Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a slip prevention agent which is excellent in holding a breast in a brassiere and preventing the brassiere from being displaced.

[0002]

2. Description of the Related Art Conventionally, a brassiere as a chest underwear for women has been used to adjust the shape of the breast and to make the silhouette of the upper body look beautiful.
It has been used for the purpose of preventing shape collapse of the breast and preventing obstacles during exercise due to shaking. Recently, in order to respond to the desire for large, well-shaped breasts that women have long admired, push subcutaneous fat in the vicinity into the brassiere, push it toward the center of the chest, and push it up as if the cup size. Underwear that looks as if it has increased is popular.

[0003] These underwear are required to have a stronger holding force in order to forcibly hold the subcutaneous fat or the like which is originally in the vicinity. For that, long line bras,
A method of increasing the frictional resistance with the skin by expanding the belt portion of the edge of the cup frame, and a method of using a shape memory wire, a double wire, or the like to more firmly clamp it are used. However, with these methods, the holding effect was not sufficient, the underwear was strongly marked on the skin due to the strong gripping force, and it could bite into the skin, resulting in severe abrasion. Nevertheless, no slippage preventing agent for avoiding these problems and a skin damage preventing agent against reddening or abrasion of the skin due to a brassiere have been developed and marketed.

Other fields include non-aqueous soot stoppers composed of 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
An adhesive composition (Japanese Patent Publication No. 52-24055) for socks, wigs, etc. and human skin, containing 1 to 1 part of alcohol and 8 to 20 parts of water has been reported.

However, the body part to which the anti-slip agent for brassiere according to the present invention is applied is a part around the breast from the axilla to the lower part of the breast, which is exposed to the outside like the scalp and the outer skin of the limbs. Unlike, it is a part that is usually under clothes, has high temperature and humidity around it, and has sensitive skin. When the socking stop or the adhesive composition of the present invention is applied to such a part, the adhesive force is too strong, the viscosity is too high, the stickiness is severe, reddening, itching or discomfort occurs. However, it was not for practical use.

In other words, the object of the present invention is to solve these problems, and is excellent in the effect of holding the breast in the brassiere and preventing the displacement of the brassiere, without the adverse effects on the skin such as abrasion and the like, and it is easy to use. It is to provide a shift preventive agent for a brassiere.

[0007]

Means for Solving the Problems As a result of intensive studies on the above problems, the present inventors have surprisingly found that polyvinylpyrrolidone and / or vinylpyrrolidone / vinyl acetate copolymer and other water-soluble polymers And, by using an anti-misalignment agent for a brassiere, which comprises an adhesive containing alcohol, it has appropriate adhesiveness, prevents direct contact between the skin and the brassiere, and found that these problems are solved. In addition, they have found that it can be easily used by using a tube container having a substantially hemispherical tip coating portion having a discharge hole having a diameter of 0.5 to 7.0 mm approximately at the center,
The present invention has been completed.

[0008] That is, the object of the present invention is achieved by an anti-slip agent for brassiere which comprises an adhesive containing polyvinylpyrrolidone and / or vinylpyrrolidone / vinyl acetate copolymer and other water-soluble polymer and alcohol. . Further, it is further achieved by using a tube container having a substantially hemispherical tip coating portion in which a discharge hole having a diameter of 0.5 to 7.0 mm is provided at the substantially center.

[0009]

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described in detail below.

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 8,000-70.
It is possible to obtain and use about 10,000 items,
In order to impart an appropriate viscosity to the adhesive, a molecular weight of 30,
Those of 000 to 700,000 are more preferable. As the vinylpyrrolidone / vinyl acetate copolymer, those having a composition molar ratio of (7: 3) to (3: 7) can be obtained and used, but for the same reason, at the same molar ratio (6: 4) ~
(4: 6) is more preferable.

The polyvinylpyrrolidone and the vinylpyrrolidone / vinyl acetate copolymer are preferably contained in an amount of 1.0 to 20.0% by weight (hereinafter abbreviated as wt%) based on the total amount of the shift preventive agent for brassiere according to the present invention. , And more preferably 2.
It is 0 to 10.0 wt%. If it is less than 1.0 wt%, the shift prevention effect may not be sufficient, so 20.0 w
If it exceeds t%, the product may be too sticky and not practical.

The other water-soluble polymer in the present invention is
All natural and synthetic substances can be used as long as they have a thickening property and do not adversely affect the skin, but polyvinyl alcohol, carboxyvinyl polymer, polyvinyl methyl ether, sodium alginate It is particularly preferable in terms of safety and adhesiveness.

These water-soluble polymers are contained in an amount of 0.01 to 30.0 with respect to the total amount of the shift preventive agent for brassiere according to the present invention.
0 wt% is preferable, and 0.1-20.0 wt% is particularly preferable.

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

5 to 40% of these alcohols bring about an early increase in viscosity due to volatilization at the time of application, with respect to the total amount of the shift preventive agent for brassiere according to the present invention. It is preferable from the viewpoint of easy drying of the anti-deviation agent afterwards.

The viscosity of the brassiere prevention agent according to the present invention is 100 to 100 when measured by a B-type viscometer at 25 ° C.
500,000 cps is preferable, 2,000
Particularly preferred is 0 to 400,000 cps. 10
If it is less than 0 cps, liquid dripping may occur during coating, and it may take several times to coat a sufficient amount, which is not preferable in some cases. 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 it uniformly, which is not preferable in some cases.

The anti-misalignment agent for brassiere according to the present invention includes a surfactant, an antiseptic, a fragrance, an antioxidant, a film-forming agent, an alkali as a pH adjusting agent, a plasticizer, a chelating agent, an ultraviolet absorber and a silicone. And derivatives thereof, oily substances, gelling agents, viscosity modifiers, dyes, humectants and the like can be appropriately added within a range not impairing the object of the present invention. Further, in order to have a further anti-inflammatory effect or anti-allergic effect, adrenocortical hormone, glycyrrhizic acid, glycyrrhetinic acid, etc. can be appropriately blended within a range not impairing 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 having a discharge hole having a diameter of 0.5 to 7.0 mm in the substantially center thereof is an appropriate amount by squeezing the tube container. Anti-slip agent for brassiere,
It is particularly preferable because it can be uniformly and easily applied to an appropriate range. If the discharge hole is less than 0.5 mm, the brass anti-slip agent may be difficult to come out of the discharge hole, and if it is more than 7.0 mm, a required amount of the brass anti-slip agent adheres to the tip coating portion, resulting in a uniform coating. Is difficult to apply, and there is a risk of applying it to the skin beyond the required range, which is not preferable. Note that the tip application portion does not necessarily have to be a true spherical shape, and may be a substantially hemispherical shape. Except for the approximately hemispherical shape, it is difficult to apply evenly because a thick layer of anti-misalignment agent for brassiere is formed on the peripheral part or the central part of the tip application part, and smooth sliding on the skin of the tip application part is impaired. May be unfavorable. As another coating container, a tube container having a coating portion made of a soft sponge having continuous cells such as urethane at the tip portion, or a roll-on tube container having a rotatable ball in the tip coating portion is used for a brassiere according to the present invention. In the anti-misalignment agent,
It is not preferable because clogging, poor ball rotation may occur or uneven application may occur.
