A fixing step of fixing the adhesive tape on the top. Hereinafter, each step will be described.

(Film forming process)
The film forming step is a step of forming a solid film on the skin by applying a base agent containing a silicone acrylic resin and an alkane solvent to the skin.

The silicone-acrylic resin may be, for example, a homopolymer of siloxysilane having a (meth)acryloyloxy group, or a copolymer of the siloxysilane and another polymerizable monomer.

Examples of the siloxysilane having a (meth)acryloyloxy group include 3-(meth)acryloyloxypropyltris(trimethylsiloxy)silane, 3-(meth)acryloyloxypropylpentamethyldisiloxane, and 3-(meth)acryloyloxy. Examples thereof include propylbis(trimethylsiloxy)methylsilane and 3-(meth)acryloyloxypropylmethylbis(trimethylsiloxy)silane. These may be used alone or in combination of two or more.

These may be used alone or in combination of two or more.

The homopolymers and copolymers may be linear or branched, or may be slightly crosslinked, and may be homopolymers, copolymers, terpolymers or multipolymers. Good. The copolymer may consist of random copolymers or segments in nature.

The weight average molecular weight of the silicone acrylic resin is not particularly limited, but is usually 50,000 to several millions, for example, 50,000 to 500,000. The weight average molecular weight of the silicone acrylic resin can be appropriately adjusted by changing the initiator, the initiator concentration, the reaction temperature, the reaction solvent, the reaction method and the like.

The content of the silicone acrylic resin is, for example, preferably 0.5% by mass or more, more preferably 1.0% by mass or more, and 3.0% by mass or more based on the total amount of the base agent. Is more preferable. When the content of the silicone acrylic resin is 0.5% by mass or more based on the total amount of the base agent, the adhesive tape is less likely to slip and the skin is less affected when the adhesive tape is peeled off, so that the skin is more effectively Can be protected. On the other hand, the content of the silicone acrylic resin is, for example, preferably 50% by mass or less, more preferably 30% by mass or less, and further preferably 20% by mass or less, based on the total amount of the base material. When the content of the silicone acrylic resin is 50% by mass or less based on the total amount of the base agent, it is less likely to cause spots when the base agent is applied, and the skin can be easily adapted to the skin.

The alkane solvent is not particularly limited as long as it is an alkane-based solvent, and may include, for example, a straight-chain, branched-chain or cyclic alkane mainly.

Examples of such an alkane solvent include linear, branched or cyclic alkanes having 5 to 12 carbon atoms, among which isooctane such as 2,2,4-trimethylpentane and 3,4-dimethylhexane, Methylcyclopentane, n-heptane, n-octane, n-nonane and the like are preferably used. In particular, in consideration of quick-drying property, applicability, safety, etc., it is possible to efficiently form a solid film on the skin when the base agent is applied to the skin. , 2,4-trimethylpentane, n-heptane and the like are more preferable. These may be used alone or in combination of two or more.

The content of the alkane solvent is not particularly limited, and may be, for example, 50 mass% or more, 70 mass% or more, 80 mass% or more, and 90 mass% based on the total amount of the base agent. It may be the above. The upper limit of the content of the alkane solvent is not particularly limited, and may be, for example, 99% by mass or less and 95% by mass or less based on the total amount of the base agent.

The base material may contain other components, if necessary, in addition to the above-mentioned silicone acrylic resin and alkane solvent. Examples of such components include plasticizers, propellants, suspension aids, preservatives, antioxidants, active ingredients, drugs, antibacterial agents, insecticides, antimicrobial agents, antiviral agents, antitumor agents, Blood pressure and heart regulators, moisturizers, emollients, slip agents, waxes, flavors, fragrances, plant growth regulators, DEETs, plant insecticides, UV and IR absorbers, colorants, dyes, pigments, colored particles , Luster pigments, opalescent substances, surface optical brighteners, fungicides, solid materials, titanium dioxide, silica, tack reducers, sunscreens, texture modifiers, composition drying speed modifiers, mineral oils Aloe vera, Aloe vera oil extract, vitamin E, vitamin A, palmitate, triclosan, methyl salicylate, menthol, capsicum oleoresin, gyobai oil, squalane, peppermint, citronella, spearmint, jojoba oil, almond oil, oil, oil-soluble Examples include substances, vitamin C esters, vitamin C, aloe vera, witch hazel, quaternium 15, and the like.

The base agent may contain a plasticizer in order to soften the formed film and make it easy to adapt to the skin. Examples of the plasticizer include polyphenylmethyl siloxane copolymer, triethyl citrate, acetyl triethyl citrate, tri n-butyl citrate, acetyl tri n-butyl citrate, acetyl 2-ethylhexyl citrate, trimethylsiloxy silicic acid, and silicone. Oil, mineral oil, vegetable oil and the like can be mentioned. These may be used alone or in combination of two or more.

The content of the plasticizer is not particularly limited, and may be, for example, 1% by mass or more, 3% by mass or more, or 5% by mass or more, based on the amount of the silicone acrylic resin. The upper limit of the content of the plasticizer is not particularly limited, and may be, for example, 50% by mass or less, 30% by mass or less, or 20% by mass or less based on the amount of the silicone acrylic resin. ..

The base material may contain a propellant for aerosolization and spray application on the skin. Examples of the propellant include liquefied petroleum gas (LP gas), dimethyl ether, fluorohydrocarbon, carbon dioxide, nitrogen, nitrous oxide and the like. These may be used alone or in combination of two or more.

The content of the propellant is not particularly limited, but the volume ratio (stock solution/propellant) to the components of the base agent other than the propellant (hereinafter sometimes referred to as "stock solution") is preferably 10/90 to 90/. It is 10, more preferably 20/80 to 80/20, and further preferably 30/70 to 70/30. When the volume ratio is 10 or more, the stock solution can be freely spray-applied to various parts of the body. On the other hand, when the volume ratio is 90 or less, scattering in the air can be suppressed, and efficient coating can be performed. In addition, it is possible to suppress the generation of fine particles during use and reduce the inhalation risk.

In the film forming step, the above-mentioned base agent is applied to the skin to form a solid film on the skin. The applied base material is deposited on the skin to form a film, which becomes a solid film. For example, when the undercoating agent is applied to the release film, the obtained solid film can be peeled off from the release film. The method of applying the undercoat to the skin is not particularly limited, and a liquid undercoat may be applied as it is, or the above-described undercoat containing a propellant may be aerosolized and spray-applied to the skin. In particular, when forming a solid film over a wide area on the skin or when repeatedly using it, a solid film can be uniformly formed by a simpler method. Therefore, the base agent is aerosolized and spray-applied to the skin. The method is preferred.

(Fixing process)
In the fixing process, for the purpose of limiting, reinforcing and protecting the movable range such as joints, muscles, ligaments and tendons, and also for fixing members, etc., it is adhered to the skin through the solid film formed in the film forming process. This is the step of fixing the tape. That is, in the fixing step, the solid film is brought into contact with the adhesive surface of the adhesive tape to fix the adhesive tape on the skin via the solid film.

The adhesive tape is not particularly limited as long as it can be attached to the skin, but it is particularly preferable to use taping tape such as sports tape. By using the taping tape, it is possible to effectively suppress the positional deviation of the tape during exercise, and it is easy to exhibit the intended effect of taping.

According to the method of fixing the adhesive tape described above, it is possible to prevent the skin trouble due to the sticking and peeling of the adhesive tape while maintaining the fixing force of the adhesive tape to the skin. In other words, the invention according to the present embodiment can also be referred to as a method for protecting the skin to which the adhesive tape is attached, which is a method in which a base agent containing a silicone acrylic resin and an alkane solvent is applied to at least part of the skin. It can be said that the method includes a coating forming step of applying the coating to form a solid coating on the skin.

Further, the base agent used in the solid film forming step described above is useful as a base agent for forming a solid film for forming a solid film on the skin.

Hereinafter, the present invention will be described more specifically by way of examples, but the present invention is not limited to the examples.

<Preparation of base material>
The components shown in Table 1 were blended at the blending ratio (% by mass) described in Table 1 to prepare stock solutions AF. In Table 1, the following were used as the silicone acrylic resin, the plasticizer and the alkane solvent.
Silicone acrylic resin:
Isooctyl acrylate-3-methacryloyloxypropyl tris(trimethylsiloxy)silane-methyl methacrylate copolymer (manufactured by 3M)
Plasticizer:
Polyphenylmethylsiloxane copolymer (Toray Dow Corning Co., Ltd.)
Alkane solvent:
2,2,4-Trimethylpentane (Maruzen Petrochemical Co., Ltd.)

The stock solutions AF shown in Table 1 were filled in aluminum cans. After that, LPG (liquefied petroleum gas) as a propellant was filled at a ratio shown in Table 2 below, and then a valve and a button were attached to obtain a base agent having an internal pressure of 0.3 to 0.4 MPa. In Table 2, "stock solution/LPG" indicates the volume ratio of the stock solution and LPG.

Various evaluations were performed on the base material obtained above by the following methods.
<Skin fixability test>
(Shear test)
The base agent prepared in Examples 1 to 13 was sprayed onto a test plate with artificial leather from a distance of 10 cm to form a solid film on the artificial leather. After drying, 3M ^TM Multipore ^TM Sports Regular Elastic Fixing Tape (manufactured by 3M Japan Co., Ltd.) having a width of 25 mm and a length of 200 mm in which the end portion is folded in two so that the adhesive surface is exposed by 20 mm (hereinafter sports tape) is used as the solid film. It was placed on the artificial leather via the and the roller of 2 kg was reciprocated once to be fixed by adhesion. In addition, a case in which a sports tape is adhesively fixed by the same method on an artificial leather on which a base agent is not sprayed is Comparative Example 1, an underlap tape (Battlewin ^TM underlap tape, U70F( A non-adhesive urethane tape) made by Nichiban Co., Ltd. was wrapped around a test plate with artificial leather, and a sports tape was fixed in the same manner as Comparative Example 2, gel (Dreamwine gel (compounding ingredients: water, horse oil). , Isopentyl diol, denatured alcohol, glyceryl stearate, menthol, carbomer, allantoin, arnica flower extract, quince leaf/stem extract, horsetail extract, Hypericum flower/leaf/stem extract, sage leaf extract, yarrow extract, Altea root extract, chamomile flower extract, quince flower extract, aloe ferox leaf extract, purple root extract, squalane, sodium hydroxide, troferol, stearyl glycyrrhetinate, stearic acid PEG-10, stearic acid PEG-45, stearic acid Glyceryl (SE), BG, ethanol, methylparaben, fragrance), manufactured by Ikko Chemical Co., Ltd.) 0.02 g was applied on a test plate with artificial leather so that the area of the application site was 25 cm ^2, and sports were performed by the same method. The case where the tape was fixed was designated as Comparative Example 3.

Immediately after fixing the sports tape, the sports tape was pulled at a speed of 30 cm/min, the shear strength at this time was recorded, and an average value of three times was calculated. The results are shown in Table 3. The larger the value of the shear strength, the better the fixing force of the sports tape to the skin.

<Skin trouble test>
(Damage of keratin)
The base agent prepared in Examples 2, 7, 10 and 12 was sprayed onto the forearm from a distance of 10 cm to form a solid film on the skin. Subsequently, a sports tape having a width of 25 mm and a length of 75 mm was placed on the skin through the solid film, and a 2 kg roller was reciprocated once to be adhesively fixed. Further, Comparative Example 4 was a case where a sports tape was adhesively fixed by the same method on the skin on which the base agent was not sprayed. The number of testers for each sample was 12.

One hour later, the sports tape was peeled off at an angle of 180° and a speed of 15 cm/min, and the keratinous component (keratin) transferred to the adhesive surface of the sports tape was analyzed by an infrared transmittance analyzer (ATR method). Keratin, which is a keratinous component of the skin, shows strong absorption at 1539 cm ⁻¹ and 1630 cm ⁻¹ , and therefore the average value of the absorbance at the two wavelengths was relatively evaluated as an index of the amount of keratin exfoliation. The results are shown in Table 4. The keratin transcription amount in Table 4 is a value calculated from the average value of 12 testers. The smaller the value of keratin transcription, the more the damage of keratin on the skin is suppressed, and the skin trouble is suppressed.
