This invention relates to a foaming cleansing composition.
Conventional cleansing systems relying on sulfate surfactants and amphoteric surfactants to build viscosity via surfactant interaction. Such combinations of ingredients provide entangled elongated type micelles that provide favorable surfactant ratio, pH condition, and levels of electrolytes and salt to accomplish cleansing. There are challenges in replacing sulfate surfactants with more nature-based surfactants such as amino acid surfactant and other biosurfactants such as glycolipids. These nature-based surfactants are believed to have size features that are less favorable for micelle formation and may be less salt-responsive. For these reasons, nature-based systems that don't rely on sulfate surfactants require the inclusion of thickeners, for example PEG-type polymeric thickeners, and a multiplicity of surfactants. These formulations are less desirable at least for the reason that the compositions have undesirable sensory properties and can be thick and gel like rather than smooth liquidous. In addition, such formulations can be disadvantageous due to inclusion of synthetic, non-biological or nature based ingredients, including ingredients with believed toxicity.
The inventors have formulated an innovative technology that overcomes the shortcomings of the prior art to provide high performing cleansers with desirable foaming and cleansing properties without use of sulfate surfactants and added thickeners, particularly PEG-type polymeric thickeners. It is posited that the unique blend of surfactants in the foaming cleansing composition provide entangled elongated type micelles to accomplish cleansing and provide foaming without the disadvantages of the art.

This Comparative Composition includes, in addition to amphoteric surfactants cocamidopropyl betaine and cocamidopropyl hydroxysultaine, seven additional non-amphoteric surfactants, including coco-glucoside, sodium lauroyl methyl isethionate, sodium methyl oleoyl taurate, glycolipids (with carboxyl), linoleic acid (with carboxyl), linolenic acid (with carboxyl), lauryl glucoside. Notably, three of these surfactants have carboxyl groups.
Commercial Example; COMP #3: Aqua, Glycerin, Cocamidopropyl Betaine, Coco-glucoside, Propanediol, Sodium Lauroyl Methyl Isethionate, Cocamidopropyl Hydroxysultaine, Sodium Methyl Oleoyl Taurate, Acrylates Crosspolymer-4, Butylene Glycol, Enantia Chlorantha Bark Extract, Oryza Sativa Bran Extract (Bran), Olea Europaea (Olive) Leaf Extract, Camellia Sinensis Leaf Extract, Aspalathus Linearis Extract, Polygonum Cuspidatum Root Extract, Olea Europaea Fruit Oil, Pseudozyma Epicola/Olive Fruit Oil Ferment Filtrate (Filtered, Fermented), Hydrogenated Ethylhexyl Olivate (Hydrogenated), Cocos Nucifera Fruit Extract, Mel Extract, Hydrogenated Olive Oil Unsaponifiables (Hydrogenated), Boswellia Serrata Resin Extract, Sodium Hydroxypropylphosphate Decylglucoside Crosspolymer, Glycol Distearate, Lauryl Glucoside, Sodium Chloride, Glycolipids, Sodium Stearoyl Lactylate, Salicylic Acid, Niacinamide, Mica, Squalane, Tin Oxide, Oleanolic Acid, Polydextrose, Dextrin, Amylopectin, Tetrapeptide-14, Sodium Hydroxide, Citric Acid, Sodium Benzoate, Phenoxyethanol, Potassium Sorbate, Parfum, Titanium Dioxide, Cl 75470.
For foaming analysis, a Dynamic foam analyzer (Kruss DFA100) was used. Each evaluated composition was diluted at 25× to evaluate foaming performance. Foam was generated via mechanical stirring in first 20 seconds and foam stability was monitored in following 180 seconds. The results are shown in Table 4, below.
Foaming Analysis Performance: The inventive composition, INV 4, demonstrated greater foam height compared to both comparative benchmark formulations. Specifically regarding COMP #1, the comparative composition demonstrated similar initial foam density/bubble size and height relative to the INV 4 composition but the foam decayed faster (that is, the bubbles merged and became larger with fewer bubbles) and the foam height declined over time evidencing instability of the foam.
Each of the compositions including INV 4 and COMP #2 (Benchmark #2) and COMP #2 (Benchmark #2) were evaluated for viscosity. The viscosity of COMP #2 is much higher than any of the inventives, wherein the viscosity of COMP #2 is about 75-80 M3, in comparison, the viscosity of INV 4 is ˜20 M3. Notably, COMP #2 has a gel texture, while INV 4, representative of all of the inventives herein, is a smooth viscous liquid, with no jelly or gel texture. In various embodiments, viscosity of the inventive composition may range from about 20 M3 to about 70 M3, and thus may have a viscosity from about 20 M3, 22, 24, 26, 28, 30, 32, 34, 36, 38, 40, 42, 44, 46, 48, 50, 52, 54, 56, 58, 60, 62, 64, 66, 68 to about 70 M3. Inventive composition embodiments with a higher viscosity include less than 50% fraction of surfactant with carboxyl group/non-amphoteric. Even at higher viscosity, the composition differs from benchmark as being smooth and not in a gel form. Niacinamide is/may be contributing to viscosity reduction.
The results of a study evaluating effect of Varied Surfactants with Carboxyl Group to all Surfactants are shown below in Table 5.
The foregoing demonstrates that suitable viscosity and foaming are achieved when the fraction of surfactant with carboxyl group represents at least 40% or greater of the total amount of non-amphoteric surfactant.
The results of a study evaluating effect of polymer on formulation properties of clarity (visualized with the naked eye), foaming and texture on application (good is creamy, thick and smooth, not gelled) are shown below in Table 6.
The foregoing demonstrates that foaming and texture properties can be accomplished in the absence of added thickeners to achieve a visibly (as observed by the naked eye) clear, good foaming composition with a smooth, rich texture that is not jelly or gel like. It is posited by the inventors, without being bound by theory, that instead of relying on polymer thickener, the inventive composition includes a surfactant system that builds viscosity by self-assembly of surfactant molecules. Via tuning the surfactant ratio, as shown in Example 5, the structure of surfactant aggregates or the curvature of surfactant micelle can be varied to provide non-spherical entangled elongated micelles. Further, inclusion of niacinamide, as noted in Example 4, present in a range from about 0.05% to about 5.0%, by weight of the composition, may influence maintenance of viscosity properties of the composition, and participates in tuning (adjusting) the viscosity to accomplish viscosity in a range from about 20 M3 to about 70 M3.
Inventive composition INV 4 and Comparative composition COMP #1 were tested with clinical subjects to provide evidence of sensory features. The results are shown below in Table 7.
The results demonstrate that the inventive composition performs at least as well as the commercial benchmark and has more desirable foaming and textural/viscosity properties.
While the disclosure has been described with reference to an embodiment, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the scope of the disclosure. In addition, many modifications may be made to adapt a particular situation or material to the teachings of the disclosure without departing from the essential scope thereof. Therefore, it is intended that the disclosure not be limited to the particular embodiment disclosed as the best mode contemplated for carrying out this disclosure, but that the disclosure will include all embodiments falling within the scope of the appended claims.
The articles “a” and “an,” as used herein, mean one or more when applied to any feature in embodiments of the present disclosure described in the specification and claims. The use of “a” and “an” does not limit the meaning to a single feature unless such a limit is specifically stated. The article “the” preceding singular or plural nouns or noun phrases denotes a particular specified feature or particular specified features and may have a singular or plural connotation depending upon the context in which it is used. The adjective “any” means one, some, or all indiscriminately of whatever quantity.
“At least one,” as used herein, means one or more and thus includes individual components as well as mixtures/combinations.
The transitional terms “comprising,” “consisting essentially of” and “consisting of”, when used in the appended claims, in original and amended form, define the claim scope with respect to what unrecited additional claim elements or steps, if any, are excluded from the scope of the claim(s). The term “comprising” is intended to be inclusive or open-ended and does not exclude any additional, unrecited element, method, step or material. The term “consisting of” excludes any element, step or material other than those specified in the claim and, in the latter instance, impurities ordinarily associated with the specified material(s). The term “consisting essentially of” limits the scope of a claim to the specified elements, steps or material(s) and those that do not materially affect the basic and novel characteristic(s) of the claimed disclosure. All materials and methods described herein that embody the present disclosure can, in alternate embodiments, be more specifically defined by any of the transitional terms “comprising,” “consisting essentially of,” and “consisting of.”
In some embodiments, the terms “Exclude,” “Free” and “Essentially Free” mean that no reliably measurable excluded material, typically 0% by weight, based on the total weight of the foaming cleansing composition, or, for example, no amount greater than about 5%, by weight, based on the total weight of the foaming cleansing composition, of any excluded material as described herein, is present in the foaming cleansing composition. The terms “Exclude,” “Free” and “Essentially Free” mean that, while it is preferred that no excluded material is present in the foaming cleansing composition, it is possible to have very small amounts of the excluded material in the foaming cleansing composition of the invention, provided that these amounts do not materially affect the advantageous properties of the foaming cleansing composition. In particular, the terms “Exclude,” “Free” and “Essentially Free” mean that material can be present in the foaming cleansing composition at an amount of less than 5%, or less than 4%, or less than 3%, or less than 2%, or less than 1%, or less than 0.1% by weight, based on the total weight of the foaming cleansing composition. In accordance with the various embodiments, it is contemplated that some or all of following ingredients may be excluded from the foaming cleansing composition according to the invention: alcohols, for example but not limited to, monohydric alcohols; powders comprising Nylon-12, polymethyl methacrylate, polyethylene beads, and powders which are considered microplastics; lactic acid, glycolic acid, tartaric acid, mandelic acid, citric acid, salicylic acid and derivatives thereof (including 5-n-octanoylsalicylic acid, salicylate, sodium salicylate, and willow extract), capryloyl salicylic acid, beta hydroxybutanoic acid, propionic acid, beta-hydroxy beata-methylbutyric acid, carnitine tropic acid, and trethocanic acid; alkyl polyglucosides selected from the group consisting of decyl glucoside, lauryl glucoside, octyl glucoside, coco glucoside, caprylyl/capryl glucoside, and sodium lauryl glucose carboxylate, and combinations thereof; surfactants with a C10-C20 fatty alcohol or acid hydrophobe condensed with from about 2 to about 100 moles of ethylene oxide or propylene oxide per mole of hydrophobe; C2-C10 alkyl phenols condensed with from 2 to 20 moles of alkylene oxide; mono- and di-fatty acid esters of ethylene glycol; fatty acid monoglyceride; sorbitan; mono- and di-C8-C20 fatty acids; polyoxyethylene sorbitan; alkyl polyglycosides and saccharide fatty amides (e.g. methyl gluconamides); alkyl ether sulfate and sulfonates; alkyl sulfates and sulfonates; alkylbenzene sulfonates; alkyl and dialkyl sulfosuccinates; C8-C20 acyl isethionates; C8-C20 alkyl ether phosphates; alkylethercarboxylate, PEG-100 Stearate; PEG-20 Stearate and other esters of Poly(Ethylene Glycol); polyethylene glycol (PEG) surfactants, polypropylene glycol (PPG) surfactants, sulfate surfactants; taurates, for example, taurate surfactants; Sucrose Stearate and other emulsifiers based on sugar esters; Glyceryl Stearate and other glycerol esters; Disodium Ethylene Dicocamide PEG-15 Disulfate; Sodium Steroyl Glutamate and other fatty amides; Steareth-100 and other fatty ethers, cationic surfactants, and other cationic compounds; silicones, such as silicone polymers, silicone elastomers, and silicone oils, for example selected from dimethicone, cyclopentasiloxane, cyclohexasiloxane, and combinations thereof; phthalates, parabens, sulfates, polyquaternium, microplastics, synthetic dyes, gelling agents, and combinations thereof.
Other than in the operating examples, or where otherwise indicated, all numbers expressing quantities of ingredients and/or reaction conditions are to be understood as being modified in all instances by the term “about,” meaning within 10% of the indicated number (e.g., “about 10%” means 9%-11% and “about 2%” means 1.8%-2.2%).
All percentages and ratios are calculated by weight unless otherwise indicated. All percentages are calculated based on the total composition unless otherwise indicated. Generally, unless otherwise expressly stated herein, “weight” or “amount” as used herein with respect to the percent amount of an ingredient refers to the amount of the raw material comprising the ingredient, wherein the raw material may be described herein to comprise less than and up to 100% activity of the ingredient. Therefore, weight percent of an active in a composition is represented as the amount of raw material containing the active that is used, and may or may not reflect the final percentage of the active, wherein the final percentage of the active is dependent on the weight percent of active in the raw material.
All ranges and amounts given herein are intended to include subranges and amounts using any disclosed point as an end point. Thus, a range of “1% to 10%, such as 2% to 8%, such as 3% to 5%,” is intended to encompass ranges of “1% to 8%,” “1% to 5%,” “2% to 10%,” and so on. All numbers, amounts, ranges, etc., are intended to be modified by the term “about,” whether or not so expressly stated. Similarly, a range given of “about 1% to 10%” is intended to have the term “about” modifying both the 1% and the 10% endpoints. Further, it is understood that when an amount of a component is given, it is intended to signify the amount of the active material unless otherwise specifically stated.
Notwithstanding that the numerical ranges and parameters setting forth the broad scope of the disclosure are approximations, unless otherwise indicated the numerical values set forth in the specific examples are reported as precisely as possible. Any numerical value, however, inherently contains certain errors necessarily resulting from the standard deviation found in their respective testing measurements. The example that follows serves to illustrate embodiments of the present disclosure without, however, being limiting in nature.
All publications and patent applications cited in this specification are herein incorporated by reference, and for any and all purposes, as if each individual publication or patent application were specifically and individually indicated to be incorporated by reference. In the event of an inconsistency between the present disclosure and any publications or patent application incorporated herein by reference, the present disclosure controls.
