Description
本発明は、エアゾール型皮膚洗浄料に関する。 The present invention relates to an aerosol type skin cleanser.
洗顔料、ボディシャンプー、ハンドソープに代表される皮膚洗浄料には、クリーミィな泡質が求められている。一般的に皮膚洗浄料は固形や液状であり、使用時に水を加え手やスポンジ等で泡立てて使用する必要があった。そのため簡便に泡立てるため、フォーマー容器に充填した皮膚洗浄料やエアゾール型の皮膚洗浄料の開発が進んでいる。例えば炭酸ガス、ポリグリセリンモノ脂肪酸エステル、グリセリンとを組み合わせたエアゾール型水性洗顔化粧料が報告されている（特許文献１参照）。 Skin cleansing agents such as facial cleansers, body shampoos and hand soaps are required to have a creamy foam quality. In general, skin cleansing materials are solid or liquid, and it is necessary to add water during use and foam with a hand or a sponge. For this reason, development of skin cleansers and aerosol-type skin cleansers filled in former containers for easy foaming is in progress. For example, an aerosol-type aqueous facial cleanser that combines carbon dioxide, polyglycerin monofatty acid ester, and glycerin has been reported (see Patent Document 1).
エアゾール型皮膚洗浄料においては、噴射剤としてプロパン、ブタン、ペンタン等の低級炭化水素の混合物である液化石油ガスが汎用されている。低分子の炭化水素を用いたエアゾール型皮膚洗浄料は、クリーミィな泡質の実現に適している一方、分子量が小さいため皮膚透過性の懸念があり、使用する人の肌タイプによっては刺激を感じることがあった。また、液化石油ガス以外の噴射剤として炭酸ガスの使用が知られているが、炭酸ガスには血行促進効果があり、多量の炭酸ガスを使用する場合に人によっては赤み、ほてり等の刺激に似た感触を受けることがあった。 In aerosol-type skin cleansers, liquefied petroleum gas, which is a mixture of lower hydrocarbons such as propane, butane and pentane, is widely used as a propellant. Aerosol-type skin cleanser using low molecular weight hydrocarbons is suitable for realizing creamy foam quality, but there is concern about skin permeability due to low molecular weight, and irritation may be felt depending on the skin type of the person using it There was a thing. Also, the use of carbon dioxide as a propellant other than liquefied petroleum gas is known, but carbon dioxide has an effect of promoting blood circulation, and when a large amount of carbon dioxide is used, it may cause irritation such as redness and hot flash depending on the person. I felt a similar feeling.
また、エアゾール型皮膚洗浄料には、洗浄の行為によるマッサージ効果が期待されている。それは単に物理的なマッサージ効果のみならず、泡状に吐出された皮膚洗浄料が肌と外気とを遮断し、皮膚温を上昇させ、皮膚の新陳代謝を促進したり、組成物中の有効成分の浸透を促すといった効果をも含む。泡が粗く保持性が不十分であると、肌に塗布しにくく、外気との遮断性が不十分となるため、エアゾール型皮膚洗浄料においては、泡の質・物性は重要視されている。このような問題に鑑み、従来様々な検討が行われている。例えばアシルアミノ酸塩と糖アルコールと水溶性多糖類を組み合わせるエアゾール型泡状マッサージ化粧料(特許文献２参照）、キサンタンガムとマルメロ種子抽出物を含有する泡沫形成化粧料（特許文献３参照）が報告されている。 In addition, aerosol-type skin cleansing materials are expected to have a massage effect due to the act of cleaning. It is not only a physical massage effect, but also a skin cleanser that is discharged in the form of foam blocks the skin and the outside air, raises the skin temperature, promotes the metabolism of the skin, and the active ingredients in the composition. Including the effect of promoting penetration. If the foam is rough and the retention is insufficient, it is difficult to apply to the skin and the barrier against the outside air is insufficient. Therefore, in the aerosol type skin cleanser, the quality and physical properties of the foam are regarded as important. In view of such a problem, various studies have been made in the past. For example, aerosol-type foam massage cosmetics (refer to Patent Document 2) combining acylamino acid salts, sugar alcohols and water-soluble polysaccharides, and foam-forming cosmetics (see Patent Document 3) containing xanthan gum and quince seed extract are reported. ing.
しかしながらエアゾール型皮膚洗浄剤において泡質、マッサージのしやすさ、感触を損なわずに刺激感を低減しようとする試みはほとんどなされていない。
従って、本発明の課題は、キメ細かくクリーミィな泡質で、肌をマッサージしやすく、洗いあがり後にはしっとりとした感触であるだけでなく、刺激感の少ないエアゾール型皮膚洗浄料を提供することにある。
However, few attempts have been made to reduce irritation without impairing foam quality, ease of massage, and feel in aerosol-type skin cleansers.
Accordingly, an object of the present invention is to provide an aerosol-type skin cleansing material that has a fine and creamy foam quality, is easy to massage the skin, has a moist feeling after washing, and has a less irritation feeling. .
本発明者は上記課題を解決するために鋭意研究を行なった結果、特定のアミノ酸系界面活性剤とアルキルアミノジカルボン酸型界面活性剤と多価アルコールに加えて、噴射剤として液化石油ガスと炭酸ガスを組み合せてエアゾール型皮膚洗浄料とすることにより、キメ細かくクリーミィな泡質で、肌をマッサージしやすく、洗いあがり後にはしっとりとした感触であり、さらに刺激感の少ないことを見出し、本発明を完成するに至った。 As a result of diligent research to solve the above problems, the present inventor has found that in addition to a specific amino acid surfactant, alkylaminodicarboxylic acid type surfactant and polyhydric alcohol, liquefied petroleum gas and carbonic acid as a propellant are used. By combining the gas into an aerosol-type skin cleanser, it was found that the skin texture was fine and creamy, easy to massage the skin, moist after touching, and less irritating. It came to be completed.

In addition, the compounding quantity of the composition of a following example and a comparative example is all the mass% (simply abbreviated as%).
・官能試験
１０名の被験者によってエアゾール型皮膚洗浄料の試料を頬の部位に塗布した。塗布後３０秒間マッサージを続け、ぬるま湯にて洗い流した。その後被験者本人が、泡のクリーミィさ、マッサージのしやすさ、洗いあがりのしっとり感、刺激感の無さについて、下記の評価基準に基いて官能評価し、評点の平均点により評価した。
-Sensory test A sample of aerosol type skin cleanser was applied to the cheek site by 10 subjects. Massage was continued for 30 seconds after application, and rinsed off with warm water. Thereafter, the subject himself / herself performed a sensory evaluation based on the following evaluation criteria regarding the creaminess of foam, ease of massage, moist feeling of washing, and lack of irritation, and evaluated by the average score.

実施例１〜３、比較例１〜５
表１に示した処方において、噴射剤以外の成分を加熱混合し、冷却後、耐圧容器に充填した。その後、噴射剤を加圧充填することによりエアゾール型皮膚洗浄料を調製した。次いで前記の官能試験を実施し、エアゾール型皮膚洗浄料を評価した。試験結果を表１に併せて示す。
Examples 1-3, Comparative Examples 1-5
In the prescription shown in Table 1, components other than the propellant were heated and mixed, and after cooling, filled in a pressure resistant container. Thereafter, an aerosol type skin cleanser was prepared by pressure filling with a propellant. Subsequently, the above-mentioned sensory test was carried out to evaluate the aerosol type skin cleanser. The test results are also shown in Table 1.
表１より明らかなように本発明の成分（Ａ）〜（Ｅ）を用いた実施例のエアゾール型皮膚洗浄料はいずれも優れた性能を有していた。一方、成分（Ａ）〜（Ｅ）のうちのいずれかを欠いた比較例では、泡のクリーミィさ、マッサージのしやすさ、しっとり感、刺激感の無さのいずれかの面で劣っており、本発明の目的を達成できなかった。 As is clear from Table 1, all of the aerosol type skin cleansing agents of Examples using the components (A) to (E) of the present invention had excellent performance. On the other hand, the comparative example lacking any of the components (A) to (E) is inferior in any aspect of foam creaminess, ease of massage, moist feeling, and lack of irritation. The object of the present invention could not be achieved.
