    “GRANULAR FOAM COMPOSITION, E, METHOD OF PRODUCTION AND DISPENSATION OF A GRANULAR FOAM” FIELD [001] The present description refers to formulations for a granular foam dispenser.
    FUNDAMENTALS [002] Currently, there are three (3) broad categories of hand cleaning products that are outside the domestic skin care market. They are: lotion soaps, lotion soaps with mechanical exfoliating agents in suspension and foam soaps. Lotion soaps are usually dispensed from soap dispenser pumps or pump-top bottles. Lotion soaps with mechanical exfoliating agents are also dispensed through similar devices. Foaming soaps are dispensed from special pumps that mix air and fluid together through a porous medium to produce foam.
    [003] Hand cleaning products have been around for many years. The combination of ingredients in these types of soaps can be specified to achieve a wide range of cleaning characteristics. The viscosity of this form of soap is in the range of 5,000 to 30,000 cPoise and is generally adapted to be easily manipulated in the user's hand or pumped through a pump.
    [004] With the addition of mechanical exfoliating agents, the performance of cleaning lotion soaps can be enhanced. Lotion soaps with mechanical exfoliating agents in suspension tend to have a viscosity range at the lower end that is higher than that of basic lotion soaps. In order to provide the structure for suspension mechanically exfoliating agents of an appropriate size to provide cleaning benefits, these

    2! Ί formulations must also have a critical deformation force (or yield value) greater than or equal to 30 dynas / cm, associated or not, with non-Newtonian rheological behavior and, more particularly, plastic or thixotropic properties (pseudoplastic fluids being excluded from this requirement). The rheology of this form of soap must be viscoplastic (Casson, or Bingham, or dilating fluids, or thixotropic, or rheopectic) with a critical deformation force that is preferably greater than or equal to 30 dynas / cm 2 . The critical deformation force is defined as the stress that must be applied before the flow starts and, although related to viscosity, it is more dependent on the characteristics of the rheological additive used. The critical deformation force has traditionally been determined by measuring the material's viscosity at two speeds using a Brookfield viscometer. As the spindle rotation speed is increased, materials that are subjected to pseudoplasticity result in a lower viscosity measure.
    [005] The critical deformation force of the soap or the required yield value can be calculated as follows:
    Yield Value (in dynas / cm 2 ) = (Vo.5 fpm - V rom ) / 100
    Required Yield Value (in dynas / cm 2 ) = [4/3 R (D-Do) gj where:
    R = particle radius (cm)
    D = particle density (g / cm 3 ) Do = average density (g / cm 3 ) g = acceleration due to gravity = 980 cm / s 2 [006] Foaming hand cleaners offer many benefits over cleaning products hand cleaner in lotion. Foam products are faster and easier to use, since they are dispensed in the user's hand in a foamed format. Hand cleaning products
    Petition 870190063128, of 07/05/2019, p. 17/63 / 17 foam spreads more effectively than hand lotion cleansers, providing better cleaning performance with less product. Since foaming hand cleaning agents are already foamed, there is less water needed in the cleaning process and the user can clean their hands in less time. The viscosity range of this form of hand cleaner is less than 100 cPoise and is adapted to be easily mixed with air through a porous medium to produce foam from a pump.
    [007] The characteristics of foam soaps are such that they are not able to form suspension of mechanical exfoliating agents of sufficient size to provide cleaning benefits. Current foam pump technologies mix air and fluid together and pass it through a porous medium to make the foam. The porous medium is generally very fine and will sieve mechanical exfoliating agents.
    [008] Currently, a new type of pump capable of dispensing cleaning products for manual mechanical exfoliation agent in a bubble shape by a aerosol dispensing system has not been developed (see U.S. Patent Nos 8,002. 151 and 8,281,958). This allowed the creation of a new category of hand cleaning agent. This category is cleaning products for foaming hands with mechanical exfoliating agents. This new category will allow you to leverage all the benefits associated with hand cleaning products with the enhanced cleaning performance provided by mechanical exfoliating agents. However, the requirement remains for an appropriate hand cleaner.
    [009] Thus, it would be very beneficial if a hand cleaner could be formulated that can form a suspension of particulate mechanical exfoliating agents with particles sized about
    Petition 870190063128, of 07/05/2019, p. 18/63 / 17
    100 microns to about 800 microns that decrease in viscosity when exposed to high shear rates and are capable of being foamed through a non-aerosol depressurized pump dispenser.
    [0010] If the formulation is too fine, the mechanical exfoliating agents become suspension. If the product is too thick, the amount of force required to foam the foam formulation becomes too high, resulting in excessive operating force for the dispenser user and the poor quality foam.
    [0011] The state of the art does not capture the formulation requirement to generate foam when mixed and dispensed with air from a non-aerosol dispenser. The prior art hypothesis is that the soap will foam naturally. Although this may be true if mechanical manipulation is done (rubbing in the hand), if the formulation does not have the desired characteristics, it will not create an acceptable foam through a non-aerosol pump.

    DETAILED DESCRIPTION OF THE INVENTION [0016] Various embodiments and aspects of the present description will be described with reference to the details discussed below. The following description and drawings are illustrative of the description and are not to be construed as limiting the description. Numerous specific details are described to provide an exhaustive understanding of various embodiments of the present description. However, in certain cases, well-known or conventional details are not described in order to provide a concise discussion of embodiments of the present description.
    Definitions:
    [0017] As used herein, the terms, understand and understand are to be constructed as being inclusive and open and not exclusive. Specifically, when used in this specification including claims, the terms, understand and understand and their variations mean the features, steps or
    Petition 870190063128, of 07/05/2019, p. 21/63 / 17 specified components are included. These terms should not be interpreted to exclude the presence of other characteristics, steps or components.
    [0018] As used herein, the term exemplary or example means that it serves as an example, case, or illustration, and should not be interpreted as preferred or advantageous over other configurations described herein.
    [0019] As used herein, the terms about and approximately, when used in conjunction with ranges of particle sizes, mixtures compositions or other physical properties or characteristics, are intended to cover minor variations that may exist in the upper limits and lower ranges of dimensions so as not to exclude embodiments in which, on average, most dimensions are satisfied, but in which dimensions may exist statistically outside this region. It is intended to exclude embodiments such as these from the present description.
    [0020] As used herein, the phrase non-Newtonian thickener or non-Newtonian thickener, means a category of fluids whose viscosity (resistance to deformation or shear forces) is influenced by the shear stress and / or by the time this force is applied .
    [0021] As used herein, the phrase “critical deformation force” (also referred to as “yield value”) refers to a term used in rheology in which the “critical deformation force” is the minimum force that must be applied to a material to induce viscous flow. The critical deformation force is a measurable amount (expressed in dynas / cm 2 ). More particularly, the two phrases refer to the same phenomenon that is even a certain force exerted (the critical deformation force), a material
    Petition 870190063128, of 07/05/2019, p. 22/63 / 17 viscoelastic will exhibit solid type or elastic properties, that is, it will not have a liquid flow. Above the critical deformation force (or above the yield value) the same material will exhibit viscous properties, that is, it will flow.
    [0022] As an example, for granules (particles of cleaning agent particulate in the present context) suspended in a fluid, provided that the deformation force conferred by the suspended granules is less than the critical deformation force (or less than than the yield value), the granules will remain in suspension forever. If they exert a force greater than the critical deformation (or yield value), then they will migrate over time, and float to the top of the fluid or sediment at the bottom.
    [0023] As used herein, the phrase non-aerosol dispenser or depressurized dispenser means a dispenser that does not have a propellant stored as the gas source to create the foam structure within the hand cleaner.
    [0024] Foam, as used herein means a fluid and gas mixed to form a mass of small bubbles that have a structure that lasts for a variable period of time.
    [0025] The phrase low pressure in the context of foam production as used herein means a pressure of about the atmosphere or less, such as when the foam is dispensed from a depressurized container. Typically, when foams are dispensed from aerosol containers the foam is considered to be dispensed under high pressure conditions.
    [0026] The present description provides a skin cleansing product, which is a foaming granular composition that can suspend particles of mechanical cleaning agent having a size in the range from
    Petition 870190063128, of 07/05/2019, p. 23/63 / 17 about 100 to about 800 microns which decreases in viscosity when exposed to high shear rates and is capable of being foamed through a non-aerosol (depressurized) pump.
    [0027] If the formulation is very fine (very low viscosity) and has a Newtonian rheological behavior, the mechanical exfoliation agents will become suspended. If the product is too thick (too viscous), the amount of force required to foam the formulation becomes too high, resulting in excessive operational strength for the dispenser user and results in poor foam quality.
    [0028] While it is assumed in the field that if surfactants are present, they naturally foam. However, while this is a necessary condition, it has been found that it is not a sufficient condition to obtain a foam when particulate cleaning agents are present. Firstly, the fluid must be able to become sanded, and secondly, it must be able to stabilize the entrained air bubbles divided by fluid films. The presence of surfactants in an appropriate concentration largely satisfies the second of these requirements, providing a means of stabilizing fluid films by establishing a surface tension gradient that acts to oppose drainage forces and, consequently, maintains the thickness of the films, avoiding collapse.
    [0029] However, the presence of surfactants alone does not satisfy the first requirement, which requires that the fluid has sufficiently low viscosity to allow mixing with air, under the conditions provided by the pump (that is, without the need for a excessive force). If the fluid is too viscous, the air will not mix and therefore will not form bubbles (and, therefore, it cannot be stabilized as foam). This issue is central to providing a viscosity fluid low enough to allow efficient mixing and consequently foaming, and
