Japanese Patent No. 4102757

  The present invention includes a powder that can stably carry an active ingredient in a porous powder and that can uniformly obtain the effect of the active ingredient by applying heat or force due to friction to the discharged powder. An object is to provide an aerosol composition.

  The powder-containing aerosol composition of the present invention is a powder-containing aerosol composition containing a porous powder and a liquefied gas, wherein the porous powder has a bulk density of 10 to 300 g / l, and the porous powder contains a solvent. And a powder-containing aerosol composition containing 5 to 70% by mass of a supporting powder supporting an active ingredient and 30 to 95% by mass of the liquefied gas.

  The supported powder preferably contains 4 to 40% by mass of porous powder, 50 to 95% by mass of solvent, and 1 to 20% by mass of active ingredient.

  It is preferable that the surface of the porous powder is hydrophobic, the solvent is a water-soluble solvent, and the active ingredient is a hydrophilic active ingredient.

  The water-soluble solvent is preferably a mixture of water and a polyhydric alcohol.

  The active ingredient is preferably a styling resin.

  The liquefied gas is preferably a lipophilic liquefied gas or a hydrophilic liquefied gas.

  According to the present invention, a powder-containing aerosol containing 5 to 70% by mass of a supported powder in which a solvent and an active ingredient are supported on a porous powder having a bulk density of 10 to 300 g / l, and 30 to 95% by mass of the liquefied gas. By making the composition, the active ingredient can be stably supported in the porous powder, so that even when stored for a long period of time or in a high-temperature environment, a discharged product with a uniform component can be obtained. Can be obtained. In addition, the active ingredient supported on the support powder tends to ooze out of the porous powder due to the temperature rise, but the discharge immediately after discharge is cooled and stably supported by the heat of vaporization of the liquefied gas, Adds frictional force or body heat to the discharged powder, so that the active ingredient oozes out and a waxy or creamy discharged product with excellent usability is obtained. Aerosol compositions can be provided.

  When the carrier powder contains 4 to 40% by mass of porous powder, 50 to 95% by mass of solvent, and 1 to 20% by mass of active ingredient, the powder state is maintained even when the solvent and the active ingredient are supported. It becomes easy.

  When the surface of the porous powder is hydrophobic, the solvent is a water-soluble solvent, and the active ingredient is a hydrophilic active ingredient, the solvent and the active ingredient can be easily removed from the supported powder by spreading the discharge. It tends to protrude and become waxy or creamy.

  When the water-soluble solvent is a mixture of water and a polyhydric alcohol, the active ingredient can be stably supported on the porous powder.

  When the active ingredient is a styling resin, the carrier powder is provided with adhesiveness, and when sprayed, it is prevented from scattering on the coated surface and easily adheres.

  When the liquefied gas is an oleophilic liquefied gas, the oleophilic liquefied gas can be pressurized from the outside of the porous powder to confine the water-soluble solvent and the water-soluble active ingredient in the pores, and the stability is improved. .

  Further, when the liquefied gas is a hydrophilic liquefied gas, it is easy to spread because it foams after adhering to a powder, and it becomes transparent immediately and does not remain white.

  The powder-containing aerosol composition of the present invention is a powder-containing aerosol composition containing a porous powder and a liquefied gas, and comprises a carrier powder and a liquefied gas in which a predetermined porous powder carries a solvent and an active ingredient. It is characterized by containing a fixed amount.

  The porous powder is a powder having a large number of pores on the surface, and is used as a supporting powder in which a solvent and an active ingredient are supported on the pores of the porous powder. An aerosol composition containing a porous powder, a solvent, and an active ingredient as a carrier powder is discharged in a powder form, but when the friction force or body heat is applied to the powder, it is effective with the solvent carried. The exudation of the components can be obtained, and an excellent discharge feel can be obtained, and further, the powder can be prevented from rising during discharge.

  Examples of the porous powder include silica, aluminum oxide, and titanium oxide. Among them, it is preferable to use silica prepared by a dry method from the viewpoint that a large amount of solvent can be easily adsorbed and a powder state can be maintained.

  As the porous powder, a surface-treated hydrophobic powder or an untreated hydrophilic powder can be used according to the active ingredient to be supported and the properties required of the aerosol composition. Examples of the surface treatment include hydrophobic treatment with dimethyl silicone oil, octylsilane, methacryloxysilane, alkylsilyl and the like. In particular, by using porous powder that has been subjected to hydrophobic treatment, the effect of the present invention that the active ingredient can be stably supported in the porous powder can be exhibited, and the active ingredient can be easily made from the discharged powder. Since it exudes, it can be set as the powder containing aerosol composition excellent in a usability | use_condition.

  The bulk density of the porous powder is 10 to 300 g / l, preferably 20 to 200 g / l, and more preferably 30 to 150 g / l. When the bulk density is less than 10 g / l, there is a tendency that the amount capable of supporting the solvent and the active ingredient is reduced while maintaining the powder state. On the other hand, when it exceeds 300 g / l, the powder is too light and is difficult to mix with the solvent and the active ingredient and tends to be difficult to carry. In addition, let the bulk density of the porous powder in this invention be a bulk density measured by the method defined by ISO787-11.

The specific surface area of the porous powder is preferably 20 to 400 m ² / g, more preferably 30~300m ² / g, more preferably 50 to 250 m ² / g. When the specific surface area is less than 20 m ² / g, the supported amount of the solvent and the active ingredient tends to decrease. Moreover, when it exceeds 400 m < ² > / g, there are many small pores and there exists a tendency for the solvent and active ingredient carry | supported by the pores to ooze out easily. In addition, let the specific surface area of the porous powder in this invention be a specific surface area computed by BET method from the adsorption isotherm using nitrogen.

  The content of the porous powder in the support powder is preferably 4 to 40% by mass, and more preferably 5 to 35% by mass. When the content of the porous powder is less than 4% by mass, it tends to be difficult to maintain the powder state. Moreover, when it exceeds 40 mass%, even if it adds friction to the discharged powder, it is hard to ooze out and there exists a tendency for it to become difficult to change to wax form or cream form.

  The said solvent is used as a solvent which melt | dissolves the active ingredient mentioned later. Examples of the solvent include aqueous solvents such as water and alcohols, and oily solvents such as hydrocarbon oil, ester oil, and silicone oil.

  Examples of the water include purified water and ion exchange water. Examples of the alcohols include monovalent lower alcohols such as ethanol and isopropanol, and polyvalents such as ethylene glycol, propylene glycol, 1,3-butylene glycol, glycerin, diethylene glycol, dipropylene glycol, polyethylene glycol, and polypropylene glycol. Examples include alcohol.

  Examples of the hydrocarbon oil include liquid paraffin, squalene, squalane, and isoparaffin. Examples of the ester oil include diisopropyl adipate, isopropyl myristate, isopropyl palmitate, cetyl octanoate, octyldodecyl myristate, butyl stearate, myristyl myristate, decyl oleate, cetyl lactate, isocetyl stearate, diisobutyl adipate, Examples include diisopropyl sebacate, diethoxyethyl succinate, diisostearyl malate, and the like. Examples of the silicone oil include methylpolysiloxane, octamethylcyclotetrasiloxane, decamethylcyclopentasiloxane, methylcyclopolysiloxane, octamethyltrisiloxane, decamethyltetrasiloxane, and methylphenylpolysiloxane.

  Among them, it is preferable to use an aqueous solvent from the viewpoint that it is easy to mix an active ingredient, easily oozes when the discharged powder is rubbed, and easily changes to a waxy or creamy form, and particularly water and a polyhydric alcohol. And a mixture thereof. Moreover, when using the mixture of water and a polyhydric alcohol as said solvent, 1 / 99-40 / 60 is preferable and, as for the content ratio (mass ratio) of water and a polyhydric alcohol, 3 / 97-30 / 70 is more preferable. When the water content ratio is less than 1, it tends to be sticky, and when it is greater than 40, the discharged product is difficult to maintain a powder form and tends to change into a cream form before applying friction.

  The content of the solvent in the carrier powder is preferably 50 to 95% by mass, and more preferably 60 to 92% by mass. When the content of the solvent is less than 50% by mass, even if friction is applied to the discharged material, it does not easily ooze out, and tends to hardly change into a waxy or creamy form. Moreover, when it exceeds 95 mass%, it is hard to maintain a powder form and there exists a tendency which changes to liquid before applying friction.

  The active ingredient is used for the purpose of being dissolved in a solvent and supported on a porous powder, and exhibiting an effect by exuding from the porous powder after ejection.

  Examples of the active ingredient include polyvinyl alcohol, vinyl pyrrolidone-vinyl acetate copolymer, (acrylates / alkyl acrylate / methacrylic acid ethylamine oxide) copolymer, vinyl pyrrolidone / N, N-dimethylaminoethyl methacrylic acid copolymer diethyl Sulfate, (octylamide acrylate / hydroxypropyl acrylate / butylaminoethyl methacrylate) copolymer, N-vinylpyrrolidone / methacrylamide / N-vinylimidazole copolymer, (dimethylacrylamide / hydroxyethyl acrylate / methoxy acrylate) Ethyl) copolymer and other styling resins; collagen, xylitol, sorbitol, hyaluronic acid, caronic acid, sodium lactate, DL-pyrrolidone carboxylate, keratin, Moisturizers such as zein, lecithin and urea; preservatives such as paraoxybenzoate and phenoxyethanol; bactericidal disinfectants such as benzalkonium chloride, benzethonium chloride, chlorhexidine chloride, photosensitizer and parachlormetacresol; glycine, alanine and leucine , Serine, tryptophan, cystine, cysteine, methionine, aspartic acid, glutamic acid, arginine and other amino acids; water-soluble vitamins such as calcium pantothenate, magnesium ascorbate and sodium ascorbate; refreshing agents such as menthol and camphor; Water-soluble active ingredients that are soluble in the aforementioned aqueous solvent, such as retinol, retinol, retinol acetate, retinol palmitate, dl-α-tocopherol, tocopherol acetate, tocopherol And oil-soluble vitamins such as tocopherol nicotinate; UV absorbers such as hexyl diethylaminohydroxybenzoyl benzoate and 2-ethylhexyl paramethoxycinnamate; and lipophilic active ingredients that are soluble in the aforementioned oil-based solvents such as oil-soluble fragrances . In particular, it is preferable to use a styling resin from the viewpoint that when the carrier powder is imparted with viscosity and discharged in the form of a spray, it does not scatter and easily adheres.

  1-20 mass% is preferable and, as for content of the active ingredient in support | carrier powder, 2-15 mass% is more preferable. When the content of the active ingredient is less than 1% by mass, the effect of the active ingredient tends to be difficult to obtain. Moreover, when it exceeds 20 mass%, there exists a tendency for the carry | supported active ingredient to ooze out easily in an aerosol composition.

  The carrier powder is one in which a solvent and an active ingredient are carried in pores on the surface of the porous powder. In addition, what is carry | supported by the porous powder may be adsorb | sucked by the pore of porous powder, or may be inserted.

  The method for producing the supported powder is not particularly limited. For example, the active ingredient is dissolved or dispersed in a solvent, added to the porous powder, mixed and stirred with a mixer, etc. It can be prepared by loading the components.

  The content of the carrier powder is 5 to 70% by mass in the powder-containing aerosol composition, and more preferably 7 to 60% by mass. When the content of the supported powder is less than 5% by mass, the powder tends to be difficult to adhere. Moreover, when it exceeds 70 mass%, it tends to be easily clogged in the discharge passage.

  The liquefied gas is a liquid having a vapor pressure in the pressure-resistant container, acts as a propellant, and can be vaporized when discharged under atmospheric pressure to cool the discharge.

  Examples of the liquefied gas include lipophilic liquefied gas and hydrophilic liquefied gas. Depending on the liquefied gas to be contained, the behavior of the ejected matter (whether foaming is present or the like) changes, so that it can be appropriately selected according to the use and purpose of the powder-containing aerosol composition.

  Examples of the oleophilic liquefied gas include liquefied petroleum gas which is propane, normal butane, isobutane and a mixture thereof, trans-1,3,3,3-tetrafluoroprop-1-ene, trans-2,3,3, Examples thereof include hydrofluoroolefins such as 3-tetrafluoroprop-1-ene, and mixtures of the liquefied petroleum gas and hydrofluoroolefin.

  By using a lipophilic liquefied gas as the liquefied gas, it is possible to efficiently suppress the seepage of the solvent and active ingredient from the supported powder during storage, especially when using a water-soluble solvent and a hydrophilic active ingredient. The effect is high. In addition, the discharged material is in a cooled powder form immediately after discharge, and by adding frictional force and body heat to this, the solvent and active ingredient in the carried powder ooze out and change into a wax shape or cream shape Shows behavior. There is almost no foaming.

  Examples of the hydrophilic liquefied gas include dimethyl ether.

  When a hydrophilic liquefied gas is used as the liquefied gas, the discharged product is in the form of a cooled powder immediately after the discharge, and then foams due to the solvent or active ingredient in the supported powder exuding due to frictional force or body heat. Furthermore, it shows a behavior of changing to a waxy or creamy state due to foam breaking.

  Content of liquefied gas is 30-95 mass% in a powder containing aerosol composition, and 40-93 mass% is more preferable. When the content of the liquefied gas is less than 30% by mass, the discharge passage tends to be clogged. On the other hand, if it exceeds 95% by mass, the powder is less likely to adhere when ejected and tends to be scattered.

  The powder-containing aerosol composition of the present invention contains a surfactant, an oil component, an active ingredient, and the like in addition to the above-mentioned supported powder (porous powder, solvent, active ingredient) and liquefied gas, depending on the application and purpose. be able to.

  When the surfactant is contained, the content of the powder-containing aerosol composition is preferably 0.1 to 10% by mass, and more preferably 0.5 to 8% by mass. When the content of the surfactant is less than 0.1% by mass, the effect of containing the surfactant tends to be difficult to obtain. On the other hand, when the amount is more than 10% by mass, the surfactant tends to remain on the skin, and the feeling of use tends to be poor, such as stickiness.

  The oil is used for the purpose of adjusting the dispersibility of the carrier powder in the aerosol composition and making the discharged powder easily adhere to the skin. As the oil, hydrocarbon oils, ester oils, and silicone oils mentioned as solvents that can be supported on the porous powder may be used, and solid oils such as fatty acids, higher alcohols, and waxes may be used.

When the content of the oil is less than 0.1% by mass, the effect of the oil tends to be difficult to obtain. On the other hand, when the amount is more than 10% by mass, the feeling of use tends to be lowered, for example, the drying property becomes worse and the stickiness becomes easier.

  The active ingredient is used for the purpose of obtaining an effect other than the effect of the active ingredient carried by the porous powder. As the active ingredient, hydrophilic active ingredients and lipophilic active ingredients mentioned as active ingredients that can be carried on the porous powder described above may be used, and further, powdery active ingredients may be used.
