Description

  The present invention relates to aerosol compositions. More particularly, the present invention relates to an aerosol composition that forms a frozen product when sprayed, and can be colored in a desired color.

  Patent Document 1 discloses an aerosol composition that contains an aqueous stock solution containing a surfactant, a dye, and water and a liquefied gas, and forms a frozen product upon injection.

Japanese Patent Laid-Open No. 11-5715

  However, although the composition for aerosol in Patent Document 1 is colored with a pigment, the color of the frozen product becomes light and there is a problem that the desired color is not exhibited. As a result of studying to solve this problem, this aerosol composition cooled the aqueous stock solution by the heat of vaporization of the liquefied gas to form a frozen substance when injected, but at the same time the surrounding moisture was also cooled, and the freezing It was found that the surface of the object became frosty and white.

  Therefore, the present invention is an aerosol composition that forms a frozen product when sprayed, and the frozen product is less likely to be white, and a frozen product colored in a desired color is obtained. In particular, the frozen composition and the aerosol composition in the aerosol container An object of the present invention is to provide an aerosol composition exhibiting a close color.

  The aerosol composition of the present invention is an aerosol composition containing an aqueous stock solution containing a surfactant and water, a liquefied gas, and a coloring component, and forms a frozen product on the injection surface when jetted. It is characterized by coloring the liquefied gas.

  The colored component is preferably an oil-soluble dye that dissolves in a liquefied gas.

  Further, the present invention is an aerosol product in which the aerosol composition is filled in an aerosol container, the container body of the aerosol container has translucency, and the aerosol composition filled inside can be visually recognized from the outside. It relates to aerosol products.

  According to the present invention, the propelled material forms a frozen material, and the frozen material is hardly whitened, and a frozen material colored in a desired color is obtained. In particular, the frozen material and the aerosol composition in the aerosol container have similar colors. The aerosol composition shown can be provided.

  Furthermore, by filling the aerosol composition of the present invention into an aerosol container provided with a translucent container body whose inside can be visually recognized, it is easy for the user to imagine the color of the propellant, and An aerosol product that can produce an aesthetic appearance by color and the color of the propellant, and an effect that can be imaged from color (for example, when a fragrance is blended, a consumer can image a scent from the color). Can do.

When the aerosol composition in the aerosol container is injected, the aqueous stock solution is cooled by the heat of vaporization of the liquefied gas to form a frozen product.

  Here, in the case of an aerosol composition using a non-colored liquefied gas, the one in which the surrounding water is frozen is likely to adhere to the surface of the frozen material in the form of frost and becomes white, and the color of the colored component is difficult to be shown. . However, according to the aerosol composition of the present invention, when the liquefied gas is vaporized by injecting the aerosol composition, the colored component that has colored the liquefied gas adheres so as to cover the surface of the frozen material without being vaporized.
