Description

本発明は、皮膚への負担がより大きい合成界面活性剤を使用せず、脂肪酸石鹸のみで、ポンプフォーマーから容易にきめ細かで弾力性に富み壊れにくい泡が得られ、低温で保存しても起泡性が損なわれず,低温でも起泡する起泡性洗浄料に関する。   The present invention does not use a synthetic surfactant that places a heavy burden on the skin, and only a fatty acid soap can provide a foam that is easily fine, elastic and hard to break from a pump former, and can be stored at low temperatures. The present invention relates to a foaming detergent that does not impair foaming properties and foams even at low temperatures.

ポンプフォーマーを用いて使用時に洗浄料を泡立て、その泡で皮膚を洗浄する起泡性洗浄料は、洗浄時に手指などで直接皮膚を摩擦することが少なく、また、適度な洗浄力を持つために、皮膚への負担が少ない洗浄料として好まれる。一般に洗浄料に多用される非イオン系界面活性剤などの合成界面活性剤が、タンパク変性作用などを有することから、合成界面活性剤を使用せず、タンパク変性作用などの少ない脂肪酸石鹸を使用した起泡性洗浄料が好まれる。例えば、特許文献1には、脂肪酸石鹸系洗顔クリームが提案されている。しかしながら、一般に脂肪酸石鹸を使用した洗浄料は起泡性に劣り、低温での保存などが困難である。合成界面活性剤を使用せず、脂肪酸石鹸のみの洗浄料において、ポンプフォーマーから容易に、きめ細かで弾力性に富み、壊れにくい泡が得られ、低温でも起泡する起泡性洗浄料はこれまで知られていなかった。   Foaming detergents that use a foam former to lather the detergent when used and clean the skin with the foam are less likely to rub the skin directly with fingers during washing, and have an appropriate detergency. In addition, it is preferred as a cleaning agent that has a low burden on the skin. Synthetic surfactants such as non-ionic surfactants commonly used in detergents have protein denaturing action, etc. Therefore, synthetic surfactants are not used and fatty acid soaps with little protein denaturing action are used. Foaming detergents are preferred. For example, Patent Literature 1 proposes a fatty acid soap face-wash cream. However, in general, a detergent using a fatty acid soap is inferior in foaming properties and is difficult to store at a low temperature. This is a foaming detergent that does not use synthetic surfactants and is a fatty acid soap-only detergent that produces foam that is easily fine, elastic, and hard to break, and foams even at low temperatures. It was not known until.

The weight ratio of the total weight of myristic acid and lauric acid to the total weight of palmitic acid and stearic acid is 1.0-26.
It is characterized by being.
The foaming detergent having the above-described structure has a feature that a foamer can be easily obtained from a pump former without any use of a synthetic surfactant. .

本発明の起泡性洗浄料において、前記洗浄料の多価アルコールがグリセリン、1,3−ブチレングリコールからなる群より選ばれる1種もしくは2種以上であることが好ましい。
グリセリン、1,3−ブチレングリコールは起泡性洗浄料の泡質をより豊かにし、洗浄後の皮膚の突っ張り感が軽減される効果に優れる。
In the foamable cleaning material of the present invention, the polyhydric alcohol of the cleaning material is preferably one or more selected from the group consisting of glycerin and 1,3-butylene glycol.
Glycerin and 1,3-butylene glycol enrich the foam quality of the foaming detergent and are excellent in the effect of reducing the feeling of skin tension after washing.

本発明の起泡性洗浄料は、合成界面活性剤を使用せず、脂肪酸石鹸のみで、ポンプフォーマーから容易に、きめ細かで弾力性に富み、壊れにくい泡が得られ、低温でも起泡するため、洗浄時に手指などで直接皮膚を摩擦することが少なく、また、適度な洗浄力を持つために、皮膚への負担が少ない。さらに、一般に洗浄料に多用される非イオン系界面活性剤などの合成界面活性剤を使用していないため、タンパク変性作用などの有害作用が少ない。   The foaming detergent according to the present invention does not use a synthetic surfactant, and only a fatty acid soap. From a pump former, a foam that is fine, elastic, and hard to break can be obtained, and foams even at low temperatures. For this reason, the skin is hardly rubbed directly with fingers during washing, and since it has an appropriate washing power, the burden on the skin is small. In addition, since synthetic surfactants such as nonionic surfactants commonly used in detergents are not used, there are few harmful effects such as protein denaturation.

The foamable cleaning material of the present invention is based on the total amount of cleaning material,
(1) 1.4 to 4.6% by weight of a total fatty acid composed of lauric acid, myristic acid, palmitic acid and stearic acid,
(2) 0.2 to 1.7% by weight of lauric acid, 0.5 to 2.7% by weight of myristic acid, 0.05 to 0.9% by weight of palmitic acid, and 0.05 to 0 of stearic acid 9% by weight,
(3) Potassium hydroxide as an alkaline agent is 95 to 105 mol% based on the total amount of total fatty acids, or at least one of monoethanolamine and diethanolamine as an alkaline agent is 90 to 105 mol% with respect to the total amount of total fatty acids,

The weight ratio of the total weight of myristic acid and lauric acid to the total weight of palmitic acid and stearic acid ((weight of myristic acid + weight of lauric acid) / (weight of palmitic acid + stearic acid) Weight)) is 1.0-26
And foam using a pump former.

本発明の起泡性洗浄料において、総脂肪酸の配合比は起泡性洗浄料の全量に対して1.4〜4.6重量%が好ましい。1.4重量%以下であると、きめ細かで弾力性に富み壊れにくい泡が得られなくなるおそれがあり、4.6重量%以上であると、ポンプフォーマーから泡が出なくなるおそれがある。   In the foamable detergent of the present invention, the blending ratio of total fatty acids is preferably 1.4 to 4.6% by weight with respect to the total amount of the foamable detergent. If it is 1.4% by weight or less, it is likely that a fine, elastic, and foam-resistant foam cannot be obtained, and if it is 4.6% by weight or more, foam may not be produced from the pump former.

ラウリル酸の配合比は起泡性洗浄料の全量に対して0.2〜1.7重量%が好ましい。0.2重量%以下であると、きめ細かで弾力性に富み壊れにくい泡が得られなくなるおそれがあり、1.7重量%以上であると、ポンプフォーマーから泡が出なくなったり、低温安定性が悪くなるおそれがある。   The blending ratio of lauric acid is preferably 0.2 to 1.7% by weight with respect to the total amount of the foaming detergent. If it is less than 0.2% by weight, it may not be possible to obtain a fine, resilient and hard-to-break foam. If it is more than 1.7% by weight, it will not be generated from the pump former, or it may be stable at low temperatures. May get worse.

ミリスチン酸の配合比は起泡性洗浄料の全量に対して0.5〜2.7が好ましい。0.5重量%以下であると、きめ細かで弾力性に富み壊れにくい泡が得られなくなるおそれがあり、2.7重量%以上であると、ポンプフォーマーから泡が出なくなるおそれがある。   The blending ratio of myristic acid is preferably 0.5 to 2.7 with respect to the total amount of the foaming detergent. If it is 0.5% by weight or less, there is a risk that it is difficult to obtain a fine foam that is highly elastic and hard to break. If it is 2.7% by weight or more, there is a possibility that the foam does not come out from the pump former.

ミリスチン酸とラウリル酸の重量比(ミリスチン酸の重量/ラウリル酸の重量)は0.5〜6.0が好ましい。0.5以下であると、きめ細かで弾力性に富み壊れにくい泡が得られなくなるおそれがあり、6.0以上であると、ポンプフォーマーから泡が出なくなったり、低温安定性が悪くなるおそれがある。   The weight ratio of myristic acid and lauric acid (weight of myristic acid / weight of lauric acid) is preferably 0.5 to 6.0. If it is 0.5 or less, there is a risk that it will be difficult to obtain a fine, resilient and hard-to-break foam. If it is 6.0 or more, foam may not be produced from the pump former or low-temperature stability may be deteriorated. There is.

パルミチン酸とステアリン酸の重量比(パルミチン酸の重量/ステアリン酸の重量)は0.05〜8.0が好ましい。0.05以下であると、きめ細かで弾力性に富み壊れにくい泡が得られなくなるおそれがあり、8.0以上であると、ポンプフォーマーから泡が出なくなるおそれがある。   The weight ratio of palmitic acid to stearic acid (the weight of palmitic acid / the weight of stearic acid) is preferably 0.05 to 8.0. If it is 0.05 or less, there is a possibility that it is difficult to obtain a fine foam having high elasticity and hardly breaks, and if it is 8.0 or more, there is a possibility that the foam does not come out from the pump former.

ミリスチン酸とラウリル酸の合計重量とパルミチン酸とステアリン酸の合計重量の重量比((ミリスチン酸の重量+ラウリル酸の重量)/(パルミチン酸の重量+ステアリン酸の重量))は1.0〜26が好ましい。1.0以下であると、きめ細かで弾力性に富み壊れにくい泡が得られなくなるおそれがあり、26以上であると、ポンプフォーマーから泡が出なくなるおそれがある。   The weight ratio of the total weight of myristic acid and lauric acid and the total weight of palmitic acid and stearic acid ((weight of myristic acid + weight of lauric acid) / (weight of palmitic acid + weight of stearic acid)) is 1.0 to 26 is preferred. If it is 1.0 or less, there is a possibility that it is difficult to obtain a fine foam that is highly elastic and hard to break. If it is 26 or more, there is a possibility that the foam does not come out from the pump former.

脂肪酸を中和するためのアルカリ剤としては、水酸化カリウム、モノエタノールアミン、ジエタノールアミンが好ましく、これらの一種または二種以上が使用できる。水酸化カリウムとジエタノールアミンが泡質や低温での起泡性などにすぐれるため、より好ましい。アルカリ剤の配合比は、水酸化カリウムの場合、総脂肪酸の全量に対して95〜105モル%が好ましい。95モル%以下であると、洗浄力と、室温並びに低温での起泡性が低下するおそれがある。105モル%以上であると、洗浄料のアルカリ性が強すぎて皮膚刺激性などが出るおそれがある。
アルカリ剤がモノエタノールアミンとジエタノールアミンの少なくとも一方である場合は、アルカリ剤の配合比は、総脂肪酸の全量に対して90〜105モル%が好ましい。90モル%以下であると、洗浄力と、室温並びに低温での起泡性が低下するおそれがある。105モル%以上であると、洗浄料のアルカリ性が強すぎて皮膚刺激性などが出るおそれがある。
本発明の起泡性洗浄料において、アルカリ剤として水酸化カリウムを使用した場合に得られる洗浄料は、洗浄後の皮膚が比較的さっぱりとした感触が得られる。一方、アルカリ剤としてモノエタノールアミンとジエタノールアミンの少なくとも一方を使用した場合に得られる洗浄料は、洗浄後の皮膚が比較的しっとりとした感触が得られる。したがって、これらのアルカリ剤を適宜組み合わせることにより、所望の洗い上がり感を持つ起泡性洗浄料が得られる。
As the alkaline agent for neutralizing the fatty acid, potassium hydroxide, monoethanolamine, and diethanolamine are preferable, and one or more of these can be used. Potassium hydroxide and diethanolamine are more preferable because they are excellent in foam quality and foamability at low temperatures. In the case of potassium hydroxide, the blending ratio of the alkaline agent is preferably 95 to 105 mol% with respect to the total amount of total fatty acids. If it is 95 mol% or less, the detergency and foaming properties at room temperature and low temperature may be reduced. If it is 105 mol% or more, the alkalinity of the cleaning agent may be too strong, and skin irritation may occur.
When the alkaline agent is at least one of monoethanolamine and diethanolamine, the blending ratio of the alkaline agent is preferably 90 to 105 mol% with respect to the total amount of total fatty acids. If it is 90 mol% or less, the detergency and foaming properties at room temperature and low temperature may be reduced. If it is 105 mol% or more, the alkalinity of the cleaning agent may be too strong, and skin irritation may occur.
In the foamable cleaning material of the present invention, the cleaning material obtained when potassium hydroxide is used as the alkali agent provides a relatively refreshing feel to the skin after cleaning. On the other hand, the cleaning agent obtained when at least one of monoethanolamine and diethanolamine is used as the alkaline agent provides a relatively moist feel to the skin after cleaning. Therefore, by appropriately combining these alkali agents, a foaming detergent having a desired feeling of washing can be obtained.

本発明の起泡性洗浄料は、アルギン酸ナトリウムとペクチンの少なくとも一方の酸性多糖体を含むことにより、弾力性に富み、壊れにくい泡が得られ、皮膚を洗浄した後の突っ張り感が軽減される。酸性多糖体の配合比は、洗浄料の全量に対して0.05〜0.3重量%が好ましい。0.05重量%以下であると、泡の弾力性が弱くなり、皮膚を洗浄した後の突っ張り感の軽減が弱くなるおそれがあり、0.3重量%以上であると、ポンプフォーマーから泡が出にくくなるおそれがある。   The foaming cleansing agent of the present invention contains at least one acidic polysaccharide of sodium alginate and pectin, so that it is highly elastic and a foam that is hard to break is obtained, and the feeling of tension after washing the skin is reduced. . The compounding ratio of the acidic polysaccharide is preferably 0.05 to 0.3% by weight with respect to the total amount of the cleaning material. If it is 0.05% by weight or less, the elasticity of the foam is weakened, and there is a possibility that the reduction of tension after washing the skin may be weakened. May be difficult to get out.

前記本発明の起泡性洗浄料は、多価アルコールを含むことにより、泡質がより豊かになり、洗浄後の皮膚の突っ張り感が軽減される。多価アルコールとしては、グリセリン、1,3−ブチレングリコールが好ましく、これらの1種もしくは2種以上が使用できる。多価アルコールの配合比は洗浄料の全量に対して3〜30重量%が好ましい。3重量%以下では、泡質をより豊かにし、皮膚を洗浄した後の突っ張り感を軽減する効果が得られないおそれがあり、30重量%以上では、ポンプフォーマーから泡が出なくなるおそれがある。   When the foamable cleaning material of the present invention contains polyhydric alcohol, the foam quality becomes richer and the feeling of skin tension after cleaning is reduced. As the polyhydric alcohol, glycerin and 1,3-butylene glycol are preferable, and one or more of these can be used. The blending ratio of the polyhydric alcohol is preferably 3 to 30% by weight with respect to the total amount of the cleaning material. If it is 3% by weight or less, there is a possibility that the foam quality will be richer and the effect of reducing the feeling of tension after washing the skin may not be obtained, and if it is 30% by weight or more, foam may not be generated from the pump former. .

本発明の起泡性洗浄料は、本発明の効果を損なわない範囲で、通常使用される成分、例えば、乳糖、マンニトール、キシリトール、グルコース、シュークロース、マルトース等の糖類、香料、色素、エモリエント剤、殺菌剤、美白剤、防腐剤、酸化防止剤等を適宜配合することができる。   The foaming detergent of the present invention is a component that is usually used, for example, sugars such as lactose, mannitol, xylitol, glucose, sucrose, maltose, fragrances, pigments, emollients, as long as the effects of the present invention are not impaired. , Fungicides, whitening agents, preservatives, antioxidants and the like can be appropriately blended.

実施例1〜33までの起泡性洗浄料及び比較例1〜15までの洗浄料をそれぞれ容量100mlの手動式ポンプフォーマーに入れ、2プッシュ分をプラスティックトレーの上に吐出し、1時間、2時間放置後の泡の状態を目視で判定した。判定基準は、◎:2時間放置後でも泡の状態に変化はない、○: 2時間放置後、若干泡の量は減少しているが、十分な量が残っている、△: 2時間放置後、泡量の減少は顕著だが、残っている、×:放置後1時間以降2時間以内に泡は消滅、××:放置後1時間以内に泡は消滅、の5段階とした。
Evaluation 3: Sustainability of foam The foaming detergents of Examples 1 to 33 and the detergents of Comparative Examples 1 to 15 were put in a manual pump former having a capacity of 100 ml, and 2 pushes were placed on the plastic tray. The state of bubbles after being discharged for 1 hour and 2 hours was visually judged. Judgment criteria are: ◎: No change in foam state even after standing for 2 hours, ○: After 2 hours, the amount of foam is slightly reduced, but a sufficient amount remains, △: Left for 2 hours After that, although the decrease in the amount of foam was remarkable, it was classified into 5 stages: remaining: X: bubbles disappeared within 2 hours after 1 hour after standing, and XX: bubbles disappeared within 1 hour after standing.

評価4:室温での発泡性
実施例1〜33までの起泡性洗浄料及び比較例1〜15までの洗浄料をそれぞれ容量100mlの手動式ポンプフォーマーに入れ、2プッシュ分をプラスティックトレーの上に吐出した時の状態を目視で判定した。判定基準は、○:安定に発泡する、×:安定に発泡しない(ポンプフォーマーから吐出できない)、の2段階とした。
Evaluation 4: Foamability at room temperature The foaming detergents of Examples 1 to 33 and the detergents of Comparative Examples 1 to 15 were each put into a manual pump former having a capacity of 100 ml, and 2 pushes were placed on the plastic tray. The state when discharged upward was judged visually. The judgment criteria were two stages: ○: foaming stably, x: foaming stably (cannot be discharged from the pump former).

評価5:低温での発泡性
5℃の冷温庫で2時間保管した実施例1〜33までの起泡性洗浄料及び比較例1〜15までの洗浄料をそれぞれ容量100mlの手動式ポンプフォーマーに入れ、2プッシュ分をプラスティックトレーの上に吐出し、目視で判定した。判定基準は、○:安定に発泡する、×:安定に発泡しない(ポンプフォーマーから吐出できない、または吐出された泡の状態が著しく劣化している)、の2段階とした。
Evaluation 5: Foaming property at low temperature Manual pump former having a capacity of 100 ml each of the foaming cleaning materials up to Examples 1 to 33 and the cleaning materials up to Comparative Examples 1 to 15 stored in a cold storage at 5 ° C. for 2 hours. 2 pushes were ejected onto a plastic tray and visually judged. Judgment criteria were two stages: ◯: foaming stably, x: not foaming stably (cannot be discharged from the pump former, or the state of the discharged foam is significantly deteriorated).

評価結果
表1と表2から明らかなように、本発明の起泡性洗浄料は、ポンプフォーマーから容易にきめ細かで弾力性に富み壊れにくい泡が得られ、低温でも起泡することが明らかである。特に、実施例2の起泡性洗浄料が、泡質が非常に優れていた。また、表には記載していないが、本発明の起泡性洗浄料は、洗顔に使用した場合、比較例の洗浄料に対して洗顔後の皮膚のつっぱり感などが少なく、また、減少した皮膚の油分量の回復にも優れていた。
Evaluation Results As is clear from Tables 1 and 2, the foaming detergent of the present invention can easily produce fine foams that are highly elastic and resistant to breakage from the pump former, and it is clear that foaming occurs even at low temperatures. It is. In particular, the foamable cleaning material of Example 2 was very excellent in foam quality. Further, although not listed in the table, the foaming detergent of the present invention, when used for washing the face, has less and less feeling of skin tightness after washing the face compared to the comparative washing agent. It was also excellent in recovering the oil content of the skin.

本発明により,合成界面活性剤を使用せず、脂肪酸石鹸のみで、ポンプフォーマーから容易に、きめ細かで弾力性に富み、壊れにくい泡が得られ、低温で保存しても起泡性が損なわれず,低温でも起泡する起泡性洗浄料が容易に得られる。   According to the present invention, a synthetic surfactant is not used, and only a fatty acid soap, a foam that is easily fine, elastic, and hard to break can be obtained from a pump former, and foamability is impaired even when stored at low temperatures. Therefore, a foaming detergent that foams even at low temperatures can be easily obtained.
