Problems solved by technology

[0003] In such aerosol products for foam formation, in order to obtain good foam formation properties and foam stability of the discharge, as a propellant, liquefied petroleum gas such as liquefied petroleum gas or dimethyl ether is used, and there are problems such as the following: due to the liquefaction Gas is flammable, so it may be dangerous to handle depending on the use environment, or an explosion accident may occur when the aerosol container is discarded
[0005] However, in such a composition, since it is necessary to preliminarily fill the organic acid-containing composition and the bicarbonate-containing substance composition in a container that is sealed by a cover such as a tube-shaped container or a cup-shaped container, the application In this case, it is necessary to carry out cumbersome work of taking out and mixing the composition from each container
And there is the following problem: Since the amount taken out from each container cannot be adjusted, it may not be mixed at an appropriate mixing ratio, and in addition, since the composition in the container is exposed to the air every time it is used, it may not be possible after a long period of time. obtain sufficient storage stability

Embodiment 1～ Embodiment 12 and comparative example 1

[0149] (Preparation of the first stock solution composition)

[0150] First, the paste base "EMACOL HD2146" (manufactured by Sanei Chemical Co., Ltd.) is heated at a temperature range of 80 to 85°C to obtain an oily solution (oil phase). On the other hand, purified water and Polyoxyethylene lauryl ether "BL-9EX" (manufactured by Nikko Chemicals Co., Ltd.) as an active agent is mixed with other raw materials for the first stock solution composition if necessary, and heated at a temperature range of 80 to 85°C , thus obtaining an aqueous solution (aqueous phase).

[0151] Next, the obtained oily solution (oil phase) was stirred under the condition of a stirring speed (rotational speed) of 600 rpm using a blade stirrer, and the obtained water-soluble solution (water phase) was slowly added to the oily solution, thereby Prepare emulsion. Then, after cooling the obtained emulsion until the liquid temperature became 30° C. or lower, an organic acid was added and stirred at a stirr...

Embodiment 1

[0159] In Example 1, in the filling space for the first stock solution (inside the first inner bag) of the dual-structure container, instead of the first stock solution composition, it is filled in the process of preparing the first stock solution composition related to Example 1. , and in the filling space for the second stock solution (in the second inner bag), instead of the second stock solution composition, the emulsion obtained in the preparation process of the second stock solution composition related to this Example 1 is filled , except that, a comparative aerosol product was produced in the same manner as in Example 1.

[0160]

[0161] Regarding each of the aerosol products produced in Examples 1 to 12, Comparative Example 1, and Comparative Example 2 described above, the foaming property of discharge was evaluated by the following method. The results are shown in Table 1 and Table 2.

Abstract

The purpose of the present invention is to provide a foam-forming aerosol product that can be applied with a high degree of safety regardless of the usage environment, that has excellent storage stability, and that is capable of easily forming a satisfactory foam. This foam-forming aerosol product is characterized by being provided with a double-structure container provided with a discharge mechanism having a propellant filling space and two stock liquid filling spaces, the discharge mechanism for simultaneously discharging contents filled into the two stock liquid filling spaces, a propellant comprising a compressed gas being filled into the propellant filling space, a first stock liquid composition containing 0.5-15.0% by mass of an organic acid being filled into a first stock liquid filling space, a second stock liquid composition containing 0.5-15.0% by mass of a bicarbonate substance being filled into a second stock liquid filling space, and a foam being formed by mixing of the first stock liquid composition discharged from the first stock liquid filling space and the second stock liquid composition discharged from the second stock liquid filling space.

Description

technical field [0001] The present invention relates to foam-forming aerosol articles. Background technique [0002] Conventionally, as a kind of aerosol product, it is known that an aerosol composition including a stock solution containing an active ingredient and the like and a propellant is filled in an aerosol container including a pressure-resistant container equipped with a jet valve, and the discharge is passed through The propellant contained in it vaporizes to form a foam, thereby obtaining a foamy discharge. [0003] In such aerosol products for foam formation, in order to obtain good foam formation properties and foam stability of the discharge, as a propellant, liquefied petroleum gas such as liquefied petroleum gas or dimethyl ether is used, and there are problems such as the following: due to the liquefaction Gas is flammable, so it may be dangerous to handle depending on the usage environment, or there may be an explosion accident when the aerosol container i...
