Description

[Technical Field]

[0001] The present invention relates to compositions for treating keratinous materials, such as skin. [Background technology]

[0002] Skin cleansing is very important for facial care.Cleansing must be as efficient as possible, because fatty residues, such as excess sebum, residues of daily used cosmetics and makeup products, especially waterproof products, tend to accumulate in skin folds, such as wrinkles, and block skin pores, which can lead to the appearance of pimples.

[0003] Therefore, in the field of cosmetics, 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 cosmetic compositions, for example new cleansing compositions with a better carbon footprint, in particular by promoting the use of renewable raw materials and / or materials with a good naturalness index and / or materials of natural origin.

[0008] There is a constant need to develop new cleansing compositions that can provide good makeup removal capabilities. [Prior art documents] [Patent documents]

[0028] The cosmetic method according to the invention may be a cosmetic method for cleansing keratinous materials, preferably for removing make-up from keratinous materials, more preferably for removing make-up from the skin or eyelashes. DETAILED DESCRIPTION OF THE INVENTION

[0029] As a result of extensive research, the present inventors have discovered that it is possible to provide a composition that can provide good makeup removal ability and a unique feel when used.

[0030] Therefore, the present invention mainly comprises: (a) at least one glucomannan, and (b) at least one oil A composition, preferably a cosmetic composition, more preferably a cosmetic composition for cleansing, comprising: The composition has an amount of (a) glucomannan of 0.5% by mass or more relative to the total mass of the composition.

[0031] The composition according to the present invention can provide good makeup removal ability, and is therefore suitable for cleansing keratinous materials, such as skin.

[0032] Furthermore, the composition according to the present invention can provide a unique sensation during use because it can generate noodle-like aggregates during use. For example, by massaging a keratinous material, such as skin, on which the composition according to the present invention is present with the fingers, the composition according to the present invention can generate noodle-like aggregates derived from (a) glucomannan. Users of the composition according to the present invention can have a pleasant experience during use.

[0033] The agglomerates, which may be noodle-like, produced by the composition according to the invention may be soft, so that the composition according to the invention may also provide a comfortable feel when used.

[0034] In addition, the noodle-shaped aggregates produced by the composition according to the present invention can function as "scrubbing" particles. Therefore, they can contribute to exfoliating the surface of keratinous materials, for example, the surface of the stratum corneum of the skin. Therefore, the noodle-shaped aggregates can contribute to efficiently removing keratinous materials, for example, dirt or makeup on the skin. In addition, the noodle-shaped aggregates can contribute to accelerating the turnover of the surface of keratinous materials, for example, the surface of the stratum corneum of the skin. Therefore, the noodle-shaped aggregates can also provide a refreshing feeling.

[0035] The aggregates, which may be noodle-shaped, produced by the composition according to the present invention may be formed by (a) glucomannan, which may be derived from natural sources, and therefore the composition according to the present invention is environmentally friendly.

[0036] The above-mentioned effects and advantages provided by the composition according to the present invention can also be applied to the cosmetic method and use according to the present invention.

[0037] The present invention will be described in detail below.

[0038] [Composition] One aspect of the present invention is (a) at least one glucomannan, and (b) at least one oil A composition, preferably a cosmetic composition, more preferably a cosmetic composition for cleansing, comprising: The composition has an amount of (a) glucomannan of 0.5% by mass or more relative to the total mass of the composition.

[0039] (Glucomannan) The composition according to the present invention comprises (a) at least one type of glucomannan. A single type of glucomannan may be used, or two or more different types of glucomannan may be used in combination.

[0040] The (a) glucomannan may be selected from water-soluble glucomannan, water-insoluble glucomannan, and mixtures thereof. Preferably, the (a) glucomannan is a mixture of water-soluble glucomannan and water-insoluble glucomannan.

[0041] By "water-soluble" herein is meant that (a) 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).

[0042] By "water-insoluble" herein is meant that (a) 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).

[0043] Glucomannan is a high molecular weight (typically 500,000) starch-based sugar composed of D-glucose and D-mannose units, with the D-glucose and D-mannose units linked together by β-1,4-glycosidic bonds in a ratio of about 2:3 (1:1.6). <Mw glucomannan <2,000,000) polysaccharides.

[0044] 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.

[0045] Glucomannan can be found in trees and is also the main component of konjac gum. Therefore, glucomannan may be derived from konjac (Amorphophallus konjac), a plant in the Araceae family.

[0046] Glucomannan is naturally water-soluble. The original glucomannan obtained from konjac can be used as water-soluble glucomannan.

[0047] Water-soluble glucomannan may function as a thickening agent for compositions according to the present invention.

[0048] On the other hand, glucomannan can be processed to make it water insoluble. For example, JP 2000-344801 and JP 2006-169300 disclose methods for producing water insoluble glucomannan.

[0049] For example, water-insoluble glucomannan can be prepared by the following process: (1) dissolving glucomannan-rich flour in water to form 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; and (6) Crushing and sieving the dried gel particles to the desired particle size.

[0050] As used herein, the term "glucomannan-rich flour" collectively refers to refined konjac flour, purified glucomannan flour, and rapidly dissolvable konjac flour.

[0051] 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.

[0052] In step (2), the glucomannan solution can be mixed with ethanol, preferably by slowly adding the solution to the ethanol while stirring, causing the glucomannan to precipitate as fibrous particles.

[0053] Since glucomannan is not soluble in ethanol or aqueous ethanolic mixtures containing more than 30% ethanol by weight, the weight ratio of ethanol to glucomannan solution can be at least 3:7.

[0054] In step (3), the precipitated glucomannan particles can be reacted with alkali to produce a water-insoluble, thermally irreversible hydrogel. The reaction can be carried out by adding an alkali solution to a 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. As is common practice in the production of edible konjac, saturated limewater is preferred. Unlike edible konjac, glucomannan gels while retaining its fibrous particulate form. This facilitates separation of the gel from the liquid.

[0055] 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 can contain a non-toxic organic acid, such as acetic acid or citric acid, to neutralize excess alkali.

[0056] In step (5), the thus separated gel particles 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.

[0057] In step (6), the dried gel particles can be crushed and sieved to obtain a final product having a desired size.

[0058] 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. This particle size may be based on volume.

[0059] The water-insoluble glucomannan may also be deacetylated due to the action of the alkali used in the process for preparing the water-insoluble glucomannan.

[0060] Deacetylated water-insoluble glucomannan can easily aggregate to form a gel due to hydrogen bonding between the hydroxyl groups of the glucomannan molecules.

[0061] When an alkaline earth metal hydroxide, such as Ca(OH) or its salt, is used as the alkali, the water-insoluble glucomannan contains a divalent alkaline earth metal ion, such as Ca 2+ It may be cross-linked by

[0187] [Preparation] The composition according to the present invention can be prepared by mixing the essential components described above and, if necessary, the optional components described above.

[0188] The method and means for mixing the above essential components and optional components are not limited. Any conventional method and means can be used to mix the above essential components and optional components to prepare the composition according to the present invention.

[0189] [form] Compositions according to the invention may be in a variety of forms.

[0190] When the composition according to the present invention includes (c) water, in one embodiment, the composition according to the present invention may be in the form of a fluid, for example, an aqueous solution or dispersion. In this case, if the glucomannan is water-soluble, the composition according to the present invention may be a gel, since (a) the glucomannan can function as a thickener.

[0191] When the composition according to the present invention comprises (c) water and (d) an emulsifier, in another embodiment, the composition according to the present invention may be in the form of an emulsion, preferably an O / W emulsion or a W / O emulsion, more preferably an O / W emulsion.

[0192] The composition according to the present invention in the form of an O / W emulsion can comprise a dispersed fatty phase, for example an oily phase dispersed in a continuous aqueous phase. The dispersed fatty phase can be in the form of oil droplets in the aqueous phase. The composition according to the present invention is preferably in the form of an O / W gel emulsion.

[0193] An O / W composition or structure consisting of a fatty phase dispersed in an aqueous phase has an aqueous phase on the outside, and therefore, a composition according to the present invention having an O / W type composition or structure can provide a pleasant sensation when used due to the immediate refreshing feeling that the aqueous phase can provide.

[0194] On the other hand, the composition according to the present invention may have two visually distinct phases. One of the two phases is a fatty phase and the other is an aqueous phase. The two phases may be in the form of two layers. The two layers may be layered or stacked. Typically, the fatty phase or layer is present above the aqueous phase or layer, since the components in the fatty phase have a relatively lower density than water.

[0195] Compositions according to the present invention that have two visually distinct phases are sometimes referred to as "two-phase" or "biphasic" compositions.

[0196] In the composition according to the invention, if the specific gravity of the fatty phase is lower than that of the aqueous phase, the fatty phase will be present above the aqueous phase. Typically, the specific gravity of oil tends to be lower than that of water, so that at rest, the fatty phase will be present above the aqueous phase.

[0197] The two-phase composition according to the present invention can be converted into a single-phase composition by mixing, and after mixing, the composition according to the present invention may be in the form of an O / W or W / O type, preferably an O / W or W / O liquid composition, more preferably an O / W or W / O emulsion.

[0198] The two-phase composition according to the present invention has two visually distinguishable phases when not mixed. However, the two-phase composition according to the present invention can be converted into a single-phase composition by mixing it at the time of use. A single-phase composition such as an emulsion can provide good cosmetic effects such as good makeup removal ability without causing discomfort such as stickiness.

[0229] The present invention will now be described in more detail by way of examples, which should not be construed as limiting the scope of the present invention.

[0230] (Examples 1 to 3 and Comparative Examples 1 to 3) [Preparation] Each of the compositions according to Examples 1 to 3 and Comparative Examples 1 to 3 was prepared by mixing the components shown in Table 1. All figures relating to the amounts of components are based on "mass %" of the active ingredient.

[0231] [Table 1]

[0232] [evaluation] (Makeup removal ability) First, the artificial eyelashes were prepared and the initial mass of the artificial eyelashes was measured.

[0233] Second, waterproof mascara was applied to the artificial eyelashes. After the waterproof mascara was dried, the mass of the artificial eyelashes coated with the waterproof mascara was measured.

[0234] The amount of waterproof mascara on the lashes (A) was then determined by subtracting the original mass of the imitation lashes from the mass of the imitation lashes coated with waterproof mascara.

[0235] Third, the artificial eyelashes were wiped 40 times with wipes containing the same amount of each of the compositions according to Examples 1 to 3 and Comparative Examples 1 to 3. After wiping, the artificial eyelashes were washed with water and dried. The mass of the artificial eyelashes after wiping was then measured.

[0236] The amount of waterproof mascara remaining on the lashes (B) was determined by subtracting the original mass of the imitation lashes from the mass of the imitation lashes after wiping.

[0237] Make-up removal ability (%) was determined by (AB) / A.

[0238] The results are shown in Table 1.

[0239] A higher value (%) for "makeup removal ability" in Table 1 indicates a higher makeup removal ability, meaning that a greater amount of waterproof mascara was removed.

[0240] (Noodle generation) Each of the compositions according to Examples 1 to 3 and Comparative Examples 1 to 3 was applied to the hands and massaged with the fingers. The formation of noodle-like aggregates was observed and evaluated according to the following criteria. Yes: Noodles were produced. None: No noodles were produced.

[0241] The results are shown in Table 1.

[0242] (summary) Table 1 shows that the compositions according to Examples 1 to 3 can provide greater makeup removal ability than the compositions according to Comparative Examples 1 to 3, which do not contain any glucomannan, do not contain any oil, or do not contain a sufficient amount of glucomannan, respectively.

[0243] Table 1 also shows that the compositions according to Examples 1 to 3 were able to produce noodles, while the composition according to Comparative Example 1, which did not contain any glucomannan, was unable to produce noodles and did not provide good makeup removal ability.

[0244] The composition according to Comparative Example 2, which contained glucomannan, produced noodles but did not provide good make-up removal capabilities because it did not contain any oil.

[0245] The composition according to Comparative Example 3, which contained glucomannan in an amount of less than 0.5% by weight relative to the total weight of the composition, was unable to produce noodles and was unable to provide good make-up removal capabilities.
