Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a chemical liquid applied to a pump type former, and when it is put in a container of a pump type former and ejected, the ejected substance is foamy. Household goods, industrial goods, automobile goods, gardening goods, human body goods,
There are application fields in various fields such as sports equipment.

[0002]

2. Description of the Related Art Conventionally, when making foam, it has been obtained by manually vigorously stirring the liquid as is found in the hairdressing industry. Although there has been some progress in converting this to electric power, there is not much reform. Nowadays, the aerosol type is widely used for the above household products because of its convenience when used.
Aerosol products have the convenience that they can be used with a mist type without pushing your hands by simply pressing a button, and that even a small amount of chemical liquid can be applied evenly and uniformly. However, in recent years, the problem of global environmental pollution of VOCs (volatile organic substances) has been taken up, and there is a social situation in which the consumption of liquefied petroleum gas, dimethyl ether and CFCs as propellants is suppressed.
Therefore, very recently, a few companies have been developing and providing mechanisms with a container that creates foam by a hand pump. This structural container is called a pump former.

[0003]

The pump type former has been recently commercialized, and little research has been conducted on a compatible chemical liquid. A mist type container mechanism using a hand pump has been commercialized as has been known as "mist spraying" for a long time, and the content drug can be diverted without any difference from the aerosol type. However, the "foam" type is assembled with a special container mechanism, and it is not the same as the aerosol type chemical solution. That is, in the case of an aerosol, the enclosed liquefied gas forms bubbles when vaporized in a chemical solution, and in a pump type former, it is a structure that finely mixes air, so the degree of pressurization The amount of gas is so small that it cannot be compared, and therefore the foaming condition is necessarily extremely bad.

[0004] Therefore, as a chemical solution for a pump type former, in order to make bubbles easy, in other words, a solution containing an increased amount of a surfactant compounded for foaming has been used. However, when this increase is inappropriate for some applications, for example, a dry shampoo for a human body product often has a sticky feeling, and a cleaner for a household product leaves stains. Therefore, an attempt was made to reduce the amount of the activator in the chemical solution, but the physical properties of the foam became poor, or finally the foam was not formed. Therefore, the subject of this invention is mix | blending an active agent with a small amount, and creating the chemical | medical solution for pump type | formers which produces | generates a foam with a good condition.

[0005]

[Means for Solving the Problems] As a means for solving the above problems, the present inventor conducted numerous experiments, and the conclusion reached was that "surfactant 0.01-1.0 wt% and ethanol 0.02- 30 wt% and, if necessary, as a foam modifier, a modifier, a thickener, a sizing agent, an oil agent, a solvent, a pH adjusting agent, an ion sequestering agent, a coloring agent, a fragrance, or one or more kinds thereof. And one or two or more active ingredients corresponding to the purpose, and the balance being 100 wt% with water, the evaporation residue at 105 ° C is 2.5 wt% or less. " The present invention is completed by filling the composition in a pump former.

[0006] Normally, the formulation of a foaming product is about 1% to 1% or more even in the case of an aerosol product, whereas the formulation of a foaming product is much less than that of a chemical used for a pump former having a poor foaming property. Therefore, it is intended to reduce the amount of the activator and to supplement the decrease in the foaming power which is naturally a problem at this time by adding ethanol. With regard to foam intensification, it has been conventionally accepted that higher alcohols such as cetyl alcohol having a high carbon number have such an action, but lower alcohols such as ethanol have an antifoaming property. Therefore, adding ethanol to a place where the concentration of the activator is low and where foaming is unlikely to occur is completely unthinkable.

Before specifically describing this content in detail, "foam"
In Japanese, it is understood that a wide range of substances are included, but in the present specification, when a drug solution confines a gas to form a bubble, the aggregate of the individual bubbles is referred to as a "foam (foam or mousse)". ". When the bubbles have a relatively large particle size, for example, in the case of a single bubble such as a soap bubble, the liquid encloses the gas and forms a so-called bubble film. Is not clear, and it seems that air bubbles are surrounded by the drug solution. In general, the state that bubbles can be seen alone and drift in the liquid is called a bubble.
It is said to be a sedge when the number of bubbles gradually increases and the ratio of the liquid decreases and the bubbles do not move. Foam seems to refer to a collection of foams without distinguishing individual foams, solid /
A gas bubble (xerogel) is also included, but the definition in the present specification is as described above.

Regarding the properties of foam, <specific gravity>: Aerosol Sangyo Shimbun No. 735 '92 .7.5, <viscosity>:
No. 753 '93 .1.15, <Defoaming property> No. 780
'93 .10.15, <particle size> No. 797, '94.
The present inventor has contributed to 4.15, and details of the measuring method and the like have been described in the report. Regarding the properties of foams, in the above report, the specific gravity of the foam is generally 0.03 to 0.
No. 05 is normal, and as the specific gravity becomes higher, it is a rough foam that is more likely to be broken. When it exceeds 0.1, a drainage phenomenon is observed, and when it is 0.2 or more, the foam breaks and becomes a sudge. Stated. It is also described that since the foam film has a function of refracting and reflecting light, the particle size relationship can be estimated by measuring its absorbance.

Now, the experimental results relating to the present invention will be described below. FIG. 1 shows the results of making solutions with different surfactant contents, jetting bubbles with a pump-type former, and measuring the specific gravity of the jetted substances. The figure shows the specific gravity of the bubbles on the vertical axis and the surfactant concentration (%) on the horizontal axis. In the figure, the points Δ / dashed line show the solution of the surfactant, and the points ○ / solid line show the measurement of the solution added with ethanol. It is a value. A: <Sodium dodecylbenzene sulfonate. The amount of ethanol added is 10 wt%> From this figure, it is shown that the ethanol-free one is lighter than the one with a high activator concentration, that is, stable, but 0.8 wt%
The effect of ethanol is remarkable on the low concentration side. Those without addition of ethanol had an activator concentration of 0.
On the other hand, when the content is 075% or less, foam cannot be produced (foaming limit concentration), while the foaming limit concentration in the case of adding ethanol is 0.025%.

B: <stearyltrimethylammonium chloride. The amount of ethanol added is 5 wt%> In this figure, the reversal point is 3%, and the specific gravity of the bubbles when ethanol is not added is uniformly 0.08, that is, it is watery and easily broken. ~ 0.0 when ethanol is added
It can be seen that it has decreased to 4 and increased stability. The foaming limit concentration is 0.07% when ethanol is not added, and 0.017% when ethanol is added.

C: <lauryl sulfate triethanolamine: polyoxyethylene (hereinafter abbreviated as POE) oleyl ether [HLB10.5]: cetanol = 5: 4:
One. Amount of ethanol added is 20 wt%> It has been reported that hard foam quality can be obtained by adding cetanol. In this figure, a remarkable improvement effect is recognized especially when ethanol is added. That is, the lowest specific gravity of foam without addition of ethanol is at a concentration of 3 to 4% of the activator, whereas with addition of ethanol, it is as low as 0.1%.
Furthermore, the feature that foaming is performed even with 0.01% of a surfactant is exhibited.

D: <coconut oil alkyl betaine: coconut oil fatty acid diethanolamide = 7.5: 2.5. Ethanol addition amount 2 wt%> This figure is an example of a mixed activator, but it is also preferable to add ethanol. The foaming limit point is 0.15% without addition of ethanol, and 0.07% with addition of ethanol.

Thus, the effect of ethanol is clear,
FIG. 2 shows the experimental results for determining the ethanol amount relationship. The activator was <Na dodecylbenzene sulfonate> 0.2%, and the specific gravity of the foam made with the chemical solution having the ethanol content of each concentration is shown. This result shows that the lowest ethanol concentration is 1
It is 0 wt%, and when it is 30 wt% or more, foaming is lacking. On the low compounding side, the difference from the case where 0.01 wt% is not added is clear. However, in terms of foam quality, a point of 0.02 wt% greatly changes.

From the viewpoint of the feel of bubbles, clean bubbles generally have a uniform particle size, and coarse bubbles often have large bubbles because the particle sizes are not uniform. The particle sizes of bubbles can be compared by measuring the absorbance using a colorimeter. At this time, there is a means for measuring the number of points and determining the variation to evaluate the quality of the bubbles. In FIG. 3, the absorbance of a foam layer having a thickness of 0.5 mm was measured at 10 locations, and the range of dispersion and the average value were shown. From this result, it is proved that the amount of alcohol is within the range of 0.02 to 30 wt% and the variation is small.

The blending amount of the surfactant is 0.01 to 1.0.
The reason for setting wt% is that the lower limit side is considered to be the limit with the result of forming foam even at that concentration as described above, and the upper limit side was agreed with the point that the specific gravity value, which is the characteristic of ethanol addition, is reversed. is there. Of course, there are many cases in which bubbles are formed even at higher concentrations and the good effect of adding ethanol appears. However, another feature of the product of the present invention is that it does not feel sticky after use,
The goal is to leave no stains. This point was judged based on the data collected by the monitor survey of about 60 persons, that is, the upper limit of the active agent is 1.0%.
It was also concluded that it is satisfactory if the evaporation residue at 105 ° C. is 2.5% or less, including other foam modifiers and active ingredients which may be added.

INDUSTRIAL APPLICABILITY The present invention relates to a liquid chemical applied to a pump type former, which has a uniform foam quality and is free from stickiness and can be easily wiped off with a composition containing a minimal amount of an active agent. Completed the prescription. Prescription was relatively easy with aerosol foams, but difficult with pump formers. Compared with the conventional aerosol type, the pump type former does not use the injection gas, so there is no risk of global environmental pollution. Since there is no waste of containers such as cans, it saves global resources.
There is no danger of explosion or fire even if used in a room with fire. Since it can be heated and used, it has the advantage that it does not feel cold to the human body.

The present invention is the result of research that enables foaming with a minimum of surfactants. Surfactants bring great benefits to the life cycle of humankind, but I wonder if we use too much? One of the causes of significant pollution of rivers is the discharge of active agents,
The septic tank also fails when the activator concentration increases. By the way, some companies have publicized that recent active agents use mild and easily decomposed fatty acids, but for that reason, vast tropical forests have been replanted with palm trees to destroy the ecology of the earth. Is the reality.
