Description
本発明は、特定の硫酸塩型界面活性剤を含有する毛髪洗浄剤に関する。 The present invention relates to a hair cleansing agent containing a specific sulfate type surfactant.
近年、シャンプーの性能として、洗浄力、泡立ちの良さ、豊富な泡量等の基本性能はもちろんのこと、泡立て時の泡の滑り感やすすぎ時の滑り感に優れること、きしみ感が無いことなども望まれるようになっている。ドデシル硫酸ナトリウムに代表されるアルキル硫酸塩は、その洗浄力の高さと起泡量の多さから、水性洗浄剤の洗浄成分として最も多く用いられてきた。しかし、アルキル硫酸塩を単独で用いた場合、洗浄時にきしみ感がある点が大きな問題であった。 In recent years, shampoo performance includes not only basic performances such as detergency, good foaming, abundant amount of foam, but also excellent slipping feeling when foaming, slipping feeling when overlying, and no squeaky feeling. Is also desired. Alkyl sulfates typified by sodium dodecyl sulfate have been most frequently used as cleaning components in aqueous cleaning agents because of their high detergency and large amount of foaming. However, when an alkyl sulfate is used alone, a serious problem is that it has a squeaky feeling during cleaning.
そこで、感触を向上するためにアルキル基と硫酸基の間にエチレンオキシドを付加させたポリオキシエチレン付加型アルキル硫酸塩（アルキルエーテル硫酸塩）、特にエチレンオキシドが平均２〜３モル付加したものが、洗浄時の感触の良さからシャンプーに配合され使用されるようになった。しかしながら、アルキルエーテル硫酸塩の使用によりきしみ感は解消したが、アルキル硫酸塩が本来有していた泡立ちの速さの点が大きく劣るようになり、泡立ちの良さとすすぎ時のきしみ感のなさを両立するには不十分であった。そこで、アルキル硫酸塩とアルキルエーテル硫酸塩を混合することで泡立ちはやや改善されるものの、すばやい泡立ちと良好な泡の感触を両立するには不十分であった。 Therefore, a polyoxyethylene addition type alkyl sulfate (alkyl ether sulfate) in which ethylene oxide is added between an alkyl group and a sulfate group in order to improve the feeling, especially an average addition of 2 to 3 moles of ethylene oxide is washed. Because of the good feel of the time, it has been used in shampoos. However, the use of alkyl ether sulfate eliminated the squeaky feeling, but the alkyl sulphate inherently had a much lower foaming speed, and the good foaming and lack of squeaky feeling during rinsing. It was insufficient to achieve both. Therefore, although the foaming is slightly improved by mixing the alkyl sulfate and the alkyl ether sulfate, it is insufficient to achieve both quick foaming and good foam feel.
また、アルキルエーテル硫酸塩のEO付加モル数を調整して毛髪洗浄剤の性能を改善しようとする技術として、EO付加モル数１〜８のアルキルエーテル硫酸塩及び両性界面活性剤を含む界面活性剤成分５〜50重量を含み、付加モル数１モル以下であるアルキルエーテル硫酸塩を５重量％より少なく含む水性シャンプー組成物（特許文献１）が提案されている。しかしながら、泡立ち、泡質いずれの点においても満足できるものではなかった。 Further, as a technique for improving the performance of a hair washing agent by adjusting the number of moles of EO addition of alkyl ether sulfate, a surfactant containing an alkyl ether sulfate having 1 to 8 moles of EO addition and an amphoteric surfactant. There has been proposed an aqueous shampoo composition (Patent Document 1) containing less than 5 wt% of an alkyl ether sulfate containing 5 to 50 wt% of the component and having an added mole number of 1 mol or less. However, neither foaming nor foam quality was satisfactory.
一方、毛髪は、常にドライヤー熱、ブラッシング等の日常的なヘアケア行為による物理的刺激、及び洗髪、パーマ、ヘアカラー、ブリーチ等による化学的刺激に曝されているため、毛髪内部成分や構造体の部分的欠損を伴う損傷状態にある。このため、保護・修復機能の発現にシリコーン油等の油剤が加えられている。しかし、これら油剤は、配合量が増えると泡立ち、すすぎ時の指通り等のシャンプーとしての基本性能が低下するという問題があった。 On the other hand, hair is always exposed to physical stimuli due to daily hair care such as dryer heat and brushing, and chemical stimuli such as shampoo, perm, hair color, bleach, etc. It is in a damaged state with a partial defect. For this reason, an oil agent such as silicone oil is added to the expression of the protective / restoring function. However, these oil agents have a problem that the basic performance as a shampoo such as foaming and fingering at the time of rinsing decreases as the blending amount increases.
そこで、本発明は、洗髪時には良好な泡立ちと滑りの良い泡質を有し、すすぎ時には滑らかな感触を有し、仕上がりの毛髪には柔らかさ及びしなやかな感触を与え、かつ、特にヘアカラーなどの傷みの蓄積による毛髪損傷・疲労破壊を修復又は抑止できる毛髪洗浄剤を提供することを目的とする。 Therefore, the present invention has good foaming and slippery foam quality at the time of shampooing, has a smooth feel at the time of rinsing, gives the finished hair a soft and supple feel, and especially hair color etc. An object of the present invention is to provide a hair cleaning agent capable of repairing or inhibiting hair damage and fatigue destruction due to accumulation of hair damage.
本発明者らは、ポリオキシエチレン付加型アルキル硫酸塩において、エチレンオキシドの付加モル数が少ない側に分布している硫酸塩、すなわち付加モル数０〜２の硫酸塩の比率が一定範囲内にある硫酸塩成分と、両性界面活性剤と、特定の分岐脂肪酸とを併用した場合に、上記要求を満たす毛髪洗浄剤が得られることを見出した。 In the polyoxyethylene addition type alkyl sulfate, the present inventors have a ratio of sulfate distributed on the side where the number of added moles of ethylene oxide is small, that is, the ratio of sulfates having 0 to 2 added moles within a certain range. It has been found that when a sulfate component, an amphoteric surfactant and a specific branched fatty acid are used in combination, a hair cleanser that satisfies the above requirements can be obtained.

Examples 1-5, Comparative Examples 1-4
Using the sulfate type surfactants shown in Table 1, the hair cleansing agents shown in Table 2 were prepared, and “speed of foaming”, “smooth feeling during hair washing”, “after drying” according to the following methods and standards The hair flexibility "," the smoothness of the hair after drying "and" the suppleness of the hair after drying "were evaluated. In addition, a fatigue resistance test was performed.
「泡立ちの速さ」
図１に示す装置を用いて、泡立ちの速さを評価した。
図１の装置は、底面に排水口（図示せず）を有し、上面が開口している透明プラスチック製筒状容器10（直径160mm，高さ55mm）、透明プラスチック製蓋20、モーター30を内蔵したコントロールユニット40、計量器50、トルク検出器60を備えている。この容器10内には、図２に示す複数の植毛孔Ｐに毛髪１（90mm，計30ｇ）を植毛した円板11（直径略160mm）が装着されている。容器10は、モーター30によって矢印ｘの方向に回転し、それにより容器10内の毛髪１も回転する。
蓋20の裏面には、人の指に相当する第１の突起物21（直径15mm、高さ12mmの円柱状突起物×３個）と、ブラシに相当する第２の突起物22（縦10mm、横２mm、高さ12mmの突起物×９個）が、蓋20を矢印ｙのように容器10の上面に被せたとき毛髪１に接触するように設けられている。また、蓋20には、洗浄剤注入用のロート状注入孔25が設けられている。蓋20は、容器10に被せられたとき、容器10に固定されず、支柱41にトルク検出器60や計量器50を介して支持されている。従って、容器10に蓋20を被せ、容器10を回転させると、容器10内の毛髪１と突起物21、22とが摺動する。よって、注入孔25から毛髪１に洗浄剤をかけると、実際の毛髪の洗髪に近い状態で洗浄剤を起泡させることができる。
まず、毛髪を水30ｇでぬらし、ラノリンからなるモデル皮脂0.3mLを加えた後、評価サンプル1.5mLをかけた。次に毎分70回転で容器10を回転させて毛髪１と突起物21、22とを摺動させ、生じた泡を計量器50に捕集し、泡量が25mLになるまでの時間により、下記基準に従って評価した。
"Speed of foaming"
The speed of foaming was evaluated using the apparatus shown in FIG.
The apparatus of FIG. 1 has a drainage port (not shown) on the bottom surface, a transparent plastic cylindrical container 10 (diameter 160 mm, height 55 mm) with an open top surface, a transparent plastic lid 20 and a motor 30. It has a built-in control unit 40, measuring instrument 50, and torque detector 60. In this container 10, a disk 11 (approximately 160 mm in diameter) in which hair 1 (90 mm, 30 g in total) is implanted in a plurality of flock holes P shown in FIG. The container 10 is rotated by the motor 30 in the direction of the arrow x, whereby the hair 1 in the container 10 is also rotated.
On the back surface of the lid 20, there are a first protrusion 21 corresponding to a human finger (3 columnar protrusions having a diameter of 15 mm and a height of 12 mm) and a second protrusion 22 corresponding to a brush (vertical 10 mm). 9 projections each having a width of 2 mm and a height of 12 mm are provided so as to come into contact with the hair 1 when the lid 20 is placed on the upper surface of the container 10 as indicated by an arrow y. The lid 20 is provided with a funnel-shaped injection hole 25 for injecting the cleaning agent. When the lid 20 is put on the container 10, it is not fixed to the container 10 and is supported on the support column 41 via the torque detector 60 and the measuring instrument 50. Therefore, when the container 10 is covered with the lid 20 and the container 10 is rotated, the hair 1 and the protrusions 21 and 22 in the container 10 slide. Therefore, when a cleaning agent is applied to the hair 1 from the injection hole 25, the cleaning agent can be foamed in a state close to that of actual hair.
First, the hair was wetted with 30 g of water, 0.3 mL of model sebum composed of lanolin was added, and then 1.5 mL of the evaluation sample was applied. Next, the container 10 is rotated at 70 revolutions per minute to slide the hair 1 and the protrusions 21 and 22 and the generated foam is collected in the measuring instrument 50. Depending on the time until the foam amount reaches 25 mL, Evaluation was made according to the following criteria.

「疲労耐性試験」
Y. K. Kamath, S. B. Hornby, H. D. Weigmann and S. Ruetsch, J. Cos. Sci., 50, 198-200(1999)に記載の方法に従い、50g/毛髪１本の負荷を繰り返し与え、破断までの繰り返し数をカウントした。得られたデータを元に、以下のようにして疲労耐性のパラメータ（特性寿命)を算出した。
疲労破壊現象を統計的に取り扱うため、広範囲にばらつきの特性を評価できる「ワイブル分布」を用いた。ワイブル分布の式(a)において、両辺の自然対数を２回取って得られる式(b)からパラメータθ（特性寿命)を求める。ｘ軸をln x、ｙ軸をln ln [1/[1−F(x)]]とし、各データをプロットして近似直線を求め、切片＝b lnθ、傾き＝ｂからパラメータθを算出する（式(c)）。
"Fatigue resistance test"
According to the method described in YK Kamath, SB Hornby, HD Weigmann and S. Ruetsch, J. Cos. Sci., 50, 198-200 (1999), a load of 50 g / hair was repeatedly applied, and the number of repetitions until breakage Counted. Based on the obtained data, the fatigue resistance parameter (characteristic life) was calculated as follows.
In order to statistically handle the fatigue failure phenomenon, the “Weibull distribution” that can evaluate the characteristics of dispersion over a wide range was used. In the equation (a) of the Weibull distribution, the parameter θ (characteristic life) is obtained from the equation (b) obtained by taking the natural logarithm of both sides twice. The x axis is ln x, the y axis is ln ln [1 / [1-F (x)]], each data is plotted to obtain an approximate straight line, and the parameter θ is calculated from intercept = b lnθ and slope = b. (Formula (c)).
F(x)＝1−exp[-(x/θ)b] (a)
ln ln [1/[1−F(x)]]＝b ln x−b lnθ (b)
θ(特性寿命)＝exp(−切片/傾き) (c)
ｘ：切れたときの回数，F(x)：切れた順番/サンプル数
ｂ：形状パラメータ
θ：特性寿命（サンプル数の63.2％が破壊するまでの回数）
F (x) = 1−exp [-(x / θ) b ] (a)
ln ln [1 / [1−F (x)]] ＝ b ln x−b lnθ (b)
θ (characteristic life) = exp (− intercept / slope) (c)
x: Number of times of cutting, F (x): Order of cutting / number of samples b: Shape parameter θ: Characteristic life (number of times until 63.2% of samples are destroyed)
