Description

  The present invention relates to a post-foaming cosmetic that foams by being ejected in a gel or cream form (hereinafter referred to as a gel or gel) and applying a shear stress, and in particular, after being ejected to a target site, It is related with the after-foaming cosmetics made to foam by giving a shear stress.

  As the post-foaming cosmetic material, there is a post-foaming shaving gel, which is filled in a pressure-resistant double structure container. As a method of use, there is provided a method in which an appropriate amount of the contents is picked up and applied to the target site and foamed, or stretched and foamed with the palm and then applied to the target site.

  For example, the post-foaming gel-like composition described in Patent Document 1 is such that an antifoaming effect is also exhibited by adding an alkyl glucoside to the post-foaming gel. Thereafter, the foamed gel-like composition can be defoamed immediately after the gel is picked up and foamed by applying shear stress with a finger and immediately applied to the styling or skin.

  Further, for example, the post-foaming pack material described in Patent Document 2 is a mixture of clay minerals in the post-foaming preparation so that the skin surface temperature is not released to the outside air and exhibits a heat insulating effect. .

  Further, for example, the post-foaming aerosol composition described in Patent Document 3 is prepared by blending oleyl alcohol and / or isostearyl alcohol and blending polyoxyethylene oleyl ether, thereby causing a state of the discharged gel-like substance. It has a high transparency.

Japanese Patent No. 3243158 Japanese Patent No. 2805159 Japanese Patent No. 3354678

  In the technique of Patent Document 1, by applying alkyl glucoside to exert an antifoaming effect, even if it is applied immediately after foaming, it immediately disappears while it is stretched. There is a complication that must be stretched with. In this way, if it is not applied and stretched immediately, it will be defoamed, so it is not possible to wipe off the problem of defoaming that it cannot be applied slowly after holding the foam after foaming. .

  In the technique of Patent Document 2, a clay mineral is blended to exert a heat insulating effect. This clay mineral adsorbs oil and dirt such as skin, and forms a film, so it has a heat insulating effect, but it contains water as a formulation, so it feels cool when applied and the heat of vaporization of the foaming agent. Because it takes away from the skin, the problem of giving the skin a feeling of cooling cannot be eliminated.

  In the technology of Patent Document 3, oleyl alcohol and / or isostearyl alcohol is blended with water, soap (fatty acid soap) and a post-foaming agent, and polyoxyethylene oleyl ether is blended and discharged. It exhibits high transparency in the state of a gel substance. In this oleyl alcohol, isostearyl alcohol and polyoxyethylene oleyl ether, the former two components are higher alcohols and the latter is a surfactant. Although this component affects the viscosity of the preparation, it is not a preservative involved in properties such as soap color change, and cannot solve the problem that it cannot be kept in the same state as the initial stage.

  An object of the present invention is to provide a post-foaming cosmetic that can be used for general purposes such as a cleaning cosmetic, a hair cosmetic, a basic cosmetic, an aromatic cosmetic, a tan / sunscreen cosmetic, and a bath cosmetic. It is in.

  Moreover, many types of post-foaming cosmetics can be provided by combining the components to be blended for each application rather than the composition specialized for each application.

  In order to solve the above-mentioned problems, the post-foaming cosmetic composition according to the present invention comprises: a: 0.1% by weight to 3% by weight of a water-soluble polymer comprising a carboxyvinyl polymer and / or an acrylic acid polymer; b: 1 selected from the group consisting of polyoxyethylene hydrogenated castor oil, polyoxyethylene alkyl ether, polyoxyethylene polyoxypropylene alkyl ether, polyoxyethylene sorbitan fatty acid ester, sorbitan fatty acid ester, polyethylene glycol fatty acid ester and polyglycerin fatty acid ester An aqueous raw material containing 0.5 wt% to 10 wt% of a nonionic surfactant in combination of two or more types, c: a polyhydric alcohol, and d: isopentane alone, or isopentane and normal pentane, Isobutane, normal And a post-foaming agent comprising an aliphatic hydrocarbon selectively combined with the aqueous base in the preparation, and 90% to 99.5% by weight of the aqueous base and 10% to 0% of the post-foaming agent. It is characterized by containing 5 wt%.

  In the post-foaming cosmetic, the aqueous base preferably contains a carboxyvinyl polymer and / or an acrylic acid polymer in the range of 0.1% by weight to 3% by weight as the water-soluble polymer. .

  In the above-mentioned post-foaming cosmetic, the aqueous base is used as a nonionic surfactant for emulsification and / or foaming, polyoxyethylene hydrogenated castor oil, polyoxyethylene alkyl ether, polyoxyethylene poly 0.5% by weight or more of one or a combination of two or more selected from the group consisting of oxypropylene alkyl ether, polyoxyethylene sorbitan fatty acid ester, sorbitan fatty acid ester, polyethylene glycol fatty acid ester and polyglycerin fatty acid ester It is preferable to contain in the range of 10 weight%.

  Further, in the above-mentioned post-foaming cosmetic, the post-foaming agent is involved in foaming properties, and is composed of an aliphatic hydrocarbon obtained by isopentane alone or by selectively combining isopentane and normal pentane, isobutane, or normal butane. In particular, isopentane is most preferable in order to obtain good foamability and foaming state.

  Further, the preparation as a post-foaming cosmetic preferably contains 90% to 99.5% by weight of the above aqueous base and 10% to 0.5% by weight of the post-foaming agent. .

  In the post-foaming cosmetic composition according to the present invention, the aliphatic hydrocarbon has a post-foaming function, and is foamed and foamed by being vaporized from the gel-form preparation. As described above, the gel effect is changed to the foam shape to add a visual effect, and the elongation is good and uniform application can be effectively performed.

  Hereinafter, preferred embodiments of the post-foaming cosmetic material according to the present invention will be described. The present invention relates to a post-foaming cosmetic that is discharged in a gel form from a container and generates a shearing stress on the discharged gel, thereby evaporating a post-foaming agent and foaming it into a foam.

  As a post-foaming cosmetic, it is important to maintain a gel-like appearance and to have sufficient foaming properties. In order to maintain the appearance, it is required to discharge in the form of a gel, and in terms of foamability, it is required to foam quickly when a shear stress is applied. That is, the aqueous base and the post-foaming agent are mixed and mixed with a water-soluble polymer and a nonionic surfactant so that the gel shape can be maintained when discharged, and the post-foaming agent is incorporated into the preparation. It needs to be contained.

  In addition, regarding foamability, it is required to make a fine foam, including visual effects, when shear stress is applied to the gel.

  In order to ensure the appearance and foamability of the gel as described above, it is necessary to blend the water-soluble polymer and the surfactant in a preferred ratio.

  As said water-soluble polymer, it is preferable that a formulation can be maintained in the stable gel form. In particular, carboxyvinyl polymer and / or acrylic acid polymer is most preferable.

  The water-soluble polymer is preferably contained in the aqueous base in the range of 0.1% by weight to 3% by weight. When the content of the water-soluble polymer in the aqueous raw material is 0.1% by weight, it is possible to make a gel with increased viscosity and less stickiness. Further, when the content of the water-soluble polymer in the aqueous raw material is 3% by weight, it is possible to make a gel with less fluidity.

  However, when the water-soluble polymer is 3% by weight or more, there is a sticky feeling, which is not preferable as a cosmetic.

  The surfactant is preferably blended with a surfactant capable of containing the post-foaming agent in order to ensure post-foaming properties. As such a surfactant, a nonionic surfactant is particularly preferable.

  The nonionic surfactant is preferably contained in the aqueous raw material in the range of 0.5 wt% to 10 wt%. When the content of the nonionic surfactant in the aqueous raw material is 0.5% by weight, it is possible to ensure the stability of the aqueous raw material depending on the content components. In addition, a stable aqueous base can be obtained even when the content of the nonionic surfactant in the aqueous base is 10% by weight.

  However, when the surfactant is contained in the aqueous material in an amount of 10% by weight or more, the stability of the aqueous material and the amount for containing the post-foaming agent are sufficient, but a sticky feeling is generated. Therefore, 10% by weight is sufficient as the upper limit of the content of the nonionic surfactant in the aqueous raw material.

  Nonionic surfactants are polyoxyethylene hydrogenated castor oil, polyoxyethylene alkyl ether, polyoxyethylene polyoxypropylene alkyl ether, polyoxyethylene sorbitan fatty acid ester, sorbitan fatty acid ester, polyethylene glycol fatty acid ester, polyglycerin fatty acid ester. Is preferred.

  Furthermore, polyoxyethylene hydrogenated castor oil having 10 to 100 polyoxyethylene addition moles as polyoxyethylene hydrogenated castor oil. Also, as polyoxyalkyl ether, polyoxyethylene lauryl ether, polyoxyethylene cetyl ether, polyoxyethylene isocetyl ether, polyoxyethylene stearyl ether, polyoxyethylene isostearyl ether, polyoxyethylene oleyl ether, polyoxyethylene behenyl ether , Polyoxyethylene (12-15) alkyl ether, polyoxyethylene secondary alkyl ether, polyoxyethylene octyldodecyl ether, polyoxyethylene decyl tetradecyl ether. Polyoxyethylene polyoxypropylene alkyl ethers include polyoxyethylene polyoxypropylene decyl tetradecyl ether, polyoxyethylene polyoxypropylene decyl ether, and polyoxyethylene polyoxypropylene cetyl ether. Also, as polyoxyethylene sorbitan fatty acid ester, mono coconut oil fatty acid polyoxyethylene sorbitan, polyoxyethylene sorbitan monopalmitate, polyoxyethylene sorbitan monostearate, polyoxyethylene sorbitan tristearate, polyoxyethylene sorbitan monoisostearate, mono Oleic acid polyoxyethylene sorbitan, trioleic acid polyoxyethylene sorbitan. Examples of sorbitan fatty acid esters include sorbitan monolaurate, sorbitan monopalmitate, sorbitan monostearate, sorbitan monoisostearate, sorbitan sesquistearate, sorbitan tristearate, sorbitan monooleate, sorbitan sesquioleate, and sorbitan trioleate. As polyethylene glycol fatty acid ester, polyethylene glycol monolaurate, polyethylene glycol monostearate, polyethylene glycol monooleate. Examples of polyglycerol fatty acid esters include esters composed of saturated and unsaturated fatty acids having 12 to 18 carbon atoms and glycerol 3 to 10 monomers.

  Although the type of polyhydric alcohol varies depending on the application to be used, the main purpose is to improve the effect of moisturizing agent and feeling of use.

  As a polyhydric alcohol, it is preferable to contain 0.1 to 20 weight% in an aqueous | water-based raw material. The content varies depending on the intended cosmetic, but when the content of the polyhydric alcohol in the aqueous base is 0.1% by weight or less, it is difficult to obtain the intended effect. In addition, when the content of the polyhydric alcohol in the aqueous base is 20% by weight or more, there is a sticky feeling and the usability becomes poor.

  Examples of the polyhydric alcohol include glycerin, diglycerin, polyglycerin, sorbitol, mannitol, maltitol, 1,3-butylene glycol, propylene glycol, dipropylene glycol, polyethylene glycol, xylitol, polyoxyethylene methyl glucoside, DL. -Sodium pyrrolidone carboxylate.

  The post-foaming agent is preferably contained in the preparation in an amount of 0.5 to 10% by weight. When the content of the post-foaming agent in the preparation is 0.5% by weight, foaming does not occur immediately even when a shear stress is applied, but it gradually foams and is not suitable for use. Further, when the content of the post-foaming agent in the preparation is 10% by weight, it becomes possible to foam immediately when a shear stress is applied.

  However, if the amount of the post-foaming agent is 10% by weight or more, the gel cannot be maintained, and a foamy foam is not preferable.

  As the post-foaming agent, it is possible to use isopentane alone or an aliphatic hydrocarbon in which isopentane and normal pentane, isobutane, or normal butane are selectively combined. In particular, isopentane is preferable in order to obtain good foamability and foaming state, and further, it is preferable to use a combination of isopentane, normal pentane, isobutane, and normal butane as a control of foamability.

  In addition to the aforementioned water-soluble polymer, nonionic surfactant, and polyhydric alcohol components, the aqueous base includes lower alcohols, fatty acids, higher alcohols, surfactants, and oily substances depending on the use of the cosmetic. , Inorganic powders, resins, polymers, neutralizers, extracts, menthols, bactericides, anti-inflammatory agents, antihistamines, chelating agents, UV absorbers, silicones, dyes, preservatives, and perfumes.
