Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid composition for producing a foam-containing mass, and the foam-containing mass as used in the present invention is mainly used in the cosmetics field (including quasi-drugs referred to in the Pharmaceutical Affairs Law). Included) refers to what is currently referred to as a form or mousse. Therefore, when the liquid composition of the present invention is put into a pump type foamer to operate, a foam-containing lump can be formed, and it is mixed with a liquefied gas, and in the form of an aerosol product put in a pressure-resistant can, cosmetics and even household products are used. The field of application of the present invention extends to the range of goods and foods.

[0002]

2. Description of the Related Art A bubble-containing lump (hereinafter, also referred to as a foam) is capable of effectively using a small amount of a chemical liquid because of its physical properties. # Does not sag when applying. # The unique texture of the chemical is utilized. # It is applied to various fields by taking advantage of the special usage that covers the coated surface for a long time. One of the methods of making foam is to vigorously stir a liquid composition that makes the foam (hereinafter also referred to as the undiluted liquid solution or simply undiluted solution) and mix air into it. Yes, and recently, a pump-type former with a container has been sold. Also,
Liquefied petroleum gas (LPG), dimethyl ether (DM
E), chlorofluorocarbons, nitrous oxide (N ₂ O), and other liquefied gases (some of which may be partially mixed with compressed gas such as carbon dioxide gas and nitrogen gas) and the stock solution are press-fitted into a pressure vessel to form a valve. A so-called aerosol type product in which the content forms a foam when the button is pressed is a general product because it is easy to use and has a good foam quality.

In order for the undiluted solution to produce foam, the incorporation of a foaming agent is an essential condition, most of which are similar to surfactants. However, it does not mean that the surfactant is immediately compatible with the foaming agent. Soap (alkaline salt of higher fatty acid) has been the most widely used typical foaming agent from the old days of LeBlanc, it has strong alkali, is not compatible with hard water, and does not foam well in a small amount. Although it has been pointed out that there is a drawback, it has the advantages of good defoaming, a refreshing feeling after use, etc., and it has recently been reviewed in reverse because it is close to a natural type. With the development of the chemical industry, there have been provided products with superior surface active effects, those with different ionic properties, those that do not irritate the skin of the human body, and those that exhibit their respective characteristics. As a result, bubbles can be made to have various characteristics and can be made to have various characteristics. Currently, most commercial products are based on the blending of these classified raw materials. On the other hand, regarding natural foaming substances, it is recorded that the bark and fruits of psychedelic and mukuroji were crushed and used for washing. This foaming substance is called saponin. In addition, pine resin "rosin" (main component: triterpetide called abetiic acid) has been used to help foam the soap. In nature, proteins, pectins, polysaccharides, and phospholipids have some foaming substances. But these natural systems. Foaming agents are too classic to be used long before they have been put on the market, and there are no known references to use them in stock solutions of aerosols.

In our daily lives, surfactants are becoming chemical substances lacking, but on the other hand, there is no remorse for their use. In other words, apart from soap, there is a problem that some synthetic experts oppose from the viewpoint that other synthetic surfactants destroy the global environment. In other words, it is clear that the pollution of the active agent after use in the river will affect the aquatic plants and animals, and it will leap when the change spreads to the whole ecosphere of the earth, and the river water will be used for drinking. It is said that this is a harmful cause to the human body. Therefore, it is necessary to reduce the amount of surfactants used and to develop a sex agent that easily decomposes spontaneously. By the way, there are commercial products that claim the use of mild, naturally gentle activators, but these are semi-synthetic activators that incorporate, for example, natural coconut oil fatty acid or tallow fatty acid in the molecule of the activator used, It is essentially different from the natural active agent as referred to in the present invention.

[0005]

As described above, foam products are reasonably convenient and widely used, but it is accused that the surfactants contained therein are one of the causes of environmental damage. Based on a certain reality, it is desirable to substitute an activator that easily decomposes spontaneously. Soaps fall into this category, but their pH is high (10.2.
10.5) Neutralization is required before flowing into a river, and it is known that the decomposition purification value differs depending on the type of fatty acid used here, and that naturally derived products undergo microbial decomposition.

[0006] In the natural world, if a substance produced by animals and plants is present, microorganisms, fungi, and enzymes that decompose it are digested in nature, but artificial compounds are difficult to decompose. , This often causes global pollution. From this perspective,
The present inventor has tried to formulate a "liquid composition for forming a foam-containing lump" by adopting a naturally-derived substance as much as possible, and then the surfactant must also be of a natural type. However, the activity of natural activators is generally lower than that of synthetic activators, which is a subject that requires technical studies for making foams.

[0008]

[Means for Solving the Problems] As a means for solving the problems, the present inventor has conducted a number of experiments, and the result reached is “0.08 to 10 wt% of saponin-containing plant extract and / or saponin-containing plant extract as a foaming agent. And, if necessary, as a foam quality improver, surfactant, lubricant, thickener, paste, oil, solvent, powder, acid alkali, pH adjuster, ion sequestering agent, preservative, colorant, fragrance. , One or more of
One or two or more active ingredients corresponding to the purpose and the balance of 100% by weight of water, and the pH of the solution is 3.2 to 1
It is a liquid composition for producing a bubble-containing lump, characterized in that it is 0.2. Thus, as a kind of a foam quality improving agent, “a> 0.01 higher aliphatic alcohol having 8 or more carbon atoms” is used. ~
5 wt%, b> 0.0 higher aliphatic fatty acid having 8 or more carbon atoms
It is pointed out that "adding 1 to 5 wt%" brings about a special effect.

Before specifically describing this content, "foam"
In the present specification, although it is widely interpreted to be comprehensive, in the present specification, when a compounded liquid composition confines a gas to form a bubble, an aggregate of bubbles is referred to as a “foam-containing mass (form). In addition, when the bubbles have a large particle size and are single bubbles such as soap bubbles, the liquid encloses the gas and forms a so-called "foam film", but the particle size is small. Moreover, the foam film was not clear in the aggregated foam-containing lumps, and it seemed that the bubbles were surrounded by the liquid under the microscope. "Bubble" is a state in which the number of bubbles in the liquid is small and it floats alone.
This is called “sudge” when the amount of bubbles gradually increases and the liquidity is reduced just like the top bubbles of beer. "Foam" is a liquid that has a smaller proportion, loses fluidity, and has a viscosity that allows it to be scooped with the palm. Although xerogel, in which a solid surrounds a fine gas, is a kind of bubble, the definition of “bubble” in the present specification is as described above. Regarding the properties of foam, <specific gravity> Aerosol Sangyo Shimbun No. 735 “92.7.5”, <viscosity> 753
No. 93.1.15, <Antifoaming> No. 780, 93.
The present inventor has contributed to 10.15, <Particle size> No. 797, No. 94.4.15, and the details of the measuring method are described in the report.

Furthermore, regarding the form, the hardness, the stickiness,
Crumbling, adhesiveness, drainage, fineness of texture, uniformity of foam particles,
It is evaluated according to various criteria based on the judgment criteria such as the presence of large bubbles, smoothness, gloss, and odor. If the measurable numerical value is used to express the state of bubbles, specific gravity is the simplest method. In a general form, 0.03 is normal in shaving foam, and as the specific gravity becomes higher than that, it becomes coarse foam and it becomes easier to break the foam.
For example, in body soap foam, it ranks 0.05.
When it exceeds 0.1, a remarkable drainage phenomenon is observed, and when it is 0.2 or more, it becomes a sag, which has almost no use. Also, the foam film is light There is a method to estimate the relationship of grain size.

Foaming agent: Regarding "saponin array / or saponin-containing plant extract". Saponins are glycosides widely distributed in the plant kingdom, and there are two types of sapogenin structures, triterpenoids and steroids. Typical examples of the contained plant are saponsou, kizuta, succulent skin, quilla skin, ego, sycachi, soybean seeds, tea grain, dandelion rhizome, cod leaf, etc., and hamamelis powder, sucrose extract, tea seed are licensed items by cosmetic variety. Extract, Agets extract powder, are listed. Since it is soluble in hot alcohol and insoluble in many organic solvents, it is purified by such an extraction repeating operation. However, in this specification, the component amount is 0.08 to
10 wt% is not a pure product but is defined by the dry matter content of the saponin-containing extract. Specifically, the extract products manufactured and sold by [Maruzen Pharmaceutical Co., Ltd.] contain this level. This is because it is a component and the structure and type of saponin differ depending on the plant. For example, saponin contained in Sucrose (Sapindus Mukurossi) is called Sapindus saponin,
The sapogenin is hederagenin [Chemical Formula I] classified as β-amyrin type. Since it is an acidic saponin having -COOH in structure, it is almost alkaline in pH 7.2 or more and almost dissolved in water, and vigorous foaming is exhibited. (Solubility pH
4.4: 2.4%, pH 6.2: 3.8%, pH 7.
2:> 10%, measured value of the present inventor). In addition, various saponins are known, for example, a betulin type compound having a pentagonal E ring in the chemical formula I, a steroid saponin having a polycyclic ring connected to the E ring, and the like.

[0012]

[Chemical formula 1]

This product is derived from natural products,
Bacterial degradation tests have shown several grades of degradation compared to other currently popular surfactants. However, the foaming ability is judged to be slightly inferior as shown in the experimental results in Table 1. 20m undiluted solution for foaming test
1 is placed in a 100 ml graduated cylinder, stoppered, shaken 20 times, and the amount of foam produced is read. With respect to the active agent, a solution having a concentration of each step is prepared on the basis of the dry solid content, and a test is carried out by the same operation to determine the foaming ability. Table 1 shows a comparison with other typical active agents. From this result, it is recognized that the foaming ability of savonin is inferior by an order of magnitude, and particularly, it is low on the acidic side (pH <3.2). This inferior foaming ability is a very disadvantageous condition for producing the foamed mass which is the object of the present invention.

[0014]

[Table-1]

To solve this problem, the means taken by the present inventor is to increase the content of a) a foaming agent (savonin). b> The pH of the liquid is 3.2 or more, and it is made as alkaline as possible. c〉
In addition, (a) higher aliphatic alcohol, which should also be called a foaming aid, and (b) higher aliphatic fatty acid are added. However, these measures may not always be appropriate. For example, it is common knowledge regarding foaming that a> a large amount of a foaming agent is blended, but it is sticky at the time of applying the foam and is disadvantageous in cost. Therefore, at least 0.5 wt% for foaming, and 10 wt% for foaming.
It is the following. Regarding b> pH, if it is 7.2 or more, it is soluble in saponin, but if it is too high, the skin irritation becomes strong, so the maximum was kept at 10.2. . c) Foaming aids: The additions of a> and b> are dramatically improved, especially at low foaming agent concentrations,
It has become possible to extend the minimum amount of foaming agent to a width of 0.08 wt%. The effective addition amount of the foaming auxiliary agent is related to the compounding amount of the foaming agent and should be appropriately determined. An improvement effect is recognized from a minimum of 0.01 wt%,
If it is 5 wt% or more, it is not so good, and on the contrary, it may have an adverse effect. Examples of such foaming aids have been found in conventional soaps and shampoos, but this is the first attempt to combine the foaming auxiliary with the natural foaming agent of the present invention.

The definition of an aliphatic higher alcohol is an organic substance having a chain bond of 8 or more carbon atoms in the molecule and having an OH group, and octanol, decanol, lauryl alcohol, myristyl alcohol, stearyl alcohol, cetanol, behenyl alcohol, Cetostearyl alcohol, oleyl alcohol, lanolin alcohol, hydrogenated lanolin alcohol, octyldodecanol,
Specific examples thereof include hexyldecanol, jojoba alcohol, refined coconut oil fatty alcohol, and isostearyl alcohol.

The definition of an aliphatic higher fatty acid is an organic substance having a chain bond having 8 or more carbon atoms in the molecule and having a COOH group, and is capric acid, caprylic acid, lauric acid, myristic acid, myristolenic acid, pentadecanoic acid. , Palmitic acid, palmitoleic acid, margaric acid, stearic acid, oleic acid, linoleic acid, linolenic acid, arachidic acid, cadrenic acid, behenic acid, coconut oil fatty acid, tallow fatty acid, hardened beef fatty acid, whale oil fatty acid, isostearic acid,
Etc. are mentioned as a specific example.

Since the above-mentioned aliphatic higher alcohol and / or aliphatic higher fatty acid have different physical properties,
The foam to which it is added naturally has a different character especially in the texture. For example, when oleyl alcohol is added, the foam is smooth and adheres well to the skin, and when cetanol is added, the foam is slightly hard and has a pudding, elastic and light feel. Thus, it is selectively compounded together with other foam quality improving agents in order to make the foam quality preferable for each application. It should be noted that higher fatty acids are known to act as soaps when they are highly alkaline, but in the case of the present invention, they are within the low pH range that soaps do not constitute.

For the above description, the experimental data of the present inventor will be described. Figure 1 shows saponin (Merck)
Solution with a concentration of 0.02 to 15 wt% (pH 4.0 to 4.5
40 g of undiluted solution and propellant [LPG (4 k
g / -cm ² G)] 4 g and the specific gravity of the foam ejected from the aerosol type. As mentioned above, when the specific gravity exceeds 0.2, it becomes sagging, and practically when drawn with 0.1, saponin single blend [○
0.5% by weight for the [mark, solid line], while 0.07% for lauryl alcohol 0.2% additional formulation [△ mark, disconnection]
It can be seen that the lower limit range is widened to 0.05 in the case of 0.2% additional addition of lauric acid [□, chain line].

Next, the relationship of pH will be described with reference to FIG. Saponin (total) concentration of 0.5 wt% [●, solid line],
To this, 0.2% of cetanol [marked with a broken line] and 0.2% myristic acid [marked with a black square marked with a dotted line] were added and the pH was added.
The liquid with the changed value was used as the undiluted solution.
The specific gravity of the aerosol type foam filled with 4 g of PG (4 kg / cm ² G)] is shown in the figure. From this figure, pH
This is the point where the foam specific gravity changes abruptly with 3.2 as the limit.
It is observed that the higher the H, the lower the specific gravity of the foam. However, if the pH is too high, it deteriorates and there is a practical problem. Therefore, in this patent, it is limited to 10.2 or less.

The effect of the addition of the aliphatic higher alcohol or the aliphatic higher fatty acid is clear in the above figure, and the relationship of the amount will be explained in FIG. Saponin (all above)
0.1 wt%, ethanol 10 wt%, and oleyl alcohol [▲ mark, broken line] or oleic acid [▲ black square mark, dotted line] at each concentration to make pH = 5 ± 0.1, and 40 g of this stock solution In contrast, as a propellant [LPG
(4.4 kg / cm ² G) 10 g + DME 22 g] was measured, and the specific gravity of the ejected foam of the aerosol was measured. From this result, the effect is recognized when the added amount is 0.01 wt%,
It shows that the deterioration is rather caused when t% or more. By the way, this formulation is commonly called "mist &foam", and it forms bubbles when it is sprayed and adheres to the coated surface.

[0027]

【Example】

Example [1] This example is an example of a screen cleaner liquid. You may use this formulation liquid by putting it in a pump former to make foam,
Of course, it can be used as an undiluted solution for aerosol. Although the screen door tends to get dirty, the detergent solution flows without sticking to the net, and the aerosol fog passes through the mesh.
However, the foam has the advantage that it stays on the mesh yarn and the cleaning action time of the drug can be kept long. In addition, since the screen doors are usually washed outdoors, the wash water directly flows into the river like rainwater and causes pollution, so care must be taken regarding the activator.

Embodiment [2] This embodiment is an example of body soap. Soap means soap, but the conventional fatty acid alkali has a high pH of more than 10, and a strong skin contact phenomenon was observed in infants and women with weak skin. For this reason, body soaps using neutral soap have appeared, but there are many opinions that this synthetic detergent inevitably leaves a slimy feeling even after use. By the way, body soap is popular because there is almost unlimited use of wash water in hotels and hot springs (or luxury apartments). However, these are mere fluids filled with a pot, and the foam type is not widely used. By the way, the following formulation solution of the present invention is a stock solution for diluting it about 5 times into a foam pump at the time of use and coating the resulting foam on a body for use. It has a refreshing feel and does not have rough skin.

Example [3] The present invention is an example of an aerosol type shaving foam. It is desired that the shaving foam has a relatively fine texture, is finely textured, has no drip, does not drip, and has good adhesion to the skin. Conventional materials generally have to have a high pH in order to satisfy this condition because of the relationship with the raw materials used. But the physiological p of healthy skin
H is around 4, and it is not preferable to set the pH to 9 or higher because "shavering" occurs. This product satisfied the above-mentioned conditions and, as a result of a practical test, it was well-received because of good sharpness. Prescription (wt%) I. Undiluted solution II. A shaving foam aerosol product according to the present invention was prepared by filling 180 g of the above stock solution and 20 g of liquefied petroleum gas (4.4 kg / cm ² ) as a propellant into a pressure resistant tin can for an aerosol, attaching a valve, a button and a cap. Manufactured.

Embodiment [4] This embodiment is a cleansing mousse. To remove makeup, water / oil pigments such as foundation, lipstick, and eye shadow, as well as sweat and dust had to be removed. For this reason, conventionally, many have used strong surfactants and blended scrubbing. This removes the moisturization of the facial skin and causes rough skin. The products of the present invention listed below are slightly acidic and do not strongly solubilize fats and oils, so that they do not forcefully remove the fat content of the skin. Also, the scrub is in a form coated with a semi-micro gel of saponin, which does not scrape the skin. I. Undiluted solution II. 120 g of the above stock solution and 14 g of liquefied petroleum gas (4.4 kg / cm ² G) as a propellant were filled in a pressure resistant aluminum can for an aerosol, and a valve, a button and a cap were attached,
A cleansing foam aerosol product according to the invention was produced.

Example [5] This example is an aerosol mousse for setting hair. There are hard type and soft type for hair setting, but it is possible by changing the type of sizing agent (resin) referring to the following prescription. This product has an extremely firm setting force with no flaking and gloss. It should be noted that, during the formulation ,,,,, contribute to foam formation and foam quality, and have the effects of strengthening the setting force and repairing the hair quality. I. Undiluted solution II. 100 g of the above stock solution, 24 g of liquefied petroleum gas (5 kg / cm ² G) as propellant, and dimethyl ether 6
g was filled in a pressure-resistant aluminum can for an aerosol, and a valve, a button, and a cap were attached to produce an aerosol product of a hair setting foam according to the present invention. When the button of the mist specification type is adopted, it becomes a so-called mist & foam type, which means that when sprayed toward the head, the undiluted solution attached to the hair becomes the foam. Therefore, if this is comb-through, the color is rolled and the hair is dried, the curl of the desired hairstyle is set. If you wash your hair with shampoo hot water,
Easy to wash off without damaging your hair.

[0032]

The present invention has been researched and completed in response to a request from a naturalist group who wants to use a natural product as much as possible. However, with the thought that artificial development will destroy the environment, change the global ecosystem, and adversely affect human life, we try to prevent chemicals from dripping as much as possible. It is one of the bad chemicals.
Therefore, in the present invention, the saponin extracted from the natural world is used as the surfactant, and other compounded substances are made as natural as possible. Although it can be understood that the self-cleaning decomposition is promoted by using the natural system as described above, the performance is inevitably inferior to that of the existing product because the raw materials are limited. In that sense, the product of the present invention is by no means inferior, and it is possible to evaluate the performance of the surface which is rather contradictory.
