Description

TECHNICAL FIELD The present invention relates to a foaming aerosol composition and a foaming aerosol product containing a high concentration of alcohol, which have good foaming properties and a feeling of use.

A disinfecting composition containing high-concentration alcohol is mainly used for disinfecting hands and fingers at medical sites and the like. Common usage methods include spraying a misty liquid agent from a spray container, discharging a gel agent from a pump container, and using a pump container to make a liquid agent foamy and discharge it. be done. In the mode of spraying a liquid agent, there is a problem that the liquid agent is wasted due to dripping or scattering. There is a problem that the ejection direction deviates from the Furthermore, there is also the problem that clothes and floors are stained by these. On the other hand, when the liquid agent is foamed and ejected, problems such as dripping, splashing, and ejection in a misaligned direction are unlikely to occur, and it is easy to quickly spread over the entire finger and is excellent in usability.

However, in the case of a liquid formulation containing alcohol at a high concentration, the antifoaming action of the alcohol inhibits the foam film-forming action of the surfactant and lowers the viscosity of the liquid formulation. is difficult. Therefore, in order to form foams with good usability using a liquid agent containing a high-concentration alcohol, it is necessary, for example, to add a surfactant at a high concentration or a thickener. High-concentration surfactants and thickeners may cause dry residue after application, resulting in poor usability (tactile sensation) and skin irritation. If the amount of alcohol to be blended is reduced from the viewpoint of improving foaming properties, the drying properties of the liquid formulation may decrease, resulting in a longer time required for hand disinfection or a decrease in sterilizing power.

Patent Document 1 discloses (A) an alcohol present in an amount of 50-90% by volume of the total composition, (B) bis-PEG/PPG-[14 in an amount of 0.1-10% by weight of the total composition -20]/[5-20] dimethicone, and (C) water present in an amount to make up 100% by weight of the total composition and having a pH of 5 or less. things are described.

The stock solution contains (A) an alcohol having 1 to 3 carbon atoms and (B) a polyether-modified silicone, and is filled in a container together with a propellant.

(A) Alcohol having 1 to 3 carbon atoms Examples of alcohols having 1 to 3 carbon atoms (hereinafter also referred to as "alcohol") include methanol, ethanol, isopropyl alcohol (2-propanol), n-propanol, and the like. . These may be used singly (one kind) or in combination (two or more kinds). From the viewpoint of forming foam having a low specific gravity and a good appearance, an alcohol containing ethanol is preferable, and an alcohol containing only ethanol may be used. When a mixture of ethanol and another alcohol is used, the content of ethanol in 100% by weight of alcohol is preferably 50% by weight or more, more preferably 70% by weight or more, and even more preferably 90% by weight or more. Ethanol is also excellent in that it has a high disinfection effect against hydrophilic viruses such as norovirus, and is weak in degreasing action and toxicity.

Weight % or less is more preferable.

(B) Polyether-modified silicone Polyether-modified silicone is a silicone-based foaming agent (surfactant), and acts as a foaming agent for undiluted liquids containing high-concentration alcohol. Examples of the polyether-modified silicone include polyoxyethylene type, polyoxyethylene-oxypropylene type and the like, and polyoxyethylene type is preferred.

Polyether-modified silicones include, for example, PEG3-dimethicone, PEG-9 dimethicone, PEG-10 dimethicone, PEG-11 methyl ether dimethicone, PEG-12 dimethicone, PEG32 methyl ether dimethicone, Bis-PEG3-dimethicone, Bis-PEG- Polyoxyethylene/polymethylsiloxane copolymers such as 9 dimethicone, Bis-PEG-10 dimethicone, Bis-PEG-11 methyl ether dimethicone, and Bis-PEG-12 dimethicone can be used.

Polyoxyethylene/methylpolysiloxane copolymer (POE/dimethicone copolymer) is obtained by substituting some of the methyl groups of dimethylpolysiloxane (dimethicone) with polyoxyethylene (polyethylene glycol). Polyoxyethylene-methylpolysiloxane copolymer has a linear block copolymer structure in which polyoxyethylene chains are bonded to the ends of the polydimethylsiloxane skeleton, and polyoxyethylene There is a pendant copolymer structure to which the chains are attached. From the viewpoint of forming stable foam, a polyoxyethylene/methylpolysiloxane copolymer having a linear block copolymer structure is preferred.

More preferred. From the viewpoint of suppressing stickiness when disinfecting fingers, it is preferably 3.0% by weight or less, more preferably 2.5% by weight or less, and even more preferably 2.0% by weight or less.

(C) Moisturizing agent By making an aerosol product that forms foam by discharging the undiluted solution and the propellant at a predetermined volume ratio, the amount of polyether modification is less than that of a pump product that forms foam under low pressure conditions. Silicones allow good foam formation. For this reason, the stickiness caused by the polyether-modified silicone is suppressed, so that the addition of a moisturizing agent does not increase the stickiness and does not lead to a decrease in the feeling of use.

Moisturizers include, for example, glycerin, propylene glycol, 1,3-butylene glycol, lactic acid, sodium pyrrolidonecarboxylate, and urea. Among these, glycerin, propylene glycol and 1,3-butylene glycol are preferred, and glycerin is more preferred, from the viewpoint of moisturizing properties and feeling during use.

Moisturizers may be used singly (one kind) or in combination (two or more kinds). From the viewpoint of both imparting moisturizing properties to the foam aerosol composition and suppressing stickiness during use, the content of the moisturizing agent in 100% by weight of the stock solution is preferably 2 to 8% by weight, and 3 to 7% by weight. is more preferred, and 4 to 6% by weight is even more preferred.

(propellant)
A propellant is a component that constitutes the foam aerosol composition in the container of the foam aerosol product, and is present in the container in the form of a liquid, a gas, or a mixture of gas and liquid.
From the viewpoint that the foam aerosol composition has a low foam specific gravity and forms fine foam, the content of the propellant in 100% by weight of the foam aerosol composition is preferably 22% by weight or less, more preferably 15% by weight or less. , 10% by weight or less is more preferable. The content of the propellant in 100% by weight of the foam aerosol composition is the content at the time of producing the foam aerosol product by filling the container with the stock solution and the propellant.

Propellants include liquefied petroleum gas, dimethyl ether, carbon dioxide, nitrogen, nitrous oxide, HFC-134a, HFO-1234ze (E) and the like. Liquefied petroleum gas can be used, for example, a mixture of propane, isobutane and normal butane.

Since the liquefied petroleum gas is a hydrocarbon and has a high affinity with the polyether-modified silicone in the undiluted solution, it has a low foam specific gravity and can form good fine-textured foam. Therefore, from the viewpoint of forming good foam, a propellant containing liquefied petroleum gas as a main component is preferable, and a propellant containing liquefied petroleum gas is more preferable.

In addition to the alcohol and the above-described components (A) to (C), the stock solution may contain additional components within the range that does not inhibit the above-described actions. Such components include preservatives, other surfactants, thickeners, oils, solvents, other bactericidal disinfectants, pH adjusters, fragrances, and the like.

(foam aerosol product)
The present invention can be implemented as a foam aerosol product in which a foam aerosol composition is filled in a container. The foam aerosol product of the present invention is produced by the pressure of the liquefied gas or compressed gas filled in the container, and the target substance (perfume, medicine, insecticide) other than the gas (propellant) filled in the container or another container. Among aerosol products that have the function of discharging liquids containing agents, etc., in the form of sprays, foams, toothpastes, etc., those that discharge the target substance in the form of foam.

When the container body (container) 10 is filled with the undiluted solution 32 and the propellant 31 and the valve 11 is attached, part of the liquid propellant 31L evaporates to become a gaseous propellant 31V. pressure increases. When the actuator 12 of the valve 11 is pushed down to open the valve 11, the liquid propellant 31L in the composition 33 is rapidly vaporized and discharged as the composition 33 in foam.

From the viewpoint of forming good bubbles, the pressure in the container body 10 is preferably 0.05 MPa or more and 0.80 MPa or less, more preferably 0.15 MPa or more and 0.70 MPa or less, and further 0.25 MPa or more and 0.60 MPa or less. preferable.

As the container body 10 filled with the stock solution 32 and the propellant 31, a commonly used container can be used. Although the material of the container is not particularly limited, examples thereof include pressure-resistant containers made of various metals, resins, glass, and the like.

FIG. 2 is a cross-sectional view schematically showing the structure of the valve 11. As shown in FIG. The valve 11 is a component that seals the container body 10 by fitting with the container body 10 , and includes a dip tube 13 , a housing 14 , a stem 15 , a mounting cup 17 and a spring 18 . Although FIG. 1 shows the valve 11 for upright injection as an example, the valve of the foam aerosol product 1 is not limited to this, and a valve for inverted injection or both upright and inverted may be used.

The dip tube 13 supplies the stock solution 32 (see FIG. 1) to the housing 14 and the stem 15 and at the same time suppresses the discharge amount of the stock solution 32 . A housing 14 holds the stem 15 biased against a stem gasket 19 by a spring 18 and has a housing bore 20 . The housing hole 20 is provided on the side opposite to the actuator 12 and connected to the dip tube 13 .

In addition, the shape of the housing hole 20 is not limited to the circular cross section, and may be another shape.

The stem 15 opens and closes the stem hole 21 by moving up and down to control the state of communication between the actuator 12 communicating with the stem hole 21 and the interior of the container body 10 . When the actuator 12 is pushed down and the stem 15 moves downward to open the stem hole 21 blocked by the stem gasket 19 and the valve 11 is opened, the composition 33 (see FIG. 1) flows into the dip tube 13. , is supplied into the housing 14 and discharged from the actuator 12 in the form of foam.

When the foam aerosol described above is used, the quality of the foam discharged from the foam aerosol product container is affected by the size of the stem hole 21 of the stem 15 provided in the valve 11 that seals the container body 10 . When the cross-sectional shape of the stem hole 21 is circular, the diameter (inner diameter) S of the stem hole 21 is preferably 0.1 mm or more and 0.6 mm or less from the viewpoint of discharging high-quality foam having a small foam specific gravity and fine texture. 0.2 mm or more and 0.5 mm or less is more preferable. The cross-sectional area of the stem hole 21 is preferably 0.01 mm ² to 0.30 mm ² , more preferably 0.03 mm ² to 0.20 mm ² . Also, an aerosol valve 11 having one stem hole 21 is preferable to one having a plurality of stem holes 21 .

A stock solution was prepared by mixing each component according to the compounding amount (% by weight) shown in each table below. A foam aerosol product was produced by filling a container with a foam aerosol composition consisting of a stock solution and a propellant at the ratio (% by weight) shown in each table. Each table shows the results of evaluating the foam generated by ejecting the foam aerosol composition from each foam aerosol product according to the following methods and criteria.

[Foam Density]
The formed foam was placed in a container of 25 cm ³ and weighed to determine the specific gravity of the foam.
◎: Less than 100 (g / L) ○: 100 (g / L) or more and less than 160 (g / L) △: 160 (g / L) or more ×: Unmeasurable (almost liquid state)
[Appearance of bubbles]
When determining foam density, foam appearance was evaluated based on the following criteria.
◯: The diameter of the foam is small as a whole, the uniformity is good, and the foam is solid.
Δ: Bubbles with a large diameter are scattered here and there, and the uniformity is poor.
x: Does not form bubbles.
[Feeling of use]
After the foam was rubbed into the hands, the feel immediately after the alcohol had evaporated was evaluated according to the following criteria.
◯: Good feeling in use without sliminess or stickiness.
Δ: Slightly slimy and tacky, but the slimy feeling is hard to remove when hand-washing, and the feel is poor.
x: There is a feeling of sliminess and stickiness, and the feeling of use is poor.

(Type and blending amount of foaming agent)

As shown in Table 1, by blending about 0.3% by weight of polyether-modified silicone, it is possible to form bubbles with a small specific gravity and a good appearance using a stock solution containing 70% by weight or more of ethanol. rice field. By making an aerosol product, foam can be formed using a small amount of polyether-modified silicone, so stickiness due to polyether-modified silicone did not occur. Good foam was also formed when other surfactants were used in combination with the polyether-modified silicone. By using only polyether-modified silicone or polyether-modified silicone and POE alkyl ether in combination as a foaming agent, it was possible to form non-sticky and pleasant foam.
From the results of Formulation Examples 1, 5, and 10, the amount of polyether-modified silicone compounded is preferably 2.5% by weight or less, more preferably 2.0% by weight or less, in order to form foams with a good feeling during use. It can be said.

(moisturizer)
As described above, by using the polyether-modified silicone, it was possible to form a foam that was easy to spread on the hand, was excellent in usability, and was non-sticky and gave a good feeling when used. Therefore, the effects on the foamability and feeling of use by further blending a component having a moisturizing function were evaluated.

As shown in Table 2, all of the foam aerosol compositions containing glycerin, propylene glycol, and 1,3-butylene glycol were able to form foams with excellent usability, like those containing no moisturizing agent. The feeling of use was also good.
A foam aerosol composition containing no polyether-modified silicone could not form foam even when the contents of other surfactants and glycerin were increased.

(propellant)
Foam aerosol compositions and foam aerosol products were prepared and evaluated for foam using LPG and non-LPG propellants with different propane contents (wt %).

From the results of Formulation Examples 21 to 25, it was found that by setting the weight ratio of the stock solution/propellant to 98/2 to 78/22, foam with a low foam specific gravity can be formed. However, the foam aerosol product with a weight ratio (stock solution/propellant) of 93/7 had a low foam specific gravity and a good appearance, whereas the weight ratio (stock solution/propellant) was 78/78. The foam aerosol product No. 22 had a low foam specific gravity, but was a foamy foam with a poor appearance. Therefore, the content of the propellant in 100% by weight of the foam aerosol composition is preferably 22% by weight or less, more preferably 18% by weight or less, and even more preferably 8% by weight or less. In addition, by blending 3% by weight of the propellant, it was possible to form bubbles with a low foam specific gravity and a good appearance. The above is preferable.

As shown in Formulation Examples 37 to 39, it was possible to form foams with low foam specific gravity (g/L=mg/cm ³ ) using propellants other than LPG. LPG is preferable as the propellant from the viewpoint of forming good-looking foam having a specific gravity of 100 (g/L) or less. The foamability of the foam aerosol composition did not change depending on the content of propane in LPG composed of propane and butane.

From the results of Formulation Examples 27 and 30 to 36, it is preferable to set the internal pressure of the container to 0.8 MPa or less in order to form foam with a low specific gravity. Since there is no tendency for the specific gravity of the foam to increase due to a decrease in the internal pressure of the container, the internal pressure of the container should be set to a pressure at which the stock solution can be discharged or higher.

(Amount and type of alcohol)
Using the stock solutions and propellants shown in Table 5, foam aerosol products were produced and foam evaluated.

A foaming aerosol composition with good foamability could be prepared using a stock solution with an alcohol content of 55% by weight or more and 90% by weight or less. From the viewpoint of forming foam with a low specific gravity and good appearance, the content of alcohol in the stock solution is preferably 60% by weight or more and 80% by weight or less.
The foaming aerosol composition of Formulation Example 43, which used only isopropyl alcohol as the alcohol, was also able to form bubbles whose specific gravity was measurable. However, from the viewpoint of foamability, ethanol is more preferable than isopropyl alcohol.

(diameter of stem hole)
Using the stock solutions and propellants shown in Table 6, foam aerosol products with stems of different diameters and number of holes were produced and evaluated for foam.

As shown in Table 6, it was found that the diameter and number of stem holes on the actuator side varied the specific gravity of the foam expelled from the foam aerosol product. When the stock solutions shown in Table 6 were used, by setting the diameter (inner diameter) of the stem hole having a circular cross section to 0.3 mm or more and 0.5 mm or less, foam having a low specific gravity and a good appearance could be formed. However, when the diameter of the stem hole was set to 0.6 mm, the foam specific gravity of the foam formed by the foam aerosol product increased and the appearance of the foam deteriorated. Therefore, from the viewpoint of forming good bubbles, the diameter of the stem hole is preferably 0.1 to 0.6 mm, more preferably 0.3 to 0.5 mm. The cross-sectional area of the stem hole is preferably 0.01-0.30 mm ² , more preferably 0.07-0.20 mm ² . Also, one stem hole is more preferable than two (plural). The size (inner diameter) of the dip tube and the housing hole on the side of the dip tube did not affect the specific gravity and appearance of the foam discharged from the foam aerosol product.

(foaming pump)
A foaming pump (F5 pump foamer (Takemoto Yoki Co., Ltd.)) was used to foam the stock solution shown in Table 7, and the foam was evaluated.

As shown in Formulation Examples 51-54, when a foaming pump is used, 1-3% by weight of polyether-modified silicone cannot form a foam, and 5-10% by weight of polyether-modified silicone is required to form a foam. An ether modified silicone was required. As a result, the feeling of use deteriorated due to the stickiness caused by the polyether-modified silicone. In the present invention, by making a foam aerosol product instead of a pump product, the amount of polyether-modified silicone required for foam formation is reduced and stickiness is suppressed. As a result, a moisturizing agent can be added, and a foaming aerosol composition that has a high skin-protecting function and a good feel when used can be realized.

(Evaluation of sterilization performance by palm stamp method)
From the aerosol product of Formulation Example 11 shown in Table 2, 1.0 g of the foamy aerosol composition was taken out on the palm and dried while rubbing both hands together. Since the foam had a small specific gravity and fine texture, the aerosol composition could be quickly spread without adhering to areas other than the palm of the hand.
Before and after sterilization, the palm is brought into contact with a hand-shaped standard agar medium, and after transferring the bacteria on the palm to the medium, the medium is left at 35 ° C. for 48 hours, and then the number of colonies (CFU; colony forming unit ) were counted. The number of colonies in the medium in which the palm was contacted before sterilization was 135 (135 CFU/hand), while the number of colonies in the medium in which the palm was contacted after sterilization was 8 CFU/hand. of aerosol products showed sufficient sterilization effect.

The foam aerosol compositions and foam aerosol products of the present invention can be used for hand disinfection. Since it foams well and is excellent in usability, and the feeling of use immediately after drying is also good, it is useful for use in places where it is necessary to frequently disinfect hands and fingers, such as medical institutions.
