Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hair remover for removing waste hair such as shins and armpits with a hair-removing drug.

[0002]

2. Description of the Related Art As a method for removing wasteful hair, a shaving method using a razor or an electric razor, a wax-like hair removing agent for mechanically removing hair to remove hair, and a hair removing chemical for chemically removing hair are used. And the ones that are processed selectively.

In the above cases, the method using a razor has a high hair removing effect, and can effectively remove hair even if the hair is long, but it requires water and soap, and lacks in simplicity.
There is a risk of cutting the skin, and in the case of an electric razor, it is excellent in simplicity, but on the other hand, the hair removal effect is poor, and it becomes extremely difficult to use, especially when the hair grows.

In the above case, that is, as a depilator for mechanically pulling out waste hair, a mixture of wax, pitch and resin is warmed at the time of use and directly applied to the epilation part or applied to a cloth or the like. The object is to apply it to the hair-removing part, sufficiently solidify it, and then peel it off to pull out the waste hair from the hair root, but this is often accompanied by great pain, and the usability is extremely poor.

Further, in this method, the stratum corneum of the skin is damaged at the time of exfoliation, from which bacteria invade and purify,
It induces various skin disorders such as rashes and rough skin.

On the other hand, the above-mentioned method, that is, the method for chemically treating waste hair with a depilatory drug is classified into an inorganic drug and an organic drug according to the kind of drug used.

Alkali metal and alkaline earth metal sulfides are used as the inorganic drugs, and sodium sulfide, calcium sulfide, barium sulfide and the like are commonly used among them.

The depilatory is prepared by blending these drugs in a paste or cream base and further adding an alkali to adjust the pH to 10.0 to 12.5.

As for the depilatory action, the SH compound produced by hydrolyzing the sulfide reduces the cystine bond in the waste hair in the presence of alkali to remove the hair.

Further, the above-mentioned organic drug is mainly an alkaline earth metal salt of thioglycolic acid, and generally includes a calcium salt of thioglycolic acid.

The action of these depilatory agents is that the SH group of thioglycolic acid reduces the cystine bond in the presence of alkali to remove hair.

This method, that is, the method of chemically treating waste hair with a depilatory drug, is a drug compounded in a paste-like or cream-like base, and therefore may damage the skin. It is relatively easy to use, but it involves the work of applying it, and it is necessary to stain the clothes and the surroundings of the skin while applying it, and it is necessary to wipe it off with water or wash it with water after use, which makes it difficult to handle. There is a drawback of.

Therefore, recently, a hair remover containing an aqueous solution or emulsion of a polymer compound having a film-forming ability and a hair removing drug is applied to the hair removing site, and then a sheet-like material is attached and heat-treated to form a film. It has been proposed that the film is formed and the film is peeled off together with the sheet-like material (Japanese Patent Laid-Open No. 62-192316).

That is, this is one in which a depilatory is applied to the hair removal site, and then a sheet-like material is pasted to perform a heat treatment. In this heat treatment, the water content in the hair removing coating is 25% by weight. For a time and temperature sufficient to:

The heating temperature is usually 80 to 300 ° C., preferably 100 to 200 ° C., and the heating time may vary depending on the heating temperature, but as a guide, it is about 1 to 1.
It takes 10 minutes, and a household dryer or the like is used as the heat source.

[0016]

In this method, since the depilatory is applied to the depilatory site and the sheet-like material is adhered thereto, the clothes are not soiled, but the work of applying is involved. Also, heating is performed from the outside of the sheet-like material at a temperature of 80 to 300 ° C. However, since the sheet-like material covers the depilatory with this, the drying efficiency is poor, and as a result, it takes a relatively long time to dry. Therefore, during this drying, there are problems such that the drug is oxidized to generate sulfur, and a strong sulfur odor causes a discomfort to the user.

According to this method, a depilatory agent is applied to the depilatory site, and then the sheet-like material is stuck to the depilatory site.
It is heated and dried from the outside of the sheet material at 00 ° C, but this requires a heat source such as a household dryer, and since it is necessary to apply the heat source to the hair removal site to heat it, it is extremely troublesome. However, there is a problem that the place where it can be used is specified because the power source is required.

The present inventor has found that the creams and sheet materials used in the conventional depilatory and depilatory methods have a water content of 45.
It is as high as 10% by weight or more. Therefore, even if it is laminated on a support, the shape-retaining property of the depilatory substrate is poor, and the desired tack cannot be obtained, which makes it difficult to produce a medicated patch. Even if it is manufactured, if this is applied to the application site, the hair removal base material will flow out or overflow, so the hair removal base material and dehaired hair will remain at the application site during peeling and must be wiped off. Therefore, it was found that the handling property was extremely poor.

Therefore, the present inventor has conducted further studies, and in order to impart shape-retaining property to the hair-removing base material and obtain a desired tack, an emulsion of an adhesive polymer substance is used. In addition, when using this emulsion of the sticky polymer substance, it is possible to control the water content, use an emulsion of the sticky polymer substance with high tack, or increase the viscosity of the sticky polymer substance emulsion. It was found that it is desirable to add a tackifier, a focus agent, and a tackifier.

The present invention has been completed on the basis of the above findings, and comprises an emulsion of a depilatory drug and an adhesive polymer substance as an essential component, and has a water content specified within a required range for hair removal. By laminating the base material on the support, there is no need for coating work, there is no stain on the clothes, and there is no need to heat the application site after application, so it is extremely easy to use, and a hair-removing drug can be used. There is no stable and unpleasant sulfur odor, and when applied to the application site, the depilatory base material has good shape retention and the desired tack can be obtained, so there is no outflow or protrusion of the depilatory base material, and at the time of peeling. It is an object of the present invention to provide a depilatory and a depilation method using the depilatory, which does not leave the depilatory base material or depilated hair at the application site.

[0021]

[Means for Solving the Problems] In order to achieve the above-mentioned object, the present invention comprises a hair-removing drug (A) and an emulsion (B) of an adhesive polymer substance as essential components, and has a water content of It is characterized in that a depilatory substrate, which is 5 to 35% by weight of the total of (A) + (B), is laminated on a support.

The present invention will be described in detail below. The hair-removing drug used in the present invention is not particularly limited as long as it is a drug used as a depilatory, but especially in the molecule, S
Those having an H group or hydrolyzed to produce an SH compound, reduce the cystine bond in waste hair, and remove hair are desirable.

The hair-removing drug is at least one selected from thioglycolic acid, thioglycolic acid alkaline earth metal salts, thioglycolic acid alkali metal salts and thioglycolic acid alkaline earth metal hydroxides. Seed.

Specifically, for example, alkaline earth metal salts of thioglycolic acid such as calcium thioglycolate, magnesium thioglycolate, strontium thioglycolate, barium thioglycolate, beryllium thioglycolate, lithium thioglycolate, and thio. Examples thereof include alkali metal salts of thioglycolic acid such as sodium glycolate, potassium thioglycolate, and cesium thioglycolate.

In the present invention, thioglycerin may be used alone as an organic drug or as a mixture with other hair-removing drugs.

Further, in the present invention, the hair-removing drug is preferably homocysteine or its ester, or a salt thereof. This homocysteine or its ester or salts thereof exhibit an excellent hair removal effect.

Homocysteine or its ester salt means that since homocysteine or its ester has an amino group, it can form a salt with an inorganic acid or an organic acid, and homocysteine has a carboxyl group. Since it has, it can act on a base to form various salts.

Examples of the alkali metal sulfides or alkaline earth metal sulfides used in the present invention include the following. That is, examples of alkali metal sulfides include lithium sulfide, sodium sulfide, and potassium sulfide, and examples of alkaline earth metal sulfides include magnesium sulfide, calcium sulfide, strontium sulfide, or barium sulfide. Can be mentioned.

In the present invention, sulfides other than alkali metal sulfides and alkaline earth metal sulfides, such as zinc sulfide and aluminum sulfide, may be used.

In the present invention, the above-mentioned hair-removing drug may be used alone or in combination of two or more, but the content of the hair-removing drug is 0.5 to 25% by weight of the whole depilatory substrate. It is preferably prepared so that

When the content of the hair-removing drug is less than 0.5% by weight of the entire base material for hair removal, the hair-removing effect is poor and the commercial value is lowered. On the other hand, when it exceeds 25% by weight, the effect is limited. Occurs, which is meaningless, and is not preferable because the price increases and the adhesive property deteriorates. Therefore, from these viewpoints, it is desirable that the content of the depilatory drug is 1 to 15% by weight of the entire depilatory substrate.

The adhesive polymer emulsion used in the present invention is not particularly limited as long as the preparation can be adhered to and retained on the hair removal site. For example, vinyl acetate emulsion and acrylic. System emulsion,
Examples thereof include vinyl acetate-acrylic acid ester copolymer emulsion, styrene-acrylic acid ester copolymer emulsion, polyisoprene type emulsion, neoprene type emulsion or nitrile rubber type emulsion. These may be used alone or in combination of two or more. It can be mixed and used.

Of these, acrylic emulsions are preferred from the viewpoints of adhesive properties, cost, adhesion to the application site, etc., and particularly, the number of carbon atoms of the alkyl group is 1 to 30, especially tackiness, shape retention and adhesive properties. Furthermore, from the viewpoint of adhesion to the application site, an emulsion of (meth) acrylic acid alkyl ester of 6 to 14 or an emulsion of a copolymer of (meth) acrylic acid alkyl ester and another copolymerizable monomer is used. Can be mentioned.

This copolymerizable monomer can change the tack of the copolymer depending on the number of parts added, so that the adhesion to the skin and the shape retention can be improved, and the hydrophilicity can be increased.

The monomer of this kind is not particularly limited, but for example, (meth) acrylic acid, maleic acid, hydroxypropyl acrylate, (meth) acrylamide, dimethylacrylamide, t-butylacrylamide, acrylonitrile, vinyl acetate, vinyl propionate. , Vinylpyrrolidone, styrene, vinylimidazole and the like.

Among these adhesive polymer substances, at least one selected from the group consisting of vinyl acetate-acrylic acid ester copolymer emulsion, styrene-acrylic acid ester copolymer emulsion, and polyisoprene emulsion is used. The long-term stability of the obtained hair removal base material is secured, excellent tack and shape retention are obtained, the base material does not transfer to the skin, and the adhesive property and the adhesion to the application site are excellent. Most desirable from the standpoint of superiority.

In the above vinyl acetate-acrylic acid ester copolymer emulsion, the molar ratio of vinyl acetate to acrylic acid ester is 10 to vinyl acetate, and acrylic acid ester is 3 to 30, particularly acrylic acid ester 5 is used.
An emulsion of ~ 20 ensures long-term stability of the depilatory base material, provides excellent tack and shape retention, does not transfer the base material to the skin, and has adhesive properties and adhesion to the application site. It is most desirable from the viewpoint of excellent properties.

In this case, as the acrylic ester,
The alkyl group has 1 to 30 carbon atoms, and particularly 6 from the viewpoint of tackiness, shape retention and adhesive properties, and adhesion to the application site.
Alkyl esters of (meth) acrylic acid of -14 are preferred.

In the styrene-acrylic acid ester copolymer emulsion, the molar ratio of styrene to acrylic acid ester is 0.5 to 150 acrylic acid ester, particularly 1 acrylic acid ester to 10 styrene. An emulsion of ~ 100 ensures long-term stability of the depilatory base material, provides excellent tack and shape retention, does not transfer the base material to the skin, and has adhesive properties and close contact with the application site. It is most desirable from the viewpoint of excellent properties.

In this case, as the acrylic ester,
The alkyl group has 1 to 30 carbon atoms, and particularly 6 from the viewpoint of tackiness, shape retention and adhesive properties, and adhesion to the application site.
Alkyl esters of (meth) acrylic acid of -14 are preferred.

In the present invention, the hair-removing drug (A) and the emulsion (B) of the sticky polymer substance are essential components, and the water content is (A) + (B).
5 to 35% by weight based on the total weight of the hair removal base material is laminated on a support.

The content of water in the base material for hair removal, which contains the emulsion (B) of the hair-removing drug (A) and the adhesive polymer substance as an essential component, is 5 to 5% of the total of (A) + (B). 35% by weight
The reason why is required is as follows.

That is, if the content of water in the entire hair removing base material is less than 5% by weight, the water content is too small to obtain the required hair removal effect, while if it exceeds 35% by weight, the required hair removal effect is not obtained. It is not preferable because no heat-retaining or tacking is obtained, the base material for depilation flows out, and no adhesive residue is left on the application site when it is peeled off after being attached to the application site.

Therefore, from these viewpoints, it is desirable that the water content is 10 to 30% by weight based on the whole hair removing base material.

In the present invention, when the hair-removing drug (A) is added to the emulsion (B) of the adhesive polymer substance, the water content after the above-mentioned (A) is added to the above-mentioned (B) is It is sufficient that the amount is adjusted to 5 to 35% by weight, (A) is added to this (B), and they are sufficiently mixed.

By the way, when the water content in the above (B) is low and the viscosity is high, and therefore, after the above (A) is added to this (B), the water content in the (B) is, for example, 80% by weight or more, thereby lowering the viscosity of (B) and improving the mixing properties with (A), and then evaporating water to bring the water content in the depilatory base material into the above range. You can make adjustments like this.

In this case, the evaporation of water prevents the decomposition and alteration of (A) by drying under reduced pressure and forms an azeotropic mixture by adding alcohol, acetone or ether, thereby enabling low temperature drying. Therefore, it is necessary to prevent the decomposition and alteration of (A).

By the way, according to the experimental results of the present inventor,
It was confirmed that the above (A) is easily oxidized, and the metal salt of thioglycolic acid is relatively stable against water, but is oxidized and decomposed by oxygen to generate sulfur. Therefore, it is necessary to take care to minimize the effect of oxygen in the air when water is evaporated.

In the present invention, the above hair removal base material (A +
B), rosin, terpene resin, paraalkylphenol resin, terpene-phenol resin, coumarone-indene resin, xylene resin or petroleum resin tackifier, thickener such as aerosil or hydroxyethyl cellulose, kaolin, calcium carbonate, talc Or a bulking agent such as barium sulfate, an antioxidant such as fernaftyramine or 2,6-di-tert-butyl-4-methylphenol, a surfactant such as an anionic surfactant, a nonionic surfactant or a cationic surfactant, and Additives (C) such as pH adjusters such as hydroxides and carbonates of alkali metals and alkaline earth metals and bicarbonates may be added.

In this case, the mixing ratio of the depilatory base material (A + B) and the additive (C) is 1 to 30 parts by weight, particularly 5 to 25 parts by weight of (C +) based on 100 parts by weight of (A + B). It is desirable that the content is in the range of parts by weight, and the mixing ratio of (C) is
If it is less than 1 part by weight, the effect is poor and meaningless. On the other hand, if it exceeds 30 parts by weight, the adhesive property may be deteriorated, which is not preferable.

The pH of the depilatory substrate is the above p.
Depending on the H regulator, 9.5 to 13.5, especially 10.0 to
Adjusted to 12.5.

The support used in the present invention is not particularly limited as long as it has a sheet shape or a film shape and has flexibility. Specific examples include synthetic resin films and sheets, synthetic resin foam films and sheets, paper, non-woven fabrics, woven fabrics, metal foils, and composites thereof.

The thickness of this support is not particularly limited as long as it has a strength not to be damaged during handling, but from the viewpoints of handleability, cost and usability, it is 5 to 500 μm, Particularly, it is desirable that the thickness is in the range of 15 to 100 μm.

If desired, the support may be subjected to a treatment such as corona treatment, sizing, sanding or embossing in order to prevent the depilatory substrate from coming into close contact with the support and not coming off. It's good.

If desired, the support may be subjected to a primer treatment such as a coupling treatment in order to prevent the depilatory substrate from coming into close contact with the support so as not to come off.

The substrate for depilation is coated on this support. The thickness of the substrate is not particularly limited as long as it is held by the support and can be used, but generally 20 ˜2000 μm, particularly preferably 100 to 1500 μm.

If the thickness of the depilatory base material is less than 20 μm, the desired adhesive properties may not be obtained or the depilatory hair may be removed, depending on the type of the emulsion of the sticky polymer substance and the depilatory drug used. May be less effective, while 20
When the thickness exceeds 00 μm, the thickness becomes too thick and the rigidity is increased, the adhesion to the application site is deteriorated, the usability is deteriorated, and the cost is increased, which is not desirable.

In order to achieve the above object, the hair removing method of the present invention is characterized by applying the above-mentioned depilatory to the application site and then peeling it off.

That is, this hair remover is applied to the hair removal site of a human body or an animal and peeled off after a lapse of about 1 to 60 minutes, especially about 3 to 15 minutes, so that no waste of hair is caused and no hair loss occurs. Hair can be removed.

In this case, the depilatory base material of this depilatory has appropriate shape-retaining properties and adhesive strength, and since there is no adhesive residue or adhesive flow, the depilatory drug was hydrolyzed and produced. An SH compound is used for hair removal by reducing the cystine bond in waste hair in the presence of alkali and removing hair, or by removing the cystine bond in the presence of alkali by the SH group of thioglycolic acid. It is possible to remove hair that has been neatly removed by attaching it to the base material.

[0061]

The depilatory agent of the present invention comprises, as an essential component, an emulsion of a depilatory drug and an adhesive polymeric substance, and a depilatory substrate having a water content specified within the required range is laminated on a support. Moreover, since it is only necessary to attach the depilatory to the application site, there is no need for application work, and there is the effect of eliminating the stain on the clothes.

Since the depilatory agent of the present invention need only be applied to the application site and there is no need to heat it after application to the application site, it can be used extremely easily and the depilatory drug is stable. It has no unpleasant sulfur odor and can be used comfortably.

Furthermore, when the depilatory agent of the present invention is applied to the application site, the depilatory substrate has good shape retention and a desired tack can be obtained, so that the depilatory substrate does not flow out or stick out and is peeled off. At the same time, the depilatory base material and the dehaired hair do not remain on the application site, and at the same time, they have the action of not causing pain during peeling.

According to the hair removing method of the present invention, the hair removing base material has an appropriate shape-retaining property and adhesive force, and since there is no adhesive residue or adhesive flow, the hair removing drug is hydrolyzed. SH occurred
The compound reduces hair cystine bonds in waste hair in the presence of alkali, resulting in hair loss or SH of thioglycolic acid.
In the presence of an alkali, the hair, which has been hair-removed by reducing the cystine bond, adheres to the hair-removing base material, and has the action of removing cleanly hair-removed hair.
