Description

  The present invention relates to a foam generation kit.

  Compositions containing high concentrations of surfactants (high concentration surfactant compositions) such as concentrated dishwashing compositions, hand soap compositions, shampoo compositions, laundry compositions, polishing compositions, etc. are well known. Typically, it is provided in a liquid, gel or paste. 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 produce foams with low concentrations of surfactant composition (ie body wash containing> 12% surfactant), typically the interface This approach has not been successful for high concentration surfactant compositions to date, since there is a direct correlation between increased surfactant concentration and increased viscosity. In particular, the rheology of high concentration surfactant compositions 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 vessels, so the practical result is that formulators are able to meet the constraints of currently marketed foam-generating dispensers. It is often necessary to reduce the viscosity of This approach thus places an artificial physical limitation on the formulator's privilege to obtain the best performance and / or the lowest cost composition when foam generation is desired.

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

  The present invention relates to a foam generation kit comprising a non-aerosol container comprising a foam generation dispenser and preferably a high concentration surfactant composition present in the container. The high concentration surfactant composition contains at least about 20% by weight of the surfactant system of the high concentration surfactant composition. This foam-generating dispenser, when used with a high concentration surfactant composition, can generate foam having a foam (ie volume) to weight ratio of greater than about 2 mL / g.

  It has now been found that by combining a foam-generating dispenser and a highly concentrated surfactant composition, an acceptable foam can be formed simultaneously without undue physical effort and without using an aerosol propellant. While not intending to be limited by theory, it is believed that acceptable foam can be produced even with high concentration surfactant compositions when turbulent channels are gradually created.

  Furthermore, it is believed that a cleaning composition dispensed from a foam-generating dispenser according to the present invention can be better and / or faster cleaned than the same composition dispensed in another manner. While not intending to be limited by theory, it is believed that physical foam generation increases the total surface area of the high concentration surfactant composition. Since most washing interactions, such as the speed and completeness of oil emulsification, are directly related to the surface area to be covered, we believe that the form of the invention can significantly improve the overall washability. Furthermore, in the case of microemulsions and / or protomicroemulsions, surprisingly, by physically generating the foam, the present invention allows the physical to be achieved without chemically constraining the surfactant at the air-water interface. It has been found to achieve typical foam aesthetic benefits. Rather, even if foam is present, a greater percentage of the surfactant is more likely to be soiled, oily, etc. than if foam is formed by conventional methods such as mixing surfactant and water. It becomes chemically available for bonding.

  These and other features, aspects, advantages, and modifications of the present invention, as well as the embodiments described herein, will be apparent to those of ordinary skill in the art upon reading the present disclosure in conjunction with the appended claims. They are also encompassed within the scope of the claims.

(container)
Containers useful herein are non-aerosol containers and typically have a hollow body to hold a high concentration surfactant composition, preferably a dishwashing composition, as known in the art. Other materials may be used, but plastics, glasses and / or metals, preferably polymers or resins, such as polyethylene, polypropylene, polyethylene terephthalate, polycarbonate, polystyrene, ethyl vinyl alcohol, polyvinyl alcohol, thermoplastic elastomers, and these Most often bottles or cans formed from a mixture of 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. The foam-generating dispenser generates foam when activated 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 and easily refillable male and female members.

  The foam-generating dispenser can interact with the high concentration surfactant composition by any method for generating foam, for example, by chemical reaction, enzymatic reaction and / or mechanical action. However, as used herein, mechanical action is preferred, and typically gas, such as air, nitrogen, carbon dioxide, or the like is applied or mixed directly in a turbulent manner when dispensing the dishwashing composition. And the intended mechanism for physically forming the foam. 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 piston, pump, impingement surface, multiple meshes or nets, and / or atomizers that apply gas to form bubbles from air. In a highly preferred embodiment, the foam-generating dispenser uses at least 3, preferably 3-5 meshes, wherein the high concentration surfactant composition continuously moves these meshes to generate foam. To flow through. Without intending to be limited by theory, by continuously passing through the mesh, the highly concentrated surfactant composition is repeatedly turbulently mixed with air, thereby creating a foam generating effect using a single mesh. It is believed to increase several times over the case. As the percentage of surfactant system in the high concentration surfactant 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 activator, such as a pumping mechanism activated by a button and / or pressure. 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 about 3 ml to about 10 ml, more preferably 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, because this liquid then penetrates into the applicator (e.g. sponge), e.g. This is because, when used for cleaning, the use distance of the high concentration surfactant 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 into the cylinder 18 past the ball 16. 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 becomes finer and finer after passing through the second mesh 38 and the third mesh 41. It becomes uniform. These meshes may have the same or different pore sizes. Moreover, you may employ | adopt an additional mesh if desired.

  In a preferred embodiment, the foam-generating dispenser comprises a sponge mounted in or attached to the dispenser instead of or in addition to one or more meshes. The sponge also produces a foam when the high concentration surfactant composition is passed through its open cell structure by turbulence. Such a sponge may be provided inside the foam-generating dispenser and / or may be placed at the end of the nozzle if desired. While not intending to be limited by theory, additional meshes and / or sponges slightly inside and / or at the tip of the nozzle will act to generate bubbles immediately before dispensing, so It has been found to be particularly useful in the specification. As such, the user will see the desired foam as it passes through or just after the last turbulent region, but the quality of the foam is significantly degraded and / or before the quality has changed. Is the best.

FIG. 1 also shows a base cap 42 that secures the foam-generating dispenser to a container 44 that holds a high concentration surfactant composition.

  Solvents that can reduce product viscosity and / or impart shear thinning or non-Newtonian rheological properties to the composition, since such solvents are typically expensive and do not provide significant non-shear force related benefits. It may be present but is not preferred herein. Thus, in a preferred embodiment, the high concentration surfactant composition herein acts as a Newtonian fluid over the relevant shear force range during use in a foam-generating dispenser.

Further non-limiting examples of preferred enzymes are disclosed in WO 99/63034 A1 (Vinson et al., Published Dec. 9, 1999).

  Microemulsion or protomicroemulsion compositions, 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 water solubility of about 1 part to about 100 ppm per trillion. 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 compositions herein typically have an effective foam of less than about 50% of the dilution range, preferably from about 0% to about 40%, more preferably from about 0% to about 35%. Has a dilution range. 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 formation dilution range is calculated as follows: The soap foam generation curve of Graph I is obtained 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 with a foam-generating dispenser (i.e. dispensed from the dispenser), the effective foam is until a product concentration of about 3% is reached from the point of dispensing (100% product concentration). It is seen to be generated. 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, it overlaps the effective oil solubilization dilution range 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.

(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 to produce a foamy product for washing the next dish. It has been found that little dishwashing composition remains on the flat applicator. This increases the cost of using a foamed dishwashing composition because the distance of use of the composition is significantly reduced and is cumbersome because a new foamed dishwashing composition must always be applied on a flat applicator. is there. In contrast, a molded applicator that has a receiving area, such as a protective dimple and / or pocket for a 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 (The Dow Chemical Company (The Dow Chemical Company), published March 23, 1993); and Japanese Patent Publication No. 10-176073 (Bridgestone Company, June 30, 1998). It is described in the open).

  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 scraped off the molded applicator 12 rapidly. 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.

It is shown in 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 with a Brookfield viscometer model number LVDVII + at 20 ° C. 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, 0.1 g of food canola oil dyed with dye (available from Pylam Products, Tempe, Arizona, USA) is added and the vial is capped. The vial is shaken vigorously by hand for 5 seconds and placed until it becomes 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 of dye 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 by the density of the high concentration surfactant 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 includes a 300 mL hollow plastic container filled with the microemulsion dishwashing composition and a T1 series foam generator from an attached Airspray similar to that shown in FIG. The T1 foam generator comprises a third mesh at the tip of the nozzle at 41, as seen in FIG. A molding applicator according to FIG. 3 is also included. When dispensed, the foamed dishwashing composition has a foam to weight ratio of about 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)
The ionic microemulsions from the following Formulations A-G are provided packaged with the foam-generating dispenser of Example 1. Formulation F is a gel, but all other formulations are liquids.

(Example 3)
A foam generation kit is prepared according to Example 1 except that the T1 foam generator is changed to a sponge instead of a third mesh at the tip. The sponge is an artificial sponge cut into a specific shape and is firmly attached to the inside of the nozzle. The foam produced is aesthetically pleasing like a cream.
