Description
本発明は防腐殺菌剤並びに該防腐殺菌剤を配合した化粧料、医薬品及び食品に係り、その目的は、炭素数５〜１０の１，２−アルカンジオールとフィトスフィンゴシン（Phytosphingosine）とを有効成分として配合することにより、１，２−アルカンジオールが本来有する抗菌力を増強する防腐殺菌剤並びに該防腐殺菌剤を配合した化粧料、医薬品及び食品を提供することにある。 The present invention relates to antiseptic fungicides and cosmetics, pharmaceuticals and foods containing the antiseptic fungicides, the purpose of which is to use 1,2-alkanediol having 5 to 10 carbon atoms and phytosphingosine as active ingredients. An object of the present invention is to provide an antiseptic and bactericidal agent that enhances the antibacterial activity inherent to 1,2-alkanediol by blending, and cosmetics, pharmaceuticals and foods containing the antiseptic and bactericidal agent.
化粧品（医薬部外品を含む）、医薬品及び食品などには、防腐殺菌剤として、パラベン、安息香酸類、サリチル酸類等が用いられている。しかしながら、上記した従来の防腐殺菌剤は皮膚刺激性が高いなど安全性が低いため、使用濃度範囲が制限されやすいといった欠点を有していた。例えば、パラベンや安息香酸塩の使用制限濃度は１％、安息香酸やサリチル酸の使用制限濃度は０．２％とされている。また、これら防腐殺菌剤はｐＨによる影響を受け易いため、防腐殺菌効果の安定性が悪く、界面活性剤などの他の配合成分との併用によりその防腐抗菌効果が著しく低下する場合があるといった問題も有していた。また、近年これらの防腐殺菌剤に対してアレルギー反応を起こす人が増えているために生活者の安全性に対する指向がより高まり、これら防腐殺菌剤を全く配合していないか、或いはその配合量を低減させた化粧料、医薬品及び食品の需要が高まっている。 Parabens, benzoic acids, salicylic acids and the like are used as antiseptic fungicides in cosmetics (including quasi-drugs), pharmaceuticals and foods. However, the above-mentioned conventional antiseptic disinfectant has a drawback that the concentration range in use is easily limited because of low safety such as high skin irritation. For example, the use restriction concentration of paraben and benzoate is 1%, and the use restriction concentration of benzoic acid and salicylic acid is 0.2%. Moreover, since these antiseptic fungicides are easily affected by pH, the stability of the antiseptic disinfection effect is poor, and the antibacterial antibacterial effect may be remarkably lowered when used in combination with other components such as surfactants. Also had. In recent years, the number of people who cause allergic reactions to these antiseptic disinfectants has increased, so the consumer's safety orientation has increased. There is a growing demand for reduced cosmetics, pharmaceuticals and foods.
そこで、従来の防腐殺菌剤を低減できる技術として、１，２−ペンタンジオールと２−フェノキシエタノールを組み合わせて配合した外用組成物（特許文献１参照）や、１，２−アルカンジオールとパラベンからなる防腐殺菌剤（特許文献２参照）が開示されている。しかし、これらは、従来の防腐剤と１，２−アルカンジオールを併用して防腐剤の効果を向上させようとするものであって、従来の防腐剤自体を完全に排除しようとするものではなく、また、１，２−アルカンジオールが有する抗菌力を増強させようとするものでもなかった。 Therefore, as a technique capable of reducing the conventional antiseptic disinfectant, an external composition (see Patent Document 1) containing a combination of 1,2-pentanediol and 2-phenoxyethanol, or an antiseptic comprising 1,2-alkanediol and paraben. A disinfectant (see Patent Document 2) is disclosed. However, these are intended to improve the effect of the preservative by combining the conventional preservative and 1,2-alkanediol, and are not intended to completely eliminate the conventional preservative itself. Also, it was not intended to enhance the antibacterial activity of 1,2-alkanediol.
一方、従来の防腐殺菌剤を排除できる技術として、１，２−アルカンジオールからなる防腐殺菌剤（特許文献３参照）や、１，２−オクタンジオールからなる洗浄性又は非洗浄性化粧料用保湿静菌剤（特許文献４参照）などが開示されている。しかし、１，２−オクタンジオールなどの１，２−アルカンジオールを単独で防腐殺菌剤として用いた場合、充分な効果性を得るためには高配合量を必要とする場合があり、また、１，２−アルカンジオールは特有の原料臭を有することから、低配合量でも充分な防腐殺菌効果を発揮できる技術が望まれている。 On the other hand, as a technique capable of eliminating the conventional antiseptic disinfectant, an antiseptic disinfectant composed of 1,2-alkanediol (see Patent Document 3), and a moisturizing agent for cleansing or non-detergent cosmetics composed of 1,2-octanediol. A bacteriostatic agent (see Patent Document 4) and the like are disclosed. However, when 1,2-alkanediol such as 1,2-octanediol is used alone as an antiseptic disinfectant, a high blending amount may be required to obtain sufficient effectiveness. Since 2-alkanediol has a peculiar raw material odor, a technology capable of exhibiting a sufficient antiseptic sterilization effect even at a low blending amount is desired.
本発明は前記従来技術に鑑みてなされたものであって、１，２−アルカンジオールと、フィトスフィンゴシンとを有効成分として共に用い、１，２−アルカンジオールが本来有する抗菌力を増強することができる防腐殺菌剤並びに該防腐殺菌剤を配合した化粧料、医薬品及び食品を提供することを課題とする。 The present invention has been made in view of the above prior art, and it is possible to use 1,2-alkanediol and phytosphingosine together as active ingredients to enhance the antibacterial activity inherent in 1,2-alkanediol. It is an object of the present invention to provide an antiseptic disinfectant that can be produced, and cosmetics, pharmaceuticals, and foods containing the antiseptic disinfectant.

The invention which concerns on Claim 4 is related with cosmetics, a pharmaceutical, or a foodstuff which mix | blended the antiseptic disinfectant in any one of Claims 1-3 as an antiseptic disinfectant.
本発明によれば、１，２−アルカンジオールの本来有する抗菌力が増強された防腐殺菌剤並びに該防腐殺菌剤を配合した化粧料、医薬品及び食品を提供することができる。 ADVANTAGE OF THE INVENTION According to this invention, the antiseptic disinfectant with which the antibacterial power which 1, 2- alkanediol originally has was enhanced, and the cosmetics, the pharmaceutical, and the foodstuff which mix | blended this antiseptic disinfectant can be provided.
本発明に係る防腐殺菌剤は、１，２−アルカンジオールとフィトスフィンゴシンを有効成分として含有する。 The antiseptic disinfectant according to the present invention contains 1,2-alkanediol and phytosphingosine as active ingredients.
本発明に係る第一の成分は、炭素数５〜１０の直鎖状のアルキル鎖を有する１，２−アルカンジオールであり、具体的には、１，２−ペンタンジオール、１，２−ヘキサンジオール、１，２−ヘプタンジオール、１，２−オクタンジオール、１，２−ノナンジオール、１，２−デカンジオールである。これらのうち、１，２−ヘキサンジオール、１，２−オクタンジオールを用いるのが好ましく、１，２−オクタンジオールを用いるのがより好ましい。尚、本発明においては、これらの１種を単独で、又は２種以上を組み合わせて用いることもできる。 The first component according to the present invention is 1,2-alkanediol having a linear alkyl chain having 5 to 10 carbon atoms, specifically 1,2-pentanediol, 1,2-hexane. Diol, 1,2-heptanediol, 1,2-octanediol, 1,2-nonanediol, and 1,2-decanediol. Of these, 1,2-hexanediol and 1,2-octanediol are preferably used, and 1,2-octanediol is more preferably used. In addition, in this invention, these 1 type can also be used individually or in combination of 2 or more types.
本発明に係る防腐殺菌剤の第二の成分は、フィトスフィンゴシンである。フィトスフィンゴシンはスフィンゴ脂質の一種であり、酵母発酵による方法等により得ることができ、市販のフィトスフィンゴシンを用いることもできる。このような市販のフィトスフィンゴシンとしては、コスモファーム（商品名、日光ケミカルズ社製）、ＤＳ−フィトスフィンゴシン（商品名、斗山社製）等を例示することができる。 The second component of the antiseptic disinfectant according to the present invention is phytosphingosine. Phytosphingosine is a kind of sphingolipid, which can be obtained by a method such as yeast fermentation, and commercially available phytosphingosine can also be used. Examples of such commercially available phytosphingosine include Cosmo Farm (trade name, manufactured by Nikko Chemicals), DS-phytosphingosine (trade name, manufactured by Doosan) and the like.
本発明に係る防腐殺菌剤においては、第一の成分である１，２−アルカンジオールと第二の成分であるフィトスフィンゴシンの含有量は特に限定されないが、重量比で０．１：１〜１０：１、好ましくは０．２：１〜５：１となるように配合する。１，２−アルカンジオールをフィトスフィンゴシンの含有量の１０重量倍を超えて配合すると、また０．１重量倍未満の場合、抗菌力の増強効果が期待できないために好ましくない。 In the antiseptic disinfectant according to the present invention, the content of 1,2-alkanediol as the first component and phytosphingosine as the second component is not particularly limited, but is 0.1: 1 to 10 by weight. : 1, preferably 0.2: 1 to 5: 1. When 1,2-alkanediol is added in an amount exceeding 10 times by weight of the phytosphingosine content, and less than 0.1 times by weight, an antibacterial activity enhancing effect cannot be expected, which is not preferable.
本発明に係る防腐殺菌剤は、第一の成分である１，２−アルカンジオールと、第二の成分であるフィトスフィンゴシンとを含有するから、後述する実施例に示されるように、第一の成分と第二の成分との相乗効果によって、抗菌力の優れた増強作用が発揮される。したがって、パラベン、安息香酸類、サリチル酸類のような従来から用いられる防腐殺菌剤を低配合又は配合する必要がなく、極めて安全性の高い防腐殺菌剤を得ることができる。 Since the antiseptic disinfectant according to the present invention contains 1,2-alkanediol as the first component and phytosphingosine as the second component, as shown in Examples described later, Due to the synergistic effect of the component and the second component, an excellent enhancing action of antibacterial activity is exhibited. Therefore, it is not necessary to blend or blend conventionally used antiseptics such as parabens, benzoic acids, and salicylic acids, and an extremely safe antiseptic can be obtained.
本発明の防腐殺菌剤は、化粧料、医薬品及び食品などに配合して使用することができる。具体的には、洗顔剤、化粧水、乳液、スキンクリーム、ファンデーション、マスカラ、ネールエナメル、口紅等の皮膚用化粧料、シャンプー、ヘアトリートメント、育毛・養毛剤、ヘアクリーム、ヘアフォーム、パーマネントウェーブ剤などの頭髪用化粧料、しみやそばかすなどの特定の使用目的を有した薬用化粧料（医薬部外品）、にきび治療薬、うがい薬、トローチ等の医薬品、チューインガム、キャンディー、飲料水等の食品に好適に用いることができる。 The antiseptic disinfectant of the present invention can be used by blending it in cosmetics, pharmaceuticals, foods and the like. Specifically, facial cleanser, lotion, milky lotion, skin cream, foundation, mascara, nail enamel, lipstick and other skin cosmetics, shampoo, hair treatment, hair growth / hair restorer, hair cream, hair foam, permanent wave agent, etc. For cosmetics for specific hair use such as cosmetics for hair, freckles and other medicinal cosmetics (quasi-drugs), acne medicines, gargles, lozenges, chewing gum, candy, drinking water and other foods It can be used suitably.
本発明の防腐殺菌剤を用いて化粧料、医薬品又は食品を調製する場合、本発明の効果を損なわない範囲内であれば、化粧料、医薬品又は食品に通常用いられる成分を適宜任意に配合することができる。例えば、化粧料（医薬部外品を含む）や医薬品の場合、油脂、ロウ類、高級脂肪酸、低級アルコール、高級アルコール、ステロール類、脂肪酸エステル、保湿剤、界面活性剤、高分子化合物、無機顔料、色素、酸化防止剤、紫外線吸収剤、ビタミン類、収斂剤、美白剤、動植物抽出物、金属イオン封鎖剤、精製水等を例示することができる。また、食品の場合は、動植物油、多糖類、甘味料、着色料、ガムベース等を例示することができる。 When preparing cosmetics, pharmaceuticals or foods using the antiseptic disinfectant of the present invention, the components usually used in cosmetics, pharmaceuticals or foods are optionally arbitrarily blended as long as the effects of the present invention are not impaired. be able to. For example, in the case of cosmetics (including quasi drugs) and pharmaceuticals, fats and oils, waxes, higher fatty acids, lower alcohols, higher alcohols, sterols, fatty acid esters, humectants, surfactants, polymer compounds, inorganic pigments , Pigments, antioxidants, ultraviolet absorbers, vitamins, astringents, whitening agents, animal and plant extracts, sequestering agents, purified water, and the like. In the case of food, animal and vegetable oils, polysaccharides, sweeteners, colorants, gum bases and the like can be exemplified.
化粧料、医薬品又は食品に本発明の防腐殺菌剤を配合する場合、配合量は特に限定されないが、組成物中０．０１〜２０重量％、好ましくは０．０５〜５重量％である。配合量が０．０１重量％未満の場合、抗菌効果に劣るために、また、２０重量％を超えて配合したとしてもそれ以上の効果が望めないからである。 When the antiseptic disinfectant of the present invention is blended in cosmetics, pharmaceuticals or foods, the blending amount is not particularly limited, but is 0.01 to 20% by weight, preferably 0.05 to 5% by weight in the composition. This is because when the amount is less than 0.01% by weight, the antibacterial effect is inferior, and even if the amount exceeds 20% by weight, no further effect can be expected.
実施例１
（共試菌）
共試菌としてPseudomonas aeruginosa IFO13275（緑膿菌）及びAspergillus niger IFO9455（クロカビ）を用いた。
Example 1
(Co-test)
Pseudomonas aeruginosa IFO13275 (Pseudomonas aeruginosa) and Aspergillus niger IFO9455 (Black mold) were used as co-test bacteria.
（接種用菌液の調製）
接種用菌液としては、緑膿菌の場合、寒天培地で３５℃で培養後、更にブイヨン培地に移植して３５℃で培養した。得られた培養液をブイヨン培地で約１０８個／ｍｌに希釈したものを接種用菌液とした。
また、クロカビの場合は、２５℃で培養後にTween 80（ポリオキシエチレン（２０）ソルビタンモノオレエート）２％加生理食塩水に胞子を懸濁させ約１０６個／ｍｌに調製したものを接種用菌液とした
(Preparation of bacterial solution for inoculation)
In the case of Pseudomonas aeruginosa, the bacterial solution for inoculation was cultured at 35 ° C. on an agar medium, then transplanted to a bouillon medium and cultured at 35 ° C. A solution obtained by diluting the obtained culture solution to about 10 8 cells / ml with a bouillon medium was used as a bacterial solution for inoculation.
In the case of black mold, after incubating at 25 ° C., inoculated with spores suspended in 2% Tween 80 (polyoxyethylene (20) sorbitan monooleate) 2% physiological saline to prepare about 10 6 cells / ml Bacteria solution
（被験物質の希釈系列の調製）
２０ｗ／ｗ％エチルセルソルブを希釈溶媒とし、５、４、３、２．５、２．２５、２、１．７５、１．５、１．２５、１ｗ／ｖ％の１，２−オクタンジオール液を調製した。
また、フィトスフィンゴシン（商品名コスモファーム、日光ケミカルズ社製）及び１，２−オクタンジオールとフィトスフィンゴシンの等量混合物については、５ｗ／ｖ％の液を倍倍希釈して希釈系列を調製した。
(Preparation of dilution series of test substance)
5, 4-, 3, 2.5, 2.25, 2, 1.75, 1.5, 1.25, 1 w / v% 1,2-octane using 20 w / w% ethyl cellosolve as a diluent solvent A diol solution was prepared.
For phytosphingosine (trade name Cosmo Farm, Nikko Chemicals) and an equal mixture of 1,2-octanediol and phytosphingosine, a dilution series was prepared by doubling a 5 w / v% solution.
（最小発育阻止濃度（ＭＩＣ）の測定）
上記被験物質を含む希釈系列１ｍＬに対して各寒天培地９ｍＬをシャーレに入れ、それぞれについて、上記接種用菌液を約１ｃｍの長さに画線した。培養は、緑膿菌については、３５℃で行い、２日後の菌の生育の有無を判定した。また、クロカビについては、２５℃で培養を行い、３日後の菌の生育の有無を判定した。このとき、生育が認められなかった最小の濃度をＭＩＣとして求めた。
その結果、緑膿菌については、１，２−オクタンジオールは3000μg/ml、フィトスフィンゴシンは1000μg/ml、１，２−オクタンジオールとフィトスフィンゴシンの等重量混合物は1000μg/mlであった。また、クロカビについては、１，２−オクタンジオールは1250μg/ml、フィトスフィンゴシンは500μg/ml、１，２−オクタンジオールとフィトスフィンゴシンの等重量混合物は500μg/mlであった。
尚、ＭＩＣによって、抗菌力を評価することができる。被験物質の濃度が薄いときには微生物への影響はないが、濃度を増していくと発育抑制が起こる。この程度は、濃度に依存して発育抑制が進み、ついには発育が停止する。このときの濃度がＭＩＣとして表される。したがって、ＭＩＣ以上の濃度になると、微生物は死滅していくことになる。
(Measurement of minimum inhibitory concentration (MIC))
For each 1 mL of the dilution series containing the test substance, 9 mL of each agar medium was placed in a petri dish, and for each, the inoculum bacterial solution was streaked to a length of about 1 cm. The culture was performed at 35 ° C. for Pseudomonas aeruginosa, and the presence or absence of the growth of the bacteria after 2 days was determined. Moreover, about black mold, it culture | cultivated at 25 degreeC and the presence or absence of the growth of a microbe after 3 days was determined. At this time, the minimum concentration at which no growth was observed was determined as MIC.
As a result, for Pseudomonas aeruginosa, 1,2-octanediol was 3000 μg / ml, phytosphingosine was 1000 μg / ml, and an equal weight mixture of 1,2-octanediol and phytosphingosine was 1000 μg / ml. For black mold, 1,2-octanediol was 1250 μg / ml, phytosphingosine was 500 μg / ml, and an equal weight mixture of 1,2-octanediol and phytosphingosine was 500 μg / ml.
In addition, antibacterial power can be evaluated by MIC. When the test substance concentration is low, there is no effect on microorganisms, but growth increases when the concentration is increased. This degree of growth proceeds depending on the concentration, and finally the growth stops. The concentration at this time is expressed as MIC. Therefore, when the concentration is higher than MIC, the microorganisms are killed.
（二元最小発育阻止濃度）
得られた１，２−オクタンジオール、フィトスフィンゴシン、及び１，２−オクタンジオールとフィトスフィンゴシンの等重量混合物の各ＭＩＣを、１，２−オクタンジオール及びフィトスフィンゴシンの配合量に対してプロットし、二元最小発育阻止濃度図を求めた。結果を図１及び図２に示す。
尚、二元最小発育阻止濃度により、抗菌性を有する二種類の物質を配合した場合の作用効果を判定することができる。具体的には、抗菌性を有する二種類の物質を配合した場合、それにより生ずる作用は、相乗作用、相加作用、拮抗作用に大別される。相乗作用とは、二薬剤が相乗的に作用し、本来有する抗菌力が更に増強される作用である。相加作用とは、各薬剤の抗菌力が合わさった作用である。拮抗作用とは、一薬剤が他剤の抗菌力を打ち消す場合の作用である。そして、二元最小発育阻止濃度図による方法は、例えば、図３に示すように、Ａ物質とＢ物質について、それぞれの割合を変えてＭＩＣを測定し、グラフから判定する方法である。これによると、Ａ物質のみにおけるＭＩＣ（点Ａ）とＢ物質のみにおけるＭＩＣ（点Ｂ）とをプロットした点を結び、両物質を併用したときのＭＩＣが、この線上より内側にある場合（点Ｃ）は、併用により抗菌力が増強された相乗作用であると、線上（点Ｄ）にある場合は相加作用であると、線上より外側にある場合（点Ｅ）は、一方又は双方の抗菌力を打ち消し抗菌力を減少させる拮抗作用であると判定することができる。
(Dual minimum inhibitory concentration)
Each MIC of the obtained 1,2-octanediol, phytosphingosine, and an equal weight mixture of 1,2-octanediol and phytosphingosine was plotted against the blending amount of 1,2-octanediol and phytosphingosine, A binary minimum inhibitory concentration diagram was determined. The results are shown in FIGS.
In addition, the effect at the time of mix | blending two types of substances which have antimicrobial property can be determined with a binary minimum growth inhibitory density | concentration. Specifically, when two kinds of substances having antibacterial properties are blended, the action caused by the substances is roughly classified into a synergistic action, an additive action, and an antagonistic action. The synergistic action is an action in which two drugs act synergistically to further enhance the inherent antibacterial power. The additive action is an action in which the antibacterial powers of the respective drugs are combined. Antagonism is an action when one drug counteracts the antibacterial activity of another drug. Then, the method based on the binary minimum growth inhibition concentration diagram is a method of determining from the graph by measuring the MIC for each of the A substance and B substance while changing their ratios, as shown in FIG. According to this, when MIC (point A) only for substance A and MIC (point B) only for substance B are connected, the MIC when both substances are used is inside this line (point C) is a synergistic effect in which the antibacterial activity is enhanced by the combined use, if it is on the line (point D), if it is an additive action, if it is outside the line (point E), one or both It can be determined that the antagonistic action counteracts the antibacterial activity and decreases the antibacterial activity.
（抗菌効果の評価）
図１及び図２の結果から、１，２−オクタンジオールとフィトスフィンゴシンとの組合せにより、抗菌力の相乗効果が認められた。
(Evaluation of antibacterial effect)
From the results of FIG. 1 and FIG. 2, a synergistic effect of antibacterial activity was recognized by the combination of 1,2-octanediol and phytosphingosine.
