Description

Title of the invention: CLEANING COMPOSITION IN THE FORM OF A STABLE FOAM AND METHODS OF USE SCOPE OF DISCLOSURE

[0001] This disclosure relates to cleansing compositions in the form of stable foam and processes for cleaning hair or the body with the compositions. CONTEXT

[0002] Most "dirt" contains traces of oil and grease that adhere to the surface of skin and hair. Rinsing with water alone is insufficient to adequately remove oil and grease. The main functional ingredients in cleansing compositions are surfactants. Surfactants interact with water, enabling it to "wet" surfaces more effectively. The surfactant-water combination is then able to surround small stains of dirt and wash them away. Agitation of the aqueous solution, for example by rubbing hands together while washing or lathering shampoo in the hair, also facilitates the dirt removal process.

[0003] Conventional cleaning compositions, such as shampoos, contain surfactants in varying amounts. Anionic surfactants are typically included because they impart a foaming effect to a composition. Nonionic surfactants may also be included to provide cleansing, solubilizing, and dispersing properties, but are usually less irritating than anionic surfactants. However, nonionic surfactants often have a lower foaming capacity and do not provide any improvement in viscosity (for example, a composition is often thinner and more fluid with increased amounts of nonionic surfactants). In some cleaning applications, a higher viscosity is desirable for handling or ease of application. In addition, personal care products with a higher viscosity are more aesthetically appealing to many consumers..

[0004] The development of cleansing compositions has been driven by a need for certain performance properties that consumers find desirable. For example, consumers seek cleansing compositions that lather and clean well, have a certain "thickness" (viscosity), and are gentle on the skin and hair. Cleansing compositions must also be easily rinsed from the body. However, the addition of a particular component to a A cleaning formula will often enhance one desired property at the expense of another. Therefore, achieving a perfect balance between desired performance properties is difficult.

[0005] Consumers appreciate cosmetic products that offer unique sensory properties in addition to their intended cosmetic properties. Skin and hair care products are often creamy emulsions or dispersions comprising an aqueous phase and a hydrophobic phase. Emulsion or dispersion-type cosmetic products can be unsatisfactory, particularly cleansing products. They tend to be heavy and greasy and often do not cleanse hair or skin satisfactorily. Gel-type products have been developed, which typically contain various types of thickeners, especially thickening polymers. Thickening polymers are sometimes used to improve the viscosity of cleansing compositions, but they can reduce the effectiveness of surfactant systems, compromise stability, and may even fail to thicken as desired.

[0006] Cleaning products in the form of unstable foams, generated temporarily by the user just before use, are known. Unstable foam products include aerosol products that form a foam upon use by means of a propellant gas in a pressurized container. Alternatively, unstable foam cleaners can be produced by dispensing a cleaning composition from a container using a mechanical pump connected to a foaming head that incorporates air into the cleaning composition during dispensing. These types of temporary foams decompose rapidly, generally within a few minutes, and require special conditioning and user action to generate the foam.

[0007] Whether a cleansing composition is pre-formed into foam before use or is formed into foam during dispensing from a container, cleansing compositions are known to automatically generate foam during use. When mixed with external water during the cleansing process, cleansing compositions automatically generate foam. This is due to the inclusion of cleansing surfactants, particularly anionic surfactants. Anionic surfactants contain a fatty group and a negatively charged head group that allows them to easily interact with water molecules and reduce the surface area between the water and oily substances, thus helping to remove debris, makeup, and oils from the skin or hair.Popular anionic surfactants used in cleaning compositions include alkyl sulfates, particularly sodium lauryl sulfate (SLS) and sodium laureth sulfate (SLES). While they offer good cleaning activity and contribute to the... Foaming during use can cause skin irritation in some sensitive individuals and may lead to dryness.

[0008] Unlike the cleaning products mentioned above, the cleaning compositions in this case do not require an aerosol system or any other special packaging or equipment to generate foam before use. The cleaning compositions are already in foam form. The foam structure is maintained stably from manufacture until use by consumers, which can last for months or even years. Although the cleaning compositions could certainly produce more foam during use, this is not necessary. There is no need to include surfactants that cause the cleaning compositions to foam during use because the compositions are already in foam form. This allows the use of milder, less aggressive anionic surfactants without concern about their ability to foam during use. DISCLOSURE SUMMARY

[0009] This disclosure relates to stable foam cleansing compositions containing a unique combination of acylglycinate surfactants, magnesium salts, and nonionic emulsifiers exhibiting a low hydrophilic-lipophilic balance (HLB). The inventors discovered that the acylglycinate surfactants interact with the magnesium salts to enhance and stabilize the foam cleansing compositions. The acylglycinate surfactants are anionic surfactants that impart cleansing properties to the compositions while interacting with the magnesium salts. The compositions are in foam form, have a unique microstructure, and possess a light and pleasant texture that consumers find appealing. The compositions are neither oily nor sticky. Furthermore, the foam cleansing compositions are highly effective at cleansing skin and hair without irritation or dryness.On the contrary, the cleansing formulas hydrate and regenerate the skin in a surprising way despite their high cleansing efficacy.

[0010] Cleaning compositions in the form of stable foam typically include: a. one or more acylglycinate surfactants, their salts, or combinations thereof; b. one or more magnesium salts providing divalent cations having a charge density of about 40 to about 200 C / mm3 and a solubility in water of at least 400 g / l; c. one or more non-ionic emulsifiers exhibiting a hydrophilic-lipophilic balance (HLB) of about 6 or less; d. one or more water-soluble solvents; and e. water.

[0011] The compositions typically have a lamellar liquid crystalline structure. Air or a gas may be incorporated into the composition to make it foam. Useful gases include inert gases, for example, nitrogen, carbon dioxide, nitrogen oxides, noble gases, or mixtures of these gases. In some cases, oxygen-free inert gases, such as nitrogen or carbon dioxide, are used, particularly when the cleaning composition includes one or more oxygen-sensitive ingredients. Cleaning compositions in stable foam form are unique in that special "foaming" equipment is required to generate the product in foam form, although special foaming equipment can certainly be used. For example, cleaning compositions in foam form can be "made into foam" using a mixer, whisk, beater, blender, and the like.

[0012] Foaming cleaning compositions typically have a specific gravity of about 0.6 to about 0.8 g / ml at 25 °C, preferably about 0.65 to about 0.8 g / ml at 25 °C, and more preferably about 0.7 to about 0.8 g / ml at 25 °C. Surprisingly, foaming cleaning compositions remain stably in foam form; for example, the initial specific gravity of the foaming composition is essentially unchanged over time, for example, when stored at 25 °C for 2 months.

[0013] Non-limiting examples of acylglycinates include sodium cocoylglycinate, sodium lauroylglycinate, sodium myristoylglycinate, potassium lauroylglycinate, potassium cocoylglycinate, or mixtures thereof. Sodium cocoylglycinate is particularly useful.

[0014] Non-limiting examples of magnesium salts providing divalent cations having a charge density of about 40 to about 200 C / mm3 and a water solubility of at least 400 g / 1 include magnesium chloride, magnesium sulfate, magnesium thiosulfate, magnesium pyrrolidone carboxylate (magnesium pidolate), magnesium gluconate, or mixtures thereof.

[0015] The term "hydrophilic-lipophilic balance" ("HLB") of a surfactant is a measure of its degree of hydrophilicity or lipophilicity, determined by calculating the molecular weight percentages of the hydrophilic and lipophilic portions of the surfactant molecule. Non-limiting examples of nonionic emulsifiers exhibiting a hydrophilic-lipophilic balance (HLB) of approximately 6 or less include sorbitan esters, glyceryl esters, glycol esters, polyglyceryl esters, glycol esters, sucrose esters, methylglucose esters, ethoxylated methylglucose esters, or mixtures thereof. In some cases, glycol esters and / or glyceryl are particularly useful. Non-limiting examples include glycol distearate, glycol hydroxystearate, glycol oleate, glycol ricinoleate, glycol stearate, propylene glycol isostearate, propylene glycol hydroxystearate, propylene glycol laurate, propylene glycol myristate, propylene glycol oleate, propylene glycol ricinioleate, propylene glycol stearate, or mixtures thereof.

[0016] The foaming cleaning composition typically includes substantial amounts of one or more water-soluble solvents (or "water-soluble organic solvents"). Non-limiting examples of water-soluble solvents include glycerin, C2-C6 monoalcohols, polyols (polyhydric alcohols), glycols, and combinations thereof. In some cases, water-soluble solvents selected from glycerin, glycols, or mixtures thereof are particularly useful. Non-limiting examples of glycols include ethylene glycol, propylene glycol, butylene glycol, hexylene glycol, pentylene glycol, diethylene glycol, dipropylene glycol, caprylyl glycol, or mixtures thereof.

[0017] Foaming cleaning compositions typically include water, for example, in amounts from about 5% to about 60% by weight, relative to the total weight of the cleaning composition before it is transformed into foam. In any case, the amount of water may be similar to the amount of one or more water-soluble solvents. For example, the weight ratio of one or more water-soluble solvents may be from about 0.5:1 to about 8:1. Furthermore, the weight ratio of one or more water-soluble solvents may be from about 1:1 to about 5:1.

[0018] The stable foam cleaning composition may optionally include one or more additional salts, other than magnesium salts, providing divalent cations with a charge density of approximately 40 to approximately 200 C / mm³ and a water solubility of at least 400 g / L. For example, in various embodiments, the stable cleaning composition includes one or more salts providing monovalent cations. Non-limiting examples include sodium chloride, potassium chloride, sodium sulfate, potassium sulfate, ammonium chloride, monoethanolammonium chloride, or mixtures thereof. Particularly preferred salts providing monovalent cations include sodium chloride, potassium chloride, or mixtures thereof.

[0019] Cleaning compositions in the form of a stable foam optionally include one or more thickening agents. The unique characteristics of stable cleaning compositions include their stability, viscosity, and pleasant texture. Surprisingly, these characteristics are achieved without the need for a thickening agent. Thickeners are often necessary to ensure viscosity, stability, etc. sufficient. Although thickening agents are not required for the stable foam cleaning compositions of the present invention, they may optionally be included and, in some cases, preferably included in the stable foam cleaning compositions. Furthermore, the stable foam cleaning compositions may be free or substantially free of one or more thickening agents. Non-limiting examples of thickening agents include thickening polymers, such as anionic, cationic, amphoteric, and nonionic thickening polymers, and non-polymer thickening agents such as clays (e.g., smectite, hectorite, and montmorillonite, etc.).

[0020] In various embodiments, the cleansing compositions in the form of a stable foam include one or more miscellaneous ingredients. Non-limiting examples include preservatives, perfumes, pH adjusters, salts, chelating agents, skin active ingredients, buffers, antioxidants, flavonoids, depigmenting agents, anti-wrinkle agents, vitamins, botanical extracts, UV filtering agents, proteins, protein hydrolysates and / or isolates, fillers (e.g., organic and / or inorganic fillers such as talc, calcium carbonate, silica, etc.), compositional colorants, etc.

[0021] This disclosure also relates to cleaning products comprising stable cleaning compositions. Such products may have a container or packaging to house or contain the cleaning composition in the form of a stable foam. Non-limiting examples of useful containers or packaging include bottles, tubes, jars, cans, bags, boxes, and the like. Cleaning compositions in the form of a stable foam are usually transformed into foam before being incorporated into a container or packaging and remain stably in foam form within the container or packaging. Therefore, the container or packaging does not require a foam-generating mechanism, such as a foam actuator or a foam nozzle.Similarly, the cleaning product is not typically an aerosol-type product, meaning that it does not require a propellant and a mechanism to form a foam. It is conceivable that a pressurized or aerosol-type container could be used to hold the cleaning composition in the form of a stable foam, but it would not be strictly necessary to create the foam and could be used to conveniently dispense the cleaning composition already in foam form from a container.

[0022] Cleaning compositions in the form of stable foam exhibit excellent cleaning, stability, and moisturizing properties. Thus, the present disclosure This concerns processes for cleaning a substrate, such as skin, hair, or a combination thereof. The processes involve applying an effective amount of a cleansing composition in the form of a stable foam to the substrate (e.g., hair, skin, or a combination thereof) and removing the composition from the substrate by rinsing. Typically, the cleansing composition in the form of a stable foam is massaged or rubbed over / on the entire substrate, optionally with external water, to dislodge, absorb, and remove material from the substrate. Cleansing compositions in the form of a stable foam not only clean but can also moisturize and regenerate hair and / or skin. Therefore, this disclosure also encompasses processes for moisturizing and / or regenerating hair and / or skin. BRIEF DESCRIPTION OF THE DRAWING

[0023] An implementation of this technology is described, by way of example only, with reference to the attached figure, in which:

[0024] [Fig.1] The figure represents an image of a cleaning composition in the form of a stable foam according to the present disclosure after storage for 2 months (4 weeks) at 25 °C, having a specific weight of 0.81 g / ml. DETAILED DESCRIPTION OF THE DISCLOSURE

[0025] This disclosure relates to cleansing compositions in the form of a stable foam. The compositions are particularly useful for cleansing the body, including the skin and hair, moisturizing the skin and / or hair, and restoring the natural, radiant appearance of the skin and / or hair. As the name suggests, the "cleansing compositions in the form of a stable foam" are both "stable" and "in the form of a foam." They include a unique combination of one or more acylglycinate surfactants, one or more magnesium salts, and one or more nonionic emulsifiers with a hydrophilic-lipophilic balance (HLB) of approximately 6 or less. In addition, the cleansing composition in the form of a stable foam has an unusual and unique lamellar liquid crystalline structure.The inventors discovered that acylglycinate surfactants interact with magnesium salts to influence the rheology and stabilize the foam compositions containing them. These foaming cleansing compositions are particularly effective at cleansing skin and hair without irritation or dryness. On the contrary, and unexpectedly, these cleansing compositions moisturize and regenerate the skin despite their strong cleansing power.

[0026] Cleaning compositions in the form of stable foam include: a. about 8% by weight to about 40% by weight of one or more acylglycinate surfactants, their salts, or combinations thereof; b. about 0.5 to about 2% by weight of one or more magnesium salts providing divalent cations having a charge density of about 40 to about 200 C / mm3 and a solubility in water of at least 400 g / l; c. about 3% by weight to about 7% by weight of one or more non-ionic emulsifiers having a hydrophilic-lipophilic balance (HLB) of about 6 or less; d. approximately 25 to approximately 65% ​​by weight of one or more water-soluble solvents; and e. approximately 10 to approximately 55% water by weight;

[0027] in which, the composition has a lamellar liquid crystalline structure,

[0028] the composition has been transformed into foam by the incorporation of air or a gas throughout the composition;

[0029] the composition has a specific gravity of approximately 0.6 to approximately 0.8 g / ml at 25 °C, and

[0030] all percentages by weight are based on a total weight of the composition not transformed into foam.

[0031] The weight percentages of the various ingredients may be stated relative to the total weight of the composition before it has been foamed or relative to the total weight of the composition after it has been foamed. The incorporation of air or a gas into the composition (i.e., foaming the composition) does not change or substantially alter the weight percentages of the ingredients or the total weight of the composition. Throughout this disclosure, reference is made to weight percentages relative to the total weight of the composition before it has been foamed. In each case, the weight percentages may be considered to be the same weight percentages relative to the total weight of the composition after it has been foamed.

[0032] The expression "stable foam" can be replaced by the expression "permanent foam" and refers to the mass of the product / composition, which is characterized in that a gaseous substance in the form of gas bubbles is uniformly distributed throughout the entire product / composition and remains homogeneously distributed over a period of time of at least one week, preferably at least one month, and particularly preferably at least six months when stored at room temperature (25°C). Typically, the degree of foaming amounts to at least 10%, preferably at least 20%, of the product / composition in foam form. Gas bubbles of a size, for example, between approximately 0.0001 and approximately 10 mm, particularly preferably between approximately 0.01 and approximately 1 mm, are contained in the mass of the product / composition in foam form. The average diameter of the gas bubbles can be, for example, about 0.1 to about 0.8 mm, preferably about 0.2 to about 0.4 mm.

[0033] The term "approximately" means within + / - 5% of the stated number. For example, an amount "of approximately 1 by weight" may include an amount as low as 0.95% by weight or as high as 1.05. Similarly, an amount "of approximately 50" may include an amount as low as 47.5% by weight and as high as 52.5% by weight. The specific gravity of the cleaning compositions in stable foam form is described below (and throughout the patent memorandum) as having a maximum of "approximately 0.8 g / ml at 25 °C." The data in the examples show that the compositions with a specific gravity of 0.81 g / ml (composition E of the invention) and 0.83 g / ml (composition D of the invention) were stable. The specific gravitys of 0.81 and 0.83 g / ml are encompassed by the expression "approximately 0.8 g / ml." The quantity "about 0.8" ranges from 0.76 to 0.84 (quantity + / - 5% of 0.8).Consequently, the ranges described throughout the disclosure, for example, a range for a specific gravity "from about 0.6 to about 0.8 g / ml", can be written by omitting the word "about" as "0.57 to 0.84 g / ml". This range takes into account the minimum amount "about 0.6" and the maximum amount "about 0.8". The other ranges should be interpreted in the same way. More specifically, the specific gravity can be written as 0.57 to 0.84 g / ml at 25 °C, preferably 0.62 to 0.84 g / ml at 25 °C, more preferably 0.67 to 0.84 g / ml at 25 °C. In a preferred embodiment, the specific gravity is 0.7 to 0.83 g / ml at 25 °C.

[0034] The inventors have discovered that when cleaning compositions are in foam form with a specific gravity of approximately 0.6 to approximately 0.8 g / ml at 25°C, preferably approximately 0.65 to approximately 0.8 g / ml at 25°C, and more preferably approximately 0.7 to approximately 0.8 g / ml at 25°C, they remain particularly stable. The term "stable," as used throughout this disclosure, means that the cleaning compositions in foam form substantially retain their original volume; that is, the volume of the cleaning composition in foam form after it has been immediately prepared does not change substantially over time.For example, the cleaning composition in stable foam form may have a specific weight of about 0.6 to about 0.8 g / ml at 25 °C, preferably about 0.65 to about 0.8 g / ml at 25 °C, more preferably about 0.7 to about 0.8 g / ml at 25 °C immediately after manufacture and may also have a specific weight of about 0.6 to about 0.8 g / ml at 25 °C, preferably about 0.65 to about 0.8 g / ml at 25 °C, more preferably about 0.7 to about 0.8 g / ml at 25 °C, after storage at 25 °C for at least 2 weeks, preferably after at least 4 weeks, more preferably after at least 2 months (or 8 weeks), again. more preferably after at least 6 months (26 weeks). In addition, in various embodiments, the specific weight of the cleaning composition in stable foam form immediately after manufacture does not change by more than 25%, preferably not by more than 20%, more preferably not by more than 15% by weight, even more preferably not by more than 10%, and ideally not by more than 5% after storage at 25°C for at least 2 weeks, preferably at least 4 weeks, more preferably at least 2 months (or 8 weeks), even more preferably after at least 6 months (26 weeks).

[0035] Cleaning compositions in the form of stable foam are unique in that special "foaming" equipment is required to generate the product in foam form, although such equipment can certainly be used. For example, cleaning compositions in the form of stable foam can be "made into foam" using a standard mixer, whisk, beater, blender, and the like. The forced introduction of air and / or an inert gas, or the formation of foam with these gases, can be achieved using suitable equipment specifically designed for this purpose, for example, a high-speed agitator or stirrer, so that a gas from the surrounding atmosphere (preferably air) is introduced into the mass.Foam formation can also occur when the unfoamed composition is passed through a mixer, which has a mixing head and a feed device with respective fittings for the simultaneous introduction of the composition and gas into the mixing head. The composition can be treated with a gas, preferably air, CO2, or nitrogen, in a gas mixing unit (e.g., such as a Euromix or top-mix dynamic foam generator from a Hansa Industry mixer, or with an Ultra Turax laboratory mixer).

[0036] The use of nitrogen is particularly preferred, for example, when the stable foam cleansing composition includes oxygen-sensitive ingredients. For example, various vitamins, antioxidants, and skin-active agents, etc., which may be included in stable foam cleansing compositions, can be oxygen-sensitive (i.e., oxygen can oxidize, discolor, inactivate, or destabilize the ingredients or even the compositions as a whole). The forced introduction of air and / or an inert gas is preferably in the range of 20 to 200%. The forced introduction or the action of the air and / or inert gas influences the structure and consistency and can be adjusted as needed.

[0037] Cleaning compositions in the form of stable foam typically have an opaque or white and creamy appearance.

[0038] Due to their strong cleansing and moisturizing properties, cleansing compositions in the form of a stable foam are particularly useful as Skin cleanser, hair cleanser (shampoo), body cleanser, cleansing and moisturizing cleanser, all-in-one conditioning and shampooing formula, or general-purpose cleanser. Cleansing formulas are particularly useful in body cleansing processes, especially for the skin and hair. Such processes include applying the cleansing formula to the body or the area to be cleansed (skin or hair), massaging the cleansing formula into the area to be cleansed (or into the hair), and rinsing the cleansing formula off the body. a. Acylglycinate surfactants#

[0039] Acylglycinate surfactants include those of formula (X): n (X)

[0040] wherein R is an alkyl chain of 8 to 16 carbon atoms and M is a cation. Cations include alkali metal ions, such as sodium or potassium, ammonium ions, or alkanolammonium ions, such as monoethanolammonium or triethanolammonium ions. Non-limiting examples of acylglycinates include sodium cocoylglycinate, sodium lauroylglycinate, sodium myristoylglycinate, potassium lauroylglycinate, potassium cocoylglycinate, or mixtures thereof. In a preferred embodiment, one or more acylisethionate surfactants are sodium cocoylglycinate.

[0041] In various embodiments, the only anionic surfactants in the cleaning composition in the form of a stable foam are one or more acylglycinate surfactants. Thus, the cleaning composition in the form of a stable foam may be free or substantially free of anionic surfactants other than one or more acylisethionate surfactants.

[0042] In some embodiments, the stable foam cleaning composition includes one or more acylisethionate surfactants selected from sodium cocoylglycinate, potassium cocoylglycinate, or a mixture thereof. In other embodiments, the stable foam cleaning composition includes sodium cocoylglycinate and is preferably free or substantially free of anionic surfactants other than acylglycinate surfactants; even more preferably, the only anionic surfactant in the stable foam cleaning composition is sodium cocoylglycinate.

[0043] Cleaning compositions in stable foam form typically include about 5 to about 45% by weight of one or more acylglycinate surfactants, relative to a total weight of the cleaning composition not transformed into foam. In other embodiments, the cleaning compositions in the form of stable foam include from about 8 to about 45% by weight, from about 10 to about 45% by weight, from about 12 to about 45% by weight, from about 5 to about 40% by weight, from about 8 to about 40% by weight, from about 10 to about 40% by weight, from about 12 to about 40% by weight, from about 5 to about 36% by weight, from about 8 to about 36% by weight, from about 10 to about 36% by weight, or from about 12 to about 36% by weight, relative to a total weight of the cleaning composition not transformed into foam.In still other embodiments, the cleaning composition in stable foam form includes approximately 8 to approximately 25% by weight, approximately 10 to approximately 25% by weight, approximately 12 to approximately 25% by weight, approximately 8 to approximately 20% by weight, approximately 10 to approximately 20% by weight, approximately 12 to approximately 20% by weight, approximately 8 to approximately 18% by weight, approximately 10 to approximately 18% by weight, or approximately 12 to approximately 18% by weight of one or more acylglycinate surfactants, relative to the total weight of the cleaning composition not transformed into foam.

[0044] In various embodiments, the cleaning compositions in the form of a stable foam include one or more acylglycinate surfactants (for example, as mentioned above) and optionally further include one or more additional anionic surfactants, other than one or more acylglycinate surfactants. Non-limiting examples of anionic surfactants other than acylglycinate surfactants include sulfate-based surfactants, acylisethionate surfactants, acylated amino acid-type surfactants other than acylglycinate surfactants (such as acyltaurate surfactants, acylglutamate surfactants, and acylsarcosinate surfactants), alkylsulfonates, alkyl sulfosuccinates, alkyl sulfoacetates, alkoxylated monoacids, their salts, and mixtures thereof. It should be noted that acylglycinate surfactants are a type of surfactant based on acylated amino acids.

[0045] In a preferred embodiment, when the stable foam cleaning composition includes one or more additional anionic surfactants in addition to one or more acylisethionate surfactants, the one or more additional anionic surfactants are preferably not sulfate-based surfactants, for example, sodium lauryl sulfate (SLS), sodium dodecyl sulfate (SDS), or a mixture thereof. The stable foam cleaning compositions may be free or substantially free of sulfate-based surfactants, for example, free or substantially free of sodium lauryl sulfate (SLS), sodium dodecyl sulfate (SDS), or a mixture thereof.

[0046] In various embodiments, when the stable foam cleaning composition includes one or more additional anionic surfactants in addition to one or more acylisethionate surfactants, the total amount of the one or more acylisethionate surfactants is greater than the total combined amount of all the additional anionic surfactants in the stable foam cleaning composition. For example, the total weight percentage of the one or more acylglycinate surfactants in the stable foam cleaning composition may be at least twice as high as the total combined weight percentage of all the additional anionic surfactants in the stable foam cleaning composition.Preferably, the total weight percentage of one or more acylglycinate surfactants in the cleansing composition in stable foam form is at least 3 times higher, at least 4 times higher, at least 5 times higher, at least 8 times higher, or at least 10 times higher than the total combined weight percentage of all additional anionic surfactants in the cleansing composition in stable foam form.In this sense, the weight ratio of the total quantity of one or more acylglycinate surfactants to the total combined quantity of all additional anionic surfactants can be from approximately 2:1 to approximately 50:1, from approximately 2:1 to approximately 40:1, from approximately 2:1 to approximately 25:1, from approximately 2:1 to approximately 20:1, from approximately 2:1 to approximately 15:1, from approximately 2:1 to approximately 10:1, from approximately 2:1 to approximately 8:1, from approximately 3:1 to approximately 50:1, from approximately 3:1 to approximately 40:1, from approximately 3:1 to approximately 25:1, from approximately 3:1 to approximately 20:1, from approximately 3:1 to approximately 15:1, from approximately 3:1 to approximately 10:1, from approximately 3:1 to about 8:1, from about 5:1 to about 50:1, from about 5:1 to about 40:1, from about 5:1 to about 25:1, from about 5:1 to about 20:1, from about 5:1 to about 15:1, or from about 5:1 to about 10:1. Additional anionic surfactants

[0047] As used herein, the expression "additional anionic surfactants" is used generally to refer to anionic surfactants other than acylglycinate surfactants. In various embodiments, additional anionic surfactants (anionic surfactants other than one or more acylglycinate surfactants) may be included in the cleaning composition in the form of a stable foam. In other embodiments, additional anionic surfactants (anionic surfactants other than one or more acylglycinate surfactants) may be excluded from the cleaning composition in the form of a stable foam. Consequently, cleaning compositions in the form of a stable foam, in some embodiments, may be free or substantially free of one or more (or all) additional anionic surfactants. (anionic surfactants other than one or more acylglycinate surfactants), including those shown below.

[0048] Non-limiting examples of anionic surfactants other than acylglycinate surfactants include sulfate-based surfactants, acylisethionate surfactants, acylated amino acid-type surfactants other than acylglycinate surfactants (such as acyltaurate surfactants, acylglutamate surfactants and acylsarcosinate surfactants), alkylsulfonates, alkyl sulfosuccinates, alkyl sulfoacetates, alkoxylated monoacids, their salts, and mixtures thereof. i. Sulfate-based surfactants#

[0122] (i) Antioxidants

[0123] Examples of antioxidants include tocopherols (e.g., da-tocopherol, d-[3-tocopherol, dy-tocopherol, d-delta-tocopherol), tocotrienols (e.g., da-tocotrienol, d-[3-tocotrienol, dy-tocotrienol, d-delta-tocotrienol), and vitamin E (α-tocopherol acetate). These compounds may be isolated from natural sources, prepared by synthetic means, or combinations thereof. Vitamin E preparations enriched in tocotrienol may be obtained by fractionating vitamin E preparations to remove some of the tocopherols and recover a preparation with a higher tocotrienol concentration. Useful tocotrienols are natural products isolated, for example, from wheat germ oil, cereals or palm oil using high-performance liquid chromatography, or isolated by alcohol extraction and / or molecular distillation from barley, distillers' grains or oats.As used here, the term "tocotrienols" includes both tocotrienol-rich fractions obtained from these natural products and pure compounds.

[0130] The antioxidant can be an anthocyanin. Anthocyanins and their derivatives are antioxidants. Anthocyanins encompass a class of flavonoid compounds, which are naturally occurring water-soluble compounds responsible for the red, purple, and blue colors of many fruits, vegetables, grains, and flowers. In addition, anthocyanins are collagenase inhibitors. Inhibition of collagenase contributes to the prevention and reduction of wrinkles, increased skin elasticity, etc., which are caused by a reduction in dermal collagen. Anthocyanins can be obtained from any portion of various plant sources, such as the fruit, flower, stem, leaves, root, and bark. or the seeds. A specialist in the field will understand that certain parts of the plant may contain naturally higher levels of anthocyanins, and that, therefore, these parts are used to obtain the desired anthocyanins. In some cases, the antioxidants may include one or more betacyanins. Betacyanins, like anthocyanins, can come from natural sources and are antioxidants.

The processes typically involve applying the stable foam cleansing composition to the hair or skin. The stable foam cleansing compositions can be massaged or spread onto the hair or skin and then rinsed from the hair or skin. In a preferred embodiment, the stable foam cleansing composition is useful as a skin cleanser, for example, a facial cleanser. EXAMPLES

[0229] Various changes can be made to the compositions and processes described above without departing from the scope of the invention. Therefore, it is anticipated that any Disclosure contained in the description above and in the examples given below shall be interpreted in an illustrative and not limiting sense. Example 1

[0237] 2 Measured at 25 °C with a DHR-2 rheometer, shear rate 1 s1.

[0238] The data show that when the specific gravity of the cleaning composition is greater than approximately 0.83, the cleaning composition in foam form is not stable, even if high amounts of thickening polymer (acrylate copolymer) were included in the compositions. This is illustrated by the results obtained with the comparative compositions. Comparative composition C-6 also shows that when the amount of the nonionic emulsifier having an HLB of approximately 6 or less is greater than approximately 6 or approximately 7% by weight, the cleaning composition in foam form is not stable. Comparative composition C-7 shows that when the total amount of magnesium salts is greater than approximately 2% by weight, the cleaning composition in foam form is not stable.

[0239] The data in Example 1 and Example 2 illustrate the inventors' surprising discovery that glycinate surfactants interact uniquely with magnesium salts to thicken and stabilize cleaning compositions. The amount of magnesium salts must be from about 0.5 to about 2% by weight to achieve the unexpected effects. In addition, the inventors discovered that nonionic emulsifiers with an HLB of about 6 or less must be present in an amount of about 3 to about 7% by weight to achieve the unexpected effects. The combination and amounts of these components contribute to a specific gravity of about 0.6 to about 0.83, which, surprisingly, the inventors claim is necessary to ensure stability.

[0240] The preceding disclosure illustrates and describes embodiments of the invention. The disclosure shows and describes only preferred embodiments, but it is understood that the invention is usable in various other combinations, modifications, and environments, and that it may undergo changes or modifications in the scope of the inventive concepts as expressed herein, depending on the teachings above and / or the skills or knowledge of the relevant art. The embodiments described herein are further intended to explain the best known embodiments of the applicant and to enable others skilled in the art to use the disclosure.

[0241] As used herein, the terms "comprising," "having," and "including" (or "comprise," "having," and "include") are used in their broad, non-limiting sense. The expression "consisting essentially of" restricts the scope of a claim to the specified materials or steps and to those that do not materially affect the basic and innovative features of the claimed invention.

[0242] The surfactants referred to throughout the disclosure may include those having a counterion, such as an alkali metal, alkaline earth metal, or ammonium counterion. This list of counterions, however, is not exhaustive.

[0243] The expression "one or more" means "at least one" and therefore includes individual components as well as mixtures / combinations.

[0244] The term “plurality” means “more than one” or “two or more”.

[0245] Except in operational examples, or unless otherwise indicated, all numbers expressing quantities of ingredients and / or reaction conditions may in all cases be modified by the term "approximately", meaning to within + / - 5% of the stated number. For example, a quantity "of approximately 1 by weight" may include a quantity as low as 0.95% by weight or as high as 1.05. Similarly, a quantity "of approximately 50" may include a quantity as low as 47.5% by weight and as high as 52.5% by weight.

[0246] Some of the various ingredient categories identified for cleansing compositions may overlap. In cases where an overlap may exist and the composition / product includes two (or more than two) overlapping components, an overlapping component shall not represent more than one claimed component. For example, a fatty acid may be considered both as a "fatty compound" and separately as a "nonionic surfactant" or a "nonionic emulsifier." If a claimed composition / product refers to a fatty compound and separately to a nonionic surfactant, a single fatty acid in a composition shall serve only as a fatty compound or only as a nonionic surfactant. A single fatty acid may not simultaneously serve as both a fatty compound and a nonionic surfactant.

[0247] All percentages, parts and ratios herein are based on the total weight of the compositions of the present invention, unless otherwise stated.

[0248] All ranges and values ​​disclosed herein are inclusive and combinable. For example, any value or point described herein that falls within a range described herein can serve as a minimum or maximum value for deducing a subrange, and so on. Furthermore, all ranges provided are intended to include each specific range within the given ranges, and a combination of intermediate subranges within the given ranges. Thus, a range of 1 to 5 specifically includes 1, 2, 3, 4, and 5, as well as subranges such as 2 to 5, 3 to 5, 2 to 3, 2 to 4, 1 to 4, and so on.

[0249] The term "surfactant" (or "emulsifier") includes the salts of the surfactant, to the extent that they exist, even if not explicitly stated. In other words, whenever the disclosure refers to a surfactant (or surfactants), it is intended that the salts of the surfactants are also encompassed to the extent that they exist, even if the patent memorandum may not specifically refer to a salt (or may not refer to a salt in all instances throughout the disclosure), for example, by using a phrase such as "one of its salts" or "their salts." Sodium and potassium are common cations that form salts with surfactants. However, additional cations such as ammonium ions, or alkanoammonium ions such as monoethanolammonium or triethanolammonium ions, may also form salts of surfactants.

[0250] All components positively presented in this disclosure may be negatively excluded from the claims and the compositions and processes described throughout this disclosure. In other words, the cleaning compositions of this disclosure may be free or substantially free of one or more of the components positively presented in this disclosure for possible inclusion in the cleaning compositions.

[0251] The expression "substantially free" or "essentially free" as used herein means that the specific material may be present in small quantities that do not materially affect the basic and innovative features of the claimed invention. For example, less than 1% by weight of a specific material may be added to a composition, relative to the total weight of the composition (provided that an amount less than 1% by weight does not materially affect the basic and innovative features of the claimed invention). Similarly, where a composition is essentially free of a particular element, the composition may include 1% by weight or less, 0.5% by weight or less, 0.1% by weight or less, 0.05% by weight or less, 0.01% by weight or less, or no amount of the specified material.For example, if a composition is "substantially free" or "essentially free" of ethanol, the composition may optionally include ethanol in an amount of up to 1% by weight, relative to the total weight of the composition, provided that 1% by weight does not materially affect the basic and innovative characteristics of the composition. In addition, the composition may optionally include 0.5% by weight or less, 0.1% by weight or less, 0.05% by weight or less, 0.01% by weight or less, or no ethanol.< / gfmi>
