Abstract

A foam-generating kit contains a non-aerosol container with a foam-generating dispenser and a high surfactant composition, preferably within the container. The high surfactant composition comprises, by weight of the high surfactant composition, at least 20% of a surfactant system and provides a 1% canola oil dissolution when tested at a 75% product concentration. When the foam-generating dispenser is employed with the high surfactant composition, the foam-generating dispenser generates a foam having a foam to weight ratio of greater than about 2 mL/g.

Description

Foam generator kit containing a dispenser that generates foam and a high composition viscosity.

Field of the Invention

The present invention relates to compositions and containers for them. In particular, the present invention refers to high viscosity compositions, especially to high viscosity cleaning compositions, and containers for the same. The present invention also relates to general to foam generating dispensers.

Background of the invention

High viscosity compositions, such as dishwashing compositions, washing compositions to hand with soap, hair conditioning compositions, fabric conditioning compositions, compositions for scrubbing, etc., are well known and are typically provided in the form of liquid, gel or paste. Although liquids and pastes they can be useful in different situations, these physical forms They are no longer considered novel or attractive. Also apart that it is desirable to provide new physical forms and interesting, the use of the previous compositions has been limited typically to apply or pre-apply these liquids, gels and pastes to a substrate by adding a additional stage of direct application thereof to the surface desired.

Although the use of a dispenser is known foam generator for foaming low viscosity compositions, This method has so far failed to succeed with high viscosity compositions. In particular, the rheology of high viscosity compositions makes it difficult to achieve a acceptable foam that has no flow characteristics extremely turbulent and violent. Since you are turbulent flow characteristics often require effort excessive physical or a very pressurized container, the result practical is that formulators must often reduce the viscosity of its products to meet the limitations of the foam dispensers currently marketed. Therefore, this method imposes an artificial physical limitation on the freedom of the formulator to achieve a better composition performance and / or lower cost.

Therefore, there is a need to have a foam generator dispenser that can produce foam from of a high viscosity composition. There is also the need to have a foam generator dispenser that can produce this foam without physical effort excessive and / or without using a propellant of aerosol.

Summary of the invention

The present invention relates to a kit foam generator containing a non-aerosol container with a foam generator dispenser and a composition in EMo / 22 high viscosity dishwashing microemulsion SE08, preferably inside the container. High composition viscosity has a viscosity of at least about 0.05 Pa.s. When the foam generator dispenser is used with the High viscosity composition, the foam generator dispenser generates a foam that has a relationship between foam (i.e. volume) and weight greater than about 2 ml / g.

It has now been discovered that the combination of a foam generator dispenser and a high composition viscosity can simultaneously provide a formation of acceptable foam without physical exertion excessive or use a spray propellant. Without pretending to impose no theory, it is believed that when a flow path occurs more and more turbulent can even prepare a composition high viscosity with a viscosity of at least about 0.050 Pa.s to produce an acceptable foam.

These and other elements, aspects, advantages and variations of the present invention and the described embodiments here will be apparent to the person skilled in the art. after reading the present description with the claims attached and that are within the scope of these claims.

Container

The container useful in the present invention is a non-aerosol container and typically has a body hollow to accommodate a high dishwashing composition viscosity and typically is a jar or canister formed of plastic, glass and / or metal, preferably of a polymer or resin such as polyethylene, polypropylene, polyethylene terephthalate, polycarbonate, polystyrene, ethyl vinyl alcohol, polyvinyl alcohol, thermoplastic elastomer, and combinations thereof, although others can also be used materials known in the art. These shape containers typical will contain from about 100 ml to about 2 l of liquid, preferably about 150 ml to about 1.2 l of liquid, and more preferably of about 200 ml to about 1 l of liquid, and they are fine known for containing liquid consumer products. These containers are widely marketed by many suppliers of containers.

Operationally attached to the container, directly or indirectly, there is a foam generator dispenser to generate a foam. When activated, the dispenser foam generator generates foam and at the same time dispenses the foamed composition from the container. The generator dispenser foam can be integrated into the container or separated from the same. If it is formed separately, the dispenser foam generator can be attached to the container by methods known in the art such as using a piece of transition, corresponding male and female threaded elements, pressurized and non-pressurized seals, locking parts and pressure closure and / or other methods known in the art. Preferably, the foam generating dispenser is attached to the container through a transition piece and / or with elements corresponding male and female threads that allow easy filled in.

The foam generator dispenser can interact with the high viscosity composition through any method of generating a foam, such as a reaction chemistry, an enzymatic reaction and / or a mechanical action. Without However, a mechanical action is preferred in the present invention. which typically involves a mechanism that transmits or mixes a gas, such as air, nitrogen, carbon dioxide, etc., directly to the dishwashing composition so turbulent during dispensing in order to physically train the foam. Preferably, the foam generator dispenser includes a mechanism that provides gas to form the foam to from the air through an air injector plunger, an opening foam generator, a shock surface, a mesh or net, a pump and / or a sprayer, more preferably, a plunger air injector, a pump, a shock surface, a plurality of meshes or nets and / or a sprayer that injects or provides air from the atmosphere to the wash composition of crockery In a very preferred embodiment, the dispenser foam generator uses at least three, preferably three to Five, meshes flowing the high viscosity composition through of these meshes in series to generate the foam. Without pretending impose any theory, it is believed that by flowing through the previous series meshes the high viscosity composition is repeatedly mixing turbulently with air, thus multiplying the foam generating effect reaching a level higher than Any mesh separately. As the viscosity of The high viscosity composition can be added meshes additional to provide the desired level of foam and / or foam quality

The foam generator dispenser also typically includes an activator, preferably an activator manual such as, for example, a trigger, a pumping mechanism pressure activated, a button and / or a slider, more preferably a button and / or a pumping mechanism activated by pressure that can be activated with a single finger. It is very preferred that the activator is designed so that a consumer can easily activate it even if your hands are wet and / or slippery, as in the middle of a dishwashing process manual. This trigger should allow the user to control easy and convenient way both the dispensing speed and The volume dispensed. For certain applications, as in the industry or in public facilities, others may be useful activators such as an electronic activator, an activator computer controlled, an electric viewfinder, a trigger infrared detection, a manual activated trigger with lever, etc. The foam generator dispenser useful herein invention generates a foam that has a relationship between foam and weight greater than about 2 ml / g, more preferably of about 3 ml / g to about 10 ml / g, and even more preferably from about 4 ml / g to about 8 ml / g. In addition, the foam generator dispenser useful herein invention generates at least about 2 ml, preferably of about 3 ml to about 10 ml and more preferably from about 4 ml to about 8 ml, foam per ml of dishwashing composition. "Creamy" foams and "soft" that have fine bubbles scattered so relatively uniform in them may be especially preferred for its aesthetic and / or performance characteristics. In certain cases are especially preferred foams that do not degrade significantly to liquid before 3 minutes. In particular, when the foam is dispensed on a clean surface of crystal (for example, a PYREX? plate) and allowed to stand there for 3 minutes at 25 ° C, less than 1 mm of liquid. Preferably, there should be no visible liquid on the edge of the foam after 3 minutes. However, in other cases it has also been discovered that a certain is also preferable amount of liquid (i.e. no foam) since after this liquid permeates the applicator (e.g., a sponge) and expands further The cleaning capacity of the high viscosity composition when used, for example, for cleaning dishes.

Fig. 1 is a sectional view of a preferred embodiment of the foam generator dispenser, 10, with a nozzle, 12, from which the foamed composition is dispensed of dishwashing. The dishwashing composition enters in the foam generator dispenser through a tube, 14, of immersion and flows through a ball, 16, to a cylinder, 18. A pin, 20, prevents the ball, 16, from escaping and also supports a spring, 22, coil and an inner rod, 24. A liquid plunger, 26, creates a suction that sucks the composition of dishwashing and makes it pass through the ball, 16 and the plug, 20, to a chamber, 28, of liquid and thus priming the dispenser, 10, foam generator. Meanwhile, a camera, 30, air and a piston, 31, air are also primed and when the activator, 32, is sunk, the chamber air, 30, air and the dishwashing composition of the chamber, 28, of liquid are forced turbulently into the chamber, 34, mixed and through a first mesh, 36 and a second mesh, 38, both held in place by a mesh support, 40. When the turbulent air mixture / dishwashing composition is forced through the first mesh, 36, a first is generated thick foam that becomes thinner and smoother after moving on to through the second mesh, 38, and the third mesh, 41. You are meshes can have the same or different pore size. Too Additional meshes may be used, if desired.

In a preferred embodiment, the dispenser foam generator contains a sponge in it or attached to the same, instead of or in addition to the one or more meshes. A sponge It also produces foam when the high viscosity composition is forced turbulently through its cell structure open This sponge may be contained inside the foam generator dispenser and / or can also be located in the end of the nozzle, as desired. Without pretending to impose No theory, it has been discovered that additional meshes and / or a sponge located slightly inside and / or at the tip of the nozzle are especially useful in the present invention, since which serve to generate the foam immediately before the dispensing Therefore, the user sees the desired foam when it is passes, or immediately after it passes, through the last turbulent flow zone, when the foam quality is maximum and before it is reduced significantly and / or otherwise change quality

Fig. 1 also shows a base plug, 42, fixing the foam dispenser to a container, 44, which contains The high viscosity composition.

Preferred foam generating dispensers useful in the present invention include: T8900, OpAd FO, 8203 and 7512 series foamers from Afa-Polytek-, Helmond, The Netherlands; T1, F2, and WR-F3 series foamers from Airspray International, Inc., Alkmaar, the Netherlands or North Pompano Beach, Florida, USA; TS-800 and Mixer series foamers from Saint-Gobain Calmar, Inc., City of Industry, California, USA; pump skimmers and tightening foams from Daiwa Can Company, Tokyo, Japan; TS1 and TS2 series foamers from Guala Dispensing USA., Inc., Hillsborough, New Jersey, USA; and skimmers of the YT-87L-FP, YT-87L-FX and YT-97 series from Yoshino Kogyosho Co., Ltd., Tokyo, Japan. See also the foam generating dispensers discussed in the Japanese publications Food & Package , (2001) vol. 42, No. 10, p. 609-13; Food & Package , (2001) vol. 42, No. 11, p. 676-79; and Food & Package , (2001) vol. 42, No. 12, p. 732-35. Variations and modifications of existing foam generating dispensers are especially useful in the present invention, especially when the volume ratio between air piston and product piston, mesh / net sizes, shock angle, etc., is modified. as well as when optimizing the sizes and dimensions of cylinders, rods, immersion tubes, nozzles, etc.

Although dispensers may be preferred trigger type foam generators for certain embodiments of the present invention, an activated pump is often preferred by finger and / or palm (see, for example, Fig. 1) by aesthetic reasons This is especially the case when the kit foam generator should not give the "rough" image typical of hard surface cleaners and cleaning products Intensive similar.

The solvent of the present invention preferably has a water solubility of at least about 12%, more preferably of at least approximately 50%, by weight of the solution.

Solvents may be present which are capable of reducing the viscosity of the product and / or transmitting a pseudoplastic or non-Newtonian rheology profile at compositions, although not preferred in the present invention since that these solvents are typically expensive and do not provide significant advantages related to the absence of shear. Therefore, in a preferred embodiment, the high composition viscosity of the present invention acts as a Newtonian fluid in the relevant shear interval during use in the foam generator dispenser.

Preferred solvents useful herein invention that convey a Newtonian behavior include monohydroxy alcohols, dihydroxy alcohols and polyhydroxy alcohols, ethers, and mixtures thereof. Alkyl carbonates such as Propylene carbonate are also preferred.

The enzyme useful in the present invention includes a cellulase, a hemicellulase, a peroxidase, a protease, a gluco-amylase, an amylase, a lipase, a cutinase, a pectinase, a xylanase, a reductase, an oxidase, a phenoloxidase, a lipoxygenase, a ligninase, a pululanase, a tanasa, a pentosanasa, a malanasa, a β-glucanase, an arabinosidase and a mixture of the same.

An enzyme is typically present at about 0.0001% at approximately 5% active enzyme, by weight. Enzymes Preferred proteolytics are selected from the group consisting of ALCALASE® (Novo Industri A / S), BPN ', Protease A and Protease B (Genencor), and mixtures thereof. Protease B is more preferred. Preferred amylase enzymes include TERMAMYL®, DURAMYL® and the amylase enzymes described in WO 94/18314 A1, Antrim et al., published on August 18, 1994 (granted to Genencor International) and WO 94/02597 A1, Svendsen and Bisg \ ring {a} rd-Frantzen, published on February 3 1994 (granted to Novo Nordisk A / S). Other examples no Preferred enzyme limits are described in WO 99/63034 A1, Vinson et al., Published December 9, 1999.

A dishwashing composition in EMo / 22SE08 microemulsion typically also contains an oil poorly soluble in water that has a water solubility of less than 5,000 ppm, preferably 0 ppm (parts per million) to 1,500 ppm, by weight of oil poorly soluble in water, and more preferably from about 1 part per trillion to about 100 ppm. Preferred low water soluble oils useful herein invention include terpenes, isoparaffins, other oils that have the above solubility, and a mixture thereof.

In the absence of a dispenser generating foam, the dishwashing composition of the present invention typically has a foam dilution range effective of less than about 50%, preferably of about 0% to about 40% and more preferably of about 0% to about 35%, of the range of dilution. However, in an embodiment of the present invention, the dishwashing composition, when used with the foam generator dispenser, has a dilution interval of effective foam of at least about 50%, preferably of about 50% to about 100%, more preferably of about 75% to about 100%, and even more preferably from about 85% to about 100%, of dilution interval The effective foam dilution range is Calculates as follows: The generation curves of soaps from graph I are represented by analyzing different dilutions of a dishwashing composition by means of cylinder soaps test herein. This curve can be generated with or without dispensing from a dispenser  foam generator to the cylinders. The expression "foam effective "is defined herein as the foam that It has at least half (50%) of the maximum foam volume generated for a certain dishwashing composition according to the Soap generation curve. Therefore, in graph I, when the foam generator dispenser is not used, the foam effective is formed from a product concentration of approximately 28% to approximately 2%, which translates into a effective foam dilution range of 26% (i.e. 28% -2%). However, when used (ie dispensed) it dishwashing composition with the dispenser generating foam, it can be seen that the effective foam is generated from the dispensing point (100% product concentration) up to achieve a product concentration of approximately 3%. This it is because the dishwashing kit generates foam at a dilution of dishwashing composition: water basically different from the dilution at which the maximum volume of foam according to the cylinder soaps test. Therefore the effective foam dilution interval when dispensing the dishwashing composition from a foam dispenser (graph I) is 97% (that is, 100% -3%).

one

The dishwashing composition useful in The present invention has an oil dissolution curve obtained by the oil dissolution test defined in the present memory The expression "effective oil dissolution" defined herein as a solution of al oil minus 20% of the maximum amount of dissolved oil for a certain composition for dishwashing according to the curve of oil solution represented as a function of the concentration of product (ie dilution). Therefore, in graph I, the maximum amount of dissolved oil is approximately 4.7 to one product concentration of 70% and, consequently, the effective oil solution is an amount of at least approximately 0.94. The effective oil solution occurs in dilution ranges from about 96% to about 42%, which translates into a dilution dilution interval of Effective oil of approximately 54%.

As can be seen in graph I, there is no practically overlap between the generation curve of soaps without a foam generator dispenser and the interval of dilution of effective oil solution. Similarly, you can Note that if there is no foam dispenser, no there is overlap between the effective foam dilution interval (28% to 2%) and the dilution range of oil dissolution effective (from 42% to 96%). On the contrary, when using a foam generator dispenser, foam dilution interval effective (3% to 100%) overlaps completely (100%) with all the dilution range of effective oil solution (from 42% to 96%) In a preferred embodiment, the dilution range of Effective foam overlaps with the dilution dilution interval of effective oil, preferably the dilution range of Effective foam overlaps with the dilution dilution interval of oil effective at least about 10%, more preferably in about 25% to about 100%, and even more preferably in about 50% at approximately 100%, especially in the case of a microemulsion or a protomicroemulsion. In addition, it is very preferred that the interval Effective foam dilution overlaps with the point on the curve of oil solution where the oil solution is maximum. By therefore, the present invention encourages the user to use the product at a concentration / dilution of product that dissolves from oil more effectively, thus optimizing cleanliness.

The present invention has recognized that you are EMo / 22SE08 microemulsion dishwashing compositions require that the container and the foam generator dispenser the present invention achieve acceptable foaming for the consumer at a dilution in which the dissolution curve of oil is more efficient and preferably maximum. Therefore, it prefers that when the dishwashing composition is used with the container and the foam generator dispenser, it generate an effective foam at a dilution factor significantly different from the soap generation curve when not use the container and the foam dispenser.

The dishwashing hand composition, the cleaning compositions, protomicroemulsion compositions and the microemulsion compositions useful in the present invention are known in the art, as described in, for example, WO 96/01305 A1, Farnworth and Martin, published on January 18, 1996; 5,854,187, issued to Blum et al. on December 29, 1998; US 6,147,047, granted to Robbins et al. on 14 of November 2000; WO 99/58631 A1, Robbins et al., Published 18 November 1999; US 4,511,488, granted to Matta on April 16, 1985; US 5,075,026, granted to Loth et al. on December 24, 1991; US 5,076,954, granted to Loth et al. on 31 of December 1991; US-US05082584, granted to Loth and cabbage. on January 21, 1992; US 5,108,643, granted to Loth et al. on April 28, 1992; codependent patent application US-60/451064 (P&G case # AA614FP), Ford and col., entitled "Protomicroemulsion, Cleaning Implement Containing Same, And Method Of Use Therefor, "filed February 28 of 2003; codependent patent application US-60/472941 (P&G case # AA614P2), Ford and col., entitled "Protomicroemulsion, Cleaning Implement Containing Same, And Method Of Use Therefor, "filed May 23, 2003; codependent patent application US -____________ (P&G case # AA614P3), Ford and col., entitled "Protomicroemulsion, Cleaning Implement Containing Same, And Method Of Use Therefor ", filed on_________; and US -___________ codependent patent application (P&G case # AA633FP), Hutton and Foley, titled "Protomicroemulsion, Cleaning Implement Containing Same, And Method Of Use Therefor ", filed on _________. dishwashing compositions mentioned in the above references or variations of the above compositions are especially preferred for use together with the container and the foam generator dispenser described herein memory.

Although the high viscosity composition is preferably marketed inside the container forming a only article, this is not necessary since in the present invention contemplated recharges and separate components within the same kit

Shaped Applicator

It has also been discovered that an applicator shaped can surprisingly provide results and an ease of use significantly better than those of a normal applicator The shaped applicator is designed and sized to be easily kept in hand and used to apply the foamed dishwashing composition to the surface to be cleaned, that is, the plate. It has been observed that if the foamed dishwashing composition is applied to a flat applicator, then the foamed wash composition of dinnerware will spread quickly over the first contacted dish but there will be little foamed dishwashing composition in the flat applicator to clean the following dishes. This makes the  use of a foamed dishwashing composition is expensive, since the cleaning ability of the composition looks significantly reduced, and it is also heavy since it is it is necessary to constantly apply new foamed composition of dishwashing in the flat applicator. On the contrary, a shaped applicator containing a reception area, such as a protected indentation and / or a pocket, for the composition Foamed dishwashing, will contain and dose more Effective foamed dishwashing composition along the weather.

Since the shaped applicator is often will use to rub, it is preferable that at least one surface thereof contains an abrasive surface. The shaped applicator is typically selected from a porous material such as a natural or artificial sponge, a brush, an abrasive device metallic, a woven material, a nonwoven material, a material abrasive, a plastic material, a cloth material, a material microfiber cleaner, a polymeric material, a material resin, a rubber material, or a mixture thereof, preferably a natural or artificial sponge, a brush, a metallic abrasive device, an abrasive material, a material of Foamed rubber, a functional absorbent material (FAM), a foam of polyurethane, and a mixture thereof, and more preferably a natural or artificial sponge, a brush, an abrasive material, a foamed rubber material, and a mixture thereof, being highly preferred all types of open cell structures. These shaped applicators are marketed by different suppliers, such as Minnesota Mining and Manufacturing Company (3M), St. Paul, Minnesota, USA If the shaped applicator is made of a relatively delicate material or a material easily tear, then it is preferable that this material is covered, totally or partially, with a material permeable to water, more robust, such as a nonwoven material. They are also useful surfaces formed from plastic materials or Polymers such as those marketed, for example, by Minnesota Mining and Manufacturing Company (3M), St. Paul, Minnesota, USA, and found, for example, in the use scourers universal Scotch-Brite ™.

Preferably, the FAMs useful herein invention have an absorbent capacity of more than about 20 g H2O / g, more preferably 40 g H2O / g, by weight of FAM. A FAM of this preferred type is described in US 5,260,345, issued to DesMarais et al. the 9 of November 1993, or US-5,889,893, granted to Dyer et al. on May 4, 1999. Examples of a preferred polyurethane are described in US 5,089,534, issued to Thoen et al. on February 18, 1992; US 4,789,690, granted to Milovanovic-Lerik et al. on December 6, 1988; JP 10-182780, Kao Corporation, published on 7 July 1998; JP-9-30215, Yokohama Gum, published on February 4, 1997; JP- 5-70544, The Dow Chemical Company, published on 23 March 1993; and JP- 10-176073, The Bridgestone Company, published June 30, 1998.

Preferably, the shaped applicator is not hard but has at least one resilient part, preferably a resilient part that is covered by an abrasive surface. This optional resilient part allows the user to modify the amount of contact, pressure, etc., between the rubbing surface And the plate. The foamed dishwashing composition is, by both, preferably applied in or on the shaped applicator directly from the foam generator dispenser.

Returning to Fig. 2, which shows a view of upper perspective cutting of a preferred embodiment of the shaped applicator, 12, of the present invention, an applicator shaped sponge, 12, contains a reception area, 50, a which is applied the foamed dishwashing composition for its use. The reception area, 50, is therefore limited in a way typical for a wall, 52, which prevents the foamed composition from being quickly removed by rubbing of the shaped applicator, 12. The reception area is preferably a concave indentation in the shaped applicator that can have any shape and design that allow to maintain the foamed dishwashing composition in contact with the shaped applicator. In a preferred embodiment, the reception area contains a relatively concave wall inclined or other structure that effectively maintains the foam detergent in the reception area and dispense it during the typical use. Typically, the reception area contains about 1 ml to about 200 ml, preferably of about 2 ml to about 150 ml and more preferably from about 5 ml to about 100 ml, of composition Foamed dishwashing.

In Fig. 2, the shaped applicator, 12, it also contains a plurality of abrasive surfaces, 54, for rub a plate. It is very preferred that at least one is found abrasive surface in the shaped applicator.

Fig. 3 shows a sectional view in perspective of a preferred embodiment of the shaped applicator, 12, which is shaped as a sponge applicator, 12, with a pocket reception area, 50, whose internal dimensions They are indicated by dashed lines. The composition Foamed dishwashing is added to the reception area, 50, through a mouth, 56, which may be permanently open or It can be closed as desired. An abrasive surface, 54, basically covers the entire exterior of the shaped applicator, 12, to help remove stains from a plate.

Soaps profile can be measured using a soapy cylinder analyzer (SCT) and using the data to represent a generation curve of suds. The SCT has a set of 4 cylinders. Each cylinder It is typically 30 cm long and 10 cm in diameter. The Cylinder walls are 0.5 cm thick and the bottom of the Cylinders is 1 cm thick. The SCT spins a solution problem in a closed cylinder, typically a plurality of transparent plastic cylinders, at a speed of approximately 21 revolutions per minute, for 2 minutes, after measuring the height of the soaps. Then you can add dirt to the test solution, stir again and return to measure the height of the resulting soaps. This essay can be used to simulate the initial soap profile of a composition, as well as its profile of soaps during use when more dirt is introduced from the surface that is washed

The soap profile test is performed as follows:

one.

Prepare a set of cylinders clean, dry and calibrated, and water with a hardness of 136.8 parts per million (2.1 grains per liter), and with a temperature of 25 ° C

2.

Add the appropriate amount of problem composition to each cylinder and add water to prepare in total 500 ml of composition + water in each cylinder.

3.

Seal the cylinders and place them in the SCT.

Four.

Put on Start the SCT and rotate the cylinders for 2 minutes.

5.

To the After 1 minute, measure the height of the soaps in centimeters.

6.

He Soaping profile is the average level of soaps, in cm, generated by the composition.

The compositions according to the invention preferably they have a maximum soap profile of at least about 2 cm, more preferably at least about 3 cm, and even more preferably of about 4 cm

The relationship between foam and weight is a measurement of the ml of foam generated per gram of product. The relationship between foam and weight is measured as follows: volumetric measuring device, such as a test tube, to obtain A tare weight. The product is then dispensed, using the foam generator dispenser, if applicable, to a test tube for a fixed number of activations for the devices Discontinuous dispensers or for a fixed time for continuous dispensing devices. The suggested duration is 10 activations for discontinuous devices (pumps, sprayers) or 10 seconds for continuous devices. The speed of dispensing in the trial should be consistent with the speed of dispensing in normal use scenarios. For example, 120 activations per minute for sprayers with trigger or 45 activations per minute for palm pumps.

The volume of foam generated is measured in ml using the volumetric measuring device.

The volumetric measuring device that contains The product dispensed is weighed in grams. Subtract from this weight the tare of the volumetric measuring device. The result is the grams of product dispensed. Finally, the relationship is calculated between foam and weight, in ml / g, dividing the volume of foam generated (in ml) between the weight of the product dispensed (in g).

The ratio between foam and weight in ml / g is easily converted to ml of foam per ml of product multiplying by the density of the composition of high viscosity.

They are presented below for illustrative purposes. examples of the invention that are not intended to be in any way Limitations of it. The examples should not be considered as limitations of the present invention since it is possible to realize many variations thereof without abandoning the spirit or the scope of the invention.

Example one

A foam generator kit contains a 300 ml hollow plastic container filled with a composition of dishwashing in microemulsion and a T1 series frother Airspray connected, similar to that shown in Fig. 1. The frother T1 is modified to include a third mesh, as noted in Fig. 1, at 41, at the tip of the nozzle. An applicator shaped according to Fig. 3 is also included. When dispenses, the foamed dishwashing composition has a ratio between foam and weight of approximately 3 ml / g, and the foam It has a creamy and soft touch. The foamed wash composition of dishes is dispensed from the foam dispenser to a pocket-shaped applicator sticking the dispenser nozzle foam generator at the mouth of the shaped and pressing applicator the activator When used as described above, the dishwashing kit provides good cleaning capacity and a foam that lasts all normal use of dish cleaning. Without However, if the foam generator dispenser is not used (it is that is, the dishwashing composition is simply poured from the container), the effective foam dilution interval does not significantly overlaps with the dilution interval of effective oil solution.

Example 2

A packaged ionic microemulsion is provided. with the foam generator dispenser of example 1.

Example 3

A foam generator kit is prepared according to the Example 1, except that the T1 frother is modified by placing a sponge on the tip, instead of a third mesh. The sponge is an artificial sponge that is cut to shape and fixed safely right inside the nozzle. The foam generated is Creamy and aesthetically pleasing.
