Description

本発明は泡状毛髪化粧料用組成物に関する。詳しくは、泡状化粧料に求められる起泡性と泡持続性を備え、毛髪に対して優れた作用効果を発揮することが可能な泡状毛髪化粧料用組成物に関するものである。   The present invention relates to a foamy hair cosmetic composition. Specifically, the present invention relates to a composition for foamed hair cosmetics that has foaming properties and foam persistence required for foamed cosmetics and that can exhibit excellent effects on hair.

従来、毛髪へのハリの付与、損傷した毛髪の修復、あるいは整髪を目的として、天然物由来の蛋白質、特にコラーゲンやケラチン、シルク、カゼインなどの動物性蛋白質を加水分解して得られるペプチドやその誘導体を毛髪化粧料に含有させることが行われている(例えば、特許文献1〜3)。天然物由来のペプチドやその誘導体は、毛髪や皮膚に対する刺激が少なく、安全性に優れるため、消費者の天然物志向に合致した原料として、好んで用いられる傾向にある。しかしながら、これらペプチド等を含有する毛髪化粧料にあっても、製剤の安定性を改善する目的で、アニオン界面活性剤や両性界面活性剤、非イオン界面活性剤などを多量に含有している。これら界面活性剤の中には、人体に悪影響を及ぼすものも知られており、消費者のニーズに十分に対応できていないのが現状である。また、毛髪化粧料のうちクリーム状やワックス状のものは、塗布斑が発生し易いという問題があり、また液状のものは液垂れし易く、皮膚、特に顔面の皮膚に悪影響を及ぼしかねないという問題があった。   Conventionally, for the purpose of imparting elasticity to hair, repairing damaged hair, or styling hair, peptides obtained by hydrolyzing proteins derived from natural products, particularly animal proteins such as collagen, keratin, silk, and casein, and the like Derivatives are incorporated into hair cosmetics (for example, Patent Documents 1 to 3). Peptides derived from natural products and derivatives thereof are less irritating to hair and skin and are excellent in safety. Therefore, they tend to be used favorably as raw materials that match consumers' natural product orientation. However, even hair cosmetics containing these peptides contain a large amount of anionic surfactants, amphoteric surfactants, nonionic surfactants, etc. for the purpose of improving the stability of the preparation. Some of these surfactants are known to have an adverse effect on the human body, and the present situation is that they do not sufficiently meet the needs of consumers. In addition, cream-like or wax-like hair cosmetics have the problem that application spots are likely to occur, and liquids are liable to dripping, which may adversely affect the skin, especially the facial skin. There was a problem.

使用時の操作性を改善するものとして、近年、泡状の毛髪化粧料が多数提供されている。これらの中には、ペプチド等を含有するものも知られている(例えば特許文献4および5)。泡状毛髪化粧料は見かけの体積が大きいため、塗布量が確認し易い、少ない量を広い範囲に斑なく塗布できるなどの利点があり、さらに液垂れが問題となることもない。しかしながら、泡状毛髪化粧料には、起泡性や泡の持続性を改善する目的で、アニオン界面活性剤や両性界面活性剤(特許文献4)、非イオン界面活性剤(特許文献5)などを含有させるのが常である。さらに、仕上げ感を改善する目的でシリコーン誘導体や溶剤を含有させたり(特許文献4)、泡質を改善する目的でポリスチレンやその共重合体を含有させたりすることが行われている(特許文献6)。このように、界面活性剤や合成高分子化合物を多量に含有する泡状毛髪化粧料は、皮膚トラブルを招く虞があり、人体への安全性が危惧されるという問題があった。また、界面活性剤中にわずかな量のペプチド等が配合される形となり、ペプチド等が本来有する優れた作用効果が十分に発揮されないでいた。   In recent years, many foamy hair cosmetics have been provided to improve operability during use. Some of these contain peptides and the like (for example, Patent Documents 4 and 5). Foamed hair cosmetics have a large apparent volume, so that there are advantages such that the coating amount is easy to check, and small amounts can be applied in a wide range without any spots, and dripping does not become a problem. However, for foamy hair cosmetics, anionic surfactants, amphoteric surfactants (Patent Document 4), nonionic surfactants (Patent Document 5), etc., for the purpose of improving foamability and foam persistence. It is usual to contain. Furthermore, a silicone derivative or a solvent is included for the purpose of improving the finish feeling (Patent Document 4), or polystyrene or a copolymer thereof is included for the purpose of improving foam quality (Patent Document 4). 6). As described above, the foamed hair cosmetic containing a large amount of the surfactant and the synthetic polymer compound has a problem that it may cause a skin trouble, and the safety to the human body is feared. Further, a slight amount of peptide or the like is mixed in the surfactant, and the excellent action and effect inherent to the peptide or the like has not been sufficiently exhibited.

Hereinafter, the best mode for carrying out the present invention will be described in detail.
In the present specification, the “foamed hair cosmetic composition” refers to a stock solution for hair cosmetic discharged in a foamed form from a container (hereinafter simply referred to as “cosmetic composition”). Sometimes). In addition, “foamed hair cosmetic” refers to hair cosmetic discharged from a container in a foamed form, as well as a state where the cosmetic composition is filled in a container and can be discharged in a foamed form. It shall also refer to what is in For foamy cosmetics, a propellant and a cosmetic composition are filled in a pressure-resistant airtight container, and the cosmetic composition is discharged by the propellant. Non-aerosol foam that forms foam by using an aerosol foam cosmetic that inflates the foam and a foam discharge container that can be mixed with air and discharged when the cosmetic composition is discharged The cosmetic composition of the present invention can be applied to any of these.

本発明の泡状毛髪化粧料用組成物は、(A)セリシン加水分解物、(B)ケラチン分解物、および(C)エタノールを水に溶解してなることを特徴とする。(A)セリシン加水分解物と(B)ケラチン分解物を併用することにより、界面活性剤の使用を抑えても泡状毛髪化粧料に求められる起泡性と泡持続性を具備することができるとともに、毛髪にハリを付与する効果および毛髪の損傷を防止する効果を相乗的に高めることができる。さらに(C)エタノールを併用することにより、毛髪表面における(A)セリシン加水分解物および(B)ケラチン分解物の被膜性を向上させることができ、上記作用効果をより有効に発揮させることができる。   The foamed hair cosmetic composition of the present invention is characterized in that (A) a sericin hydrolyzate, (B) a keratin degradation product, and (C) ethanol are dissolved in water. By using the (A) sericin hydrolyzate and the (B) keratin decomposition product in combination, even if the use of a surfactant is suppressed, the foaming and foam sustainability required for foam hair cosmetics can be achieved. At the same time, the effect of imparting elasticity to the hair and the effect of preventing damage to the hair can be synergistically enhanced. Furthermore, by using (C) ethanol in combination, the coating properties of (A) sericin hydrolyzate and (B) keratin decomposed product on the hair surface can be improved, and the above-mentioned effects can be exhibited more effectively. .

本発明において用いられる(A)成分のセリシン加水分解物は、蚕繭、生糸などに含まれる天然蛋白質セリシンに由来するものである。セリシンを構成するアミノ酸の約30モル%がセリンであることが知られている。側鎖に水酸基を有するセリンを多く含むセリシンは、親水性が高く、毛髪に対して好ましい保湿作用を有している。また、毛髪を構成する主要蛋白質ケラチンと強固で安定な水素結合を形成することができるため、毛髪にハリを付与する効果や毛髪の損傷を防止する効果に優れている。さらに、皮膜形成能に優れるため、上記作用効果を有効に発揮させることができる。さらにまた、もう1つの蛋白質由来成分である(B)ケラチン分解物との親和性が高く、これら分子同士が水溶液中で相互作用することによって、優れた起泡性や泡持続性が得られる。さらにまた、皮膚に対する刺激性や感作性がなく、人体への安全性が高い。本発明は上記セリシンの顕著な特性に着目したものであり、これを部分加水分解して得られるセリシン加水分解物を必須成分の1つとして化粧料用組成物に含有させることを特徴とする。セリシンはそれ自体水溶性であるが、加水分解により水溶性が高まるため、水溶液として安定な性状を維持することができ、取扱い性に優れたものとなる。   The sericin hydrolyzate of component (A) used in the present invention is derived from the natural protein sericin contained in silkworms, raw silk and the like. It is known that about 30 mol% of amino acids constituting sericin is serine. Sericin containing a large amount of serine having a hydroxyl group in the side chain is highly hydrophilic and has a preferable moisturizing action on hair. Further, since it can form a strong and stable hydrogen bond with the main protein keratin constituting hair, it is excellent in the effect of imparting elasticity to the hair and the effect of preventing damage to the hair. Furthermore, since the film forming ability is excellent, the above-mentioned effects can be effectively exhibited. Furthermore, it has high affinity with (B) keratin degradation product, which is another protein-derived component, and these molecules interact with each other in an aqueous solution, whereby excellent foamability and foam persistence can be obtained. Furthermore, there is no irritation or sensitization to the skin, and safety to the human body is high. This invention pays attention to the remarkable characteristic of the said sericin, The sericin hydrolyzate obtained by partially hydrolyzing this is included in the composition for cosmetics as one of the essential components, It is characterized by the above-mentioned. Although sericin itself is water-soluble, water solubility is increased by hydrolysis, so that it can maintain stable properties as an aqueous solution and has excellent handleability.

本発明において用いられるセリシン加水分解物は、蚕繭、生糸などの原料を、塩酸、硫酸、リン酸等を使用した酸加水分解法、水酸化ナトリウム、炭酸ナトリウム等を使用したアルカリ加水分解法、微生物や植物由来のプロテアーゼを使用した酵素分解法に付すことにより、原料中のセリシンを加水分解して溶出することができる。これを分離精製することによって、高純度のセリシン加水分解物水溶液を得る。さらに、熱風乾燥、減圧乾燥、凍結乾燥などにより乾燥し、固体としてもよい。   The sericin hydrolyzate used in the present invention is a raw material such as silkworm, raw silk, acid hydrolysis method using hydrochloric acid, sulfuric acid, phosphoric acid, etc., alkali hydrolysis method using sodium hydroxide, sodium carbonate, etc., By subjecting to an enzymatic decomposition method using a microorganism or plant-derived protease, sericin in the raw material can be hydrolyzed and eluted. By separating and purifying this, a highly pure sericin hydrolyzate aqueous solution is obtained. Further, it may be dried by hot air drying, reduced pressure drying, freeze drying, or the like to form a solid.

セリシン加水分解物の平均分子量は、1,000〜100,000であることが好ましく、より好ましくは5,000〜50,000である。平均分子量が1,000未満であると、ペプチド鎖が短いため、分子間の相互作用が弱く、十分な起泡性と泡持続性、特に起泡性が得られない虞がある。平均分子量が100,000を超えると、水溶性が低下することにより、水溶液として安定な性状を維持することができず、十分な起泡性が得られない虞がある。   The average molecular weight of the sericin hydrolyzate is preferably 1,000 to 100,000, more preferably 5,000 to 50,000. If the average molecular weight is less than 1,000, since the peptide chain is short, the interaction between molecules is weak, and there is a possibility that sufficient foaming properties and foam persistence, particularly foaming properties may not be obtained. If the average molecular weight exceeds 100,000, the water solubility decreases, so that stable properties as an aqueous solution cannot be maintained, and sufficient foaming properties may not be obtained.

セリシン加水分解物の含有量は、求められる使用感に応じて調整することができるが、化粧料用組成物の全重量に対して0.01〜10重量%であることが好ましく、より好ましくは0.1〜5重量%である。含有量が0.01重量%未満であると、ペプチド分子間の相互作用が弱く、十分な起泡性が得られない虞がある。含有量が10重量%を超えると、泡状毛髪化粧料として毛髪に塗布した際に、べたつき感やごわつき感などの好ましくない使用感を与える虞がある。   The content of sericin hydrolyzate can be adjusted according to the required feeling of use, but is preferably 0.01 to 10% by weight, more preferably based on the total weight of the cosmetic composition. 0.1 to 5% by weight. If the content is less than 0.01% by weight, the interaction between peptide molecules is weak, and there is a possibility that sufficient foaming properties cannot be obtained. When the content exceeds 10% by weight, there is a possibility of giving an unpleasant feeling of use such as stickiness or stiffness when applied to the hair as a foam hair cosmetic.

次にもう1つの蛋白質由来成分である(B)ケラチン分解物について説明する。
本発明において用いられる(B)成分のケラチン分解物は、毛(獣毛、羽毛、毛髪など)、角、爪、蹄などを構成する主要な天然蛋白質ケラチンに由来するものである。ケラチンは、含硫アミノ酸を豊富に含むことが知られている。特にシステイン残基は分子内、分子間に複数のジスルフィド結合(シスチン結合)を形成することによって、ケラチンを物理的にも化学的にも強靭なものとしている。このケラチンを部分分解して得られるケラチン分解物は、毛髪との親和性に優れており、硫黄原子を介して毛髪ケラチンと強固なジスルフィド結合を形成することができるため、毛髪にハリを付与する効果や毛髪の損傷を防止する効果に優れている。さらに、皮膜形成能に優れるため、上記作用効果を有効に発揮させることができる。さらにまた、皮膚に対する刺激性や感作性がなく、人体への安全性が高い。
Next, (B) keratin degradation product which is another protein-derived component will be described.
The keratin degradation product of the component (B) used in the present invention is derived from the main natural protein keratin constituting hair (animal hair, feathers, hair, etc.), horns, nails, hoofs and the like. Keratin is known to be rich in sulfur-containing amino acids. In particular, cysteine residues make keratin physically and chemically strong by forming multiple disulfide bonds (cystine bonds) within and between molecules. The keratin degradation product obtained by partially decomposing this keratin is excellent in affinity with hair and can form a strong disulfide bond with hair keratin via a sulfur atom, thus imparting elasticity to the hair. It is excellent in the effect and the effect of preventing hair damage. Furthermore, since the film forming ability is excellent, the above-mentioned effects can be effectively exhibited. Furthermore, there is no irritation or sensitization to the skin, and safety to the human body is high.

本発明において用いられるケラチン分解物の原料としては、毛(獣毛、羽毛、毛髪など)、角、爪、蹄などを挙げることができるが、なかでも、入手が容易であるという観点から羊毛が好ましい。
ケラチン分解物としては加水分解物、酸化分解物、還元分解物などを挙げることができ、これらは公知の方法によって取得することができる。例えば、羊毛などの原料を、塩酸、硫酸、リン酸等を使用した酸加水分解法、水酸化ナトリウム、炭酸ナトリウム等を使用したアルカリ加水分解法、微生物や植物由来のプロテアーゼを使用した酵素分解法に付すことにより、原料中のケラチンを加水分解して溶出することができる。これを分離精製することによって、高純度のケラチン加水分解物水溶液を得る。さらに、熱風乾燥、減圧乾燥、凍結乾燥などにより乾燥し、固体としてもよい。
Examples of the raw material of the keratin degradation product used in the present invention include hair (animal hair, feathers, hair, etc.), horns, nails, hoofs, etc. Among these, wool is easily obtained from the viewpoint of availability. preferable.
Examples of keratin degradation products include hydrolysates, oxidative degradation products, and reductive degradation products, and these can be obtained by known methods. For example, raw materials such as wool are acid hydrolyzed using hydrochloric acid, sulfuric acid, phosphoric acid, etc., alkaline hydrolyzing using sodium hydroxide, sodium carbonate, etc., and enzymatic degrading using microorganisms or plant-derived proteases By attaching to, keratin in the raw material can be hydrolyzed and eluted. By separating and purifying this, a highly pure keratin hydrolyzate aqueous solution is obtained. Further, it may be dried by hot air drying, reduced pressure drying, freeze drying, or the like to form a solid.

こうして得られるケラチン分解物のシスチン含有量は3〜30モル%であり、そのいずれも使用可能であるが、なかでもヒト毛髪ケラチンのシスチン含有量(15モル%)に近い10〜20モル%が好ましい。ケラチン分解物のシスチン含有量がヒト毛髪ケラチンのシスチン含有量と近似であることにより、毛髪との親和性が高く、毛髪との結合性が向上する。   The keratin degradation product thus obtained has a cystine content of 3 to 30 mol%, and any of them can be used. Among them, 10 to 20 mol% close to the cystine content (15 mol%) of human hair keratin is 10 to 20 mol%. preferable. When the cystine content of the keratin degradation product is close to the cystine content of human hair keratin, the affinity for hair is high and the binding property to hair is improved.

ケラチン分解物の平均分子量は、200〜30,000であることが好ましく、より好ましくは500〜5000である。平均分子量が200未満であると、ペプチド鎖が短いため、分子間の相互作用が弱く、十分な起泡性と泡持続性、特に泡持続性が得られない虞がある。平均分子量が30,000を超えると、水溶性が低下することにより、水溶液として安定な性状を維持することができず、十分な泡持続性が得られない虞がある。   The average molecular weight of the keratin degradation product is preferably 200 to 30,000, more preferably 500 to 5,000. If the average molecular weight is less than 200, since the peptide chain is short, the interaction between the molecules is weak, and there is a possibility that sufficient foaming properties and foam persistence, particularly foam persistence cannot be obtained. If the average molecular weight exceeds 30,000, the water solubility decreases, so that stable properties cannot be maintained as an aqueous solution, and sufficient foam persistence may not be obtained.

ケラチン分解物の含有量は、求められる使用感に応じて調整することができるが、化粧料用組成物の全重量に対して0.01〜10重量%であることが好ましく、より好ましくは0.1〜5重量%である。含有量が0.01%未満であると、ペプチド分子間の相互作用が弱く、十分な泡持続性が得られない虞がある。含有量が10重量%を超えると、泡状毛髪化粧料として毛髪に塗布した際に、べたつき感やごわつき感などの好ましくない使用感を与える虞がある。   The content of the keratin degradation product can be adjusted according to the required feeling of use, but is preferably 0.01 to 10% by weight, more preferably 0, based on the total weight of the cosmetic composition. .1 to 5% by weight. If the content is less than 0.01%, the interaction between peptide molecules is weak, and sufficient foam persistence may not be obtained. When the content exceeds 10% by weight, there is a possibility of giving an unpleasant feeling of use such as stickiness or stiffness when applied to the hair as a foam hair cosmetic.

(A)セリシン加水分解物と(B)ケラチン分解物の総含有量は、化粧料用組成物の全重量に対して0.05〜20重量%であることが好ましく、より好ましくは0.2〜10重量%である。
また、(A)セリシン加水分解物と(B)ケラチン分解物の配合比率は、重量濃度比(B)/(A)で0.1〜10であることが好ましく、より好ましくは0.2〜5である。当該比が0.1未満であると、起泡性は十分であるが、泡持続性が不十分となる虞がある。当該比が10を超えると、泡持続性は十分であるが、起泡性が不十分となる虞がある。この比率で(A)セリシン加水分解物と(B)ケラチン分解物を併用することにより、泡状毛髪化粧料に求められる起泡性と泡持続性を高度に具備することができ、毛髪への塗布操作性を改善するとともに毛髪への被膜性を向上させる結果、毛髪にハリを付与する効果および毛髪の損傷を防止する効果を相乗的に高めることができる。
The total content of (A) sericin hydrolyzate and (B) keratin degradation product is preferably 0.05 to 20% by weight, more preferably 0.2%, based on the total weight of the cosmetic composition. -10% by weight.
Moreover, it is preferable that the mixture ratio of (A) sericin hydrolyzate and (B) keratin degradation product is 0.1-10 by weight concentration ratio (B) / (A), More preferably, it is 0.2- 5. When the ratio is less than 0.1, the foaming property is sufficient, but the foam sustainability may be insufficient. When the ratio exceeds 10, the foam persistence is sufficient, but the foamability may be insufficient. By using together (A) sericin hydrolyzate and (B) keratin decomposer at this ratio, the foaming and foam sustainability required for foam hair cosmetics can be provided to a high degree. As a result of improving the coating operability and improving the coating property on the hair, the effect of imparting elasticity to the hair and the effect of preventing hair damage can be synergistically enhanced.

残る必須成分である(C)エタノールについて説明する。
本発明において(C)成分のエタノールは、毛髪表面における(A)セリシン加水分解物および(B)ケラチン分解物の被膜性をより向上させるために用いられる。エタノールを併用することにより、セリシン加水分解物およびケラチン分解物の分子表面に存在する水和水が奪われ、分子間の結合力が高まって、毛髪への被膜性が向上する。もって、毛髪にハリを付与する効果および毛髪の損傷を防止する効果をより有効に発揮させることができる。エタノールの含有量は、化粧料組成物の全重量に対して1〜20重量%であることが好ましく、より好ましくは1〜10重量%である。含有量が1重量%未満であると、エタノールを用いることによる上記作用効果が十分に発揮されない虞がある。含有量が20重量%を超えると、起泡性が損なわれる虞がある。
The remaining essential component (C) ethanol will be described.
In the present invention, (C) component ethanol is used to further improve the coating properties of (A) sericin hydrolyzate and (B) keratin decomposed product on the hair surface. By using ethanol in combination, the water of hydration present on the molecular surface of the sericin hydrolyzate and keratin degradation product is deprived, the bonding force between the molecules is increased, and the coating property on the hair is improved. Thus, the effect of imparting elasticity to the hair and the effect of preventing damage to the hair can be more effectively exhibited. The content of ethanol is preferably 1 to 20% by weight, more preferably 1 to 10% by weight, based on the total weight of the cosmetic composition. There exists a possibility that the said effect by using ethanol as the content is less than 1 weight% may not fully be exhibited. If the content exceeds 20% by weight, the foamability may be impaired.

Moreover, even when it contains surfactant for the purpose of the further improvement of foamability and foam persistence, the content can be suppressed compared with the composition for conventional cosmetics. Therefore, it is excellent in safety.

本発明において任意成分(D)として用いられる界面活性剤は、特に限定されるものでなく、非イオン界面活性剤、アニオン界面活性剤、カチオン界面活性剤、両性活性剤のいずれも使用可能であるが、なかでも、乳化性、可溶化性、および分散性に優れた非イオン界面活性剤が好ましく、耐酸性、耐アルキル性、および耐熱性に優れたエーテル型非イオン界面活性剤がより好ましい。エーテル型非イオン界面活性剤として具体的には、ポリオキシエチレンラウリルエーテル(POE付加モル数2〜50)、ポリオキシエチレンセチルエーテル(POE付加モル数2〜40)、ポリオキシエチレンステアリルエーテル(POE付加モル数2〜40)、ポリオキシエチレンオレイルエーテル(POE付加モル数2〜50)、ポリオキシエチレンヘキシルデシルエーテル(POE付加モル数10〜30)、ポリオキシエチレンイソステアリルエーテル(POE付加モル数10〜30)、ポリオキシエチレンオクチルドデシルエーテル(POE付加モル数5〜30)、ポリオキシエチレンベヘニルエーテル(POE付加モル数5〜30)、ポリオキシエチレンデシルペンタデシルエーテル(POE付加モル数10〜30)、ポリオキシエチレンデシルテトラデシルエーテル(POE付加モル数5〜30)、ポリオキシエチレンコレステリルエーテル(POE付加モル数5〜30)、ポリオキシエチレン・ポリオキシプロピレンデシルエーテル(POE付加モル数7〜30)等を挙げることができ、これらを1種単独でまたは2種以上組み合わせて用いることができる。   The surfactant used as the optional component (D) in the present invention is not particularly limited, and any of nonionic surfactants, anionic surfactants, cationic surfactants, and amphoteric surfactants can be used. However, among these, nonionic surfactants excellent in emulsifying properties, solubilization properties, and dispersibility are preferable, and ether type nonionic surfactants excellent in acid resistance, alkyl resistance, and heat resistance are more preferable. Specific examples of ether type nonionic surfactants include polyoxyethylene lauryl ether (POE addition mole number 2 to 50), polyoxyethylene cetyl ether (POE addition mole number 2 to 40), polyoxyethylene stearyl ether (POE). Addition mole number 2-40), polyoxyethylene oleyl ether (POE addition mole number 2-50), polyoxyethylene hexyl decyl ether (POE addition mole number 10-30), polyoxyethylene isostearyl ether (POE addition mole number) 10-30), polyoxyethylene octyldodecyl ether (5-30 POE addition moles), polyoxyethylene behenyl ether (5-30 POE addition moles), polyoxyethylene decyl pentadecyl ether (10 POE addition moles 10). 30), Polyoki Ethylene decyl tetradecyl ether (POE addition mole number 5-30), polyoxyethylene cholesteryl ether (POE addition mole number 5-30), polyoxyethylene polyoxypropylene decyl ether (POE addition mole number 7-30), etc. These may be used alone or in combination of two or more.

これらエーテル型非イオン界面活性剤のHLBは7〜20であることが好ましい。界面活性剤の作用は、2相の界面において親水基、親油基がそれぞれの相に対して示す親水性、親油性によって決まると考えられている。この親水性と親油性のバランスを数値で表したものがHLBであり、値が小さいほど親油性が高く、値が大きいほど親水性が高いことを意味する。HLBが7未満であると、起泡性や泡持続性の向上効果が十分に得られない虞がある。HLBが20を超えると、安定な化粧料用組成物が得られない虞がある。   These ether type nonionic surfactants preferably have an HLB of 7-20. It is considered that the action of the surfactant is determined by the hydrophilicity and lipophilicity of the hydrophilic group and lipophilic group for each phase at the two-phase interface. A numerical value representing the balance between hydrophilicity and lipophilicity is HLB. The smaller the value, the higher the lipophilicity, and the higher the value, the higher the hydrophilicity. If the HLB is less than 7, the effect of improving the foamability and foam sustainability may not be sufficiently obtained. If the HLB exceeds 20, a stable cosmetic composition may not be obtained.

表1および2から明らかなように、実施例1〜10の泡状毛髪化粧料用組成物および泡状毛髪化粧料は、起泡性、泡持続性、毛髪への塗布操作性、毛髪へのハリ付与効果、および毛髪の損傷防止効果の諸特性に優れている。
これに対し、比較例1〜4はいずれの特性についても優れた点が認められない。また、比較例5および8はエタノールを含まないため、十分なハリ付与効果や損傷防止効果が得られない。また、比較例6および7は界面活性剤を含むため起泡性は良いが、泡持続性が不十分であるため塗布操作性が悪く、十分なハリ付与効果や損傷防止効果が得られない。比較例9および10は、液状で塗布するために塗布操作性が悪く、毛髪への被膜性が低いために、ハリ付与効果、損傷防止効果が得られない。
As apparent from Tables 1 and 2, the foam hair cosmetic compositions and foam hair cosmetics of Examples 1 to 10 are foaming properties, foam persistence, operability for application to hair, It is excellent in various properties such as a firmness imparting effect and a hair damage preventing effect.
On the other hand, the comparative examples 1-4 are not recognized as being excellent in any characteristics. Further, since Comparative Examples 5 and 8 do not contain ethanol, a sufficient elasticity imparting effect and damage preventing effect cannot be obtained. Further, Comparative Examples 6 and 7 contain a surfactant and thus have good foaming properties. However, since the foam sustainability is insufficient, the coating operability is poor, and sufficient elasticity imparting effects and damage preventing effects cannot be obtained. Since Comparative Examples 9 and 10 are applied in a liquid state, the application operability is poor, and the coating property on the hair is low, so that the elasticity imparting effect and the damage preventing effect cannot be obtained.
