Description
本発明は皮膚化粧料に関する。 The present invention relates to a skin cosmetic.
従来から、塗布後に清涼感やさらさら感を与えるための化粧料として、水やアルコール等の液体中に粉体を含有する2層型の化粧料が知られている(特許文献1及び特許文献2)。このような2層型の化粧料は静置した状態では2層に分離しているため、使用直前に化粧料を入れた容器を振とうして粉体を化粧料全体に分散させた後、身体に塗布する。従って、このような化粧料には、塗布後の速乾性や清涼感、さらさら感を与える特性が優れているだけではなく、振とう時に容易に粉体が分散する特性(「再分散性」と称する場合がある。)にも優れていることが求められている。 2. Description of the Related Art Conventionally, as a cosmetic for giving a refreshing feeling or a smooth feeling after application, a two-layer cosmetic containing a powder in a liquid such as water or alcohol is known (Patent Document 1 and Patent Document 2). ). Since such a two-layer cosmetic is separated into two layers when left standing, after the powder is dispersed throughout the cosmetic by shaking the container containing the cosmetic just before use, Apply to the body. Therefore, such cosmetics are not only excellent in properties that give quick drying after application, a refreshing sensation, and a smooth sensation, but also easily disperse the powder when shaken (“redispersibility”). It is also required to be excellent.
上記の速乾性や清涼感を高めるためには、粉体を含有させる液体として高濃度のエタノールを使用することが有効であるが、その場合には、粉体が凝集して固化しやすくなり、再分散性が低下するという問題がある。かかる問題を軽減するために、ポリオキシエチレンアルキルエーテルリン酸を配合した技術(特許文献3)や、有機酸及び/又はその塩を配合した技術(特許文献4)、ノニオン界面活性剤を配合した技術(特許文献5)及び水溶性アルミニウム塩を配合した技術(特許文献6)が知られている。 In order to enhance the above-mentioned quick-drying and refreshing feeling, it is effective to use high-concentration ethanol as the liquid containing the powder, but in that case, the powder tends to aggregate and solidify, There is a problem that the redispersibility is lowered. In order to alleviate such a problem, a technique (Patent Document 3) containing polyoxyethylene alkyl ether phosphoric acid, a technique (Patent Document 4) containing an organic acid and / or a salt thereof, and a nonionic surfactant were added. A technique (Patent Document 5) and a technique (Patent Document 6) containing a water-soluble aluminum salt are known.
しかしながらこのような先行技術では、再分散性はいくぶん改善されるものの、未だ十分とは言えない。 However, with such prior art, although redispersibility is somewhat improved, it is still not sufficient.
従って、本発明の課題は、高い速乾性、清涼感やさらさら感を有しながら、さらに優れた再分散性を有する皮膚化粧料を提供することにある。 Therefore, the subject of this invention is providing the skin cosmetics which have the further excellent redispersibility, having high quick-drying property, a refreshing feeling, and a smooth feeling.

The pH of the skin cosmetic can be adjusted by adding an acid or alkali as appropriate.
本発明の皮膚化粧料は、比較的高濃度のエタノールを含んでいる。これにより、皮膚化粧料を塗布した後の速乾性に優れ、さらに高い清涼感を付与することができる。さらに、ポリエチレン末及びナイロン末を含むことにより、さらさら感を付与することができる。
しかしながら、一般的に、粉体を含む皮膚化粧料において、エタノール濃度を高くした場合には、保存時に粉体が凝集しやすくなり、使用時の粉体の再分散性が低下する問題があった。
The skin cosmetic of the present invention contains a relatively high concentration of ethanol. Thereby, it is excellent in quick-drying after apply | coating skin cosmetics, and can provide a still higher refreshing feeling. Furthermore, a smooth feeling can be provided by including polyethylene powder and nylon powder.
However, in general, in skin cosmetics containing powder, when the ethanol concentration is increased, the powder tends to aggregate during storage, and the redispersibility of the powder during use is reduced. .
これに対して、本発明者らは、ポリエチレン末とナイロン末を併用することによって、高濃度のエタノール存在下においても、粉体の再分散性が飛躍的に向上することを見出し、本発明を完成した。このように粉体の再分散性が向上するメカニズムとしては、詳細は不明であるが、ポリエチレン末とナイロン末とを併用することによって、ポリエチレン末とナイロン末が集合体を形成し、この集合体が疎な状態で集積するため穏やかな振とうによっても容易に再分散するものと推測される。 In contrast, the present inventors have found that by using polyethylene powder and nylon powder in combination, the redispersibility of the powder is greatly improved even in the presence of a high concentration of ethanol. completed. As the mechanism for improving the redispersibility of the powder in this way, the details are unknown, but by using polyethylene powder and nylon powder together, the polyethylene powder and nylon powder form an aggregate, and this aggregate Are accumulated in a sparse state, so it is assumed that they can be easily re-dispersed by gentle shaking.
なお、電解質を添加した場合には、ポリエチレン末とナイロン末とによる集合体がより形成されやすくなり、再分散性がより一層向上するため好ましい。 In addition, it is preferable to add an electrolyte because an aggregate of polyethylene powder and nylon powder is more easily formed and redispersibility is further improved.
なお、後述の実施例で示されるように、シリカ末、ポリスチレン末及びタルクの組み合わせでは再分散性は向上しなかったことから、本発明においては、ポリエチレン末とナイロン末とが必須の粉体であり、しかも両者の質量比を特定の範囲に限定することによって、上記再分散性の向上効果が発揮される。 As shown in the examples below, the combination of silica powder, polystyrene powder and talc did not improve redispersibility, so in the present invention, polyethylene powder and nylon powder are essential powders. In addition, by limiting the mass ratio of both to a specific range, the effect of improving the redispersibility is exhibited.
本発明の皮膚化粧料は、例えば化粧水であることが好ましい。また、上記化粧水である本発明の皮膚化粧料を、不織布などのシート基材に含浸させることによって、シート化粧料として使用することもできる。 The skin cosmetic of the present invention is preferably a lotion, for example.

一方、粉体としてナイロン末のみ(比較例1)及びポリエチレン末のみ(比較例2)の組成では、再分散性が劣ることが分かった。なお、比較例2及び比較例5では、粉体が液体成分の上層に浮かんでいた。この状態は安定性の観点から好ましくないため、本例の再分散性は×(不良)と判定した(*1)。 On the other hand, it was found that the redispersibility was inferior with the composition of only the nylon powder (Comparative Example 1) and the polyethylene powder (Comparative Example 2) as the powder. In Comparative Examples 2 and 5, the powder floated on the upper layer of the liquid component. Since this state is not preferable from the viewpoint of stability, the redispersibility of this example was determined to be x (defective) (* 1).
エタノールの量が少ない組成(比較例3)では、速乾性の点で劣っていた。ナイロン末とポリエチレン末との質量比が本発明の範囲外の組成(比較例4及び5)では、再分散性に劣り、ポリエチレン末の割合が低い組成(比較例4)では塗布後のさらさら感にも劣っていた。ナイロン末とポリエチレン末との合計含有量が本発明の範囲外の組成(比較例6及び7)では、さらさら感に劣っているか、又は白化の点で劣っていた。さらに、ナイロン末とポリエチレン末との組み合わせに代えて、化粧料の分野で広く用いられている粉体のシリカ末、ポリスチレン末又はタルクと組み合わせてみても、再分散性は向上しなかった。このことから、エタノール濃度が比較的高い化粧料において、粉体としてナイロン末とポリエチレン末とを使用するという組み合わせによる再分散性の向上効果は特異的なものであることが示唆された。 The composition with a small amount of ethanol (Comparative Example 3) was inferior in terms of quick drying. In compositions where the mass ratio of nylon powder to polyethylene powder is outside the range of the present invention (Comparative Examples 4 and 5), redispersibility is poor, and in compositions where the ratio of polyethylene powder is low (Comparative Example 4), the smooth feeling after coating It was also inferior. When the total content of the nylon powder and the polyethylene powder was outside the range of the present invention (Comparative Examples 6 and 7), the dry feeling was inferior or the whitening was inferior. Furthermore, redispersibility was not improved even when combined with powdered silica powder, polystyrene powder or talc, which are widely used in the cosmetics field, instead of the combination of nylon powder and polyethylene powder. This suggests that the effect of improving redispersibility by a combination of using nylon powder and polyethylene powder as a powder is unique in cosmetics having a relatively high ethanol concentration.
なお、エタノールが95.0質量%の組成の皮膚化粧料を調製したが、皮膚への刺激が強すぎたため、化粧料としての使用はできないと判断した。 In addition, although the skin cosmetics of the composition whose ethanol is 95.0 mass% was prepared, since irritation | stimulation to skin was too strong, it was judged that the use as cosmetics cannot be performed.
