This invention relates to a nature-based cleansing composition.
Removal of stubborn makeup has always been a challenge and a consumer pain point, particularly for waterproof mascara, long-wear foundation and longer-lasting lip products. Typical “make up removers” and cleansers provide reasonably acceptable pigment removal capacity, but can present challenges with the removal of heavy makeups. A key drawback to existing makeup removal formulations is the inclusion of high amounts of oils which can have a greasy feel and leave skin feeling less fresh and clean than is desired by most consumers. And current cleansers and makeup removers can include alcohols, which can be drying to the skin, and sulfate based surfactants, silicones, and other synthetic components that can be irritating. These ingredients are less attractive to consumers seeking more natural products. Moreover, such makeup removing products do not include foaming which is a feature deemed desirable by most consumers. And many current nature based cleansers often do not have pleasing aesthetics or foaming, do not apply with a thick feel, are not effective removing heavy makeup, and do not come of cleanly after rinsing.
Accordingly, there is a need for a more natural cleansing composition that will provide easy and efficacious makeup removal in a form that is thick with high foam on application and that leaves a clean and refreshing skin feel after use without the use of silicone, alcohols, harsh surfactants and sulfates.

Appropriate fermentation methods are reviewed by D. Haferburg, R. Hommel, R. Claus and H. P. Kleber in Adv. Biochem. Ing./Biotechnol. (1986), 33, 53-90, and by F. Wagner, H. Bock and A. Kretschmar in Fermentation (ed. R. M. Lafferty) (1981), 181-192, Springer Verlag, Vienna.
Use may be made, as rhamnolipid, of the one sold under the name Rheance One by Evonik (INCI name: glycolipids).
In some embodiments the rhamnolipid is present in the foaming cleansing composition at about 5% by weight of the foaming cleansing composition.
The at least one rhamnolipid glycolipid is present in the foaming cleansing composition according to the disclosure from about 0.1% to about 20% by weight, or from about 1% to about 10% by weight, or from about 2% to about 8%, or from about 3% to about 5%, or about 5%, or any suitable combination, sub-combination, range, or sub-range thereof by weight, based on the weight of the foaming cleansing composition.
Thus, one or a combination of rhamnolipid glycolipid may be present, by weight, based on the total weight of the foaming cleansing composition, from about 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, 1.0, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19 to about 20 weight percent, including increments and ranges therein and there between.
In various embodiments, the foaming cleansing composition comprises at least one cationic polymer. In some embodiments, the at least one cationic polymer is nature-based.
Examples of cationic polymers include polysaccharide-based delivery molecules (e.g., chitosan, cyclodextrin, cationic gelatin, cationic dextran, cationic cellulose), cationic peptides and their derivatives (e.g., polylysine, polyornithine), peptide/protein polymers ((e.g., histone, collagen), linear or branched synthetic polymers (e.g., polybrene, polyethyleneimine), natural polymers (e.g., histone, collagen), synthetic dendrimers, cationic thiolated biopolymers (nature-based thiomers or nature-based dendrimers, e.g., chitosan-cysteine, chitosan-thiobutylamidine as well as chitosan-thioglycolic acid).
Examples of nature-based cationic polymers include polysaccharide-based delivery molecules (e.g., chitosan, cyclodextrin, cationic gelatin, cationic dextran, cationic cellulose); cationic peptides and their derivatives (e.g., polylysine, polyornithine), peptide/protein polymers (e.g., histone, collagen); cationic thiolated biopolymers (nature-based thiomers or nature-based dendrimers, e.g., chitosan-cysteine, chitosan-thiobutylamidine, chitosan-thioglycolic acid); or combinations thereof.
In some embodiments, the foaming cleansing composition comprises the at least one nature-based cationic chitosan selected from chitosan oligosaccharide, chitosan (or polymeric chitosan having molecular weight (MW) in a range from about 1 kDa to about 1000 kDa), derivatives of chitosan, including derivatives having enhanced solubility, or combinations thereof.
In various embodiments, chitosan has a MW) in a range from about 1 kDa to about 1000 kDa. In some particular embodiments, chitosan has a MW that is “low” and is in the range from about 1 kDa to about 20 kDa, or from about 10 kDa to about 20 kDa, or from about 12 kDa to about 18 kDa.
In some embodiments, the at least one nature-based cationic polymer is present from about 0.05% to about 2%, or from about 0.2% to about 0.4%, based on the weight of the foaming cleansing composition and comprises chitosan.
Chitosan is a unique polycation because its charge density depends on the degree of acetylation and pH of the media, and its solubility depends on the degree of acetylation and molecular weight. And while chitosan oligomers are soluble over a wide pH range, from acidic to basic (i.e., physiological pH 7.4), chitosan with increasing molecular weight are soluble only in acidic aqueous media even at high deacetylation degrees. This lack of solubility at neutral and basic pH has hindered the use of chitosan in some applications under neutral physiological conditions (i.e., pH 7.4).
The foaming cleansing composition according to the disclosure has a pH in some embodiments that is equal to or less than about pH 6.5. In some embodiments, the foaming cleansing composition has a pH in the range from about pH 4.5 to about 6.5, and more particularly from about pH 6 to 6.5, or from about pH 6.2 to about 6.4.
The at least one nature-based cationic polymer is present in the foaming cleansing composition according to the disclosure from about 0.05% to about 2%, or from about 0.05% to about 1%, or from about 0.1% to about 0.8%, or from about 0.1% to about 0.5%, or from about 0.2% to about 0.4%, or about 0.4%, or about 0.4%, or any suitable combination, sub-combination, range, or sub-range thereof by weight, based on the weight of the foaming cleansing composition.
Thus, one or a combination of polymers may be present, by weight, based on the total weight of the foaming cleansing composition, from about 0.05, 0.06, 0.07, 0.08, 0.90, 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, 1.0, to about 2 weight percent, including increments and ranges therein and there between.

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.
