[0014] Foaming Cleanser

[0015] The disclosure provides, in various embodiments, a foaming cleanser comprises (a) at least one fatty alcohol; (b) at least one amphoteric surfactant; (c) at least one anionic surfactant; and (d) water; wherein the foaming cleanser excludes PEG based ingredients. This formulation provides a skin-friendly cleansing solution that avoids potential irritants associated with PEG based ingredients. In some embodiments, the foaming cleanser excludes PEG / PEO polymeric thickeners, parabens, and combinations thereof. This exclusion further enhances the safety profile of the cleanser, particularly for, but not limited to, sensitive skin. In some embodiments, the foaming cleanser excludes PEG- 150 pentaerythrityl tetrastearate, PEG-6 caprylic / capric glycerides, or a combination thereof, reducing the risk of adverse skin reactions. In some embodiments, the at least one fatty alcohol is present from about 0.05% to about 2% by weight, based on the weight of the composition, providing optimal moisturizing properties without excessive greasiness.

[0016] In some embodiments, the at least one fatty alcohol is present from about 0.05% to about 1% by weight, based on the weight of the composition, ensuring effective skin conditioning. In some embodiments, the fatty alcohol is present in a total amount that does not exceed 2% by weight, based on the weight of the composition. In some embodiments, the at least one fatty alcohol is characterized by a feature selected from the group consisting of (i) being liquid or semi-waxy at room temperature and containing carbon chain length from 6 up to 22; (ii) being liquid or semi-waxy at room temperature and containing carbon chain length from 6 up to 18; (iii) being liquid or semi-waxy at room temperature and containing carbon chain length from 8 up to 10; (iv) being liquid or semi-waxy at room temperature and containing carbon chain length from 10 up to 16; (v) being selected from linear or branched, saturated or unsaturated, with hydroxyl group on terminal position or non-terminal position; (vi) being selected from the group consisting of hexyldecanol, oleoyl alcohol, lauryl alcohol, myristyl alcohol, cetyl alcohol, decanol, butyloctanol, hexydecanol, palmitoleyl alcohol, and combinations thereof; and (vii) combinations thereof, providing versatility in formulation to achieve desired sensory and functional attributes.

[0017] In some embodiments, the at least one amphoteric surfactant is characterized by a feature selected from the group consisting of (i) present from about 1% to about 15% by weight, based on the weight of the composition; (ii) present from about 3% to about 10% by weight, based 54909-6135-9257, v. 2Attorney Docket No. OA25086-WO-PCT:RHZ / TN / 31710-7187on the weight of the composition; (iii) selected from the group consisting of cocoamidopropyl hydroxysultaine, coco betaine, cocoamidopropyl betaine, and combinations thereof; and (iv) combinations thereof, ensuring mild and effective cleansing action.

[0018] In some embodiments, the at least one anionic surfactant comprises sodium methyl cocoyl taurate.

[0019] In some embodiments, the foaming cleanser further comprises an additional ingredient selected from the group consisting of niacinamide, phenoxyethanol, sodium hyaluronate, glycerin, sodium chloride, sodium benzoate, sodium lauroyl lactylate (and) ceramide NP (and) ceramide AP (and) phytosphingosine (and) cholesterol (and) xanthan gum (and) carbomer (and) ceramide EOP, propanediol, tetrasodium glutamate diacetate, citric acid, and combinations thereof, which can enhance the overall skin benefits of the cleanser.

[0020] The foaming cleanser is shelf stable and stable on application, demonstrating a viscosity of about 15-40 UD (Viscosity Rheomat M3 Spindle), or from about 20-30 UD, and a pH about 4.5 to about 6.5, or about pH 5. The foaming cleanser may be essentially free or devoid of added PEG-type, PEG / PEO polymeric thickeners.

[0021] The present invention provides a new type of alternative natural thickeners to replace PEG based ingredients, particularly but not limited to PEG / PEO thickeners, in cleansing products. During the exploration of PEG alternatives, it was unexpectedly discovered that intermediate to long chain fatty alcohols, which are typically liquid or semi-waxy at room temperature and feature carbon chain lengths from 8 up to 22, can effectively thicken the formulation. These fatty alcohols can be linear or branched, saturated or unsaturated, and may have hydroxyl groups in either terminal or non-terminal positions. Traditionally, fatty alcohols are recognized for their cosmetic properties, including emollient, hydrating, softening, and protective effects. While long chain fatty alcohols (C22 or greater) are often used to impart a waxy texture in hair and skincare products due to their high melting points, it was surprising to find that intermediate chain fatty alcohols (C8 to C22) also serve as effective thickeners in cleansing compositions. These fatty alcohols, although previously known as emollients in facial cleansers, were not recognized for their thickening ability. However, they have been found to significantly enhance the viscosity and sensoriality of the formulation, providing a viable substitute for PEG, while maintaining or even improving foam characteristics.64909-6135-9257, v. 2Attorney Docket No. OA25086-WO-PCT:RHZ / TN / 31710-7187

[0022] In some embodiments, the foaming cleanser excludes PEG / PEO ingredients and polymeric thickeners, parabens, and combinations thereof. This exclusion further enhances the safety profile of the cleanser, reducing the risk of adverse skin reactions. The inventive composition demonstrates performance that is at least as effective as, if not improved over, commercial benchmarks and comparatives containing PEG ingredients, providing moisturizing properties without excessive greasiness, demonstrating foaming that is not compromised even in the absence of PEG / PEO, balancing cleansing efficacy with skin hydration, providing versatility in formulation to achieve desired sensory and functional attributes, and enhancing the formulation's safety and appeal for consumers seeking cleaner beauty products, optimizing foaming and cleansing performance.

[0023] Exclusion of PEG-Based Ingredients

[0024] A notable feature of the foaming cleanser formulation is the exclusion of PEG-based ingredients, including PEG / PEO polymeric thickeners and parabens. This exclusion addresses concerns related to potential skin irritation and environmental safety, aligning the product with current consumer preferences for cleaner and more natural formulations.

[0025] The described foaming cleanser is designed to deliver effective cleansing while maintaining the skin's natural moisture balance and providing a pleasing sensory experience. By selecting ingredients that are both effective and gentle, the formulation caters to a wide range of skin types and consumer needs.

[0036] Fatty Alcohols

[0037] The foaming cleanser includes at least one fatty alcohol, in particular medium chain length fatty alcohol.

[0038] Fatty alcohols used in the cleanser can vary widely, providing flexibility in formulation. These alcohols may be selected from those that are liquid or semi-waxy at room temperature, and they typically contain carbon chain lengths ranging from 6 to 22. This category includes both linear and branched structures, saturated or unsaturated forms, and may feature hydroxyl groups in either terminal or non-terminal positions.

[0039] Specific examples of fatty alcohols include hexyldecanol, oleoyl alcohol, lauryl alcohol, myristyl alcohol, cetyl alcohol, decanol, butyloctanol, hexydecanol, and palmitoleyl alcohol. Combinations of these alcohols can be used to achieve desired properties in the foaming cleanser.

[0040] In particular embodiments, the fatty alcohol is selected from hexyldecanol, oleoyl alcohol, lauryl alcohol, myristyl alcohol, cetyl alcohol, and combinations thereof. Specific blends, such as a combination of lauryl alcohol, myristyl alcohol, and cetyl alcohol may be selected. The formulation may consist of single alcohols like hexyldecanol or oleoyl alcohol, or it may comprise a blend of these with other fatty alcohols.

[0041] In various embodiments, the amount of the at least one fatty alcohol is from about 0.05% to about 2%, or from about 0.05% to about 1%, or from about 0.05% to about 0.8%, or from about 0.05% to about 0.6%, or from about 0.05% to about 0.5%, or from about 0.1% to about 1.5%, or from about 0.1% to about 1%, or from about 0.2% to about 0.8%, or any suitable combination, sub-combination, range, or sub-range thereof by weight, based on the weight of the foaming cleanser.

[0208] Although the optional additives are given as examples, it will be appreciated that other optional components compatible with cosmetic applications known in the art may be used that 384909-6135-9257, v. 2Attorney Docket No. OA25086-WO-PCT:RHZ / TN / 31710-7187are suitable. It will be appreciated by a skilled artisan that any optional additives are present only to the extent and in amounts that do not materially adversely affect the basic and novel characteristic(s) of the claimed disclosure. Thus, In some embodiments, that include optional additives, such optional additives will not materially adversely affect the foaming cleanser.

[0209] Further, any one or more (or all) of additional or optional additives and actives may be excluded from the composition. In other words, the composition may be free or essentially free of any or all of the additional or optional additives, actives, and other ingredients disclosed herein.

[0210] More generally, it will be appreciated by a skilled artisan that any solvents, humectants, preservatives or other additives are present only to the extent and in amounts that do not materially adversely affect the basic and novel characteristic(s) of the claimed invention.

[0211] Examples

[0212] EXAMPLE 1: Compositions:

[0213] Various representative embodiments of the inventive and comparative compositions are exemplified herein.

[0214] Table 2: Inventive and Comparative Compositions

[0215] The table below provides compositional ingredients for each of compositions that include a Base (no thickener / Fatty alcohol - common to the inventive and comparative compositions), Comparative Composition (PEG thickener), and Inventive Compositions (including Fatty alcohol Hexyldecanol @ 0.1%, Fatty alcohol Hexyldecanol @0.3%, Fatty alcohol Oleyl @ 0.1%, Fatty alcohol Oleyl @0.3%, Fatty alcohol Lauryl / Mixed @ 0.1%, Fatty alcohol Lauryl / Mixed @0.3%), all amounts by weight, based on the weight of the composition.394909-6135-9257, v. 2Atorney Docket No. OA25086-WO-PCT:RHZ / TN / 31710-7187

[0216] As shown above, the inventive compositions, particularly those having at least 0.3% faty alcohol, perform at least comparatively, if not improved, relative to the PEG-Containing comparative composition sharing the same base with the inventive composition.

[0217] In stability tests, the inventive compositions demonstrate good to excellent overall stability, even after exposure to high heat for up to two months. Note, the Comparative comparison, which lacks the taurate anionic surfactant, demonstrates foaming volume and bubble size properties that are different from the inventive embodiments, with comparable stability.

[0218] EXAMPLE 1: Commercial Benchmark:

[0219] Table 2: Commercial Benchmark Composition404909-6135-9257, v. 2Attorney Docket No. OA25086-WO-PCT:RHZ / TN / 31710-7187

[0220] As shown in Tables 1 and 2, above, the inventive compositions, particularly those having at least 0.3% fatty alcohol, perform at least comparatively, if not improved relative to the benchmark composition which is thickened with PEG-thickeners in a generally similar base.

[0221] 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.

[0222] 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.

[0223] 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.

[0224] ‘ ‘At least one,” as used herein, means one or more and thus includes individual components as well as mixtures / combinations.414909-6135-9257, v. 2Attorney Docket No. OA25086-WO-PCT:RHZ / TN / 31710-7187

[0225] 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.”

[0226] ‘ ‘Free” and “devoid” and “exclude” or “excluded” each indicates that no reliably measurable excluded material, for example, an excluded thickener or excluded sulfate surfactant or other excluded material as described herein, is present in the composition. The term “essentially free” means that, while it is preferred that no excluded material is present in the composition, it is possible to have very small amounts of the excluded material in the composition of the invention, provided that these amounts do not materially affect the advantageous properties of the composition. In particular, “essentially free” means that excluded material can be present in the 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, or at 0%, based on the total weight of the composition.

[0227] In accordance with the various embodiments, it is contemplated that some or all of following ingredients may be excluded from the 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), salicylic acid, capryloyl salicylic acid, beta hydroxybutanoic acid, propionic acid, beta-hydroxy beata-methylbutyric acid, carnitine tropic acid, and trethocanic acid; alkyl polyglucosides selected from424909-6135-9257, v. 2Attorney Docket No. OA25086-WO-PCT:RHZ / TN / 31710-7187the 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 CIO- 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- CIO 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 polygly cosides 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, polylysine, microplastics, synthetic dyes, gelling agents, and combinations thereof.

[0228] ‘ ‘Excluded polymeric thickeners” means and refers to thickeners that have not been added as a component in the composition or that may be excluded in some embodiments. Thus, in some embodiments, the composition is essentially free, free or devoid of one or more of PEG / PEO polymeric thickeners, nature based thickeners, and synthetic thickeners. In some embodiments, the composition is essentially free of or excludes PEG-type polymeric thickeners selected from PEG-150 pentaerythrityl tetrastearate, PEG-120 thickeners, PEG-150 thickeners, PEG-80 glyceryl tallow ester, PEG-8 PPG (polypropylene glycol) -3 diisostearate, PEG-200 hydrogenated glyceryl palmitate, PEG-n(n=6, 8, 12) beeswax, PEG-4 isostearate, PEG-n(n=3, 4, 8, 150) distearate PEG-n(n=28, 200) glyceryl tallow ester, PEG-7 hydrogenated castor oil, PEG-40 jojoba oil, PEG-120 methyl glucose dioleate, PEG-150 pentaerythritol stearate, PEG-55 propylene glycol oleate, PEG- 160 sorbitan triisostearate, SMDI copolymer (polyethylene glycol -150 / decyl / methacrylate copolymer), PEG-150 / stearyl / SMDI copolymer, PEG-90, and 434909-6135-9257, v. 2Attorney Docket No. OA25086-WO-PCT:RHZ / TN / 31710-7187combinations thereof.

[0229] “ Sulfate surfactant-free” means that excluded surfactants have not been added as a component. In some particular embodiments, the composition is devoid of sulfate based surfactant. In some embodiments, the composition is devoid of ethylene glycol (PEG) based surfactants. Those of skill in the art will appreciate that a surfactant may be present in a composition via its presence in one or more of the formulation components; thus, In some embodiments, the composition may be “essentially-free” wherein the excluded surfactant is present at a concentration that does not exceed 5% by weight, and in some instances is present not more than 3% by weight, and in some instances is present not more than 1% by weight, based on the weight of the cosmetic composition. In some particular embodiments “sulfate surfactant-free” means that the cosmetic composition is free or devoid specifically of the excluded sulfate surfactant.

[0230] ‘ ‘Petrochemical-free” means that an excluded petrochemical has not been added as a component. Some specific but non-limiting examples of petrochemicals that are lacking from the cosmetic composition include benzalkonium chloride, isododecane, isohexadecane and the like. In some embodiments, the composition is not free from petrochemicals, but is formulated to have an amount of petrochemicals that is at or below the amounts found in similar compositions that are commercially available. The composition may be petrochemical-free.

[0231] “ Silicone-free” means that an excluded silicones has not been added as a component. In some embodiments, a composition is devoid of silicones. Some specific but non-limiting examples of silicones that are lacking from the cosmetic composition includes, but is not limited to, silicone polymers, for example selected from dimethicone, cyclopentasiloxane, and other silicone oils, and silicone elastomers. The composition may be silicone-free.

[0232] Other than in the operating examples, or where otherwise indicated, all numbers expressing quantities of ingredients and / or reaction conditions may be understood as being 454909-6135-9257, v. 2Attorney Docket No. OA25086-WO-PCT:RHZ / TN / 31710-7187modified 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%).

[0233] 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.

[0234] 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.

[0235] 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.

[0236] 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.464909-6135-9257, v. 2
