Description

Foam-generating kit containing a foam-generating dispenser and a high viscosity composition

The present invention relates to a composition and a container therefor. In particular, the present invention relates to high viscosity compositions, in particular high viscosity cleaning compositions, and containers for the same. The invention also generally relates to a foaming dispenser.

High viscosity compositions such as dish washing compositions, hand soap compositions, hair conditioner compositions, fabric conditioner compositions, scrubbing compositions and the like are well known and they are generally provided in liquids, gels or pastes. Although liquids and pastes may be useful in a variety of situations, such physical forms are no longer considered new and exciting. In addition, the provision of new and interesting physical forms is preferred, but the use of such compositions has generally been limited to the further steps of applying or preliminary application of such liquids, gels and pastes into the substrate, and then directly to the desired surface.

It is known to foam low viscosity compositions using a foaming dispenser, but this approach has not been successful to date for high viscosity compositions. Specifically, the rheology of the high viscosity composition makes it difficult to achieve satisfactory foam without extremely intense turbulent flow characteristics. Such turbulent flow characteristics often require excessive physical effort or highly pressurized containers, and as a result it is often necessary for the formulator to lower the viscosity of the product to actually match the limits of currently available foaming dispensers. Thus, this approach imposes artificial physical constraints on the formulator freely achieving the best performance and / or lowest cost composition.

Therefore, there is a need for a foaming dispenser capable of producing bubbles from high viscosity compositions. There is also a need for a foaming dispenser that may produce such bubbles without the need for excessive physical effort and / or the use of aerosol propellants.

Summary of the Invention

The present invention relates to a non-aerosol container with a foaming dispenser and a high viscosity composition, preferably a foaming kit comprising a high viscosity composition in the container. The viscosity of the high viscosity composition is at least about 0.05 Pa · s. When the foaming dispenser is used in conjunction with a high viscosity composition, the foaming dispenser generates foam having a foam (ie, volume) to weight ratio greater than about 2 mL / g.

It has now been found that the combination of foaming dispenser and high viscosity composition can simultaneously provide satisfactory foaming properties without excessive physical effort and without the use of aerosol propellants. Without being bound by theory, it is contemplated that even higher viscosity compositions with viscosities of about 0.050 Pa.s or more can be made to produce satisfactory foams when an increasingly turbulent turbulent path is created.

Vessel

Containers useful in the present invention are non-aerosol containers and generally have a hollow body for holding high viscosity compositions, preferably dishwashing compositions, and generally plastics, glass, although other materials known in the art may also be used. And / or bottles formed from metals, preferably polymers or resins, such as polyethylene, polypropylene, polyethylene terephthalate, polycarbonate, polystyrene, ethyl vinyl alcohol, polyvinyl alcohol, thermoplastic elastomers or combinations thereof Or canister. Such containers will generally contain from about 100 mL to about 2 L of liquid, preferably from about 150 mL to about 1.2 L of liquid, more preferably from about 200 mL to about 1 L of liquid, for holding consumer liquid products. It is well known. Such containers are widely available from many container suppliers.

A foaming dispenser for generating foam is operatively attached to this container directly or indirectly. When this foaming dispenser is operated, it generates bubbles and at the same time dispenses the foamed composition from the container. The foaming dispenser may be formed integrally or separately with the container. The foaming dispenser, when individually formed, may be, for example, by methods known in the art, for example, transition pieces, corresponding threaded male and female members, pressurized and non-pressurized seals, lockable and It may also be attached to the container using snap-on parts, and / or other methods known in the art. Preferably, the foaming dispenser is attached to the container via a transition piece to facilitate easy refilling and / or using a corresponding threaded male and female member.

The foaming dispenser may interact with the high viscosity composition to generate the foam through any method such as chemical reaction, enzymatic reaction and / or mechanical action. However, in the present invention, a mechanical action is preferred, which generally requires a mechanism for distributing or mixing the gas, such as air, nitrogen, carbon dioxide, etc., directly into the dishwashing composition in turbulent flow upon distribution to physically form the foam. do. Preferably, the foaming dispenser comprises air for injecting or delivering air to the dishwashing composition, for example, a piston for injecting air, foaming openings, impingement surfaces, meshes or nets, pumps and / or sprayers, and more preferably air from the atmosphere. A gas delivery mechanism for forming bubbles from the air through the injection piston, pump, impingement surface, a plurality of meshes or nets and / or nebulizers. In a very preferred embodiment, the foaming dispenser uses at least three, preferably three to five meshes, in which case the high viscosity composition flows through these continuous meshes for foaming. Without wishing to be bound by theory, the present high viscosity composition is repeatedly mixed with air in turbulent flow by the continuous flow through the mesh, thereby doubling the foaming effect beyond any foaming effect of any single mesh. As the viscosity of this high viscosity composition increases, additional mesh may be added to provide the desired level of foaming properties and / or quality.

This foaming atomizer is also generally an actuator, preferably a manual actuator, for example a trigger, a pressurized pumping mechanism, a button and / or a slider, more preferably a button which can be operated with one finger. And / or a pressure actuated pumping mechanism. It is highly desirable that the actuator be designed to facilitate operation when the hand is wet and / or slippery, such as during a consumer dishwashing by hand. Such actuators should allow the user to easily and conveniently control both the dispensing speed and the volume dispensed. In certain applications, for example in industrial or public facilities, other actuators, for example electronic actuators, computer controlled actuators, electric eye or infrared detection actuators, manual lever assisted actuators, etc. May be useful. The foaming dispensers useful in the present invention are foamed foams having a foam to weight ratio greater than about 2 mL / g, more preferably from about 3 mL / g to about 10 mL / g, even more preferably from about 4 mL / g to about 8 mL / g. Generate. In addition, the foaming dispenser useful in the present invention generates at least about 2 mL of foam, preferably from about 3 mL to about 10 mL of foam, more preferably from about 4 mL to about 8 mL of foam, per mL of dishwashing composition. “Rich” and “soft” bubbles with fine bubbles dispersed relatively evenly throughout may be particularly desirable for aesthetic and / or performance features. In certain cases, preferred foams that do not significantly degrade into liquid over a period of 3 minutes are particularly preferred. Specifically, less than 1 mm of liquid should be visible when the foam is dispensed onto a clean glass surface (eg, PYREX ™ plate) and left at 25 ° C. for 3 minutes. Preferably, no liquid is visible at the edge of the foam after 3 minutes. In other cases, however, it has also been found that a certain amount of liquid (ie, non-foam) is also preferred, which when this liquid subsequently penetrates into the applicator (eg a sponge) and is used for cleaning dishware, for example. This is because it further extends the mileage of the high viscosity composition.

1 is a cutaway view of a preferred embodiment of a foaming dispenser 10 that includes a nozzle 12 through which a foamed dishwashing composition is dispensed. The dishwashing composition enters the foaming dispenser through a dip tube 14 and flows through the ball 16 into the cylinder 18. The plug 20 prevents the ball 16 from coming off and also supports the coil spring 22 and the inner rod 24. The liquid piston 26 draws the dishwashing composition past the ball 16 and plug 20 and into the liquid chamber 28 to generate a suction force that prepares the foaming dispenser 10 to operate. On the other hand, the air chamber 30 and the air piston 31 are also ready for operation, and both the air from the air chamber 30 and the dishwashing composition from the liquid chamber 28 when the actuator 32 is depressed Turbulently pushed into the mixing chamber 34 and then through the first mesh 36 and the second mesh 38, both held in place by the mesh holder 40. The first coarse foam is generated as the mixture of turbulent air / dishwashing composition passes through the first mesh 36, which becomes finer and more even after passing through the second mesh 38 and the third mesh 41. . These meshes may have the same or different pore sizes. In addition, additional meshes may also be used if desired.

In a preferred embodiment, the foaming dispenser comprises a sponge in or attached to, instead of or in addition to one or more meshes. The sponge also creates bubbles as the high viscosity composition is turbulently pushed through the open cell structure of the sponge. Such a sponge may be included inside the foaming dispenser and / or located at the end of the nozzle if desired. Without wishing to be bound by theory, it has been found that further meshes and / or sponges located at the tip of the nozzle and / or slightly inside the nozzle are particularly useful in the present invention, which serve to generate bubbles immediately before dispensing. Because. Thus, the user sees the desired foam as the foam passes through the last turbulent region, or immediately after, while the foam quality is superb and before the foam is significantly weakened and / or otherwise the quality is changed.

1 also shows a base cap 42 that secures a foaming dispenser to a container 44 holding a high viscosity composition.

In particular, by changing the volume ratio, mesh / net size, collision angle, etc. of the pistons for air-to-product pistons and optimizing the size and dimensions of cylinders, rods, dip tubes, nozzles, etc. Modifications are particularly useful in the present invention.

In certain embodiments of the present invention, triggered foaming dispensers may be preferred, but pumps of the type operated by fingers and / or palms (eg, see FIG. 1) are often preferred for aesthetic reasons. . This is especially true when the foaming kit is distinguished from typical hard surface cleaners and similar heavy-duty products of "harsh images".

The water solubility of the solvents of the present invention is preferably at least about 12%, more preferably at least about 50% by weight of the solution.

There may be solvents that reduce the viscosity of the product and / or give the composition a shear thinning or non-Newtonian rheology profile, but this is not desirable in the present invention, which is generally expensive and significant non- It does not provide any shear-related effects. Therefore, in a preferred embodiment, the high viscosity compositions of the present invention act as Newtonian fluids throughout the range of shear forces involved during use in a foaming dispenser.

Newton's behavior and solvents useful and preferred in the present invention include mono, di and poly hydroxy alcohols, ethers and mixtures thereof. Alkyl carbonates such as propylene carbonate are also preferred.

Further non-limiting examples of preferred enzymes are disclosed in Vinson WO 99/63034 A1, published December 9, 1999.

Microemulsions or raw microemulsion-like compositions, especially dishwashing compositions, also generally contain low water soluble oils, the water solubility of which is less than about 5,000 ppm, preferably from about 0 ppm to about 1,500, based on the weight of the low water soluble oil. ppm, more preferably from about 1 part per trillion to about 100 ppm. Low water soluble oils useful and preferred for the present invention include terpenes, isoparaffins, other oils having such solubility, and mixtures thereof.

In the absence of a foaming dispenser, the effective foaming dilution range of the dishwashing compositions of the present invention is less than about 50% of the dilution range, preferably from about 0% to about 40%, more preferably from about 0% to about 35%. However, in embodiments of the present invention, the effective foaming dilution range of the dishwashing composition when used with the foaming dispenser is at least about 50% of the dilution range, preferably from about 50% to about 100 %, More preferably about 75% to about 100%, even more preferably about 85% to about 100%. The effective foam production dilution range is calculated as follows: The foam generation curve of Graph I is generated by testing variously diluted dishwashing compositions through the foam cylinder test herein. Such curves can be generated with or without dispensing from the foaming dispenser into the cylinder. In the present invention, "effective foam" is defined as a foam that is at least half (50%) of the maximum volume of foam produced for a given dishwashing composition according to the foam generation curve. Thus, in Graph I when no foaming dispenser is used, the effective foam is formed at a product concentration of about 28% to about 2%, which produces 26% (ie 28%-2%) of effective foam. Switch to dilution range. However, when the same dishwashing composition is used with a foaming dispenser (i.e., dispensed from a foaming dispenser), effective foam is produced from the time of dispensing until the concentration of the product reaches about 3% (100). Product concentration). This is because the dishwashing kit generates bubbles at dilution levels of water that are substantially different than the dilution level at which the maximum volume of foam is formed according to the foam cylinder test. Thus, in the graph I, the effective foam generation dilution range when the dishwashing composition is dispensed from a foaming dispenser is 97% (ie 100%-3%).

Graph I

Dishwasher compositions useful in the present invention have an oil solubility curve produced by the oil solubilization test as defined herein. "Effective oil solubility" is defined herein as oil solubility that is at least 20% of the maximum amount of oil that becomes soluble for a given dishwashing composition according to an oil solubility curve plotted as a function of product concentration (ie, dilution level). Thus, in Graph I, the maximum amount of oil to be soluble is about 4.7 at a product concentration of 70%, so the effective oil solubility is an amount of at least about 0.94. Effective oil solubility occurs in a dilution range of about 96% to about 42%, which translates into an effective oil solubilization dilution range of about 54%.

As can be seen in Graph I, there is virtually no overlap between the foam generation curve without the foaming distributor and the effective oil solubilization dilution range. Similarly, in the absence of a foaming dispenser, it can be seen that there is no overlap between the effective foaming dilution range (28% to 2%) and the effective oil solubilizing dilution range (42% to 96%). In contrast, when a foaming dispenser is used, the effective foaming dilution range (3% to 100%) overlaps completely (100%) with the entire effective oil solubilizing dilution range (42% to 96%). In a preferred embodiment, particularly for microemulsions or raw microemulsions, the effective foaming dilution range overlaps with the effective oil solubilization dilution range, preferably the effective foaming dilution range is at least about 10% of the effective oil solubilization dilution range. , More preferably about 25% to about 100%, even more preferably about 50% to about 100%. It is also highly desirable that the effective foaming dilution ranges overlap at the point of the oil solubility curve with the highest oil solubility. Thus, the present invention facilitates the user to use the product at a concentration / product dilution level that solubilizes the oil more effectively, thereby optimizing the cleaning.

In the present invention, such dishwashing compositions, in particular microemulsion and one-microemulsion-type dishwashing compositions, are intended to achieve foaming properties that are satisfactory to consumers at dilution levels where the oil solubility curve is more effective and preferably maximized. It is recognized that a foaming dispenser and a container are required. Therefore, when the dishwashing composition is used with a container and a foaming dispenser, it is preferable that the effective foam is generated at a dilution factor significantly different from the foam generation curve when the container and the foaming dispenser are not used.

Foam is produced when the high viscosity composition is dispensed from a foaming dispenser.

This high viscosity composition is preferably sold in a container as a single item, but this is not necessary for refill products and the individual components in the same kit are contemplated in the present invention.

Molding applicator

It has also been surprisingly found that molding applicators can provide significantly improved results and ease of use compared to ordinary applicators. The molding applicator is designed and sized to be easily held in the hand and is used to apply a foamed dish washing composition to the surface to be cleaned, ie the dish. When the foamed dishwashing composition is applied to a flat applicator, the foamed dishwashing composition is quickly applied onto the first dish contacted, but the foamed dishwashing composition is hardly left on the flat applicator for subsequent dishware cleaning. It turned out that it would not. This makes using foamed dishwashing compositions cumbersome because the composition mileage is significantly reduced and expensive and the newly foamed dishwashing compositions need to be constantly applied to a flat applicator. In contrast, molding applicators comprising a receiving area for a foamed dishwashing composition, such as a protected indentation and / or pocket, more effectively retain and foam the dishwashing composition over time. Will be assigned.

Since the molding applicator will often be used for scrubbing purposes, it is desirable for at least one surface to comprise an abrasive surface. Molding applicators are generally porous materials such as natural or artificial sponges, brushes, metal scouring devices, woven materials, nonwoven materials, abrasive materials, plastic materials, cloth materials, microfiber cleaning materials, polymeric materials, Resin materials, rubber materials or mixtures thereof, preferably natural or artificial sponges, brushes, metal scouring devices, abrasive materials, foamed rubber materials, functional absorbent materials (FAM), polyurethane foams and their Mixtures, more preferably natural or artificial sponges, brushes, abrasive materials, foamed rubber materials and mixtures thereof, all types of open cell structures being very preferred. Such molding applicators are available from a variety of sources, such as Minnesota Mining and Manufacturing Company (3M), St. Paul, Minn., USA. If the forming applicator is formed of a relatively delicate material, or a material that is easily torn, it is preferred that the material is partially or completely covered with a water-permeable, more durable material, for example a nonwoven material. Also useful are, for example, those found on Scotch-Brite ™ General Purpose Scrubbing Pads and available from the Minnesota Mining and Manufacturing Company (3M), St. Paul, Minn. A surface formed of a plastic or polymeric material.

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

Preferably, the molding applicator is not rigid and instead has one or more elastic parts, preferably elastic parts covered by a polishing surface. This optional resilient portion allows the user to vary the amount of contact, pressure, etc., between the surface being scrubbed and the dish. Thus, a foamed dishwashing composition is preferably applied directly into or onto the molding applicator from a foaming dispenser.

Returning to FIG. 2, which shows a cut-away top perspective view of a preferred embodiment of the molding applicator 12 of the present invention, the sponge-shaped molding applicator 12 includes a receiving area 50 to which a foamed dish washing composition is applied for use. ). Thus, the receiving area 50 is generally defined by walls 52 that protect the foamed composition from being quickly rubbed off from the molding applicator 12. The receiving area is preferably an indentation in the shaping applicator that can have any shape and design that keeps the foamed dishwashing composition in constant contact with the shaping applicator. In a preferred embodiment, the receiving area comprises a relatively steep, concave wall or other structure that effectively retains the foamed detergent in the receiving area and distributes the detergent over time during typical use. Generally, the receiving zone has a foamed dishwashing composition of about 1 mL to about 200 mL, preferably about 2 mL to about 150 mL, more preferably about 5 mL to about 100 mL.

In FIG. 2, the forming applicator 12 further includes a plurality of polishing surfaces 54 for scrubbing the dishes. It is highly desirable that at least one abrasive surface be provided on the forming applicator.

FIG. 3 shows a cutaway perspective view of a preferred embodiment of a forming applicator 12 formed of a sponge shaped applicator 12 having a pocket-shaped receiving region 50 with dotted internal dimensions. The foamed dishwashing composition is added to the receiving area 50 through a mouth 56 which may be permanently open or closed if necessary. The abrasive surface 54 substantially covers the entire exterior of the molding applicator 12 to help remove stains from the dishes.

Test Methods

Viscosity in the present invention is measured at 20 ° C. on Brookfield Viscometer Model # LVDVII +. The spindle used for the measurement is 12 rpm having a speed suitable for measuring products of various viscosities, for example for the measurement of products with viscosities greater than 1 Pa.s; 3 rad / s (30 rpm) for the measurement of products having a viscosity between 0.5 Pa.s-1 Pa.s; For measurement of products with a viscosity of less than 0.5 Pa · s, the S31 spindle is 6 rad / s (60 rpm).

To determine the solubilization capacity, 10.0 g of product to be tested (this amount contains water when tested at specific dilution levels) are placed in a 25 mL scintillation vial. 0.045% of Pylakrome RED-a mixture of LX1903 (SOLVENT Red 24 CAS # 85-83-6 and Solvent Red 26 CAS # 4477-79-6, Pylam Products, Tempe, Arizona, USA (Available from Pylam Products) 0.1 g of food grade canola oil dyed with dye is added thereto and the vial is capped. The vial is shaken vigorously for 5 seconds by hand and left to stand until clear or 5 minutes has elapsed through the ISO 7027 turbidity measurement procedure, whichever comes first. The ISO 7027 method measures turbidity at a wavelength of 880 nm using a turbidity measurement facility, such as that available from Omega Engineering, Inc., Stamford, Conn. Once the vial becomes clear, additional oil is added in increments of 0.1 g until the vial is not clear within the defined time. The oil solubility (%) is recorded as the maximum amount of oil that has been successfully solubilized (ie, the vial became clear) by 10.0 g of product. Preferably, the dishwashing compositions of the invention 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% Solubilize canola oil.

The foam generation profile can be measured by the use of a suds cylinder tester (SCT) and by the use of data for the plot of the foam generation curve. SCT has a set of four cylinders. Each cylinder is typically 30 cm in length and 10 cm in diameter. The wall of the cylinder is 0.5 cm thick and the bottom of the cylinder is 1 cm thick. The SCT rotates the test solution in a closed cylinder, typically a plurality of transparent plastic cylinders, at a speed of about 2.2 rad / s (21 rpm) for 2 minutes, after which the height of the foam is measured. Contaminants are then added to the test solution, stirred again and the height of the resulting foam is measured again. Since additional contaminants are introduced from the surface to be cleaned, such tests may be used to simulate the initial foam generation profile and in-use foam generation profile of the composition.

The foam generation profile test is as follows:

1. Prepare a graduated set of clean, dry cylinders and water with a water hardness of 136.8 ppm (2.1 grains / liter) and a temperature of 25 ° C.

2. Add the appropriate amount of test composition to each cylinder and add water so that the total composition + water in each cylinder is 500 mL.

3. Seal the cylinder and place it in the SCT.

4. Turn on the SCT and rotate the cylinder for 2 minutes.

5. Within 1 minute, measure the height of the foam in centimeters.

6. The foam generation profile is the average level of foam in cm generated by the composition.

The maximum foam generation profile of the composition according to the invention is preferably at least about 2 cm, more preferably at least about 3 cm, even more preferably at least about 4 cm.

The foam to weight ratio is a measure of mL units of foam generated per gram of product. The foam to weight ratio is measured as follows: The weight of the container is obtained by weighing a volumetric device, for example a graduated cylinder. The product is then dispensed into the graduated cylinder with a set number of strokes for a discontinuous dispensing device or for a set time for a continuous dispensing device, if appropriate. 10 strokes for non-continuous units (pumps, sprayers) or 10 seconds for continuous units is the proposed duration. The dispensing rate in the test should match the dispensing rate during normal use scenarios. For example, 120 strokes per minute for a trigger sprayer or 45 strokes per minute for a palm pump.

The volume of foam generated is measured in mL using a volumetric device.

The volumetric device containing the dispensed product is weighed in grams. The vessel weight of the volumetric device is subtracted from this weight. The result is grams of product dispensed. Finally, the foam to weight ratio in mL / g is calculated by dividing the volume of foam generated in mL by the weight of the dispensed product in g.

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

Examples of the present invention are shown below for illustrative purposes, which are not intended to limit the present invention in any way. This embodiment should not be construed as limiting the invention, since many modifications of the invention are possible without departing from the spirit and scope of the invention.

Example 1

The foaming kit includes a 300 mL hollow plastic container filled with a microemulsion type dish washing composition, and an attached T1 series foam generator made of Airspray similar to that shown in FIG. 1. The T1 bubble generator is modified to include a third mesh at the tip 41 of the nozzle as shown in FIG. 1. Also included is a molding applicator according to FIG. 3. The foamed dishwashing composition has a foam to weight ratio of about 3 mL / g upon dispensing, and the foam has a creamy, uniform look and feel. The foamed dishwashing composition is dispensed from the foaming dispenser into the pocketed molding applicator by inserting the nozzle of the foaming dispenser into the mouse of the pocketed molding applicator and pressing on the actuator. When used as described above, the dishwashing kit provides excellent mileage and foam that lasts throughout normal use for cleaning dishware. However, when no foaming dispenser is used (ie, the dishwashing composition is simply poured from the container), the effective foaming dilution range does not significantly overlap with the effective oil solubilization dilution range.

Example 2

A microemulsion of an ionic substrate packaged with the foaming distributor of Example 1 is provided.

Example 3

A foaming 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 that is cut and shaped and is firmly attached to the inside of the nozzle. The foam generated is creamy and aesthetically pleasing.
