Abstract
Description
そこで、ウェットシート、ウェットワイパー、ウェット綿等に含浸させる清拭組成物には、繊維に吸着される分を見越して多量の防菌防黴剤が配合されている(特許文献1参照)。 When paper or a nonwoven fabric is impregnated with an aqueous solution containing an antibacterial / antifungal agent, most of the antibacterial / antifungal agent is adsorbed onto the fibers. Specifically, about 80% of N-coconut oil fatty acid acyl L-arginine ethyl DL pyrrolidone carboxylate and about 30% of paraoxybenzoic acid esters (parabens) are adsorbed. The fouling performance is significantly reduced.
Therefore, a large amount of antibacterial and antifungal agents are blended in the wiping composition impregnated in wet sheets, wet wipers, wet cotton, etc. in anticipation of the amount adsorbed on the fibers (see Patent Document 1).
ここで、セパシア菌(Burkholderia cepacia)は、自然環境に常在する細菌であり、カチオン性界面活性剤に耐性を有する。また、CTFA Microbiology Guidelinesにもチャレンジテストの評価菌の一つとして記載されている。
また、低温安定性を向上させることを目的として、(C)多価アルコールを配合すること、更に、不織布の素材として拭き取り性においてコシのある疎水性繊維と、肌触りの良好な親水性繊維とを用い、その質量比率(親水性繊維/疎水性繊維)を90/10~50/50とすることにより、肌触りがよく、拭き取り性が良好となることを知見した。
また、本発明において「ノンアルコール」であるとは、シート状化粧料の(A)~(D)成分及び香料などから持ち込まれるエタノールを実質的に含まないことを意味する。このようなノンアルコールタイプのシート状化粧料は、従来の皮膚刺激性(ピリピリ感)のあるアルコールタイプのシート状化粧料と比べて、拭き取り後のさっぱり感については劣る傾向にある。そこで、本発明においては、更に(D)モモの葉エキス、ブドウ葉エキス、シラカバエキス及びハマメリスエキスから選択される少なくとも1種の植物エキスを添加することにより、アルコールを添加しなくても良好なさっぱり感を付与できることを知見した。 As a result of repeated studies by the present inventors in order to solve the above-mentioned problems, the liquid composition impregnated into the sheet-like cosmetic is a non-alcohol formulation with low irritation to the skin, and an amino acid system with high mildness to the skin Surfactant (A) N-coconut oil fatty acid acyl L-arginine ethyl DL pyrrolidone carboxylate and (B) paraoxybenzoic acid ester, mass of component (A) and component (B) The ratio [(A) / (B)] is 0.60 to 5.00, and the total content of the component (A) and the component (B) is 0.15% by mass to 0.40% by mass. Thus, it has been found that even when the liquid composition is adsorbed to the nonwoven fabric, antiseptic performance can be ensured, and in particular, the growth of Cepacia bacteria can be suppressed.
Here, the cepacia ( Burkholderia cepacia ) is a bacterium that is resident in the natural environment and has resistance to a cationic surfactant. It is also described in CTFA Microbiology Guidelines as one of the challenge test evaluation bacteria.
In addition, for the purpose of improving low temperature stability, (C) blending a polyhydric alcohol, and further, a hydrophobic fiber having a firm wiping property as a nonwoven fabric material and a hydrophilic fiber having a good touch It was found that when the mass ratio (hydrophilic fiber / hydrophobic fiber) was 90/10 to 50/50, the touch was good and the wiping property was good.
Further, in the present invention, “non-alcohol” means that it does not substantially contain ethanol brought in from the components (A) to (D) of the sheet-like cosmetic and perfume. Such non-alcohol-type sheet-shaped cosmetics tend to be inferior in terms of a refreshing feeling after wiping, as compared with conventional alcohol-type sheet-shaped cosmetics having skin irritation (feeling of tingling). Therefore, in the present invention, (D) at least one plant extract selected from peach leaf extract, grape leaf extract, birch extract and hamamelis extract may be added, so that no alcohol is added. It has been found that a refreshing feeling can be imparted.

<1> A sheet-like cosmetic comprising a nonwoven fabric impregnated with a liquid composition,
The nonwoven fabric is composed of hydrophilic fibers and hydrophobic fibers, and the mass ratio of the hydrophilic fibers to the hydrophobic fibers (hydrophilic fibers / hydrophobic fibers) is 90/10 to 50/50,
The liquid composition is
(A) N-coconut oil fatty acid acyl L-arginine ethyl DL pyrrolidone carboxylate;
(B) a paraoxybenzoic acid ester;
(C) a polyhydric alcohol,
The mass ratio [(A) / (B)] of the component (A) and the component (B) is 0.60 to 5.00, and the total content of the component (A) and the component (B) Is a sheet-like cosmetic characterized by 0.15 mass% to 0.40 mass%.

本発明のシート状化粧料は、不織布に液組成物が含浸されてなる。 (Sheet cosmetic)
The sheet-like cosmetic of the present invention is obtained by impregnating a nonwoven fabric with a liquid composition.
前記不織布は、親水性繊維と疎水性繊維とから構成される。
前記親水性繊維と前記疎水性繊維との質量比率(親水性繊維/疎水性繊維)は、90/10~50/50であり、拭き取り感や肌触りから80/20~70/30が好ましい。前記親水性繊維が、90質量%を超えると、拭き取り感が劣り、使用時にヨレやヘタリが発生しやすく、肌へのべたつき感が大きい。一方、前記親水性繊維が、50質量%未満であると、液組成物の含浸性の低下により肌触りが悪くなる。前記親水性繊維と前記疎水性繊維との質量比率(親水性繊維/疎水性繊維)が、前記好ましい範囲内であると、使用時のヨレやヘタリ、肌へのべたつき感がなく、また、液組成物をより充分に含浸させることができるために、肌を拭いたときのぬれ感や、拭き取り感により優れる点で、有利である。 <Nonwoven fabric>
The nonwoven fabric is composed of hydrophilic fibers and hydrophobic fibers.
The mass ratio of the hydrophilic fiber to the hydrophobic fiber (hydrophilic fiber / hydrophobic fiber) is 90/10 to 50/50, and is preferably 80/20 to 70/30 in view of wiping feeling and touch. When the hydrophilic fiber exceeds 90% by mass, the wiping feeling is inferior. On the other hand, when the hydrophilic fiber is less than 50% by mass, the touch of the liquid composition is deteriorated due to a decrease in impregnation property. When the mass ratio of the hydrophilic fiber to the hydrophobic fiber (hydrophilic fiber / hydrophobic fiber) is within the above preferred range, there is no twist or stickiness at the time of use, and there is no feeling of stickiness to the skin. Since the composition can be more sufficiently impregnated, it is advantageous in that it is superior in a wet feeling when wiping the skin and a feeling of wiping off.
これらの中でも、前記疎水性繊維としては、特に、熱溶融性繊維であることが好ましい。
前記熱溶融性繊維としては、加熱によって溶融し、相互に接着性を発現する繊維であれば特に制限はなく、目的に応じて適宜選択することができ、例えば、ポリエチレン、ポリプロピレン、ポリビニルアルコール等のポリオレフィン系単一繊維、ポリエチレンテレフタレート/ポリエチレン、ポリエチレンテレフタレート/ポリプロピレン、ポリプロピレン/ポリエチレン、ポリエチレンテレフタレート/エチレン-プロピレン共重合体、低融点ポリエステル-ポリエステルなどからなる鞘部分が相対的に低融点とされる芯鞘型複合繊維、サイドバイサイド型複合繊維、ポリエチレンテレフタレート/ポリプロピレン、ポリエチレンテレフタレート/ナイロン、ポリプロピレン/ポリエチレンからなる各成分の一部が表面に露出している分割型複合繊維、ポリエチレンテレフタレート/エチレン-プロピレン共重合体からなる一方の成分の熱収縮により分割する熱分割型複合繊維などを用いることができる。 There is no restriction | limiting in particular as said hydrophobic fiber, According to the objective, it can select suitably, For example, polyester fiber, such as polyolefin fiber, such as polyethylene (PE) and polypropylene (PP), polyethylene terephthalate, nylon, etc. And synthetic fibers such as polyamide fibers, polyacrylonitrile fibers, polyvinyl alcohol fibers, and polyurethane fibers. Among these, polyolefin fibers and polyester fibers are particularly preferable in terms of less twist and set.
Among these, the hydrophobic fiber is particularly preferably a heat-meltable fiber.
The heat-meltable fiber is not particularly limited as long as it is a fiber that melts by heating and exhibits adhesiveness to each other, and can be appropriately selected according to the purpose. Examples thereof include polyethylene, polypropylene, and polyvinyl alcohol. A core having a sheath having a relatively low melting point, such as a single polyolefin fiber, polyethylene terephthalate / polyethylene, polyethylene terephthalate / polypropylene, polypropylene / polyethylene, polyethylene terephthalate / ethylene-propylene copolymer, low-melting polyester-polyester Split with sheath-type conjugate fiber, side-by-side type conjugate fiber, polyethylene terephthalate / polypropylene, polyethylene terephthalate / nylon, and polypropylene / polyethylene partially exposed on the surface Composite fibers, polyethylene terephthalate / ethylene - such as heat splittable conjugate fibers which divides the heat shrinkage of the one component comprising a propylene copolymer can be used.
前記不織布としては、適宜作製したものを使用してもよいし、市販品を使用してもよい。該市販品としては、例えばAS-40(レーヨン:PP/PE(50/50)=80:20、坪量40g/m2、開孔率23%、ダイワボウポリテック株式会社製)などが挙げられる。 Each of the hydrophilic fiber and the hydrophobic fiber may be used alone or in combination of two or more. When using 2 or more types, the total mass ratio of the said hydrophilic fiber and the said hydrophobic fiber should just be in the range of an above described mass ratio.
As said nonwoven fabric, what was produced suitably may be used and a commercial item may be used. Examples of the commercially available product include AS-40 (rayon: PP / PE (50/50) = 80: 20, basis weight 40 g / m 2 , open area 23%, manufactured by Daiwabo Polytech Co., Ltd.).
なお、前記厚さは、例えば、ピーコック式厚み測定器で、直径44mmの押圧円盤を用いて、150mm×100mmの試料を、押圧2kPaのダイヤルゲージにて、各不織布の1点を10秒間放置して、測定することができる。 The thickness of the nonwoven fabric is not particularly limited and may be appropriately selected depending on the intended purpose, but is preferably 0.3 mm to 5 mm, and more preferably 0.4 mm to 2 mm. If the thickness is less than 0.3 mm, it may be difficult to use due to curling during use, and if it exceeds 5 mm, it may be too thick and difficult to use. On the other hand, when the thickness is within the more preferable range, it is advantageous in that it is easy to handle and has a better usability.
In addition, the said thickness is a peacock type thickness measuring instrument, for example, using a pressing disk with a diameter of 44 mm, a sample of 150 mm × 100 mm, and leaving one point of each nonwoven fabric for 10 seconds with a dial gauge with a pressure of 2 kPa. Can be measured.
前記不織布の開孔部は、高圧ジェット水流の噴射装置及び波状に編まれたメッシュ開孔部材によって作製する。メッシュの波の凸部分水流が当たることで不織布が開孔する。この前記開孔部材は、噴射装置の噴射口と対向する位置に配置されており、スパンレース不織布の搬送方向に周回している。前記開孔部材は、例えば透水性の無端ベルトに、目開き(開孔部)が作製したい開孔率であるステンレス製やプラスチック製メッシュの網が設けられたものから構成されており、メッシュ開孔部材の波の高さを変えることにより不織布の開孔率を適宜調整することができる。なお、メッシュの網の織り方については、特に制限はなく、目的に応じて適宜選択することができる。 There is no restriction | limiting in particular as a manufacturing method of the said nonwoven fabric, A well-known manufacturing method can be used, For example, the method by a spun bond, a melt blow, a thermal bond, a chemical bond, a spunlace, a needle punch etc. is mentioned. Among these methods, the card web in which the hydrophilic fiber and the hydrophobic fiber constituting the nonwoven fabric are mixed is subjected to hydroentanglement treatment on the aperture member, and the constituent fibers are made of hydrophobic fibers that are heat-meltable fibers. It is preferable from the point of the touch that it is a nonwoven fabric which has the opening part manufactured by the spunlace method which heat-bonds.
The opening part of the nonwoven fabric is produced by a high pressure jet water jetting device and a mesh opening member knitted in a wave shape. The nonwoven fabric opens when the convex water flow of the mesh wave hits it. The opening member is disposed at a position facing the injection port of the injection device, and circulates in the conveyance direction of the spunlace nonwoven fabric. The aperture member is composed of, for example, a water-permeable endless belt provided with a mesh made of stainless steel or plastic mesh that has an aperture ratio (aperture portion) to be produced. By changing the height of the wave of the hole member, the hole area ratio of the nonwoven fabric can be appropriately adjusted. In addition, there is no restriction | limiting in particular about the weaving method of a mesh net | network, According to the objective, it can select suitably.
ここで、図1に示すように、シート状化粧料を構成する不織布10には、多数の開孔部1が規則的に形成されている。該開孔部1の形状は、特に制限はなく、目的に応じて適宜選択することができ、例えば、円形、楕円形、正方形、長方形、菱形、などが挙げられる。
前記不織布の開孔率とは、(開孔部1個の面積×開孔部の個数)/単位面積×100(%)で求めることができる。即ち、例えば、図2に示すような楕円形状の開孔部1の1個の面積は3.14×0.45mm×0.4mm=0.57mm2となり、該開孔部が単位面積(100mm2)当たり40個あるとすると、不織布の開孔率は、〔(0.57mm2×40個)/100mm2〕×100=23%となる。 The porosity of the nonwoven fabric is preferably 10% to 40%, and more preferably 15% to 23% from the viewpoint of antiseptic performance (particularly against Cepacia bacteria) and wiping feeling. When the opening ratio is less than 10%, the antiseptic performance (especially against cepacia bacteria) and the wiping feeling may deteriorate, and when it exceeds 40%, the antiseptic performance (especially against cepacia bacteria), the wiping feeling and the touch. May get worse.
Here, as shown in FIG. 1, a large number of
The open area ratio of the non-woven fabric can be determined by (area of one open part × number of open parts) / unit area × 100 (%). That is, for example, the area of one
