Description
本発明は、水性毛髪洗浄剤に関する。 The present invention relates to an aqueous hair cleansing agent.
服装やメイクはもちろん、髪の印象は非常に大切である。普段の生活の中で、髪がつぶれて思うようなヘアスタイルに決まらないことは、印象を低下させるため不満点の1つである。したがって、ボリューム感のある毛髪が求められている。しかし、毛髪は、年齢を重ねるとともにボリュームが低下してしまうため、これを改善するニーズが非常に高まっている。 The impression of hair as well as clothes and makeup is very important. It is one of the dissatisfaction points to reduce the impression that the hair style that the hair breaks in everyday life is not decided. Therefore, there is a demand for hair with a sense of volume. However, since the volume of hair decreases with age, there is a great need for improving this.
一方、水性毛髪洗浄剤には、毛髪への様々な効果が期待されている。水性毛髪洗浄剤の主界面活性剤の一つとして、従来からアニオン界面活性剤が用いられている。例えば、特許文献1には、毛髪の乾燥後のさらさら感、コンディショニング効果を高める為に、アニオン界面活性剤と水不溶性シリコーンエラストマー粉体を用いる技術が開示されている。また、例えば、特許文献2、3には、乾燥後の感触、すすぎ時の感触を高める為に、アニオン界面活性剤と特定のカチオン化ポリマーを用いる技術が開示されている。
On the other hand, various effects on hair are expected from aqueous hair cleansing agents. Conventionally, anionic surfactants have been used as one of the main surfactants for aqueous hair cleansing agents. For example,
しかしながら、従来の水性毛髪洗浄剤では、濡れた毛髪の乾燥過程において、毛髪が頭皮にはりついたり、毛髪同士がくっつきあうことで毛髪が束になりやすく、乾燥後の毛髪にボリューム感を付与できるものではなかった。 However, with conventional aqueous hair cleansing agents, in the process of drying wet hair, the hair tends to bind to the scalp and the hairs stick together, giving a sense of volume to the dried hair It wasn't.
本発明は、かかる事情を鑑みてなされたものであり、濡れた毛髪の乾燥過程において、毛髪を1本1本ばらけ易くし、毛髪の根元を立ち上げることにより、乾燥後の毛髪にボリューム感が得られる水性毛髪洗浄剤を提供するものである。 The present invention has been made in view of such circumstances. In the drying process of wet hair, the hair is easily separated and the volume of the hair after drying is raised by raising the root of the hair. An aqueous hair cleansing agent that can be obtained is provided.
本発明者は、アニオン性界面活性剤、カチオン化ガラクトマンナン及び特定のカチオン性基含有共重合体を組み合わせて用いることで、弾性固体粒子を毛髪表面に残留させやすくして、上記課題を解決できる水性毛髪洗浄剤が得られることを見出した。 The present inventor can solve the above-mentioned problems by using an anionic surfactant, a cationized galactomannan, and a specific cationic group-containing copolymer in combination to easily leave elastic solid particles on the hair surface. It has been found that an aqueous hair cleanser can be obtained.
すなわち、本発明によれば、
次の成分(A)〜(D):
(A)アニオン性界面活性剤
(B)カチオン化ガラクトマンナン
(C)弾性固体粒子
(D)次の単量体(a1)、(a2)及び(a3)を含有するモノマー混合物を共重合することにより得られるカチオン性基含有共重合体、を含む水性毛髪洗浄剤が提供される。
単量体(a1):一般式(I)又は(II)で表される親水性ノニオン性基含有ビニル単量体の少なくとも1種

A method for measuring the amount of rising hair will be described with reference to the
An aqueous solution in which the hair cosmetic was diluted 20 times with ion-exchanged water was used as a sample aqueous solution.
As shown in FIG. 2, using the
As shown in FIG. 3, the maximum value of the height of the bent portion of the hair bundle immediately after rinsing is (h1), and the maximum value of the height of the bent portion of the hair bundle after drying is set high as shown in FIG. The rising amount (Δh = h2−h1) was used as (h2).
表1より、実施例の組成物では、濡れた状態での毛髪が1本1本ばらけ易く、乾燥後さらさらし、乾燥後の毛髪の根元を立ち上げることにより、乾燥後の毛髪にボリュームアップ効果に優れていたことが分かった。 From Table 1, in the compositions of the examples, the hairs in the wet state are easily separated one by one, and after drying, the hair is dried, and the roots of the dried hair are raised to increase the volume of the hair after drying. It turned out that the effect was excellent.

(コアセルベートの観察実験)
上記実施例1、比較例1及び比較例5で得られた水性毛髪洗浄剤を用いて、コアセルベートの観察を行った。
(Coacervate observation experiment)
The coacervate was observed using the aqueous hair cleansing agents obtained in Example 1, Comparative Example 1 and Comparative Example 5.
<評価方法>
まず、各ガラス瓶(容量:110ml、胴径×高さ(mm)51.5×95.5)に、上記実施例1、比較例1及び比較例5で得られた水性毛髪洗浄剤を10g加え、さらに水を90g加え、全量をそれぞれ100gとした。
次に、ペンシルミキサー(モーター回転数:無負荷7000rpm、モータートルク:8g/cm2、モーター起動トルク:28g/cm2、本体サイズ:φ20×172mm、シャフトサイズ:軸/φ3mm・先端/φ8mm・全長/115mm、シャフト材質:軸/ステンレス(SUS304フッ素樹脂塗装)、先端/PCTFE(フッ素樹脂))で、30秒攪拌し、そのまま放置し、50分静置した後の各ガラス瓶の中の状態を観察、撮影し、その結果を図5に示した。
<Evaluation method>
First, 10 g of the aqueous hair cleansing agent obtained in Example 1, Comparative Example 1 and Comparative Example 5 was added to each glass bottle (capacity: 110 ml, trunk diameter × height (mm) 51.5 × 95.5). Further, 90 g of water was added to make the total amount 100 g.
Next, a pencil mixer (motor rotation speed: no load 7000 rpm, motor torque: 8 g / cm 2 , motor starting torque: 28 g / cm 2 , body size: φ20 × 172 mm, shaft size: shaft / φ3 mm, tip / φ8 mm, total length / 115mm, shaft material: shaft / stainless steel (SUS304 fluororesin coating), tip / PCTFE (fluororesin)), stirred for 30 seconds, left as it is, and allowed to stand for 50 minutes to observe the state in each glass bottle The results are shown in FIG.
図5に示すように、各ガラス瓶の中に見える白色の粉体が、コアセルベートとそれに取り込まれたシリコーンエラストマーである。実施例1は、成分(A)〜(D)の複合体であり、比較例1は、成分(A)〜(C)の複合体、比較例5は、成分(A)、(C)、カチオン化ヒドロキシエチルセルロースの複合体である。図5より、実施例1では、比較例1、比較例5よりも嵩高く、白色粉体が沈降しにくい状態であることが観察された。これにより、実施例1の水性毛髪洗浄剤では、洗髪中もコアセルベートやシリコーンエラストマーが毛髪に付着しやすい状態になっているため、毛髪表面に残留しやすいと考えられる。 As shown in FIG. 5, the white powder visible in each glass bottle is coacervate and the silicone elastomer incorporated therein. Example 1 is a complex of components (A) to (D), Comparative Example 1 is a complex of components (A) to (C), and Comparative Example 5 is a component (A), (C), It is a complex of cationized hydroxyethyl cellulose. From FIG. 5, in Example 1, it was observed that it was bulky compared with the comparative example 1 and the comparative example 5, and it was a state which white powder did not settle easily. Thereby, in the aqueous hair cleansing agent of Example 1, since coacervate and a silicone elastomer are in the state which adheres to hair easily even during hair washing, it is thought that it remains on the hair surface easily.
