Description

[Technical Field]

[0001] The present invention relates to improved emollient compositions and cleansing compositions comprising the same for use in cleansing skin surfaces. Specifically, the present invention is useful for cleansing the facial area of ​​skin, and is particularly useful for cleansing (i.e., removing) various makeup products. [Background technology]

[0002] Due to the various skin, hair, and nail problems faced by consumers, consumers have long been seeking personal care products that can cleanse the skin or deliver and / or deposit beneficial agents that alleviate such problems.Facial cleansers should desirably provide a cleansing efficiency suitable for removing makeup products such as foundation, mascara, and eyeliner.However, it is important to avoid sacrificing the product's ability to properly cleanse the skin in order to reduce irritation to the user.Many delivery systems sacrifice aesthetics and cleaning ability to achieve stability and mildness.This is especially true when such products are used on sensitive areas such as the face, and more particularly when used on very sensitive areas such as around the eyes.It is beneficial that cleansing products can be applied by products such as wipes, sponges, or applicators, or can be applied directly by hand. Summary of the Invention [Problem to be solved by the invention]

[0003] Therefore, it would be desirable to create a composition that can adequately cleanse a user's skin. [Means for solving the problem]

[0004] According to the present invention, there is provided an emollient composition comprising: A. fatty acid glycol esters, B. Myristate alkyl ester; C. coconut fatty acid alkyl esters.

[0005] According to the present invention there is provided a cleansing composition comprising an emollient composition as defined herein and a surfactant.

[0006] The present invention also provides the use of the cleansing composition as defined herein or the emollient composition as defined herein to remove at least one of mascara, lipstick, and foundation from the surface of the skin. Specifically, the cleansing composition or emollient composition may be used to remove lipstick. DETAILED DESCRIPTION OF THE INVENTION

[0007] The present invention provides emollient compositions and cleansing compositions that offer optimal properties. As used herein, the term "optimal" includes comparable or improved cleansing efficacy compared to known cleansers. Optimal does not necessarily mean 100% cleansing efficiency, but rather an efficiency suitable for removing a sufficient amount of one or more cosmetics (i.e., makeup products) from the face. Efficient cleansing for various cosmetics is described in more detail below. Other advantages provided by the emollient compositions and cleansing compositions of the present invention may include one or more of the following: aesthetics, reduced stickiness, less irritation to the skin and eyes, achieving shorter drying times with less force and lower cost, reducing the amount of cleansing agent in the compositions, and the ability to make the emollient compositions and cleansing compositions silicone-free. Thus, the emollient compositions and / or cleansing compositions may be silicone-free. Additionally or alternatively, the emollient compositions and / or cleansing compositions of the present invention may be free of polyisobutenyl succinic anhydride-derived emulsifiers or polyisobutylene-derived emulsifiers. Additionally or alternatively, the emollient compositions and / or cleansing compositions may be preservative-free; specifically, cleansing compositions having a low water content, e.g., about 1% to about 10% by weight of water, may be preservative-free. As used herein, "free" of a component means that the emollient composition and / or cleansing composition contains no more than about 0.5% by weight of that component, preferably no more than about 0.1% by weight, and preferably no more than about 0.05% by weight. More preferably, the emollient composition and / or cleansing composition does not contain any of that component.

[0008] The emollient composition and / or the cleansing composition may contain only ingredients derived from naturally occurring compounds. Additionally, the emollient composition and / or the cleansing composition may contain only ingredients derived from plants. Thus, the emollient composition and / or the cleansing composition may be free of ingredients that are not derived from plants.

[0009] As used herein, unless otherwise specified, the term "percent" refers to percent by weight, and similarly, all amounts set forth herein are by weight. Also as used herein, the term "water-dispersible ingredient" refers to a material that, when combined with at least an equivalent weight amount of water, produces a uniform, clear or cloudy mixture. As used herein, the term "benefit agent" includes any active ingredient to be delivered to a desired location in and / or on the skin, hair, or nails, including, but not limited to, a cosmetic agent or pharmaceutical agent. "Cosmetic agent" means any ingredient suitable for cosmetically treating, nourishing, and / or conditioning hair, nails, and / or skin via topical application. "Pharmaceutical agent" means any drug suitable for topical use. As used herein, "medicine" includes agents that can promote recovery from trauma and illness.

[0010] The cleansing composition may further comprise one or more of water, thickeners, moisturizers, additional emollients, preservatives, fragrances, excipients, extracts, and buffers.Various combinations of the above ingredients may be useful in the present invention.The cleansing composition may be in the form of a liquid, cream, balm, or gel that is to be applied by hand or by a separate applicator, or may be provided in combination with a wipe, sheet, or sponge that is to be applied by an applicator device.

[0011] As used herein, "emollient" refers to a material used to cleanse the skin, hair, and eyelashes, to prevent or relieve dryness, or to protect the skin. Examples of emollients include, but are not limited to, hydrophobic compounds such as vegetable oils, mineral oils (e.g., petrolatum), and fatty acid esters (e.g., isopropyl palmitate, C12-C15 alkyl benzoates), including fatty acid esters of glycerol.

[0012] The cleansing composition may comprise the emollient composition in an amount of about 0.01% to about 60% by weight of the cleansing composition, about 1% to about 50% by weight of the cleansing composition, or about 2% to about 45% by weight of the cleansing composition, or about 5% to about 40% by weight of the cleansing composition, or about 10% to about 30% by weight of the cleansing composition, or about 15% to about 25% by weight of the cleansing composition, or about 1.5% to about 24% by weight of the cleansing composition, or about 2.5% to about 20% by weight of the cleansing composition, or about 5% to about 12% by weight of the cleansing composition, or about 7% to about 10% by weight of the cleansing composition. The emollient composition may be present in the cleansing composition in an amount of about 20% to about 40% by weight of the cleansing composition, or about 25% to about 35% by weight of the cleansing composition. The emollient composition may be present in the cleansing composition in an amount of about 30% by weight of the cleansing composition.

[0013] The cleansing composition can be formed by combining one or more components simultaneously or in any desired order.The emollient composition does not need to be formed separately from any other components, and the order of addition of the components of the cleansing composition can be changed as desired.In other words, when forming the cleansing composition, additional components can be added in any desired order together with any other components, including each emollient of the emollient composition.

[0014] The emollient composition includes three separate and distinct emollients. The emollient composition may include an additional emollient, for example, an additional alkyl ester may be present. Alternatively, or in addition, the emollient composition may include at least one additional ester, which may be a fatty acid ester.

[0015] Thus, the emollient composition comprises at least three emollients, where the first emollient, the second emollient, and the third emollient are each different from one another. The fatty acid glycol ester, the myristate alkyl ester, and the coconut fatty acid alkyl ester may be present in the same amount or substantially the same amount as one another. Alternatively, one of the fatty acid glycol ester, the myristate alkyl ester, and the coconut fatty acid alkyl ester may be present in a greater amount than the other two emollients. The emollient composition may consist of the fatty acid glycol ester, the myristate alkyl ester, the coconut fatty acid alkyl ester, and one or more additional emollients. The emollient composition may consist of the fatty acid glycol ester, the myristate alkyl ester, and the coconut fatty acid alkyl ester.

[0016] The fatty acid glycol ester may comprise a C8 to C22 fatty acid. The fatty acid glycol ester may comprise a C8 to C16 fatty acid. The fatty acid glycol ester may comprise a C10 to C14 fatty acid. Typically, the fatty acid glycol ester comprises a C12 fatty acid. The fatty acid glycol ester may be a fatty acid propylene glycol ester. The fatty acid glycol ester may be propylene glycol laurate. The fatty acid glycol ester may consist of propylene glycol laurate. Propylene glycol laurate may be commercially available under the trade name Schercemol PGML.

[0017] The alkyl group of the myristate alkyl ester may be a C3 to C22 alkyl. The alkyl group may be linear, branched, or cyclic. The alkyl group may have one, two, three, or four branch points. The branch point may have three bonds to other carbons and one bond to hydrogen, or four bonds to other carbons. The side chain attached to the branch point may be methyl, ethyl, propyl, or butyl. The branch point may be at the end of the alkyl group opposite the ester group, or adjacent to the ester group. Non-limiting examples include ethyl-hexyl, isopropyl, isopentyl, neopentyl, isohexyl, isodecyl, isododecyl, etc. Examples of linear alkyl groups include propyl, hexyl, nonyl, decyl, and hexadecyl. The alkyl group of the myristate alkyl ester may be a C3 to C12 alkyl, typically a C3 alkyl. The myristate alkyl ester may be isopropyl myristate. The alkyl myristate ester may comprise isopropyl myristate, which may be commercially available under the trade name Estol 1514.

[0018] The alkyl group of the coconut fatty acid alkyl ester may be a C3 to C22 alkyl. The alkyl group of the coconut fatty acid alkyl ester may be a C8 to C16 alkyl.

The coconut fatty acid alkyl ester may consist of decyl coconut, which may be commercially available under the trade name Tegosoft DC™.

[0019] In a preferred emollient composition, the fatty acid glycol ester is propylene glycol laurate, the myristate alkyl ester is isopropyl myristate, and the coconut fatty acid alkyl ester is decyl coconut.

[0020] The emollients of the present emollient compositions may be synthetic, e.g., derived from petroleum, or may be derived from renewable resources such as plant and animal materials such as triglyceride oils, or may be derived from a fermentation process, or may be derived from a mixture of sources.

[0021] It may be desirable to include, by weight of the emollient composition, a first emollient (fatty acid glycol ester), a second emollient (myristate alkyl ester), and a third emollient (coconut fatty acid alkyl ester). The first emollient, second emollient, and third emollient may each independently be present in an amount of about 10% to about 80% by weight of the emollient composition. It may be desirable for these three emollients to each be present in approximately equal amounts relative to one another (e.g., about 33.3% by weight of the emollient composition when no additional emollients are present). Alternatively, the first emollient and the second emollient may each independently be present in an amount greater than the third emollient, or the first emollient and the third emollient may each independently be present in an amount greater than the second emollient, or the second emollient and the third emollient may each independently be present in an amount greater than the first emollient. Alternatively, the first emollient, the second emollient, or the third emollient may be present in an amount greater than the other two emollients.

[0022] It may be desirable for the first emollient, the second emollient, and the third emollient to be present in a desired ratio relative to one another. For example, the first emollient, the second emollient, and the third emollient may be present in approximately equal amounts by weight (e.g., a weight ratio of about 1:1:1). That is, the fatty acid glycol ester, the myristate alkyl ester, and the coconut fatty acid alkyl ester may be present in a weight ratio of about 1:1:1.

[0023] However, it may be desirable to vary the amounts of the three emollients depending on the desired feel and cleansing desired.

[0024] The fatty acid glycol esters, myristate alkyl esters, and coconut fatty acid alkyl esters may be present in a weight ratio of about 1:1:8. The fatty acid glycol esters, myristate alkyl esters, and coconut fatty acid alkyl esters may be present in a weight ratio of about 1:8:1. The fatty acid glycol esters, myristate alkyl esters, and coconut fatty acid alkyl esters may be present in a weight ratio of about 8:1:1.

[0025] The glycol fatty acid ester, alkyl myristate ester, and alkyl coconut fatty acid ester may be present in a weight ratio of from about 1:1:1 to about 8:1:1, or from about 1.1:1:1 to about 8:1:1.

[0026] The fatty acid glycol ester, myristate alkyl ester, and coconut fatty acid alkyl ester may be present in a weight ratio of about 1:1:1 to about 1:8:1, or about 1:1.1:1 to about 1:8:1.

[0027] The fatty acid glycol ester, myristate alkyl ester, and coconut fatty acid alkyl ester may be present in a weight ratio of about 1:1:1 to about 1:1:8, or about 1:1:1.1 to about 1:1:8.

[0028] As noted above, the present cleansing compositions include an emollient composition and a surfactant.

[0029] The total amount of surfactants present may be from about 0.1% to about 50% by weight of the cleansing composition, or from about 20% to about 50% by weight of the cleansing composition, or from about 30% to about 50% by weight of the cleansing composition, or from about 35% to about 45% by weight of the cleansing composition. The total amount of surfactants present may be about 40% by weight of the cleansing composition. The total amount of surfactants present may be from about 0.1% to about 20% by weight of the cleansing composition, or from about 0.1% to about 10% by weight of the cleansing composition, or from about 0.1% to about 2% by weight of the cleansing composition, or from about 0.5% to about 0.75% by weight of the cleansing composition.

[0030] Surfactant is a surface active agent for cleansing or emulsifying.Suitable surfactant examples include those that can be found in Handbook of Cosmetic Science and Technology (edited by A. Barel, M. Paye and H. Maibach, published by Marcel Dekker, Inc., New York, NY, in 2001), Chapter 37, pages 431-450 (Classification of surfactants by L. Oldenhove de Guertechin), and include but are not limited to anionic surfactant, amphoteric surfactant, nonionic surfactant and cationic surfactant.

[0031] The surfactant included in the present cleansing composition may comprise a nonionic surfactant, or an anionic surfactant, or an amphoteric surfactant, or a cationic surfactant, or a combination of two or more thereof.

[0032] Preferably, the surfactant may include a nonionic surfactant. Preferably, the surfactant consists of one or more nonionic surfactants. The nonionic surfactant may include an essentially non-foaming nonionic surfactant. Exemplary suitable essentially non-foaming ionic surfactants include, for example, a blend of sucrose fatty acid esters. The blend of sucrose fatty acid esters may include sucrose combined with a fatty acid such as stearic acid, lauric acid, myristic acid, oleic acid, palmitic acid, and one or more combinations thereof. One such desirable blend of sucrose fatty acid esters is palm sucrose, available from Evonik Industries under the trade name Tegosoft® LSE.

[0033] "Essentially non-foaming" means that the surfactant has a column height of less than about 20 mm as measured by the Ross-Miles Foaming Test. See 18(I.) Oil & Soap 99-102(1941) ("Ross-Miles Test"), incorporated herein by reference. The cleansing compositions and personal care systems containing the cleansing compositions may be either rinsable with water or wiped off. It is desirable that any non-foaming nonionic surfactant used in the cleansing compositions described herein be rinsable with water or require no rinsing at all. The non-foaming nonionic surfactant may include a blend of sorbitan stearate and sucrose cocoate, available from Croda under the trade name "Arlacel 2121."

[0034] The surfactant may comprise or consist of PEG-7 glyceryl cocoate and hexylene glycol.

[0035] When included, the nonionic surfactant may be present in any desired amount, such as from about 0.1% to about 50% by weight of the cleansing composition, or from about 20% to about 50% by weight of the cleansing composition, or from about 30% to about 50% by weight of the cleansing composition, or from about 35% to about 45% by weight of the cleansing composition. The nonionic surfactant may be present in an amount of from about 0.1% to about 20% by weight of the cleansing composition, or from about 0.1% to about 10% by weight of the cleansing composition, or from about 0.1% to about 2% by weight of the cleansing composition, or from about 0.5% to about 0.75% by weight of the cleansing composition.

[0036] Alternatively or in addition, this cleansing composition may comprise anionic surfactant.As used herein, the term " anionic surfactant " refers to the surfactant that has negatively charged hydrophilic polar group.Examples of anionic surfactant include potassium cetyl phosphate, ammonium lauryl sulfate, sodium laureth sulfate, sodium lauryl sarcosinate, sodium myreth sulfate, sodium pareth sulfate, sodium stearate, sodium lauryl sulfate, α-olefin sulfonate, ammonium laureth sulfate, citrate (glyceryl stearate citrate), and their anionic fatty acids.

[0037] Alternatively, or in addition, the cleansing composition may contain an amphoteric surfactant. As used herein, the term "amphoteric" refers to 1) a molecule containing both acidic and basic sites, such as an amino acid containing both amino (basic) and acid (e.g., carboxylic acid, acidic) functional groups, or 2) a zwitterionic molecule that carries both positive and negative charges in the same molecule. The latter charge can be either dependent on or independent of the pH of the composition. Amphoteric surfactants are disclosed herein without counterions. Those skilled in the art will readily recognize that under the pH conditions of the compositions of the present invention, amphoteric surfactants are either electrically neutral because they have balanced positive and negative charges, or have counterions such as alkali metal, alkaline earth, or ammonium counterions. Examples of amphoteric surfactants suitable for use include, but are not limited to, amphocarboxylates such as alkylamphoacetates (mono or di), alkylbetaines, alkylamidoalkylbetaines (other than CAPB), alkylamidoalkylsultaines, alkylamphophosphates, phosphorylated imidazolines such as phosphobetaines and pyrophosphobetaines, carboxyalkylalkylpolyamines, alkylimino-dipropionates, alkylamphoglycinates (mono or di), alkylamphopropionates (mono or di), N-alkyl β-aminopropionic acids, alkylpolyaminocarboxylates, and mixtures thereof.

[0039] The cleansing composition may further comprise water. Alternatively, or in addition, the cleansing composition may comprise at least one additional ingredient. The additional ingredient may include, for example, cleansing ingredients such as carriers, thickeners, moisturizers, glycerides, preservatives, fragrances, etc.

[0040] The cleansing composition may include one or more humectants, including aliphatic diols. Other commercially available humectants capable of providing moisturizing and conditioning properties to the cleansing composition are suitable for use in the present invention. When present, the humectant is preferably present in an amount of from about 0.1 percent to about 4 percent, more preferably from about 0.5 percent to about 2 percent, and most preferably from about 0.5 percent to about 1 percent, based on the total weight of the cleansing composition. Examples of suitable humectants include, but are not limited to, 1) water-soluble liquid polyols selected from the group consisting of glycerin, propylene glycol, hexylene glycol, butylene glycol, pentylene glycol, dipropylene glycol, and mixtures thereof; 2) a compound of Formula I: HO-(R”O) b -H (I) wherein R" is an alkylene group having from about 2 to about 4 carbon atoms and b is an integer from about 1 to about 10; 3) a polyalkylene glycol such as PEG4, of formula II: CH3-C6H 10 O5-(OCH2CH2) c -OH (II) wherein c is an integer from about 5 to about 25; 4) urea; 5) fructose; 6) glucose; 7) honey; 8) lactic acid; 9) maltose; 10) sodium glucuronate; and 11) mixtures thereof.

[0041] In addition to the above-mentioned emollients, the cleansing composition may also contain a polymeric emulsifier. Useful polymeric emulsifiers include, for example, glycerides or triglycerides, including caprylic / capric triglyceride or PEG-6 caprylic / capric glyceride. Typically, the polymeric emulsifier may have a molecular weight of at least about 5000. Preferably, the polymeric emulsifier is a block copolymer having a hydrophilic portion and a hydrophobic portion. Other examples of suitable polymeric emulsifiers include, but are not limited to, polyethylene glycol-30 dipolyhydroxystearate available from Croda under the trade name "Cithrol DPHS"; dimethicone copolyol available from Goldschmidt Chemical Corporation under the trade name "Abil EM® 90"; substituted acrylates such as those available from Goodrich Corporation under the trade name "Pemulen®"; and mixtures thereof. When included, the polymeric emulsifier may be present in any desired amount, such as from about 0.1% to about 15% by weight of the cleansing composition, or from about 0.1% to about 2% by weight of the cleansing composition, or in an amount of about 0.75% by weight of the cleansing composition.

[0042] The cleansing composition may also include a preservative or preservative blend. Suitable preservatives include ingredients such as ethylhexylglycerin, dehydroacetic acid, benzoic acid, phenoxyethanol, polyaminopropyl biguanide, chlorphenesin, PEG-4 laurate, iodopropynyl butylcarbamate, and mixtures thereof. When included, the preservative may be present in any desired amount. For example, the preservative may be present in an amount of about 0.01% to about 2% by weight of the cleansing composition, or in an amount of about 0.1 to about 1% by weight of the cleansing composition. The preservative blend may include chlorphenesin and phenoxyethanol.

[0043] The cleansing composition may contain antioxidants such as vitamins (A, C, E), plant extracts (Coffea arabica, carotenoids, Prunus cerasus, Olea europaea, Camellia sinensis, Solanum lycopersicum, lycopene, Vitis vinifera, resveratrol, Thymus vulgaris, Rosmarinus officinalis), plant fermentation extracts (Lactobacillus / Saccharomyces / Curcuma ferment extract filtrate, Panax ginseng cambium cell culture, Saccharomyces / Ginseng flower ferment extract, Saccharomyces / Nelumbo nucifera ferment extract filtrate, Monascus / rice ferment broth, Saccharomyces / rice ferment filtrate extract, Damascena callus culture extract, Lactobacillus / white willow bark ferment filtrate, Lactobacillus / spirulina ferment filtrate), or a mixture of several plant extracts, such as Saccharomyces / (lavender / rosemary / sage / thyme) seed extract ferment filtrate.

[0044] Antioxidants can be particularly useful when the oil content in the cleansing composition is high to prevent chemical alteration of the oil, and may also have additional benefits for the skin.

[0045] The cleansing composition may also include a fragrance or fragrance blend. The fragrance may include essential oils or fragrant compounds, fixatives, extracts, vitamins, and solvents. If included, the fragrance may be present in any desired amount, such as from about 0.01% to about 1% by weight of the cleansing composition, or from about 0.1% to about 0.2% by weight of the cleansing composition.

[0046] The emollient composition and any additional ingredients may be formed together to make the cleansing composition, or may be formed as separate components in the cleansing composition. The designation "emollient composition" and "additional ingredients" is not intended to require separate formation of these two compositions. When processing the cleansing composition, it may be desirable to process the emollient composition and any additional ingredients separately, or the emollient composition and any additional ingredients may be processed as a single phase, with the order of addition of the additional ingredients being variable.

[0047] The cleansing composition may include a carrier. Specifically, the cleansing composition may include water. As described above, water does not necessarily need to be processed as a separate, distinct component. Water may be present in the cleansing composition in an amount of about 1% to about 95% by weight of the cleansing composition, or about 5% to about 50% by weight of the cleansing composition, or about 20% to about 40% by weight of the cleansing composition, preferably about 30% by weight of the cleansing composition. Water may be the most abundant component by weight in the cleansing composition. For example, water may be present in an amount of about 75% to about 95% by weight of the cleansing composition, or about 80% to about 85% by weight of the cleansing composition. Alternatively, the cleansing composition may have water in an amount of from about 1% to about 30% by weight of the cleansing composition, or from about 2% to about 20% by weight of the cleansing composition, or from about 2.5% to about 5% by weight of the cleansing composition.

[0048] The cleansing composition may further comprise one or more thickeners, which may be hydrophilic thickeners. Examples of suitable hydrophilic thickeners include, but are not limited to, carbomers, acrylate copolymers, and acrylate crosspolymers available from BFGoodrich under the trade name "Carbopol® EDT 2020" (INCI: Acrylates / C10-C30 Alkyl Acrylate Crosspolymer), Carbopol® Ultrez 10 NF Polymer (INCI: Carbomer), hydroxyethyl cellulose modified with cetyl ether groups available from Hercules under the trade name "Natrosol® Plus", polyvinylmethyl ether / maleic anhydride (PVM / MA) decadiene crosspolymer available from International Specialty Products under the trade name "Stabileze® QM", and copolymers and mixtures thereof, with carbomers being preferred. Examples of suitable acrylate copolymers include, but are not limited to, acrylate copolymer available from Rohm & Haas under the trade name "Aculyn® 33," acrylate / aminoacrylate copolymer available from National Starch & Chemical Company under the trade name "Structure Plus," acrylate / steareth-20 itaconic acid copolymer available from National Starch & Chemical Company under the trade name "Structure 2001," acrylate / ceteth-20 itaconic acid copolymer available from National Starch & Chemical Company under the trade name "Structure 3001," acrylate / steareth-20 methacrylate copolymer available from Rohm & Haas under the trade name "Aculyn® 22," and copolymers and mixtures thereof. Carbopol EDT 2020 is one of the components classified in the class of "carbomer interpolymer thickeners" and is useful in the present invention.When included, thickeners may be present in an amount of from about 0.05% to about 0.50% by weight of the cleansing composition, or from about 0.12% to about 0.18% by weight of the cleansing composition.

[0049] The cleansing composition may also include a buffering agent. Suitable buffering agents may include, for example, citrate buffer, phosphate buffer, lactate buffer, gluconate buffer, and sodium hydroxide. The buffering agent may be present in any amount desired to achieve the desired pH. The buffering agent may be a blend of 20% sodium hydroxide and water or other solvent. When included, the buffering agent may be present in an amount of about 0.01% to about 0.5% by weight of the cleansing composition, more preferably about 0.2% by weight of the cleansing composition.

[0050] The emollient composition may be formed separately from other additional ingredients, or may include the emollient composition formed with other additional ingredients except for a carrier, e.g., water, thereby forming a concentrated composition, which may be added separately to a carrier, e.g., water.

[0051] The cleansing composition may comprise, for example, about 30% of the emollient composition, about 40% surfactant, and about 30% water, by weight of the cleansing composition.

[0052] The cleansing and emollient compositions described herein are useful for removing various cosmetic (i.e., makeup) products from a user's skin, and in particular for efficiently removing mascara, foundation, lipstick, and eyeliner without leaving a heavy or sticky residue. Mascara has a reputation for being a difficult cosmetic material to remove from the skin because it deposits a high concentration of film-forming substances and contains a relatively high concentration of hydrophobic materials. Furthermore, mascara contains a high concentration of carbon-rich pigments, which imparts intense color. In addition, because mascara is typically applied to the eyes or eyelashes, cleansing requires gentle, low-pressure, non-planar application. Eyeliner presents its own removal challenges because it contains titanium dioxide, iron oxide, mica, silica, and higher concentrations of pigments / colorants, which can be more difficult to remove. In addition, like mascara, eyeliner is often applied to the eyes or eye area, and cleansing requires gentle, low-pressure, non-planar application. Foundations also pose some difficulties because they are typically emulsions and may contain silicones, which remain on the skin. Today's cosmetics are developed for "24-hour" use, meaning that the cosmetics remain on the user's skin for extended periods of time. These "long-lasting" waterproof cosmetics have high transfer resistance, making them difficult to remove.

[0053] It is particularly desirable to provide a material that effectively and thoroughly removes sufficient amounts of these three cosmetic materials (mascara, foundation, and lipstick). Furthermore, it is desirable to provide a composition that does not leave an oily or sticky residue on the skin's surface, as such oily cleansers can be difficult to remove and can leave the user feeling unclean. Additionally, it is useful for the cleansing composition to be mild or non-irritating to the skin, particularly the eyes. A soft and pleasant feel on the user's skin during and after use is also desirable. The present invention provides emollient compositions and cleansing compositions comprising the emollient compositions that have the desired properties defined herein while also providing suitable cleansing capabilities.

[0054] The cleansing composition may be used as a liquid or gel composition that is applied to the skin by the user's hands or other implements.Optionally, the cleansing composition may be impregnated or embedded into a substrate, such as a wipe or other application implement, in which case the user can simply remove the wipe or other application implement from the package and use the wipe or other application implement to achieve cleansing.The cleansing composition may be impregnated into an individual wipe, and the user can use the wipe to cleanse their skin.The individual wipes may be packaged in a dispenser that contains multiple wipes, or may be packaged in a dispenser that contains only one wipe.Desirable substrates include wipes, which are described in more detail below.

[0055] The cleansing composition may optionally further contain one or more benefit agents or pharmaceutically acceptable salts thereof. As used herein, the term "benefit agent" includes any active ingredient, such as a cosmetic or pharmaceutical agent, that is to be delivered into and / or onto the skin, hair, or nails at the desired location. "Cosmetic agent" means any ingredient that is suitable for cosmetically treating, nourishing, and / or conditioning hair, nails, and / or skin through topical application.

[0070] The cleansing composition can be prepared by combining desired components in a suitable container, and mixing them under any desired conditions using any conventional mixing means known in the art, such as mechanically stirring propellers, paddles, etc. Process can also include the steps of forming the emollient composition and adding one or more additional components to the emollient composition to produce the cleansing composition separately. Alternatively, the cleansing composition can be formed by combining these components in any desired order, and in this case, the order of adding components can be changed. Alternatively, the cleansing composition can be formed by combining these components in any order, except for water, and then adding water separately to the premix to form the cleansing composition.

[0071] The cleansing composition may be provided in a liquid, gel, balm, or cream form in a container so that the cleansing composition can be applied to the skin by the user manually or with a cloth, wipe, sheet, or other device, or alternatively, the cleansing composition may be embedded in or impregnated into a wipe or multiple sheets or wipes so that the cleansing composition can be applied to the skin by wiping with a sheet, wipe, or other device.

[0072] Since the cleansing composition is applied to the face and is preferably used to remove cosmetic materials, it may be desirable to impregnate the cleansing composition into a sheet or wipe and provide it to the user in this form.The user removes the impregnated wipe from a suitable airtight package and applies it directly to the skin.Therefore, a system or package may contain multiple wipes in a resealable package, each of which is impregnated with the cleansing composition of the present invention or contains the composition in other ways.In other embodiments, each individual wipe may be contained in its own airtight package or container, and the package may be discarded after the wipe contained therein is used.The wipe is preferably disposable and contains degradable components, thereby providing environmental health. Wipe materials can include, for example, natural, biodegradable, or synthetic fibers or filaments (some examples of which include wool, silk, jute, hemp, cotton, flax, sisal, or ramie), or synthetic (some examples of which include rayon, cellulose esters, polyvinyl derivatives, polyolefins such as polyethylene and polypropylene, polyamides such as nylon 6 and nylon 6,6, or polyesters such as polyethylene terephthalate and polybutylene terephthalate), or combinations thereof. These nonwoven materials are generally described in the INDA "NONWOVEN FABRICS HANDBOOK" (1999) for nonwoven substrates and methods of making them. One particular substrate that may be useful is an embossed spunlaced nonwoven material made from a mixture of 20% rayon 1.7 dtex, 40% polyester (PET) 1.3 dtex, and 40% polyester (PET) 1.7 dtex. The basis weight of the substrate can vary, but generally ranges from about 20 grams per square meter to about 500 grams per square meter, for example, from about 50 grams per square meter to about 150 grams per square meter.The wipe substrate may be of any desired size and may have any desired area, including a length of about 2 to 10 inches and a width of about 2 to 10 inches, and more desirably a length of about 7 to 8 inches and a width of about 7 to 8 inches. Other suitable wipe materials include those described in European Patent No. 1283019(B1), U.S. Patent No. 9,622,944, and U.S. Patent Application No. 2016 / 0367102, the entire disclosures of each of which are incorporated herein by reference in their entirety.

[0073] The composition may be provided to the user in a liquid, balm, or gel dispensing bottle or container, where the user applies the composition by hand or applies the composition to a wipe or other applicator device, and then uses the applicator to cleanse the skin. The composition may be sold in a single dispensing bottle or in a kit, where the package includes a dispensing bottle with the composition therein and multiple applicator devices, such as wipes or bowls.

[0074] The present invention includes not only the cleansing composition described above, but also a method of using the cleansing composition described above. The method includes applying an effective amount of the composition to skin (including facial skin and skin near the eyes) and cleansing the skin with the composition. The composition can be applied to the skin by hand or by using an applicator (e.g., a sheet, a wet wipe, a sponge, a brush, etc.). The composition can be applied to the skin when the skin is wet or dry, and after application, the composition can be wiped off the skin, washed off the skin, or allowed to dry. It is particularly desirable to apply the composition to the skin via a pre-impregnated wipe and allow the skin to dry without further washing or cleaning by the user. The used wipe can be disposed of by the user. The invention described herein may be practiced in the absence of any component, ingredient, or step not specifically disclosed herein, or may include additional components or steps not explicitly disclosed herein.

[0075] As described above, the present invention relates to a composition that can be used to effectively and efficiently cleanse various cosmetics from the user's skin surface. The composition of the present invention should be able to efficiently remove, for example, foundation, lipstick, eye shadow, lip liner, eyebrow pencil, pomade, brush mascara, and / or eyeliner. Furthermore, the composition of the present invention may be completely or substantially free of silicone.

[0076] The present invention will be better understood through the following examples, which are exemplary in nature and are not intended to be limited to any particular combination of elements. [Example]

[0077] The following examples illustrate the formulation of compositions that may be useful either by themselves or as part of a cleansing composition to cleanse various makeup materials from a user's skin. The method used to evaluate the cleansing efficacy of makeup removers is a combination of mechanical cleansing with a texture analyzer, a controlled light image capture system, and an image analysis system with Matlab.

[0078] The texture analyzer used in these examples is called a texturometer, which provides a reproducible mechanical movement to clean a model surface soiled with a makeup remover product. The texture analyzer simultaneously considers force, distance, and time. The speed can be fixed and then the force fluctuation can be measured, or the displacement can be controlled to maintain a constant force. To do so, the instrument has a force capturer.

[0079] The texturometer used in these examples is called TA.XT-plus, manufactured by Stable Micro Systems (UK). The TA.XT-plus was used for all measurements described herein. The software used was Texture Exponent 32, manufactured by Stable Micro Systems (Cardiff, UK).

[0080] For the friction measurements the following was used: a friction rig HFS (Horizontal Friction System, Stable Micro Systems) and a mobile with a weight of 204 g and dimensions of 15 x 8 cm, screwed to the texturometer.

[0081] A PMMA (PolyMethylMethAcrylate) sample plate (80 × 80 cm) was used to mimic the skin support. If desired, other materials such as Bioskin plates (Viewlux Co., Ltd., Saitama, Japan), ABS (acrylonitrile butadiene styrene), PVC, or HDPE could be used.

[0082] To hold the sample plate, a solid support was 3D printed (PLA, Polylactic acid). The solid support was fixed onto the tray of the friction rig and taped down to prevent movement while the moving body was moving back and forth on it.

[0083] A Canon camera with a Nikon D90 (Nikon Japan) + Nikon AF Micro Nikkor 105mm 1:2.8 D lens was used to analyze each sample described herein. It was positioned so that it could take pictures of the cleansing tests. It was held in place by a camera arm (145° angle). A photo studio (80 x 80 x 80 cm) containing two LEDs was used to optimize the quality of the photos. The texturometer and camera were placed inside.

[0084] For this study, the protocol for makeup plate preparation was as follows: Fix the film applicator (100mm BEVS 1806B / 100 BEVS INDUSTRIAL CO. LIMITED (Guangzhou, China)) on the laboratory bench with double-sided adhesive tape. Weigh the PMMA plate; A template paper with a circular hole (diameter 2.5 cm) in the center is attached onto the PMMA plate. Fill the holes with makeup, Adjust the height of the film applicator depending on the makeup (approximately 2.6 mm for mascara and lipstick, and approximately 2.45 mm for foundation, but this height may vary slightly depending on the thickness of the PMMA plate) (thickness = PMMA plate + tested makeup), ○ Pass the PMMA plate under the film applicator, Remove the template paper and weigh the plate, thereby determining the make-up mass on the plate; Allow the plate to dry at room temperature (approximately 20°C) for 12 hours to a maximum of 48 hours.

[0085] For the mobile body calibration, it was desirable to bring the mobile body as close as possible to the friction rig to calibrate the height of the probe. The "removable support" is the friction rig HFS (Horizontal Friction System, Stable Micro Systems) and a mobile body weighing 204 g and measuring 15 x 8 cm.

[0086] To measure the results, the following setup process was used: a cotton pad (Demak up®, cotton science™ expert honeycomb texture 100% biodegradable natural cotton fiber, manufactured by Essity, SA, Belgium) was fixed onto a removable support with double-sided adhesive tape. Then, 3 mL of emollient (or emollient composition) was placed onto the cotton pad, the removable support was turned over onto the fixed support, and a 2 kg mass was placed onto the removable support.

[0087] The makeup removal efficiency analysis was performed as follows: the removable support was configured to automatically displace 70 mm. The displacement was reproduced several times depending on the type of makeup investigated: five times for mascara and lipstick, and twice for foundation. Photographs of the PMMA plate were taken before every movement ("before image") and at the end of the displacement sequence of the removable support ("after image"). The photographs thus obtained (before / after) for each sample were analyzed in Matlab to evaluate the cleansing efficiency of the emollient.

[0088] For mascara, color was assessed in the before and after images, each assigned the average color value (referred to as Bval) of each pixel within the circle where the makeup was applied in the "before" and "after" images. The Bval of the "after" image was compared to the Bval of the "before" image, and the ratio was taken as the Bratio number (Bval of "after" image / Bval of "before" image). It was determined that Bratio was more appropriate for mascara because it effectively assesses gray levels.

[0089] For lipsticks and foundations, which contain more shades than mascara, it was determined that the clean plate test was a more appropriate evaluator of cleansing ability. For each test, the clean plate value was defined as ((number of elements in chroma matrix - number of non-zero elements in chroma matrix) / number of elements in chroma matrix) x 100.

[0090] The chrominance matrix in the Lab color space is

[0092] The makeup products tested included: Mascara: Neutrogena Hydro Boost Plumping Mascara Waterproof Lipstick: L'Oreal Color Riche No. 297 Red Passion Foundation: L'Oreal Accord Parfait 3D Beige Dress

[0093] Various emollients tested in the examples below included: Schercemol PGML; INCI name: Propylene glycol laurate; Supplier: Lubrizol Schercemol IDO; INCI name: Isodecyl oleate; Supplier: Lubrizol Estol 1514; INCI name: Isopropyl myristate; Supplier: Croda ○ Cegesoft PFO; INCI name: Passiflora Incarnata oil; supplier: BASF Crodamar 227; INCI name: Decyl isooctadecanoate; Supplier: Croda Decyl; INCI name: Decyl Cocoate; Supplier: Evonik Arlamol HD; INCI name: Isohexadecane; Supplier: Croda Organic cold-pressed virgin apricot kernel oil; INCI name: Prunus armeniaca kernel oil; Supplier: GreenTech

[0094] Individual emollients The first set of experiments investigated the cleansing properties of a select group of emollients. The emollients were tested alone, in the form received from the supplier (i.e., not in combination with other emollients or in a formulation).

[0095] As above, Bval and Bratio measurements were taken for mascara, and clean plate measurements were taken for lipstick and foundation.

[0096] 1. Mascara The Bval and Bratio values ​​of selected emollients on mascara stains are presented below in Table 1. For mascara, the Bratio value is considered a good indicator of the ability to remove mascara from a surface, with higher Bratio values ​​indicating better cleansing efficacy scores.

[0097] [Table 1]

[0098] As can be seen from Table 1, Estol 1514 was found to have the highest Bratio value for mascara smudge removal. Other suitable emollients identified in the above table include Arlamol HD, Tegosoft DC MB, and Schercemol IDO.

[0099] 2.Lipstick The clean plate values ​​of selected emollients on lipstick stains are presented below in Table 2. Higher clean plate values ​​are considered to be associated with better cleansing profiles.

[0100] [Table 2]

[0101] As can be seen from Table 2, Crodamar 227 was identified as the most promising emollient for removing lipstick stains. Other suitable emollients such as Schercemol IDO, Prunus armeniaca, Estol 1514, and Arlamol HD show comparable results.

[0102] 3. Foundation The clean plate values ​​of selected emollients on foundation stains are presented below in Table 3. Higher clean plate values ​​are considered to be associated with better cleansing profiles.

[0103] [Table 3]

[0104] As can be seen from Table 3, Estol 1514, Arlamol HD, Schercemol PGML, Tegosoft DC MB, and Schercemol IDO all exhibited promising foundation stain cleansing properties.

[0105] Emollient Combination In a second set of experiments, the cleansing properties of emollient compositions containing combinations of emollients were investigated to see if a combination could be identified that showed promising results against all three types of makeup stains (mascara, lipstick, and foundation). The percentages of emollients are listed as weight percent of the emollient compositions tested.

[0106] Several combinations were tested and the data presented here highlight the most promising results, which involved a mixture of Tegosoft DC MB, Estol1514, and Schercemol PGML.

[0107] 1. Mascara The Bratio values ​​of emollient compositions containing three selected emollients at different ratios against mascara smear are presented in Table 4.

[0108] [Table 4]

[0109] A high Bratio value of 2.93 was obtained with the mixture of the three selected emollients. In comparison, referring to the table above, the Bratio values ​​of the three emollients obtained separately were 2.46 (Estol1514), 2.32 (Tegosoft DC MB), and 1.75 (Schercemol PGML). Therefore, it was determined that the cleansing efficacy against mascara stains was slightly improved compared to the individual emollients. In particular, when these three emollients were used in approximately equal amounts, or when a larger amount of Schercemol PGML was used, the cleansing efficacy was improved.

[0110] 2.Lipstick The clean plate values ​​of mixtures containing different proportions of the three selected emollients against lipstick stains are presented in Table 5.

[0111] [Table 5]

[0112] A high clean plate value of 91.88 was obtained with the mixture of the three selected emollients. In comparison, referring to the table above, the clean plate values ​​obtained for the three emollients individually were 49.74 (Estol 1514), 43.77 (Tegosoft DC MB), and 36.82 (Schercemol PGML). The cleansing efficacy against lipstick stains was found to be significantly improved compared to the individual emollients. The cleansing efficacy of the mixture at each ratio was higher than the individual efficacy of each of these emollients. Furthermore, when the amount of Estol 1514 was higher or the amount of Tegosoft DC MB was higher, the combination was found to be superior to the most effective emollient identified in the first set of experiments: Crodamar 227 (69.27). At the highest or even at approximately equal amounts of Schercemol PGML, cleansing efficacy was similar to that of the individual Crodamar 227.

[0113] Surprisingly, the cleansing efficacy of a moderately effective emollient (Estol 1514) was enhanced by the other two emollients, which exhibited the lowest efficacy.

[0114] 3. Foundation The clean plate values ​​of mixtures containing different proportions of the three selected emollients against foundation stains are presented in Table 7.

[0115] [Table 6]

[0116] When the three were used in approximately equal amounts, clean plate values ​​of up to 94.8 were obtained for mixtures of the three selected emollients. As noted above, the clean plate values ​​of the three emollients obtained separately were similar, ranging from 99.3 (Estol 1514) to 94.5 (Tegosoft DC MB). The cleansing efficacy of the individual emollients was significantly higher for foundation, and therefore the cleansing efficacy of the blended combination for removing foundation stains was comparable to that of the emollients obtained separately.

[0117] conclusion Based on the above-mentioned individual cleansing test and the cleansing test of the three emollients blended together, it can be seen that the combination of Tegosoft DC MB, Estol1514 and Schercemol PGML shows excellent cleansing results for removing makeup stains, including mascara, lipstick and foundation.The results of the blended combination of emollients for removing lipstick and mascara are improved compared with the results of the emollients obtained separately.The cleansing results of the blended combination for removing foundation are consistent with the observation results made on the emollients obtained separately.

[0118] In particular, the cleansing results of the blended combination of emollients for removing lipstick were surprisingly high compared to the results of the emollients obtained separately, and therefore, it was determined that the combination of these three emollients was more effective in removing overall makeup ingredients.
