本発明は、アルカリ剤としてアルカノールアミンを含有し、アンモニアおよびアンモニウム塩を含有しない染毛剤または脱色剤組成物の使用時における不快臭抑制剤に関する。さらに詳しくは、アルカリ剤としてアルカノールアミンを含有し、アンモニアおよびアンモニウム塩を含有しない染毛剤または脱色剤組成物の使用時におけるアミン類の不快臭抑制剤に関する。 TECHNICAL FIELD The present invention relates to an unpleasant odor suppressant when using a hair dye or bleach composition containing an alkanolamine as an alkaline agent and not containing ammonia and an ammonium salt. More particularly, it relates to an unpleasant odor inhibitor for amines when using a hair dye or decolorant composition that contains an alkanolamine as an alkaline agent and does not contain ammonia or an ammonium salt.
近年のファッション意識の高まりから、手軽に髪の色を変化させることのできるヘアカラーリング剤は、男女問わず多くの人に受け入れられている。ヘアカラーリング剤には、永久染毛剤、半永久染毛料、脱色剤および一時着色料など、様々な種類があり、それぞれのニーズによって使用される。なかでも永久染毛剤および脱色剤は、染毛および脱色効果に優れ、この特性から現在多くの人に使用されているヘアカラーリング剤である。 BACKGROUND ART Hair coloring agents that can easily change the color of hair have been accepted by many people, regardless of gender, due to the recent increase in fashion awareness. There are various types of hair coloring agents, such as permanent hair dyes, semi-permanent hair dyes, bleaching agents, and temporary coloring agents, which are used according to their respective needs. Among them, permanent hair dyes and bleaching agents are excellent in hair dyeing and bleaching effects and are currently used by many people because of these properties.
ヘアカラーリング剤の永久染毛剤および脱色剤には、一般的にアルカリ剤を含有する第１剤と酸化剤を含有する第２剤で構成されており、第１剤に用いられる一般的なアルカリ剤として、アンモニアが使用されている。しかし、アンモニアは、強い刺激臭を有しており、使用時において刺激臭の不快感を伴う欠点があった。 Permanent hair dyes and bleaching agents for hair coloring agents generally consist of a first agent containing an alkaline agent and a second agent containing an oxidizing agent. Ammonia is used as an alkaline agent. However, ammonia has a strong irritating odor, and has the drawback of causing an unpleasant sensation during use.

表３および表４に示した不快臭抑制剤を含有した染毛剤組成物１ｇを、人毛毛束（株式会社ビューラックス、人毛黒髪１００％（１ｇ×１０ｃｍ））に塗布し、直ちに人毛毛束の表、裏に各２０回櫛を通して均一にする。 不快臭抑制剤を含有した染毛剤組成物を塗布した毛束をビーカー（ＩＷＡＫＩ、５００ｍｌビーカー、胴外径９０ｍｍ×高さ１２５ｍｍ）に入れ、ビーカー天面をデュラシール（ＤＳ４－５００）で密封し、１０分間放置して人毛毛束と反応させた後、デュラシールの上に粘着テープ（日東電工ＣＳシステム株式会社、布粘着テープＮｏ．７７０）を張り付けてデュラシールが裂けることを防いだうえで、ビーカー上部の中心部分に検知管の先端がビーカー上部から３ｃｍの高さとなるように差し込み、検知管式気体測定器のハンドルを操作して測定ガスを吸引し、アミン類の濃度を測定する。 [Test method for unpleasant odor of amines]
1 g of the hair dye composition containing the unpleasant odor inhibitors shown in Tables 3 and 4 was applied to a bundle of human hair (Beaulux Co., Ltd., 100% black human hair (1 g × 10 cm)), and immediately. Comb the front and back of the bundle 20 times each to make it uniform. A hair bundle coated with a hair dye composition containing an unpleasant odor inhibitor is placed in a beaker (IWAKI, 500 ml beaker, body outer diameter 90 mm x height 125 mm), and the top surface of the beaker is sealed with DuraSeal (DS4-500). After leaving it for 10 minutes to react with the human hair tress, an adhesive tape (Nitto Denko CS System Co., Ltd., cloth adhesive tape No. 770) was attached on the DuraSeal to prevent the DuraSeal from tearing. Then, insert the tip of the detector tube into the center of the top of the beaker so that the tip is 3 cm above the top of the beaker, operate the handle of the detector tube type gas measuring instrument to suck the measurement gas, and measure the concentration of amines. .
