Description

本発明は、洗浄料組成物に関する。 The present invention relates to a cleaning composition.

従来より、洗浄料として、種々の商品が開発されており、特に高級脂肪酸塩を基剤とするものは、洗浄力に優れ、泡立ちが良く、さっぱりとした感触があるため、洗顔料や全身洗浄料等に用いられている。しかし、その強力な洗浄力により、皮膚に必要な皮脂等まで落としてしまい、洗浄後に肌がかさつき、つっぱるといった問題が生じている。 Conventionally, various products have been developed as cleaning agents, and in particular, those based on higher fatty acid salts have excellent detergency, good foaming, and a refreshing feel, so they are used for washing pigments and whole body cleaning. It is used for fees. However, due to its strong detergency, even sebum and the like necessary for the skin are removed, causing problems such as the skin becoming dry and taut after cleaning.

洗浄後の肌のかさつきや、つっぱり感の改善のために、ジグリセリンのポリオキシプロピレン付加物と併用した例(特許文献1)、植物エキスと併用した例(特許文献2)があるが、いずれも効果が不十分で、問題を解決するには、至っていない。 In order to improve the dryness and tightness of the skin after washing, there are cases in which it is used in combination with a polyoxypropylene adduct of diglycerin (Patent Document 1) and in combination with a plant extract (Patent Document 2). However, the effect is insufficient and the problem has not been solved yet.

本発明は、脂肪酸塩を基剤とするにもかかわらず、泡質が良好で、保湿感を有する洗浄料組成物を提供することを課題とする。 An object of the present invention is to provide a cleaning composition having a good foam quality and a moisturizing sensation despite using a fatty acid salt as a base.

本発明は、下記の(A)〜(C)を含有する洗浄料組成物を提供する。
(A)高級脂肪酸塩
(B)メタクリル酸とエチルアクリレートとの架橋コポリマーのエマルション
(C)グリセリルグルコシド
The present invention provides a cleaning composition containing the following (A) to (C).
(A) Higher fatty acid salt (B) Emulsion of crosslinked copolymer of methacrylic acid and ethyl acrylate (C) Glyceryl glucoside

本発明の洗浄料組成物は、泡立ち、洗浄力、泡質が良好で、保湿感を有しながらもさっぱり感を有するという効果を発揮する。 The cleaning agent composition of the present invention has good foaming, detergency, and foam quality, and exhibits the effects of having a moisturizing feeling and a refreshing feeling.

以下本発明を実施するための形態を説明する。 Hereinafter, embodiments for carrying out the present invention will be described.

本発明で用いる高級脂肪酸塩を構成する高級脂肪酸としては、飽和若しくは不飽和のいずれであってもよく、炭素数8〜24、特に10〜22のものが好ましい。これらの脂肪酸の中でも直鎖飽和脂肪酸を用いることが、好ましい。好ましいものの具体例としては、ラウリン酸、ミリスチン酸、パルミチン酸、ステアリン酸、ヤシ油脂肪酸、還元ヤシ油脂肪酸、パーム核脂肪酸などが挙げられる。これらの脂肪酸の中でも、泡立ち、安全性、安定性の面から、ラウリン酸、ミリスチン酸、パルミチン酸、ステアリン酸から選択される1種又は2種以上を含有することが好ましく、特にラウリン酸とミリスチン酸とパルミチン酸の3種を用いることが好ましい。これらの高級脂肪酸と塩を形成するアルカリ剤としては、ナトリウム、カリウムなどのアルカリ金属塩、アンモニウム塩、モノエタノールアミン、ジエタノールアミン、トリエタノールアミン、2−アミノ−2−メチルプロパノール、2−アミノ−2−メチルプロパンジオールなどのアルカノールアミン塩、リジン、アルギニンなどの塩基性アミノ酸塩等が挙げられる。これらのうち、特にカリウム、アルギニンが好ましい。 The higher fatty acid constituting the higher fatty acid salt used in the present invention may be saturated or unsaturated, and has 8 to 24 carbon atoms, particularly preferably 10 to 22 carbon atoms. Among these fatty acids, it is preferable to use linear saturated fatty acids. Specific examples of preferable ones include lauric acid, myristic acid, palmitic acid, stearic acid, coconut oil fatty acid, reduced coconut oil fatty acid, palm kernel fatty acid and the like. Among these fatty acids, it is preferable to contain one or more selected from lauric acid, myristic acid, palmitic acid, and stearic acid from the viewpoint of foaming, safety, and stability, and particularly lauric acid and myristic acid. It is preferable to use three kinds of acid and palmitic acid. Examples of the alkaline agent forming a salt with these higher fatty acids include alkali metal salts such as sodium and potassium, ammonium salts, monoethanolamine, diethanolamine, triethanolamine, 2-amino-2-methylpropanol, and 2-amino-2. − Examples include alkanolamine salts such as methylpropanediol and basic amino acid salts such as lysine and arginine. Of these, potassium and arginine are particularly preferable.

また、これらの高級脂肪酸塩は、必ずしも脂肪酸塩として洗浄料組成物に配合する必要はなく、上記高級脂肪酸と塩基とをそれぞれ別個に添加し、組成物中で脂肪酸塩を形成させてもよい。 Further, these higher fatty acid salts do not necessarily have to be added to the cleaning composition as fatty acid salts, and the higher fatty acids and bases may be added separately to form fatty acid salts in the composition.

高級脂肪酸塩の配合量は、15〜25質量%が好ましい。15質量%未満の配合では十分な洗浄力が得られない場合がある。25質量%を超えて配合すると、結晶の析出や、液状の形態を保てなくなる場合がある。 The blending amount of the higher fatty acid salt is preferably 15 to 25% by mass. Sufficient detergency may not be obtained if the composition is less than 15% by mass. If it is blended in excess of 25% by mass, crystals may precipitate or the liquid form may not be maintained.

本発明で用いるメタクリル酸とエチルアクリレートとの架橋コポリマーのエマルション(アクリレーツコポリマーエマルションと略す場合があります。)は、アルカリで膨潤する水性分散体であり、純分30%のポリマーのエマルションである。かかるアクリレーツコポリマーエマルションとしては、カーボポールアクアSFー1(ノベオン社製)が例示される。 The emulsion of a crosslinked copolymer of methacrylic acid and ethyl acrylate used in the present invention (sometimes abbreviated as acrylates copolymer emulsion) is an aqueous dispersion that swells with alkali and is an emulsion of a polymer having a pure content of 30%. Examples of such an Acrylate copolymer emulsion include Carbopol Aqua SF-1 (manufactured by Noveon Co., Ltd.).

アクリレーツコポリマーエマルションの配合量は、他の成分の種類、量、pH等により変動されるべきものであり、所望の粘稠性が得られれば、特に限定されない。架橋コポリマー純分として0.05〜1.0質量%程度配合することが好ましい。0.05質量%未満の配合では保湿効果が得られない場合がある。1.0質量%を超えて配合すると、洗い流し後のさっぱり感が得られない場合がある。 The blending amount of the Acrylate copolymer emulsion should be varied depending on the type, amount, pH and the like of other components, and is not particularly limited as long as the desired consistency can be obtained. It is preferable to add about 0.05 to 1.0% by mass as the pure content of the crosslinked copolymer. A moisturizing effect may not be obtained if the composition is less than 0.05% by mass. If it is blended in excess of 1.0% by mass, a refreshing feeling after rinsing may not be obtained.

本発明で用いるグリセリルグルコシドは、洗浄料組成物に配合し得るものであれば製造方法は、合成、微生物による発酵法等を問わない。グリセリルグルコシドは、0.05〜5質量%、好ましくは0.1〜3質量%配合する。0.05質量%未満の配合では、保湿感が感じられない場合がある。5質量%を超えて配合すると、洗浄後のさっぱり感がなくなる場合がある。 As long as the glyceryl glucoside used in the present invention can be blended in the cleaning composition, the production method may be synthetic, fermentation with microorganisms, or the like. Glyceryl glucoside is blended in an amount of 0.05 to 5% by mass, preferably 0.1 to 3% by mass. If the composition is less than 0.05% by mass, a moisturizing feeling may not be felt. If it is blended in excess of 5% by mass, the refreshing feeling after washing may be lost.

本発明の洗浄料には、上述の成分の他に、通常の洗浄料分野等に用いられる任意成分を、本発明の効果を阻害しない程度に配合することができる。具体的には、精製水、油剤、界面活性剤、増粘剤、防腐剤、香料、紫外線吸収剤、保湿剤、抗酸化剤、抗炎症剤、抗菌剤等を挙げることができる。 In addition to the above-mentioned components, the cleaning agent of the present invention may contain arbitrary components used in the field of ordinary cleaning agents and the like to the extent that the effects of the present invention are not impaired. Specific examples thereof include purified water, oils, surfactants, thickeners, preservatives, fragrances, ultraviolet absorbers, moisturizers, antioxidants, anti-inflammatory agents, antibacterial agents and the like.

本発明の洗浄料は、常法により製造され、固形状、液状、乳液状、クリーム状、ペースト状、ジェル状、軟膏状等の剤型とすることができる。本発明の効果の点から、適度な粘性を有する液状の剤型をとることが好ましい。また本発明の洗浄料は、皮膚洗浄料、毛髪洗浄料として使用することができ、特に皮膚洗浄料として使用することが好ましい。 The cleaning agent of the present invention is produced by a conventional method and can be in a dosage form such as solid, liquid, milky, creamy, paste, gel or ointment. From the viewpoint of the effect of the present invention, it is preferable to take a liquid dosage form having an appropriate viscosity. Further, the cleansing agent of the present invention can be used as a skin cleansing agent and a hair cleansing agent, and is particularly preferably used as a skin cleansing agent.

以下に本発明を実施例を用いて説明するが、本発明の技術的範囲はこれによってなんら限定されるものではない。 Hereinafter, the present invention will be described with reference to examples, but the technical scope of the present invention is not limited thereto.
