetics are eggshell membrane hydrolysates or eggshell membrane powders, and their sorbing power on hair is slightly higher than that of hydrolyzed keratin or its derivatives derived from wool. Inferior, therefore, it was not sufficiently satisfactory in terms of imparting effects such as gloss, moist feeling, glue, setting power and the like to hair. In addition, for those engaged in research on cosmetic base materials, more useful properties are added without compromising the high cystine content of eggshell membranes, and by incorporating them into cosmetics, higher quality is achieved. There is also a desire to get something.
[0010]
[Problems to be solved by the invention]
Accordingly, the present invention solves the problems in the prior art as described above, imparts excellent gloss, moist feeling, and beam to hair, improves combability of hair, improves hair setting power, and An object of the present invention is to provide a hair treatment agent capable of finishing hair with a smooth feel and having no peculiar animal odor such as a hydrolyzed keratin derivative derived from wool.
[0011]

The treatment of the hair with the hair setting agent was performed as follows. That is, hair of 18 cm in length was previously washed with a 2% aqueous solution of sodium polyoxyethylene (3) lauryl ether sulfate, rinsed with water and air-dried at room temperature to prepare three hair bundles of 20 hairs. Each of them was wound around a rod. Use a glass tube with a diameter of 10 mm and a length of 80 mm, which has been marked on the rod in advance every 10 mm (the opposite side is also marked by 5 mm). The bundle was wound, both ends were fixed with rubber bands, and the hair setting agent of Example 3 and Comparative Examples 5 to 6 was applied to the hair bundle wound around the rod in an amount of 2 ml each and dried in a hot air dryer at 90 ° C. . After drying, the hair was allowed to stand in a desiccator with the rod suspended horizontally for 12 hours. After 12 hours, the hair bundle was removed from the rod, and the wavelength and wave number of the wave were measured. Then, a hair weight of 3 g was attached to the tip of the hair, and the hair bundle was set in a vertical state and left in a desiccator for 24 hours. Then, the weight was removed from the hair bundle, the hair bundle was set vertically and left in the desiccator for 12 hours. The wavelength and wave number of the wave were measured.
[0056]
As shown in Fig. 1, the measurement of the wavelength and wave number, except for the waves at both ends, measures the distance from the top of the second wave from one end to the top of the second wave from the other end. And the distance from the top of the left and right waves to the top is L1  , L2  And L1  And L2  The number of waves between1  , N2  And the average wavelength (L) was determined by the following equation.
[0057]
Figure 2004175699
[0058]
Since the wavelength (diameter) of the rod itself is 10 mm, the wave efficiency is obtained by the following equation.
[0059]
