Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention can easily produce a strong foam which can be maintained in a predetermined shape without being defoamed for a long period of time, and can be easily washed with water when defoaming is desired. The present invention relates to an aerosol composition for foaming, which is suitable as a deodorant for kitchen garbage, toilets, etc., and as a foam generating agent for displays.

2. Description of the Related Art Conventionally, foam-forming aerosols have been widely used in many applications such as cleaners for various articles and cosmetics. Conventional foaming aerosol compositions used for such seed-forming aerosols are Since the main ingredient is an anion activator such as soap, an amphoteric activator, or a nonionic activator as a foaming agent, it is possible to generate abundant foam, but it is not possible to retain the generated foam for a long time. However, for example, even if it is used as a deodorant for kitchen garbage or toilets or as a foaming agent for displays, it will defoam in a short period of time, and there is a problem that the effect on deodorization or display cannot be sustained. there were. On the other hand, it has been proposed that the generated foam can be retained for a long time by adding a film-forming agent as an auxiliary agent, but it is not possible to easily wash it off with water, which causes a problem of inconvenience in handling. there were.

[0003]

DISCLOSURE OF THE INVENTION The present invention solves the above-mentioned problems of the prior art and allows the generated foam to retain its shape for a long period of time, and when it is desired to defoam, it is simply washed off with water. It was completed for the purpose of providing an aerosol composition for foaming.

Foaming aerosol composition of the present invention the above object, according to an aspect of has been made to solve the higher alcohols and the carbon number of C ₁₂ -C ₂₀ carbon atoms is C ₁₂ ~
The present invention is characterized in that it comprises a propellant and an adjusted aerosol stock solution containing one or more foaming agents selected from C ₂₂ higher fatty acid polyhydric alcohol esters.

In the present invention, a higher alcohol having a carbon number of C _{12 to} C _{20 and} a C _{12 to} C ₂₂ carbon atom as a foaming agent.
1 selected from higher fatty acid polyhydric alcohol esters
One kind or two or more kinds are used. Generally, higher alcohols and higher fatty acid polyhydric alcohol esters as described above have been conventionally recognized as antifoaming agents for suppressing foaming in aqueous compositions, but the present inventor suppresses foaming. Focusing on the function, when a predetermined molecular weight is selected and used as a foaming agent, it is possible to precisely control the density and size of the foam, and the density is large and the diameter of the foam is large. The present inventors have completed the present invention by discovering that a desired foam that is small and strong and can be easily washed with water can be generated.

Examples of higher alcohols having ₁₂ to ₂₀ carbon atoms include cetyl alcohol (cetanol), stearyl alcohol and olein alcohol. Here, when the carbon number is less than 12, the sufficient foaming suppressing function cannot be exhibited, the density of the bubble is small, and the bubble diameter is large, making it difficult to generate a strong bubble. Since the foaming suppressing function becomes too large and it becomes difficult to generate the foam itself, C has a carbon number of 12 to 20.

Examples of the higher fatty acid polyhydric alcohol ester having a carbon number of C _{12 to} C ₂₂ include glycerin ester, sorbitan ester, glycol ester and sucrose ester. All of these are ester-bonded with 1 to several moles of higher fatty acid, and the molecular weight of the fatty acid to be bonded affects the production of the desired foam, like the above-mentioned higher alcohol. If the fatty acid has less than 12 carbon atoms, the foaming suppressing function cannot be sufficiently exerted, the foam density is small, and the foam diameter is large, making it difficult to form a strong foam, and the fatty acid has 22 carbon atoms.
When it is larger, the foaming suppressing function becomes too large and it becomes difficult to form the foam itself, so that the carbon number of C is 12 to 22.
The range is.

The above-mentioned higher alcohols and higher fatty acid polyhydric alcohol esters can be used alone or in combination of two or more, and the content thereof is 0.5 in the aerosol concentrate. It is necessary to mix it in the range of 20 wt%. Here, if the content is less than 0.5% by weight, the concentration is too low to form the desired foam, and if the content is more than 20% by weight, the viscosity of the aerosol stock solution becomes high. The aerosol itself may not work. Further, the more preferable content range is in the range of 2 to 10% by weight.

In addition to the above-mentioned foaming agent, a dispersion aid such as polyoxyethylene sorbitan fatty acid ester and coconut oil fatty acid diethanolamine for finely foaming the aerosol stock solution, and the foaming agent are dissolved. A solvent such as glycerin for that purpose, and further various flavors and colorants depending on the purpose can be appropriately added, as in the case of a general aerosol composition, and the rest is purified water to form an undiluted aerosol solution. Then, a propellant such as liquefied petroleum gas or monochlorodifluoromethane is added to this aerosol stock solution to obtain a foaming aerosol composition.

The foam produced by such a foaming aerosol composition comprises a higher alcohol having a carbon number of C _{12 to} C ₂₀ or a higher fatty acid polyhydric alcohol ester having a carbon number of C _{12 to} C ₂₂ as a foaming agent. Since the bubble density and the bubble size are accurately controlled, the bubble density is high, the bubble diameter is small, and the bubble is strong. Therefore, the bubble shape can be maintained for a long period of one week or more. In addition, since the foam shape is not retained by the film-forming agent as in the conventional case, the foam can be easily washed off by washing with water, and excellent handleability can be exhibited. Therefore, for example, when used as a deodorant, it is possible to contain the odor generation source for a long period of time, and when used as a foaming agent for display, a decorative body produced for a long period of time is The display effect can be exerted throughout.
