Description

Aerosol product comprising a foaming concentrate composition comprising particulate material

Technical Field

The present invention relates to a foamed aerosol product comprising particulate material, which is dispensed from a package comprising a powder valve.

Background

Personal care and home care compositions containing larger particles are becoming increasingly popular. Personal care compositions containing larger particles such as polyethylene beads provide skin exfoliation benefits or skin feel benefits. Household care compositions comprising relatively large particles scrub soils from hard surfaces such as dishes. Such products also typically generate foam to aid in cleaning the surface treated with the composition.

Such compositions are typically dispensed from hand pump packages by manually actuating the hand pump or from bottles by manually squeezing the bottle. After dispensing, it is generally necessary to add water and manually rub the composition to create a foam or lather so that the composition can be used to clean the surface being treated.

Aerosol packaging is one method of generating a large amount of foam from a foam composition when dispensed. However, attempts to deliver foam products containing larger particulate matter in aerosol products can result in clogging of valves or leakage, rendering the product useless. The particle size of the particulate material dispensable through the aerosol valve has historically been a maximum of 100 microns (μm) and for most products the particle size should be below 50 μm. See, e.g., Paul a. sanders PRINCIPLES OF AEROSOLTECHNOLOGY, page 314 (Van nonstrand Reinhold co., 1970).

It is therefore desirable to develop a product that includes larger particulate matter that can generate foam when dispensed.

Summary of The Invention

The present invention relates to an aerosol product comprising a foaming concentrate composition and a propellant, the product being contained in a package comprising a powder valve and a container. The foaming masterbatch composition comprises at least about 0.1%, by weight of the foaming masterbatch composition, of a particulate material having a particle size of at least about 100 μm. The powder valve includes an orifice having an orifice diameter of at least about 0.026 inch (660 μm). Preferably, the ratio of the maximum particle size of the particulate matter to the orifice diameter is less than about 0.75. The present invention provides a cleansing composition that foams upon dispensing and contains relatively large particulate material to provide benefits such as skin peeling or hard surface scrubbing while avoiding clogging or leakage of the aerosol valve.

Detailed Description

Foaming master batch composition

The aerosol products of the present invention include a foaming concentrate composition for cleaning a variety of surfaces such as skin, hair, or hard surfaces such as dishes, floors, and the like. The foaming concentrate composition comprises a surfactant and at least 0.1%, by weight of the foaming concentrate composition, of a particulate material having a particle size of at least about 100 μm. The foaming masterbatch composition may also include a number of optional ingredients.

Preferably, the foaming concentrate of the present invention generates foam when dispensed from a package containing the foaming concentrate, without requiring the consumer to generate foam after dispensing by rubbing the foaming concentrate (i.e., post-foaming composition) by hand.

Particulate material

The foaming concentrate composition of the present invention comprises from about 0.1% to about 10%, preferably from about 0.3% to 6%, more preferably from about 0.5% to about 3%, more preferably from about 1% to about 3%, and more preferably from about 1.5% to about 2.5%, by weight of the foaming concentrate composition, of particulate matter. The foaming concentrate composition of the present invention comprises at least about 0.1%, preferably at least about 0.25%, more preferably at least about 0.5%, and more preferably at least about 1%, by weight of the foaming concentrate composition, of particulate matter having a particle size of at least about 100 μm, preferably at least about 150 μm, and more preferably at least about 200 μm. In the foaming concentrate compositions of the present invention, the larger size of the particulate material can provide a variety of benefits, such as skin exfoliation or hard surface scrubbing. In addition, the foaming masterbatch composition of the invention may optionally further comprise particulate matter having a particle size of less than 100 μm. The particulate material of the present invention preferably has a maximum particle size of less than about 600 μm, preferably less than about 500 μm, more preferably less than about 400 μm, and more preferably less than about 350 μm. The maximum particle size of the particulate matter can be measured based on the sieve passed through.

The particulate matter of the present invention may be derived from a variety of materials, including those of inorganic, organic, natural and synthetic origin. These particles are supplied in all different sizes and shapes that can affect their ability to be used in aerosol products. Particle size is typically controlled and/or measured by the ability of the particles to pass through a particular mesh. The screen will allow the particles to pass through as long as the particles are smaller than a particular size along one axis. Furthermore, the different ways in which the beads, and in particular the polymers (e.g., polyethylene or polypropylene), are manufactured can affect the roughness of the particles. Thus, it is to be understood that not only the size and shape of the particles, but also the external roughness of the particles, can affect the passage of the particles through the valve, as smoother particles tend to pass more easily through the valve orifice in the package of the present invention than coarser particles. The ratio of the maximum particle size of a particular material to the orifice diameter of a valve on a package may be particularly important to prevent the orifice from becoming clogged with particulate matter. The ratio of the maximum particle size to the orifice diameter is generally less than about 0.75, preferably less than about 0.7, more preferably less than about 0.6, more preferably less than about 0.5, and more preferably less than about 0.4.

Non-limiting examples of suitable propellants include hydrocarbons, nitrogen, carbon dioxide, nitrous oxide, air, 1-difluoroethane supplied by Dupont as Dymel 152A (hydrofluorocarbon 152A), dimethyl ether (DME), and mixtures thereof. Preferred are hydrocarbon propellants and hydrocarbon/dimethylether propellant blends, specific examples of which include propane, butane, isobutane, and dimethylether. Most preferred are hydrocarbon propellants comprising a mixture of propane and isobutane or a mixture of propane, isobutane and dimethyl ether, specific examples of which include Aeron A-46 and Aeron A-70 (both commercially available as Diversified CPC alone or as a blend with dimethyl ether). Those of ordinary skill in the art of aerosol products recognize that geographic jurisdictions may dictate the level of volatile organic chemicals, such as propellants.

Package (I)

The foaming concentrate composition of the invention and propellant are packaged in a package comprising a container and a powder valve comprising an orifice having an orifice diameter of at least about 0.026 inch (660 μm).

Powder valve

The packages of the present invention comprise a powder valve comprising an orifice having an orifice diameter of at least about 0.026 inch (660 μm), preferably at least about 0.027 inch (685 μm), and more preferably at least about 0.030 inch (762 μm). As used herein, the term "orifice diameter" refers to the maximum distance on opposite sides at the orifice opening. The powder valve will have one, two, three, four or more orifices, preferably one or two orifices, on the valve stem. Each orifice diameter of the present invention may have the same or different orifice diameters. Preferably, the orifices have the same orifice diameter. The orifice may be in the form of a variety of shapes, such as circular, square, rectangular, oval, trapezoidal, and the like. The orifice shape may be selected based on the shape of the particulate material used in the foaming masterbatch composition. Preferably, the apertures are circular or rectangular and the particulate matter is generally spherical or elliptical. The orifice preferably has at least about 0.340mm²More preferably at least about 0.400mm²And more preferably at least about 0.450mm²The open area of (a).

In a conventional form of aerosol valve, the upper level is urged upwardly into a sealing position against a valve sealing gasket by a spring acting on the valve body when the aerosol valve is in a closed condition. One or more orifices in the valve stem are disposed above a lower surface of the valve gasket when the valve is in the closed position. When the valve is opened by pressing a button, the valve stem moves downward and its orifice or orifices will move to a position below the gasket. The foaming concentrate composition in the aerosol container can then be forced up through the orifice, under the influence of the propellant, into the valve stem and then dispensed through the nozzle.

Powder valves typically have the orifice of the valve stem located above the sealing gasket in the closed position, or at least the upper half of the sealing gasket in the closed position, to keep particulate matter from leaking between the sealing gasket and the orifice. Conventional aerosol valves typically have clogging problems when dispensing compositions containing particulate matter of any size. The powder valve of the present invention helps prevent clogging of the aerosol product by frictionally closing the orifice opening against the sealing gasket as the valve moves from the open position to the closed position. In addition, powder valves typically have different shapes on the valve body to keep particulate matter from clogging on the sealing surfaces. Non-limiting examples of suitable powder valve configurations are described in detail in U.S. Pat. nos. 3,773,064, 5,975,378 and 6,394,321.

One embodiment of the powder valve of the invention in the closed position is shown in the figures. The powder valve assembly 10 generally includes a dip tube 12, a valve housing 14, a valve closure coil spring 16, and a valve body 18. The valve body 18 has a hollow valve stem 20 extending upwardly therefrom and includes at least one orifice 22 opening into the interior of the valve stem 20. The sealing washer 24 is preferably made of a resilient material such as rubber. As shown, when the powder valve is in the closed position, the sealing gasket 24 surrounds the valve stem 20 and seals the aperture 22. An actuator 26 having a nozzle 28 is attached to the top of the valve stem 20. When the actuator 26 is pressed downward against the spring force of the coil spring 16, the orifice 22 passes under the sealing gasket 24, and the foamable concentrate composition in the container can pass upward through the dip tube 12, into the valve body 18, through the orifice 22, into the valve stem 20, into the actuator 26, and finally out through the nozzle 28. When the actuator 26 is released, the coil spring 16 presses the valve stem 20 and the orifice 22 upward against the sealing gasket 24, wiping any residual foaming concentrate composition from the orifice 22 of the valve stem 20 to prevent clogging of the orifice 22 and blocking of the flow of the foaming concentrate composition.

Container with a lid

The container of the present invention may be a variety of aerosol containers known in the art. The container may be a single compartment container or a barrier container. Non-limiting examples of single-compartment containers include plastic, glass, aluminum, or steel containers, which may be unlined or lined with materials such as epoxy novolac, organosols, and polyamideimide. In such single-compartment containers, the foaming concentrate composition and propellant are mixed in a single compartment. The barrier container is within the container, keeping the foaming concentrate composition physically separated from the propellant. Non-limiting examples of barrier containers include piston containers and bag-in-can type containers.

Actuator

The actuator of the present invention may be a variety of actuators known in the art. The actuator may be a front hinge, a rear hinge, or a hingeless actuator, so long as the actuator is properly mated with the valve stem. Non-limiting examples of suitable hinge actuators include those for upright containers available under the tradenames S30, S25, S20, and Allegra from Seaquist Perfect Dispensing, and for inverted containers available under the tradenames S16 and S4. Hingeless actuators may be preferred for the present invention as they tend to exhibit less lateral pressure during actuation of the aerosol product. Non-limiting examples of suitable hingeless actuators include those available from Precision Valve under the tradenames City Spout, Hercules Spout, and Iris and those available from SeaquistPerfect Dispensing under the tradename S2.

the foaming master batch compositions of examples 1 to 7 were prepared as follows. If a clay suspending agent is present in the composition, the clay is added to deionized water and mixed until fully hydrated. If present in the composition, hydrophobic conditioning agents, hydrophilic conditioning agents (which should be liquid when added), additional suspending agents and/or fatty acids are then added. If a fatty acid or petrolatum is present, gentle heating may be performed to melt the fatty acid or to more easily incorporate the petrolatum. If the pH is less than the desired value, a pH control agent (typically a base such as triethanolamine or sodium hydroxide) is added to increase the pH to the desired value. If the pH is greater than desired, a pH control agent (typically an acid such as citric acid) is added to reduce the pH to the desired value. Any additional ingredients, such as particulate matter, preservatives, fragrances, colorants/pigments, etc., are then added.

The foamed masterbatch compositions of examples 1 to 7 were then individually filled into polyamide imide lined aluminum cans from cclind industries, inc. The powder valve was inserted into each liquid filled can and then crimped. The powder Valve used had a Valve stem with an orifice selected from a circular orifice with an orifice diameter of 0.030 "(available from Precision Valve), a rectangular orifice with dimensions of 0.027" tall by 0.045 "wide (i.e., an orifice diameter of 0.045"), or a laser-cut square orifice with dimensions of 0.030 "tall by 0.030" wide (i.e., an orifice diameter of 0.030 "). Then, a propellant is charged into each can in a desired amount. An actuator is then installed on each can for dispensing the foaming concentrate composition. The actuator is available from Seaquist Perfect Dispensing under the trade name S-30.
