Description
本発明は、泡質がクリーミィで弾力性を有し、皮膚刺激感が緩和で、しっとりとした肌感触が付与でき、さらに低温における安定性にも優れたフォーマー容器入り液体洗浄剤組成物に関する。 The present invention relates to a liquid detergent composition in a former container which has a foamy quality and elasticity, has a mild skin irritation feeling, can provide a moist skin feel, and has excellent stability at low temperatures.
皮膚用又は毛髪用洗浄剤は、通常泡立てて使用され、そうすることで皮膚又は毛髪を傷つけることなく洗浄できることが知られている。洗浄剤には、固形状、液状、泡沫状等の剤型があるが、これらのうち泡沫状の洗浄剤は、泡立てる必要が無く、しかも簡便にクリーミィな泡が得られることから、手洗い用、洗顔用、洗髪用等の種々の用途に広く用いられている。 It is known that skin or hair cleaning agents are usually used in a foamed manner, so that they can be cleaned without damaging the skin or hair. There are solid, liquid, foam and other dosage forms for cleaning agents, but among these, foamy cleaning agents do not need to be foamed, and can easily obtain creamy foam. It is widely used in various applications such as face washing and hair washing.
泡沫状の洗浄剤は、フォーマー容器からの吐出時に泡沫状にさせるタイプのものが一般的で、フォーマー容器としては、例えばスクイズフォーマーやポンプフォーマー等のノンエアゾール型の吐出容器が挙げられる。これらの容器に充填された洗浄剤組成物は、吐出時に容器の内部にある多孔質膜を通過する際に、空気と混合されて泡沫状となる。 The foam-type cleaning agent is generally of a type that is foamed when discharged from the former container, and examples of the former container include non-aerosol-type discharge containers such as squeeze foamers and pump foamers. When the detergent composition filled in these containers passes through the porous film inside the container at the time of discharge, it is mixed with air and becomes foamy.
泡沫状の洗浄剤では、洗浄剤組成物を多孔質膜に通過させる必要があるため、低温環境下で組成物がゲル化や固化を起こしたり、組成物中の成分が析出したりすると、多孔質膜が目詰まりを起こし、使用できなくなってしまう場合がある。 In the case of a foamy cleaning agent, it is necessary to pass the cleaning composition through the porous membrane. Therefore, if the composition gelates or solidifies in a low temperature environment or the components in the composition are precipitated, The membrane may become clogged and become unusable.
そこで、このような問題を改善するための洗浄剤組成物が提案されている。例えば、高級脂肪酸塩と特定の成分との組合せ(特許文献1、2参照)や、N−アシルアミノ酸系アニオン性界面活性剤と特定の成分との組合せ(特許文献3〜5参照)等が開示されている。 Therefore, a cleaning composition for improving such problems has been proposed. For example, a combination of a higher fatty acid salt and a specific component (see Patent Documents 1 and 2), a combination of an N-acylamino acid anionic surfactant and a specific component (see Patent Documents 3 to 5), etc. are disclosed. Has been.
しかし、これらの洗浄剤組成物では、低温環境下での安定性に加えて泡質、皮膚刺激感、肌感触等についても考慮はされてはいるが、十分な洗浄力や良好な泡質を得ようとすると皮膚刺激や肌感触が低下する傾向にあり、全てを満足するものはなかった。
従って、本発明の課題は、泡質、皮膚刺激感、感触及び安定性の全てにおいて十分に満足のいくフォーマー容器入り液体洗浄剤組成物を提供することにある。
However, in these detergent compositions, in addition to stability under low-temperature environments, foam quality, skin irritation, skin feel, etc. have been considered, but sufficient detergency and good foam quality are achieved. When trying to obtain, skin irritation and skin feel tended to decrease, and none of them satisfied all.
Accordingly, an object of the present invention is to provide a liquid cleaning composition in a former container that is sufficiently satisfactory in all of foam quality, skin irritation, touch and stability.
上記課題を解決するために鋭意検討を行った結果、界面活性剤と多価アルコールを含有するフォーマー容器入り液体洗浄剤組成物において、界面活性剤を特定の界面活性剤の組み合わせを含有する構成とすることにより、泡質がクリーミィで弾力性を有し、皮膚刺激感が緩和で、しっとりとした肌感触が得られ、低温における安定性にも優れるフォーマー容器入り液体洗浄剤が得られることを見出した。 As a result of diligent studies to solve the above problems, in the liquid detergent composition in a former container containing a surfactant and a polyhydric alcohol, the surfactant contains a combination of a specific surfactant and It has been found that a foam cleaning liquid cleaner with foam quality is creamy and elastic, the skin irritation feeling is relaxed, moist skin feel is obtained, and stability at low temperature is also obtained. It was.
すなわち、本発明は、(A)界面活性剤と(B)多価アルコールを含有するフォーマー容器入り液体洗浄剤組成物であって、(A)界面活性剤が、(a1)N−アシルグルタミン酸系アニオン性界面活性剤、(a2)下記一般式(1)で表されるベタイン型両性界面活性剤及び(a3)高級脂肪酸石鹸を含有することを特徴とする、フォーマー容器入り液体洗浄剤組成物を提供するものである。 That is, the present invention is a liquid detergent composition in a former container containing (A) a surfactant and (B) a polyhydric alcohol, wherein (A) the surfactant is (a1) an N-acylglutamic acid type A liquid detergent composition in a former container comprising an anionic surfactant, (a2) a betaine amphoteric surfactant represented by the following general formula (1), and (a3) a higher fatty acid soap. It is to provide.
(式中、R1は炭素数6〜20のアルキル基を示し、R2はメチル基、エチル基、又はヒドロキシエチル基を示し、R3はメチル基、エチル基、又は−CH2COOH基を示し、nは1〜3の整数を示す。) (In the formula, R 1 represents an alkyl group having 6 to 20 carbon atoms, R 2 represents a methyl group, an ethyl group, or a hydroxyethyl group, and R 3 represents a methyl group, an ethyl group, or a —CH 2 COOH group.
