The present invention relates to a spray composition that forms a fast-breaking foam when sprayed. In general, for certain lotions, hair cosmetics, etc., it is required that the medicinal solution stay at the application site for a suitable period of time, and for this purpose, spray compositions that form rapid-breaking foam have been developed. There is. Conventionally, such fast-breaking foam-forming propellant compositions have been prepared using a propellant consisting of liquefied petroleum gas, liquefied lower halogenated hydrocarbons or liquefied dimethyl ether, or mixtures thereof, and a propellant soluble only in alcohol, water and/or one or more of these. It is composed of a stock solution containing a special surfactant that is
Those described in JP-A No. 45-32053 and JP-A No. 45-37291 are known. However, in these rapid-bursting foam-forming injection compositions, the foam formed is easily influenced by external conditions such as temperature and pressure, and in particular, the rapid-bursting properties of the foam formed are highly dependent on temperature. For example, the foam break time (foam disappearance time) is different in winter and summer.
In addition, foam formation is greatly influenced by external conditions, and as a result, it is not always possible to obtain stable foam forming ability or foam breaking properties (defoaming properties). In addition, conventional spray compositions use a stock solution containing alcohol, water, and surfactants, but this stock solution before adding liquefied gas is a cloudy and non-uniform liquid at room temperature, so it is separated into containers. When pouring, it is necessary to heat the stock solution to make it homogeneous, and when mass-producing on an industrial scale, operations and equipment for this heating are required, which is disadvantageous. Furthermore, in conventional foam-forming propellant compositions,
Since liquefied gas is used as a propellant, the composition of the stock solution mixed with it and the mixing ratio of each constituent component are limited to an extremely narrow range, and therefore the composition and constituent components can be adjusted within a wide tolerance range with a large degree of freedom. Since it is not possible to select a mixing ratio of The present invention was completed as a result of intensive research to eliminate the above-mentioned drawbacks, and its purpose is to have low temperature dependence of foam-forming and foam-breaking properties, and to improve composition and composition. A quick-breaking foam-forming injection composition that allows the mixing ratio of the parts to be selected over a wide range and that allows the stock solution to be obtained as a uniform liquid at room temperature, and that forms fast-breaking foam when sprayed. It's about providing things. The feature of the present invention is that 35 to 80% by weight of a monohydric alcohol having 1 to 3 carbon atoms;
A propellant consisting of 0.2-15% by weight of a surfactant of the polyoxyethylene alkyl ether type soluble in water or alcohol or mixtures thereof, 30-80% by weight of water and 0.1-4.0% by weight of compressed gas. and the viscosity of the mixed solution containing the alcohol, surfactant, and water at a temperature of 20°C is 200°C.
〜4000cps, and the pressure caused by the propellant is 3〜4000cps.
8 Kg/cm 2 and is at the point where it is injected to form a fast-breaking foam. The present invention will be specifically explained below. In the present invention, a monohydric alcohol having 1 to 3 carbon atoms, a polyoxyethylene alkyl ether type surfactant dissolved in water, alcohol, or a mixture thereof, and water each have a proportion of 35% to the total. ~80wt%, 0.2~15wt% and
A stock solution consisting of a homogeneous mixed solution with a viscosity within the range of 200 to 4000 cps at a temperature of 20°C, which is obtained by mixing to a concentration of 30 to 80% by weight, or by mixing and dissolving additives added depending on the purpose. Prepare
Add 0.1 to 4.0% by weight of a propellant consisting of compressed gas to this.
combination within the range of 3 to 8 depending on the propellant.
A fast-breaking foam-forming propellant composition is made in such a way that a pressure of Kg/cm 2 is obtained. In the above, monohydric alcohols include methanol, ethanol, n-propanol, and isopropanol, but ethanol is preferable because it is free of toxicity and odor. The proportion of this monohydric alcohol to the entire composition is 35
-80% by weight, preferably 40-65% by weight. In the stock solution, other solvents can be added as long as they do not exceed this alcohol content. Examples of this solvent include those that are soluble in both water and lower alcohols and provide a uniform stock solution, such as ketones such as acetone and esters such as acetate. As the surfactant, a polyoxyethylene alkyl ether type surfactant is used. Specific examples include polyoxyethylene cetyl ether, polyoxyethylene lauryl ether, polyoxyethylene stearyl ether, polyoxyethylene oleyl ether, and polyoxyethylene alkyl ether. Specifically, the most preferable one is one in which the number of moles of added ethylene oxide is 4 to 10 (this is referred to as "POE (4 to 10)").
It is expressed as follows. The same applies below. ) and at least one of polyoxyethylene cetyl ether POE (2-10), polyoxyethylene oleyl ether, and polyoxyethylene lauryl ether POE (2-15). Can be done. The proportion of this surfactant in the total composition is 0.2 to 15% by weight, preferably 0.3 to 0.8%.
Weight%. The proportion of water in the stock solution is 30% of the total composition
-80% by weight, preferably 45-60% by weight. It is also possible to use polyhydric alcohols such as propylene glycol, glycerin, and sorbitol together with this water. The viscosity of the stock solution is 200 to 200°C at a temperature of 20°C.
It may be 4000 cps, but 600 to 2500 cps is particularly preferable. The compressed gas used as a propellant to be combined with the stock solution may be a gas such as nitrogen gas, helium gas, argon gas, carbon dioxide gas, or nitrous oxide gas, or a compressed mixture thereof. This compressed gas is used in a proportion of 0.1 to 4.0% by weight based on the entire composition, but preferably
0.30 to 1.0% by weight, so that the resulting pressure is 3 to 8 kg/cm 2 , preferably 4 to 7 kg/cm 2 . The quick-breaking foam-forming injection composition of the present invention is as described above, and is made into an aerosol product by filling it into an aerosol container. When this aerosol is sprayed by itself, it forms fast-breaking foam. formed,
This foam breaks down and becomes a complete liquid after about 3 to 180 seconds without applying any particular pressing force or shearing force. Also, unlike normal aerosol spraying, the required amount of contents can be sprayed onto the required area. In the present invention, a compressed gas whose pressure state has extremely low temperature dependence is used instead of a liquefied gas as a propellant. The properties are little affected by external conditions, particularly temperature, and a stable state or characteristic foam-forming ability and foam-breaking ability can be obtained at both high and low temperatures. In addition, in the stock solution in which the propellant is combined, the alcohol used is a monohydric lower alcohol,
Since the surfactant is soluble in alcohol, water, or a mixture thereof, the viscosity of the stock solution is 200 to 4000 cps at a temperature of 20°C and the pressure of the propellant is 3.
Within the range of ~8Kg/ cm2 , it is possible to make the composition exhibit a uniform liquid phase by applying pressure from the propellant, and it is possible to use it industrially while ensuring safety in handling. This is extremely advantageous for mass production on a large scale. Furthermore, in the rapid-rupture foam-forming injection composition of the present invention, compressed gas is used as the propellant;
Restrictions on the stock solution are significantly relaxed, and the tolerance range for its composition and mixing ratio of constituent components is wide.
Therefore, not only the desired foam-forming ability and foam-breaking ability can be obtained, but also a large degree of freedom can be obtained in terms of dosage form, and spray compositions suitable for various uses such as pharmaceuticals and cosmetics can be created as needed. can do. In addition to the above, by using a polyoxyalkyl ether type surfactant in the stock solution, the solution obtained by mixing it with a lower alcohol and water will thicken and have a viscosity within the above-mentioned range. It is easy to obtain, provides an excellent feeling of use without stickiness, and also has a certain degree of foam persistence. It can form a sexual foam. On the other hand, a method of increasing the viscosity by adding a polymer compound or resin is also known, but this method has a poor feeling of use and tends to become sticky. In order to achieve the various effects mentioned above,
It is necessary that the above-mentioned conditions for the stock solution and propellant be satisfied, and favorable results cannot be obtained outside these ranges. That is, if the proportion of monohydric alcohol is less than 35% by weight, the stock solution will not be a uniform liquid, and the foam forming property when sprayed will be low. On the other hand, if this ratio exceeds 80% by weight, the stability of the foam formed will be low and the time it takes to break the foam will be extremely short. If the proportion of the polyoxyethylene alkyl ether type surfactant is less than 0.2% by weight, the foam forming property will be low, and if it exceeds 15% by weight, the viscosity will become excessive and the stability of the foam will increase significantly, resulting in rapid breakage. Gender is lost. Water shows the opposite tendency to the lower alcohol,
If the proportion is less than 30% by weight, the stability of the foam will be low, and if it exceeds 80% by weight, the stock solution will not be a uniform liquid and no rapid-breaking foam will be formed when sprayed. The proportion of compressed gas forming the propellant is 0.1% by weight
If it is less than 4.0% by weight, it will be difficult to obtain the required minimum pressure of 3Kg/cm 2 and it will be difficult to inject all the contents of the aerosol container, and if it exceeds 4.0% by weight, the pressure will exceed 8Kg/cm 2 . Increased risk. Considering the various circumstances mentioned above, the proportion of lower alcohol is 35 to 60% by weight, the proportion of water is 45 to 60% by weight, and the proportion of polyoxyethylene alkyl ether type surfactant is 0.2 to 0.5% by weight. , the viscosity of the stock solution is 600~2500 cps at a temperature of 20℃, the proportion of compressed gas as propellant is 0.3~1.0% by weight, and the resulting pressure is 4~2500 cps.
A value of 7.5 Kg/cm 2 is practically preferred. As described above, according to the present invention, the foam forming ability and foam breaking ability are always stable, almost unaffected by external conditions, especially temperature, and it is advantageous for mass production, and the composition and the mixing of constituent components. A fast-breaking foam-forming propellant composition can be provided which provides a relatively large degree of freedom. Examples of the present invention will be described below, but the present invention is not limited thereto. Examples 1 to 18 A total of 18 types of injection compositions of the present invention were prepared according to the component ratios shown in the table. Examples 6 and 7 are for aftershave lotion, 8 is for pest repellent, 9 and 10 are for baby lotion, 11 is for cologne, 12 is for treatment, 13 is for hair color, 14 is for hair shine, 15 is for sunscreen lotion, 16 is for hair conditioner, 17 is for hair tonic, and 18 is for ointment. In the table,
"POESE" is polyoxyethylene stearyl ether, "POELE" is polyoxyethylene lauryl ether, "POECE" is polyoxyethylene cetyl ether, "POEOE" is polyoxyethylene oleyl ether, and "POEAE" is polyoxyethylene alkyl ether. represent Moreover, both pressure and viscosity are values at a temperature of 20°C.

When the time required for this to occur was measured, it was 14 seconds at a temperature of 5°C and 7 seconds at 20°C. In contrast, in the composition of Example 1, instead of all the carbon dioxide gas and part of the ion-exchanged water, a liquefied gas, Freon, was used at a ratio of 8% by weight to prepare an injection composition, and the same measurement was carried out. As a result, a significant difference was observed between 360 seconds at a temperature of 5°C and 30 seconds at 20°C. Further, in each of the other Examples, stable rapid rupture properties were obtained regardless of temperature, similarly to Example 1.
