Description

【0001】
【発明の属する技術分野】
本発明は染毛剤組成物に関する。
【0002】
【従来の技術】
一般に白髪混じりの髪を黒色、褐色等に染める「白髪染め」、或いは金髪、紫色、赤色、オレンジ色、緑色、黄色等髪を好みに合わせて染める「おしゃれ染め」には染毛剤が使用される。このような染毛の種類としては、酸化染料タイプと酸性染料タイプがよく知られている。
前者の酸化染料タイプのものは永久染毛剤と呼ばれ、通常はオルト、パラのフェニレンジアミン等の酸化染料中間体、メタフェニレンジアミンやメタアミノフェノールなどのメタ成分、フェノール類等の発色剤等よりなる第1剤と、過酸化水素、過ホウ酸ナトリウム等の酸化剤よりなる第2剤との二剤型が一般的である。この酸化タイプの染毛剤では、第1剤の酸化染料中間体、発色剤が、第2剤の酸化剤によって毛髪内で酸化され、重合して水に不溶性の色素となり毛髪を染着する。このような酸化タイプの染毛剤は、要望に応じた色調に染毛することができ、しかもその染毛力も優れてはいるが、反面、酸化剤による染毛処理により毛髪が損傷して施術後の毛髪に潤いがなくなったり、或いは酸化染料によってはアレルギーを起こす場合があったり、また頭皮に刺激を与える等の危険性もある。
【0003】
この酸化タイプの染毛剤の他に酸性タイプや塩基性タイプの染料を用いた染毛料がある。一般に、酸性タイプの染毛料は主として酸性染料及びベンジルアルコール、イソプロピルアルコール等の染色助剤、増粘剤、酸、水等からなる。また、塩基性タイプの染毛料は主として塩基性染料、カチオン界面活性剤、増粘剤、水等からなる。これらは染毛料を直接毛髪に吸着させて染毛するものである。とくに塩基性タイプは中性付近で毛髪によく染まるのでここ最近では主流になりつつある。
【0004】
【発明が解決しようとする課題】
ところが、業界において染毛技術が発達したとはいえ、現状の製品よりも染色性が向上し毛髪に対するダメージを低減した、染毛剤組成物の提供が望まれている。また、毛髪に吸着する染毛料は、前記酸化タイプの染毛剤と比べると、危険性が少なく手軽に使用できるが、反面、染毛力がやや低下し、洗髪(シャンプーの使用)による色落ちが生じやすく、しかもその染毛の持続性も短く、一時的なものであった。
【0005】
【問題を解決するための手段】
リン酸エステルと脂肪族アルコールは公知の物質であるが、種々の研究を重ねた結果、特定のリン酸エステル2種類と脂肪族アルコールを混合したものを0.01〜30.0重量%配合することで染毛剤に対しては染色性向上と、頭皮及び毛髪に対するダメージの低減効果の他にアンモニア臭が低減できる。染毛料に対しては染色性を向上しシャンプー退色を防止できることを見出し、本発明を完成するに至った。
【0006】
【発明の実施の形態】
以下、本発明の構成について詳述する。
【0007】
本発明に配合される特定のリン酸エステルは、下記一般式(1)又は(2)で示されるリン酸エステルである。そして、式中の置換基R1とR2は炭素数8〜24、好ましくは8〜18の炭化水素基であり、特に炭素数8〜18の直鎖状アルキル基であることが好ましい。一般式(2)で示されるリン酸エステルの式中R3で表される置換基として炭素数8〜24、好ましくは8〜18の炭化水素基であり、特に炭素数8〜18の直鎖状アルキル基であることが好ましい。nは0〜20の中から選ばれる整数であるが、n=10及びn=20の化合物が好ましい。特定のリン酸エステルとしてはリン酸ジセチル、リン酸モノポリオキシエチレンセチルエーテル等が好適である。脂肪族アルコールとしてはセトステアリルアルコール、セチルアルコール等が好適である。本発明の組成物には、前記構造のリン酸エステル2種類と脂肪族アルコールを配合する。この混合したものを商品名で示すと、クローダジャパン製CRODAFOS CES、CRODAFOS CS-20 ACID等である。

BACKGROUND OF THE INVENTION
The present invention relates to a hair dye composition.
[0002]
[Prior art]
Generally, hair dyes are used for “white hair dyeing” for dyeing hair mixed with white hair into black, brown, etc., or “fashion dyeing” for dyeing hair such as blonde, purple, red, orange, green, yellow, etc. . As such hair dye types, an oxidation dye type and an acid dye type are well known.
The former type of oxidative dyes is called permanent hair dye, and is usually an intermediate of oxidative dyes such as ortho and para phenylenediamine, meta-components such as metaphenylene diamine and metaaminophenol, and color formers such as phenols. A two-component type of a first agent comprising a hydrogen peroxide and a second agent comprising an oxidizing agent such as sodium perborate is common. In this oxidation type hair dye, the intermediate of the first dye and the color former are oxidized in the hair by the second oxidizing agent and polymerize to become a water-insoluble pigment and dye the hair. Such oxidation-type hair dyes can be dyed to the desired color tone and have excellent hair-dyeing power. There is also a risk that the hair afterwards will not be moisturized, or allergic oxidation may occur depending on the oxidative dye, and the scalp may be irritated.
[0003]
In addition to this oxidation type hair dye, there are hair dyes using acidic type and basic type dyes. In general, an acidic type hair dye mainly comprises an acidic dye and a dyeing aid such as benzyl alcohol and isopropyl alcohol, a thickener, acid, water and the like. Basic type hair dyes are mainly composed of basic dyes, cationic surfactants, thickeners, water and the like. These dye hair by directly adsorbing the hair dye on the hair. In particular, the basic type is becoming mainstream recently because it is dyed well in the hair near neutrality.
[0004]
[Problems to be solved by the invention]
However, even though hair dyeing technology has been developed in the industry, it is desired to provide a hair dye composition that has improved dyeability and reduced damage to hair compared to current products. In addition, hair dyes adsorbed on the hair are less dangerous and can be used easily compared to the above-mentioned oxidation type hair dyes, but on the other hand, the hair dyeing power is slightly reduced and discoloration due to hair washing (use of shampoo) In addition, the hair dye was short-lasting and temporary.
[0005]
[Means for solving problems]
Phosphate ester and aliphatic alcohol are known substances, but as a result of various researches, a mixture of two specific phosphate esters and an aliphatic alcohol is added in an amount of 0.01 to 30.0% by weight. Thus, in addition to improving dyeability and reducing damage to the scalp and hair, the odor of ammonia can be reduced. It has been found that it is possible to improve dyeability and prevent shampoo fading for hair dyes, and the present invention has been completed.
[0006]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the configuration of the present invention will be described in detail.
[0007]
The specific phosphate ester blended in the present invention is a phosphate ester represented by the following general formula (1) or (2). The substituents R1 and R2 in the formula are hydrocarbon groups having 8 to 24 carbon atoms, preferably 8 to 18 carbon atoms, and particularly preferably linear alkyl groups having 8 to 18 carbon atoms. The substituent represented by R3 in the formula of the phosphate ester represented by the general formula (2) is a hydrocarbon group having 8 to 24 carbon atoms, preferably 8 to 18 carbon atoms, and particularly a straight chain having 8 to 18 carbon atoms. An alkyl group is preferred. n is an integer selected from 0 to 20, preferably n = 10 and n = 20. As the specific phosphate ester, dicetyl phosphate, monopolyoxyethylene cetyl ether phosphate, and the like are preferable. As the aliphatic alcohol, cetostearyl alcohol, cetyl alcohol and the like are preferable. In the composition of the present invention, two types of phosphate ester having the above structure and an aliphatic alcohol are blended. When this mixture is represented by a trade name, it is CRODAFOS CES, CRODAFOS CS-20 ACID, etc. manufactured by CRODA JAPAN.

EFFECT OF THE INVENTION By blending the mixture of the specific phosphate ester and aliphatic alcohol of the present invention, the oxidative hair dye reduces hair damage and reduces irritation to the scalp. In addition, ammonia odor during treatment is reduced. Since dyeability is improved, the dye concentration can be lowered. As a result, it is possible to reduce the allergic reaction to the hair dye. Hair dyes have the effect of improving dyeability and preventing shampoo fading.
