Description
本発明は、酸性染料や酸化染料を含有する染毛剤を使用して毛髪を染色したときに、少なくとも毛髪の生え際付近の頭皮の他、手や肌等に付着した皮膚染着の汚れを除去するための染着除去剤組成物、およびこうした染着除去剤組成物を用いた染着除去方法に関するものである。 The present invention removes at least the scalp in the vicinity of the hairline, as well as skin stains attached to the hands and skin, when hair is dyed using a hair dye containing an acid dye or an oxidative dye. The present invention relates to a dyeing / removing agent composition and a dyeing / removing method using such a dyeing / removing agent composition.
毛髪を染色するには、酸性染料や酸化染料を含有する染毛剤が使用されるが、これらを使用したときに、少なくとも毛髪の生え際付近の頭皮の他、手や肌等に皮膚染着の汚れが付着することがある。こうしたことから、毛髪以外の箇所に付着した皮膚染着の汚れを取り除くための除去剤(以下、「染着除去剤」と呼ぶ)が必要となる。このような染着除去剤としては、これまで様々なものが提案されている。 Hair dyes containing acid dyes or oxidative dyes are used to dye hair, but when these are used, at least the scalp near the hairline, as well as skin dyeing on the hands and skin. Dirt may adhere. For this reason, a remover (hereinafter referred to as “dye remover”) for removing stains on the skin dye attached to portions other than the hair is required. Various types of dyeing removal agents have been proposed so far.
例えば、特許文献1には、(A)尿素および/またはチオ尿素、および(B)亜硫酸塩および/またはアルカリ成分を配合した染着除去剤が提案されている。この染着除去剤は、剤型が液状のものを想定したものであり、従来の染着除去剤は液状のものがほとんどである。 For example, Patent Document 1 proposes a dyeing / removing agent containing (A) urea and / or thiourea, and (B) sulfite and / or an alkali component. This dyeing removal agent assumes that the dosage form is liquid, and most conventional dyeing removal agents are liquid.
このような液状の染着除去剤では、皮膚染着の汚れが付着した部分(染着部分)を処理するときには、染着除去剤を脱脂綿等に含ませてから染着部分を擦る方法が一般的に採用されている。しかしながら、こうした方法では、脱脂綿等と皮膚との摩擦が生じることから皮膚刺激の面で問題がある。 In such a liquid dyeing remover, when treating a part of the skin dyed stain (dyed part), a method of rubbing the dyed part after adding the dye removing agent to absorbent cotton or the like is generally used. Has been adopted. However, such a method has a problem in terms of skin irritation because friction occurs between the absorbent cotton and the skin.
一方、特許文献2のように、剤型をゲル状やクリーム状とした染着除去剤も提案されている。この技術では、チオグリコール酸塩の如き還元性の脱色主剤に、染毛剤に含有されている金属を可溶化し得るキレート剤、および消炎剤を含有し、濃化剤によりゲルまたはクリーム状としたものである。しかしながら、こうした染着除去剤では、浸透性が低く染着除去を効果的に行えないという問題がある。 On the other hand, as in Patent Document 2, a dyeing / removing agent having a dosage form in a gel or cream form has also been proposed. In this technique, a reductive decoloring main agent such as thioglycolate, a chelating agent capable of solubilizing the metal contained in the hair dye, and an anti-inflammatory agent are contained. It is a thing. However, such a dyeing removal agent has a problem that it has low permeability and cannot effectively remove the dyeing.
本発明はこうした状況の下でなされたものであって、その目的は、各種染毛剤による皮膚染着の汚れを効果的に除去する性能を有し、しかも皮膚に対する刺激の少ない染着除去剤組成物、およびこうした染着除去剤組成物を用いて皮膚染着の汚れを効果的に除去する方法を提供することにある。 The present invention has been made under such circumstances, and the object thereof is a dyeing remover having the ability to effectively remove the stains of skin dyeing caused by various hair dyes and having little irritation to the skin. It is providing the composition and the method of removing effectively the stain | pollution | contamination of skin dyeing | staining by using such a dyeing removal agent composition.
上記目的を達成することのできた本発明の染着除去剤組成物とは、染毛剤を使用したときの皮膚染着の汚れを除去するために用いる染着除去剤組成物であって、(A)非イオン性界面活性剤、および(B)還元剤を夫々含有し、泡状に吐出して使用されるものである点に要旨を有する。 The dye removal agent composition of the present invention that has achieved the above object is a dye removal agent composition used for removing stains on skin dyeing when a hair dye is used, It has a gist in that it contains A) a nonionic surfactant and (B) a reducing agent, and is used by being discharged in the form of foam.
本発明の染着除去剤組成物には、必要によって、更に(C)浸透剤および(D)アルカリ剤を夫々含有させることも有効である。 It is also effective to further contain (C) a penetrating agent and (D) an alkali agent, if necessary, in the dyeing / removing agent composition of the present invention.
一方、上記目的を達成し得た本発明方法とは、上記のような染着除去剤組成物を、フォーマー容器から泡状に吐出しつつ皮膚染着の汚れを除去する点に要旨を有する。 On the other hand, the method of the present invention that has achieved the above object has a gist in that the stain of skin dyeing is removed while discharging the above-described dyeing removal composition from the former container in the form of foam.
本発明によれば、(A)非イオン性界面活性剤、および(B)還元剤を含有し、泡状に吐出して使用されるものとしたので、皮膚染着の汚れを効果的に除去することができると共に、染着除去の際の皮膚等に対する摩擦が少なく刺激も少ないものとなる。 According to the present invention, it contains (A) a nonionic surfactant and (B) a reducing agent, and is used by being discharged in the form of foam, so it effectively removes stains on the skin. In addition, there is little friction with respect to the skin or the like during dyeing and removal, and less irritation.
本発明者は、上記目的を達成するために様々な角度から検討を重ねた。そして、染毛後の乳化時(洗い落とし時)に、同時に染着除去剤組成物を使用すること、即ち、皮膚染着の汚れが存在する部分ができるだけ空気と触れ合わないようにすると染着除去が容易であることが判明した。 The inventor has studied from various angles in order to achieve the above object. And at the time of emulsification after dyeing (at the time of washing off), simultaneously using the dyeing remover composition, that is, if the part where the dirt of the skin dyeing exists is kept from contacting the air as much as possible, the dyeing removal It turned out to be easy.
通常、染毛剤の皮膚染着が気になるのは、白髪染めの場合がほとんどである。この白髪染めでは、根元部分をしっかりと染めるために、生え際部分の頭皮から染毛剤を塗布することが多い。そうすると、生え際付近の頭皮も毛髪と同様に染まることとなり、その汚れを除去しなければならなくなる。染毛剤の皮膚染着部分は空気と触れ合う時間が短いほど除去が容易であるという考え、染毛剤を洗い落とすと同時に染着除去剤を使用することが最も望ましいとの着想が得られた。 Usually, the hair dyeing is concerned about skin dyeing in most cases. In this gray hair dyeing, a hair dye is often applied from the scalp of the hairline part in order to dye the root part firmly. Then, the scalp near the hairline will be dyed in the same way as the hair, and the dirt must be removed. It was thought that the skin dyed portion of the hair dye is easier to remove as the time of contact with air is shorter, and the idea that it is most desirable to use the dye remover at the same time as washing off the hair dye.
これまで提案されている染着除去剤は、液状のものがほとんどである。液状の剤型では、染毛剤を洗い落とした後に脱脂綿等に含ませて擦り落とさなければならないため、洗い落としから染着除去剤の使用までに非常に時間がかかり、また手間がかかり、染着除去を効率よく行うことができない。その他、ゲル状やクリーム状のリムーバーも存在するが、染毛剤とのなじみが悪いため効率が良くない。これらに対して、泡状の剤型で染着除去剤を使用することで染毛剤を洗い落とすと同時に染着除去を行うことが、最も効率のよい方法であることを見出し、本発明を完成した。 Most of the dye removing agents proposed so far are liquid. In liquid dosage forms, the hair dye must be washed off and then wiped off with absorbent cotton etc., so it takes a very long time from washing off to using the dye remover, and it takes time and effort to remove the dye. Cannot be performed efficiently. In addition, there are gel-like and cream-like removers, but they are not efficient because they are poorly compatible with hair dyes. On the other hand, the present invention was completed by finding that the most efficient method is to wash off the hair dye at the same time by using the dye remover in a foamy dosage form and to remove the dye at the same time. did.
本発明の染着除去剤組成物は、少なくとも(A)非イオン性界面活性剤および(B)還元剤を含有するものである。これらの各成分は夫々、化粧料において従来から用いられてきたものであるが、これらの成分を含有するものを泡状の剤型で使用することによって、予想できない効果が得られたのである。各成分(A)および(B)による作用効果について説明する。 The dyeing / removing agent composition of the present invention contains at least (A) a nonionic surfactant and (B) a reducing agent. Each of these components has been conventionally used in cosmetics, but by using those containing these components in a foamy dosage form, an unexpected effect was obtained. The effect by each component (A) and (B) is demonstrated.
(A)非イオン性界面活性剤は、皮膚染着の汚れを洗浄すると共に、フォーマー容器により泡を生成する上で必要な成分である。このような非イオン性界面活性剤としては、ポリオキシエチレンアルキルエーテル、ポリオキシエチレン硬化ヒマシ油、アルキルグリセリルエーテル、脂肪酸モノエタノールアミド、ソルビタン脂肪酸エステル等が挙げられる。 (A) The nonionic surfactant is a component necessary for cleaning the stain of the skin dyeing and generating foam with the former container. Examples of such nonionic surfactants include polyoxyethylene alkyl ether, polyoxyethylene hydrogenated castor oil, alkyl glyceryl ether, fatty acid monoethanolamide, sorbitan fatty acid ester and the like.
(A)非イオン性界面活性剤の好ましい含有量は、染着除去剤組成物全体に占める割合で0.3〜10.0質量%程度である。(A)非イオン性界面活性剤の含有量が0.3質量%よりも少なくなると、染着除去効果が十分ではなくなる。また10.0質量%よりも過剰になっても、その効果が飽和し、それ以上の効果は期待できない。 (A) The preferable content of a nonionic surfactant is about 0.3-10.0 mass% in the ratio for the whole dyeing removal agent composition. (A) When the content of the nonionic surfactant is less than 0.3% by mass, the dyeing removal effect is not sufficient. Moreover, even if it becomes more than 10.0 mass%, the effect will be saturated and the effect beyond it cannot be anticipated.
(B)還元剤は、皮膚染着の汚れを除去する上で必要な成分である。こうした還元剤としては、チオグリコール酸、チオグリコール酸塩類、システイン等のメルカプト化合物類、亜硫酸塩類、チオ硫酸塩類、ラクトンチオール若しくはその他の還元性を有する化合物が挙げられる。その中でも亜硫酸塩類、亜硫酸水素塩類が好ましい。還元剤の好ましい含有量は、0.1〜4.0質量%である。(B)成分の配合量が0.1質量%よりも少なくなると、除去効果が十分でなくなる。また4.0質量%よりも過剰になっても、その効果が飽和し、それ以上の効果は期待できない。 (B) The reducing agent is a component necessary for removing dirt from skin dyeing. Examples of such a reducing agent include thioglycolic acid, thioglycolates, mercapto compounds such as cysteine, sulfites, thiosulfates, lactone thiols, and other reducing compounds. Of these, sulfites and bisulfites are preferred. The preferable content of the reducing agent is 0.1 to 4.0% by mass. When the blending amount of the component (B) is less than 0.1% by mass, the removal effect is not sufficient. Moreover, even if it exceeds 4.0 mass%, the effect will be saturated and the effect beyond it cannot be anticipated.
本発明の染着除去剤組成物には、必要によって、更に(C)浸透剤および(D)アルカリ剤を夫々含有させることも有効である。これらのうち、(C)浸透剤は、皮膚染着した染料を溶かし出す上で有効な成分であり、溶剤としての作用の他、皮膚への浸透を助ける作用も発揮する。こうした浸透剤としては、ベンジルアルコールやエタノール、プロパノール等のアルコール類、N−メチルピロリドン、プロピレングリコール、プロピレンカーボネート、尿素等が挙げられる。その中でも、エタノール、N−メチルピロリドン、ベンジルアルコールが好ましい。浸透剤の好ましい含有量は、1.0〜7.0質量%程度である。1.0質量%よりも少ないと染着除去効果が弱くなり、7.0質量%よりも多くなってもそれ以上の効果は期待できない。 It is also effective to further contain (C) a penetrating agent and (D) an alkali agent, if necessary, in the dyeing / removing agent composition of the present invention. Among these, (C) penetrating agent is an effective component for dissolving the dye dyed on the skin, and exerts an effect of assisting penetration into the skin in addition to the action as a solvent. Examples of such penetrants include alcohols such as benzyl alcohol, ethanol, and propanol, N-methylpyrrolidone, propylene glycol, propylene carbonate, urea, and the like. Of these, ethanol, N-methylpyrrolidone, and benzyl alcohol are preferable. A preferable content of the penetrant is about 1.0 to 7.0% by mass. If the amount is less than 1.0% by mass, the dyeing removal effect becomes weak, and even if the amount exceeds 7.0% by mass, no further effect can be expected.
(D)アルカリ剤は、皮膚染着の汚れを除去する上で有効な成分である。こうしたアルカリ剤としては、アンモニア水やモノエタノールアミン、トリエタノールアミン等のアルカノールアミン類を示す有機アミン類、水酸化ナトリウム等の無機アルカリ剤が挙げられる。その中でも、モノエタノールアミン、トリエタノールアミンが好ましい。アルカリ剤の好ましい含有量は、0.5〜3.0質量%程度である。0.5質量%よりも少なくなると染着除去効果が弱くなり、3.0質量%よりも多くなってもそれ以上の効果は期待できず、却って皮膚への刺激の原因となるので好ましくない。 (D) The alkaline agent is an effective component for removing stains from skin dyeing. Examples of such alkali agents include organic amines showing alkanolamines such as aqueous ammonia, monoethanolamine, and triethanolamine, and inorganic alkali agents such as sodium hydroxide. Among these, monoethanolamine and triethanolamine are preferable. The preferable content of the alkali agent is about 0.5 to 3.0% by mass. If the amount is less than 0.5% by mass, the effect of removing the dyeing is weakened, and if it exceeds 3.0% by mass, no further effect can be expected, and this is undesirable because it causes irritation to the skin.
本発明の染着除去剤組成物は、その剤型が泡状であることも特徴の一つとするものであり、泡状に吐出するためにはフォーマー容器が用いられる。このフォーマー容器は、ノンエアゾール型の容器であって、染着除去剤組成物を空気と混合し泡状に吐出させるために使用する。ノンエアゾール型の容器は再利用が可能であり安価であることから容易に取り扱うことが可能である。 The dyeing / removing agent composition of the present invention is also characterized in that the dosage form is foamy, and a foamer container is used for discharging in foamy form. This former container is a non-aerosol type container, and is used for mixing the dyeing removal agent composition with air and discharging it in the form of foam. Non-aerosol type containers can be reused and can be easily handled because they are inexpensive.
フォーマー容器としては、ポンプフォーマー容器、スクイズフォーマー容器等、ノンエアゾール型の容器で泡吐出機能を有するものであればいずれの容器を用いることもできる。皮膚の上に一定時間泡状であることが効果的であるため、フォーマー容器としては泡持ちの点から特にポンプフォーマーが好ましい。 As the former container, any container can be used as long as it is a non-aerosol type container having a foam discharge function, such as a pump former container or a squeeze foamer container. Since it is effective to be foamed on the skin for a certain time, a pump former is particularly preferable as the former container from the viewpoint of foam retention.
