Description
【0001】
【発明の属する技術分野】
本発明は、ボディー用、洗顔用、手洗い用、毛髪用等の用途を有する洗浄剤組成物に関する。
【0002】
【従来の技術】
これまで一般的に洗浄剤は、高級脂肪酸のアルカリ金属塩またはアルカリ土類金属塩を主成分としており、組成物としてアルカリ性を呈するものが主体であった。なぜならば、昔から日本人は、洗浄中の泡立ちと、洗い上がり後のさっぱり感を好む傾向が強かったからである。しかも、海外に比べて生活用水が軟水であり、脂肪酸のアルカリ金属塩を主成分とするアルカリ性を呈する洗浄剤を使用しても、脂肪酸のカルシウム塩やマグネシウム塩等の石鹸カスを生じないため、それほど不便さを感じていなかった。
【0003】
しかし、近年食生活の変化や生活習慣の変化、大気汚染、環境汚染等による生活環境の悪化等に伴い、皮膚の様々な刺激に対する感受性が強く、皮膚疾患に羅患しやすい人が増加しており、実際にアトピー性皮膚炎や乾皮症皮膚炎等により著しく皮膚への刺激に弱い人および症状こそ発症していないが、その危険因子を持っている予備軍といえる人が増加している。そのような人たちが従来のアルカリ性を呈する洗浄剤を使用すると、皮膚疾患の発症や症状悪化を招くなど、さまざまな障害を惹起するケースもあり、皮膚刺激性の低い安全性の高い洗浄剤の開発が望まれていた。
【0004】
そのような社会的な要求もあり、これまでの皮膚刺激性の高い高級脂肪酸のアルカリ金属塩またはアルカリ土類金属塩を主成分とする洗浄剤に代えて、安全性の高い中性から弱酸性の洗浄剤が開発されており、具体的にはアミノ酸系界面活性剤等を組み合わせた弱酸性洗浄剤(特許公開昭和53年第132007号、特許公開昭和63年第2962号等)等が発明されている。しかし、これらのアミノ酸系界面活性剤等を組み合わせた洗浄剤では、低刺激性ではあるものの、単独では必ずしも充分な起泡力、洗浄力を発揮しえないこと、溶解性が悪いこと等の欠点を有していた。従って、それらアミノ酸系界面活性剤等を組み合わせた中性から弱酸性を呈する洗浄剤の欠点を補うための洗浄剤の研究もなされ、アミノ酸系界面活性剤の変わりにアニオン性界面活性剤とグリセリルエーテルを含有する洗浄剤(特許公開2001年第107097号)、N−アシルアミノ酸アルカリ塩と、マルチトールヒドロキシ脂肪族エーテルと、水と、有機酸とを含有する皮膚洗浄料(特許公開2000年第204035号)、N−アシルアミノ酸アルカリ塩と、ベタイン系両性界面活性剤と、水と、有機酸とを含有する皮膚洗浄料(特許公開2001年第19632号)等が発明されていた。
【0005】
しかしこれらは洗浄剤の安全性と、洗浄効果、泡立ち等の全てを必ずしも満たすものではなかった。またアミノ酸系界面活性剤を主成分とする弱酸性洗浄剤組成物としてエチレン脂肪酸アミド硫酸エステル塩とN-アシルグルタミン酸塩を配合した洗浄料(特許公開平成2年第235999号)、N−長鎖アシルグルタミン酸塩化合物とコラーゲン化合物とを含有することを特徴とする固形洗剤(特許公開平成6年第57289号)等が発明されているが、必ずしも洗浄効果、泡立ち等が不十分であったり、組成物の安定性が悪く透明な容器に充填して保存すると直射日光により組成物が黄変してしまい商品価値を損なうため包装材料の選択に幅が狭くなるという欠点を有しているケースも存在した。
【0006】
このアミノ酸系界面活性剤を組み合わせた弱酸性洗浄剤の問題点である泡立ちの悪さや洗い上がり後の使用感、組成物の安定性の悪さ等の問題の全てを解決するアミノ酸系界面活性剤を主成分とする弱酸性洗浄剤は従来見出されていなかった。
【0007】
【発明が解決しようとする課題】
本発明は、洗浄剤組成物に関し、更に詳細にはアミノ酸系界面活性剤を主成分とする弱酸性洗浄剤であるにもかかわらず適度な起泡性、洗浄力、泡質が良好で使用性がよく、しかも洗い上がり後の肌にぬめり感等を残さず、洗浄時の使用感および泡立ちを向上させるとともに組成物の直射日光による黄変を防止した皮膚用あるいは毛髪用の洗浄料組成物に関するものである。
【0008】
【課題を解決するための手段】
かかる実情において本発明者らは、前述の課題を解決すべく鋭意研究を行なった結果、(A)アミノ酸系界面活性剤を主成分とし、より好ましくは実質的に脂肪酸石鹸(脂肪酸のアルカリ金属塩)を配合しない弱酸性洗浄剤において、(B)サポニン含有植物抽出物と(C)レシチンおよび/またはリゾレシチンを配合することにより、安全性を損なうことなく、泡立ちの改善と、泡立ち効果の持続、保湿性の改善といった洗浄時の感触を改善するとともに組成物の安定性が増し直射日光による組成物の変色を防止することを見出し、本発明を完成させた。
【0009】
(1) アミノ酸系界面活性剤を主洗浄成分とする弱酸性洗浄剤組成物であって、(A)アミノ酸系界面活性剤の1種又は2種以上と、組成物全体に対し、(B)サポニン含有サボンソウ抽出物を0.001〜10.0%および(C)レシチンおよび/またはリゾレシチンを0.001〜6.0%配合することを特徴とする弱酸性洗浄剤組成物。
(2) (A)アミノ酸系界面活性剤が、N−脂肪酸アシルアミノ酸のアルカリ金属塩またはトリエタノールアミン塩であることを特徴とする(1)に記載の弱酸性洗浄剤組成物。
(3) アミノ酸系界面活性剤を主洗浄成分とする弱酸性洗浄剤組成物に、組成物全体に対し、サポニン含有サボンソウ抽出物を0.001〜10.0%、および、レシチンおよび/またはリゾレシチンを0.001〜6.0%配合する弱酸性洗浄剤組成物の変色防止方法。
【0010】
【発明の実施の形態】
本発明の洗浄剤組成物は、粉末状、顆粒状、固形状、液状、クリーム状、ペースト状であってもよく、形状には左右されないが、特に液状あるいはクリーム状が好ましい。
【0011】
ここで、本発明における弱酸性洗浄剤組成物について定義しておくと、例えば液体洗浄剤の場合にはそのままの製剤のpH、固形洗浄剤の場合には、水で10〜200倍に希釈した時の水溶液のpH、クリーム状洗浄剤の場合には、水で10〜200倍に希釈した時の水溶液のpHのそれぞれが、4.0〜6.5である洗浄剤組成物をいい、洗浄効果および洗いあがりの感触面等からそのpHは5.0〜6.3であることがより好ましい。
【0012】

前記アミノ酸系界面活性剤の配合割合は、固形洗浄剤の場合、該組成物に対して、通常30〜95%、好ましくは60〜90%である。固形洗浄剤組成物における前記配合割合がこの範囲を下回ると、アミノ酸系界面活性剤のもつ洗浄力及びさっぱり感が不足し、この範囲を超えると脆くなり、成形が困難となったり、使用時の水への溶解性が低下する。
【0017】
また、液状洗浄剤組成物の場合、前記アミノ酸系界面活性剤の配合割合は、該組成物に対して、通常1〜35%、好ましくは4〜30%である。液状洗浄剤組成物における前記配合割合がこの範囲を下回るとアミノ酸系界面活性剤のもつ洗浄力及びさっぱり感が不足し、この範囲を超えると粘性が上がり低温安定性が著しく悪化する。
【0018】
さらに、クリーム状洗浄剤組成物の場合、前記アミノ酸系界面活性剤の配合割合は、該組成物に対して、通常10〜60%、好ましくは15〜50%である。クリーム状洗浄剤組成物における前記配合割合がこの範囲を下回るとアミノ酸系界面活性剤のもつ洗浄力及びさっぱり感が不足し、この範囲を超えるとクリーム状にならず、安定性が著しく悪化する。

本発明で配合するサポニン含有植物抽出物は、水、アルコール類、有機溶媒およびそれらを組み合わせた混合物でそれら植物を抽出したものであれば何でもよいが、皮膚刺激性等の観点から水またはエタノール、多価アルコールまたはその混合物で抽出したものが特に好ましく、さらに抽出物の濃縮エキスや乾燥した粉末を配合しても良い。

本発明で配合する(C)レシチンまたはリゾレシチンは、市販のものを用いればよいが、レシチンまたはリゾレシチンを含有する植物である大豆等の抽出物を配合しても良い。

本発明の効果を奏するレシチン及び/またはリゾレシチンの配合量は、組成物全体に対し0.001〜6.0%配合することが好ましく、さらに0.01〜3.0%配合することがより好ましい。レシチン及び/またはリゾレシチンの配合量がこの範囲を下回ると充分な効果を奏せず、この範囲を超えると逆に組成物の安定性が悪くなる。
【0023】
本発明の洗浄剤組成物に配合するアミノ酸系界面活性剤以外の界面活性成分は、本発明品が弱酸性であり皮膚に低刺激な洗浄剤であることから、アルカリ石鹸類は実質的に配合しない。

BACKGROUND OF THE INVENTION
The present invention relates to a cleaning composition having uses for body, face washing, hand washing, hair and the like.
[0002]
[Prior art]
So far, generally, the detergent has been mainly composed of an alkali metal salt or alkaline earth metal salt of a higher fatty acid and exhibiting alkalinity as a composition. This is because Japanese people have long had a tendency to like foaming during washing and a refreshing feeling after washing. Moreover, because domestic water is soft water compared to overseas, even when using an alkaline cleaning agent mainly composed of an alkali metal salt of a fatty acid, soap scum such as calcium salt or magnesium salt of fatty acid is not generated. I didn't feel so inconvenient.

However, with recent changes in dietary habits and lifestyle habits, deterioration of living environment due to air pollution, environmental pollution, etc., the number of people who are highly susceptible to various skin irritation and are susceptible to skin diseases has increased. In fact, there are an increasing number of people who are extremely vulnerable to skin irritation due to atopic dermatitis, xeroderma dermatitis, etc. . If such people use a conventional alkaline detergent, it may cause various disorders such as the onset of skin diseases and worsening of symptoms, and a highly safe detergent with low skin irritation. Development was desired.
[0004]
In response to such social demands, instead of detergents based on alkali metal salts or alkaline earth metal salts of higher fatty acids with high skin irritation so far, highly safe neutral to slightly acidic In particular, a weakly acidic detergent (patent publication No. 132007, patent publication No. 2962, etc.) etc. that was combined with an amino acid surfactant was invented. ing. However, the detergents combined with these amino acid-based surfactants, etc., have low irritation properties, but are not necessarily capable of exerting sufficient foaming power and cleaning power alone, and have disadvantages such as poor solubility. Had. Therefore, research on detergents to compensate for the disadvantages of neutral to weakly acidic detergents combining these amino acid surfactants has also been made. Instead of amino acid surfactants, anionic surfactants and glyceryl ethers have been studied. A skin cleansing agent (Patent Publication 2000 No. 204035) containing N-acylamino acid alkali salt, maltitol hydroxy aliphatic ether, water, and an organic acid. No.), an N-acylamino acid alkali salt, a betaine amphoteric surfactant, water, and an organic acid, a skin cleanser (Patent Publication No. 19632) was invented.
[0005]
However, these do not necessarily satisfy all of the safety of the cleaning agent, the cleaning effect, foaming and the like. Further, as a weakly acidic detergent composition mainly composed of an amino acid-based surfactant, a detergent comprising ethylene fatty acid amide sulfate and N-acyl glutamate (Patent Publication No. 235999), N-long chain A solid detergent (Patent Publication No. 57289) containing an acyl glutamate compound and a collagen compound has been invented. However, the cleaning effect, foaming, etc. are not always sufficient, or the composition There are cases in which the stability of the product is poor and when it is stored in a transparent container, the composition will turn yellow due to direct sunlight and the product value will be damaged, so the selection of packaging materials will be narrow. did.
