Description

Technical Field

[0001] This invention relates to a carbonated foaming composition and a cleaning agent composition. Background Technology

[0002] In recent years, foam-type shampoos, facial cleansers, and bath soaps have gained attention from the perspective of ease of use.

[0003] Among them, there is a report on a foaming cosmetic composition that utilizes the property of a mixture of carbonates and organic acids to generate carbon dioxide by adding a small amount of water, producing microbubbles of carbon dioxide (Japanese Patent Application Publication No. 1-290615: Patent Document 1). This foaming cosmetic composition is disclosed as usable as a facial soap, shaving foam, shampoo, or bath soap. However, the foaming cosmetic composition described in Patent Document 1 has the following problem: even a trace amount of water in the mixture of carbonates and organic acids will generate carbon dioxide during storage, and water will be produced as a byproduct of the reaction, causing a chain reaction that results in the packaging material swelling or reduced foaming properties during use.

[0004] To address this issue, the report mentions technologies that improve storage stability. For example, Japanese Patent Application Publication No. 2009-62319 (Patent Document 2) discloses a foaming granule containing an oily component, with a particle size of 150 μm to 1500 μm, thereby improving storage stability.

[0005] In addition, Japanese Patent Application Publication No. 2009-155213 (Patent Document 3) discloses a bathing agent composition that has good storage stability by containing the following components (A) to (C): (A) 25 to 55% by mass of an alkali metal carbonate with a particle size of 180 μm or more, (B) 40 to 70% by mass of an organic acid with a particle size of 180 μm or more, and (C) 0.01 to 10% by mass of a water-insoluble metal oxide.

Detailed Implementation

[0024] The technology described in Japanese Patent Application Publication No. 2009-62319 (Patent Document 2) uses a compression granulation method, which reduces the immediate solubility of the particles. Therefore, it is determined that when this technology is used on carbonated foaming compositions used for lathering shampoos by hand, undissolved components cause a rough feel, resulting in a deteriorated hand feel and thus impairing the user experience. Furthermore, Japanese Patent Application Publication No. 2009-155213 (Patent Document 3) relates to a technology for bath products. If the bath product composition dissolves on the surface of bath water, carbon dioxide cannot fully dissolve in the bath water and escapes. Therefore, in order for the bath product composition to dissolve in bath water, it must precipitate in the bath water and remain in the bath water for a certain period of time. Here, it is a prerequisite to use raw material particles with a certain particle size as the particles constituting the bath product composition. In contrast, carbonated foaming compositions used for lathering by hand require immediate solubility in a small amount of liquid. Therefore, when using larger particles as carbonated foaming compositions, the solubility is poor, resulting in the same roughness problem as above. Carbonated foaming compositions differ from bath products because they are intended for use on hair or the body and come into direct contact with the skin, thus requiring a delicate skin feel.

[0025] Therefore, the present invention relates to a carbonated foaming composition and a cleaning composition that have high storage stability, suppress roughness in the hand, and provide a good user experience.

[0026] The inventors conducted research and discovered a carbonated foaming composition that can solve the above-mentioned technical problems. The carbonated foaming composition contains carbonate and organic acid, wherein the carbonate and organic acid are contained in the form of independent particles (A) (hereinafter also referred to as "particle (A)") containing carbonate and particles (B) (hereinafter also referred to as "particle (B)") containing organic acid, respectively. The median particle size of the carbonate particles (a) (hereinafter also referred to as "carbonate particles (a)") and the organic acid particles (b) (hereinafter also referred to as "organic acid particles (b)"), which are the respective raw materials, is less than or equal to a specified value. The median particle size of at least one of the particles (A) and the particles (B) is greater than or equal to the specified value. The median particle size of particles (A) and particles (B) is greater than or equal to the median particle size of each raw material particle.

[0027] Furthermore, the inventors conducted research and discovered a cleaning agent composition that can solve the above-mentioned technical problems. This cleaning agent composition contains carbonate, organic acid, and surfactant, and contains carbonate and organic acid in the form of independent particles, namely, carbonate particles (A) (hereinafter also referred to as "particles (A)") and organic acid particles (B) (hereinafter also referred to as "particles (B)").

[0042] According to the present invention, a carbonated foaming composition and a cleaning composition with high preservation stability, suppressed roughness and a pleasant feel can be provided.

[0043] [First Embodiment: Carbonated Foaming Composition]

[0044] The carbonated foaming composition of the first embodiment of the present invention contains carbonates and organic acids, wherein,

[0045] The above-mentioned carbonated foaming composition contains particles (A) comprising the above-mentioned carbonate and particles (B) comprising the above-mentioned organic acid.

[0046] The particles (A) mentioned above do not contain organic acids, and the particles (B) mentioned above do not contain carbonates.

[0047] The median particle size of the carbonate particles (a) used as raw materials for the aforementioned particles (A) is 170 μm or less, and the median particle size of the organic acid particles (b) used as raw materials for the aforementioned particles (B) is 500 μm or less.

[0048] The median particle size of at least one of the particles (A) and (B) is 80 μm or larger.

[0049] The median particle size of the above-mentioned particle (A) is greater than or equal to the median particle size of the above-mentioned carbonate particle (a), and the median particle size of the above-mentioned particle (B) is greater than or equal to the median particle size of the above-mentioned organic acid particle (b).

[0050] The carbonated foaming composition of the first embodiment of the present invention is in powder or granule form, for example, a composition used to formulate a foam-like dosage form of a composition containing surfactants, such as shampoo or conditioner. Therefore, the carbonated foaming composition of the first embodiment of the present invention is combined with a surfactant-containing composition and applied to the human body surface including skin or hair. Therefore, a good user experience without a rough feel when foaming is required, and immediate dissolution within a short time is also needed; thus, a small particle size of the particles constituting the carbonated foaming composition is desirable. However, it is known that if the particle size of the carbonated foaming composition is small, even the addition of a hygroscopic agent is insufficient, failing to suppress the generation of carbon dioxide in the packaging material, resulting in poor storage stability. Furthermore, through repeated research, it was found that to suppress the generation of carbon dioxide during storage, the particle size of the carbonate or organic acid needs to be increased to a specific value or higher. To resolve this contradictory requirement, the inventors conducted specific research and found that by setting the diameter of the raw material particles and the diameter of the particles constituting the manufactured carbonated foaming composition to specific ranges, both immediate solubility and storage stability can be achieved. That is, in the carbonate foaming composition according to the first embodiment of the present invention, the median particle size of the carbonate particles (a) and the organic acid particles (b) is less than a predetermined value, and the median particle size of at least one of the carbonate particles (A) and the organic acid particles (B) is greater than a predetermined value, wherein the median particle size of the particle (A) is greater than or equal to the median particle size of the carbonate particles (a) used as raw materials, and the median particle size of the particle (B) is greater than or equal to the median particle size of the organic acid particles (b) used as raw materials, thereby improving storage stability and suppressing roughness during use, resulting in a good user experience.

[0051] Furthermore, by containing carbonates and organic acids in the form of separate particles (A) containing carbonates and (B) containing organic acids, the storage stability and foaming properties can be further improved.

[0052] The carbonated foaming composition of the first embodiment of the present invention may also contain a surfactant within a range that does not inhibit the effectiveness of the surfactant-containing composition used in combination. The surfactant content may be less than 10% by mass, or less than 7% by mass, or less than 5% by mass, or more than 1% by mass, or more than 2% by mass, or more than 3% by mass.

[0111] Furthermore, from the viewpoint of improving storage stability and enhancing user experience, it is preferable that either the carbonate-containing particles (A) or the organic acid-containing particles (B) are granulated separately. From a production perspective, it is preferable that only one of the particles (A) or particles (B) is a granulated particle, while the other is a raw material particle. From a manufacturing efficiency perspective, it is preferable that the organic acid-containing particles (B) are granulated particles, while the carbonate-containing particles (A) are made by directly using carbonate particles (a) as raw material particles.

[0112] Furthermore, from the viewpoint of suppressing the amount of micronized powder, particles (A) and (B) are preferably granulated with at least one of the particles (A) and (B) and a component other than carbonate particles (a) and organic acid particles (b), such as one or more selected from excipients, water-soluble polymers (binders, feel modifiers), and hygroscopic agents.

[0115] <Granulation Method>

[0116] As a granulation method for particles (A) or particles (B), any one of fluidized bed granulation, stirred granulation, rotary granulation, or extrusion granulation can be used. Among the above, from the viewpoint of improving the solubility of the carbonated foaming composition in liquid (water), fluidized bed granulation is preferred.

[0117] Specifically, for example, when granulating particles (A), granulation can be carried out by adding raw materials other than organic acids to a fluidized bed granulator and adding a binder solution made by dissolving the binder in water, ethanol, or a mixture thereof to the uniformly mixed powder. Similarly, when granulating particles (B), granulation can be carried out by adding raw materials other than carbonates to a fluidized bed granulator and adding a binder solution made by dissolving the binder in water, ethanol, or a mixture thereof to the uniformly mixed powder.

[0121] <Method for manufacturing carbonated foaming composition>

[0122] The method for manufacturing the carbonated foaming composition according to the first embodiment of the present invention includes the following steps: using carbonate particles (a) with a median particle size of 170 μm or less and organic acid particles (b) with a median particle size of 500 μm or less as raw materials, granulating at least one of the carbonate particles (a) and organic acid particles (b) to produce granulated particles with a median particle size of 80 μm or more (hereinafter also referred to as the "granulation particle manufacturing step").

[0123] Using carbonate particles (a) with a median particle size of less than 170 μm and organic acid particles (b) with a median particle size of less than 500 μm as raw material particles, at least one of them is granulated to a size of 80 μm or more, thereby producing a carbonated foaming composition that improves storage stability, has excellent solubility, suppresses roughness in the hand, and provides a good user experience.

[0124] The granulation process can be carried out using the granulation method described above.

[0125] Granulation of at least one of the carbonate particles (a) and organic acid particles (b) includes granulating both carbonate particles (a) and organic acid particles (b) separately, or granulating only one of the carbonate particles (a) and organic acid particles (b). Specifically, the raw material particles can be used directly without granulation of either carbonate particles (a) or organic acid particles (b), or the carbonate particles (a) and organic acid particles (b) can be granulated separately to produce carbonate granules (A) and organic acid granules (B) for use. From the viewpoint of further improving storage stability and improving immediate solubility, it is preferable to granulate both carbonate particles (a) and organic acid particles (b) separately. From the viewpoint of improving productivity, it is preferable to granulate only either carbonate particles (a) or organic acid particles (b).

[0126] After the granulation process, if carbonate particles (a) and organic acid particles (b) are granulated separately, the granulated particles (particles (A) and particles (B)) are then mixed with each other using a known mechanism, thereby producing a carbonated foaming composition; or if only one of the carbonate particles (a) and organic acid particles (b) is granulated, the granulated particles are mixed with ungranulated particles using a known mechanism, thereby producing a carbonated foaming composition.

[0127] <Instructions for use of the carbonated foaming composition>

[0128] The carbonated foaming composition of the first embodiment of the present invention is used to contact a composition containing a surfactant to form a foam-like dosage form of the surfactant-containing composition.

[0129] More specifically, the carbonated foaming composition of the first embodiment of the present invention comes into contact with a composition containing a surfactant during use, thereby utilizing the liquid component (water) contained in the composition containing the surfactant, or the liquid component (water) added as needed, to react the carbonate contained in the carbonated foaming composition with an organic acid to generate carbon dioxide, thereby making the composition containing the surfactant into a foam-like dosage form.

[0130] Regarding the carbonated foaming composition of the first embodiment of the present invention, since it naturally begins to foam upon reaction with water, the foaming of the composition containing the surfactant is also faster, and no special foaming operation that requires time or labor is required, so it can be used easily.

[0131] Furthermore, the method of using the carbonated foaming composition of the first embodiment of the present invention is also a foaming method and a cleaning method.

[0132] That is, it is also a foaming method of a surfactant composition in which the carbonated foaming composition of the first embodiment of the present invention is brought into contact with a composition containing a surfactant to form a foam-like dosage form.

[0133] In addition, there is also a body cleaning method in which the carbonated foaming composition of the first embodiment of the present invention is brought into contact with a composition containing a surfactant to form a foam-like dosage form, and the foam-like surfactant composition is applied to the surface of the human body to clean the body.

[0134] In addition, there is a hair cleaning method in which the carbonated foaming composition of the first embodiment of the present invention is brought into contact with a composition containing a surfactant to form a foam-like dosage form, and the foam-like surfactant composition is applied to hair to clean it.

[0135] In this specification, the term "composition containing surfactants" is not particularly limited as long as it is a surfactant-containing composition applied to the surface of the human body, including skin and hair. Examples include: hair cosmetics, facial cleansers, body washes (shower gels), etc. Examples of hair cosmetics include: shampoos, conditioners, hair treatments, hair masks, styling agents, hair dyes, hair growth products, etc.

[0136] From the viewpoint that the effects of the present invention can be more effectively achieved, the composition containing surfactant is preferably a hair cosmetic, more preferably one selected from shampoo, conditioner, conditioning agent and hair mask, and even more preferably a shampoo.

[0137] Furthermore, from the viewpoint that the effects of the present invention can be more effectively achieved, the composition containing the surfactant is preferably in liquid form.

[0138] When hair cosmetics are applied directly to hair, friction occurs between the hair and scalp during foaming or when blending with the hair, causing strain on the hair or scalp. However, by using the carbonated foaming composition of the first embodiment of the present invention, a foam-like hair cosmetic can be prepared for application, thus reducing the strain on the hair or scalp. Furthermore, the carbonated foaming composition of the first embodiment of the present invention has excellent immediate solubility, resulting in excellent user experience, such as skin feel, even when dissolved in hair cosmetics. Moreover, the carbonated foaming composition of the first embodiment of the present invention can be used in combination with commercially available shampoos or conditioners, and no special containers or tools are required for foaming, thus offering excellent versatility. Especially when packaged in single-use quantities, it is easy to carry and can be used at any destination. Additionally, the blood circulation-promoting effect from carbon dioxide is also expected.

[0139] More specifically, as a method of using the carbonated foaming composition according to the first embodiment of the present invention, for example, the carbonated foaming composition is placed in the palm of the hand, a composition containing a surfactant is added to the carbonated foaming composition, and the surfactant-containing composition is fully incorporated into the carbonated foaming composition on the palm. After natural foaming, it gently foams and is then applied to the face, hair, body, etc., of the intended recipient. Furthermore, the order in which the composition is placed in the palm is not limited; it is also possible to place the surfactant-containing composition in the palm first and then add the carbonated foaming composition to the surfactant-containing composition. However, from the viewpoint of reducing the dispersion of the carbonated foaming composition and making the surfactant-containing composition foam more effectively, it is preferable to place the carbonated foaming composition in the palm first and then add the surfactant-containing composition.

[0140] Furthermore, in cases where foaming of the surfactant-containing composition is difficult, water may be added as needed. The timing of water addition is not particularly limited; for example, the surfactant-containing composition may be added after the carbonated foaming composition has come into contact with water, or the carbonated foaming composition may be added after the surfactant-containing composition has come into contact with water. Alternatively, water may be added after the carbonated foaming composition has come into contact with the surfactant-containing composition. From the viewpoint of making the surfactant-containing composition foam more effectively, it is preferable to add the surfactant composition after the carbonated foaming composition has come into contact with water. From the viewpoint of improving user experience, it is preferable to use the product without adding water.

[0141] When the composition containing the surfactant is in liquid form, regarding the amount of the liquid surfactant-containing composition added to the carbonated foaming composition, from the viewpoint of improving the solubility and foaming properties of the carbonated foaming composition, the mass ratio of the carbonated foaming composition to the added surfactant-containing composition (carbonated foaming composition / surfactant-containing composition) is preferably 1 / 30 or more, more preferably 1 / 25 or more, even more preferably 1 / 20 or more, and preferably 1 / 0.5 or less, more preferably 1 / 1 or less, and even more preferably 1 / 2 or less. Furthermore, the mass ratio (carbonated foaming composition / surfactant-containing composition) is preferably 1 / 30 or more and 1 / 0.5 or less, more preferably 1 / 25 or more and 1 / 1 or less, and even more preferably 1 / 20 or more and 1 / 2 or less.

[0142] Furthermore, from the viewpoint of solubility and foaming properties, the amount of water to be added relative to 1 g of the carbonated foaming composition is preferably 0.1 g or more and 20 g or less, more preferably 0.5 g or more and 15 g or less, and even more preferably 1 g or more and 10 g or less.

[0143] The temperature of the water added to the carbonated foaming composition is not particularly limited, but is preferably 15°C to 50°C, more preferably 15°C to 45°C, and even more preferably 20°C to 45°C.

[0144] When the composition containing surfactant is in liquid form, from the viewpoint of foam retention, the carbonated foaming composition of the first embodiment of the present invention, after contacting the liquid composition containing surfactant (in the case where the carbonated foaming composition is first contacted with water, that is, after contacting the carbonated foaming composition with water), is preferably applied to the hair and other objects within 5 minutes, more preferably within 3 minutes, further preferably within 2 minutes, and even more preferably within 1 minute and 30 seconds.

[0145] The carbonated foaming composition of the first embodiment of the present invention can preferably be used as a foaming aid that helps to foam compositions containing surfactants, especially hair cosmetics such as shampoos or conditioners.

[0146] The carbonated foaming composition of the first embodiment of the present invention can be provided by being sealed in packaging material. Even when stored in packaging material, the carbonated foaming composition of the first embodiment of the present invention is not prone to expansion of the packaging material due to carbon dioxide generation, thus exhibiting excellent storage stability in the product form sealed in packaging material.

[0147] There are no particular limitations on the shape of the packaging material, as long as it has a structure that can seal in the carbonated foam composition; examples include bags and bottles. Among these, bag-shaped packaging materials are preferred.

[0148] There are no particular restrictions on the materials used to make the packaging materials, as long as they are materials that can be sealed with a carbonated foam composition. For example, in the case of bag-shaped packaging materials, resin films or laminated films made of inorganic films composed of metals or metal oxides can be used.

[0149] <Hair care cosmetics set>

[0150] The hair cosmetic kit of the first embodiment of the present invention comprises a carbonated foaming composition and a composition containing a surfactant.

[0151] The carbonated foaming composition and the surfactant-containing composition used in the hair cosmetic kit of the first embodiment of the present invention use the same substances as those described above. When using the hair cosmetic kit, the carbonated foaming composition is brought into contact with the surfactant-containing composition, and the surfactant-containing composition is formulated into a foam-like dosage form for use.

[0152] [Second Embodiment: Cleaning Composition]

[0153] The cleaning composition of the second embodiment of the present invention is a cleaning composition containing carbonate, organic acid and surfactant, wherein,

[0154] The cleaning agent composition described above contains particles (A) comprising the aforementioned carbonate and particles (B) comprising the aforementioned organic acid.

[0155] The particles (A) mentioned above do not contain organic acids, and the particles (B) mentioned above do not contain carbonates.

[0156] The median particle size of the carbonate particles (a) used as raw materials for the aforementioned particles (A) and the median particle size of the organic acid particles (b) used as raw materials for the aforementioned particles (B) are both 170 μm or less.

[0157] The median particle size of at least one of the particles (A) and (B) is 80 μm or larger.

[0158] The median particle size of the above-mentioned particle (A) is greater than or equal to the median particle size of the above-mentioned carbonate particle (a), and the median particle size of the above-mentioned particle (B) is greater than or equal to the median particle size of the above-mentioned organic acid particle (b).

[0159] In addition to the cleaning effect of surfactants, the cleaning composition of the second embodiment of the present invention also exhibits excellent cleaning properties by reacting carbonates with organic acids to produce carbon dioxide when the cleaning composition is dissolved in water.

[0160] Furthermore, the cleaning agent composition of the second embodiment of the present invention is in powder or granular form and is mainly used for cleaning the face or body. Such a cleaning agent composition applied to the skin, such as the face or body, is required to have a pleasant feel when foaming without any roughness, and needs to dissolve quickly; therefore, it is desirable that the particle size of the particles constituting the cleaning agent composition is small. However, it is known that if the particle size of the cleaning agent composition is small, even the addition of a humectant is insufficient, and the generation of carbon dioxide in the packaging material cannot be suppressed, resulting in poor storage stability. Furthermore, through repeated research, it was found that in order to suppress the generation of carbon dioxide during storage, the particle size of the carbonate or organic acid needs to be increased to a certain value or higher. To resolve this contradictory requirement, the inventors conducted specific research and found that by setting the diameter of the raw material particles and the diameter of the particles constituting the manufactured cleaning agent composition to specific ranges, both immediate solubility and storage stability can be achieved. That is, in the cleaning composition according to the second embodiment of the present invention, the median particle size of the carbonate particles (a) and the organic acid particles (b) is less than a specified value, and the median particle size of at least one of the carbonate particles (A) and the organic acid particles (B) is greater than or equal to a specified value.

[0220] Using carbonate particles (a) and organic acid particles (b) with a median particle size of less than 170 μm as raw material particles, at least one of them is granulated to a size of 80 μm or more, thereby producing a cleaning agent composition that improves storage stability, has excellent solubility, suppresses roughness on the hand, and provides a good user experience.

[0221] The granulation process can be carried out using the granulation method described above.

[0222] The term "granulation of at least one of carbonate particles (a) and organic acid particles (b)" includes granulation of both carbonate particles (a) and organic acid particles (b) separately, or granulation of only one of carbonate particles (a) and organic acid particles (b).

Alternatively, if only one of carbonate particles (a) and organic acid particles (b) is granulated, the granulated particles are mixed with ungranulated particles using a known mechanism to produce a cleaning agent composition.

Even when stored encapsulated in packaging material, the cleaning composition of the present invention is not prone to expansion of the packaging material due to carbon dioxide generation, thus exhibiting excellent storage stability in its encapsulated form.

[0233] There are no particular limitations on the shape of the packaging material, as long as it has a structure that allows the detergent composition to be sealed inside; examples include bags and bottles. Among these, bag-shaped packaging materials are preferred.

[0234] There are no particular restrictions on the materials used to make the packaging materials, as long as they can be used to seal in a cleaning agent composition.
