Description

毛髪処理剤Hair treatment agent
　本発明は、毛髪処理剤に関する。 The present invention relates to a hair treatment agent.
　近年、毛髪化粧料には、毛髪に滑らかさやまとまりを付与できるコンディショニング効果がより期待されるようになってきている。カチオン性ポリマーや脂肪酸の配合によって毛髪に滑らかさやまとまり等を付与する技術は既に報告されている。しかしそれらの効果は持続性に乏しく、翌日の洗髪までには、滑らかさやまとまりが消失してしまうものであった。また、コンディショニング効果の持続を高めるためカチオン性ポリマーの配合量を増加させると、すすぎ時の毛髪にべたつき感が生じ、乾燥後に毛髪が揃いにくくなり、重い感触が残るという問題があった。 In recent years, hair cosmetics are increasingly expected to have a conditioning effect that can impart smoothness and unity to the hair. A technique for imparting smoothness, unity, etc. to hair by blending a cationic polymer or a fatty acid has already been reported. However, these effects were poor in sustainability, and smoothness and unity disappeared by the next day's hair washing. Moreover, when the blending amount of the cationic polymer is increased in order to increase the duration of the conditioning effect, there is a problem that the hair feels sticky during rinsing, the hair becomes difficult to align after drying, and a heavy feel remains.
　これに対し特許文献１では一つ又は複数のカチオン性ポリマーとカチオン性界面活性剤を組み合わせることで、清潔で、輝きがあり、滑らかで、柔軟な毛髪をもたらし、梳かすことが容易になり、その良好な化粧料の特性は、複数回シャンプーを行った後でさえ、長期間持続される化粧料組成物が開示されている。また、特許文献２には、特定のカチオン性ポリマーと特定の分岐脂肪酸とを組み合わせることで、乾燥後の滑らかさやまとまりといったコンディショニング効果を持続させつつも、毛髪を揃いやすくし、更にひんやり感を付与して、心地よい感触が翌日の洗髪まで持続的に得られることが開示されている。また、特許文献３には、特定のカチオン性ポリマーと特定の混合脂肪酸との間で水不溶性の複合体を形成させ、更にシリコーン類とを組み合わせることで、処理直後から次の洗髪時まで持続する滑らかさとまとまりが得られる、洗い流すタイプの毛髪化粧料組成物が開示されている。 On the other hand, in Patent Document 1, combining one or a plurality of cationic polymers and a cationic surfactant, clean, shiny, smooth and soft hair is brought about, and it becomes easy to comb. Its good cosmetic properties have been disclosed for long-lasting cosmetic compositions even after multiple shampooing. In addition, Patent Document 2 combines a specific cationic polymer and a specific branched fatty acid to keep the conditioning effect such as smoothness and unity after drying, making the hair easier to align and providing a more chilly feeling. Thus, it is disclosed that a pleasant touch can be continuously obtained until the next day's hair washing. Further, in Patent Document 3, a water-insoluble complex is formed between a specific cationic polymer and a specific mixed fatty acid, and further combined with silicones, it lasts from immediately after treatment to the next shampooing time. A rinse-off type hair cosmetic composition that provides smoothness and unity is disclosed.

発明の詳細な説明Detailed Description of the Invention
　寝ぐせは、就寝時に寝具等から頭髪に加わる外力によって毛髪が身だしなみ上望ましくない形状に形付けられる現象であって、多くの人が日常生活で感じる煩わしい現象である。寝ぐせを直す際には、毛髪を水や整髪料で濡らしたり、加湿等をしたりすることにより、毛髪内部に存在する水素結合を一旦切断した後に、ドライヤーやヘアアイロン等で乾燥させながら、より好ましい形状で水素結合を再形成する、という操作が必要になる。この操作は概ね煩雑であることに加えて多くの手間と時間がかかるため、多忙な現代人にとっては、寝ぐせがつきにくくなり、かつ良好な毛髪感触が次の洗髪まで続く毛髪処理剤が求められていた。 Sleeping is a phenomenon in which hair is shaped into an undesired shape due to external force applied to the hair from bedclothes at bedtime, and is an annoying phenomenon that many people feel in daily life. When we lie down, wet the hair with water or a hair styling agent, or humidify it to cut hydrogen bonds existing inside the hair, then dry it with a dryer or hair iron, The operation of reforming hydrogen bonds in a more preferable shape is necessary. In addition to being cumbersome, this operation takes a lot of time and effort. For busy modern people, it is difficult to fall asleep and a hair treatment agent that maintains a good hair feel until the next shampoo is required. It was done.
　しかしながら、特許文献１～３はコンディショニング効果やその持続については開示しているが、毛髪の寝ぐせがつきにくくなる効果については示唆されておらず、また、その効果も不十分であった。 However, Patent Documents 1 to 3 disclose the conditioning effect and its duration, but do not suggest the effect of making it difficult for the hair to fall asleep, and the effect is insufficient.
　したがって、本発明は、毛髪を寝ぐせがつきにくくさせることに加えて、すすぎ時のベタつきを抑制するとともに毛髪に滑らかさを付与し、かつ毛髪のまとまりや滑らかさを次の洗髪時まで持続させることができ、更に耐シャンプー性に優れる毛髪処理剤に関する。 Therefore, in addition to making the hair less likely to fall asleep, the present invention suppresses stickiness during rinsing, imparts smoothness to the hair, and maintains the unity and smoothness of the hair until the next shampoo. Further, the present invention relates to a hair treatment agent having excellent shampoo resistance.
　本発明者らは、高カチオン密度のカチオン性ポリマー、低カチオン密度のカチオン性ポリマー、及び脂肪酸又はその塩を組み合わせてなる毛髪処理剤とすることによって、寝ぐせをつきにくくさせる効果、すすぎ時のベタつきを抑制する効果、毛髪に滑らかさを付与する効果、毛髪のまとまりや滑らかさを次の洗髪時まで持続させる効果、及び高い耐シャンプー効果が達成されること、更にはこの毛髪処理剤による処理に続き、カチオン性界面活性剤と高級アルコールを含有する第二の毛髪処理剤によって処理することにより、更に上記効果が向上することを見いだした。 The present inventors have a hair treatment agent comprising a combination of a cationic polymer having a high cation density, a cationic polymer having a low cation density, and a fatty acid or a salt thereof, thereby making it difficult to fall asleep, The effect of suppressing stickiness, the effect of imparting smoothness to the hair, the effect of maintaining the unity and smoothness of the hair until the next shampooing, and the high shampoo resistance are achieved, and further, the treatment with this hair treatment agent Subsequently, it was found that the above effect was further improved by treatment with a second hair treatment agent containing a cationic surfactant and a higher alcohol.
●毛髪処理剤
〔成分(A)：電荷密度3.0meq/g以上24meq/g以下のカチオン性ポリマー〕
　成分(A)のカチオン性ポリマーの電荷密度は、すすぎ時のベタつきのなさ、すすぎ時の滑らかさ、寝ぐせのつきにくさ、１日後のまとまりの持続性、１日後の滑らかさの持続性、及び耐シャンプー性の観点から、3.0meq/g以上であって、好ましくは3.5meq/g以上、より好ましくは4.0meq/g以上、更に好ましくは4.5meq/g以上、更に好ましくは5.0meq/g以上、更に好ましくは5.5meq/g以上であり、また、同様の観点から、24meq/g以下であって、好ましくは10meq/g以下、より好ましくは7.0meq/g以下、更に好ましくは6.5meq/g以下である。 ● Hair treatment agent (component (A): cationic polymer with charge density of 3.0 meq / g or more and 24 meq / g or less)
The charge density of the cationic polymer of component (A) is as follows: no stickiness at the time of rinsing, smoothness at the time of rinsing, difficulty of falling asleep, persistence of a unit after one day, persistence of smoothness after one day, From the viewpoint of shampoo resistance, it is 3.0 meq / g or more, preferably 3.5 meq / g or more, more preferably 4.0 meq / g or more, further preferably 4.5 meq / g or more, and further preferably 5.0 meq / g. Or more, more preferably 5.5 meq / g or more, and from the same viewpoint, it is 24 meq / g or less, preferably 10 meq / g or less, more preferably 7.0 meq / g or less, still more preferably 6.5 meq / g. g or less.
　ここで、カチオン性ポリマーの電荷密度とは、ポリマー上の正電荷の数と該ポリマーの分子量の比を指す。カチオン性ポリマーの電荷密度にポリマー分子量を乗じると、所定のポリマー鎖における正に荷電した部位の数が求められる。カチオン性ポリマーの電荷密度は、ポリマーの１ｇ当たりの正電荷（カチオン性を有する窒素原子）のミリ当量数（meq/g）として定義される。下記成分(B)のカチオン性ポリマーの電荷密度も同様である。 Here, the charge density of the cationic polymer refers to the ratio of the number of positive charges on the polymer to the molecular weight of the polymer. Multiplying the charge density of the cationic polymer by the polymer molecular weight gives the number of positively charged sites in a given polymer chain. The charge density of a cationic polymer is defined as the number of milliequivalents (meq / g) of positive charges (cationic nitrogen atoms) per gram of polymer. The charge density of the cationic polymer of the following component (B) is the same.
