Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention generally relates to aerosol products, and a product whose foam is a foam (foam or mousse). This type of product is mainly used for cosmetics (excluding quasi-drugs as defined in the Pharmaceutical Affairs Law). Products are also included), agricultural chemicals, paints, automobile products, household products, and miscellaneous goods.

[0002]

BACKGROUND OF THE INVENTION Foams, in terms of their physical properties,
(A) A small amount of drug solution can be effectively used. (B) Does not sag when applied. (C) The unusual texture of the drug solution is utilized. (D) There is an advantage in application such as covering the coated surface for a long time. From the viewpoint of surface chemistry, the foam is a mixed phase composed of two phases of liquid and gas, and there are various manufacturing methods, but the aerosol type is universal as a product.

Aerosol-type products include mist-like sprayed products, water gun-like water filament-like products, foam-like products in which the sprayed products form foam, and powder products in which only the powder is sprayed instead of the undiluted solution. , All of which are filled in a pressure resistant container with a chemical solution prepared to suit the purpose of use (referred to as an undiluted solution, or in some cases only powder), and a propellant for ejecting the solution.
Overall, it seems to be included in this product.

Thus, in a foam product, the stock solution must contain a foaming agent for producing foam, and most of them are surfactants, and they are anionic type, cationic type, nonionic type.
Both the vinylon type and the polar type are targets for use. However, the surfactant is not immediately compatible with the foaming agent.

In addition, the propellant functions not only to push out the undiluted solution filled in the pressure-resistant container but also to the vaporized gas to form bubbles in the foamed product. This is referred to as "bubble gas". Specifically, liquefied petroleum gas (LPG) and non-specific chlorofluorocarbon are known, and dimethyl ether (DME) has a defoaming effect, so that its use is limited. It cannot be foamed with compressed gas and has never been used before. It is general common knowledge that the amount of liquefied gas blended is 8 to 12 parts by weight per 100 parts by weight of the stock solution.

[0006]

As mentioned above, foam products are reasonably convenient and widely used, but these consumer goods, including their contents, containers, and designs, attract attention from consumers. We are constantly seeking new changes. Not only the efficacy of the contents, but also the unique novelty of the form is a major factor in the sales as a new product. With regard to foamy products as well, it is important that the characteristics of the foam are the slowness of disappearance of the foam, the texture such as novi and smoothness, and the texture such as hardness and gloss. These physical properties are adjusted to suit the purpose of use of the product, but it is also a fact that consumers' tastes, changes in the times, and matching can not be overlooked, and conversely there are physical properties with special changes. Things are adopted and sold on the theme of advertising. Some conventional foam products used the above-mentioned surfactants and propellants to make some changes, but there are limits to this, and the pursuit of new content-type products is in this area. Has become an everlasting challenge in.

[0007]

As a means for solving the problems, the present inventor has conducted numerous experiments and has found a foamy product that exhibits a completely new aspect. That is, the basic gist is (2) alkyl glucoside 0.02 to 5 wt%
And 0.01 to 4 w of higher alcohol which is solid at room temperature
t%, and other surfactants, thickeners, pastes, oils, solvents, powders, lubricants, wetting agents, acid alkalis, pH adjusters, ion sequestering agents, preservatives, colorants, and fragrances as required. , One or two or more, one or two or more active ingredients corresponding to the purpose, and the balance to 100% by weight of water to prepare a stock solution, and one or two of liquefied gas and / or compressed gas. It is an aerosol type foam product in which at least one kind of foaming gas is used, and a concentrate and a foaming gas are filled in a pressure-resistant can. "As a technology developed from that, () foaming gas is liquefied petroleum gas, dimethyl ether, non An aerosol type foam product according to claim 1, which comprises one or two or more of specified chlorofluorocarbon and nitrous oxide, and 4 to 55 parts by weight of the foaming gas is added to 100 w parts of the stock solution. () The foaming gas in the above is 16 to 100 parts by weight of the stock solution.
It is 55 parts by weight, and the filled content is ejected in the form of a mist or a water gun, and a foam is formed on the surface to which the undiluted solution is adhered. () The foaming gas in the above is 0 to 100 parts by weight of the stock solution.
An aerosol type foam product according to claim 1, which comprises 4 parts by weight of liquefied gas and one or more compressed gases of carbon dioxide gas, nitrogen gas, argon gas, helium gas, hydrogen gas and air. () In the above, the solvent to be added to the stock solution is an organic solvent compatible with water, and one or two or more of them is added in an amount of 3 to 97% by weight. ".

Before explaining this content, let me first add to the description of "bubble" objects. In Japanese, a bubble is generally referred to as a fairly wide range, but in this specification, a drug solution forms a foam film, encloses gas to form granules, and a foam mass formed by assembling the particles is called "foam". Or mousse ". Generally, in a two-phase mixed system of gas and liquid, a state in which the amount of liquid is large and air bubbles float alone in the liquid is called “bubble”, but the amount of air bubbles gradually increases and the ratio of liquid decreases, resulting in poor fluidity. The almost completely lost state (for example, the upper layer of beer) is referred to as "sudge". Furthermore, the aggregate of the foam particles in which the proportion of gas increases and the foam particles become finer and solidified is the "form." On the contrary, the aggregates in which the particles of the "balloon" in which the liquid phase forms a foam film and entraps the gas may be considered as "forms", but the present inventor of the aerosol type foams, as a result of microscopic observation, It was revealed that the foam film does not exist.

It is known that a surfactant plays an important role in stabilizing bubbles, that is, a gas-liquid system. It is possible to change the feel of various foams depending on the combination of the type and amount of the surface active agent and the type and amount of gas and the liquid that is a mixture of other components. It is also known that the properties of the foam change depending on the additives to the stock solution. It is clear that the properties of various foams have changed, and adjustments are made to make them suitable for their intended use.However, because of their craftsmanship, systematic academic research is rarely conducted. Not not. Based on the idea of colloidal chemistry, a mixture system of liquid [oil phase] and one liquid [water phase] is an emulsion (emulsification).
It is found to be interesting when compared with the mixed system of [gas phase]-[liquid phase]. If the idea of HLB at the time of emulsification is applied to foaming, it will be ~ 15 for nonionic type.
The vicinity of ~ is the place where foaming is best, and the carbon number of the fatty alkyl group added to the activator of other types of activators is C
No. ₁₂ has the best foaming. As a matter of course, there are reports that the higher the concentration of the active agent, the more stable the foam becomes, and that the mixture of a small amount of oily component (foaming agent) creates a dense foam, The reality is that there are few.

Actually, the evaluation of the form is often entrusted to the so-called "feel" such as appearance and touch, but in general, the sensory test has different details depending on the judge. Therefore, evaluation accompanied by numerical display is desired. . Therefore, the simple methods that can be physically measured include specific gravity, viscosity, defoaming property, particle size distribution, etc.
Specific gravity> Aerosol Sangyo Shimbun 735, <Viscosity> 753
No., <Defoaming property> No. 780, Newspaper No. 735, <Particle size> No. 7
I have just contributed No. 97.

In the case of an aerosol type foam, when the conditions of the foam are the same except that the other conditions are the same and the concentration of the activator in the stock solution is changed, the higher the concentration of the activator, the higher the degree of foaming. It can be considered as it progresses (however, the foam quality is appropriate for each application, and the foam with a high degree of perfection does not necessarily match, for example, the foam of the tire polisher is quick-dissipating and shaving. Foams that are relatively indelible are preferred in foams), and the extent to which the foam properties vary. Unstable foams are close to sudges, have coarse foam masses, large individual bubbles, and feel watery and cold. As the altitude increases, the foam mass does not collapse and disappears, it does not flow like a net, it is uniformly homogeneous and dense, and the whiteness is strongly felt. At higher altitudes, the bubbles feel warmer, harder, and lighter, and when rolled up by the hand, they can even make a ball without sticking to the palm. Where hardness,
Criteria such as stickiness, shape loss, adhesion, flow, smoothness, luster, fineness of texture, evenness of foam particles, inclusion of large air bubbles, and odor are used. The actual measured specific gravity is often heavy, even if the feel is light. However, the more unstable a bubble is, the more it changes moment by moment, and the fact that there are variations due to the presence of individual bubbles in the bubble mass. You should be careful.

Now, the surfactant "alkyl glucoside" which is one of the features used in the present invention will be explained.
This substance has been known since 100 years ago, but its industrial production started around 1992, and when the pollution of synthetic activator was just surfaced, it started to attract attention as a natural activator which can be replaced. It is a substance.

[0013]

[Chemical formula 1]

Its chemical structural formula is as shown in <Chemical formula I>, and it is a nonionic surfactant in which glucose (hydrophilic group) and alkyl group (lipophilic group) are bonded. Sugars obtained by hydrolyzing starch from corn and potatoes and higher alcohols obtained from coconut and beef tallow are reacted to form raw materials from the ecosystem, and thus biodegradable. Data prove that it is easy and environmentally friendly and has no toxicity to living organisms. The degree of polymerization of the glucose group (n: usually 0-4),
Depending on the carbon number of the alkyl group (R: usually C _{8 to} C ₁₈ ), those having several characteristics are commercially available. Typical examples are Henkel's "Blantalen" and Sepik's "Olamix" and "Montanobu".

Next, "higher alcohol which is solid at room temperature" means lauryl alcohol, cetanol, cetostearyl alcohol, stearyl alcohol, behenyl alcohol, aralkyl alcohol, lanolin alcohol, water if the room temperature is defined as 20 ° C. Lanolin alcohol, etc. These include purified products obtained by complete fractionation, but it goes without saying that mixtures are also applied.

[0016]

[Table 1]

Based on the above, a comparative experiment between the foam using the conventional activator and the foam using the alkyl glucoside according to the present invention will be described below. The active agents provided for the experiment are listed in Table 1. The conventional activator is a representative one selected from anion type cation type nonion type vinylon type polar type, and several kinds of alkyl glucosides according to the present invention are adopted. The concentration in the stock solution shown in the experimental data is based on the calculation as the pure content of the indicated components described in the catalog.

In the experiment, liquefied petroleum gas (deodorant for aerosol 4.4 kg /
10 g of (cm ² G) is filled in a test pressure bottle, shaken well, and spouted at 20 ° C. In a glass tube whose lower end is closed with a mesh net, collect the bubbles that have spouted and leave it. Depending on the bubbles, there are those that instantly become bubbles when ejected, and those that take 1-2 minutes to become solid bubbles,
When the glass tube is erected and left standing, the bubbles gradually become coarser and progress in the direction of disappearance. At this time, the undiluted solution forming the foam film is separated and discharged from the lower end. For 3 cases, the volume of the foam and the amount of the discharged liquid are observed every hour and shown in <Fig. 1>. The foam of the undiluted solution using the well-known general activator Dechton K is the most liable to break and the foam height is higher. Gradually decreases from about 5 minutes, and almost no residue remains after 60 minutes. Nikkor BL21 does not change for about 10 minutes, but disappears after 60 minutes. On the other hand, in the case of the monta knob 68 of the present invention, there is almost no change. Looking at the amount of drained liquid, it can be seen that it is significantly different. Although the bubbles are clogged, the specific gravity of the bubbles can be calculated by weighing the lath cylinder. Read (2) Drainage volume (10-minute value) as above. Separately, (3) measure the viscosity of the foam with a rotational viscometer,
These three points will be recorded in the following data as the characteristics of the foam that can be expressed numerically.

<Table 1> lists the characteristics of the foam produced by the undiluted solution containing the six types of activators (1) to (Fig. 2) and (Fig. 3), and the four types to (Fig. 4) and (Fig. 5). To raise. In the above experiment, it can be seen that the bubbles of the stock solution containing the Monta knob 68 are distinctly different from the bubbles of the stock solutions of the other active agents.

First, let us compare the specific gravities of bubbles.
In the conventional aerosol type foam, it is common knowledge that the specific gravity is about 0.03 to 0.08. That is, the higher the degree of perfection of foaming, the lighter it becomes. For example, the one that does not break for a long time like shaving foam is 0.03 to 0.05. Is large, and is, for example, 0.04 to 0.07 for hair setting mousses and 0.05 to 0.08 for cleansing mousses. If it is 0.08 or more, the tendency of sudge appears, and it is 0.
The use was limited except for special ones such as 1 to 0.12, and when it was 0.12 or more, the form of bubbles was not formed. Conventional bubbles naturally follow the path of destruction and disappearance when left unattended, and when measured by the drainage rate (value for 10 minutes), they showed at least about 10%. The foam viscosity was usually about 3000 cp, and even a thick foam such as shaving did not exceed 6000.

However, in the foam using the alkyl glucoside, as shown in FIG. 4, the foam specific gravity of the Monta knob 68 shows a very high value of 0.09 to 0.2. As shown in <Fig. 5>, the drainage rate is low, and the viscosity is about twice as high, so that the foam has extremely high stability, which breaks the above-mentioned common sense. I saw a great change leading to.

It is considered that the characteristic of this Monta knob 68 is that its substance is a mixture of cetostearyl glucoside and cetostearyl alcohol, and a combination of alkyl glucoside and higher aliphatic alcohol is combined. It was discovered that it is one that produces a particularly high degree of foam. Even in general aerosol type foams, it is already well known that the foam is hardened by adding a higher alcohol such as cetanol to the stock solution, but even in that case, the super stable foam as in the present invention was not produced.

[0023]

[Table 2]

<Table 2> is "Aura Mix NS10".
[Dodecyl polyglucoside (n = 1 to 3, R is C ₁₀ to
C ₁₄ mixture] and various higher alcohols, and the properties of the foam were observed. Fig. 6 shows plantacrene 2000 [n = 1.4, R = C _{8 to} C].
₁₆ ], Plantacrene 1200 [n = 1.4, R = C
In _{12 -C 16]} and three combinations of higher alcohols, in which the amount of the higher alcohol was seen the effect on the properties of the foam. From these, the following conclusions are drawn.

(A) In order to stabilize the foam, the blending of a higher alcohol which is solid at room temperature is effective. Liquid higher alcohols, on the contrary, have the effect of making the foam soft and smooth, so that the foam is not oily and has a smooth and improved feeling. Therefore, it is treated as included in a general oil agent. (B) The blending amount of the higher alcohol should be determined from the entanglement between the quality and the amount of the active agent, and the excessive blending acts to break the foam and the upper limit is about half of the alkyl glucoside. . (C) The effect becomes more remarkable as the C number of the higher alcohol increases, but the applicable range becomes narrower. Therefore, myristyl alcohol, cetyl alcohol, and stearyl alcohol are optimal from the viewpoint of their balance, and these are mixed and used. It is safer to do. (D) Therefore, depending on the kind of the alkyl glucoside, a stock solution having an amount of 0.02 to 8 w% and a normal temperature solid higher alcohol content of 0.01 to 4 w% is used in the present invention. That is why.

As described in detail with reference to the above data, if this is organized and pointed out, the product of the present invention has the following characteristics as compared with the conventional product. A) With the same amount of stock solution, the specific gravity and viscosity are almost 2 times that of conventional products.
Make double bubbles. B) The bubbles that have been ejected are extremely stable. C) Feeling: The foams using the conventional activators have a slightly different characteristic, but the appearance of the foams of the present invention is not so large. Has fine and uniform grains and maintains a moist and light feel, and the difference in texture is obvious.

From the matters described below, it will be understood that the product of the present invention has a surprising improvement. D) Effect of other additives: When a foam is intended to be a commercial product, various components are added depending on its purpose, but other chemicals are added as a general property of foam. And, it often has a negative effect on foam formation. For this reason,
In the prior art, the quality and amount of the additive had to be limited, but the product of the present invention can largely avoid this effect.

As a specific example, an experiment in which methylpolysiloxane is added to Table 3 will be described. Silicone has a wide range of uses as a lubricant and brightener,
On the other hand, it is a strong defoaming agent, and even in the case of an aerosol type foam, its foaming property was poor and it could not be used because of its defoaming action. However, it has been proved that the stock solution of the present invention can form bubbles with a low drainage rate even at 2% and extend the limit to 4%.

[0029]

[Table 3]

Thus, the additives may be other surfactants, thickeners, sizing agents, solvents, powders, lubricants, wetting agents, if necessary.
It is possible to add acid alkalis, ion sequestering agents, preservatives, coloring agents, fragrances, etc., and active ingredients. Explaining the total number of these is enormous, so representative examples of experiments <
Listed in Table 4>, other items are treated as equivalents.

[0031]

[Table 4]

Other conventionally used surfactants can be used in combination, and may be added for the purpose of enhancing emulsifying power, increasing solubilization, improving chargeability and wettability.
In this case, it is of course possible to predict that the properties of the foam will be changed, and examples thereof are listed in Table 5. In addition, although the pH of the stock solution after preparation was entered in the same table, it has been proved that the alkyl glucoside has no problem in a wide liquidity range of about pH 3 to 11.

E) Solvent (organic solvent compatible with water): In general, bubbles tend to disappear by the organic solvent. However, there is another report of the present inventor that, when ethanol is added as a known activator, blending of several% makes foaming smooth instead, but that also does not generate foam at a concentration of 25% or more. . However, in the present invention, a surprising new fact has been found.

FIG. 7 illustrates the experimental results by exemplifying a) acetone, b) ethanol, c) propylene glycol and c) N-methylpyrrolidone as organic solvents compatible with water. From this result, 30% by weight of acetone is the limit at which no foaming occurs. In the case of ethanol, interesting results are shown, and although the foaming property gradually decreases to 30w% as well, a bubble with another feeling, which is liquified when crushed with fingers with a very light feeling, is ethanol 45- Stable formation occurs between 65% by weight, and bubbles cannot be formed when it exceeds about 75% by weight. In the case of propylene glycol and N-methylpyrrolidone, this also shows an unusual characteristic, and a foam having a high viscosity is produced with an increase in the addition amount, and particularly in the case of propylene glycol, a highly viscous foam having a viscosity of 20000 cp or more can be produced. Foaming is not possible without water at all, but foaming is possible if only a small amount of 2-3 w% (that is, 97-98 w% of organic solvent) is present. This suggests the possibility of foaming with an organic solvent, and a compounded foam of a conventionally water-insoluble component (eg resin) can be expected. As shown in Fig. 7, the fact that two peaks are observed depending on the concentration is exactly the O / W, w of the emulsion.
It is a place of academic interest due to the appearance of the / O system.

F) Compounding amount of LPG as foaming gas (propellant): As described above, in the conventional aerosol type foam, 10 to w parts of the propellant is applied to 100 w parts of the stock solution. It was common sense. That is, if it is 6 w parts or less, it does not become bubbles, and if it is 12 w parts or more, single large bubbles are mixed and the entire foam lump becomes coarse, and if it is 16 w parts or more, it no longer becomes bubbles. This relationship will be described in the experiment of FIG. In the conventional stock solution of stearyltrimethylammonium chloride 1%, the measured value of the specific gravity of the foam shows that the dispersion in the case of 10 w part blending (marked with ▲) is 0.032 to 0.051. The value of the present invention (●) at the same position is 0.147 to
Since it is between 0.156, it may be relatively even. Moreover, in the case of the present invention, the ratio of the propellant to the undiluted solution was 4w part to 55w part or more, which means that the possible range of foaming was greatly expanded, and as can be seen from the drainage rate, this The foam is extremely stable.

The foam with a large amount of LPG (16w to 55w) is a new type that greatly differs from the conventional product in terms of texture. The foam particles are relatively large and feel light and dry. It's a bubble. And because of the heavy use of propellant,
If the valve button is properly selected, it can be applied to so-called "mist &foam" in which mist or water gun-like injection is performed and foam is generated on the surface hit by the injection object. Conventionally, this type was possible only when used in combination with DME, and therefore the foam was likely to collapse, but the product of the present invention was also able to maintain a stable foam state for a long time. Therefore, specifically,
Leads to applications such as thick film paints.

G) Using dimethyl ether as a foaming gas (propellant): DME is useful as an aerosol (mist type) because it has a property of being highly miscible with water and dissolving other organic substances. It is a propellant. However, since it has a defoaming action, it is rarely used for foam products, and even in mist & foam, 30% LPG
It was just to hit the mixture with. However, in the product of the present invention, even if the foaming gas was filled with DME, foaming was possible.

[0038]

[Table 6] Table 6 shows that the LPG: DME mixture at each stage was used as a propellant, and the stock solution was filled with a) a) Monta Nob 68 of the present invention, and b) known POE lauryl ether and stearyl trimethyl ammonium chloride solutions. This is what I saw the spray bubbles. As a result, in the known conventional product, a good quality foam is impossible with a mixed propellant having a DME of 60 or less, whereas in the case of the present invention, the foamability of the foam gradually declines, but a decent foam can be produced even with DME 100%. It was This implies the advantage that the active ingredient soluble in organic solvent can be distributed in the product foam.

The liquefied gas applicable as a foaming gas includes
Apart from the discussion of economic efficiency and versatility, nitrous oxide and non-specific CFCs (134a, 123, 141, etc.) can be mentioned.

H) Using Carbon Dioxide (Other Compressed Gas) as Foaming Gas: Most foam products currently on the market
Although LPG is used as a propellant, the use of CFCs was restricted by the Montreal regulations where CFCs 11 and 12 were once the mainstream. As a result, aerosol foam products used in places where fires are strictly prohibited will be completely destroyed. It has arrived. However, there are still many demands for products that are strictly prohibited to use fire, and therefore non-combustible gas (for example, CO
₂ ) was examined, but no foam was generated. However, according to the present invention, an aerosol type foam product using carbon dioxide gas as a foaming gas (propellant) was completed.

[0041]

[Table 7]

<Table 7> describes the foam products filled with carbon dioxide. In this experiment, the stock solution with different concentration of Monta Nob 68 as the activator was filled up to half the volume of the pressure canister, the mountain cup was caulked under vacuum, and CO ₂ was injected under pressure until equilibrating to 7.5 kg / G at room temperature. As a product. As for the foam state, the higher the activator, the more stable the foam is made, but if the activator is 0.5% or more, a satisfactory foam form that can be used as a commercial product is created. From the weight measurement,
The CO ₂ loading is calculated to be 1.45 g on average / 100 g stock solution.

Carbon dioxide dissolves in water under pressure, and is it possible that the above numerical values are higher than theoretically calculated values from the Ostwald index due to the action of the activator? The use of other compressed gases (nitrogen, hydrogen, argon, air, etc.) instead is disadvantageous because of its low solubility, but it does not make a foam. In such a case, too, the compressed gas leaks or malfunctions, causing a rapid pressure drop. Therefore, a small amount of liquefied gas may be used together as a countermeasure. The addition of LPG would be inconsistent as these compressed gas foams would apply as a means to handling fire hazards. However, even with LPG, when the amount is 4 w or less, even if the generated foam is directly exposed to the flame, it does not ignite. Four
Although it does not become a foam in the w part or less, it is possible to provide a non-combustible aerosol type foam product by applying a compressed gas to supplement the pressure.

Although the technical basis of the present invention has been described above, there are other agents added to the product of the present invention.

【Example】

Example [I] -Claim 1 This example is a polishing agent used in automobile / household products. [1] gives a bright gloss and [2] gives a soft gloss. The foam quality is slightly soft and has a fine texture.

Embodiment [II] -Claim 1 This embodiment relates to a shaving foam.
Conventionally, this aerosol type includes a) using potassium soap and b) using lauryl sulfate. The former was alkaline, and when used in combination with a steaming towel, the hair became soft and easy to shave with a razor. However, when an electric shaver is used, the latter of the slightly acidic side is said to be preferable because it hardens the hair and makes it easier to bite. In this example, the liquidity may be changed freely, and it is devised so that it is comfortable to shave. The foam has a heavy feel, a dense creamy texture, is easy to stick to the skin, and does not sag.

Example [III] -Claim 2 This example is a cosmetic for UV protection. For this purpose, the SPF value is increased by the combination of an ultraviolet absorber such as oxobenzone and an ultraviolet shielding agent of a fine particle pigment. However, in the conventional aerosol foam type, when these agents are mixed, the foam is destroyed. , I couldn't create the foam quality that satisfied the dignity of cosmetics. The foam of the product of this example is a beautiful foam lump, in which the foam particles are well-aligned, and the skin has good moistness, and can be applied evenly to the skin.

Example [IV] ... Claim 2 This example is an example of a hair setting mousse. Most of the resins used here are neutralized with alkali and mixed as water-soluble, but completely neutralized (pH becomes 8 or more).
Since the fixing after applying hair is weak and sticky may appear, the neutralization degree of alcohol-dissolved mist products is around 60% (pH
= 6.5). In mousse, the degree of neutralization is set to about 80% (pH = 7.4), but even when LPG is filled, the equilibrium may be broken and resin precipitation may be observed. Therefore, it is desired to use DME as the propellant to improve the solubility, but then there was a dilemma that bubbles could not be formed. In this example, DME is used as the foaming gas, and even if the degree of neutralization is about 70%, no resin precipitation is observed, and the purpose of enhancing the setting force and suppressing flaking is almost achieved.

Example [V] -Claim 3 This example relates to a so-called "thick film paint" having a thick coating film after construction. Conventionally, it is applied by brush painting using a lot of fillers or by a blowing method in which air is mixed in with a compressor. The aerosol type was once made as a prototype, but it has not been completed. According to the present invention, since the foam is stable for 5 to 6 hours, a resin that solidifies during this period may be selected. Also, in this example, the content of the propellant is large, and the content spouts in the form of water filaments and foams on the coating surface that it hits, so construction is easy and it is possible to apply even beyond reach. There is an advantage that can be done.

Embodiment [VI] ... Claim 3 This embodiment is a screen door cleaner. Since the screen door is located outdoors and has a fine mesh, it is easily dusty and difficult to clean. With the aerosol, the mist type allows the drops to pass through, while with the foam type, the work of applying it to the entire screen is involved. In this respect, the mist & form type is convenient. Naturally, a button having an injection port that meets the purpose of this example is custom-made by a specialist.

Example [VII] -Claim 4 This example is a prescription example of a bath cleaner. In a Japanese-style reheating type bath, the bath water is circulated and heated by passing it through a heater coil, which causes dust to adhere to the inner wall of the coil, which reduces heat efficiency and is unsanitary. As usual, there is a method of injecting aerosol foam into this cleaning method. In the past, because CFC was used as the propellant, special consideration was not required for fire, but after changing to LPG, it is troublesome with precautions such as prohibiting its use in structured baths near the crater. became. In this example, a small amount of LP
G is included, but the bubbles do not ignite and can be used with confidence.

Embodiment [VIII] Claim 4 This embodiment relates to a cleaner for equipment such as aircraft. In these places, the maximum consideration is given to the fire, and the fire alarm is also equipped with a heat detection type, a smoke detection type, and a combustible gas detection type. It is built so that actions can be taken automatically. For this reason, the cleaner in this place
The LPG cannot be used, and the foam type is the best for cleaning equipment that is covered with machine oil and dust.

Example [IX] -Claim 5 This example relates to a detergent for food. Since recently imported raw vegetables and fruits are concerned about pesticides, preservatives, parasites, it is better to wash and remove them before use. Currently, a dishwashing agent containing dodecylbenzene sulfonic acid, etc. (according to the Household Goods Labeling Control Act) is used as a substitute, but the effect of the residual activator on the human body at this time has not been clarified. Previously, the present inventor applied for a food detergent with sucrose fatty acid monoester and alcohol, which is also permitted as a food additive, but by adding alkyl glucoside to this, the washing effect is further synergistically improved. I just found out what to do. All of the raw materials used in this product are safe to eat, and alcohol also serves the purpose of bactericidal action.

Embodiment [X] ... Claim 5 This embodiment relates to a cleaner for an automobile engine trunk. The engine room is very polluted with dust and soot, which can lead to failure to dissipate heat and short circuit of electrical wiring. It doesn't completely go through. Strong solvent type for oil removal should not be used as it embrittles the insulation of electrical wiring and it is difficult to remove dirt that has been mixed with oil and stuck to it. Therefore,
The solvent was appropriately emulsified, and a foam type product of the present invention was introduced. Although it is generally said that the presence of a solvent does not result in foaming, it was common knowledge that foaming was made possible by applying the present invention by using a solvent such as N-methylpyrrolidone that is miscible with both oil and water. Of.
The foam quality can be changed in any way by considering the ratio of the oily solvent such as kerosene, the water-miscible solvent and the water.

INDUSTRIAL APPLICABILITY The present invention relates to an aerosol-type aome product, and overcomes the current situation where the product group to which the aerosol product is made is rudely used. A) The foam according to the present invention exhibits an unprecedented special texture. B) It is possible to make bubbles having a specific gravity and viscosity several times higher than those of conventional foams. C) Bubbles are very stable and can be made that do not collapse for hours. (Of course, the same as the conventional product is also possible by adjusting the composition.) D) Other additives [eg silicone: In the past, it worked for defoaming, the amount added was limited] Becomes E) When an organic solvent compatible with water is added, a very characteristic behavior is exhibited. For example, in the case of propylene glycol, 98
It is possible to foam up to a concentration of 2% (water 2%), and the foam has a high viscosity of tens of thousands centipoise. F) When LPG is used as the propellant (foaming gas), it is possible to foam by blending 4 to 55 w parts of the stock solution. H) When the LPG is frequently used in an amount of 16 to 55 w, a product of the type in which the ejected substance comes out in the form of mist or water gun and foams on the coated surface can be produced. I) The compounding of DME with the propellant (foaming gas) is limited in its amount due to the defoaming action, but it can be widely used in the present invention. J) A non-combustible foam can be produced by using a compressed gas such as carbon dioxide as a propellant (foaming gas).
