Description

Portable Powder Sheet Type Cosmetic composition

The present invention relates to a powder sheet-like cosmetic composition containing powder, particularly a sheet-type cosmetic composition which effectively attaches the powder to a sheet such as a nonwoven fabric and provides a fresh and comfortable feeling when used, and a method of manufacturing the same.

Background Art Conventionally, wet type sheet products for the purpose of cleaning a part of a body such as a face, a neck, a limb and the like have been put into practical use. These products can be drawn one by one, pocket-type tissue products in ten-piece units, or dozens of box-type products. These products are impregnated with a component such as a cosmetic removal component, a refreshing agent, a disinfectant, and a fragrance component, and are used for the purpose of simply cleaning and refreshing the skin after use.

However, the conventional products are effective for the purpose of cleansing the skin, but the oil or moisture on the skin was wiped off more than necessary to give a feeling of dryness or discomfort. For example, when used on fragile skin such as around the neck, the skin is rough or troublesome. It is said that these wet type products can be used for the whole body, but in fact, it can clean only a specific part such as a dirty part of the hand or a relatively frequently used part and is unsuitable for the above phenomenon when used for the whole body.

Therefore, the present inventors impregnated the powder with an aqueous medium together with a sheet to solve the above problems, that is, skin dryness, causing skin trouble, and solve the problems after use, while also providing a pleasant skin (Wet sheet containing powder) Sheet).

That is, the present invention is a sheet-like cosmetics to be supported on a sheet-like substrate with an aqueous medium using a synthetic polymer material and natural minerals.

The present invention also relates to a method of reducing the dynamic frictional resistance of a substrate by sliding the sheet-like cosmetic of the present invention to the skin and transferring the powder onto the skin.

In addition, the present invention provides a method for producing a laminated sheet-like cosmetics comprising impregnating a liquid composition containing a synthetic polymer material and a natural mineral in an aqueous medium on a sheet-like substrate, supporting the powder and the aqueous medium, and cutting and laminating it. It is about.

The sheet cosmetics of the present invention can be prepared by dispersing a synthetic polymer material and a natural mineral in an aqueous medium such as water or hydrous ethanol and supporting the substrate by a method such as coating.

Examples of the synthetic polymer in the powder used in the present invention include synthetic silica beads, hydrophobic silica powder, nylon resin, polystyrene resin, fine pearl, technology polymer SB, fine powder, polyethylene resin, flow beads, polymethyl methacrylate resin Moto Micropea M, Technology Polymer Fine Powder, Divinylbenzene Resin, Polyurethane Resin, Benzoguanine Resin, Melamine Resin, Lungol Resin, Fluorine Resin, Methylhydrogendimethyl Polysiloxane, Pelfluoroalkyl Phosphate Diester The surface-water-repellent powder, Si-Talc JA46R, PF-3LL-5 Talc etc. are mentioned with the compound containing silicon and fluorine, such as ethanol amine salt. Among them, organic silicone group-containing polymers such as silica beads and silicone resins are preferred in view of lowering the dynamic friction during skin retention, imparting slipperiness to the skin, and remaining on the skin.

Powders used as natural minerals include talc, mica, mica, kaolin, bentonite, silicic acid, silicic anhydride, magnesium silicate, magnesium oxide, zinc oxide, titanium oxide, aluminum oxide, aluminum lactate, alum, calcium sulfate, barium sulfate, Magnesium sulfate and the like are exemplified, but zinc trioxide is particularly preferable because of good skin adhesion.

It is preferable that the shape of such powder is mainly spherical. The friction coefficient of the powder decreases according to the spherical shape of the powder, and the slipperiness of the skin increases. In the present invention, the content of the spherical phase measured by the following is preferably 70% or more, particularly preferably 90% or more.

Take an electron micrograph of a solid particle on an electron microscope and randomly select 100 particles that are not polymerized between the particles, and the projection image of the particle represents a circle, or the circumscribed circle of the projection image, and represents 90% of the radius of the circumscribed circle. It is called the true spherical shape of the particle as the number of the shape having all the contours of the projection between the concentric circle and the circumferential circle having a radius.

As the particle size of the powder of the present invention, the presence of 90% by weight or more of the starch in the range of 2-15 microns is preferable in the above-mentioned to enhance the skin texture, and it is particularly preferable that the powder having a particle size of 4-6 microns is 90% by weight or more of the starch. Do.

On the other hand, the powder having a particle size of less than 0.5 micron is less effective for the skin texture or gives an unpleasant feeling of squeaking, and therefore, the lesser one is preferable, and the inhalation of the powder having a particle size of more than 30 microns is better.

Therefore, the amount of such powder is preferably 10% by weight or less based on the total amount.

In the sheet-like cosmetics of the present invention, the powder containing 0.5-30 microns in particle size impinges on one square meter of the substrate to contain 0.1-20 g, especially 0.5-10 g, in that it gives a touch to the skin and does not whiten the skin. desirable.

Moreover, the impregnation rate of the aqueous medium containing powder can be 50-500 weight% of the weight of a base material, Especially since 150-350% improves a usability, it is preferable. In the present invention, either a nonwoven fabric or a woven fabric of natural fibers or synthetic fibers can be used as the sheet-like substrate. Specific examples include rayonne, acetate, acryl, polyester, polyethylene, polypropylene, polyurethane, polyamide, cotton Nonwovens or woven fabrics of cotton and hybrids thereof, as well as pulp sheets reinforced with wet and dry pulp sheets, thermoplastics (polyethylene, polypropylene, polyethylene terephthalate, etc.) (pulp sheet, etc.) Such a sheet is preferable because the powder is collected on the surface of the sheet so as to be close to the fiber interval, but the pulp and cotton are described for easy processing during manufacturing. Particularly preferred is pulp, which is to be polymerized into thin pulp because it is necessary to balance both softness and strength. In addition, the pulp reinforced with thermoplastic resin may be given an appropriate thickness by embossing, and it may be desirable to soften the pulp by boiling. It is also possible to further enhance the feeling of use by partially overlapping the sheet) into a sheet of moderate thickness that is soft and easy to steal.

In addition, the sheet-like cosmetics of the present invention may contain a silicone oil in order to enhance the texture. Silicone oil has a property of high adsorption to the skin, but has an effect of increasing the adsorption of the powder on the skin. Silicone oils include methyl polysiloxane, dimethicon, diethyl polysiloxane, methyl phenyl polysiloxane, fatty acid modified polysiloxane, higher alcohol modified polysiloxane. ), And a modified polysiloxane of a network is particularly preferred because dimethicone is less sticky and has good compatibility with a water-soluble medium. In addition, when the viscosity is less than 1 mm ² / s, there may be a problem such as skin irritation may be undesirable. As for the compounding quantity of this silicone oil, 0.1-1 weight% is preferable with respect to the total amount.

The sheet-like cosmetics of the present invention can clean the skin to remove dirt and clean, and at the same time the powder is effectively adsorbed to the skin and remain, giving a fresh and smooth skin texture to the skin for a long time. In addition, by combining anti-inflammatory agents, whitening agents, UV care agents, fungicides, limiting agents, refreshing agents, fragrances, etc., these ingredients can be powdered, remain on the skin for a long time, and the skin can be functionally conditioned after use. You can also give a refreshing and fragrance.

For example, when used on the face, it effectively removes sebum and at the same time retains and comforts powders and moisturizers, and keeps these active ingredients on the skin for a long time in addition to keeping them clean when formulated with fungicides. . In addition, by applying to the skin before use of the razor, by moistening the corresponding area and at the same time to retain the powder, it is possible to improve the slipperiness of the razor and to achieve a comfortable texture without hurting the skin.

If the sheet-like cosmetics of the present invention are used to clean the skin of the body such as face, neck, limbs, etc., the user will feel a fresh and smooth texture because the powder remains sufficiently on the skin after application and the dynamic friction resistance is lowered. can do.
