Description

[Technical Field]

[0001] The present invention relates to a method for cleansing the face by using a composition comprising at least one polysaccharide. [Background technology]

[0002] Cleansing the skin is very important for facial care, and must be as effective as possible, because greasy residues, such as excess sebum, residues of daily used cosmetics, and makeup products, especially water-resistant products, tend to accumulate in skin folds such as wrinkles and clog skin pores, which can lead to the appearance of pimples.

[0003] Therefore, in the cosmetics field, cleansing products are widely used to cleanse keratinous materials, such as the skin, and in particular to remove make-up on keratinous materials.

[0004] Some cleansing products contain small particles called "scrubs" that can contribute to the physical removal of keratinous materials, such as dirt or make-up, from the skin.

[0005] Furthermore, environmentally friendly cosmetic formulations, which are designed and developed with environmental issues in mind, have become an important goal in efforts to address global issues.

[0006] It is therefore essential to propose more sustainable compositions, preparation methods and ingredients to meet these environmental challenges.

[0007] In this context, it is important to develop new beauty methods using cosmetic compositions, such as cleansing compositions, with a better carbon footprint, in particular by promoting the use of renewable raw materials and / or materials with a good index of naturalness and / or materials of natural origin.

[0008] There is a constant need to develop new cleansing methods that can provide good cleansing efficiency. [Prior art documents] [Patent documents]

[0026] [Figure 1] FIG. 1 illustrates an example of a method according to the present invention. DETAILED DESCRIPTION OF THE INVENTION

[0027] After extensive research, the present inventors have discovered a new method for cleansing the face that can provide good cleansing efficiency.

[0028] Accordingly, one aspect of the present invention is a method for cleansing the face, comprising: (1) providing 5 g or less, preferably 4 g or less, more preferably 3 g or less of (a) a composition comprising at least one polysaccharide; (2) applying the composition to the face; (3) optionally applying the composition to facial eyelashes; (4) optionally leaving the composition on the face for preferably at least 3 seconds, more preferably at least 4 seconds, and even more preferably at least 5 seconds; (5) massaging the face in a circular motion; (6) removing the composition from the face; The method includes:

[0029] The method according to the invention is capable of producing agglomerates, which may be in the form of noodles, which are generated by massaging the face and which are derived from (a) polysaccharides present in the composition applied to the face.

[0030] The aggregates may be in the form of noodles, but may also be produced by rubbing a composition comprising (a) a polysaccharide on the face.

[0031] The agglomerates, which may be in the form of noodles, produced by the method according to the present invention can function as "scrubbing" particles. Thus, the agglomerates can contribute to exfoliating the surface of the face, for example, the surface of the stratum corneum of the face. Thus, the agglomerates, which may be in the form of noodles, can contribute to effectively removing dirt or makeup from the face. Therefore, the method according to the present invention is suitable for cleansing the face.

[0032] The agglomerates formed by the method according to the invention, which may be in the form of noodles, can be produced within a reasonable period of time, i.e. not too long, so that the method according to the invention can provide good cleansing efficiency.

[0033] The method according to the invention also allows for the formation of aggregates, which may be in the form of noodles, relatively quickly and without excessive massaging of the facial skin, which can result in less friction and is more favourable for the facial skin.

[0034] Furthermore, the aggregates, which may be in the form of noodles, may contribute to an accelerated turnover of the surface of the facial layer, for example the surface of the stratum corneum of the face, so that the method according to the invention may also provide a cooling sensation.

[0035] Furthermore, the agglomerates produced by the method according to the invention, which may be in the form of noodles, may be soft, so that the method according to the invention may also provide a pleasant sensation in use.

[0036] The aggregates, which may be in the form of noodles, may be formed by (a) polysaccharides, which may be derived from natural sources, and therefore the composition used in the method according to the invention is environmentally friendly.

[0037] Hereinafter, the method according to the present invention will be described in more detail.

[0038] [method] The method for cleansing the face according to the present invention comprises: (1) providing 5 g or less, preferably 4 g or less, more preferably 3 g or less of (a) a composition comprising at least one polysaccharide; (2) applying the composition to the face; (3) optionally applying the composition to facial eyelashes; (4) optionally leaving the composition on the face for preferably at least 3 seconds, more preferably at least 4 seconds, and even more preferably at least 5 seconds; (5) massaging the face in a circular motion; (6) removing the composition from the face; Includes:

[0039] The method according to the invention may be a cosmetic method for the face.

[0040] The method according to the present invention can be characterized by the use of specific compositions in appropriate amounts in combination with an appropriate protocol defined by specific steps.

[0041] The steps involved in the method according to the invention are described below.

[0042] (Process 1) Step (1) of the method according to the invention provides (a) a composition comprising at least one polysaccharide in an amount of 5 g or less, preferably 4 g or less, more preferably 3 g or less.

[0043] It may be preferred that the amount of the composition is 0.5g or more, more preferably 1.0g or more, even more preferably 1.5g or more.

[0044] Therefore, the amount of the composition provided in step (1) can be 0.5 g to 5 g, preferably 1.0 g to 4 g, more preferably 1.5 g to 3 g.

[0045] Preferably, the composition used in the method according to the invention is taken from a container containing the composition with the hands, more preferably with dry hands, ie the hands are not wet.

[0046] More preferably, the composition used in the method according to the invention is taken from the container with at least one finger, more preferably with at least one dry finger, ie the fingers are not wet.

[0047] It is preferred that the composition be applied with dry hands, i.e., the hands are not wet, in order to rapidly form agglomerates from the composition in step (5), which may be in the form of noodles.

[0048] In a preferred embodiment, the composition is taken from a container containing the composition with at least one finger and applied to the back or palm of the hand.

[0049] In a preferred embodiment, the composition is applied to the back or palm of the hand, preferably to a dry back or palm, ie, the back or palm is not wet.

[0050] (Process 2) Step (2) of the method according to the present invention involves applying the composition provided by step (1) to the face.

[0051] The composition is preferably applied to a dry face, i.e., the face is not wet, in order to rapidly form agglomerates from the composition in step (5), which may be in the form of noodles.

[0052] It is also preferred that the composition be applied to at least the forehead, cheeks, nose and chin of the face, and more preferably, the composition be spread from the center to the outer edges of the face.

[0053] In a preferred embodiment, the user takes a portion of the provided composition on the back or palm of their hand and places it on at least the forehead, cheeks, nose and chin of the user's face, spreading the composition over their face.

[0054] In another preferred embodiment, the user takes a portion of the composition provided in the container and places it on at least the forehead, cheeks, nose and chin of the user's face, spreading the composition over the face.

[0055] By placing the composition on the forehead, cheeks, nose and chin of the face, the composition can be spread more evenly over the face.

[0056] In step (2), the composition is applied and / or spread on the face using at least one finger or at least one applicator. If necessary, the palm of the hand may also be used. The applicator may be any tool for applying or spreading the composition.

[0057] Preferably, the composition is applied and / or spread onto the face with at least one finger, more preferably with at least one dry finger, ie, the fingers are not wet.

[0058] In step (2), it is preferable to form a thin film of the composition that can be easily dried. Forming a dry thin film of the composition is preferable for quickly forming agglomerates, which may be in the form of noodles, on the face in step (5).

[0059] (Step 3) Step (3) of the method according to the present invention is an optional step for applying the composition provided by step (1) to facial eyelashes.

[0060] In step (3), the composition may be applied to the eyelashes using at least one finger or at least one applicator, which may be any tool for applying or spreading the composition, such as a brush.

[0061] If necessary, step (3) may be carried out before step (2).

[0062] (Step 4) Step (4) of the method according to the present invention is an optional step for leaving the applied facial composition in step (3) with or without step (2).

[0063] The period for which the composition is left on the face is not limited.The period for which the composition is left on the face is preferably 3 seconds or more, more preferably 4 seconds or more, and even more preferably 5 seconds or more.The period for which the composition is left on the face can be 60 minutes or less, preferably 30 minutes or less, and more preferably 15 minutes or less.

[0064] Step (4) allows the composition on the face to dry, which is preferable for quickly forming agglomerates, which may be in the form of noodles, on the face in step (5).

[0065] (Step 5) In step (5) of the method according to the present invention, the face to which the composition was applied during step (2) is massaged in circular motions.

[0066] The circular movement allows the formation of aggregates derived from the (a) polysaccharides present in the composition used in the method according to the invention.

[0067] In other words, the composition on the face can be rubbed in a circular motion to create agglomerates that can be in the form of noodles.

[0068] The agglomerates, which may be in the form of noodles, may function to remove dirt or make-up from the face.

[0069] The circular motion can be formed by any means, for example, by fingers. However, in step (5), the circular motion is preferably performed by hand, more preferably by fingers and / or palms, even more preferably by palms, especially dry palms. Agglomerates, which may be in the form of noodles, can be formed more quickly by using dry hands compared to using wet hands.

[0070] The duration of the facial massage in step (5) is not limited. The duration of the facial massage in step (5) is preferably 3 seconds or more, more preferably 4 seconds or more, and even more preferably 5 seconds or more. The duration of the facial massage in step (5) can be 45 seconds or less, preferably 30 seconds or less, and more preferably 15 seconds or less.

[0071] If necessary, in step (5), the face may be massaged with at least one interval of at least 3 seconds, preferably at least 4 seconds, more preferably at least 5 seconds, and the interval may be 30 seconds or less, preferably 20 seconds or less, more preferably 10 seconds or less.

[0072] Steps (1) to (5) may be repeated if necessary.

[0073] For example, if the user wishes to use a larger amount of the composition used in the method according to the present invention and to produce aggregates, which may be in the form of noodles, as quickly as possible, steps (1) to (5) may be repeated rather than using more than 5 g of the composition.

[0074] (Step 6) In step (6) of the method according to the present invention, the composition is removed from the face massaged in step (5).

[0075] The facial composition can be removed by any means, for example, by rubbing the face with fingers, hands, such as the palm of the hand, wiping the face with fingers, hands, such as the palm of the hand, or a wipe, such as tissue paper or a towel, or by rinsing the face with water, etc.

[0076] (gesture) FIG. 1 shows an example of a method according to the invention.

[0077] In step (1), 5 g or less of (a) a composition comprising at least one polysaccharide is provided, for example, by removing it from a container containing the composition.

[0078] In step (2), the composition is applied to the face. Preferably, the composition is applied to at least the forehead, cheeks, nose, and chin of the face. When the composition is applied to the forehead, cheeks, nose, and chin of the face, it is more preferable that the composition be spread from the center to the outer edges of the face. In Figure 1, the application and spreading are performed by the fingers. However, the palm can also be used to apply and spread the composition on the face.

[0079] In step (3), the composition is applied to the eyelashes on the face. As shown in Figure 1, application can be performed with the fingers along the direction of the eyelashes. It is preferable that the composition does not get into the eyes.

[0080] In step (4), the composition is left for a certain period of time, for example, 5 seconds or more. Step (4) allows the composition on the face to become more dry.

[0081] In step (5), the face is massaged in circular motions. In Figure 1, the circular motions are performed with the fingers. However, it is preferred to perform the circular motions with the palm of the hand in order to quickly generate agglomerates that may be in the form of noodles.

[0082] In steps (6) and (6'), the facial composition is removed from the face. In FIG. 1, in step (6) or step (6'), the facial composition is removed by wiping the face with a towel or rinsing the face with water, respectively. In step (6), it is preferable to use a damp towel. However, instead of a towel, any wiping means, such as hands and fingers, or tissue paper, can be used. In step (6'), tap water can also be used.

[0083] [Composition] The composition used in the method according to the invention comprises (a) at least one polysaccharide.

[0084] The composition used in the method according to the invention comprises: (b) at least one oil, and (c) at least one emulsifier selected from gemini surfactants, glycolipids, and mixtures thereof; It may further include.

[0085] Hereinafter, the above components (a) to (c) will be explained in detail.

[0086] (polysaccharide) The composition used in the method according to the present invention comprises (a) at least one polysaccharide. A single type of polysaccharide may be used, or two or more different types of polysaccharides may be used in combination.

[0087] In one embodiment, (a) the polysaccharide is preferably selected from polysaccharides derived from microorganisms.

[0088] According to the present invention, the term "polysaccharides of microbial origin" means polysaccharides produced by microorganisms such as bacteria.

[0089] Examples of polysaccharides derived from microorganisms include cardulan, xanthan gum, gellan gum, dextran, pullulan, sclerotium gum, and mixtures thereof.

[0090] Preferably, the microbially derived polysaccharide is selected from the group consisting of sclerotium gum, xanthan gum, and mixtures thereof.

[0091] In another embodiment, (a) the polysaccharide is preferably selected from polysaccharides derived from plants.

[0092] According to the invention, the term "polysaccharides of plant origin" means, in particular, polysaccharides obtained from the plant kingdom (plants or algae).

[0093] Examples of polysaccharides of plant origin that can be used according to the invention include, inter alia: a) algae extracts, such as alginates, carrageenans and agar-agar, and mixtures thereof. Examples of carrageenans that may be mentioned include Satiagum UTC30® and UTC10® from the company Degussa, and an alginate that may be mentioned is sodium alginate sold under the name Kelcosol® by the company ISP; b) gums, such as guar gum and its non-ionic derivatives (hydroxypropyl guar), gum arabic, glucomannan, tragacanth gum, ghatti gum, tamarind gum, karaya gum or locust bean gum; examples that may be mentioned include the guar gum sold under the name Jaguar HP105® by the company Rhodia; c) modified or unmodified starches, such as those obtained from cereals such as wheat, corn or rice, from legumes such as blonde pea, from tubers such as potato or cassava, and tapioca starch; dextrins, such as corn dextrin; examples that may be mentioned include rice starch Remy DR I® sold by the company Remy; corn starch B® from the company Rockete; potato starch modified with 2-chloroethylaminodipropionic acid and neutralized with sodium hydroxide, sold under the name Structure Solanace® by the company National Starch; and native tapioca starch powder sold under the name Tapioca pure® by the company National Starch; d) dextrin, such as corn-derived dextrin under the trademark Index® from National Starch; and A mixture of these.

[0094] The (a) polysaccharide is preferably selected from glucomannan.

[0095] Glucomannan: (a) The glucomannan as the polysaccharide can be selected from water-soluble glucomannan, water-insoluble glucomannan, and a mixture thereof. Preferably, the glucomannan is a mixture of water-soluble glucomannan and water-insoluble glucomannan.

[0096] "Water-soluble" as used herein means that the glucomannan can have a water solubility of 0.1% by mass or more, preferably 0.5% by mass or more, and more preferably 1% by mass or more, in water (pH=7) at atmospheric pressure (760 mmHg) and room temperature (25°C).

[0097] By "water-insoluble" herein is meant that the glucomannan may have a water solubility of less than 0.1% by weight in water (pH=7) at atmospheric pressure (760 mmHg) and room temperature (25°C).

[0098] Glucomannan is a large molecular weight (typically 500,000) starch composed of D-glucose and D-mannose units. <Mw グルコマンナン <2,000,000), in which D-glucose and D-mannose are linked by β-1,4-glucosidic bonds in a ratio of approximately 2:3 (1:1.6).

[0099] Glucomannan is a substantially linear polysaccharide, but may have branches approximately every 50 or 60 units. Some of the hydroxyl groups of the polysaccharide are acetylated.

[0100] Glucomannan can be found in wood, but it is also the main component of konjac gum. Therefore, glucomannan can be derived from konjac (Amorphophallus konjac), a plant in the Araceae family.

[0101] Glucomannan is naturally water-soluble. The original glucomannan obtained from konjac can be used as water-soluble glucomannan.

[0102] Water-soluble glucomannan may function as a thickening agent for the compositions used in the methods according to the present invention.

[0103] On the other hand, glucomannan can be treated to make it water-insoluble. For example, JP 2000-344801 and JP 2006-169300 disclose methods for producing water-insoluble glucomannan.

[0104] For example, water-insoluble glucomannan can be prepared by the following process: (1) dissolving glucomannan-rich powder in water to prepare a solution; (2) mixing the solution with ethanol to precipitate glucomannan; (3) adding an alkali to the resulting mixture to convert the precipitated glucomannan particles into water-insoluble irreversible hydrogel particles; (4) separating the glucomannan hydrogel particles from the liquid; (5) drying the separated hydrogel particles; (6) crushing and sieving the dried gel particles to a desired particle size; It can be prepared by

[0105] As used herein, the term "glucomannan-rich flour" refers collectively to refined konjac flour, highly purified glucomannan flour, and rapidly dissolvable konjac flour.

[0106] In step (1), the starting glucomannan-rich flour can be dissolved in water to form an aqueous solution. Because the glucomannan solution can be very viscous, its concentration can be less than 5% by weight, preferably 0.5% to 1.5% by weight.

[0107] In step (2), the solution can be mixed with ethanol, preferably by slowly adding the glucomannan solution to the ethanol while stirring, causing the glucomannan to precipitate as fibrous particles.

[0108] Since glucomannan is not soluble in ethanol or aqueous ethanol mixtures containing more than 30% ethanol by weight, the weight ratio of ethanol to glucomannan solution can be at least 3:7.

[0109] In step (3), the precipitated glucomannan particles can be reacted with alkali to produce a water-insoluble, thermally irreversible hydrogel. This reaction can be carried out by adding an alkali solution to the water-ethanol mixture containing the precipitated glucomannan. Any alkali can be used, such as sodium hydroxide, potassium hydroxide, calcium hydroxide, sodium carbonate, and potassium carbonate. Saturated limewater is preferred and is a common practice in the production of edible konjac. Unlike edible konjac, glucomannan gels while retaining its fibrous particulate form. This makes it easier to separate the gel from the liquid.

[0110] In step (4), the gel particles can be separated from the liquid, for example by centrifugation, and washed at least once with aqueous ethanol. If necessary, the washing solution may contain a non-toxic organic acid, such as acetic acid or citric acid, to neutralize excess alkali.

[0111] In step (5), the gel particles thus separated can be thoroughly dried in conventional equipment, preferably in a hot air dryer at about 105° C. or above, to remove most of the water.

[0112] In step (6), the dried gel particles can be crushed and sieved to obtain a final product having a desired size.

[0113] The water-insoluble glucomannan may be in the form of gel particles. The particle size of the water-insoluble glucomannan may be 10 to 500 microns, preferably 50 to 500 microns, and more preferably 100 to 500 microns. The particle size may be a particle size based on volume.

[0114] The water-insoluble glucomannan may be deacetylated due to the action of the alkali used during the process for preparing the water-insoluble glucomannan.

[0115] Deacetylated water-insoluble glucomannan can easily aggregate and form a gel due to hydrogen bonding between the hydroxyl groups of the glucomannan molecules.

[0116] When an alkaline earth metal hydroxide, such as Ca(OH)2, or a salt thereof is used as the alkali, the water-insoluble glucomannan contains a divalent alkaline earth metal ion, such as Ca 2+ can be crosslinked by

[0117] As glucomannan, commercially available products such as the Konjac flour series sold by BLG (Shanghai Brilliant Gum Co., Ltd.) in China and Propol (registered trademark) ISLB sold by Shimizu Chemical Co., Ltd. in Japan may be used.

[0118] (a) The polysaccharide is preferably selected from polysaccharides derived from microorganisms and / or plants, preferably from the group consisting of curdlan, xanthan gum, gellan gum, dextran, pullulan, sclerotium gum, agar, tamarind gum, glucomannan, and mixtures thereof, more preferably from the group consisting of agar, tamarind gum, glucomannan, and mixtures thereof.

[0119] The amount of (a) polysaccharide in the composition used in the method according to the present invention may be 0.5% by weight or more, preferably 1% by weight or more, more preferably 1.5% by weight or more, relative to the total weight of the composition.

[0120] The amount of (a) polysaccharide in the composition used in the method according to the present invention may be 15% by weight or less, preferably 10% by weight or less, more preferably 5% by weight or less, relative to the total weight of the composition.

[0121] The amount of (a) polysaccharide in the composition used in the method according to the present invention can be 0.5% by mass to 15% by mass, preferably 1% by mass to 10% by mass, and more preferably 1.5% by mass to 5% by mass, relative to the total mass of the composition.

[0122] (oil) The composition used in the method according to the present invention may comprise (b) at least one oil. A single type of oil may be used, or two or more different types of oil may be used in combination.

[0123] (b) The oil may form the fatty phase of the composition used in the method according to the invention.

[0124] Here, "oil" means a fatty compound or substance that is in the form of a liquid or paste (non-solid), preferably a liquid, at atmospheric pressure (760 mmHg) and room temperature (25°C). As oil, those commonly used in cosmetics can be used alone or in combination.

[0125] (b) The oil may be volatile or non-volatile.

[0126] (b) The oil may be a non-polar oil such as a hydrocarbon oil or a silicone oil, or a polar oil such as a vegetable oil or an animal oil, and an ester oil or an ether oil, or a mixture thereof.

[0127] (b) The oil may be selected from the group consisting of oils of vegetable or animal origin, synthetic oils, silicone oils and hydrocarbon oils.
