Description

  The present invention relates to a composition and a container thereof. Specifically, the present invention relates to high viscosity compositions, particularly high viscosity cleaning compositions and containers thereof. The present invention also generally relates to a foam-generating dispenser.

  High viscosity compositions such as dishwashing compositions, hand soap compositions, hair conditioner compositions, fabric conditioner compositions, polishing compositions and the like are well known and have typically been provided in liquids, gels or pastes. Liquids and pastes may be useful in various situations, but such physical forms are no longer considered new or exciting. It is also desirable to provide new and interesting physical forms, but the use of such compositions typically involves applying or pre-applying such liquids, gels and pastes to a substrate and then adding Limited to applying directly to the desired surface in stages.

  Although it is known to use foam-generating dispensers to make foams of low viscosity compositions, this method has not been successful so far for high viscosity compositions. In particular, the rheology of the highly viscous composition makes it difficult to achieve an acceptable foam without vigorous turbulence and turbulence characteristics. Such turbulence characteristics often require more physical effort or high-pressure containers, so as a practical result, to match the limits of the foam-generating dispensers currently on the market, Often the formulator is required to lower the viscosity. Thus, this method places artificial and physical constraints on the formulator's privilege to achieve the best performance and / or lowest cost composition.

  Therefore, there is a need for a foam-generating dispenser that can generate foam even from highly viscous compositions. Furthermore, there is a need for a foam-generating dispenser that can generate such foam without undue physical effort and / or without the need to use aerosol propellants.

  The present invention relates to a foam production kit comprising a non-aerosol container having a foam production dispenser, and preferably a highly viscous composition in the container. The highly viscous composition has a viscosity of at least about 0.05 Pa · s. The foam-generating dispenser, when used with a highly viscous composition, produces foam having a foam (ie volume) to weight ratio greater than about 2 ml / g.

  It has now been found that the combination of a foam-generating dispenser and a highly viscous composition can simultaneously provide an acceptable foam without undue physical effort and the use of aerosol propellants. While not intending to be limited by theory, it is believed that if a turbulent channel is created gradually, even a highly viscous composition having a viscosity of at least 0.050 Pa · s can produce an acceptable foam. ing.

(container)
Containers useful herein are non-aerosol containers, typically having a hollow body to hold a highly viscous composition, preferably a dishwashing composition, typically plastic, glass, and / or Or a bottle or can formed of metal, preferably formed of a polymer or resin such as polyethylene, polypropylene, polyethylene terephthalate, polycarbonate, polystyrene, ethyl vinyl alcohol, polyvinyl alcohol, thermoplastic elastomer, and combinations thereof. However, other materials known in the art may be used. Such containers typically hold from about 100 milliliters to about 2 liters, preferably from about 150 milliliters to about 1.2 liters, more preferably from about 200 milliliters to about 1 liter of liquid consumer. It is well known for holding products. Such containers are widely available from a number of packaging suppliers.

  Operatively attached to the container either directly or indirectly is a foam generation dispenser for generating foam. When activated, the foam-generating dispenser generates foam and at the same time dispenses the foamed composition from the container. The foam-generating dispenser may be formed integrally with the container or formed separately. When formed separately, the foam-generating dispenser can be a transition piece, corresponding threaded male and female members, pressurized and pressureless seals, clamping and snapping parts, and / or known in the art. It can be attached to the container by methods known in the art, such as employing other methods. Preferably, the foam-generating dispenser is attached to the container with transition pieces and / or corresponding threaded, easily refillable male and female members.

  The foam-generating dispenser can interact with the highly viscous composition by any method for generating foam, such as chemical reactions, enzymatic reactions, and / or mechanical actions. However, mechanical action is preferred herein, and typically, when dispensing a dishwashing composition, a gas such as air, nitrogen or carbon dioxide is directly applied or mixed in a turbulent manner into the foam. Including the intended mechanism of physically forming the. Preferably, the foam generation dispenser injects or imparts air from the atmosphere into the dishwashing composition, an air injection piston, foam generation opening, impingement surface, mesh or net, pump, and / or nebulizer, more preferably air injection. Includes a mechanism for applying gas to form bubbles from air by means of pistons, pumps, impingement surfaces, multiple meshes or nets, and / or atomizers. In a particularly preferred embodiment, the foam-generating dispenser uses at least 3, preferably 3-5 meshes, and the highly viscous composition flows continuously through these meshes to produce foam. Without intending to be limited by theory, by continuously flowing through the mesh, the highly viscous composition is repeatedly turbulently mixed with air, thereby exceeding the effects of any single mesh. It is thought that the foam generation effect is amplified. As the viscosity of the highly viscous composition increases, additional mesh may be added to provide the desired level of foaming and / or foam quality.

  The foam-generating dispenser is also typically an activator, preferably, for example, a trigger, a pressure activated pumping mechanism, a button, and / or a slider, more preferably activatable with a single finger Manual activators such as buttons and / or pressure activated pumping mechanisms. It is particularly preferred that the activator is designed to be easily activated by the consumer when the hand is wet and / or slippery, such as during a dishwashing process. Such an activator should be such that the user can easily and conveniently control both dispensing speed and dispensing volume. For certain applications, such as industrial or public facilities, other activators such as electronic activators, computer controlled activators, phototubes or infrared sensing activators, manual lever assist activators may also be useful. Foam generating dispensers useful herein have a foam to weight ratio of greater than about 2 ml / g, more preferably from about 3 ml / g to about 10 ml / g, and even more preferably from about 4 ml / g to about 8 ml / g. Produces a foam having Further, the foam-generating dispenser useful herein produces at least about 2 ml, preferably from about 3 ml to about 10 ml, more preferably from about 4 ml to about 8 ml of foam per ml of dishwashing composition. “Cream-like” and “smooth” foams with fine bubbles dispersed relatively uniformly throughout may be particularly preferred due to their aesthetic and / or performance characteristics. In some cases, preferred bubbles are particularly preferred that do not remarkably return to liquid for more than 3 minutes. Specifically, when the foam is dispensed onto a clean glass surface (eg, Pyrex® plate) and left at 25 ° C. for 3 minutes, the liquid that appears should be less than 1 mm. Preferably, after 3 minutes no liquid is seen at the edge of the foam. However, in other cases, it has also been found that a certain amount of liquid (i.e., no foam) is also preferred, as this liquid then penetrates into the applicator (e.g. sponge), e.g. This is because when used for cleaning, the use distance of the highly viscous composition is further extended.

  FIG. 1 is a cut-away view of a preferred embodiment, wherein a foam-generating dispenser 10 has a nozzle 12 from which a foamed dishwashing composition is dispensed. The dishwashing composition enters the foam-generating dispenser through the dip tube 14 and flows past the ball 16 and into the cylinder 18. The plug 20 prevents the ball 16 from escaping and supports the coil spring 22 and the inner rod 24. The liquid piston 26 creates suction that pulls the dishwashing composition past the ball 16 and plug 20 into the liquid chamber 28, thereby preparing the foam-generating dispenser 10. On the other hand, when the air chamber 30 and the air piston 31 are also prepared and the activator 32 is pushed down, both the air from the air chamber 30 and the dishwashing composition from the liquid chamber 28 enter the mixing chamber 34 in a turbulent state. Passed through the first mesh 36 and the second mesh 38, both pushed and held in place by the mesh holder 40. As the turbulent air / dishwashing composition mixture passes through the first mesh 36, a first coarse foam is produced, which is finer after passing through the second mesh 38 and the third mesh 41. And become uniform. These meshes may have the same pore size or different pore sizes. Further, an additional mesh may be adopted as desired.

In preferred embodiments, the foam-generating dispenser comprises a sponge in or attached thereto, either instead of or in addition to one or more meshes. Sponges also create bubbles when the highly viscous composition turbulently passes through its open cell structure. Such a sponge may be included within the foam-generating dispenser and / or placed at the end of the nozzle, as desired. While not intending to be limited by theory, additional meshes and / or sponges placed slightly in and / or at the tip of the nozzle serve to generate bubbles immediately prior to dispensing, so Was found to be particularly useful. Thus, the user sees the desired foam with the best foam quality when passing through or just after the last turbulent region, and before the significant deterioration and / or quality change.
FIG. 1 also shows a base cap 42 that secures the foam-generating dispenser to a container 44 that holds the highly viscous composition.

  While a trigger type foam-generating dispenser may be preferred in certain embodiments herein, a finger and / or palm activated pump (see FIG. 1) is preferred for aesthetic reasons. Many. This is especially true when the foam generation kit is to be distinguished from a “rough” image of typical hard surface cleaners and similar powerful products.

  There may be solvents that can reduce product viscosity and / or solvents that can impart shear-thinning or non-Newtonian rheological properties to the composition, but such solvents are typically expensive and prominent It does not provide a shearless related effect and is not preferred herein. Therefore, in a preferred embodiment, the high viscosity composition herein moves as a Newtonian fluid over the relevant shear range while being used in a foam-generating dispenser.

  Preferred solvents useful herein that provide Newtonian behavior include mono-, di- and polyhydric alcohols, ethers, and mixtures thereof. Also preferred are alkyl carbonates such as propylene carbonate.

  Enzymes useful herein include cellulase, hemicellulase, peroxidase, protease, gluco-amylase, amylase, lipase, cutinase, pectinase, xylanase, reductase, oxidase, phenol oxidase, lipoxygenase, ligninase, pullulanase, tannase, pentosanase, Malanases, β-glucanases, arabinosidases, and mixtures thereof are included. A preferred combination is a detergent composition having a cocktail of conventionally applicable enzymes such as proteases, amylases, lipases, cutinases, and / or cellulases. The enzyme is typically present at about 0.0001% to about 5% by weight of active enzyme. Preferred proteolytic enzymes are selected from the group consisting of ALCALASE®, Novo Industri A / S, BPN ′, Protease A and Protease B (Genencor), and combinations thereof Is done. Protease B is more preferred. Preferred amylase enzymes include TERMAMYL®, DURAMYL®, and WO 94 / 18314A1 (Antrim et al., Published Aug. 18, 1994, Genencor International). And International Publication No. 94 / 02597A1 (Svendsen and Bisgard-Frantzen, published February 3, 1994, Novo Nordisk A / S) Amylase enzymes described in (Transfer). Further non-limiting examples of preferred enzymes are disclosed in WO 99/63034 A1 (Vinson et al., Published 9 December 1999).

  Microemulsion or protomicroemulsion compositions, and particularly dishwashing compositions, are also typically less than about 5,000 ppm by weight of low water soluble oil, preferably from about 0 parts per million (ppm) to about 1,500 ppm, More preferably, it contains a low water soluble oil having a solubility in water of about 1 part to about 100 ppm per billion. Preferred low water soluble oils useful herein include terpenes, isoparaffins, other oils having the aforementioned solubility, and mixtures thereof.

Without a foam-generating dispenser, the dishwashing composition herein has an effective foam dilution range with a dilution range typically less than about 50%, preferably from about 0% to about 40%, more preferably from about 0% to about 35%. Have However, in embodiments of the invention herein, the dishwashing composition, when used with a foam-generating dispenser, is at least about 50%, preferably about 50% to about 100%, more preferably about 75% to about It has an effective foam dilution range of 100%, even more preferably from about 85% to about 100%. The effective foam dilution range is calculated as follows. The soap foam generation curve of Graph I is produced by testing various dilutions of the dishwashing composition according to the soap foam cylinder test herein. Such a curve can be created with or without dispensing from the foam-generating dispenser into the cylinder. As used herein, “effective foam” is defined as the foam produced for a given dishwashing composition at least half the maximum volume (50%) of the soap foam production curve. Therefore, in Graph I for when the foam-generating dispenser is not used, effective foam is formed at a product concentration of about 28% to about 2%, which is an effective foam dilution range of 26% (ie, 28% to 2%). However, when the same dishwashing composition is used (ie, dispensed) with a foam-generating dispenser, effective foam is produced until a product concentration of about 3% is reached from the point of dispensing (100% product concentration). You can see it done. This is because the dishwashing kit produces foam at a dilution of the dishwashing composition in water that is significantly different from the dilution at which the maximum volume of foam is formed by the soap foam cylinder test. Thus, the effective foam dilution range when the dishwashing composition of Graph I is dispensed from the foam dispenser is 97% (ie, 100% to 3%).

  The dishwashing compositions useful herein have an oil solubilization curve created by the oil solubilization test as defined herein. An “effective oil solubilization amount” is herein defined as at least 20% of the maximum oil solubilization amount for a given dishwashing composition, according to an oil solubilization curve plotted as a function of product concentration (ie, dilution). Defined as oil solubilization amount. Thus, in Graph I, the maximum oil solubilization amount is about 4.7 at 70% product concentration, and thus the effective oil solubilization amount is at least about 0.94. Effective oil solubilization occurs in a dilution range of about 96% to about 42%, which translates to an effective oil solubilization dilution range of about 54%.

  As can be seen in Graph I, there is virtually no overlap between the soap foam generation curve without the foam generation dispenser and the effective oil solubilization dilution range. Similarly, without a foam-generating dispenser, it can be seen that there is no overlap between the effective foam dilution range (28% to 2%) and the effective oil solubilization dilution range (42% to 96%). In contrast, when a foam-generating dispenser is employed, the effective foam dilution range (3% -100%) completely (100%) overlaps the entire effective oil solubilization dilution range (42% -96%). In a preferred embodiment, the effective foam dilution range overlaps the effective oil solubilization dilution range, preferably by at least 10%, more preferably by only about 25% to about 100%, especially in the case of microemulsions or protomicroemulsions, Even more preferably, the effective oil solubilization dilution range overlaps by about 50% to about 100%. Furthermore, it is particularly preferred that the effective foam dilution range overlaps with the point of maximum oil solubilization in the oil solubilization curve. Thus, the present invention encourages users to use the product at a concentration / product dilution that will solubilize the oil more effectively and thus optimize cleaning.

  In order to achieve foaming that is acceptable to consumers at dilutions where oil solubilization curves are more effective, preferably maximized, such dishwashing compositions, particularly microemulsion and protomicroemulsion dishwashing compositions, It has been recognized in the present invention that a container and the foam-generating dispenser herein are required. Thus, when the dishwashing composition is used with a container and foam-generating dispenser, it is preferred that the effective foaming be produced at a dilution factor that is significantly different from the soap foam generation curve when the container and foam-generating dispenser are not used.

  Dishwashing compositions, cleaning compositions, protomicroemulsion compositions, and microemulsion compositions useful in the present invention are described, for example, in WO 96 / 01305A1 (Farnworth and Martin, 1996).

It is particularly preferred that the dishwashing composition or a variation of the composition described in the above references be used in combination with the container and foam-generating dispenser described herein.

Foam is created when the highly viscous composition is dispensed from the foam-generating dispenser.

  The highly viscous composition is preferably sold as a single item in the container as a refill composition, but this is not necessary and separate components within the same kit are contemplated herein.

(Molding applicator)
It has further been found that molded applicators can provide surprisingly significantly improved results and ease of use compared to standard applicators. Molded applicators are designed and sized to be used to easily hold and apply foamed dishwashing compositions to surfaces to be cleaned, i.e. tableware. When the foamed dishwashing composition is applied to a flat applicator, the foamed dishwashing composition is quickly wiped over the first contact tableware and the next dishwashing is washed It has been found that little dishwashing composition remains on the flat applicator. This adds to the cost of using a foamy cleaning and / or dishwashing composition because the distance of use of the composition is significantly reduced, and a new foaming cleaning and / or dishwashing composition on a flat applicator. It is both cumbersome because it must always be applied to. In contrast, a molded applicator that includes a receiving area, such as a protective dimple and / or pocket for the foamed dishwashing composition, more effectively retains the foamed dishwashing composition and distributes it over time.

  Since molded applicators are often used for scrubbing, it is preferred that at least one of its surfaces includes an abrasive surface. Molded applicators are typically natural or artificial sponges, brushes, metal polishers, woven materials, non-woven materials, abrasive materials, plastic materials, fabric materials, microfiber cleaning materials, polymer materials, resin materials, rubber materials Or combinations thereof, preferably natural or artificial sponges, brushes, metal polishes, abrasive materials, foam rubber materials, functional absorbent materials (FAM), polyurethane foams, and combinations thereof, and more preferably natural Or it is selected from porous materials such as artificial sponges, brushes, abrasive materials, foamed rubber materials, and combinations thereof, and open cell structures are particularly preferred for all types. Such molding applicators are available from a variety of vendors, such as Minnesota Mining and Manufacturing Company (3M), St. Paul, Minnesota, USA. and so on. Where the molding applicator is formed of a relatively delicate or fragile material, the material is preferably partially or fully covered with a water permeable, stiffer material such as a nonwoven material. Also useful are surfaces formed of plastic or polymeric materials, such as Minnesota Mining and Manufacturing Company; 3M, St. Paul, Minnesota, USA. And those found in, for example, Scotch-Brite ™ general purpose polishing pads.

The FAMs useful herein have an absorption capacity that is preferably greater than about 20 gH ₂ O / g, more preferably greater than 40 gH ₂ O / g, based on the weight of the FAM. Such preferred FAMs are described in US Pat. No. 5,260,345 (DesMarais et al., Issued November 9, 1993), or US Pat. No. 5,889,893 (Dyer et al., 1999). Issued on May 4, 2000). Examples of preferred polyurethanes are US Pat. No. 5,089,534 (Thoen et al., Issued February 18, 1992); US Pat. No. 4,789,690 (Milovanovic-Lerik et al.). , Issued December 6, 1988); Japanese Patent Publication No. 10-182780 (Japanese Patent Publication No.10-182780) (Kao Corporation, published July 7, 1998); Japanese Patent Publication 9-30215 ( Japanese Patent Publication No.9-30215) (Yokohama Gum) (published February 4, 1997); Japanese Patent Publication No. 5-70544 (Japanese Patent Publication No.5-70544) The Dow Chemical Company), published March 23, 1993); and Japanese Patent Publication No. 10-176073 (Bridgestone Company, June 30, 1998). It is described in published).

  Preferably, the molded applicator is not rigid, but rather has at least one resilient portion, preferably a resilient portion covered with an abrasive surface. Such an optional resilient portion allows the user to change the amount of contact, pressure, etc. between the rubbing surface and the tableware. Accordingly, the foamed dishwashing composition is preferably applied directly into or on the molded applicator from the foam-generating dispenser.

  Referring to FIG. 2, there is shown a top perspective cutaway view of the molding applicator 12 of the preferred embodiment herein, the sponge-type molding applicator 12 includes a receiving area 50 in which the foamed dishwashing is performed. The composition is applied and used. Thus, the receiving area 50 is typically bounded by a wall 52 that prevents the foamed composition from being rapidly scraped away from the molding applicator 12. The receiving area may be of any shape and design that holds the foamed dishwashing composition in contact with the molding applicator, but is preferably a concave depression in the molding applicator. In a preferred embodiment, the receiving area includes a relatively steep concave wall or other structure that effectively retains the foamed detergent within the receiving area and distributes it over normal use times. The receiving area typically holds the foamed dishwashing composition from about 1 ml to about 200 ml, preferably from about 2 ml to about 150 ml, more preferably from about 5 ml to about 100 ml.

  In FIG. 2, the molded applicator 12 further includes a plurality of abrasive surfaces 54 for rubbing tableware. It is particularly preferred that at least one abrasive surface is provided on the molding applicator.

Has been. The foamed dishwashing composition is applied through the mouth 56 to the receiving area 50, although the mouth may remain permanently open or closeable, as desired. Abrasive surface 54 covers substantially the entire exterior of molded applicator 12 and helps remove dirt from the dishes.

(Test method)
Viscosity herein is measured at 20 ° C. with a Brookfield viscometer model # LVDVII +. The spindle used for these measurements is an S31 spindle with a speed suitable for measuring products of various viscosities, for example, 12 rpm for measuring products with a viscosity exceeding 1 Pa · s and a viscosity of 0.1. 30 rpm for products of 5 Pa · s to 1 Pa · s, and 60 rpm for measurements of products with a viscosity of less than 0.5 Pa · s.

  To measure solubilization capacity, 10.0 g of the product to be tested (if the test is performed at a specific dilution, this amount includes water) is placed in a 25 mL scintillation vial. To this, 0.045% Pylakrome RED-LX1903 (SOLVENT RED 24CAS # 85-83-6 and SOLVENT RED 26CAS # 4477-79-6 mixture, Add 0.1 g of food canola oil dyed with dye (available from Pylam Products, Tempe, Arizona, USA) and cap the vial. The vial is shaken vigorously by hand for 5 seconds and placed until clear by the ISO 7027 turbidity measurement procedure, or until 5 minutes have passed, whichever comes first. The ISO 7027 method measures turbidity at a wavelength of 880 nanometers with a turbidity measurement facility, such as that available from Omega Engineering, Inc. of Stamford, Connecticut, USA. Once the vial is clear, additional oil is added in 0.1 g increments until the vial does not become clear within a specified time. The percentage of oil dissolution is recorded as the maximum amount of oil that was successfully solubilized by 10.0 g of product (ie, the vial becomes clear). The dishwashing compositions herein preferably have at least about 1 g of dyed canola oil, more preferably at least about 3 g of dyed canola oil, even more preferably at least about 4 g when tested at a product concentration of 75%. Solubilized canola oil.

  Foaming properties can be measured by employing a soap bubble cylinder tester (SCT) and using the data to plot a soap bubble generation curve. The SCT has a set of four cylinders. Each cylinder is typically 30 cm long and 10 cm in diameter. The cylinder wall is 0.5 cm thick and the cylinder bottom is 1 cm thick. SCT rotates the test solution in a closed cylinder, typically a plurality of clear plastic cylinders, at a speed of about 21 revolutions per minute for 2 minutes, after which the foam height is measured. The test solution can then be soiled, stirred again, and the resulting foam height measured again. Such a test can be used to simulate the initial foaming characteristics of the composition as well as the foaming characteristics at the time of use in which more dirt is incorporated from the surface being cleaned.

Testing for foaming properties is as follows:
1. Prepare a set of dry, clean graduated cylinders and water with a water hardness of 136.8 ppm (2.1 grains per liter) and a temperature of 25 ° C.
2. Add the appropriate amount of test composition to each cylinder and add water to bring the total composition + water in each cylinder to 500 mL.
3. Seal the cylinders and place them in the SCT.
4). Activate the SCT and rotate the cylinder for 2 minutes.
5. Within 1 minute, measure the foam height in centimeters.
6). The foaming property is the average height (in centimeters) of foam produced by the composition.

  The composition according to the invention preferably has a foaming property maximum of at least about 2 cm, more preferably at least about 3 cm, and even more preferably at least about 4 cm.

  The foam to weight ratio is a measure of the foam produced (ml) per gram of product. The ratio of foam to weight is measured as follows. Measure the weight of a volumetric instrument such as a graduated cylinder to obtain its own weight. The product is then dispensed into the graduated cylinder using a foam-generating dispenser where appropriate (a set number of strokes for a non-continuous dispenser device or a set time for a continuous dispenser device). The recommended duration is 10 strokes for non-continuous equipment (pump, nebulizer) and 10 seconds for continuous equipment. The dispensing rate during testing should be consistent with the dispensing rate during standard usage scenarios. For example, 120 strokes per minute for trigger sprayers or 45 strokes per minute for palm pumps.

The volume of foam produced is measured in ml using a volumetric instrument.
Weigh the volumetric instrument containing the dispensed product in grams. Subtract the weight of the volumetric instrument from this weight. The result is the grams of product dispensed. Finally, the foam to weight ratio (ml / g) is calculated by dividing the volume of foam produced (ml) by the weight of product dispensed (g).
The foam to weight ratio ml / g is easily converted to ml foam per ml product by multiplying the density of the highly viscous composition.

  Examples of the invention are illustrated by the following examples, which are not intended to limit the invention in any way. These examples are not to be construed as limiting the invention, as many variations thereof are possible without departing from the spirit and scope of the invention.

Example 1
The foam generation kit comprises a 300 ml hollow plastic container filled with a microemulsion dishwashing composition and a T1 series foamer from an attached Airspray similar to that shown in FIG. The T1 foamer is modified to include a third mesh at the nozzle tip as shown at 41 in FIG. A molding applicator according to FIG. 3 is also included. When dispensed, the foamed dishwashing composition has a foam to weight ratio greater than 3 ml / g, and the foam has a creamy, uniform appearance and feel. The foamed dishwashing composition is dispensed from the foam-generating dispenser into the pocket-type molding applicator by piercing the nozzle of the foam-generating dispenser into the mouth of the molding applicator and pressing down onto the activator. When used as described above, the dishwashing kit provides a good working distance and foam that lasts throughout standard use for washing dishes. However, if a foam-generating dispenser is not used (ie, the dishwashing composition is simply poured from the container), the effective foam dilution range does not clearly overlap the effective oil solubilization dilution range.

(Example 2)
An ionic microemulsion is provided and packed with the foam-generating dispenser of Example 1.

(Example 3)
A foam generation kit according to Example 1 is prepared except that the T1 foamer is modified to have a sponge at the tip instead of a third mesh. The sponge is an artificial sponge that is cut into a nozzle shape and securely fixed immediately inside the nozzle. The foam produced is creamy and aesthetically pleasing.
