Description

アシルアミノ酸高配合組成物Acylamino acid high composition
 本発明は高濃度のアシルアミノ酸、アセトフェノン誘導体及び多価アルコールを含む抗菌性が高く保存性に優れた組成物及び該組成物を含む化粧料に関する。また前記組成物を添加することを特徴とする化粧料の防腐方法に関する。 The present invention relates to a composition having high antibacterial properties and high shelf-life containing a high concentration of acylamino acid, acetophenone derivative and polyhydric alcohol, and a cosmetic comprising the composition. The present invention also relates to a preservative method for cosmetics, which comprises adding the composition.
 近年の安全性志向の高まりによる防腐剤のイメージの低下から、市場では従来使用されてきたパラベンなどの各種防腐剤は消費者から敬遠される存在となっており、それらの防腐剤を配合せずに化粧品の防腐を行う技術が求められている。現在までに様々な素材の組み合わせを工夫して、化粧料の防腐を行う技術が数多く報告されている。しかし、それらに要求される条件は多く、例えば化粧料中における広いpHにおいての高い防腐効果や幅広い抗菌スペクトル、化粧品の各素材自体が広範囲の温度で長期にわたり優れた安定性を有すること、長期保存後でも化粧料中における性能が変化しないこと、さらに低刺激性であることや化粧料にとって重要である製品の感触に悪影響を与えないことなどが求められているが、すべての条件を満たす防腐に十分なものは報告されていない。 Due to the decline in the image of preservatives due to the recent increase in safety orientation, various preservatives such as parabens that have been used in the market have been avoided by consumers, and these preservatives have not been formulated. In addition, technology for preserving cosmetics is required. To date, many techniques for preserving cosmetics by devising combinations of various materials have been reported. However, there are many conditions required for them, for example, high antiseptic effect at a wide pH in cosmetics, wide antibacterial spectrum, each cosmetic material itself has excellent stability over a long period of time at a wide range of temperatures, and long-term storage There are demands for the performance in cosmetics not to change afterwards, and that it is hypoallergenic and does not adversely affect the feel of products important to cosmetics. Not enough has been reported.
 素材の組み合わせを工夫して化粧料の防腐を行う技術として、アセトフェノン誘導体と多価アルコール(特にジオール類)を用いて化粧料を防腐する方法が提案されている(特許文献1、2)。しかし、アセトフェノン誘導体と複数種の多価アルコールとの組み合わせにおいても、緑膿菌及びクロコウジカビに対して良好な相乗効果がみられるものではなかった。また、アセトフェノン誘導体は、乳化組成物中乳化滴を微細にし、乳化系を安定化させると共に、化粧料の官能性も向上させることが報告されているが、継時的な保存安定性試験はしておらず、且つ、着色安定性という観点でも議論されていなかった(特許文献1、2)。
 さらに、低分子ジオール類については使用感や処方への影響が大きいという問題があり、あまり配合量を増やすことは好ましくなく、場合によっては低刺激性の要件も満たさない場合がある。
As a technique for preserving cosmetics by devising combinations of materials, methods for preserving cosmetics using acetophenone derivatives and polyhydric alcohols (particularly diols) have been proposed (Patent Documents 1 and 2). However, even in the combination of an acetophenone derivative and a plurality of types of polyhydric alcohols, no good synergistic effect was observed against Pseudomonas aeruginosa and Aspergillus niger. In addition, acetophenone derivatives have been reported to make the emulsion droplets fine in the emulsion composition, stabilize the emulsion system, and improve the functionality of cosmetics. Further, it was not discussed from the viewpoint of coloring stability (Patent Documents 1 and 2).
Furthermore, there is a problem that low molecular diols have a great influence on the feeling of use and prescription, and it is not preferable to increase the blending amount so much, and in some cases, the requirement for low irritation may not be satisfied.
 一方、アシルアミノ酸は、低刺激で安全性の高い素材として知られている。なかでもアシルプロリン又はその塩は吸湿性と水分保持性に優れた保湿効果を示すこと、においが課題となる抗菌剤のにおいを抑えながら使用感に優れた化粧料を提供できることなどが報告されている(特許文献2及び3)。またアシルグリシン又はその塩は、低刺激性でかつぬめり感がない洗浄剤組成物として利用できること(特許文献4)、特にウンデシレノイルグリシンが抗ニキビ及び抗ふけ活性を有すること(特許文献5)、またオクタノイルグリシンは抗アクネ、制汗剤、消臭剤などとして使用され、抗菌効果を示すことが開示されているが化粧料においてきしみ感の原因となることも報告されている(特許文献6)。しかしアシルプロリンやアシルグリシンは、先述の化粧料の防腐を行う技術において、求められる条件を全て満たす素材としてはほど遠いのが現状であった。 On the other hand, acylamino acids are known as low-stimulation and high-safety materials. Among them, acylproline or a salt thereof has been reported to exhibit a moisturizing effect with excellent hygroscopicity and moisture retention, and to provide a cosmetic with an excellent feeling of use while suppressing the smell of antibacterial agents where odor is a problem. (Patent Documents 2 and 3). Acylglycine or a salt thereof can be used as a detergent composition with low irritation and no sliminess (Patent Document 4), and in particular, undecylenoylglycine has anti-acne and anti-dandruff activity (Patent Document 5). In addition, octanoylglycine is used as an anti-acne, antiperspirant, deodorant and the like, and has been disclosed to exhibit an antibacterial effect, but it has also been reported to cause squeaky feeling in cosmetics (Patent Document) 6). However, the present situation is that acylproline and acylglycine are far from being materials that satisfy all the required conditions in the above-described technology for preserving cosmetics.
 また化粧料中における各素材の比率の検討、さらにそれぞれの品質管理及び製造操作が煩雑であるため、組み合わせ効果の高い各素材を予め高濃度に含有し広範囲の温度でも長期保存安定性を保ちながら、容易に化粧料に配合できる液状の防腐用組成物が求められていた。 In addition, since the examination of the ratio of each material in cosmetics and the quality control and manufacturing operations are complicated, each material with a high combination effect is contained in a high concentration in advance, while maintaining long-term storage stability over a wide range of temperatures. There has been a demand for a liquid antiseptic composition that can be easily blended into cosmetics.

 本発明は、高濃度のアシルプロリン及び/又はアシルグリシンとアセトフェノン誘導体を含み、パラベンなどの防腐剤添加をしないで高い防腐効果を有し、十分な保存安定性を具備し、良好な使用感を実現可能な組成物を提供することである。 The present invention contains a high concentration of acylproline and / or acylglycine and an acetophenone derivative, has a high antiseptic effect without adding a preservative such as paraben, has sufficient storage stability, and has a good feeling of use. It is to provide a feasible composition.
 本発明者らは鋭意研究を重ねた結果、アセトフェノン誘導体を予め高濃度に含有する組成物は、広範囲の温度において長期間保存するには適さないことが判明したが、高濃度のアセトフェノン誘導体にアシルプロリン及び/又はアシルグリシン及び多価アルコールを組み合わせると、細菌や真菌、特にカビに対して広いpHにおいて高い防腐効果を有し、低温及び高温における長期保存後も析出、凍結、分離、濁り、着色、性能の変化などに問題のない、十分な保存安定性を具備し、低刺激性であってべたつきやきしみのない良好な使用感が得られることを見出し、本発明を完成した。 As a result of extensive research, the present inventors have found that a composition containing an acetophenone derivative at a high concentration in advance is not suitable for long-term storage at a wide range of temperatures. When combined with proline and / or acylglycine and polyhydric alcohol, it has a high antiseptic effect over a wide pH range against bacteria and fungi, especially mold, and precipitates, freezes, separates, becomes turbid, colored even after long-term storage at low and high temperatures The present invention has been completed by finding that it has a sufficient storage stability without causing a problem in performance change, has a low irritation, and has a good feeling of use without stickiness or creaking.

(技術分野)
 本発明は高濃度のアシルアミノ酸、ヒドロキサム酸誘導体及び多価アルコールを含む抗菌性が高く保存性に優れた組成物および該組成物を含む化粧料に関する。また前記組成物を添加することを特徴とする化粧料の防腐方法に関する。
(Technical field)
The present invention relates to a composition having high antibacterial properties and high preservability containing a high concentration of an acylamino acid, a hydroxamic acid derivative and a polyhydric alcohol, and a cosmetic comprising the composition. The present invention also relates to a preservative method for cosmetics, which comprises adding the composition.
(背景技術)
 近年の安全性志向の高まりによる防腐剤のイメージの低下から、市場では従来使用されてきたパラベンなどの各種防腐剤は消費者から敬遠される存在となっており、それらの防腐剤を配合せずに化粧品の防腐を行う技術が求められている。現在までに様々な素材の組み合わせを工夫して、化粧料の防腐を行う技術が数多く報告されている。しかし、それらに要求される条件は多く、例えば化粧料中における広いpHにおいての高い防腐効果や幅広い抗菌スペクトル、化粧品の各素材自体が広範囲の温度で長期にわたり優れた安定性を有すること、長期保存後でも化粧料中における性能が変化しないこと、さらに低刺激性であることや化粧料にとって重要である製品の感触に悪影響を与えないことなどが求められているが、すべての条件を満たす防腐に十分なものは報告されていない。
(Background technology)
Due to the decline in the image of preservatives due to the recent increase in safety orientation, various preservatives such as parabens that have been used in the market have been avoided by consumers, and these preservatives have not been formulated. In addition, technology for preserving cosmetics is required. To date, many techniques for preserving cosmetics by devising combinations of various materials have been reported. However, there are many conditions required for them, for example, high antiseptic effect at a wide pH in cosmetics, wide antibacterial spectrum, each cosmetic material itself has excellent stability over a long period of time at a wide range of temperatures, and long-term storage There are demands for the performance in cosmetics not to change afterwards, and that it is hypoallergenic and does not adversely affect the feel of products important to cosmetics. Not enough has been reported.
 素材の組み合わせを工夫して化粧料の防腐を行う技術として、アルキルヒドロキサム酸とアルコール(特にジオール類)を用いて化粧料を防腐する方法が提案されている(特許文献1´)。しかし、この方法ではクロコウジカビ(Aspergillus brasiliensis )などに対する防腐効果が十分ではない。さらに、低分子ジオール類については使用感や処方への影響が大きいという問題があり、あまり配合量を増やすことは好ましくなく、場合によっては低刺激性の要件も満たさない場合がある。 As a technique for preserving cosmetics by devising combinations of materials, a method for preserving cosmetics using alkylhydroxamic acid and alcohol (particularly diols) has been proposed (Patent Document 1 ′). However, this method does not have a sufficient antiseptic effect on Aspergillus brasiliensis な ど. Furthermore, there is a problem that low molecular diols have a great influence on the feeling of use and prescription, and it is not preferable to increase the blending amount so much, and in some cases, the requirement for low irritation may not be satisfied.
 一方、アシルアミノ酸は、低刺激で安全性の高い素材として知られている。なかでもアシルプロリン又はその塩は吸湿性と水分保持性に優れた保湿効果を示すこと、においが課題となる抗菌剤のにおいを抑えながら使用感に優れた化粧料を提供できることなどが報告されている(特許文献2´および3´)。またアシルグリシン又はその塩は、低刺激性でかつぬめり感がない洗浄剤組成物として利用できること(特許文献4´)、特にウンデシレノイルグリシンが抗ニキビ及び抗ふけ活性を有すること(特許文献5´)、またオクタノイルグリシンは抗アクネ、制汗剤、消臭剤などとして使用され、抗菌効果を示すことが開示されているが化粧料においてきしみ感の原因となることも報告されている(特許文献6´)。しかしアシルプロリンやアシルグリシンは、先述の化粧料の防腐を行う技術において、求められる条件を全て満たす素材としてはほど遠いのが現状であった。 On the other hand, acylamino acids are known as low-stimulation and high-safety materials. Among them, acylproline or a salt thereof has been reported to exhibit a moisturizing effect with excellent hygroscopicity and moisture retention, and to provide a cosmetic with an excellent feeling of use while suppressing the smell of antibacterial agents where odor is a problem. (Patent Documents 2 ′ and 3 ′). In addition, acylglycine or a salt thereof can be used as a detergent composition that is hypoallergenic and has no sliminess (Patent Document 4 '), and in particular, undecylenoylglycine has anti-acne and anti-dandruff activities (Patent Document 5). '), And octanoylglycine is used as an anti-acne, antiperspirant, deodorant and the like, and has been disclosed to exhibit an antibacterial effect, but it has also been reported to cause squeaky feeling in cosmetics ( Patent Document 6 '). However, the present situation is that acylproline and acylglycine are far from being materials that satisfy all the required conditions in the above-described technology for preserving cosmetics.
 また化粧料中における各素材の比率の検討、さらにそれぞれの品質管理及び製造操作が煩雑であるため、組み合わせ効果の高い各素材を予め高濃度に含有し広範囲の温度でも長期保存安定性を保ちながら、容易に化粧料に配合できる液状の防腐用組成物が求められていた。 In addition, since the examination of the ratio of each material in cosmetics and the quality control and manufacturing operations are complicated, each material with a high combination effect is contained in a high concentration in advance, while maintaining long-term storage stability over a wide range of temperatures. There has been a demand for a liquid antiseptic composition that can be easily blended into cosmetics.
