Abstract
Description
本発明は、毛髪又は繊維の絡まり防止方法に関する。 The present invention relates to a method for preventing entanglement of hair or fibers.
毛髪は生活環境（太陽光による紫外線や熱）、日常のヘアケア行動（洗髪やブラッシングによる摩擦）、化学処理（カラーリング、パーマ等）によりダメージを受けている。ダメージを受けた毛髪が擦れ合うと、表面に大きな摩擦力が発生し、絡まりが生じる。「毛髪の絡まり」は、ヘアケア行動におけるあらゆるストレスの原因となる。洗髪時にシャンプー等の毛髪洗浄剤を泡立てる操作中の指通りの悪さ、洗髪後の毛髪のすすぎ時の指通りの悪さ等で「毛髪の絡まり」は感知される。
洗髪後の毛髪の絡まりを解く方法として、コンディショナーやトリートメント等の毛髪化粧料を用いる場合は、これら毛髪化粧料を毛髪に塗布し絡まり部位に指を通しながら馴染ませることによって、毛髪表面に潤滑成分を行き渡らせながら毛髪の絡まりを解いている。従来の技術では、毛髪の指通りや櫛通りをよくする目的で、コンディショナーやトリートメント等の毛髪化粧料にカチオン性界面活性剤、高級アルコール、シリコーン等が配合されている。
Hair is damaged by the living environment (ultraviolet rays and heat from sunlight), daily hair care behavior (rubbing by washing and brushing), and chemical treatment (coloring, perm, etc.). When damaged hair rubs against each other, a large frictional force is generated on the surface, causing entanglement. "Hair entanglement" causes all stress in hair care behavior. "Hair entanglement" is detected by poor finger passage during the operation of whipping hair detergent such as shampoo when washing hair, and poor finger passage during rinsing of hair after washing.
When using hair cosmetics such as conditioners and treatments as a method of untangling the hair after washing, apply these hair cosmetics to the hair and let it blend in while passing the finger through the entangled part, thereby lubricating the hair surface. Untangling the hair while spreading it around. In the conventional technique, a cationic surfactant, a higher alcohol, silicone and the like are blended in hair cosmetics such as conditioners and treatments for the purpose of improving the passage of fingers and combs of hair.
特許文献１には、ポリエーテルアミノ変性シリコーンとカチオン界面活性剤を用いた毛髪化粧料が、濯ぎ時、水流中での毛髪のきしみ感を抑制し、柔軟性や平滑性を向上させることで、濯ぎ時の毛髪の絡みによる損傷を予防できることが開示されている。
特許文献２には、特定の動粘度範囲にあるアミノ変性シリコーンと、アミノポリエーテル変性シリコーンと、特定の動粘度範囲にあるジメチルポリシロキサンと、特定のアルキル型カチオンと、特定の高級アルコールを組み合わせた毛髪化粧料が毛髪の水分保持力を高めながらも、使用時の指どおりを改善し、しなやかでしっとりとした仕上がり感を与えることができ、かつ、低湿度下でのパサツキ防止とうるおい感を与えられることが開示されている。
According to Patent Document 1, a hair cosmetic using a polyether amino-modified silicone and a cationic surfactant suppresses the squeaky feeling of hair in a stream of water during rinsing, and improves flexibility and smoothness. It is disclosed that damage due to hair entanglement during rinsing can be prevented.
Patent Document 2 describes a combination of an amino-modified silicone having a specific kinematic viscosity range, an aminopolyether-modified silicone, a dimethylpolysiloxane having a specific kinematic viscosity range, a specific alkyl-type cation, and a specific higher alcohol. While the hair cosmetics enhance the moisture retention of the hair, it improves the finger passage during use, gives a supple and moist finish, and prevents dryness and moisturizes under low humidity. It is disclosed that it is given.
特許文献１及び２には、毛髪の絡まりを抑制及び解消すること、特に、手を通すなどの操作を行うことなく自発的に毛髪の絡まりを解くことについては開示されていない。
さらにコンディショナーやトリートメント等の毛髪化粧料においては、毛髪の絡まりを抑制するだけでなく、処理後の毛流れが揃い、良好な仕上がりが得られるという効果も望まれる。
本発明は、絡まりが生じやすい毛髪又は繊維において、絡まりの発生を抑制し、絡まりが生じた場合にも手を通すなどの操作を行うことなく自発的に絡まりを解き、且つ毛髪又は繊維の形状を揃えることができる、毛髪又は繊維の絡まり防止方法に関する。
Patent Documents 1 and 2 do not disclose suppressing and eliminating hair entanglement, and in particular, voluntarily removing hair entanglement without performing an operation such as passing through a hand.
Further, in hair cosmetics such as conditioners and treatments, it is desired that not only the entanglement of hair is suppressed, but also the hair flow after treatment is uniform and a good finish can be obtained.
The present invention suppresses the occurrence of entanglement in hair or fibers that are prone to entanglement, and even when entanglement occurs, the hair or fiber is spontaneously unentangled without any operation such as passing through a hand, and the shape of the hair or fiber. The present invention relates to a method for preventing hair or fiber entanglement, which can be aligned.

[How to prevent entanglement of hair or fibers]
In the method for preventing hair or fiber entanglement of the present invention (hereinafter, also simply referred to as "method of the present invention"), the hair or fiber is divided into the following components (A) and (B) by mass ratio [(A) / ( B)] is characterized by having a step of contacting with a treatment agent contained in an amount of 0.001 or more and 50 or less.
(A) Water-insoluble amino polyether-modified silicone (B) Organic acid or inorganic acid The above-mentioned treatment agent preferably further contains an aqueous medium as the component (C).
By having the above-mentioned steps, the method of the present invention suppresses the occurrence of entanglement in hair or fibers that are likely to be entangled, and even when entanglement occurs, it spontaneously entangles without performing an operation such as passing through a hand. It can be unraveled and the shape of hair or fibers can be aligned. In addition, "containing the component (A) and the component (B)" also means "combined with the component (A) and the component (B)".
本明細書において、毛髪又は繊維の形状が揃った状態とは、処理後の毛髪又は繊維が一方向に揃っている状態を意味する。以下、毛髪の形状が揃っていることを「毛流れが揃う」ともいう。毛流れが揃った状態であるか否かは、例えばＢｏｓｓａ Ｎｏｖａ Ｔｅｃｈｎｏｌｏｇｙ社製の毛髪角度測定装置「ＲＵＭＢＡ」を用いて、実施例に記載の方法により毛流れの角度を測定し、その角度のばらつき度合いにより評価することができる。 In the present specification, the state in which the shapes of the hairs or fibers are aligned means the state in which the treated hairs or fibers are aligned in one direction. Hereinafter, the fact that the shapes of the hairs are uniform is also referred to as "the hair flow is uniform". Whether or not the hair flow is uniform is determined by measuring the hair flow angle by the method described in the examples using, for example, a hair angle measuring device "RUMBA" manufactured by Bossa Nova Technology. It can be evaluated by the degree.
本発明の方法により上記効果を奏する理由については定かではないが、以下のように推察される。
毛髪や繊維の絡まりの発生を抑制し、絡まりが生じた場合にも自発的に解けるような状態にするには、毛髪又は繊維間に働く摩擦力を低下させることが重要であると考えられる。本発明者らは、毛髪又は繊維間に働く摩擦力を低下させるために、成分（Ａ）である水不溶性アミノポリエーテル変性シリコーンを含有する処理剤を用いることが有効であることを見出した。
アミノポリエーテル変性シリコーンの中でも水不溶性のものを用いると、毛髪又は繊維に吸着しやすく、毛髪又は繊維間に働く摩擦力の低下効果が良好である。その一方で、成分（Ａ）の疎水性が高すぎると処理剤中の溶解性又は分散性が低下し、毛髪又は繊維の処理効果も低下する傾向がある。本発明で用いる処理剤では成分（Ａ）と成分（Ｂ）とを所定の質量比で併用することにより、処理剤及びこれに含まれる水性媒体に対する成分（Ａ）の溶解性又は分散性が向上し、処理剤中の成分（Ａ）が毛髪又は繊維に有効に作用して摩擦力の低下効果が良好になると考えられる。
さらには、摩擦力が低下して毛髪又は繊維の絡まりが自発的に解けた結果、水から引き揚げる際の弱い水流の力でも、処理後の毛髪又は繊維を一方向に揃えることができるという効果を奏すると考えられる。
The reason why the above effect is obtained by the method of the present invention is not clear, but it is presumed as follows.
It is considered important to reduce the frictional force acting between the hair or fibers in order to suppress the occurrence of entanglement of hair or fibers and to make the state spontaneously unravel even when entanglement occurs. The present inventors have found that it is effective to use a treatment agent containing a water-insoluble aminopolyether-modified silicone as a component (A) in order to reduce the frictional force acting between hairs or fibers.
When a water-insoluble one among the aminopolyether-modified silicones is used, it is easily adsorbed on the hair or fibers, and the effect of reducing the frictional force acting between the hairs or fibers is good. On the other hand, if the hydrophobicity of the component (A) is too high, the solubility or dispersibility in the treatment agent tends to decrease, and the treatment effect of hair or fibers tends to decrease. In the treatment agent used in the present invention, by using the component (A) and the component (B) together in a predetermined mass ratio, the solubility or dispersibility of the component (A) in the treatment agent and the aqueous medium contained therein is improved. However, it is considered that the component (A) in the treatment agent effectively acts on the hair or fibers to improve the effect of reducing the frictional force.
Furthermore, as a result of the reduced frictional force and the spontaneous disentanglement of the hair or fibers, the effect is that the treated hair or fibers can be aligned in one direction even with the force of a weak water flow when the hair or fibers are pulled out of the water. It is thought to play.
例えば本発明の方法を毛髪に適用し、毛髪の絡まりが解けた状態でタオルドライを行うことで、毛髪とタオルとの接触面積が増大して毛髪の水分がタオルに速く吸収される。またドライヤー乾燥時や自然乾燥時には毛髪と空気との接触面積が増大して毛髪中の水分が速く蒸散するため、毛髪の乾燥速度が向上すると考えられる。
さらに本発明の方法によれば、毛髪に手を通すなどの操作を行わなくても自発的に毛髪の絡まりが解けて且つ毛流れが揃うので、処理後のスタイリングが容易になり、乾燥後の毛髪の仕上がりが良好になる。
For example, by applying the method of the present invention to hair and performing towel drying in a state where the entanglement of the hair is disentangled, the contact area between the hair and the towel is increased and the moisture of the hair is quickly absorbed by the towel. Further, it is considered that the drying rate of the hair is improved because the contact area between the hair and the air increases and the moisture in the hair evaporates rapidly during the drying with a dryer or the natural drying.
Further, according to the method of the present invention, the entanglement of the hair is spontaneously disentangled and the hair flow is aligned without performing an operation such as passing the hair through the hair, so that the styling after the treatment becomes easy and the hair is dried. The finish of the hair is improved.
発明の効果を有効に得る観点から、本発明の方法を適用する対象物は毛髪であることが好ましい。すなわち本発明の方法に用いる処理剤は、好ましくは毛髪処理剤である。
処理剤の剤型には特に制限はなく、毛髪又は繊維を処理剤に接触させる方法に応じて、例えば液体状、泡状、ペースト状、クリーム状、固形状、粉末状等、任意の剤型とすることが可能である。毛髪又は繊維を処理剤に浸漬することにより接触させる場合は、液体状であることが好ましい。

The dosage form of the treatment agent is not particularly limited, and any dosage form such as liquid, foam, paste, cream, solid, powder, etc., depending on the method of contacting the hair or fiber with the treatment agent.

表１より、以下のことが判る。
実施例１〜１０の方法により処理された毛髪は、比較例１〜７よりもくし通し荷重平均値が低く毛髪の絡まりを解く効果が高い。また、毛流れの角度の標準偏差の値も小さく、処理後の毛流れが揃っている。
実施例１と比較例６、実施例３と比較例１、実施例４と比較例２との対比によれば、成分（Ａ）を含有する処理剤に成分（Ｂ）である乳酸を所定の質量比で添加すると処理剤の透過度が向上している。これは、処理剤中の成分（Ａ）の分散性又は溶解性が向上していることによるものと推察される。なお実施例１及び２で使用した成分（Ａ）は、成分（Ｂ）を添加しないと全く水に分散せず、水中で大きな塊として存在している状態になった。そのため実施例１及び２に対しては、成分（Ｂ）を含有しない処理剤を用いた比較評価を行うことができなかった。
また処理剤において、成分（Ａ）に替えて水溶性のアミノポリエーテル変性シリコーンを用いた比較例３〜５、質量比［（Ａ）／（Ｂ）］が５０超である比較例６、及び質量比［（Ａ）／（Ｂ）］が０．００１未満である比較例７ではいずれも本発明の効果が得られなかった。
From Table 1, the following can be seen.
The hair treated by the methods of Examples 1 to 10 has a lower average combing load than Comparative Examples 1 to 7, and has a high effect of untangling the hair. In addition, the value of the standard deviation of the hair flow angle is also small, and the hair flow after treatment is uniform.
According to the comparison between Example 1 and Comparative Example 6, Example 3 and Comparative Example 1, and Example 4 and Comparative Example 2, a treatment agent containing the component (A) contains lactic acid as the component (B). When added by mass ratio, the permeability of the treatment agent is improved. It is presumed that this is because the dispersibility or solubility of the component (A) in the treatment agent is improved. The component (A) used in Examples 1 and 2 did not disperse in water at all unless the component (B) was added, and was in a state of existing as a large mass in water. Therefore, it was not possible to carry out comparative evaluation of Examples 1 and 2 using a treatment agent containing no component (B).
Further, in the treatment agent, Comparative Examples 3 to 5 in which a water-soluble aminopolyether-modified silicone was used instead of the component (A), Comparative Example 6 in which the mass ratio [(A) / (B)] was more than 50, and In Comparative Example 7 in which the mass ratio [(A) / (B)] was less than 0.001, the effect of the present invention could not be obtained.
本発明の方法によれば、絡まりが生じやすい毛髪又は繊維において、絡まりの発生を抑制し、絡まりが生じた場合にも手を通すなどの操作を行うことなく自発的に絡まりを解くことができ、さらには毛髪又は繊維の形状を揃えることができる。例えば本発明の方法を毛髪に適用すると、洗浄及びタオルドライ後の毛髪の絡まりを防止することができるので毛髪を短時間で乾燥させることができ、且つ毛流れが揃うので乾燥後の仕上がりが良好になる。 According to the method of the present invention, in hair or fibers that are prone to entanglement, the occurrence of entanglement can be suppressed, and even when entanglement occurs, the entanglement can be voluntarily released without performing an operation such as passing through a hand. Furthermore, the shape of hair or fibers can be made uniform. For example, when the method of the present invention is applied to hair, it is possible to prevent entanglement of hair after washing and towel drying, so that the hair can be dried in a short time, and the hair flow is uniform, so that the finish after drying is good. become.
