Description

  The present invention relates to a foam cosmetic additive that contains γ-polyglutamic acid and honey as active ingredients and can improve foaming and foam quality of the foam cosmetic.

  In general, shampoos, body soaps, hand soaps, facial cleansers, and soaps are known as foam cosmetics to be used in the form of foam when used. These foam cosmetics are blended with conditioning ingredients to improve foaming during use, the amount of foam, and foam quality, for example foam fineness, elasticity, durability, and adhesion to the application area. Sometimes. For example, foam cosmetics disclosed in Patent Documents 1 and 2 are known. These foam cosmetics contain a specific water-soluble polymer in order to improve the foam quality in addition to the surfactant. The foam cosmetic of Patent Document 1 contains a semi-synthetic polymer such as cationized starch as a water-soluble polymer. Patent Document 2 contains an acrylic acid polymer as a water-soluble polymer.

JP 2008-189582 A JP 2009-249330 A JP 2009-149567 A

  However, the foam cosmetics of Patent Documents 1 and 2 still have a problem that the effect of improving foaming and foam quality is still insufficient. Moreover, since the conditioning component which improves foaming and foam quality is contained in cosmetics from the beginning, it is difficult to adjust foaming and foam quality according to a use purpose, an application location, etc.

  By the way, honey and γ polyglutamic acid (γPGA) are conventionally known as moisturizing ingredients blended in cosmetics (Patent Document 3). However, it has not yet been known about improving the foaming and foam quality of foamy cosmetics by using these components in combination.

  The present invention is based on the discovery that the foam quality of foam cosmetics can be greatly improved by using honey and γ-polyglutamic acid in combination. Moreover, by comprising as an additive for foam cosmetics, foaming and foam quality can be easily improved and the foaming and foam quality can be adjusted for various foam cosmetics.

  An object of the present invention is to provide an additive for foamed cosmetics that can easily improve foaming and foam quality of the foamed cosmetics.

To achieve the above object, a foam cosmetic additive according to claim 1, containing a γ-polyglutamic acid and honey as an active ingredient, the γ-polyglutamic acid has an average molecular weight of 1000kDa~6000kDa foam In the cosmetic for cosmetics, the mass ratio of the content of the honey to the content of the γ-polyglutamic acid in the additive for cosmetics in the foam is 199 to 1999 .

The invention described in 請 Motomeko 2, in a foam cosmetic additive according to claim 1, with respect to the amount of foam cosmetic material, were mixed at a ratio of 0.1 to 10 as a mass ratio used It is characterized by being.

  ADVANTAGE OF THE INVENTION According to this invention, the foam cosmetic additive which can improve foaming and foam quality of a foam cosmetic simply can be provided.

Hereinafter, the embodiment which actualized the additive for foamy cosmetics of this invention is described.
The foam cosmetic additive of this embodiment contains γ polyglutamic acid and honey as active ingredients. Honey improves the foaming property and foam quality of foamy cosmetics when used in combination with γ-polyglutamic acid. In addition, honey further improves the moisturizing performance of the foamy cosmetic when used in combination with γ-polyglutamic acid. The production area of honey used in the present embodiment is not particularly limited. For example, any of Asian countries such as China, Taiwan and Japan, European countries, North American countries, South American countries such as Brazil, and Oceanian countries such as Australia. But you can. Further, the dense source plant of honey is not particularly limited, and examples thereof include astragalus, false acacia, rosemary, orange, lemon, eucalyptus, mandarin orange, clover, buckwheat, chestnut, lavender, and coffee.

  Even if a part of the honey blended in the additive for foamy cosmetics is replaced with at least one substitution component selected from sugars other than honey and polyhydric alcohols, the foaming properties and foam quality of the foamed cosmetics The effect of improving can be maintained. The blending amount of saccharides other than honey and polyhydric alcohol into honey is preferably 75% by mass or less (25% by mass or more of honey) with respect to the amount of original honey used (100% by mass). ), More preferably 50% by mass or less (honey 50% by mass or more), and further preferably 30% by mass or less (honey 70% by mass or more). In order to obtain the effect of improving the foamability and foam quality of the foamy cosmetic, a part of the honey can be replaced with an ingredient that is cheaper or easier to obtain than honey. As sugars other than honey, simple sugars such as glucose, fructose, xylose, arabinose, mannose, and galactose, small sugars such as maltose, lactose, sucrose, trehalose, and raffinose, oligosaccharides such as xylooligosaccharide, isomaltoligosaccharide, Examples include galactooligosaccharides, coffee bean manno-oligosaccharides, soybean oligosaccharides, dairy oligosaccharides, fructo-oligosaccharides, and lactulose, and polysaccharides. Examples of the polyhydric alcohol include glycerin, xylitol, sorbitol, propylene glycol, butylene glycol, and di-polyglycerin.

  γ-polyglutamic acid improves the foaming property and foam quality of the foamy cosmetic when used in combination with the honey. Moreover, (gamma) polyglutamic acid improves the moisture retention performance of foamy cosmetics further by using together with honey. γ-polyglutamic acid is a kind of polypeptide having glutamic acid as a polymerization unit, and a carboxyl group at the γ-position and an amino group at the α-position form a peptide bond. γ-polyglutamic acid may be derived from a natural product or chemically synthesized. Moreover, you may obtain a commercial item. Since γ-polyglutamic acid is secreted from Bacillus natto and Bacillus anthracis, it may be extracted from these cells or secretions using a known method.

  The average molecular weight of γ polyglutamic acid is not particularly limited, but is preferably 50 kDa to 7000 kDa, more preferably 1000 kDa to 6000 kDa, and further preferably 2000 kDa to 5000 kDa. If the average molecular weight of γ polyglutamic acid is less than 50 kDa, the effect of improving foamability and foam quality may be reduced. When the average molecular weight of γ polyglutamic acid exceeds 7000 kDa, the effect of improving foamability and foam quality may be reduced. The average molecular weight of γ polyglutamic acid can be determined by using a molecular sieve such as gel electrophoresis, filtration, and molecular exclusion chromatography.

The mass ratio of the honey content to the γ polyglutamic acid content in the foam cosmetic additive (honey content / γ polyglutamic acid content) is preferably 199 to 1999 , more preferably 500 to 1500. It is. When the mass ratio of the content of honey to the content of γ-polyglutamic acid is less than 199 , since the proportion of the content of γ-polyglutamic acid is large, the additive for foamed cosmetics gels, Mixability and handleability may be reduced. If the mass ratio of the content of honey to the content of γ-polyglutamic acid exceeds 1999 , the effect of improving foaming properties and foam quality may be reduced.

  The additive for foamy cosmetics is used by blending into the foamed cosmetics used in the form of foams at the time of use. Examples of the foam cosmetic used in the form of foam when used include shampoos, body soaps, hand soaps, facial cleansers, and soaps. The foam cosmetic additive and the foam cosmetic are mixed while adjusting foaming and foam quality according to, for example, the components, type, usage purpose and application location of the foam cosmetic. The mixing ratio of the foam cosmetic additive and the foam cosmetic is not particularly limited as long as desired foaming and foam quality can be obtained, but from the viewpoint of further improving foaming and foam quality, a mass ratio is preferable. 0.1 to 10: 1, more preferably 0.5 to 1.5: 1. When the foam cosmetic is a shampoo, the mass ratio is preferably 0.1 to 10: 1, more preferably 0.5 to 5: 1.

Examples are given below to describe the above embodiments more specifically, but the present invention is not limited to these examples.
<Preparation of foam cosmetic additive>
0.1% by mass of each γ-polyglutamic acid (γPGA: manufactured by BioLeaders) having an average molecular weight of 50 kDa, 500 kDa, 2000 kDa, 5000 kDa, and 7000 kDa was added to honey, which is a dense source plant. And each additive for foamy cosmetics was produced by stirring overnight.

<Test Example 1: Foam elasticity test 1>
Each foam cosmetic additive and a commercial foam cosmetic were mixed and foamed, and then the elasticity of the foam was evaluated by measuring the time for foam collapse. As the commercially available foam cosmetics, foam cosmetics A, B, and C, which are the face wash shown in Table 1, were used. 0.6 g of each foam cosmetic additive and 0.9 g of foam cosmetic A were taken on the palm and foamed by rubbing the palms for 1 minute 30 seconds. Each foam cosmetic additive 0.6 g and foam cosmetic B 0.6 g or foam cosmetic C 0.6 g was foamed by stirring with a foaming ball. For each foamed cosmetic after whipping, measure the time required for a 1-yen coin to contact the board after placing a certain amount on the board and placing 1-yen coin (1 g) on it. (N = 5). Table 2 shows the relative values (average values) when the time when foaming only each commercially available foam cosmetic material as a control is 100 is shown. As comparative examples, evaluations were similarly made for those in which the foam cosmetic additive was composed only of honey and in which the foam cosmetic additive was composed only of γPGA (molecular weight: 2000 kDa).

表２に示されるように、蜂蜜のみから泡状化粧料用添加剤を構成した場合、いずれの泡状化粧料と混合しても泡の弾力性が低下することが確認された。γＰＧＡのみから泡状化粧料用添加剤を構成した場合、いずれの泡状化粧料と混合しても泡の弾力性はほとんど変わらないことが確認された。蜂蜜とγＰＧＡから泡状化粧料用添加剤を構成した場合、特に平均分子量が２０００〜５０００ｋＤａの範囲において優れた泡の弾力性の向上効果が得られることが確認された。

As shown in Table 2, when the foam cosmetic additive was composed of honey alone, it was confirmed that the foam elasticity decreased even when mixed with any foam cosmetic. In the case where the foam cosmetic additive is composed only of γPGA, it was confirmed that the elasticity of the foam hardly changes even when mixed with any foam cosmetic. When the additive for foamy cosmetics was composed of honey and γPGA, it was confirmed that an excellent effect of improving the foam elasticity was obtained particularly in the range of the average molecular weight of 2000 to 5000 kDa.

<Test Example 2: Foam elasticity test 2>
Each foam cosmetic additive described above and a commercial foam cosmetic were mixed and foamed, and then the elasticity of the foam was evaluated by measuring the weight of foam collapse. As a commercially available foam cosmetic, the foam cosmetic A shown in Table 1 was used. 0.6 g of each foam cosmetic additive and 0.9 g of foam cosmetic A were taken on the palm and foamed by rubbing the palms for 1 minute 30 seconds. About foamed cosmetics after whipping, place a certain amount on the board, put 1 yen coin (1g) on it one by one, and measure the weight required for 1 yen coin to contact the board (N = 3). Table 2 shows the relative value (average value) when the weight when only the foamy cosmetic A as a control is foamed is 100. As comparative examples, evaluations were similarly made for those in which the foam cosmetic additive was composed only of honey and in which the foam cosmetic additive was composed only of γPGA (molecular weight: 2000 kDa).

表３に示されるように、本試験においては、蜂蜜とγＰＧＡから泡状化粧料用添加剤を構成した場合、平均分子量が２０００〜５０００ｋＤａの範囲において優れた泡の弾力性の向上効果が得られることが確認された。

As shown in Table 3, in this test, when the foam cosmetic additive is composed of honey and γPGA, an excellent foam elasticity improving effect is obtained in the range of the average molecular weight of 2000 to 5000 kDa. It was confirmed.

<Test Example 3: Moisturizing test>
Each of the above foam cosmetic additives and a commercial foam cosmetic were mixed, applied to the face and washed, and then the moisture value of the cheek skin was measured. As a commercially available foam cosmetic, foam cosmetic C shown in Table 1 was used. Each foam cosmetic additive 0.6g and foam cosmetic C 0.6g were foamed by stirring with a foaming ball. The foamed cosmetic after foaming was applied to the face and washed according to a conventional method. After washing, excess water was wiped off with a towel. The moisture content of the cheek skin after face washing was measured with a skin viscoelasticity measuring device cut meter (MPA580: manufactured by Integral) every predetermined time (N = 2). Table 4 shows the relative values when the moisture value of the skin of the cheeks before washing as a control is taken as 100. As comparative examples, evaluations were similarly made for those in which the foam cosmetic additive was composed only of honey and in which the foam cosmetic additive was composed only of γPGA (molecular weight: 2000 kDa). Moreover, the same evaluation was performed when the face was washed using only the foam cosmetic C that was not mixed with the foam cosmetic additive.

表４に示されるように、蜂蜜とγＰＧＡから泡状化粧料用添加剤を構成した場合、特に平均分子量が２０００〜５０００ｋＤａの範囲において、蜂蜜のみ又はγＰＧＡのみから泡状化粧料用添加剤を構成した場合と比べ、明らかに優れた保湿性の向上効果が得られることが認められた。特に、洗顔後１２０分経過後の皮膚の水分値について顕著な差が認められた。これは空気中の水分を吸収し保湿性を高めたものと思料される。尚、泡状化粧料Ｂについて、蜂蜜及び平均分子量２０００〜５０００ｋＤａのγＰＧＡを併用した泡状化粧料用添加剤と混合した場合にも比較例に対し優れた保湿性の向上効果が得られることが認められた。（データ不添付）。

As shown in Table 4, when the foam cosmetic additive is composed of honey and γPGA, the foam cosmetic additive is composed only of honey or γPGA, particularly in the range of 2000 to 5000 kDa in average molecular weight. As compared with the case where it did, it was recognized that the outstanding improvement effect of moisture retention was acquired. In particular, a remarkable difference was recognized in the moisture value of the skin after 120 minutes from the face washing. This is considered to have absorbed moisture in the air and improved moisture retention. In addition, about foam cosmetic B, when it mixes with the additive for foam cosmetics which used together honey and (gamma) PGA of average molecular weight 2000-5000 kDa, the improvement effect of the outstanding moisture retention with respect to a comparative example is acquired. Admitted. (Data not attached).

<Test Example 4: Evaluation of foaming and foam quality>
Each foam cosmetic additive described above and a commercially available foam cosmetic were mixed and foamed, and then sensory evaluation was performed on foaming and foam quality. As commercially available foam cosmetics, foam cosmetics B and C shown in Table 1 were used. In addition, the foam cosmetics B and C which were not mixed with each additive for foam cosmetics were used as control. As comparative examples, a foam cosmetic additive composed only of honey and a foam cosmetic additive composed only of γPGA (average molecular weight: 2000 kDa) were used. Each foam cosmetic additive 0.6 g and foam cosmetic B 0.6 g or foam cosmetic C 0.6 g was foamed by stirring for 1 minute 30 seconds (about 150 rotations) using a foaming ball. At the time of foaming, panelists (10 persons) judged whether the ease of foaming, the amount of foam, the fineness of foam, the elasticity of foam, and the adhesion of foam were better than the control. The results of sensory evaluation were determined according to the following criteria from the judgment of each panel. The results are shown in Table 5.
◎: More than 8 people answered that it was better than control ○: More than 6 people answered that it was better than control △: More than 4 people answered that it was better than control ×: Less than 6 people Less than 4 people answered better

表５に示されるように、蜂蜜とγＰＧＡから泡状化粧料用添加剤を構成した場合、特に平均分子量が２０００〜５０００ｋＤａの範囲において、蜂蜜のみ又はγＰＧＡのみから泡状化粧料用添加剤を構成した場合と比べて、明らかに優れた泡立ち及び泡質の向上効果が認められた。一方、比較例としての蜂蜜のみ又はγＰＧＡのみから泡状化粧料用添加剤を構成した場合、泡立ち及び泡質の評価はコントロールと変わらない又はコントロールより劣る傾向にあることが確認された。

As shown in Table 5, when the foam cosmetic additive is composed of honey and γPGA, the foam cosmetic additive is composed only of honey or γPGA, particularly in the range of 2000 to 5000 kDa in average molecular weight. Compared with the case where it did, apparently the foaming and the improvement effect of foam quality were recognized. On the other hand, when the additive for foamy cosmetics was composed of only honey or γPGA as a comparative example, it was confirmed that the evaluation of foaming and foam quality was not different from the control or inferior to the control.

<Test Example 5: Evaluation of foaming at the time of foaming, foam quality and feeling of use, feeling of use when rinsing cosmetics, and feeling after use, etc.>
Foam cosmetic additive containing honey and γPGA (average molecular weight 2000 kDa) and commercially available foam cosmetic are mixed, then foaming, foam quality and feeling of use, etc. And the feeling after use were evaluated. As a commercially available foam cosmetic, foam cosmetic B or C shown in Table 1 was used. In addition, the foam cosmetics B or C which are not mixed with the additive for foam cosmetics were used as control. As a comparative example, a foam cosmetic additive composed only of honey was used.

The above foam cosmetic additive 0.6g and foam cosmetic B or C 0.6g were foamed by stirring for 1 minute 30 seconds (about 150 rotations) using a foaming ball. Panelers (10 persons) washed their face according to a conventional method using the foamed cosmetic material after whipping. After washing, excess water was wiped off with a towel. The panelists evaluated each of foaming, foam quality, and feeling of use shown in Table 6 below when foaming, rinsing, and after washing (after use). When the evaluation of the control was 3 (normal), the score was assigned according to the criteria shown below. Table 6 shows the average points of the panelists.
10: very good, 5: good, 3: normal (control), 2: bad, 1: very bad.

表６に示されるように、蜂蜜とγＰＧＡ（平均分子量２０００ｋＤａ）を含有する泡状化粧料用添加剤と市販の泡状化粧料を混合した場合、泡立て時の泡立ち、泡質及び使用感等、化粧料の濯ぎ時の使用感等、並びに使用後の使用感等の各評価は、蜂蜜のみからなる泡状化粧料用添加剤を使用した比較例に対し、顕著に優れることが確認された。

As shown in Table 6, when a foam cosmetic additive containing honey and γPGA (average molecular weight 2000 kDa) and a commercially available foam cosmetic are mixed, foaming at the time of foaming, foam quality, feeling of use, etc. It was confirmed that the evaluations such as the feeling of use when rinsing the cosmetics and the feeling after use were remarkably superior to the comparative example using the foam cosmetic additive consisting only of honey.

<Test Example 6: Evaluation of foaming and foam quality when soap is used as the foam cosmetic>
Each foam cosmetic additive in the “Preparation of foam cosmetic additive” column and a commercial foam cosmetic were mixed and foamed, and then sensory evaluation was performed on foaming and foam quality. As a commercially available foamy cosmetic, soap (component: soap base, (additive soap for soap bubble bath: manufactured by soap bubble soap)) was used. As a control, a soap that was not mixed with the foam cosmetic additive was used. As comparative examples, those in which the additive for foamed cosmetics was composed only of honey and those in which the additive for foamed cosmetics was composed only of γPGA (average molecular weight: 2000 kDa) were used.

After 0.6 g of each foam cosmetic additive was added to the soap, the soap was foamed for 1 minute according to a conventional method using a foaming net (CAC Cosmetics Co., Ltd.). At the time of foaming, panelists (10 persons) judged whether the ease of foaming, the amount of foam, the fineness of foam, the elasticity of foam, and the adhesion of foam were better than the control. Based on the judgment of each panel, the result of sensory evaluation was determined according to the following criteria. The results are shown in Table 7.
◎: More than 8 people answered that it was better than control ○: More than 6 people answered that it was better than control △: More than 4 people answered that it was better than control ×: Less than 6 people Less than 4 people answered better

表７に示されるように、蜂蜜とγＰＧＡから泡状化粧料用添加剤を構成した場合、特に平均分子量が２０００〜５０００ｋＤａの範囲において、蜂蜜のみ又はγＰＧＡのみから泡状化粧料用添加剤を構成した比較例と比べて、優れた泡立ち及び泡質の向上効果が認められた。一方、蜂蜜のみ又はγＰＧＡのみから泡状化粧料用添加剤を構成した比較例の場合、泡立ち及び泡質の評価はコントロールと変わらない又はコントロールより劣る傾向にあることが確認された。

As shown in Table 7, when the foam cosmetic additive is composed of honey and γPGA, the foam cosmetic additive is composed only of honey or γPGA, particularly in the range of 2000 to 5000 kDa in average molecular weight. Compared to the comparative example, excellent foaming and foam quality improvement effects were observed. On the other hand, in the case of the comparative example in which the additive for foamy cosmetics was composed only of honey or γPGA, it was confirmed that the evaluation of foaming and foam quality was not different from the control or inferior to the control.

<Test Example 7: Evaluation of foaming and foam quality when shampoo is used as foamy cosmetics>
After each foam cosmetic additive in the above-mentioned "Preparation of foam cosmetic additive" column and a commercially available foam cosmetic were mixed, sensory evaluation was performed on foaming and foam quality. The shampoo shown in Table 8 was used as a commercially available foam cosmetic. As a control, a shampoo that was not mixed with the foam cosmetic additive was used. As comparative examples, those in which the additive for foamed cosmetics was composed only of honey and those in which the additive for foamed cosmetics was composed only of γPGA (average molecular weight: 2000 kDa) were used.

After adding 0.6 g of each foam cosmetic additive to 3.0 g of shampoo, the shampoo was foamed on the palm. At the time of foaming, panelists (10 persons) judged whether the foaming was easy, the amount of foam, the fineness of the foam, and the slipping feeling during use (as per finger) was better than the control. Based on the judgment of each panel, the result of sensory evaluation was determined according to the following criteria. The results are shown in Table 9.
◎: More than 8 people answered that it was better than control ○: More than 6 people answered that it was better than control △: More than 4 people answered that it was better than control ×: Less than 6 people Less than 4 people answered better

表９に示されるように、蜂蜜とγＰＧＡから泡状化粧料用添加剤を構成した場合、特に平均分子量が２０００〜５０００ｋＤａの範囲において、蜂蜜のみ又はγＰＧＡのみから泡状化粧料用添加剤を構成した比較例と比べて、優れた泡立ち及び泡質の向上効果が認められた。一方、蜂蜜のみ又はγＰＧＡのみから泡状化粧料用添加剤を構成した比較例の場合、泡立ち及び泡質の評価はコントロールと変わらない又はコントロールより劣る傾向にあることが確認された。

As shown in Table 9, when the foam cosmetic additive is composed of honey and γPGA, the foam cosmetic additive is composed only of honey or γPGA, particularly in the range of 2000 to 5000 kDa in average molecular weight. Compared to the comparative example, excellent foaming and foam quality improvement effects were observed. On the other hand, in the case of the comparative example in which the additive for foamy cosmetics was composed only of honey or γPGA, it was confirmed that the evaluation of foaming and foam quality was not different from the control or inferior to the control.

<Test Example 8: Evaluation of foam elasticity, foaming and foam quality when a part of honey is replaced with sugars other than honey or glycerin>
Each honey mixture was prepared by mixing fructose dextrose liquid sugar or glycerin as a substitute component in the ratio shown in Table 10 to the honey whose false acacia is a honey source plant. Foam cosmetic additives were prepared by adding 0.1% each of γPGA (BioLeaders) having an average molecular weight of 2000 kDa to the honey mixture. The foam cosmetic additive 0.6 g and the foam cosmetic B 0.6 g were foamed by stirring with a foaming ball. About the elasticity of the foam of each foamy cosmetic after foaming, the time required for the 1 yen coin to contact the plate after placing 1 yen coin (1 g) on the foam as in Example 1. Was evaluated by measuring. Table 10 shows the relative value (average value) when the time when only foamed cosmetic B as a control is foamed is 100.

In addition, for each foam cosmetic after foaming, whether panelists (10 persons) are better than controls for foaming ease, amount of foam, fineness of foam, foam elasticity, and foam adhesion Judged about. The results of sensory evaluation were determined according to the following criteria from the judgment of each panel. The results are shown in Table 11.
◎: More than 8 people answered that it was better than control ○: More than 6 people answered that it was better than control △: More than 4 people answered that it was better than control ×: Less than 6 people Less than 4 people answered better

表１０に示されるように、蜂蜜の一部を蜂蜜以外の糖類又はグリセリンに置換して泡状化粧料用添加剤を構成した場合、置換成分の割合が５０質量％であっても優れた泡の弾力性が得られることが確認された。また、表１１に示されるように、泡立ち及び泡質の官能評価においても、置換成分の割合が５０質量％であっても、優れた泡立ち及び泡質が得られることが確認された。

As shown in Table 10, when a part of honey is substituted with sugars other than honey or glycerin to constitute an additive for foamy cosmetics, excellent foam even if the ratio of the substituted component is 50% by mass It was confirmed that the elasticity of Moreover, as Table 11 shows, even in the sensory evaluation of foaming and foam quality, it was confirmed that excellent foaming and foam quality were obtained even when the ratio of the substitution component was 50% by mass.

<Test Example 9: Examination of mixing ratio of honey and γPGA>
Foaming and foam quality were evaluated when the blending ratio of honey and γPGA in the foam cosmetic additive was changed. 0.05 mass% (mass ratio of the content of honey to the content of γPGA: 1999), 0.1 mass of γPGA (manufactured by BioLeaders Co., Ltd.) having an average molecular weight of 2000 kDa, % (Same mass ratio: 999), 0.3 mass% (same mass ratio: 332), 0.5 mass% (same mass ratio: 199), and 1.3 mass% (same mass ratio: 76) are added respectively. did. And each additive for foamy cosmetics was produced by stirring overnight.

The mixing property and foaming at the time of mixing each foam cosmetic additive and commercially available foam cosmetic were evaluated. Foam cosmetic B or C was used as a commercially available foam cosmetic. 0.6 g of each foam cosmetic additive and 0.6 g of foam cosmetic B or C were taken on the palm and foamed by rubbing the palm together. As a control, a foam cosmetic B or C that was not mixed with an additive for foam cosmetic was used. At the time of foaming, it was judged whether the panelists (10 persons) were better than the control in terms of ease of foaming and mixing. The evaluation of the mixing property was performed from the viewpoint of whether the mixing property and the handling property are reduced due to gelation of the solution when the foam cosmetic additive and the foam cosmetic B or C are mixed. . The results of sensory evaluation were determined according to the following criteria from the judgment of each panel. The results are shown in Table 12. “Mass ratio of honey” in the table indicates the mass ratio of the honey content to the γPGA content.
◎: More than 8 people answered that it was better than control ○: More than 6 people answered that it was better than control △: More than 4 people answered that it was better than control ×: Less than 6 people Less than 4 people answered better

表１２に示されるように、泡状化粧料用添加剤中におけるγＰＧＡの配合量が０．０５質量％未満の場合、泡立ちが不十分となる傾向があることが確認された。γＰＧＡの配合量が０．５質量％以上では溶液がゲル化する傾向にある。それにより、混合性が低下するとともに、泡吐出用容器等を用いて使用する場合は、容器への充填が困難になり、ノズルが詰まる等、取り扱い性が低下するおそれがあることが確認された。

As shown in Table 12, it was confirmed that foaming tends to be insufficient when the blending amount of γPGA in the foam cosmetic additive is less than 0.05% by mass. When the blending amount of γPGA is 0.5% by mass or more, the solution tends to gel. As a result, it has been confirmed that the mixing property is lowered, and when using a foam discharge container or the like, it becomes difficult to fill the container, and the nozzle may be clogged or the handling property may be lowered. .

<Test Example 10: Examination of blending ratio of foam cosmetic additive and foam cosmetic>
Foaming and foam quality were evaluated when the mixing ratio of the foam cosmetic additive and foam cosmetic was changed. Foam cosmetic additives containing honey and γPGA (average molecular weight 2000 kDa) and a commercial foam cosmetic were mixed at a predetermined ratio, and then foaming was evaluated during foaming. As commercially available foam cosmetics, foam cosmetics A, B, and C shown in Table 1 were used. The foaming method followed the method of Test Example 1. In addition, each foam cosmetic which is not mixed with the additive for foam cosmetics was used as control. About the foam cosmetic after foaming, it was judged whether a panelist (10 persons) was better than each control about foaming ease. The results of sensory evaluation were determined according to the following criteria from the judgment of each panel. The results are shown in Table 13.
