Description
【0001】
【発明の属する技術分野】
本発明は、持続的柔軟性、滑潤性に優れた染毛料、特に移染性なく、染毛性等に優れた染毛料に関する。
【0002】
【従来の技術】
従来、毛髪化粧料には毛髪の感触を改善するために、モノ又はジ直鎖状長鎖アルキル第四級アンモニウム塩やモノ又はジ分岐状長鎖アルキル第四級アンモニウム塩等のカチオン性界面活性剤が配合されている。
【0003】
しかしながら、これらの従来の毛髪化粧料は、毛髪の感触、すなわちコンディショニング効果である、しっとり感、平滑性等は優れているが、柔軟性に関しては充分でないという欠点があった。すなわち、漏れている状態では柔軟性があるが乾燥した状態では柔軟性がほとんど失なわれてしまっていた。
そこで、かかる欠点を解決する目的で、高級アルコール、グリセライド、流動パラフィン等の油脂類などを併用していた。これらは、毛髪表面に疎水性分子を残留させて、表面張力を下げて感触的に柔軟感を賦与するもので、これら毛髪表面に残留した物質は、日常生活において経時的に接触、あるいは洗髪等により脱落してしまうため、柔軟性を持続的に維持することは困難であった。また硬い髪は、毛髪の弾性が大きいためにまとまりも悪いことが多いが、従来の表面的な対応では、消費者の要求を満たすことは困難であった。又、毛髪の柔軟性を向上させる手段として、炭素数が6以上の2−ヒドロキシ脂肪酸とコンディショニング成分とを併用する毛髪コンディショニング組成物が提案されている(例えば特開平3−48607号公報、特開平3−48609号公報)。しかし、これらも、柔軟性の効果を持続的に維持する面では未だ十分ではなかった。
つまりは、柔軟性と滑沢性の両方の効果を、持続的に維持するということは困難であった。
【0004】
一方、酸性染料、天然色素を配合した染毛剤は、他の染毛剤に比べて毛髪損傷性の少ないことから家庭で、また美容院で広く使用されている。
しかしながら、当該酸性染料染毛剤は、毛髪に塗布した後にシャンプーで洗い流す際、洗液が不快なほど濃い色素色をしており、シャンプー後タオルや枕カバーに色素液が付着したり、発汗や降雨で毛髪が濡れたときに衣類等に移染してしまうという欠点を有している。
【0005】
このような欠点である染着性、耐色落ち性等を改良するために、特定の酸性染料を用い、グリコール酸及び/又はピロリドンカルボン酸及び/又はそれらのアルカリ金属塩、アルカリ土類金属塩、アミン塩を併用した染毛料組成物も提案されているが(特開平6−298630号)、移染性の点で未だ満足しうるものではない。
【0006】
また、ヘアリンスのような使用方法で多数回使用することにより白髪を目立たなくする染毛剤組成物として、酸性染料、有機溶剤を含有し、pHが2.0〜4.5であり、有機酸の塩等を配合し、緩衝能を0.01〜0.2グラム当量/lとした染毛剤組成物が提案されているが(特開平5−78228号)、染毛には多数回使用することが必要であり、具体的に使用しているクエン酸ナトリウム塩、乳酸ナトリウム塩を配合したものは、移染性、風合いの点で未だ満足しうるものではない。
【0007】
【発明が解決しようとする課題】
本発明は、染毛の際のシャンプー洗液の色が著しく抑えられ、また、衣類、肌等への移染性がなく、鮮やかな色調に染毛することができ、しかも染色性に優れ、染毛後の毛髪のしなやかさ、くし通り性に優れた染毛料を提供することを目的とする。
【0008】
【課題を解決するための手段】
本発明者らは、上記課題を解決すべく鋭意検討を行った結果、炭素数4〜6のβ−ヒドロキシモノカルボン酸又はその塩を配合することにより、染毛時の洗液への色落ちを抑え、移染性を改良できることを見出し、本発明を完成した。

この配合量が1%未満の場合には効果を充分に発揮することができず、また、20%を超えると皮膚刺激がある場合があり、或いは、塩析等により他の成分を安定に配合することが困難になる。
【0012】
色素浸透性を向上させるために、下記一般式(2)で表される芳香族アルコール類を併用することが好ましい。
【化2】

【0018】
上記色素成分の配合量は、染毛料全重量に対し0.01〜2%であるが、染毛力とコスト面から0.02〜1.0%が好ましい。色素成分の配合量が0.01%未満であると、染毛効果が十分に発揮されず、また2%を越えると染毛度は良好であるが、皮膚や衣類に誤って付着したときに、除去しにくいので好ましくない。
【0019】

BACKGROUND OF THE INVENTION
The present invention is sustained flexibility, hair dye excellent in NameraJun properties, particularly migration resistance without relates hair dye excellent in hair and the like.
[0002]
[Prior art]
Conventionally, in order to improve the feel of hair in hair cosmetics, cationic surface activity such as mono- or di-linear long-chain alkyl quaternary ammonium salts and mono- or di-branched long-chain alkyl quaternary ammonium salts An agent is blended.
[0003]
However, these conventional hair cosmetics are excellent in touch, that is, conditioning effect, moist feeling, smoothness, etc., but have a drawback that they are not sufficient in terms of flexibility. That is, there was flexibility in the leaking state, but almost no flexibility was lost in the dry state.
Therefore, for the purpose of solving such drawbacks, oils and fats such as higher alcohols, glycerides and liquid paraffin have been used in combination. These leave hydrophobic molecules on the surface of the hair and lower the surface tension to give a feeling of softness to the touch. Substances remaining on the surface of the hair come into contact with time in daily life or wash hair, etc. It was difficult to maintain the flexibility continuously. In addition, hard hair is often poorly organized due to its high elasticity, but it has been difficult to meet consumer demands with conventional superficial measures. In addition, as a means for improving the flexibility of hair, a hair conditioning composition using a combination of a 2-hydroxy fatty acid having 6 or more carbon atoms and a conditioning component has been proposed (for example, JP-A-3-48607, JP-A-Hei. 3-48609). However, these are still not sufficient in sustaining the flexibility effect.
In other words, it has been difficult to sustain both the flexibility and lubricity effects.
[0004]
On the other hand, hair dyes containing acidic dyes and natural dyes are widely used at home and in beauty salons because they have less hair damage than other hair dyes.
However, when the acid dye hair dye is applied to the hair and washed off with a shampoo, the washing solution has an unpleasant dark color, and the dye solution adheres to the towel or pillow cover after shampooing, sweating, When the hair gets wet due to rain, it has the disadvantage of being transferred to clothing.
[0005]
In order to improve such defects as dyeing property, color fading resistance, etc., a specific acid dye is used, glycolic acid and / or pyrrolidone carboxylic acid and / or alkali metal salt or alkaline earth metal salt thereof. A hair dye composition using an amine salt has also been proposed (Japanese Patent Laid-Open No. 6-298630), but it is still not satisfactory in terms of dye transfer properties.
[0006]
In addition, as a hair dye composition that makes gray hair inconspicuous by using it many times in a usage method such as hair rinse, it contains an acid dye and an organic solvent, has a pH of 2.0 to 4.5, an organic acid A hair dye composition having a buffer capacity of 0.01 to 0.2 gram equivalent / l has been proposed (Japanese Patent Laid-Open No. 5-78228), but used many times for hair dyeing. It is necessary to carry out the above, and the concretely used sodium citrate salt and sodium lactate salt are not yet satisfactory in terms of transferability and texture.
[0007]
[Problems to be solved by the invention]
In the present invention, the color of the shampoo washing solution at the time of hair dyeing is remarkably suppressed, and there is no transferability to clothes, skin, etc., and hair can be dyed in a vivid color tone, and excellent in dyeability. An object of the present invention is to provide a hair dye excellent in suppleness and combability of hair after hair dyeing.
[0008]
[Means for Solving the Problems]
As a result of intensive studies to solve the above-mentioned problems, the present inventors have blended β-hydroxymonocarboxylic acid having 4 to 6 carbon atoms or a salt thereof to discolor the washing liquid during hair dyeing. It was found that the dye transfer property can be improved and the present invention has been completed.
[0009]
That is, according to the present invention, the following general formula (1)
[Chemical 1]
(Wherein R 1 represents a hydrogen atom or an alkyl group having 1 to 3 carbon atoms)
1 to 20% by weight of β-hydroxymonocarboxylic acid or a salt thereof represented by

【Example】
EXAMPLES Next, although an Example is given and this invention is demonstrated, this invention is not limited to these Examples. The performance test method, sensory test method, and evaluation criteria used in this example are as follows.
[0025]
<Test method and evaluation>
(1) In the case of hair dye [Hair dyeing degree]
1 g of each composition shown in Table 1 was uniformly applied to 1 g of a dried goat hair bundle, and then allowed to stand at room temperature for 15 minutes and shampooed. Then, it dried and evaluated the hair dyeing degree ((DELTA) E * ) by the method shown below.
L, a, and b values were measured for the above-mentioned dyed hair bundle with a color difference meter (SPECTRO COLOR METER SE2000 manufactured by Nippon Denshoku Industries Co., Ltd.), and the color difference (ΔE * ) from the undyed hair was determined to evaluate the dyeing. . ΔE * indicates that the larger the value, the better the dyeing.
[Expression 1]
[Transferability]
After dyeing goat hair in the same manner as above, washing it with shampoo, leaving it in place, holding a bundle of hair on a white towel, and assessing the degree of dyeing of the towel after placing a 500 g weight for 5 minutes, the results are shown in Table 1. Shown in The evaluation criteria are as follows.
◎: Pure white ○: If you look closely, you can see faint staining △: Staining is seen, but the degree is light ×: Clearly stained, quite severe [flexibility and combability]
In the same manner as described above, the goat hair was dyed, allowed to stand, washed with shampoo, air-dried, and then the texture and the feeling of combing were evaluated by sensory evaluation. The results are shown in Table 1.
A: The texture is very supple and the comb is very good.
○: The texture is supple and the comb is very good.
Δ: The texture is not supple and the combing is not good.
×: The texture is not supple and the combing is not good.
[0026]
