Description

Stable cleansing water that is able to remove UV filtersTechnical Field

[0001] The present invention relates to a stable cleansing water capable of removing UV filters.Background Art

[0002] Cleansing products are important for skincare and are available in various forms such as milk, aqueous gels, creams, oil-based gels, balms, oils, and sheets. While oil-based gels, balms, and oil forms of cleansing products have high cleansing ability to remove makeup and UV filters, they also tend to irritate the skin and require rinsing with water after use. Aqueous cleansing products generally offer the convenience of not needing to rinse the face after use, but they tend to have lower cleansing ability compared to other cleansing products due to their water-based formulations.

[0003] Patent Document 1: JP 7470237 B2 discloses a cleansing composition in form of a bi-continuous phase formed by the combination of ester oil, water and surfactant, but it does not contain an amphiphilic liquid. Patent Document 2: JP 6233896 B2 discloses a cleansing cosmetic comprising (A) one or more selected from the group consisting of dicarboxylic acid bis(polyoxyalkylene alkyl ether) esters and polyglyceryl- 10 (eicosanedioate / tetradecanedioate), (B) polyglyceryl fatty acid esters, and (C) water, but it does not contain an anionic surfactant.

[0004] The targets for cleansing include mascara, UV filters, foundation, eyeshadow, powder, etc., with UV filters being one of the more difficult types of makeup to remove. Conventional aqueous cleansing products have been particularly ineffective at removing UV filters. Therefore, the object of the present invention is to provide an aqueous cleansing product capable of removing UV filters.Summary of the invention

[0005] So, the present invention provides an aqueous cleansing composition comprising: A) one or more types of polyglycerin fatty acid esters derived from fatty acids with 8 to 10 carbon atoms and having an HLB value of 10 to 15, B) a cyclic ether or a polyglycerin ester having a dicarboxylic acid with 14 to 28 carbon atoms, C) an anionic surfactant, and D) water, wherein component B is not polyglycerin fatty acid esters.By ‘aqueous cleansing composition’ in the present invention, it means a cleansing composition comprises water and less than 5% of oil component, preferably less than 2% of oil component and even more preferably less than 1% of oil component. In a particular embodiment, the aqueous cleansing composition does not contain an oil component. In a particular embodiment, the content of component D water ranges from 75 to 98% by mass, in particular 83 to 98% by mass based on the total mass of the composition.In a particular embodiment, the total amount of component A ranges from 1 to 5% by mass based on the total mass of the composition and the content of component D ranges from 75 to 98% bu mass based on the total mass of the composition. The present invention also provides a cosmetic process for cleansing the skin, comprising the application of an aqueous cleansing product according to the invention, onto the skin.

[0006] The aqueous cleansing composition according to the present invention can remove UV filters. Additionally, the aqueous cleansing composition according to the present invention does not require rinsing with water after use.Detailed description

[0007] The embodiments of the present invention will be described in detail below.

[0008] One embodiment of the present invention is an aqueous cleansing compositioncomprising: A) one or more types of polyglycerin fatty acid esters derived from fatty acids with 8 to 10 carbon atoms and having an HLB value of 10 to 15, B) a cyclic ether or a polyglycerin ester having a dicarboxylic acid with 14 to 28 carbon atoms, C) an anionic surfactant, and D) water, wherein component B is not polyglycerin fatty acid esters. In a particular embodiment, the total amount of component A ranges from 1 to 5% by mass based on the total mass of the composition, and the content of component D ranges from 75 to 98% by mass, preferably 83 to 98% by mass based on the total mass of the composition.

[0009] (Composition A)Component A in the present invention is a polyglycerin fatty acid ester. Polyglycerin fatty acid esters are esters of polyglycerin and fatty acids, and there are no particular restrictions as long as the fatty acids have 8 to 10 carbon atoms and the HLB value is 10 to 15.

[0010] In a particular embodiment, the HLB value of the polyglycerin fatty acid ester ranges from 10 to 15, and may be 11 to 15, 12 to 15, 13 to 15, 14 to 15, 11 to 14, 12 to 14, 13 to 14, 12 to 14, 13 to 14, or 12 to 13. The HLB value of the polyglycerin fatty acid ester can vary depending on the average degree of polymerization of the polyglycerin and the type of fatty acid. In this specification, the HLB value may be a value measured by the Griffin method. If the HLB value is within the above range, the composition can exhibit superior cleansing ability and is more appropriate for removing UV filters.

[0011] Polyglycerin has a structure in which a plurality of glycerin units are ether-bonded and has a plurality of hydroxy groups. The degree of polymerization of polyglycerin is not particularly limited as long as the HLB value of the polyglycerin fatty acid ester falls within the range of 10 to 15. For example, the degree of polymerization of polyglycerin may be 4 to 9, 5 to 9, 6 to 9, 7 to 9, 8 to 9, 4 to 8, 5 to8, 6 to 8, 7 to 8, 4 to 7, 5 to 7, 6 to 7, 4 to 6, 5 to 6, or 4 to 5. One or more hydroxy groups in the polyglycerin fatty acid ester are bonded with fatty acids through an ester bond formation.

[0012] The fatty acids may be saturated or unsaturated fatty acids with 7 to 10 carbon atoms. Specific examples of fatty acids include octanoic acid (caprylic acid), nonanoic acid (pelargonic acid), and decanoic acid (capric acid). When two or more fatty acids are bonded to one molecule of polyglycerin, the fatty acids may be the same or different.

[0013] Specific examples of polyglycerin fatty acid esters include polyglyceryl-4 caprylate, polyglyceryl-5 caprylate, polyglyceryl-6 caprylate, polyglyceryl-7 caprylate, polyglyceryl-8 caprylate, polyglyceryl-9 caprylate, polyglyceryl-4 pelargonate, polyglyceryl-5 pelargonate, polyglyceryl-6 pelargonate, polyglyceryl-7 pelargonate, polyglyceryl-3 caprate, polyglyceryl-4 caprate, polyglyceryl-5 caprate, and polyglyceryl-6 caprate.

[0014] The polyglycerin fatty acid ester may be used singly or in a combination of two or more types. In a particular embodiment, component A consists of two or more types of the polyglycerin fatty acid esters. When combining two or more types of polyglycerin fatty acid esters, it is preferable that the mixed HLB value falls within the range of 13 to 15.

[0015] In this specification, the "mixed HLB value" is the weighted average of the HLB values of each polyglycerin fatty acid ester calculated from the following formula:HLB = 20(1 - S / A)wherein S is the saponification value of the polyglycerin fatty acid ester, and A is the neutralization value of the fatty acid as a raw material.

[0016] In a particular embodiment, the total amount of component A ranges from 1 to5% by mass based on the total mass of the aqueous cleansing composition, and may be 1 to 4.5% by mass, 1 to 4% by mass, 1 to 3.5% by mass, 1 to 3% by mass, 1.5 to 4.5% by mass, 1.5 to 4% by mass, 1.5 to 3.5% by mass, 1.5 to 3% by mass, 2 to 5% by mass, 2 to 4.5% by mass, 2 to 4% by mass, 2 to 3.5% by mass, 2 to 3% by mass, 2.5 to 5% by mass, 2.5 to 4.5% by mass, 2.3 to 4.5% by mass, 2.3 to 4% by mass, 2.3 to 3.5% by mass, 2.3 to 3% by mass, 2.5 to 5% by mass, 2.5 to 4.5% by mass, 2.5 to 4% by mass, 2.5 to 3.5% by mass, 2.5 to 3% by mass, 3 to 5% by mass, 3 to 4.5% by mass, 3 to 4% by mass, 3.5 to 5% by mass, 3.5 to 4.5% by mass, or 3.5 to 4% by mass. When the total content of component A is within the above range, the user can feel even less of an oily texture even without rinsing after washing their face.

[0017] (Component B)Component B in the present invention is a cyclic ether or a polyglycerin ester having a dicarboxylic acid with 14 to 28 carbon atoms. The composition of the invention comprising component B, has higher translucency and is preferably transparent. Additionally, the composition comprising component B tends to have superior cleansing ability.

[0018] A cyclic ether is an ether that forms a ring structure through at least one oxygen atom (oxy atom), and the number of ring structures may be one or more. The cyclic ether is preferably a 5- to 6-membered ring cyclic ether, and may be a fused cyclic ether such as a bicyclic ether or a tricyclic ether. For example, the cyclic ether may be an optionally substituted tetrahydrofuran, an optionally substituted tetrahydropyran, or an optionally substituted isosorbide (also known as 1,4:3,6-dianhydro-D-glucitol). The cyclic ether may be substituted with one or more groups selected from halogen atom, C1-6alkyl group, and C1-6alkoxy group. Examples of halogen atoms include fluorine, chlorine, and bromine atoms. Examples of C1-6alkyl group include methyl group, ethyl group, 1-propyl group, 2-propyl group, 1-butyl group, and 2-butyl group.Examples of C1-6alkoxy group include methoxy group, ethoxy group, 1-propoxy group, 2-propoxy group, 1-butoxy group, and 2-butoxy group.

[0019] Apolyglycerin ester is a compound in which polyglycerin and a dicarboxylic acid with 14 to 28 carbon atoms form an ester bond, and it is not a polyglycerin fatty acid ester as in component A. The average degree of polymerization of polyglycerin may be, for example, 6 to 15, 7 to 15, 8 to 15, 9 to 15, 10 to 15, 11 to 15, 12 to 15, 13 to 15, 14 to 15, 6 to 14, 7 to 14, 8 to 14, 9 to 14, 10 to 14, 11 to 14, 12 to 14, 13 to 14, 6 to 13, 7 to 13, 8 to 13, 9 to 13, 10 to 13, 11 to 13, 12 to 13, 6 to 12, 7 to 12, 8 to 12, 9 to 12, 10 to 12, 11 to 12, 6 to 11, 7 to 11, 8 to 11, 9 to 11, 10 to 11, 6 to 10, 7 to 10, 8 to 10, 9 to 10, 6 to 9, 7 to 9, 8 to 9, 6 to 8, 7 to 8, or 6 to 7. The average degree of polymerization of polyglycerin can be calculated from the hydroxy value.A = 56.1 × 1000 / Hydroxy valueAverage degree of polymerization = (2 × A - 18.0) / (74.1 - A)

[0022] In a particular embodiment, the content of component B ranges from 0.2 to 3% by mass, 0.2 to 2.5% by mass, 0.2 to 2% by mass, 0.2 to 1.5% by mass, 0.2 to 1.4% by mass, 0.2 to 1.3% by mass, 0.2 to 1.2% by mass, 0.2 to 1.1% by mass, 0.2 to 1% by mass, 0.3 to 2.5% by mass, 0.3 to 2% by mass, 0.3 to 1.5% by mass, 0.3 to 1.4% by mass, 0.3 to 1.3% by mass, 0.3 to 1.2% by mass, 0.3 to 1.1% by mass, 0.3 to 1% by mass, 0.4 to 2.5% by mass, 0.4 to 2% by mass, 0.4 to 1.5% by mass, 0.4 to1.4% by mass, 0.4 to 1.3% by mass, 0.4 to 1.2% by mass, 0.4 to 1.1% by mass, or 0.4 to 1% by mass, based on the total mass of the aqueous cleansing composition. In a preferred embodiment, the content of component B ranges from 0.2 to 3% by mass based on the total mass of the composition. When the content of component B is 3% by mass or less, the composition exhibits further improved stability.

[0023] (Component C)Component C in the present invention is an anionic surfactant.

Examples of anionic surfactants include carboxylic acid-based surfactants, sulfate-based surfactants, sulfonic acid-based surfactants, peptide-based surfactants, acyl amino acid-based surfactants, lactic acidbased surfactants, and mixtures thereof. The composition of the invention comprising an anionic surfactant has higher translucency and is preferably transparent. It also has higher stability, is less prone to separation into aqueous and oil phases, has superior aesthetic appeal as a commercial product, and would be usable for a longer period.

In a particular embodiment, the content of component D ranges from 83 to 98% by mass based on the total mass of the aqueous cleansing composition.

[0033] (Optional Components)The composition according to the present invention may comprise optional components other than the above-mentioned components A to D. The optional components can be any components that can be used in cosmetics, such as alcohols, thickeners, neutralizers, preservatives, buffers, coloring agents, chelating agents, fragrances, plant extracts, and vitamins. Examples of alcohols include glycerin, propylene glycol, butylene glycol, pentylene glycol, and mixtures thereof. Examplesof thickeners include acrylic polymers, polysaccharides such as xanthan gum, cellulose gum, hyaluronic acid, and mixtures thereof. Examples of buffers include a citric acid buffer and a phosphate buffer.

[0034] In a particular embodiment, the composition is not in the form of an emulsion. There are two types of emulsions: oil-in-water emulsions and water-in-oil emulsions. However, the composition according to the present invention does not form either type of emulsion and can form a bi-continuous phase. In a particular embodiment, the aqueous cleansing composition of the invention forms a bi-continuous phase.

[0035] Generally, there are two known types of bi-continuous phases: one consisting of several dozen % by mass of nonionic surfactants and oil components, and the other consisting of a few % by mass of specific nonionic surfactants and oil components. The former can remove UV filters but gives an oily feel and requires rinsing the face with water after use. The latter does not require rinsing the face with water after use but has insufficient cleansing power to remove UV filters. Advantageously, the composition according to the present invention forms a bi-continuous phase even without containing oil components, thereby achieving both high cleansing ability based on the formation of the bi-continuous phase and the benefit of not requiring rinsing with water after use.

[0036] In a particular embodiment, the composition according to the present invention has a highly transparent appearance, preferably being transparent. In this specification, "transparency" means that when the composition is filled into a container (e.g., a spectroscopic quartz cell with a thickness of 5 mm) and irradiated with infrared light at 650 nm from the side, it shows a transmittance of 90 to 100%. The composition according to the present invention preferably shows a transmittance of 90 to 100%, 95 to 100%, or 97 to 100%. A transparent composition is aesthetically superior as a product and can appear more attractive when displayed.

[0037] In a particular embodiment, the composition according to the present invention exhibits excellent stability. In this specification, "stability" means storage stability Stability is generally evaluated by a stress test, where the composition is stored at 50°C for one week to observe if it maintains its initial state. The composition according to the present invention can maintain its state even after being stored at 50°C for one week, indicating that it can withstand long-term storage.The present invention also concerns a cosmetic process for cleansing the skin, comprising the application of an aqueous cleansing composition according to the invention, onto the skin. In particular, the cosmetic process is used for removing a composition comprising UV filters, in particular lipophilic UV filters. Advantageously, the cosmetic process of the present invention does not require any step of rinsing-off the aqueous cleansing composition.EXAMPLES

[0038] The following examples and comparative examples illustrate the composition of the present invention in more detail.

[0039] (Preparation of Composition)According to the Tables 1 to 7, component A and component B and any other oilsoluble components were mixed homogeneously at 70°C. Component C and any other water-soluble components were dissolved in water (i.e. component D) at 60°C. The oil-soluble mixture comprising components A and B were added to the water-soluble solution comprising component C, and stirred. Then, the mixture was cooled to room temperature to prepare the compositions of Examples 1 to 16 according to the invention and Comparative Examples 1 to 12. In Tables 1 to 7, the numbers indicating the content mean "% by mass".

[0040] (Evaluation of Appearance)After filling the prepared compositions into containers, the appearance was visuallychecked to evaluate whether they were transparent. Additionally, a 5 mm spectroscopic quartz cell (optical path length: 5 mm) filled with each composition was set in a UV- visible spectrophotometer to measure the absorbance of infrared light and calculate the transmittance.

[0041] The results are shown in Tables 1 to 7. All of Examples 1 to 16 were transparent, while Comparative Examples 1, 4, 5, and 8 to 10 were opaque.

[0042] (Evaluation of Cleansing Power)0.015 g of a sunscreen without UV scattering agents (Sun Protection Factor(SPF): 50, Protection Grade of UVA(PA): ++++) was applied to a 2 cm × 7 cm area on the forearm and left for 10 minutes to acclimate. 1.5g of Each prepared composition was applied to a cotton pad and used to wipe off the sunscreen with 15 back-and-forth strokes. The remaining amount of sunscreen was visualized using the UV mode of the VISIA Evolution skin image analysis system. The same amount of cleansing oil, cleansing balm, and cleansing milk was used to blend the sunscreen and then rinsed with water, and similar images were obtained to compare the remaining amount of sunscreen and evaluate the cleansing ability of each composition. Specifically, the cleansing ability of the compositions in the examples and comparative examples was evaluated based on which form of cleansing product (general oil cleansing, general cleansing balm, general cleansing milk, general cleansing water) their cleansing ability was closest to. Generally, it is known that the cleansing ability is highest in the order of oil cleansing, cleansing balm, cleansing milk, and cleansing water. If the cleansing ability is equivalent to that of oil cleansing or cleansing balm, it is sufficient to remove UV filters.Cleansing abilityA: close / superior to oil cleansingB: close to oil cleansing balmC: close to cleansing milkD: close to ordinary cleansing water

[0043] The results are shown in Tables 1 to 7. The cleansing ability of Examples 1 to 16 according to the invention was equivalent to that of oil cleansing or cleansing balm, showing high cleansing ability. On the other hand, Comparative Examples 2, 3, 6, and 7 had insufficient cleansing ability to remove UV filters.

[0044] (Need for Rinsing After Cleansing)After evaluating the cleansing ability, the extent to which the composition remained on the face and whether rinsing with water was necessary were evaluated. If rinsing with water was not necessary, it was evaluated as " Y," and if necessary, it was evaluated as " N." For example, it was determined that "rinsing is necessary" if the skin feels slippery when touched with a finger, or if the hand sticks to the skin as if glue has been applied when pressing the skin with the hand after evaluating the cleansing ability.

[0045] The results are shown in Tables 1 to 7. In Examples 1 to 16 according to the invention, the composition did not remain on the face to the extent that rinsing with water was necessary, and there was no oily feel. On the other hand, Comparative Example 5 had a residual feel of the composition to the extent that rinsing with water was necessary after cleansing.

[0046] (Evaluation of Stability)After filling 50 mL of each prepared composition into a transparent glass container, they were stored for one week at 4°C or 50°C. The state of the composition before and after storage was compared to observe visually any changes of appearance. Comparative Examples 1, 4, 5, and 8 to 10, which were opaque immediately after preparation, were not evaluated.StabilityNC: Not checkedY: No changeN: Changed

[0047] The results are shown in Tables 1 to 7. Examples 1 to 16 according to the invention showed no change in the state of the composition under either 4°C or 50°C conditions.
