Description
本発明は、起泡力、泡質および泡もちに優れ、すすぎ時および洗浄後の感触が良好であり、かつメイクや皮脂などの汚れを落とす効果（洗浄力）、保存安定性、および低温保存復元性に優れる、低刺激性の弱酸性泡状洗浄剤組成物に関する。 The present invention is excellent in foaming power, foam quality and foaminess, has a good feel during rinsing and after washing, and has an effect of removing dirt such as makeup and sebum (detergency), storage stability, and low-temperature storage. The present invention relates to a mild acid foam detergent composition having excellent resilience and low irritation.
従来、ボディシャンプー、洗顔料などの皮膚洗浄剤の主成分は高級脂肪酸アルカリ塩（せっけん）である。このせっけんは、洗浄後に独特のさっぱり感を有するだけでなく、生分解性も良好であり、環境に対しても優しい洗浄基剤として現在でも広く使用されている。 Conventionally, the main component of skin cleansing agents such as body shampoos and facial cleansers is higher fatty acid alkali salts (soap). This soap not only has a unique refreshing feeling after washing, but also has good biodegradability, and is still widely used as a washing base that is friendly to the environment.
ところで、皮膚洗浄剤に求められる機能としては、一般的に、洗浄力、泡の質感（泡質）、すすぎ性（すすぎ時の感触）、皮膚に対する低刺激性などが挙げられる。しかし、従来の皮膚洗浄剤は、手、タオルなどに適量を取り、水や湯を加えて、摩擦により泡立ててから洗浄を行うものであるため、温度や摩擦力によって、あるいは使用する水や湯の品質によって泡立ちおよび泡質が異なるという問題がある。さらに、洗浄時の過剰の摩擦により、皮膚に対する刺激性が強い場合がある。そして、洗浄後には、つっぱり感が残ることがあり、すすぎが不十分である場合には、残存する洗浄剤がアルカリ性を呈するため、皮膚に対する刺激性が問題となる。さらには色焼けを起こし易いなどの経時安定性も問題である。 By the way, the functions required of a skin cleanser generally include detergency, foam texture (foam quality), rinsing properties (feel during rinsing), low irritation to the skin, and the like. However, the conventional skin cleanser takes an appropriate amount on hands, towels, etc., adds water or hot water and foams it by friction, and then cleans it. There is a problem that foaming and foam quality differ depending on the quality of the foam. Furthermore, the skin may be highly irritating due to excessive friction during washing. And after washing | cleaning, a feeling of tension may remain, and when the rinse is inadequate, since the remaining washing | cleaning agent exhibits alkalinity, the irritation | stimulation with respect to skin becomes a problem. Furthermore, there is also a problem with the stability over time such that color burn is likely to occur.
そこで、近年、皮膚洗浄剤として、泡質の均一性、低刺激性などを考慮し、さらには１回の使用量を一定にすることが容易であるなどの利用性を考慮した泡状洗浄剤が提案されている。この泡状洗浄剤は、トリガー式、スクイズ式、エアゾール式、またはポンプ式などのフォーマー容器から吐出・発泡させて使用され、例えば、特許文献１〜３には、フォーマー容器に充填する洗浄剤組成物が提案されている。しかしながら、これらの洗浄剤組成物は、泡質および泡もちが十分でなく、また、少なからず、すすぎ時のぬめり感や洗浄後のつっぱり感を有するとともに、低温化での安定性やメイクなどの汚れに対しての洗浄力が充分でない。 Therefore, in recent years, as a skin cleanser, a foam cleanser considering the uniformity of foam quality, low irritation, etc., and taking into account the utility that it is easy to make a single use amount constant, etc. Has been proposed. This foam cleaning agent is used by being discharged and foamed from a trigger type, squeeze type, aerosol type, or pump type former container. For example, in Patent Documents 1 to 3, a cleaning agent composition filled in the former container is used. Things have been proposed. However, these detergent compositions do not have sufficient foam quality and foaminess, and have not only a small amount, but also a feeling of slimming during rinsing and a feeling of tension after washing, as well as stability at low temperatures and makeup. Insufficient detergency against dirt.
一方、低刺激性、すすぎ時のぬめり感の改善などを目的として「皮膚などに対してマイルド」といわれる低刺激性の合成界面活性剤を組み合わせ、かつｐＨを弱酸性に調整した低刺激性皮膚洗浄剤が提案されている。例えば、特許文献４にはアシルアルキルタウリン塩型陰イオン性界面活性剤およびアミドアミノ酸型両性界面活性剤、アミノ酢酸ベタイン型両性界面活性剤、アミドベタイン型両性界面活性剤を組み合わせた、起泡性に優れた低刺激性の洗浄剤組成物が開示されている。しかしながら、これらの洗浄剤組成物は、粘度が比較的高く、フォーマー容器から吐出しにくい。仮に、これらの洗浄剤組成物を水で希釈して粘度を低くした場合、界面活性剤濃度が低くなるため、良好な泡質や泡もち、および洗浄力が得られず、さらに低温下での安定性が悪くなる。 On the other hand, hypoallergenic skin, combined with a low-irritant synthetic surfactant called "mild against skin" for the purpose of improving the feeling of slimming during rinsing, etc., and adjusting the pH to slightly acidic Cleaning agents have been proposed. For example, Patent Document 4 discloses foaming properties obtained by combining an acylalkyltaurine salt type anionic surfactant and an amide amino acid type amphoteric surfactant, an aminoacetic acid betaine type amphoteric surfactant, and an amide betaine type amphoteric surfactant. A low-irritant detergent composition excellent in the above is disclosed. However, these detergent compositions have a relatively high viscosity and are difficult to eject from the former container. If these detergent compositions are diluted with water to reduce the viscosity, the surfactant concentration will be low, so good foam quality and foam will not be obtained, and detergency will not be obtained. Stability deteriorates.
そこで、泡質および泡もちに優れ、すすぎ時のぬめり感がなく、かつ洗浄力に優れた、低刺激性の泡状洗浄剤が求められている。
本発明の目的は、起泡力、泡質および泡もちに優れ、すすぎ時および洗浄後の感触が良好であり、かつメイクや皮脂などの汚れを落とす効果（洗浄力）、保存安定性、および低温保存復元性に優れる、低刺激性の弱酸性泡状洗浄剤組成物を提供することにある。 The object of the present invention is excellent in foaming power, foam quality and foaminess, has a good feeling during rinsing and after washing, and has an effect of removing dirt such as makeup and sebum (detergency), storage stability, and An object of the present invention is to provide a mildly acidic foam cleaning composition with low irritation and excellent low-temperature storage recovery.
本発明者らは、上記課題を解決するために鋭意検討を行った結果、特定の界面活性剤を特定の比率で組み合わせることによって、上記目的を達成できることを見出して本発明を完成するに至った。 As a result of intensive studies to solve the above problems, the present inventors have found that the above object can be achieved by combining specific surfactants at a specific ratio, and have completed the present invention. .

（実施例１〜５）
表１に示す各成分を表１に示す割合で混合し、該混合物のｐＨをクエン酸一水和物を含有する水溶液を用いて５．５に調整して洗浄剤組成物を得た（組成物１〜５）。得られた組成物１〜５を用いて、泡もち、泡質、すすぎ時の感触、洗浄後の感触、洗浄力、保存安定性、および低温保存復元性について、上記試験方法により評価した。結果を表１に示す。なお、組成物１および２、ならびに後述する組成物１〜１１に使用されるｅ成分の共重合体は、メタクリロイルオキシエチルホスホリルコリンとメタクリル酸ブチルとが８：２の質量比で構成されている。
(Examples 1-5)
Each component shown in Table 1 was mixed at a ratio shown in Table 1, and the pH of the mixture was adjusted to 5.5 using an aqueous solution containing citric acid monohydrate to obtain a cleaning composition (composition 1-5). Using the obtained compositions 1 to 5, the above test method evaluated foaminess, foam quality, feel at the time of rinsing, feel after washing, cleaning power, storage stability, and low-temperature storage restoration property. The results are shown in Table 1. In addition, the copolymer of e component used for composition 1 and 2 and the compositions 1-11 mentioned later is comprised by the mass ratio of methacryloyloxyethyl phosphorylcholine and butyl methacrylate of 8: 2.
（比較例１〜１１）
表２に示す各成分を表２に示す割合で混合し、該混合物のｐＨをクエン酸一水和物を含有する水溶液を用いて５．５に調整して洗浄剤組成物を得た（組成物６〜１６）。得られた組成物６〜１６を用いて、泡もち、泡質、すすぎ時の感触、洗浄後の感触、洗浄力、保存安定性、および低温保存復元性について、上記試験方法により評価した。結果を表２に示す。
(Comparative Examples 1-11)
Each component shown in Table 2 was mixed in the ratio shown in Table 2, and the pH of the mixture was adjusted to 5.5 using an aqueous solution containing citric acid monohydrate to obtain a cleaning composition (composition Things 6-16). Using the obtained compositions 6 to 16, the above test method evaluated foaminess, foam quality, feel at the time of rinsing, feel after washing, cleaning power, storage stability, and low-temperature storage restoration property. The results are shown in Table 2.
表１の結果から、実施例１〜５の洗浄剤組成物は、いずれも泡質、泡もちに優れ、すすぎ時および洗浄後の感触が良好であり、メイクなどの汚れを落とす効果に優れ、かつ保存安定性、低温保存復元性にも優れていた。特に組成物１〜３および組成物５は、ｅ成分を含有しており、ｅ成分を含有していない場合に比べて、泡質および洗浄後の感触が良好であった。なお、実施例１〜５の洗浄剤組成物は、使用の際、優れた起泡力を有していた。 From the results of Table 1, the detergent compositions of Examples 1 to 5 are all excellent in foam quality and foaminess, have a good feel during rinsing and after washing, and are excellent in the effect of removing dirt such as makeup, Moreover, it was excellent in storage stability and low-temperature storage / restorability. In particular, Compositions 1 to 3 and Composition 5 contained the e component, and the foam quality and feel after washing were better than when the e component was not contained. In addition, the cleaning composition of Examples 1-5 had the outstanding foaming power in the case of use.
他方、表２の結果から、比較例１〜１１の洗浄剤組成物は、本発明の範囲を満たさず、弱酸性泡状洗浄剤としての性能が十分得られないことがわかる。すなわち、比較例１では、ａ成分とｂ成分とｃ成分との合計量が高いため、使用性が悪く、水で希釈せずに使用できるという泡状洗浄剤の特性が失われていた。比較例２では、ａ成分とｂ成分とｃ成分との合計量が低いため、泡質、泡もち、および洗浄力の点で劣った。比較例３ではａ成分の含有量が高く、さらに（ａ＋ｃ）／ｂの値も高いため、保存安定性、低温保存復元性、すすぎ時および洗浄後の感触の点で劣った。比較例４ではａ成分が含有されていないため、泡質が悪かった。比較例５ではｂ成分の含有量が高く、さらに（ａ＋ｂ）／ｄの値も高いため、保存安定性が悪かった。さらに、洗浄剤が増粘し、フォーマー容器から吐出することが困難であり、泡質も悪かった。比較例６ではｂ成分が含有されていないため、すすぎ時および洗浄後の感触および洗浄力の点で劣った。比較例７ではｃ成分の含有量が高く、さらにｃ／ｄの値も高いため、すすぎ時および洗浄後の感触、ならびに洗浄力の点で劣った。比較例８ではｃ成分が含有されていないため、泡質の点で劣った。比較例９ではｄ成分の含有量が高く、さらにｃ／ｄの値も低いため、泡もちおよび泡質の点で劣った。比較例１０ではｄ成分の含有量が低いため、保存安定性および洗浄力の点で劣った。比較例１１ではｄ成分が含有されていないため、泡質、保存安定性、低温保存復元性、および洗浄力の点で劣った。 On the other hand, it can be seen from the results in Table 2 that the cleaning compositions of Comparative Examples 1 to 11 do not satisfy the scope of the present invention, and the performance as a weak acidic foam cleaning agent cannot be obtained sufficiently. That is, in Comparative Example 1, since the total amount of the a component, the b component, and the c component is high, the usability is poor and the characteristic of the foam cleaning agent that can be used without being diluted with water has been lost. In Comparative Example 2, since the total amount of the a component, the b component, and the c component was low, the foam quality, foaminess, and detergency were inferior. In Comparative Example 3, the content of component a was high, and the value of (a + c) / b was also high, so that the storage stability, low-temperature storage / restorability, the feeling at the time of rinsing and after washing were inferior. In Comparative Example 4, since the component a was not contained, the foam quality was poor. In Comparative Example 5, the content of the component b was high and the value of (a + b) / d was also high, so the storage stability was poor. Furthermore, the cleaning agent thickened, and it was difficult to discharge from the former container, and the foam quality was poor. In Comparative Example 6, since component b was not contained, the feel and cleaning power after rinsing and after cleaning were inferior. In Comparative Example 7, the content of component c was high, and the value of c / d was also high, so that the feeling during rinsing and after washing and the cleaning power were inferior. In comparative example 8, since c component was not contained, it was inferior in terms of foam quality. In Comparative Example 9, since the content of the d component was high and the value of c / d was low, it was inferior in terms of foaminess and foam quality. In Comparative Example 10, since the content of the d component was low, the storage stability and the detergency were inferior. Since the d component was not contained in the comparative example 11, it was inferior in terms of foam quality, storage stability, low-temperature storage restoration property, and detergency.
本発明によれば、起泡力、泡質および泡もちに優れ、すすぎ時および洗浄後の感触が良好であり、かつメイクや皮脂などの汚れを落とす効果（洗浄力）、保存安定性、および低温保存復元性に優れる、低刺激性の弱酸性泡状洗浄剤組成物が提供される。 According to the present invention, the foaming power, foam quality and foaminess are excellent, the feeling during rinsing and after washing is good, and the effect of removing dirt such as makeup and sebum (detergency), storage stability, and Provided is a mild acid foam detergent composition having low irritation and excellent low-temperature storage / restorability.
