Description

Title of the invention: WATER-BASED, SMUDGE-RESISTANT, BI-PHASIC MAKE-UP REMOVER DOMAIN

[0001] This invention relates to a natural-based cleansing and makeup removing composition provided in a multi-phase formula that includes two visually distinct phases and provides visually and tactically desirable properties with natural ingredients and provides effective cleansing and makeup removal. BACKGROUND

[0002] Multi-phase liquid cleansing compositions provide excellent aesthetic appearance and are highly appealing to consumers and have been proposed for bath / shower, makeup removal, and hair uses. When allowed to stand, a multi-phase liquid forms two or more visibly distinct phases. When agitated, the cleansing composition forms a single visible phase that separates and reverts to the multiple visibly distinct phases. These compositions often include one or more surfactants and emulsifying polymers, volatile silicone oils, and other similar synthetic compositions, all of which may be irritating to the skin or eyes.

[0003] Consumers seeking less irritating cosmetic products, which are formed from natural components, may seek to avoid cosmetics that include such harsh ingredients. In addition, consumers are increasingly seeking cosmetic products with high sustainability profiles, positive environmental impacts, and compliance with common principles of social responsibility. As a result, cleansing compositions made from chemicals derived from non-animal, non-petrochemical, and renewable sources are widely preferred. To help consumers understand the sustainability profile of a product, industry standards such as ISO 16128 have been developed to allow the natural origin percentages of the product formula to be correctly calculated and indicated on the packaging.Great efforts have been made to develop "highly natural" or "all-natural" cosmetic products, in which more than 99% or all of the carbon atoms in intentionally added ingredients come from natural sources.

[0004] There are several examples in the art of multi-phase cleansing compositions having desirable aesthetics. For example, US20160367959 provides a three-phase cosmetic composition in which one of the liquids comprises a triglyceride oil, another comprises a silicone oil, and a third liquid comprises a polyalkylene glycol. In another example, document EP 1593364 proposes a three-phase cosmetic composition for keratinous fibers, in particular for the hair, which includes a first oily phase, a second phase which contains an ethoxylated fatty acid glyceryl monoester, and a third phase which includes polyols. And in another example, document WO 2014018543 proposes a three-phase cosmetic composition for treating hair which includes an oily phase, a polyol phase, and a silicone phase. Further, in another example, KR20090004048 provides a triphasic cosmetic composition wherein the bottom layer includes 1 to 10 parts by weight of water and 15 to 30 parts by weight of polyoxyethylene palm oil fatty acid glycerin, a middle layer includes 15 to 40 parts by weight of glycerin, and a top layer includes 20 to 50 parts by weight of mineral oil.Additionally, in another example, KR20090004050 provides a four-phase cosmetic composition for cleansing in which the bottom layer includes 5 to 10 parts by weight of water and 15 to 30 parts by weight of polyoxyethyleneglycerol of palm oil fatty acid, the bottom middle layer includes 10 to 20 parts by weight of glycerin, the top middle layer includes 15 to 25 parts by weight of di-methicone, and the top layer includes 10 to 30 parts by weight of mineral oil. These various compositions provide some of the aesthetic benefits sought by consumers in relation to the visual and tactile sensation of multi-phase compositions, but none of them are "highly natural" or "natural".

[0005] It remains technically difficult for a multi-phase liquid cleansing composition to achieve satisfactory phase separation performance and high natural content. Accordingly, there is a need for a cleansing composition, particularly a makeup remover cleanser, that is "highly natural" or "all natural" in a multi-phase liquid form that is aesthetically appealing and exhibits good phase separation performance.

[0006] The present invention overcomes the disadvantages of the art with respect to makeup remover compositions that include ingredients that are primarily natural or based on natural products in an aesthetically pleasing multi-phase formulation with clean phase interfaces and that provides easy makeup removal that is comparable to or improved upon prior art compositions, and that is non-greasy, and includes few or no components that may be irritating to the skin or eyes.

Indeed, the invention as described in the specification has a broader meaning than and is not limited by the exemplary embodiments presented herein, and the terms used herein have their full ordinary meaning.

[0043] It is understood that the foregoing general description and the following detailed description are for illustrative and explanatory purposes only and are not restrictive of the disclosure. DETAILED DESCRIPTION

[0044] In various embodiments, the disclosure provides a cleansing composition for makeup removal that provides an aesthetically pleasing glide-on application and is smear-resistant. In an exemplary embodiment, an inventive makeup removing composition according to the disclosure is in the form of a water-based micellar makeup removing composition comprising at least two surfactants, one or more powdered polysaccharides, and water. The cleansing composition may also include one or more inorganic mineral powders, one or more humectants, one or more silicone-based antifoaming agents, one or more preservatives, and other cosmetically acceptable additives.

[0045] The inventors have surprisingly demonstrated with the cleansing composition that a formulation based on natural products which does not contain harsh surfactants, silicones and thickeners unexpectedly ensures an attractive aesthetic when applied to the skin and exhibits good multi-phase properties. The cleansing composition includes at least three or more visually distinct liquid phases (phase layers). At least one of the three visually distinct phase layers includes at least one cationic surfactant and at least one inorganic salt, this phase layer being present in an amount, by weight of the cleansing composition, in a range of from about 20% to about 80% and contains at least one cosmetically acceptable solvent with a Hilderbrand solubility parameter δ value greater than 15 cal.1 / 3. cm2 / 3.At least one of the three visually distinct phase layers includes at least one cationic surfactant and at least one inorganic salt, wherein the phase layer is present in an amount, by weight of the cleaning composition, in a range of from about 5% to about 50% and has at least one cosmetically acceptable solvent with a Hilderbrand solubility parameter δ value of less than 7.5 cal.1 / 3. cm2 / 3. And at least one of the three visually distinct phase layers is present in an amount, by weight of the cleaning composition, in a range of from about 5% to about 50% and has at least one . cosmetically acceptable solvent with a Hilderbrand solubility parameter δ value between 8 and 10 cal.1 / 3. cm2 / 3. When agitated, the cleansing composition forms a single milky phase which separates after agitation into three or more visibly distinct phases within a maximum period of 24 hours.

[0046] “All natural” as used herein means that all carbon atoms in the in Intentionally added ingredients come from natural sources in accordance with ISO 16128.

[0047] “Cleanser” or “cleaning composition” as used herein means and refers to any cleansing composition used for application to keratinous tissue for one or more of the following purposes: skin cleansing, makeup removal and others.

[0048] “Cosmetically acceptable” as used herein means and refers to a vector which is compatible with any keratinous substrate.

[0049] "Keratinous substrate" and "keratinous tissue", as used herein, mean and are reference to, but not limited to, skin, hair and nails.

[0050] “Multiphasic” as used herein means and refers to compositionswhich include two, three, four or more phases that are separated by a single-phase interface. According to the present disclosure, the cleaning composition includes at least three of these phases. A multi-phase composition requires shaking before application in order to form an extemporaneous emulsion of the multiple phases, in which, after ceasing agitation, the phases rapidly separate and in which, within a period after agitation that may range from a few seconds to a few hours, the phases essentially completely separate and return to their initial state with distinct phase interfaces. The phenomenon of rapid phase separation, or demixing, after their use is one of the desired aesthetic qualities of multi-phase compositions.The inventive composition achieves this property with a high content of natural ingredients and with little or no synthetic components such as synthetic oils, for example, silicone oils, such as cyclopentasiloxane, and without thickeners.

[0051] “Natural or “naturally based” as used herein means and refers to cosmetically acceptable materials and components that are one or more of those obtained directly from nature, are obtained from nature with minimal processing, and are derivatives of materials that are obtained from nature. The cleansing compositions according to the present disclosure are in certain embodiments up to 99.11% natural, or "highly natural."

[0052] “Plant-derived oils” as used herein refer to plant-derived fatty oils that contain one or more fatty chains, and in some embodiments, the fatty chain has a chain length ranging from and including C8 to C24. Thus, in some embodiments, a plant-derived fatty oil may comprise an oil or mixture of oils having a chain length of C8, C9, C10, C11, C12, C13, C14, C15, C16, C17, C18, C19, C20, C21, C22, C23 and C24.

[0053] The terms "free" and "devoid" each indicate that no reliably measurable excluded material, e.g., an excluded volatile silicone oil or an excluded surfactant or other excluded material as described herein, is present in the cleaning composition. The term "substantially free" means that, although it is preferable that no excluded material be present in the cleaning composition, it is possible to have very small amounts of the excluded material in the cleaning composition of the invention, provided that such amounts do not materially affect the beneficial properties of the cleaning composition.In particular, "substantially free" means that the excluded material may be present in the cleaning composition in 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 cleaning composition.

[0054] “Silicone-free” means that the excluded silicones have not been added as as a component. In some embodiments, a composition is free of silicones. Some specific but non-limiting examples of silicones that are absent from the cosmetic cleansing composition include, but are not limited to, silicone polymers, for example selected from dimethicone, cyclopentasiloxane and other silicone oils, and silicone elastomers.

[0055] “Petrochemical-free” means that petrochemicals excluded have not been added as a component. Some specific but non-limiting examples of petrochemicals that are absent from the cosmetic cleansing composition include benzalkonium chloride, isododecane, isohexadecane and the like. In some embodiments, the cleansing composition is not free of petrochemicals, but is formulated to have an amount of petrochemicals that is equal to or less than the amounts found in similar compositions that are commercially available.

[0056] “Surfactant-free” means that the excluded surfactants have not been added in as a component. In some particular embodiments, the cleaning composition is free of surfactants. In some embodiments, the cleaning composition is free of ethylene glycol (PEG)-based surfactant or sulfate / sulfonate-based surfactant, or combinations thereof. Those skilled in the art will understand that a surfactant may be present in a composition via its presence in one or more of the components of the formulation; thus, in some embodiments, the cleaning composition may be “substantially free of surfactant,” with the surfactant present at a concentration that does not exceed 5% by weight. weight, and in some cases is not present at more than 3% by weight, and in some cases is not present at more than 1% by weight, based on the weight of the cosmetic cleansing composition. In some particular embodiments, "surfactant-free" means that the cosmetic cleansing composition is free or specifically lacking in surfactant. Some specific but non-limiting examples of surfactants that are absent from the cleansing composition include those with a C10-C20 alcohol or fatty acid hydrophobe condensed with about 2 to about 100 moles of ethylene oxide or propylene oxide per mole of hydrophobe; C2-C10 alkylphenols condensed with 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; alkylpolyglycosides and fatty amides of saccharides (e.g.methyl glu-conamides); alkyl ether sulfate and sulfonates; alkyl sulfates and sulfonates; alkylbenzene sulfonates; alkyl and dialkyl sulfosuccinates; C8-C20 acyl isethionates; C8-C20 alkyl ether phosphates; alkyl ether carboxylate.

[0057] The term "skin" as used herein refers to keratin-containing skin materials, such as facial and body skin, scalp, eyebrows, and lips.

[0058] The definition and determination of the Hilderbrand solubility parameter for a liquid was previously disclosed by C.D. Hilderbrand in his article entitled "Using Solubility Parameters in Cosmetics Formulation" J. Soc. Cosmet. Chem, 36, 319-333 (September / October 1985). Phases of multiphasic composition

[0059] The cleaning composition includes at least two or more visually distinct liquid phases (phase layers). In some embodiments, the cleaning composition includes two visually distinct phase layers. In some embodiments, the cleaning composition includes more than two visually distinct phase layers, e.g., four or more.

The at least one cationic surfactant is an amino acid-based cationic surfactant that may be selected from an ethyl lauroyl arginate derivative or salt thereof, and ethyl cocoyl arginate or salt thereof (ethyl cocoyl arginate PCA). The first visually distinct phase layer may be present at about 50% to about 95% and the second visually distinct phase layer may be present at about 5% to about 50%, by weight, based on the total weight of the cleaning composition.

In some other examples, the amino acid-based cationic surfactant is selected from the group consisting of lysine-based cationic surfactants. Examples of amino acid-based cationic surfactants can be found in the literature such as Tripathy, Divya, Mishra, Anuradha, Clark, James Hanley orcid.org / 0000-0002-5860-et al (2018) Synthesis, chemistry, physicochemical properties and industrial applications of amino acid surfactants: A review. Comptes Rendus Chimie, pp. 112-130.Reference may be made to some commercial examples of amino acid-based surfactants, which include AMINAT-G (TM) from Vedeqsa, and CAE (TM) from Ajinomoto.

[0064] The amount of the at least one cationic surfactant that is an amino acid-based cationic surfactant present in the cleaning composition is in a range of about 0.01% to about 5%, or about 0.03% to about 1%, or about 0.02% to about 2%, or about 0.05% to about 1% by weight, or about 0.08% to about 1.5%, or about 0.1% to about 0.5%, or about 0.2% to about 0.4%, or any suitable combination, subcombination, range or subrange thereof by weight, based on the weight of the cleaning composition. A person of ordinary skill in the art, however, will appreciate that other ranges are within the scope of the invention.

[0068] In some representative embodiments, the additional surfactant(s) include at least one non-ionic surfactant that includes caprylyl / capryl glucoside.

[0069] The amount of the additional surfactant(s) present in the cleaning composition is in a range of about 0.01% to about 5%, or about 0.02% to about 2%, or about 0.05% to about 1% by weight, or about 0.08% to about 1.5%, or about 0.1% to about 1.0%, or about 0.2% to about 0.7%, or any suitable combination, subcombination, range, or subrange thereof by weight, based on the weight of the cleaning composition. A person of ordinary skill in the art, however, will appreciate that other ranges are within the scope of the invention.

[0142] EXAMPLE 3: Evaluation of makeup removal with the inventive composition compared to comparative commercial reference compositions

[0143] We unexpectedly discovered that this type of multiphasic cosmetic liquid compositions can improve makeup removal performance with a broader spectrum for different types of makeup films.

[0144] The inventive and comparative compositions were tested in a study in which a foundation was applied to the skin and dried for 30 minutes. Each of the multiphasic liquid compositions which include Formula 1, Formula BF and Formula BPAN was shaken and 1 gram of the formed monophasic mixture was transferred onto a cotton pad. Each of the wet cotton pads was rubbed six times against the makeup film on the skin, and the makeup removal ability was estimated after rubbing. The results demonstrate that Formula 1 showed a per elimination performance comparable to that of the BPAN comparative formula, and better performance than the BF comparative formula.

[0145] The inventive and comparative compositions were also tested in a study in which the mascara was spread evenly on the skin and then dried for 1 hour. Each of the multiphasic liquid compositions that include Formula 1 and Formula BF was shaken and 1 gram of the formed single-phase mixture was transferred to a cotton pad. Each of the wet cotton pads was rubbed twice against the mascara film on the skin, and the removal capacity was estimated after rubbing. The results demonstrate that Formula 1 exhibited better removal performance than the comparative Formula BF.

[0148] Although the disclosure has been described with reference to a preferred embodiment, it will be understood by those skilled in the art that various modifications may be made and equivalents may be substituted for elements thereof without departing from the scope of the disclosure. Furthermore, numerous modifications may be made to adapt a particular situation or subject matter to the teachings of the disclosure without departing from its essential scope. Although various aspects and embodiments have been disclosed herein, other aspects and embodiments will be apparent to those skilled in the art. The various aspects and embodiments disclosed herein are for the purpose of illustration and are not intended to be limiting, the true scope and spirit being indicated by the following claims.

[0149] The adjective "any" means one, a few or all indiscriminately, whatever the quantity.

[0150] “At least one” as used herein means one or more and therefore includes the individual components as well as mixtures / combinations.

[0151] The transitional terms "comprising", "consisting essentially of" and "consisting of", when used in the appended claims, in their original and amended form, define the scope of the claim with respect to additional elements or steps not recited in the claim, if any, which are excluded from the scope of the claim(s). The term "comprising" is intended to be inclusive or open and does not exclude any additional element, process, step or material not recited. The term "consisting of" excludes any element, step or material other than those specified in the claim and, in the latter case, impurities ordinarily associated with the specified material(s). The phrase "consisting essentially of" limits the scope of a claim to the specified elements, steps, or materials and to those that do not materially affect the fundamental and novel feature(s) of the claimed disclosure. All materials and processes described herein that incorporate the present disclosure may, in other embodiments, be more specifically defined by any of the transitional terms "comprising," "consisting essentially of," and "consisting of."

[0152] The terms "free" and "devoid of" and "excludes" indicate that no reliably measurable excluded material is present in the cleaning composition, typically 0% by weight, based on the total weight of the cleaning composition. The term "substantially free" means that, although it is preferable that no excluded material be present in the cleaning composition, it is possible to have very small amounts of the excluded material in the cleaning composition of the invention, provided that such amounts do not materially affect the beneficial properties of the cleaning composition. In particular, "substantially free" means that the excluded material may be present in the cleaning composition in an amount of less than about 0.1% by weight, based on the total weight of the cleaning composition.

[0153] All percentages and ratios are calculated by weight unless otherwise indicated. All percentages are calculated based on the total composition unless otherwise indicated. In general, unless expressly stated herein, "weight" or "amount" as used herein with respect to the percentage of an ingredient refers to the amount of raw material comprising the ingredient, where the raw material may be described herein as comprising less than and up to 100% of the ingredient's activity. Accordingly, the weight percentage 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, where the final percentage of the active depends on the weight percentage of the active in the raw material.

[0154] All ranges and amounts given herein are intended to include sub-ranges and amounts using any disclosed point as the endpoint. 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 expressly stated. Similarly, a given range of "about 1% to 10%" is intended to have the term "about" modifying both the 1% and 10% bounds. Furthermore, it is understood that when an amount of a component is given, it is intended to mean the amount of active ingredient, unless otherwise stated. specific.

[0155] Notwithstanding that the numerical ranges and parameters that define the general scope of the disclosure are approximations, unless otherwise indicated, the numerical values ​​presented in the specific examples are reported as accurately as possible. However, any numerical value inherently contains certain errors necessarily resulting from the standard deviation found in their respective test measurements. The examples serve to illustrate embodiments of the present disclosure without, however, being limiting in nature.
