Description

  The present invention relates to a sheet-like cosmetic.

  In recent years, various wet sheet type products have been put into practical use for the purpose of wiping away sweat and stickiness to cleanse the skin and give a refreshing and comfortable skin feel. For example, there are products that are individually packaged one by one, and pocket tissue type products that are in units of 10 or more. These products are constituted by impregnating a sheet with a cosmetic liquid containing components such as cosmetic ingredients, cleaning agents, refreshing agents, bactericides, and fragrances. Recently, in order to give a more smooth feel, a sheet-like cosmetic compounded with powder has been proposed.

For example, Patent Document 1 describes a sheet-like cosmetic in which hydrophilic particles having sweat-absorbing properties are supported on a hydrophobic substrate, and Patent Document 2 includes a sheet in which a powder having a specific oil-absorbing property is blended. A cosmetic is described. However, there is a problem that the powder is easily detached from the skin surface and it is difficult to maintain the attached state. In particular, when sweating, it flows out together with the sweat, so that the amount of powder adhered to and maintained on the skin surface is significantly reduced. Moreover, even if the powder was given some sweat absorbency and sebum absorbability, it was saturated with sweat and easily detached from the skin with sweat, so that the smooth feeling could not be sustained.
Furthermore, Patent Document 3 describes that a sheet-like cosmetic using a combination of a specific two kinds of nonionic surfactants in a specific ratio together with powder and water can maintain a smooth feeling. .

JP 2007-119371 A JP 2004-345980 A JP 2013-116868 A

In recent years, the persistence of fragrance has been required due to increased preference for fragrance and increased deodorant awareness. In order to increase the sustainability of the scent, it is necessary to increase the amount of the fragrance added, and an additive such as an activator is required to improve the dispersibility of the fragrance.
When a fragrance or an activator for dispersing the fragrance is added to the sheet-like cosmetic described in Patent Document 3, the balance of essential components is lost, so that the effect of improving the feeling of smoothness is hardly exhibited. In addition, the feeling of use of the fragrance, the activator, etc. itself reduces the smoothness and the sustainability.
This invention makes it a subject to provide the sheet-like cosmetics which can maintain a smooth feeling and fragrance.

  The inventors have improved powder fixability on the skin by using a specific perfume and oil in combination with a specific ratio together with powder, water, and two specific nonionic surfactants. And it discovered that the volatilization of a fragrance | flavor was controlled and the sheet-like cosmetics which solved the said subject were obtained.

In the ratio of pulp, cotton and thermoplastic resin, the mass ratio of pulp and cotton is preferably 50% by mass or more, more preferably 80% by mass, and still more preferably 90% by mass.

Of these substrates, pulp and cotton are more preferable as the substrates because of ease of processing during production. Pulp and cotton are also preferable because they are excellent in the retention of the liquid composition, and transfer of powder, particularly hydrophilic powder, to the skin is also excellent. As for the pulp, it is preferable to use a thin pulp in order to achieve both softness and strength. Further, the pulp reinforced with the thermoplastic resin can give an appropriate thickness (bulkness) by embossing treatment, and the skin. It is preferable because it does not get wet too much. Furthermore, by sticking together a plurality of sheets by heat sealing, it is possible to provide a good usability with a soft and wiping thick sheet.

The thickness of the sheet is preferably 0.15 to 1.30 mm (measured with a dial gauge with a pressure of 20 gf / cm ² load) from the viewpoint that it has a wiping response and gives a good feeling during wiping.

Further, from the viewpoint of powder transfer from the sheet to the skin, the transmittance of the sheet-like base material is preferably 50% or less, more preferably 30% or less, further preferably 25% or less, and 21.5% or less. Is even more preferred. In the present invention, the transmittance of the sheet is measured under the following conditions, and the higher the transmittance is, the closer the fiber interval is. A sheet having such a permeability is considered to have an effect of enhancing the transferability of the powder to the skin by gathering powder on the sheet surface because the fiber interval is close and the gap is small. Further, from the viewpoint of usability, the transmittance of the sheet-like substrate is preferably 10% or more, more preferably 13% or more, more preferably 15% or more, and even more preferably 18% or more.
Here, a transmittance | permeability shows the total light transmittance obtained when a haze value of a JIS specification K7136 sheet base material is measured using a haze meter.
In order to obtain a sheet having the above-mentioned permeability, for example, a combination of powdered fibers is used to reduce voids. In the case of a pulp sheet, the beating time is increased during paper making, and the beating degree is increased. The method is mentioned.

  The sheet-like cosmetic composition of the present invention removes sweat and sebum dirt by wiping the skin and cleans it, and the powder effectively adsorbs and remains on the skin for a long time. In addition, it can give a smooth feel with little bulkiness. Cleans skin and keeps skin comfortable.

  The sheet-like cosmetic of the present invention, for example, when used on the face, not only effectively removes sebum and leaves the powder and moisturizer to keep the skin comfortable, but also makes it easy to remake. improves. In addition, when an antiperspirant and a bactericidal agent are blended, these active ingredients remain on the skin for a long time after cleansing the skin, so that a continuous antiperspirant / deodorant effect can be expected. Moreover, the usefulness of the product of the present invention is also high in a method of using it on the body's unwanted hair treatment site and preparing the skin after shaving. In other words, by applying to the skin before using the razor, the part is moistened and the powder remains, so that the razor can be made slippery without damaging the skin, and a comfortable skin feel can be achieved.

Production Example 1
A beaker was charged with 82 g of lauryl methacrylate, 3 g of methacrylic acid, 15 g of ethylene glycol dimethacrylate, and 2 g of lauroyl peroxide, and dissolved by stirring. To this, 400 g of ion-exchanged water in which 0.75 g of N-stearoyl-N-methyltaurine sodium (SMT) was dissolved was added and dispersed with a homomixer until the particle size became 2.2 μm. Further, 3.9 g of 1N NaOH was added dropwise for neutralization. The dispersion was poured into a four-necked flask and purged with nitrogen for 30 minutes while stirring. The temperature inside the flask was heated to 80 ° C. with an oil bath, polymerization was performed for 5 hours after reaching 80 ° C., and then cooled to room temperature. The dispersion of the polymerized particles was lyophilized and the particles were recovered to obtain a lauryl methacrylate / ethylene glycol methacrylate / sodium methacrylate copolymer. (Average particle size 2.2μm, sphericity 95% (90/5 min))
