Description

  The present invention is a post-foamed gel-like hair styling that can be applied uniformly to the target site by being ejected in the form of a gel, foamed by applying a shear stress, foamed into a foam and stretched more than the gel. It is about.

  General gel-like hair dressing is filled in a squeeze tube. As a method for using this gel-like hair styling agent, an appropriate amount of gel is taken and stretched with the palm, and then applied to a target site. Such a gel-like hair styling material has a problem that it is difficult to uniformly apply to a target site.

  On the other hand, cosmetics having a post-foaming property that foams by applying shear stress to the gel state are also provided. For example, the post-foaming gel-like composition described in Patent Document 1 has an alkyl group in the post-foaming gel. By containing glucoside, the defoaming effect is exhibited. Thereafter, in the foamable gel-like composition, the gel can be taken and the foam foamed by applying a shearing stress with a finger can be immediately defoamed while it is immediately applied to styling or spreading on the skin.

Japanese Patent No. 3243158

  In the gel-like hair dressing described above, since the gel is stretched with the palm of the hand and then applied to the target site and stretched, it cannot stretch evenly because it stretches, so after applying the gel, water is applied to the coated surface and stretched again. This causes a problem that it needs to be uniform.

  Moreover, in the technique of patent document 1, since the antifoaming effect was exhibited by containing an alkyl glucoside, even if it was applied immediately after foaming, it immediately disappears while it was stretched. In addition, there is the complexity of having to stretch it. Thus, since it has to apply | coat and extend immediately, when applying after hold | maintaining the foam after foaming, the problem of defoaming cannot be wiped off.

  An object of the present invention is to provide a foamed gel-like hairstyling agent which has good elongation, which can not be obtained in the form of a gel, can be applied uniformly, and has simpleness.

  In order to solve the above-mentioned problems, a post-foaming gel-like hair dressing according to the present invention comprises an active ingredient containing a nonionic resin, a water-soluble polymer and a nonionic surfactant, and an aliphatic hydrocarbon having a boiling point of 40 ° C. or lower. The post-foaming agent is an essential component.

  In the post-foaming gel hair dressing, it is preferable that the base contains 0.1 to 10% by weight of polyvinylpyrrolidone and / or vinyl acetate / vinylpyrrolidone copolymer as a nonionic resin.

  Further, in the post-foaming gel hairdressing agent, 0.5% to 10% by weight of a nonionic surfactant equal to or higher than HLB11, which is blended for the purpose of clarifying and / or foaming the post-foaming hairdressing material. It is preferable to contain by weight.

  Furthermore, in the post-foaming gel hairdressing agent, the aliphatic hydrocarbon as the post-foaming agent has a boiling point in the range of −45 ° C. to 40 ° C., and 0.5 wt% to 10 wt% in the preparation. It is preferable to contain.

  In the post-foaming gel-like hairdressing material 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. Thereby, the elongation is good and uniform coating can be effectively performed.

  Hereinafter, preferred embodiments of the post-foaming gel hairdressing material according to the present invention will be described. The present invention provides a raw material containing 0.1 to 10% by weight of polyvinylpyrrolidone and / or vinyl acetate / vinylpyrrolidone copolymer, 0.5% to 10% by weight of a water-soluble polymer and a nonionic surfactant. The present invention relates to a foamed gel-like hair dressing after blending 0.5 wt% to 10 wt% of a post foaming agent with a body and an aliphatic hydrocarbon having a boiling point of -45 to 40 ° C.

  As a post-foaming gel hair conditioner, the appearance and foamability of the gel are important. This appearance is required to be a transparent gel, and in order to maintain transparency when the raw material and the post-foaming agent are mixed, it is necessary to add a surfactant and solubilize it to make it transparent.

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

  In order to ensure the appearance and foamability as described above, it is necessary to add a surfactant, and a nonionic surfactant is particularly effective.

  The water-soluble polymer is required to have a high viscosity in order to form a stable gel. Common examples of such water-soluble polymers include carboxyvinyl polymers and acrylic acid copolymers, which can be selectively used. In particular, these water-soluble polymers are ionic.

  Since the water-soluble polymer has ionicity, it is preferable to select a nonionic resin as the hair styling component for the purpose of improving the stability of the gel. In particular, the nonionic resin is most preferably polyvinylpyrrolidone and / or vinyl acetate / vinylpyrrolidone copolymer.

  The nonionic resin is preferably contained in the active ingredient in a range of 0.1 wt% to 10 wt%. When the content of the nonionic resin in the active ingredient is 0.1% by weight, the coating is weak, but the feeling of use is improved depending on the use of the hair material. Moreover, when the content rate of the nonionic resin in the raw material is 10% by weight, a tough film can be formed.

  However, even if the nonionic resin is 10% by weight or more depending on the use of the hair styling agent, it is possible to form a tough film, but there is no special difference caused by increasing the blending ratio. Therefore, 10% by weight is sufficient as the upper limit of the content of the nonionic resin in the raw material.

  The post-foaming agent maintains a gel shape when the preparation is discharged, and has a function of foaming when a shear stress is applied. Thus, the post-foaming agent is preferably an aliphatic hydrocarbon having a boiling point that maintains a gel state during discharge and vaporizes and foams when a shear stress is applied.

  As the post-foaming agent having a boiling point in the range of −45 ° C. to 40 ° C. used in the present invention, an aliphatic hydrocarbon composed of normal pentane, isopentane, normal butane, isobutane, propane, etc. is selected alone or in combination. Can be used.

  The post-foaming agent is preferably contained in the preparation in the range of 0.5 to 10% by weight. When the post-foaming agent in the preparation is 0.5% by weight, even if shear stress is applied, foaming does not occur immediately, but since it gradually foams, it is not suitable for use. Further, when the post-foaming agent in the preparation is 10% by weight, foaming can be performed immediately when shearing stress is applied.

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

  The drug substance according to the present invention includes, in addition to components composed of a nonionic resin, a water-soluble polymer and a nonionic surfactant, a lower alcohol, a polyhydric alcohol, an oily substance, a chelating agent, and an ultraviolet absorber depending on applications. , Silicone, pigment, fragrance and the like can be appropriately blended.
