DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an anti-shearing agent excellent in holding a breast in a brassiere and preventing the brassiere from shifting.

[0002]

2. Description of the Related Art Conventionally, as a women's chest underwear, a bra has been used to improve the shape of the breast and make the silhouette of the upper body beautiful,
It has been used for the purpose of preventing the shape of the breast from being deformed and preventing trouble during exercise due to shaking. Recently, in order to respond to the desire for a large, well-shaped breast, which has long been a longing for women since long ago, push the subcutaneous fat etc. in the vicinity and push it into the bra, push it toward the center of the chest, and push up as if the cup size was Underwear that looks as if it has increased is popular.

[0003] These underwear require a stronger holding force in order to forcibly hold the subcutaneous fat and the like which are originally near. For that, long line bras,
A method of increasing the frictional resistance with the skin by expanding the belt portion of the cup frame edge, and a method of more strongly holding the shape by using a shape memory wire, a double wire, or the like have been adopted. However, in these methods, the holding effect was not sufficient, and the underwear was strongly adhered to the skin due to a strong pinching force, biting, and severely abrased. Nevertheless, a shift preventing agent for avoiding these problems and a skin damage preventing agent for reddening and abrasion of the skin by a bra have not been developed and marketed.

[0004] Other fields include non-aqueous socks comprising a solidifying agent, a solvent, an adhesive component, and a gel modifier (JP-A-52-76148), 1 part of polyacrylic acid, glycerin and / or polyalkylene. Glycol 0.2
There has been reported an adhesive composition (Japanese Patent Publication No. 52-24055) for bonding socks, wigs and the like to human skin, comprising from 1 part to 1 part, alcohols and / or 8 to 20 parts of water.

[0005] However, the body part to which the anti-slip agent for brassiere according to the present invention is applied is a portion from the armpit to the lower part of the breast, which is exposed to the outside such as the scalp or the outer skin of the limbs. Unlike this, it is a part that is usually under clothing, has high surrounding temperature and humidity, and has sensitive skin. When the socks or the adhesive composition of the present invention is applied to such a site, the adhesive strength is too strong, the viscosity is too high, the stickiness is severe, redness, itching or discomfort is felt. It was not for practical use.

[0006] That is, an object of the present invention is to solve these problems and to provide an excellent effect of holding the breast in the brassiere and preventing the brassiere from being displaced without abrasion and other adverse effects on the skin, and to be easily used. It is an object of the present invention to provide a brassier slip preventing agent.

[0007]

The present inventors have conducted intensive studies on the above-mentioned problems, and as a result, surprisingly, polyvinyl pyrrolidone and / or vinyl pyrrolidone-vinyl acetate copolymer and other water-soluble polymers And by using a brassiere slip prevention agent consisting of an adhesive containing alcohol, it has appropriate adhesiveness, prevents direct contact between the skin and the bra, and finds that these problems can be solved. In addition, it has been found that it can be easily used by using a tube container having a substantially hemispherical tip coating portion provided with a discharge hole having a diameter of 0.5 to 7.0 mm at substantially the center,
The present invention has been completed.

That is, the object of the present invention is attained by an anti-shear agent for brassiere comprising an adhesive containing polyvinylpyrrolidone and / or a vinylpyrrolidone / vinyl acetate copolymer and another water-soluble polymer and alcohol. . Further, it is further achieved by using a tube container having a substantially hemispherical tip application portion provided with a discharge hole having a diameter of 0.5 to 7.0 mm substantially at the center.

[0009]

Embodiments of the present invention will be described below in detail.

The polyvinylpyrrolidone and the vinylpyrrolidone / vinyl acetate copolymer used in the present invention are known water-soluble substances, and are generally used in pharmaceuticals, cosmetics and the like. Polyvinylpyrrolidone has a molecular weight of 8,000 to 70
You can get and use something of about 0000,
In order to impart an appropriate viscosity to the adhesive, a molecular weight of 30,
000-700,000 are more preferred. The vinylpyrrolidone / vinyl acetate copolymer can be obtained and used in a composition molar ratio of (7: 3) to (3: 7). For the same reason, the same molar ratio of (6: 3) is used. 4) ~
(4: 6) is more preferable.

The amount of the polyvinylpyrrolidone, vinylpyrrolidone / vinyl acetate copolymer is preferably 1.0 to 20.0% by weight (hereinafter abbreviated as wt%) based on the total amount of the anti-shear agent for brassiere according to the present invention. And more preferably 2.
0 to 10.0 wt%. If it is less than 1.0 wt%, the effect of preventing displacement may not be sufficient, and 20.0 w
If it exceeds t%, stickiness may be so strong that it may not be practical.

Other water-soluble polymers in the present invention include:
Any substance that has a thickening property and does not adversely affect the skin can be used regardless of whether it is a natural product or a synthetic product, but polyvinyl alcohol, carboxyvinyl polymer, polyvinyl methyl ether, and sodium alginate are Particularly preferred from the viewpoint of safety and tackiness.

These water-soluble polymers are used in an amount of 0.01 to 30.0% based on the total amount of the anti-shear agent for brassiere according to the present invention.
0 wt% is preferable, and 0.1 to 20.0 wt% is particularly preferable.

The alcohol in the present invention is preferably a volatile lower alcohol, and particularly preferably ethanol, propanol and isopropyl alcohol from the viewpoint of safety.

5 to 40% of these alcohols, based on the total amount of the anti-shear agent for brassiere according to the present invention, causes an early increase in viscosity due to volatilization at the time of application, and prevents the anti-drip agent for brassiers from dripping and mounting the bra. It is preferable from the viewpoint of the ease of drying of the subsequent shift preventing agent.

The viscosity of the anti-shear agent for brassiere according to the present invention is 100 to 100 as measured by a B-type viscometer at 25 ° C.
500,000 cps, preferably 2,000 cps.
Those having 0 to 400,000 cps are particularly preferred. 10
If it is less than 0 cps, it may be undesirable because liquid dripping occurs at the time of application and the number of times for applying a sufficient amount is required. On the other hand, if it exceeds 500,000 cps, the viscosity becomes too strong, it is difficult to discharge from the container, and it becomes difficult to apply uniformly, which may be undesirable.

The anti-shear agent for brassieres according to the present invention includes surfactants, preservatives, fragrances, antioxidants, film-forming agents, alkalis as pH adjusters, plasticizers, chelating agents, ultraviolet absorbers, silicones. In addition, a derivative thereof, an oily substance, a gelling agent, a viscosity modifier, a coloring matter, a humectant, and the like can be appropriately compounded within a range that does not impair the object of the present invention. Further, in order to have a further anti-inflammatory action or anti-allergic action, corticosteroids, glycyrrhizic acid, glycyrrhetinic acid and the like can be appropriately compounded within a range not to impair the object of the present invention.

As the coating container used in the present invention, a tube container having a substantially hemispherical tip coating portion provided with a discharge hole having a diameter of 0.5 to 7.0 mm substantially at the center thereof can be prepared by squeezing the tube container. Anti-slip agent for brassiere
It is particularly preferable because it can be easily and uniformly applied to an appropriate range. If the discharge hole is less than 0.5 mm, the brassier slip preventive agent may be difficult to come out of the discharge hole. It is not preferable because it makes it difficult to apply it to the skin, or there is a fear that it may be applied to the skin beyond a necessary range. Note that the tip application portion does not necessarily need to be a true spherical shape, but may be a substantially hemispherical shape. Other than a semi-spherical shape, a thick layer of anti-slip agent for brassieres is formed around or at the center of the tip application part, and smooth application of the tip application part on the skin is impaired, making uniform application difficult. May be undesirable. As another coating container, a tube container having a coating portion made of a soft sponge having open cells such as urethane at the tip portion, or a roll-on tube container having a rotatable sphere at the tip coating portion is used for the brassiere according to the present invention. In the slip prevention agent,
It is not preferable because clogging or poor ball rotation occurs or uneven coating occurs.
