Non-water thickeners include hydrocarbon copolymers. Hereinafter, each configuration will be described.

<Exothermic component>
The exothermic component is a component that generates heat when it comes into contact with moisture, and is used for the purpose of imparting a warm feeling to the application site. Examples of the application location include skin and hair.

  The exothermic component is not particularly limited as long as it is a component that can generate heat upon contact with moisture. Examples of the exothermic component include metal halides such as magnesium chloride and calcium chloride, and zeolite that generates heat by adsorbing moisture.

  The content of the exothermic component is not particularly limited as long as it contains an amount for obtaining a desired exothermic effect. As an example, the exothermic component is preferably 5% by mass or more, and more preferably 10% by mass or more in the coating composition. Further, the exothermic component is preferably 40% by mass or less, more preferably 35% by mass or less, in the coating composition. When the content of the exothermic component is less than 5% by mass, the exothermic effect tends to be insufficient. On the other hand, when the content of the exothermic component exceeds 40% by mass, the exothermic effect tends to be excessive.

<Non-water thickener>
The non-water thickener is used for the purpose of uniformly dispersing the exothermic component in an oily solvent to be described later, suppressing separation of the resulting coating composition, and discharging without hardening even at low temperatures. The coating composition of the present embodiment only needs to contain a hydrocarbon copolymer as a non-water thickener, and in addition to the hydrocarbon copolymer, alkyl dimethicone, polysilicone, high grade as a non-water thickener. Fatty acid esters and the like may be included. In the present embodiment, “non-water” refers to a state in which the exothermic component dispersed in the oil-based solvent is stable and does not contain moisture or is reduced to a certain extent without generating heat.

  The hydrocarbon copolymer is not particularly limited, and for example, a copolymer obtained by appropriately polymerizing an aromatic hydrocarbon having a polymerizable double bond and an aliphatic hydrocarbon having a polymerizable double bond. Polymers can be used.

(Aromatic hydrocarbons having a polymerizable double bond)

If an example is given, as an aromatic hydrocarbon, a C6-C10 aromatic hydrocarbon is mentioned. The aromatic hydrocarbon of the present embodiment preferably has 7 to 9 carbon atoms from the viewpoint of easily adjusting the viscosity of the coating composition.

  More specifically, the aromatic hydrocarbon includes an aromatic vinyl monomer. By using an aromatic vinyl monomer as the aromatic hydrocarbon, the exothermic component is easily dispersed uniformly in the oily solvent, and separation is unlikely to occur even when the resulting coating composition is stored for a longer period of time.

  Examples of the aromatic vinyl monomer include styrene, vinyl toluene, α-methyl styrene, and methoxy styrene. When these are polymerized, 1 type may be used and multiple may be used. Among these, styrene is preferable as the aromatic vinyl monomer. By using these as aromatic vinyl monomers, the exothermic component is easily dispersed more uniformly in the oily solvent, and separation is less likely to occur even when the resulting coating composition is stored for a longer period of time. As a result, the obtained coating composition can give a particularly stable warm feeling to the application site when applied.

(Aliphatic hydrocarbon having a polymerizable double bond)
The aliphatic hydrocarbon having a polymerizable double bond constituting the copolymer is not particularly limited. As an example, the aliphatic hydrocarbon includes an aliphatic hydrocarbon having 2 to 10 carbon atoms. Such an aliphatic hydrocarbon may be linear or may have a branched chain. The aliphatic hydrocarbon of the present embodiment preferably has 2 to 6 carbon atoms from the viewpoint of easily preventing solidification at low temperatures.

  More specifically, aliphatic alkene is mentioned as an aliphatic hydrocarbon. By using an aliphatic alkene as the aliphatic hydrocarbon, the exothermic component is easily dispersed uniformly in the oily solvent, and separation is unlikely to occur even if the resulting coating composition is stored for a longer period of time.

  Examples of the aliphatic alkene include ethylene, propylene, butene, decene, isoprene, butylene, butadiene, and pentadiene. When these are polymerized, 1 type may be used and multiple may be used. Among these, ethylene, propylene, butene, isoprene, butylene, and butadiene are preferable as the aliphatic alkene. By using these as the aliphatic alkene, the exothermic component is easily dispersed more uniformly in the oily solvent, and even if the resulting coating composition is stored for a longer period of time, it is difficult to cause separation. As a result, the obtained coating composition can give a particularly stable warm feeling to the application site when applied.

  Returning to the description of the copolymer, the aromatic hydrocarbon having a polymerizable double bond and the aliphatic hydrocarbon having a polymerizable double bond may be combined appropriately to produce a copolymer. it can. For example, from the above aromatic hydrocarbon having a polymerizable double bond and aliphatic hydrocarbon having a polymerizable double bond, an aromatic hydrocarbon having a polymerizable double bond and a polymerizable double bond It is possible to produce a copolymer with an aliphatic hydrocarbon having a copolymer, an aromatic hydrocarbon copolymer having a polymerizable double bond, and an aliphatic hydrocarbon copolymer having a polymerizable double bond. . These may be a binary copolymer or a ternary or higher multi-component copolymer.

  Among the above copolymers, an aromatic hydrocarbon having a polymerizable double bond and a fat having a polymerizable double bond from the viewpoint of hardly causing separation even when the resulting coating composition is stored for a longer period of time. Polymers with group hydrocarbons are preferred. Specifically, the polymer includes styrene / isoprene copolymer, styrene / butadiene copolymer, styrene / methylstyrene / indene copolymer, ethylene / propylene / styrene copolymer, butylene / ethylene / styrene copolymer. Examples include polymers, butylene / ethylene / propylene copolymers, isoprene / pentadiene copolymers, decene / butene copolymers, and the like. In these copolymers, hydrogen may be appropriately added in the molecule. In addition, these copolymers may be added to a hydrocarbon solvent such as hydrogenated polydecene or polybutene, or a fat or oil such as jojoba oil to form a gel. By making the copolymer into such a gel-like body, handleability is improved.

  The method for polymerizing the copolymer is not particularly limited, and general-purpose polymerization methods can be appropriately employed. As the polymerization method, for example, bulk polymerization, solution polymerization, emulsion polymerization and the like are appropriately employed depending on the purpose and application. The polymerization initiation method in the above polymerization reaction may be performed by supplying energy necessary for initiation of polymerization from an active energy source such as heat, electromagnetic waves (infrared rays, ultraviolet rays, X-rays, etc.), electron beams, etc. If an agent is used in combination, the energy required for initiation of polymerization can be greatly reduced, and reaction control is facilitated, which is preferable.

  The content of the non-water thickener containing the above copolymer is not particularly limited as long as the oily solvent can be appropriately thickened and the separation of the oily solvent can be suppressed. For example, the content of the non-water thickener is preferably 10% by mass or more, and more preferably 15% by mass or more in the coating composition. Moreover, it is preferable that content of a non-water thickener is 50 mass% or less, and it is more preferable that it is 45 mass% or less. When content of a non-water thickener is less than 10 mass%, there exists a tendency for a coating composition to become easy to isolate | separate. On the other hand, when the content of the non-water thickener is less than 50% by mass, the feeling of use is likely to be lowered, such as being easily sticky.

<Oil solvent>
The oily solvent is a component for dispersing the exothermic component and blocking the exothermic component and moisture to prevent the exothermic component from generating heat. Since the oily solvent of the present embodiment is thickened by the above-described non-water thickener, it is possible to uniformly disperse the exothermic component while blocking moisture, and to separate the resulting coating composition. Can be suppressed.

  The oily solvent is not particularly limited. For example, hydrocarbon solvents such as liquid paraffin, light isoparaffin, polybutene, decane, dodecane, hexadecane, octadecane, isohexadecane, squalane, squalene, isopropyl myristate, cetyl ethylhexanoate, etc. Examples include ester solvents, silicone solvents such as methylpolysiloxane, vegetable oil solvents such as olive oil, and the like. Among these, the oil-based solvent is preferably a hydrocarbon solvent from the viewpoint that it is difficult to react with the exothermic component and is excellent in stability.

  The content of the oily solvent is not particularly limited as long as the exothermic component can be uniformly dispersed. As an example, the content of the oily solvent is preferably 30% by mass or more, and more preferably 35% by mass or more in the coating composition. Moreover, it is preferable that it is 70 mass% or less in an application | coating composition, and, as for content of an oil-based solvent, it is more preferable that it is 65 mass% or less. When the content of the oily solvent is less than 30% by mass, the exothermic component tends to be difficult to disperse uniformly. Therefore, such a coating composition is difficult to apply at a uniform concentration on the application site such as the skin and the hair, and tends to cause variation in the warming effect. On the other hand, when the content of the oily solvent exceeds 80% by mass, the coating composition tends to be easily separated from the oily solvent by long-term storage.

<Other ingredients>
The coating composition according to the present embodiment includes, in addition to the above-described exothermic component, non-aqueous thickener, and oily solvent, other surfactants, active ingredients, alcohols, foaming agents, and the like depending on applications and purposes. Components can be appropriately contained. These components are used in appropriate amounts within a range that does not impair the effects of the coating composition of the present embodiment.

(Surfactant)
The surfactant is used for the purpose of adjusting the dispersibility of the exothermic component, adjusting the contact state with moisture after coating, adjusting the degree of heat generation, and facilitating washing after use. Surfactants include sorbitan fatty acid ester, glycerin fatty acid ester, polyoxyethylene sorbitan fatty acid ester, polyoxyethylene glycerin fatty acid ester, polyethylene glycol fatty acid ester, polyoxyethylene sorbit fatty acid ester, polyoxyethylene alkyl ether, polyoxyethylene poly Oxypropylene alkyl ether, polyoxyethylene castor oil / hardened castor oil, polyoxyethylene lanolin alcohol, polyoxyethylene alkylamine, alkyldimethylamine oxide solution, polyoxyethylene fatty acid amide, fatty acid alkylolamide, alkyl glucoside, alkyl polyglucoside , Polyoxyethylene / methylpolysiloxane copolymer, polyoxypropylene / methylpoly Rokisan copolymer, poly (oxyethylene-oxypropylene) methylpolysiloxane copolymer, etc. are exemplified.

(Active ingredient)
The active ingredient is used for the purpose of imparting a desired effect to an application site such as skin and hair. Active ingredients include vitamins such as retinol and dl-α-tocopherol, anti-inflammatory agents such as glycyrrhetinic acid, anti-oxidants such as α-tocopherol and dibutylhydroxytoluene, anticoncentrations such as miconazole nitrate, sulconazole nitrate, and clotrimazole. Antifungal agents such as fungicides, methyl salicylate, indomethacin, felbinac, ketoprofen, etc., refreshing agents such as l-menthol, camphor, lauryl methacrylate, geranyl crotolate, acetophenone myristate, benzyl acetate, benzyl propionate, methyl phenylacetate, etc. Deodorant ingredients, ethyl hexyl paramethoxycinnamate, isopropyl paramethoxycinnamate, octyl paramethoxycinnamate, octyl dimethoxybenzylidene dioxoimidazolidine propionate, Ultraviolet absorbers such as hexyl diethylaminohydroxybenzoylbenzoate, t-butylmethoxydibenzoylmethane, ethylhexyltriazone, octoclerin, oxybenzone, hydroxybenzophenonesulfonic acid, sodium dihydroxybenzophenonesulfonate, dihydroxybenzophenone, paraaminobenzoic acid, titanium oxide, oxidation Examples include ultraviolet scattering agents such as zinc, and fragrances.

(alcohol)
Alcohol is used as a solvent for an active ingredient that does not dissolve in an oily solvent. Examples of the alcohol include monohydric alcohols such as ethanol and isopropanol, polyhydric alcohols such as propylene glycol, 1,3-butylene glycol, and glycerin.

  The foaming agent is used for the purpose of reacting when mixed with a hydrophilic preparation to be described later to foam the coating composition for easy application and adjusting the warming effect. Examples of the foaming agent include carbonates such as sodium bicarbonate and sodium bicarbonate.

  Returning to the description of the coating composition, the method for preparing the coating composition of the present embodiment including the above composition is not particularly limited. As an example, the coating composition of the present embodiment can be prepared by adding a non-aqueous thickener containing the above-described hydrocarbon copolymer to an oily solvent and further dispersing an exothermic component. it can.

  The viscosity of the coating composition to be obtained is not particularly limited as long as the exothermic preparation is uniformly dispersed and the oily solvent does not separate. As an example, the viscosity of the coating composition is 5,000 mPa / s or more, preferably 10,000 mPa · s or more at 20 ° C. Further, the viscosity of the coating composition is 50,000 mPa · s or less and 40,000 mPa · s or less. By adjusting the viscosity of the coating composition to 5,000 to 50,000 mPa · s, the coating composition is difficult to separate the oily solvent and the exothermic component is easily dispersed uniformly over a long period of time. Further, the coating composition is not solidified even when stored in a low temperature environment such as 5 ° C., and can be discharged when filled in an aerosol container to make an aerosol product.

  As described above, according to the coating composition of the present embodiment, the exothermic preparation is uniformly dispersed in the oily solvent by the non-aqueous thickener containing the hydrocarbon copolymer. Therefore, the obtained coating composition is unlikely to cause separation even when stored for a long period of time. As a result, for example, when a discharge product in which a container is filled with such a coating composition is prepared and the coating composition is applied to an application site such as the skin or the hair, the applied coating composition is discharged. There is no variation in the degree of heat generated each time, and a stable warm feeling can be imparted to the application location.

[Discharge product]
The above-mentioned coating composition can be used as a general-purpose discharge product that can be filled in a container and can appropriately discharge the filled coating composition. Below, an example (1st Embodiment-4th Embodiment) of the discharge product filled with the composition for application | coating is demonstrated with reference to drawings.

(First embodiment)
FIG. 1 is a schematic cross-sectional view of a discharge product 1 of the present embodiment. The discharge product 1 of the present embodiment includes an aerosol container, and the aerosol container includes a container main body 2 (first container) including a flexible inner bag 21 (an example of a second container provided in the first container). 1 container), a valve 6 fixed to the opening of the container body 2, and a discharge member 7 attached to the valve 6.

  The container body 2 has a bottomed cylindrical shape, and a bead portion for fixing the valve 6 to the opening is formed. The container body 2 is not particularly limited as long as it does not transmit moisture and has pressure resistance. For example, a metal such as aluminum or tin, a synthetic resin such as polyethylene terephthalate, pressure glass, or the like is used. In addition, when a synthetic resin is used, it is preferable that the container main body 2 is provided with a vapor deposition film of carbon or silica on the inner surface and / or the outer surface. Thereby, the permeation | transmission of a water | moisture content is suppressed.

  The inner bag 21 is a flexible bag that contracts due to a pressure difference, and is used by being inserted into the container body 2. The inner bag 21 is hermetically filled with the coating composition described above according to an example of a manufacturing method described later. The inner bag 21 is formed in a bottomed cylindrical shape with a single layer of a synthetic resin such as polyethylene, polypropylene, ethylene-vinyl alcohol copolymer resin, polyamide, or fluororesin, and a laminate thereof. The inner bag 21 may be a pouch container in which a sheet of synthetic resin or metal foil is formed in a bag shape.

  The valve 6 includes a mounting cup 22 that is crimped (or clinched) to the bead portion of the container body 2, a housing 23 that is held in the center of the mounting cup 22, and a stem 24 that is accommodated in the housing 23 so as to be movable up and down. A stem rubber 26 for opening and closing a stem hole 25 formed in the stem 24 and a spring 27 that constantly biases the stem 24 upward so that the stem hole 25 is sealed by the stem rubber 26 are provided. In addition, the tilt type valve | bulb which makes the stem 24 tiltable and the stem hole 25 is open | released when it tilts and can discharge the coating composition 4 may be employ | adopted.

  The discharge member 7 is a member for discharging the coating composition 4 filled in the inner bag 21. The discharge member 7 is attached to the stem 24 of the valve 6 and has a passage 28 that communicates from the valve 6 to the discharge hole 5.

  The discharge product 1 is manufactured using such an aerosol container. For example, in the discharge product 1, first, the coating composition 4 is filled in the inner bag 21. Next, a pressurizing agent filling portion 3 which is a space between the inner bag 21 and the container main body 2 is filled with a pressurizing agent 3a such as a compressed gas or a liquefied gas (an example of the pressurizing agent filled in the first container). Is done. Thereafter, the mounting cup 22 of the valve 6 is fixed to the bead portion of the container body 2, and the discharge member 7 is attached to the stem 24 of the valve 6.

  As the compressed gas, nitrogen gas, carbon dioxide gas, nitrogen suboxide gas, compressed air, or the like is used. The filling amount of the compressed gas is preferably such that the pressure inside the aerosol container is 0.3 to 1.0 MPa. When the filling amount is less than 0.3 MPa, there is a tendency that the entire amount of the coating composition 4 cannot be discharged. On the other hand, when the filling amount exceeds 1.0 MPa, the internal pressure is high even after the entire amount of the coating composition 4 is discharged, and the safety at the time of disposal may be lowered.

  As the liquefied gas, liquefied petroleum gas, dimethyl ether, hydrofluoroolefin, a mixture thereof and the like can be used. The filling amount of the liquefied gas is preferably 0.1 to 10% by weight.

  In such a discharge product 1, for example, when the user pushes down the discharge member 7, the valve 6 is opened, and the inside of the inner bag 21 communicates with the atmosphere. At this time, the inner bag 21 is contracted by the pressure of the pressurizing agent 3a, and the coating composition 4 filled in the inner bag 21 is discharged to the outside.

  Here, in the conventional discharge product, the oil component (such as an oily solvent) of the coating composition is likely to be separated. Therefore, prior discharge products, for example, it is necessary to uniformly re-disperse the oil component by shaking up and down before use, and when the coating composition is hermetically filled, such as oil-based solvent The oil component was difficult to be redispersed even when shaken up and down. However, according to the discharge product 1 of the present embodiment, the coating composition 4 is unlikely to separate even if stored for a long period of time, as described in detail in the above embodiment. Therefore, the discharge product 1 does not need to be shaken up and down before use, for example. Moreover, since the discharge product can be filled with the coating composition in a sealed state, the coating composition is appropriately discharged in any direction. Further, in the discharge product 1 of the present embodiment, when the inside of the container body 2 communicates with the outside, the inner bag 21 is compressed by the pressure of the pressurizing agent 3a in the container body 2 and is filled in the inner bag 21. The coating composition 4 is discharged. On the other hand, the discharge product 1 of the present embodiment is filled in the container body 2 because the inside and outside of the inner bag 21 are shut off during storage, and the inner bag 21 is provided in the container body 2. Pressurized by the pressurizing agent 3a. For this reason, moisture in the air hardly enters the inner bag 21 during storage, and the airtightness is highly maintained. As a result, the discharge product 1 of this embodiment can prevent the coating composition 4 from reacting with moisture and generate heat during storage, and can generate heat appropriately only when the coating composition 4 is discharged. .

  An adsorbent that adsorbs moisture such as silica gel and zeolite may be provided in the space between the container body 2 and the inner bag 21. In this case, since the moisture in the space is further reduced, the coating composition 4 is stored more stably without reacting with moisture.

  The discharge product 1 of the present embodiment may be applied directly to the skin or hair by applying the coating composition 4 directly on the skin or hair, and may be heated by moisture contained in the skin or hair or moisture in the air. You may make it generate | occur | produce by wetting a location previously with water | moisture content and apply | coating. Further, after coating, moisture may be applied to generate heat.

  The exothermic effect obtained by such a discharge product 1 is preferably such that the skin feels warm when used in an application site such as skin or hair. For example, the temperature rise by the coating composition 4 is 5 ° C. It is preferable that the temperature be 10 ° C. or higher. Moreover, it is preferable that it is 50 degrees C or less, and, as for the raise temperature by the composition 4 for coating, it is more preferable that it is 40 degrees C or less. Further, the duration of the heat generation effect can be adjusted according to the use or purpose of the discharged product. As for the duration, for example, a state where the temperature has increased by 10 ° C. or more is preferably sustained for 60 seconds or more, and more preferably 120 seconds or more.
