Description

毛髪化粧料Hair cosmetics
 本発明は、ベシクル構造体を含む毛髪化粧料に関する。 The present invention relates to a hair cosmetic containing a vesicle structure.
 近年、パーマやヘアカラー、ブリーチなどの利用が一般化する反面、これらの化学処理に伴う毛髪のダメージも問題となっている。従来から、毛髪のダメージを軽減し、シャンプー後の毛髪の感触を向上させるために、リンス、コンディショナー、トリートメントなどの各種毛髪化粧料が使用されている。 In recent years, the use of perms, hair colors, bleaches, etc. has become common, but damage to hair associated with these chemical treatments has also become a problem. Conventionally, various hair cosmetics such as rinses, conditioners and treatments have been used to reduce hair damage and improve the feel of hair after shampooing.
 このような毛髪のダメージを軽減する方法として、まず、油分や活性剤等の各種成分を使用することが挙げられる。例えば、特許文献1は、長鎖アルコールと油剤等とを安定に配合でき、かつ湿潤時に柔軟性、平滑性などの効果に優れる毛髪化粧料であって、特定の第3級アミン、直鎖又は分岐状の脂肪酸、無機酸又は有機酸を含有する毛髪化粧料が開示されている。また、特許文献2は、化学処理、ドライヤーによる乾燥、日々のヘアケア行動などの行為によって生じる毛髪の損傷・疲労破壊を修復又は抑止し、また湿潤時から乾燥後までの毛髪に対する処理段階において良好な柔軟性及びしなやかな感触を付与する毛髪化粧料であって、特定の分岐脂肪酸又はその塩、特定の第3級アミン又はその塩及び必要に応じて特定の芳香族アルコールを含有する毛髪化粧料が開示されている。さらに、特許文献3は、α-ヒドロキシモノカルボン酸又はその塩と特定の芳香族アルコールとを組み合わせた毛髪化粧料は、毛髪に対して柔軟性を持続的に維持し、特に硬い髪も柔らかく保つ効果を付与することができ、かつ毛髪のまとまり性に優れることが開示されている。 As a method for reducing such hair damage, first, various components such as oil and activator can be used. For example, Patent Document 1 is a hair cosmetic that can stably blend a long-chain alcohol and an oil agent and has excellent effects such as flexibility and smoothness when wet, and is a specific tertiary amine, linear or Hair cosmetics containing branched fatty acids, inorganic acids or organic acids are disclosed. Patent Document 2 repairs or suppresses hair damage and fatigue destruction caused by chemical treatment, drying with a dryer, daily hair care behavior, and the like, and is good in the treatment stage for hair from wet to dry. A hair cosmetic that imparts flexibility and a supple feel, comprising a specific branched fatty acid or a salt thereof, a specific tertiary amine or a salt thereof, and, if necessary, a specific aromatic alcohol. It is disclosed. Further, Patent Document 3 discloses that a hair cosmetic comprising a combination of α-hydroxymonocarboxylic acid or a salt thereof and a specific aromatic alcohol continuously maintains flexibility with respect to hair, and particularly keeps hard hair soft. It is disclosed that an effect can be imparted and that the hair is well-organized.
 一方、頭髪に対して有効物質の浸透を促進させる方法として、特許文献4には、トリートメント組成物中にコレステロールを混在させ、塩基性アミノ酸と脂肪酸及び非イオン活性剤で安定化した多層小胞分散物からなる頭髪トリートメント組成物が開示されている。
 また、特許文献5には、特定の分岐脂肪酸を、特定の第3級アミン及び特定の有機酸と組合せてベシクルを形成させて毛髪化粧料に用いることで、分岐脂肪酸量を低減しているにもかかわらず、柔軟性、平滑性、しっとり感、しなやかさが向上する毛髪化粧料が開示されている。
On the other hand, as a method for promoting the penetration of an active substance into the hair, Patent Document 4 discloses a multilayer vesicle dispersion in which cholesterol is mixed in a treatment composition and stabilized with a basic amino acid, a fatty acid and a nonionic active agent. A hair treatment composition comprising an article is disclosed.
Patent Document 5 discloses that the amount of branched fatty acids is reduced by using a specific branched fatty acid in combination with a specific tertiary amine and a specific organic acid to form a vesicle for use in hair cosmetics. Nevertheless, hair cosmetics that improve flexibility, smoothness, moist feeling, and flexibility have been disclosed.

A vesicle structure in which the continuous phase is the aqueous phase can be suitably produced by performing the step of phase inversion emulsification while adding the aqueous phase to the phase (step 3) and the step of cooling the mixture obtained in step 2.
 工程1においては安定的な製造の観点から油相の融点(mp)以上の温度(T=mp+Δ,Δ≧0)で溶解することが好ましく、Δは、5℃以上が好ましく、10℃以上がより好ましい。すなわち、溶解温度は、油相の融点以上であることが好ましく、融点より5℃以上高いことがより好ましく、更に融点より10℃以上高いことが好ましい。また、油相温度の上限は95℃以下が好ましく、90℃以下がより好ましく、85℃以下であることがさらに好ましい。また、油相は均一に混合された状態であることが好ましく、例えば、油相を攪拌、混合しながら溶解させることが好ましい。 In step 1, it is preferable to dissolve at a temperature equal to or higher than the melting point (mp) of the oil phase (T = mp + Δ, Δ ≧ 0) from the viewpoint of stable production, and Δ is preferably 5 ° C. or higher, and preferably 10 ° C. or higher.

However, after the viscosity of the vesicle dispersion reaches a peak, even if the aqueous phase is further dropped into the oil phase, the viscosity of the vesicle dispersion decreases and the vesicle volume concentration also decreases.
