Description

Technical Field

[0001] The present invention relates to improved emollient compositions for cleansing the skin surface and cleansing compositions comprising the same. In particular, the present invention is useful for cleansing the facial area of ​​the skin and is especially useful for cleansing (ie, removing) various cosmetic products. Background Art

[0003] Because consumers face various skin, hair and finger / toe problems, consumers have long been seeking personal care products that can clean skin or deliver and / or deposit beneficial agents that can alleviate such problems. Facial cleansers should desirably provide suitable cleaning efficiency to remove makeup products, such as foundation, mascara and eyeliner. However, it is important to avoid sacrificing the ability of the product to fully clean the skin in order to reduce the stimulation to the user. In order to obtain stability and reduced irritation, many delivery systems sacrifice aesthetics and cleaning ability. When such products are used in sensitive areas (such as the face), and even more particularly, in very sensitive areas around the eyes, this is especially true. Beneficially, the cleaning product can be applied by products such as wipes, sponges or applicators, or directly applied by hand.

[0004] It would therefore be desirable to create such compositions that are able to adequately cleanse the user's skin. Summary of the invention

[0005] According to the present invention, there is provided a skin moisturizer composition, comprising:

[0006] A. Ethylene glycol esters of fatty acids;

[0007] B. alkyl esters of myristic acid; and

[0008] C. Alkyl esters of coconut acid.

[0009] According to the present invention there is provided a cleaning composition comprising an emollient composition as defined herein and a surfactant.

[0010] According to the present invention, there is also provided a use of a cleaning composition as defined herein or an emollient composition as defined herein to remove at least one of mascara, lipstick and foundation from the skin surface. Specifically, the cleaning composition or the emollient composition can be used to remove lipstick. DETAILED DESCRIPTION

[0011] The present invention provides emollient compositions and cleaning compositions that deliver optimal properties. As used herein, the term "optimal" includes cleaning efficacies comparable or improved compared to known cleansers. Optimal does not necessarily mean 100% cleaning efficiency, but the appropriate efficiency of removing a sufficient amount of one or more cosmetics (i.e., cosmetic products) from the face. The effective cleaning for various cosmetics is described in more detail below. Other beneficial effects provided by the emollient composition and / or cleaning compositions of the present invention may include one or more of the following: aesthetics, reduced greasyness, low irritation to the skin and eyes, achieving shorter drying time with less force and lower cost, reducing the amount of cleansers in the composition, and making the emollient composition and cleaning compositions free of silicone. Therefore, the emollient composition and / or cleaning compositions may not contain silicone. Additionally or alternatively, the emollient composition and / or cleaning compositions of the present invention may not contain emulsifiers derived from polyisobutylene succinic anhydride or emulsifiers derived from polyisobutylene. Additionally or alternatively, the emollient composition and / or the cleaning composition may be preservative-free, specifically, a cleaning composition with a low water content (such as having about 1 wt % to about 10 wt % water) may be preservative-free. As used herein, the so-called "free" component means that the emollient composition and / or the cleaning composition has about 0.5 wt % or less, preferably about 0.1 wt % or less, preferably about 0.05 wt % or less of the component. More preferably, the emollient composition and / or the cleaning composition does not contain any of the components.

[0012] The emollient composition and / or the cleaning composition may contain only components derived from naturally occurring compounds. In addition, the emollient composition and / or the cleaning composition may contain only components of plant origin. Therefore, the emollient composition and / or the cleaning composition may not contain components of non-plant origin.

[0013] As used herein, the term "percentage" shall refer to weight percentage, and similarly, unless otherwise specified, all amounts shown herein shall be by weight. Also as used herein, the term "water-dispersible component" shall mean a material that produces a uniform, transparent or turbid mixture when combined with at least a weight equivalent of water. The term "beneficial agent" used herein includes any active ingredient that will be delivered to the desired position in and / or on the skin, hair or finger / toenails, including but not limited to agents such as cosmetic agents or pharmaceutical agents. So-called "cosmetic agents" means any ingredient suitable for cosmetic treatment, providing nutrients and / or conditioning hair, finger / toenails and / or skin via topical application. So-called "pharmaceutical agents" means any medicine suitable for topical use. As used herein, "medicament" includes those agents that can promote recovery from damage and disease.

[0014] The cleaning composition may also include one or more of the following: water, thickeners, humectants, additional emollients, preservatives, fragrances, excipients, extracts and buffers. Various combinations of the above components can be used in the present invention. The cleaning composition can be in the form of a liquid, cream, balm or gel, applied by hand or a separate applicator, or can be provided in combination with a wipe, sheet or sponge so as to be applied by an applicator device.

[0015] As used herein, "emollient" refers to a material used to clean the skin, hair and eyelashes, prevent or alleviate dryness, or protect the skin. Examples of emollients include, but are not limited to, hydrophobic compounds such as vegetable oils, mineral oils (e.g., petrolatum), fatty esters (e.g., isopropyl palmitate, C12-C15 alkyl benzoate), including those fatty esters of glycerol, etc.

[0016] The cleaning composition may include an emollient composition in the following amounts: from about 0.01% to about 60% by weight of the cleaning composition. The cleaning composition may include an emollient composition in the following amounts: from about 1% to about 50% by weight of the cleaning composition, or from about 2% to about 45% by weight, or from about 5% to about 40% by weight, or from about 10% to about 30% by weight, or from about 15% to about 25% by weight, or from about 1.5% to about 24% by weight of the cleaning composition, or from about 2.5% to about 20% by weight of the cleaning composition, or from about 5% to about 12% by weight of the cleaning composition, or from about 7% to about 10% by weight of the cleaning composition.

The emollient composition may be present in the cleaning composition in the following amounts: about 30% by weight of the cleaning composition.

[0017] The cleaning composition can be formed by combining one or more elements simultaneously or in any desired order. The emollient composition need not be formed from any other components alone, and the order of addition of the components of the cleaning composition can vary as desired. In other words, when forming the cleaning composition, the additional components can be added with any other components, including adding each emollient of the emollient composition in any desired order.

[0018] The emollient composition comprises three separate and distinct emollients. The emollient composition may comprise an additional emollient, for example, an additional alkyl ester may be present. Alternatively or in addition, the emollient composition may comprise at least one additional ester, which may be an ester of a fatty acid.

[0019] Therefore, the emollient composition comprises at least three kinds of emollients, wherein the first emollient, the second emollient and the third emollient are different from each other. The glycol esters of fatty acids, the alkyl esters of myristic acid and the alkyl esters of coconut oil can be present in the same amount or substantially the same amount as each other. Alternatively, one of the glycol esters of fatty acids, the alkyl esters of myristic acid and the alkyl esters of coconut oil can be present in an amount greater than the other two emollients. The emollient composition can be composed of the glycol esters of fatty acids, the alkyl esters of myristic acid, the alkyl esters of coconut oil and one or more additional emollients. The emollient composition can be composed of the glycol esters of fatty acids, the alkyl esters of myristic acid and the alkyl esters of coconut oil.

The ethylene glycol ester of fatty acids may comprise C10 to C14 fatty acids. Typically, the ethylene glycol ester of fatty acids comprises C12 fatty acids. The ethylene glycol ester of fatty acids may be a propylene glycol ester of fatty acids. The ethylene glycol ester of fatty acids may be propylene glycol laurate. The ethylene glycol ester of fatty acids may consist of propylene glycol laurate. Propylene glycol laurate is commercially available under the trade name Schercemol PGML.

[0021] The alkyl group of the alkyl ester of myristic acid can be a C3 to C22 alkyl group. The alkyl group can be linear, branched or cyclic. The alkyl group can have one, two, three or four branch points. The branch point can have three bonds bonded to other carbons and one bond bonded to hydrogen, or four bonds bonded to other carbons. The side chain attached to the branch point can be a methyl, ethyl, propyl or butyl group. The branch point can be located at the end of the alkyl group, opposite to or close to the ester group. Non-limiting examples include ethyl-hexyl, isopropyl, isopentyl, neopentyl, isohexyl, isodecyl, isododecyl, etc. Examples of straight-chain alkyl groups include propyl, hexyl, nonyl, decyl and hexadecyl. The alkyl group of the alkyl ester of myristic acid can be a C3 to C12 alkyl, typically a C3 alkyl. The alkyl ester of myristic acid can be isopropyl myristate. The alkyl ester of myristic acid can be composed of isopropyl myristate. Isopropyl myristate is commercially available under the trade name Estol 1514.

[0022] The alkyl group of the alkyl ester of coconut oil can be a C3 to C22 alkyl group. The alkyl group of the alkyl ester of coconut oil can be a C8 to C16 alkyl group.

The alkyl ester of coconut oil can be composed of decyl cocoate. Decyl cocoate can be the decyl cocoate that can be obtained under the trade name Tegosoft DC TM Commercially available.

[0023] In a preferred emollient composition, the glycol ester of a fatty acid is propylene glycol laurate, the alkyl ester of myristic acid is isopropyl myristate, and the alkyl ester of coconut acid is decyl cocoate.

[0024] Emollients The emollients of the composition may be synthetic, for example derived from petroleum, or may be derived from renewable resources such as plant and animal materials (eg, triglyceride oils), or from fermentation processes, or may be derived from a mixture of resources.

[0025] It may be desirable to include a first emollient (ethylene glycol ester of fatty acid), a second emollient (alkyl ester of myristic acid), and a third emollient (alkyl ester of coconut oil) by weight relative to the emollient composition. The first emollient, the second emollient, and the 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 to each of the three emollients to be present at about the same weight relative to each other (e.g., in the absence of an additional emollient, each emollient is about 33.3% by weight of the emollient composition). 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.

[0026] It may be desirable for the first, second, and third emollients to be present in a desired ratio relative to one another. For example, the first, second, and third emollients may be present in approximately equal amounts by weight (e.g., a weight ratio of about 1:1:1). That is, the glycol esters of fatty acids, the alkyl esters of myristic acid, and the alkyl esters of coconut acid may be present in a weight ratio of about 1:1:1.

[0027] However, depending on the desired feel and desired cleansing, it may be preferred to modify the amounts of the three emollients.

[0028] The ethylene glycol esters of fatty acids, the alkyl esters of myristic acid, and the alkyl esters of coconut acid may be present in a weight ratio of about 1:1:8. The ethylene glycol esters of fatty acids, the alkyl esters of myristic acid, and the alkyl esters of coconut acid may be present in a weight ratio of about 1:8:1. The ethylene glycol esters of fatty acids, the alkyl esters of myristic acid, and the alkyl esters of coconut acid may be present in a weight ratio of about 8:1:1.

[0029] The ethylene glycol esters of fatty acids, the alkyl esters of myristic acid, and the alkyl esters of coconut acid may be present in a weight ratio of about 1:1:1 to about 8:1:1, or about 1.1:1:1 to about 8:1:1.

[0030] The ethylene glycol esters of fatty acids, the alkyl esters of myristic acid, and the alkyl esters of coconut acid 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.

[0031] The ethylene glycol esters of fatty acids, the alkyl esters of myristic acid, and the alkyl esters of coconut acid 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.

[0032] As noted above, the cleansing composition comprises an emollient composition and a surfactant.

[0033] The total amount of surfactant present may be from about 0.1% to about 50% by weight of the cleaning composition, or from about 20% to about 50% by weight of the cleaning composition, or from about 30% to about 50% by weight of the cleaning composition, or from about 35% to about 45% by weight of the cleaning composition. The total amount of surfactant present may be about 40% by weight of the cleaning composition. The total amount of surfactant present may be from about 0.1% to about 20% by weight of the cleaning composition, or from about 0.1% to about 10% by weight of the cleaning composition, or from about 0.1% to about 2% by weight of the cleaning composition, or from about 0.5% to about 0.75% by weight of the cleaning composition.

[0034] Surfactant is a surface active agent intended to clean or emulsify. Examples of suitable surfactants include those found in Chapter 37, pp. 431-450 (Classification of surfactants by L. Oldenhove de Guertechin) of Handbook of Cosmetic Science and Technology (edited by A. Barel, M. Paye and H. Maibach, published in 2001 by Marcel Dekker, Inc.

[0035] The surfactant included in the cleaning composition may include a nonionic surfactant, or an anionic surfactant, or an amphoteric surfactant, or a cationic surfactant, or a combination of two or more thereof.

[0036] Preferably, the surfactant may comprise a nonionic surfactant. Preferably, the surfactant consists of one or more nonionic surfactants. The nonionic surfactant may comprise a substantially non-foaming nonionic surfactant. Exemplary suitable substantially non-foaming ionic surfactants include, for example, a blend of sucrose fatty acid esters. The blend of sucrose fatty acid esters may comprise sucrose in combination with a fatty acid such as stearic acid, lauric acid, myristic acid, oleic acid, palmitic acid, and combinations of one or more thereof. One such desirable blend of sucrose fatty acid esters is sucrose cocoate, which can be found under the trade name LSE is commercially available from Evonik Industries.

[0037] By "substantially non-foaming" is meant that the surfactant has a column height of less than about 20 mm as determined by the Ross-Miles Foam Generation Test. See 18 (I.) Oil & Soap 99-102 (1941) ("Ross-Miles Test"), which is incorporated herein by reference. Cleaning compositions and personal care systems comprising the cleaning compositions can be rinsed or wiped with water. It is desirable that any non-foaming non-ionic surfactant used in the cleaning compositions described herein can be rinsed with water or does not require rinsing at all. The non-foaming non-ionic surfactant may include a blend of sorbitan stearate and sucrose cocoate, available from Croda under the trade name "Arlacel 2121".

[0038] The surfactant may comprise or consist of PEG-7 glyceryl cocoate and hexylene glycol.

[0050] In addition to the above-mentioned emollients, the cleaning composition may also include a polymeric emulsifier. Useful polymeric emulsifiers include glycerides or triglycerides, including, for example, caprylic / capric triglycerides or PEG-6 caprylic / capric glycerides. 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, which is available under the trade name "Abil 90" is available from Goldschmidt Chemical Corporation; substituted acrylates, such as those sold under the trade names those available from The Goodrich Corporation; and mixtures thereof.

[0053] Antioxidants can be particularly useful where the cleansing composition is high in oil to prevent chemical changes to the oil and can also have additional benefits to the skin.

[0054] The cleaning composition may also include a fragrance or a fragrance blend. Fragrances may include essential oils or fragrance compounds, fixatives, extracts and vitamins, and solvents. When a fragrance is included, the fragrance may be present in any desired amount, for example, from about 0.01% to about 1% by weight of the cleaning composition, or from about 0.1% to about 0.2% by weight of the cleaning composition.

[0055] The emollient composition and any additional components can be formed together to prepare the cleaning composition, or they can be formed as separate components in the cleaning composition. The designations "emollient composition" and "additional components" are not intended to require the separate formation of the two compositions. When processing the cleaning composition, it may be desirable to process the emollient composition and any additional components separately, or the emollient composition and any additional components can be processed as a single phase, wherein the order of addition of the components is variable.

[0056] The cleaning composition may include a carrier. Specifically, the cleaning composition may include water. As described above, water need not be treated as a separate and unique component. Oil may be present in the cleaning composition in the following amounts: from about 1% to about 95% by weight of the cleaning composition, or from about 5% to about 50% by weight of the cleaning composition, or from about 20% to about 40% by weight of the cleaning composition, or from about 30% by weight of the cleaning composition. Water may be the largest component by weight in the cleaning composition.

[0057] The cleaning composition may further comprise one or more thickeners, which may be hydrophilic thickeners. Examples of suitable hydrophilic thickeners include, but are not limited to, those sold under the trade name " EDT 2020”(INCI: Acrylates / C10-C30 Alkyl Acrylate Crosspolymer), Ultrez 10 NF polymer (INCI: Carbomer) is available from BF Goodrich as Carbomer, Acrylates Copolymer and Acrylates Crosspolymer under the trade name " Hydroxyethylcellulose modified with hexadecene groups is available from Hercules under the trade name " Polyvinyl methyl ether / maleic anhydride (PVM / MA) decadiene crosspolymers available from International Specialty Products under the trade name "QM", and copolymers and mixtures thereof, of which carbomer is preferred. Examples of suitable acrylate copolymers include, but are not limited to, those available under the trade name " 33" Acrylates copolymer available from Rohm & Haas under the trade name "Structure Plus" Acrylates / aminoacrylate copolymer available from National Starch & Chemical Company under the trade name "Structure 2001" Acrylates / steareth-20 itaconate copolymer available from National Starch & Chemical Company under the trade name "Structure 3001" Acrylates / cetoeth-20 itaconate copolymer available from National Starch & Chemical Company under the trade name " 22" acrylates / steareth-20 methacrylate copolymer available from Rohm & Haas, and copolymers and mixtures thereof. Carbopol EDT 2020 is a component belonging to the class of "carbomer interpolymer thickeners" and can be used in the present invention. When included, the thickener can be present in an amount of from about 0.05% to about 0.50% by weight of the cleaning composition, or from about 0.12% to about 0.18% by weight of the cleaning composition.

[0058] The cleaning composition may also include a buffer. Suitable buffers may include, for example, citrate buffers, phosphate buffers, lactate buffers, gluconate buffers, and sodium hydroxide. One or more buffers may be present in any amount required to achieve the desired pH. The buffer may be a blend of 20% sodium hydroxide and water or other solvent. When a buffer is included, the buffer may be present in an amount of about 0.01% to about 0.5%, and more desirably about 0.2%, by weight of the cleaning composition.

[0059] The emollient composition may be formed separately from other additional components, or may include an emollient composition formed with other additional components other than a carrier (eg, water) to form a concentrated composition. The concentrated composition may be added to a carrier (eg, water) alone.

[0060] The cleaning composition may comprise, for example, about 30% of the emollient composition, about 40% of a surfactant, and about 30% of water, by weight of the cleaning composition.

[0061] Cleaning compositions and emollient compositions described herein can be used to remove various beauty (i.e., makeup) products from the user's skin, and can be used to effectively remove mascara, foundation, lipstick and eyeliner, and there will be no residual heavy or greasy residue. Because mascara deposits high levels of film formers and contains relatively high levels of hydrophobic materials, mascara is a well-known cosmetic material that is difficult to remove from the skin. In addition, mascara contains high levels of carbon black pigments, which makes it appear dark. In addition, since mascara is usually applied to the eye or eyelashes, cleaning requires gentle, low pressure and non-planar application. Eyeliner presents its own difficulty in removal because it contains titanium dioxide, iron oxide, mica, silicon dioxide and higher concentrations of pigments / colorants, which may be more difficult to remove. In addition, like mascara, eyeliner is often applied to the eye or eye area, and cleaning requires gentle, lower pressure and non-planar application. Foundation also has some difficulties because it is usually an emulsion and can contain silicone, which causes it to remain on the skin. Today's cosmetics are intended for "24-hour" use, where the makeup remains on the user's skin for an extended period of time. These "long-wear" and waterproof makeups have a high transfer resistance, making them difficult to remove.

[0062] It is particularly desirable to provide a material that effectively and fully removes sufficient amounts of these three cosmetic materials (mascara, foundation and lipstick). In addition, it is desirable to provide a composition that does not leave oily or greasy residues on the surface of the skin, because such oily cleansers can be difficult to remove and leave a sense of uncleanliness to the user. In addition, it is useful that the cleaning composition provides low or no irritation to the skin, especially the eyes. It is also desirable to bring a soft and pleasant feeling to the user's skin during and after use.

[0082] The above-mentioned cleaning compositions can be prepared by the following steps: in a suitable container, the desired components are combined, and in any conventional mixing device well known in the art, such as a mechanical stirring propeller, a paddle, etc., they are mixed under any desired conditions. Processing may include the following separate steps: forming an emollient composition, and adding one or more additional components to the emollient composition to prepare the cleaning compositions. Alternatively, the cleaning compositions can be formed by combining the components in any desired order, wherein the order of addition of the components is variable. Alternatively, the cleaning compositions can be formed in the following manner: except water, combining the components in any order, and then separately adding water to the premix to form the cleaning compositions.

[0083] The cleansing composition can be provided in a container in the form of a liquid, gel, balm or cream, from which it can be applied to the skin by the user by hand or with a cloth, wipe, sheet or other device, or alternatively, the cleansing composition can be embedded or soaked into a wipe or multiple sheets or wipes, from which the cleansing composition can be applied to the skin via a wipe sheet, wipe or other device.

[0084] Since the cleaning composition will be applied to the face and is expected to be used to remove cosmetic materials, it may be expected that the composition will be soaked in a sheet or wipe and provided to the user in this form. The user then takes out the soaked wipe from a suitable airtight package and applies it directly to the skin. Therefore, the system or packaging may include a plurality of wipes in a resealable package, each of which has been soaked in the cleaning composition of the present invention or otherwise comprises the cleaning composition of the present invention. In other aspects, a separate wipe may be contained in its own airtight package or container, wherein the package may be discarded after using the wipe contained therein. The wipe is desirably disposable and comprises a degradable component, thereby making them environmentally friendly and harmless. The wipe material may include, for example, natural, biodegradable or synthetic fibers or filaments (some examples of which include: wool, silk, jute, hemp, cotton, linen, sisal or ramie) or synthetics (some examples of which include: rayon, cellulose esters, polyethylene derivatives, polyolefins (such as polyethylene and polypropylene), polyamides (such as nylon 6, nylon 6,6), or polyesters (such as polyethylene terephthalate and polybutylene terephthalate)), or combinations thereof. These nonwoven materials are generally described in INDA "NONWOVENFABRICS HANDBOOK" (1999) on nonwoven substrates and methods of making them. One particular substrate that may be useful is an embossed spunlace nonwoven 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 is generally about 20 g / m2 to about 500 g / m2, for example about 50 g / m2 to about 150 g / m2. The wipe substrate can have any desired size and can have any desired area, including about 2 inches-10 inches long and about 2 inches-10 inches wide, more desirably about 7 inches-8 inches long and about 7 inches-8 inches wide. Other suitable wipe materials include those described in EP 1 283 019 B1, U.S. Patent No. 9,622,944 and U.S. Patent Application No. 2016 / 0367102, and the entire disclosure of each of these patents is incorporated herein by reference in its entirety.

[0085] The composition may be provided to the user in a liquid, balm or gel dispensing bottle or container, wherein the user applies the composition by hand, or applies the composition to a wipe or other applicator, and the user uses the applicator with the composition applied to clean the skin. The composition may be sold individually in a dispensing bottle, or may be sold in a kit, wherein the packaging includes a dispensing bottle with the composition therein and a plurality of applicator devices (such as wipes or balls).

[0086] The present invention includes not only the above-mentioned cleaning compositions, but also methods for using the above-mentioned cleaning compositions. The method includes applying an effective amount of the composition to the skin (including facial skin and near-eye skin), and cleaning the skin with the composition. The composition can be applied to the skin by hand or by using an applicator (such as a sheet, a wet wipe, a sponge, a brush, etc.). The composition can be applied when the skin is wet or dry, and can be wiped off the skin, rinsed off the skin, or the skin can be dried after the composition is applied. It is particularly desirable to apply the composition to the skin via a pre-soaked wipe and dry it from the skin without further washing or cleaning by the user. The user can discard the used wipe. The invention described herein can be implemented in the absence of any component, ingredient or step not specifically disclosed herein, or may include additional components or steps not explicitly disclosed herein.

[0087] As noted above, the present invention relates to compositions that can be used to effectively and efficiently clean a variety of cosmetics from the surface of a user's skin. The compositions of the present invention should be able to effectively remove, for example, foundation, lipstick, eye shadow, lip liner, eyebrow pencil, makeup, pomade, rouge mascara, and eyeliner. In addition, the compositions of the present invention can be substantially free of silicone, if not completely free of silicone.

[0088] The invention may be better understood through the following examples, which are illustrative in nature and are not intended to limit any specific combination of elements.

[0089] Example

[0090] The following examples describe the formation of compositions that can be used alone or as part of a cleansing composition for cleaning various cosmetic materials from the user's skin. The method used to evaluate the cleaning efficiency of the makeup remover was a combination of mechanical cleaning with a texture analyzer, a controlled light image capture system, and an image analysis system with Matlab.

[0091] The texture analyzer used in these examples is called a texture analyzer, which provides reproducible mechanical movement to clean dirty model surfaces with a makeup remover product. The texture analyzer considers force, distance and time simultaneously. The speed can be fixed and then the change in force can be measured, or the displacement can be controlled to maintain a constant force. For this purpose, the device has a force capturer.

[0092] The texture analyzer used in these examples is called TA.XT-plus, purchased from Stable Micro Systems, UK. The TA.XT-plus was used for all measurements described herein. The software used was TextureExponent32, purchased from Stable Micro Systems, Cardiff, UK.

[0093] For the tribological measurements the following equipment was used: tribological device HFS (Horizontal Tribological System, Stable Microsystem) and a mobile device with a weight of 204 g and dimensions of 15×8 cm, which was fixed to the texture analyzer with screws.

[0094] PMMA (polymethyl methacrylate) sample plates (80 x 80 cm) were used to simulate the skin support. Other materials such as Bioskin plates (Beaulax Co ltd, Saitama, Japan), ABS (acrylonitrile butadiene styrene), PVC, HDPE can also be used if necessary.

[0095] In order to fix the sample plate, a solid support (PLA, polylactic acid) was made by 3D printing. The solid support was fixed on the tray of the friction device and fixed with tape so that it would not move when the movable device moved back and forth on top of it.

[0096] Each sample described in this article was analyzed using a Canon camera and its lens (Nikon D90 (Nikon Corp Japan) + Nikon AF MICRONIKKOR 105mm1:2.8D). It was positioned so that it could take pictures of the cleaning test. It was held in place with a camera arm (angle 145°). A photography chamber (80×80×80 cm) containing 2 LEDs was used to optimize the quality of the pictures. The texture analyzer and camera were placed inside.

[0097] For these tests, the cosmetic panels were prepared as follows:

[0098] o The film applicator (100 mm BEVS 1806B / 100 BEVS INDUSTRIAL CO. LIMITED, Guangzhou, China) was fixed on the laboratory bench with double-sided tape;

[0099] ○Weigh the PMMA plate;

[0100] ○ On the PMMA plate, a template paper with a circular hole (2.5 cm in diameter) was pasted in the middle;

[0101] ○ Fill the hole with makeup;

[0102] ○ Adjust the height of the film applicator according to the cosmetic product (about 2.6 mm for mascara and lipstick, about 2.45 mm for foundation, but the height may vary slightly depending on the thickness of the PMMA plate) (thickness = PMMA plate + tested cosmetic product);

[0103] ○ Pass the PMMA sheet under the film applicator;

[0104] o Remove the template paper and weigh the plate, and thus determine the mass of the cosmetic on the plate,

[0105] o Allow the plate to dry at room temperature (about 20°C) for 12 hours up to 48 hours.

[0106] For mobile calibration, it is desirable to calibrate the height of the probe with the mobile as close as possible to the friction device. The "removable support" is a friction device HFS (Horizontal Friction System, Stable Microsystem) and a mobile weighing 204 g and with dimensions 15 x 8 cm.

[0107] To measure these results, the following setup was used: a cotton pad ( cottonscience TM Expert honeycomb texture (expert honeycomb texture, 100% biodegradable natural cotton fiber; purchased from Essity SA, Belgium) is fixed on the removable support. Then, 3 mL of emollient (or emollient composition) is placed on the cotton pad, the removable support is turned over on the fixed support, and a mass of 2 kg is placed on the removable support.

[0108] The analysis of the makeup removal efficiency was performed as follows: the removable support was configured to automatically displace 70 mm. The displacement was repeated several times, depending on the type of makeup studied: 5 times for mascara and lipstick, and 2 times for foundation. Photos of the PMMA plate were taken before any movement ("before image") and at the end of the sequence of displacement of the removable support ("after image"). The photos (before / after) of each sample thus obtained were analyzed with Matlab to evaluate the cleaning efficiency of the emollient.

[0109] For mascara, the color in the before and after images is evaluated, and the average value of the color of each pixel in the circle where the makeup is applied in the "before image" and "after image" is given respectively (this average value is called Bval). The Bval of the "after image" is compared with the Bval of the "before image", and the ratio gives the Bratio number (Bval of the "after image" / Bval of the "before image"). Bratio is considered to be more relevant for mascara because it effectively evaluates gray shades.

[0110] For lipstick and foundation, which contain more pigmented shades than mascara, the clean panel test is considered more appropriate for evaluating cleaning ability. For each test, the clean panel value is defined as ((number of elements in the chromaticity matrix - number of non-zero elements in the chromaticity matrix) / number of elements in the chromaticity matrix) *]00.

[0111] The chromaticity matrix in the Lab color space is: a* (green to red) and b* (blue to yellow) are the second and third dimensions of the image in the lab color space, respectively.

[0112] The cosmetic products tested included the following:

[0113] ○Mascara: Neutrogena hydroboost plumping mascara waterproof

[0114] ○ Lipstick: L'Oréal color rich n°297 Red passion (L'Oréal color rich lipstick No. 297 Red passion)

[0115] ○ Foundation: L'Oréal accord parfait 3D beige doré (L'Oréal accord parfait 3D three-dimensional light-sensitive foundation beige gold)

[0116] The various emollients tested in the following examples included:

[0117] ○ Schercemol PGML; INCI name: Propylene glycol laurate; Supplier: Lubrizol

[0118] ○Schercemol IDO; INCI name: Isodecyl Oleate; Supplier: Lubrizol

[0119] ○Estol 1514; INCI name: Isopropyl myristate; Supplier: Croda

[0120] ○Cegesoft PFO; INCI name: passionflower oil; Supplier: BASF

[0121] ○Crodamar 227; INCI name: Decyl Isostearate; Supplier: Croda

[0122] ○Tegosoft DC MB; INCI name: Decyl Cocoate; Supplier: Evonik

[0123] ○Arlamol HD; INCI name: Isohexadecane; Supplier: Croda

[0124] ○Apricot kernel organic cold pressed virgin oil; INCI name: Prunus armeniaca kernel oil; Supplier: GreenTech

[0125] Separate emollients

[0126] In the first set of experiments, the cleansing performance of a group of selected emollients was investigated. The emollients were tested individually in the form received from the supplier (ie, not combined with other emollients or in a formulation).

[0127] As described above, Bval and Bratio measurements were obtained for mascaras, and clear plate measurements were obtained for lipsticks and foundations.

[0128] 1. Mascara

[0129] The Bval and Bratio values ​​of selected emollients with respect to mascara stains are shown below in Table 1. For mascara, the Bratio value is considered to be a relative indicator of the ability to remove mascara from a surface, with higher Bratio values ​​indicating higher cleaning efficacy scores.

[0130] Table 1: Bratio and Bval for mascara removal

[0131]

[0132]

[0133] As can be seen from Table 1, Estol 1 514 has the highest Braio value for removing mascara stains. Other relevant emollients identified in the above table include Arlamol HD, Tegosoft DC MB and Schercemol IDO.

[0134] 2. Lipstick

[0135] The Clean Plate values ​​for selected emollients on lipstick stains are shown below in Table 2. Higher Clean Plate values ​​are considered to be associated with better cleaning properties.

[0136] Table 2: Clean Plate Values ​​- Lipstick

[0137]

[0138] As can be seen from Table 2, Crodamar 227 was found to be the most promising emollient for removing lipstick stains. Other related emollients such as Schercemol IDO, Prunus armeniaca, Estol 1514 and Arlamol HD showed comparable results.

[0139] 3. Foundation

[0140] The Clean Plate values ​​for selected emollients on foundation stains are shown below in Table 3. Higher Clean Plate values ​​are believed to be associated with better cleaning properties.

[0141] Table 3: Clean Plate Values ​​- Foundation

[0142]

[0143] As can be seen from Table 3; Estol 1514, Arlamol HD, Schercemol PGML, Tegosoft DC MB and Schercemol IDO all showed promising foundation stain cleaning performance.

[0144] Combination of emollients

[0145] In a second set of experiments, the cleaning performance of emollient compositions containing combinations of emollients was investigated to see if a combination could be identified that showed promising results on all three types of makeup stains (mascara, lipstick, and foundation). In the emollient compositions tested, the emollient ratios were expressed in weight %.

[0146] Many combinations were tested and the data presented here focus on the most promising results, including a mixture of Tegosoft DC MB, Estol 1514 and Schercemol PGML.

[0147] 1. Mascara

[0148] The Bratio values ​​of emollient compositions comprising different ratios of the three selected emollients with respect to mascara stains are shown in Table 4.

[0149] Table 4: Emollient Combinations – Mascara

[0150]

[0151]

[0152] For the mixture of the three selected emollients, a Bratio value of up to 2.93 was obtained. In comparison, referring to the table above, the Bratio values ​​of the three emollients used alone were 2.46 (Estoll 514), 2.32 (Tegosoft DC MB) and 1.75 (Schercemol PGML). It was therefore determined that the cleaning efficacy of mascara stains was slightly improved compared to the individual emollients. In particular, when the amounts of the three emollients were approximately equal, or when a higher amount of Schercemol PGML was used, an improved cleaning efficacy was observed.

[0153] 2. Lipstick

[0154] The cleaning panel values ​​for mixtures containing different ratios of the three selected emollients on lipstick stains are shown in Table 5.

[0155] Table 5: Combination of Emollients: Lipstick

[0156]

[0157] For the mixture of 3 kinds of selected emollients, a cleaning plate value of up to 91.88 was obtained. In contrast, and with reference to the above table, the cleaning plate values ​​of these 3 emollients used alone were 49.74 (Estol 1514), 43.77 (Tegosoft DC MB) and 36.82 (Schercemol PGML). Compared with independent emollients, it is observed that the cleaning efficacy of lipstick stains is greatly improved. The cleaning efficacy of the mixture of each ratio is higher than the independent efficacy of these emollients respectively. In addition, it is found that the combination when the amount of Estol 1514 is higher or when the amount of Tegosoft DC MB is higher is better than the most effective emollient identified in the first group of experiments: Crodamar 227 (69.27). Even when the amount of Schercemol PGML is the highest, or when each amount is roughly equal, the cleaning efficacy is also similar to independent Crodamar 227.

[0158] Surprisingly, the cleansing efficacy of the medium potency emollient (Estol 1514) was enhanced by the 2 other emollients that showed the lowest efficacy.

[0159] 3. Foundation

[0160] The cleaning board values ​​for mixtures containing different ratios of the 3 selected emollients on foundation stains are shown in Table 7.

[0161] Table 6: Combinations of emollients: foundation

[0162]

[0163] When the amounts of the three selected emollients were approximately equal, a cleaning plate value of up to 94.8 was obtained for the mixture of the three selected emollients. As can be seen above, the cleaning plate values ​​of the three emollients used alone were similar, ranging from 99.3 (Estol 1514) to 94.5 (Tegosoft DC MB). The cleaning efficacy of the individual emollients on the foundation was quite high, so the cleaning efficacy of the blended combination was comparable to that of the individual emollients in terms of removing foundation stains.

[0164] in conclusion

[0165] Based on the above individual cleaning tests and the cleaning tests of the three emollients blended together, it can be seen that the combination of Tegosoft DC MB, Estol 1514 and Schercemol PGML shows excellent cleaning results for removing makeup stains including mascara, lipstick and foundation. The blended combination of emollients has improved results in removing lipstick and mascara compared to the emollients used alone. The cleaning results of the blended combination in removing foundation are consistent with the observations made for the emollients used alone.

[0166] Specifically, the cleansing results of the blended combination of emollients in removing lipstick were surprisingly high compared to the results of the emollients used alone. Thus, it was determined that the combination of these three emollients was more effective in removing makeup components overall.
