Description

  TECHNICAL FIELD The present invention relates to a detergent composition such as a body soap and a face wash soap mainly composed of salt particles, and a paste containing a docami aloe extract that is preferably used for the detergent composition.

  As shown in Non-Patent Document 1, by putting a lot of salt directly on acne scars and in the body and massaging so that it gets wet into the skin, excess sebum is pushed out, skin dullness and darkening are removed, In recent years, salting beauty has attracted attention due to the introduction of the user's impression that there is a slimming effect due to skin tightening.

  However, imprinting salt directly on the skin is not easy to use. While rubbing, salt particles fall apart from the skin surface. In addition, rubbing directly with salt may cause roughness and damage to the skin, and it may be worse depending on the method of use. .

  Non-Patent Document 1 introduces not only a method of using salt as it is but also a method in which salt particles are dispersed in squalane oil, honey, egg white or the like. These are made by using squalane oil or the like as a dispersion medium for salt particle aggregates, making it creamy and easy to imprint on the skin, but it has a high element as a massage cream and feels refreshed after washing with water. However, it is inferior compared to when salt particles are used directly, and sebaceous skin has a slimy feeling after use. For this reason, after massage, it is necessary to clean and wash the body with soap separately, and it is difficult to obtain the refreshing feeling and the smooth feeling of the skin that are originally obtained by the salting effect.

  Under such circumstances, there is a demand for a cleaning agent containing salt granules so that a refreshing feeling can be obtained after use, not as an oily massage cream.

  In general, liquid soap contains water or contains a humectant, so it is not easy to contain a water-soluble salt in a salt state.

  As a detergent composition in which sodium chloride is stably incorporated in the detergent in a crystalline state and without any change in state, Patent Document 1 (Japanese Patent Laid-Open No. 9-272894) discloses 10% or more surfactant (mainly carboxylic acid type surfactant). Agent) A salt-containing detergent composition containing 1% or more of salt crystals and a polyhydric alcohol and substantially free of water is disclosed. By using a substantially non-aqueous surfactant for the soap base, water-soluble salt crystals are stably dispersed.

  Patent Document 2 (Patent No. 31655892) discloses a method for dispersing salt particles stably in a detergent composition containing fatty acid salt as a main component in a solution containing fatty acid salt such as salt. The salt of the fatty acid salt is salted out while dissolving the particles of the water-soluble compound, and after obtaining the particles in which the fatty acid salt deposited by the salting-out is adhered to the surface of the water-soluble compound, it is added to the cleaning composition. , A method of dispersing this substantially uniformly, and a detergent composition produced by the method, that is, a detergent composition in which particles of a water-soluble compound having a fatty acid salt attached to the surface thereof are dispersed substantially uniformly. It is disclosed.

  Furthermore, Patent Document 3 (Japanese Patent Laid-Open No. 2000-109894) discloses a cleaning composition containing a fatty acid salt as a main component, water-soluble compound particles such as salt attached with a fatty acid salt deposited by salting-out, and chloride. A composition in which particles such as aluminum are uniformly dispersed in a cleaning agent is disclosed. In this composition, when the detergent composition is used in water, the fatty acid salt first dissolves in water to form a fatty acid salt solution, and in the fatty acid salt solution, the particulate water-soluble compound dissolves. Since it exhibits resistance, the water-soluble compound can be maintained in a granular state for a long time, and a massage effect by the particles can be obtained.

  Patent Document 4 (Japanese Patent Application Laid-Open No. 2002-105488) discloses a detergent composition containing an ionic surfactant, an undissolved sodium chloride granule, urea, and water. .

  In Patent Document 5 (Japanese Patent Laid-Open No. 2002-285199), a natural product powder is added to a detergent containing a surfactant after dissolving a water-soluble compound at a concentration higher than that capable of salting out the surfactant. A cleaning composition in which the entire surface of the natural product powder is coated with the surfactant that is salted out has been proposed. Here, sodium chloride (sodium chloride) is contained as a water-soluble compound that dissolves in a detergent medium for salting out the surfactant. As natural product powders, fine powders of herbs such as aloe leaves are used.

  However, commercially available salt-containing detergent compositions contain salt particles only as an additive, or even if they are contained in large amounts, the salt particles dissolve immediately and are sufficient. The scrubbing effect cannot be obtained, or conversely, the salt particles exist stably, but the rough feeling is strong and unsuitable for face washing, so the original effect of salting is fully demonstrated The reality is not to say. There is also a need to improve the balance between the refreshing feeling and the moist feeling after washing.

  In addition, a soap having an anti-bacterial effect on allergic sensitive skin is desired, and a soap containing dokudami extract is proposed in Patent Document 6 as satisfying such a requirement.

Shufunotomo Co., Ltd., published October 10, 1994, magazine 61398-94 JP-A-9-272894 Japanese Patent No. 3165893 JP 2000-109894 A JP 2002-105488 A JP 2002-285199 A JP-A-5-186797

  The present invention has been made in view of such circumstances, and the object of the present invention is easy to use, and after washing, a refreshing feeling is obtained and a moist feeling that is the original salting effect is obtained. Another object is to provide a cleaning composition that can achieve a massage effect.

  The skin cleanser composition of the present invention contains 70 to 90% by mass of salt particles, 5 to 15% by mass of aloe juice, and 4 to 15% by mass of surfactant, and preferably 0.05 to 1 of dokudami. .5% by mass is contained.

  It is preferable that the aloe juice is obtained by removing solids from the juice of the crushed aloe mesophyll. Moreover, it is preferable that the said dokudami is what extracted dokudami leaf with the aloe juice, or what dispersed the dokudami leaf ground material in the aloe juice.

  The surfactant is preferably mainly composed of an anionic surfactant, and the salt particles are preferably 97% or more of sodium chloride and an average particle size of 100 to 500 μm.

  The facial cleansing composition of the present invention contains 70 to 90% by mass of salt granules having an average particle size of 100 to 300 μm, 5 to 15% by mass of aloe juice, 4 to 15% by mass of surfactant, and It is preferable to contain 05-1.5 mass%.

  The skin cleanser composition and face cleanser composition of the present invention preferably have fluidity to such an extent that they can be mixed and stirred by hand.

  The paste containing dokudami and aloe extract of the present invention is a paste containing aloe juice and ground dough leaves in a mass ratio (aloe soup: ground dough leaves) in a ratio of 1: 0.5 to 1: 1.5. It is a shape.

  In the present invention, the salt particles are used as a dispersion medium, and the salt particles are stably contained in the cleaning agent because the salt particles are used as a dispersion medium to the extent that the salt particles are not separated. It exists and can exert a massage effect while suppressing the feeling of saltiness on the skin. Therefore, the original salting effect can be easily achieved, and the antibacterial, anti-flame and anti-drug effects of aloe and dokudami can be exhibited. Furthermore, since the aloe juice and dokudami extract easily penetrate into the skin from the pores opened by salting, the effects of aloe and dokudami can be exhibited effectively.

  The cleaning composition of the present invention is a crude cleaning product containing salt particles at a high content of 70 to 90% by mass, and contains aloe juice, a surfactant, and, if necessary, a dokudami extract. is there.

  As the salt particles, high-purity purified salt, commercially available salt, rock salt mainly composed of sodium chloride, sun salt, dried mineral spring water, and the like can be used. A natural salt having a sodium chloride content of 97% or more is preferably used rather than almost pure sodium chloride crystals. This is because natural salt contains a lot of minerals.

  As the salt particles, those having a particle size of 0.01 mm to 1 mm and an average particle size of 0.1 mm to 0.5 mm (100 to 500 μm) are preferably used. If it is less than 0.01 mm, it dissolves immediately on the skin wet with water or hot water, and a sufficient massage effect cannot be obtained. On the other hand, if it exceeds 1 mm, there is a sense of incongruity during use, and sometimes the skin is damaged. Particularly for facial cleansing, those having an average particle size of 0.1 to 0.3 mm (100 to 300 μm) and substantially not exceeding 0.5 mm are preferably used. A cleaning composition mainly composed of salt grains in such a particle size range is mousse and is gentle to the skin even though it contains a large amount of salt grains. This is because it is less suitable.

  Such salt granules are contained in the cleaning composition in an amount of 70 to 90% by mass. This is because in order to exhibit the original salt coating effect, it is necessary to contain a large amount of salt as a main component.

  The aloe juice used in the present invention is obtained by removing solid residue from the grated juice of almond vera or aloe vera leaf flesh or squeezed juice of crushed material, for example, by finely cutting the aloe leaf meat and applying it to a juicer, Or after applying to a mixer, it filters by cotton cloth etc. and is obtained by removing a solid residue. Such aloe juice contains aloin, aloe emodin, aloein, aloesin, aloeson, beta bavaloin, aloe mannan, saponin, mucopolysaccharide complex, limonene, glucosamine, hexuronic acid, uronic acid and the like. In particular, the water contained in the aloe juice is biological water in the cells of aloe, and since normal water and clusters such as ion exchange water, purified water, and distilled water are not large, it is difficult to dissolve sodium chloride. Moreover, since it is in a state of being bound or adsorbed to polysaccharides and glycoproteins in such a state of biologically active water, it is considered that the oil and water partition ratio is good and the transdermal absorbability is good. This is considered to be excellent in hydration and penetration of active ingredients into the skin.

  Aloe juice is contained in the cleaning agent in an amount of 5 to 15% by mass. In order to sufficiently obtain the aloe effect, about 5% is necessary, and when it exceeds 15%, salt particles existing at a saturation concentration or more are precipitated and the liquid phase and the solid phase are separated.

The surfactant is contained in the cleaning agent in an amount of 4 to 15% by mass. If it is less than 4%, the easiness of the cleaning agent becomes insufficient, and the effect of removing dirt as a cleaning agent becomes insufficient. Meanwhile, 1
This is because even if the content exceeds 5%, the content of the salt particles is relatively reduced, and it is difficult to obtain the original salt coating effect.

  The surfactant used in the present invention may be any surfactant generally used for skin cleaning. Specifically, a neat soap dried product obtained by adding sodium hydroxide and / or potassium hydroxide to a saponified product of natural fats and oils generally used for soap ingredients, and esters of higher alcohols derived from fats and oils. Compounds, sulfates, etc., and higher amine betaines, oxides, ethylene oxide, and the like can be used.

  Natural fats and oils used as raw materials include apricot kernel oil, avocado oil, olive oil, extra virgin, beef tallow, cucumber oil, walnut oil, grape seed oil, corn oil, cocoa butter, coconut oil, sesame oil, wheat germ oil, rice bran oil, Shea butter, sweet amor oil, shortening, soybean oil, evening primrose oil, camellia oil, rapeseed oil, palm oil, palm kernel oil, horse oil, peanut oil, castor oil, sunflower oil, hazelnut oil, safflower oil, hemp oil, jojoba oil , Macadamia nut oil, mango butter, beeswax, cottonseed oil, lard, lanolin, and rosehip seed oil.

  The surfactant used in the present invention is not limited to the fatty acid salt derived from the above natural fats and oils, but is derived from petroleum raw materials (higher alcohols, alkylbenzenes, α-olefins, alkylphenols), and amino acid surfactants. May be. In short, it is only necessary to use a surfactant that has an appropriate detergency and does not have excessive degreasing action for use in skin cleaning. Anionic surfactants, nonionic surfactants, and amphoteric surfactants are appropriately selected. Can be used in combination, and a combination mainly composed of an anionic surfactant is preferred.

  Examples of the anionic surfactant used in the present invention include higher fatty acid salt (soap), polyoxyethylene alkyl ether sulfate, alkylbenzenesulfonic acid alkyl sulfate ester salt, α-sulfo fatty acid ester salt, alkylphenyl polypeptide oxyethylene ether. , Alkyl sulfate salts, alkyl ether sulfates, lauroyl sarcosine salts, POE alkyl ether carboxylates, α-olefin sulfonates, higher fatty acid amide sulfonates, higher fatty acid ester sulfonic acids, dialkyl sulfosuccinates, alkyl allyl sulfones Acid salt, higher alcohol / sulfuric acid ester salt, POE alkyl ether sulfuric acid ester salt, polyoxyethylenesulfosuccinic acid monoester salt, N-acylmethyltaurine salt, glycerin fatty acid ester sulfuric acid Examples include ester amino acids, higher fatty acid alkylolamide sulfates, monoalkyl phosphates, acyl glutamates, acyl sarcosyl salts, acyl-β-alanine salts and the like, collagen hydrolyzate acyl compounds, and the like. Any of these may be used alkali metal salts such as sodium and potassium, organic amine salts such as triethanolamine, and alkaline amino acid salts such as L-lysine.

  Examples of amphoteric surfactants include dimethylalkylamine oxide, N-alkyl betaine, alkyl acetate betaine, imidazolinium betaine, amino betaine, carbobetaine, and amide acetate betaine.

  Nonionic surfactants include fatty acid diethanolamides, alkyl polyglucosides, fatty acid alkanolamides, polyoxyethylene alkyl ethers, alkyldimethylaminooxides, alkyl glycosides, polyoxyethylene-polypeptideoxypropylene block copolymers, and the like. .

  If desired, the cleaning composition of the present invention may contain 0.05 to 1.5% by weight of dokudami. It is possible to obtain the effect of suppressing itchiness due to docudami and the effect of skin troubles such as stains, acne and dullness due to antibacterial and vascular enhancement effects.

  The dokudami used in the present invention may be mixed with a commercially available dokudami powder or dokudami extract solution, or may be mixed directly with a pulverized product of dokudami leaf, but preferably the dokudami extract is extracted. Aloe juice containing dokudami extract performed using aloe juice or paste-like dokudami aloe extract (hereinafter referred to as “paste containing dokudami aloe extract”) obtained by uniformly dispersing and dissolving ground dough leaves in aloe juice. .

  In general, as for the Dokudami extract, a Dokudami extract-containing aqueous solution or alcohol obtained by extracting Dokudami leaves with hot water or alcohol, or a powder obtained by distilling and drying these, a granulated Dokudami powder, or a dried Dokudami leaf obtained finely. The dokudami powder is generally used. However, if the detergent composition contains 0.05% by weight or more of wolfram extract using an aqueous solution or alcohol containing the wolfberry extract, the amount of water or alcohol increases and the salt particles are dissolved. . On the other hand, dokudami powder has no effect on salt particles, but it is difficult to uniformly mix dokudami powder of about 0.05% by weight with salt particles. From such an amount, it is impossible to realize the effect of suppressing itchiness by the Dokudami extract, as well as antibacterial and blood vessel enhancing effects. In this respect, the aloe juice containing docami extract or the paste containing docami aloe extract used in the present invention has almost no effect on the salt particles and can easily be achieved up to 1.5 mass% of the dokudami content. Moreover, since the pulverized dokudami leaf is a paste or liquid stably dispersed in the aloe juice, it can be uniformly mixed and dispersed throughout the cleaning agent. Therefore, even if it is the amount used by the user every day, it is possible to use a cleaning agent containing a trace amount of the dokudami extract and to realize the effect of the dokudami.

  The method for producing aloe juice containing docami extract is not particularly limited. Specifically, it can be produced by steaming the leaves, finely cutting the leaves, applying them to aloe juice and a mixer, and then removing the dokudami fibers by filtration. . Aloe juice, unlike mere water and alcohol, has low solubility in salt granules, and since some of the aloe extract originally contained as aloe extract is used as a dispersion medium for dokudami extract, it maintains the state of salt granules As it is, a cleaning composition having a desired component composition can be provided.

  The dokudami aloe extract-containing paste is mixed with aloe juice while finely cut dokudami leaves are added to the aloe juice and the dokudami leaves are pulverized with a mixer. At this time, it is filtered with a filter cloth, etc., and the operation of pulverization and dispersion is performed again by adding dokudami leaves to the filtrate, so that, in mass ratio, dokudami: aloe = 0.5: 1 to 1.5: 1, preferably Can obtain a paste containing a high amount of dokudami and aloe extract of 0.8: 1 to 1.3: 1. The dokudami powder obtained by drying the dokudami leaf extract or the dokudami powder obtained by pulverizing the dried dokudami leaf absorbs aloe juice and cannot be stably dispersed in the aloe juice, but is not dried In the case of pulverized dokudami leaves, it can be stably dispersed in the aloe juice. Further, in the case of the paste containing docami-aloe extract, it is applied to the mixer as it is without steaming the docami leaves in advance, so that it is possible to prevent the active ingredients of docami from being decomposed by heat. Furthermore, the aloe juice serving as a dispersion medium for the pulverized dokudami leaf is cooled, preferably cooled to ice or a sherbet, so that the active ingredient of dokudami decomposes even if the temperature is increased by high-speed mixing and stirring. It is possible to prevent such a high temperature.

  Since both the aloe juice containing docami extract and the paste containing docami aloe extract are in a viscous fluid or liquid state, they can be easily and uniformly mixed in the detergent. Thereby, even if it is about the fee of use for 1 time, a docami extract will be contained and the stagnation inhibitory effect and antibacterial effect of docami can be exhibited effectively. In addition, since aloe juice is used as a dispersion medium, a dokudami extract in which the odor of dokudami has disappeared despite the high content of dokudami is obtained, and added to the cleaning composition as it is. There is no odor of Dokudami. Moreover, since water and alcohol are not used as the dokudami dispersion medium, it is possible to contain a high content of 1.5% by weight without affecting the salt particles.

  In addition to the above components, the cleaning composition of the present invention may contain a moisturizer such as a higher alcohol, a metal sequestering agent, sorbitol, a fragrance, a pigment, and the like, if necessary.

  Preservatives may also be included as necessary, but contain a large amount of sodium chloride as a main component and the moisture content is kept low, so that it is free of miscellaneous bacteria despite containing aloe juice. There is almost no breeding or denaturation, and the quality is stable.

  The cleaning composition of this invention contains the said component in the said ratio. After mixing the salt granules with aloe juice, a surfactant may be added and mixed, or the salt granules, surfactant, and aloe juice may all be mixed together, or the salt granules and surfactant. After mixing the agent, it can be produced by an appropriate method such as mixing aloe juice. After mixing, you may leave it for about a month. Thereby, excess water can be evaporated.

  The salt particles may be simply mixed with the surfactant and the aloe juice, but when the already prepared surfactant is not used, the soap oil is heated to a liquid, and sodium hydroxide or potassium hydroxide is used. After cooling the saponified product, add a predetermined amount (saturated concentration or more) of salt granules, salt out glycerin to prepare a soap base, evaporate the water, and then mix the aloe juice May be. Thereby, the cleaning composition in a state where the surface of the salt particles is coated with the surfactant can be easily obtained.

  The cleaning composition having the above-described configuration is mainly an aggregate of salt particles, but a surfactant and aloe juice are used as a dispersion medium.

  Since the salt particles can flow in the form of a solid-liquid sol by coexistence with the surfactant and the aloe soup, it can be stirred by hand, It can be applied smoothly on the skin. In particular, by setting the average particle size of the salt granules to 100 to 300 μm, it can be made into a mousse shape in which air bubbles are involved, and it can be a cleansing composition that is smooth and sensitive to the skin and is suitable for face washing. .

  In addition, since the surfactant exists so as to cover the surface of the salt particles, the surfactant acts as a lubricant between the skin and the salt particles, so that it feels rough when the salt particles are rubbed directly. There is no. And even if the cleaning composition of the present invention is rubbed on moisture-wet skin, it can exist stably as salt particles on the skin longer than mere salt particles. As a result, it is possible to promote a sufficient scrub effect and further discharge of excess sebum and moisture due to salting, and the original effect of salting beauty can be exhibited.

  The skin cleansing composition of the present invention is used by touching it on the skin of the body, face and the like. The salt granule rolls the soap ingredients and the aloe juice on the skin surface, and the salt granule rolls, resulting in a scrub effect, blood circulation promotion effect, removal of old keratin etc., massage effect Is obtained. Moreover, since sodium chloride is water-soluble, if it continues to massage on the skin wet with water or hot water, a granular body will melt | dissolve little by little and it will wash away easily. And during massage, as a natural effect of salt, it stimulates pores and promotes the discharge of moisture and oil in the skin from osmotic pressure, which not only removes dirt from pores, By coming out above, it feels smooth. When washed away with water, it feels refreshing. In addition, since the salt particles stay on the skin surface for a long time and can exert a massage effect, during this time, the aloe juice can stay on the skin surface for a long time as the salt particles roll, and the active ingredients of aloe and dokudami are inside the skin. Can penetrate.

  Therefore, itching of the skin is suppressed, the pores are soiled, and the discharge of excess sebum is promoted. After use, the feeling of being moist and refreshing is balanced. In addition, blood circulation is promoted by the massage effect, and the antibacterial and anti-inflammatory effects of aloe and dokudami extract are useful for preventing acne and eczema, and the skin activation effect by long-term use can be expected.

[Preparation of aloe juice]
Kidachi aloe was applied to a juicer to obtain aloe juice A from which solids had been removed.
Also, cut off the 2cm square of Kidachi Aloe, and with a commercial mixer (9700 times / minute when loaded with 1800ml water), roughen about half of the predetermined amount for 1 minute to make it liquid, and then add the remaining aloe 4 Rotated for a minute to make it a liquid liquid. This aloe liquid was filtered through a cotton cloth to remove solids, and aloe soup B was obtained.

[Preparation of dokudami extract]
(1) Preparation of aloe juice containing dokudami extract After steaming dokudami leaves, 50 g of aloe juice A prepared above and 3 pieces of dokudami leaves (about 2.5 g) were put together in a domestic mixer for 2 minutes, then cotton cloth And filtered to obtain 50 ml of aloe juice containing dokudami extract.

(2) Preparation of dokudami / aloe extract-containing paste Unscratched dokudami leaves were washed and wiped off. The aloe juice B that had been stored frozen was half-thawed, a small amount of dokudami leaf was added thereto, mixed and stirred with a commercial mixer (9700 times / min when loaded with 1800 ml water) for 2 to 3 minutes, and then filtered with a cotton cloth. Add new aloe juice B, residual dokudami leaf residue and fresh dokudami leaf to the obtained filtrate, and mix again for 2 to 3 minutes with a commercial mixer (9700 times / min when loaded with 1800 ml water) After stirring, it was filtered with a cotton cloth. The operation of adding aloe juice B, residual dokudami leaf residue and fresh dokudami leaf to the obtained filtrate, applying again to the mixer, and filtering is performed at a mass ratio of aloe soup juice: dokudami leaf to 1: 1. It was done until. The obtained paste containing dokudami and aloe extract hardly left a solid residue even when filtered with the above cotton cloth. Moreover, even after mixing and stirring a plurality of times by a mixer, it was at room temperature.

(3) Preparation of dokudami powder After 750 g of dokudami leaf was sun-dried, it was pulverized with a mill mixer to obtain 105 g of dokudami powder.
The work was carried out by dividing 19.72 g of dokudami powder (corresponding to 141.5 g in terms of dokudami leaf) into four portions, and adding one portion to 141.5 g of aloe juice B and stirring for 1 minute with a commercial mixer. When a predetermined amount of dokudami powder was added, the mixture could not be stirred with a mixer.

[Example 1]
As the salt particles, “Ako salt” (average particle size 418 μm, sodium chloride content 97.72%, Mohs hardness 2 to 2.2) manufactured by Ako Seawater Co., Ltd. was used.

  50 ml of aloe juice containing docami extract prepared above and 50 g of aloe juice A were mixed with 650 g of salt granules. Due to the moisture content, the aggregates of loose particles became hardened slowly. As a surfactant, 50 cc of a brand name “Libre Aloe” of Futaba Chemical Co., Ltd. was added while slowly stirring.

  Here, "Libre aloe" is a soap component mainly composed of palm coconut oil, potash soap base, cocoamphoacetate Na, cocamidopropyl betaine / lauric acid TEA, distearate glycol, EDTA-2Na, etidronate, propyl Paraben and methyl paraben are included.

  The cleaning agent thus prepared is an aggregate of flowable salt particles that can be scraped by hand, and the salt particles can be separated, but the solid-liquid sol form with a sense of unity as a whole. It was a thing.

[Example 2]
Implemented except that Mongolian lake salt “Living salt” (average particle size 280 μm, sodium chloride content 99.28%, Mohs hardness 2 to 2.2) sold by Salt Kansai Co., Ltd. was used as the salt particles A cleaning composition was prepared in the same manner as in Example 1.
The obtained cleaning composition was mousse-like smooth rather than an aggregate of salt particles. When this was used to slide on wet skin, the salt granules rolled smoothly on the skin and there was no roughness.

Example 3
As the salt particles, “Ako salt” manufactured by Ako Seawater Co., Ltd. (average particle size 418 μm, sodium chloride content 97.72%, Mohs hardness 2 to 2.2) 36.9 kg and Mongolia used in Example 2 A mixture of 24.6 kg of lake salt was used. To this mixed salt granule, 7.75 kg of Futaba Chemical Co., Ltd. trade name “Libre Aloe” as a surfactant was added with slow stirring.

  Next, 3.0 kg of the aloe juice B prepared above was added, and further 1.4 kg of the paste containing the docami aloe extract prepared above (0.7 kg of aloe juice B, 0.7 kg of dokudami) was added and mixed.

  The cleaning agent thus prepared was a composition having an intermediate hardness between Example 1 and Example 2.

[Comparative Example 1]
About 200 ml of ion-exchanged water was added to 200 g of the salt granules used in Example 1, and the mixture was stirred with a stirrer to allow water to blend into the entire salt granules to obtain a cleaning composition.

[Comparative Example 2]
In Comparative Example 1, a detergent composition was prepared using the aloe juice prepared in Example 1 instead of ion-exchanged water.

[Comparative Example 3]
200 g of the salt granules used in Example 1 and 20 ml of “Libre Aloe” used in Example 1 were mixed. It stirred with the stirring bar, the whole salt granule was made to adapt to surfactant, and it was set as the cleaning composition.

[Reference example]
We used a commercially available body soap with aloe salt seaweed (Aura Cosmetics Co., Ltd., “Esthe Body Soap EX550” sold by Alux Co., Ltd.) Squalane oil was used instead of surfactant, and salt was dispersed in this oil It has been made.

〔Evaluation methods〕
The cleaning composition prepared above is applied on the arm and washed with the arm in between, handling ease, feeling of use, salt particle stability, and feeling after use after rinsing with water. Were evaluated according to the following evaluation criteria. The results are summarized in Table 1.

(1) Ease of handling When the detergent composition is scooped up in the hand and spread on the skin surface of the arm, it does not stretch on the skin surface and falls off (×), but not so much that it spills. It is bulky as an aggregate of the body, and the elongation on the skin is poor (△). As a whole, it is a viscous fluid like a conventional body soap and can be easily brought on the skin. Evaluation was made in three stages (○) that can be extended.

(2) Feeling of use When the cleaning agent is extended on the skin and rubbed lightly, if it is rubbed and kept rubbing, the sensitive skin is too irritating (×), there is a grain feeling, but it hurts even when rubbed The evaluation was made in four stages: no feeling (Δ), smooth extension (◯), and smoothness (◎) that hardly felt graininess.

(3) Stability of salt granules The detergent was rubbed lightly on wet skin for about 30 seconds. The granules dissolve in 10 to 20 seconds after dissolution (×), and almost dissolve in about 30 seconds (Δ). The granules are stably present on the skin for 30 seconds and have a scrub effect. It was evaluated in two stages (◯) that could be demonstrated.

(4) Feeling after use After washing and rinsing with water, it is slimy (×), it feels refreshing but the skin does not feel moist and smooth (△), it feels refreshing and moist and smooth The evaluation was made in three grades (○).

〔Evaluation results〕

  As can be seen from Table 1, if a surfactant is not included (Comparative Examples 1 and 2), it is difficult to handle as an aggregate of salt particles. On the other hand, the inclusion of the surfactant and oil makes the aggregate of salt particles a viscous fluid and facilitates handling (Examples 1 to 3, Comparative Example 3, Reference Example). However, the oil formulation was not slimy after washing (reference example), and if it did not contain aloe juice, a refreshing feeling and moist feeling after use could not be obtained (Comparative Example 3).

  The cleaning composition containing salt granules, surfactant, and aloe juice (Examples 1 to 3) has no problems in handling, feeling of use, stability, and feeling after use. When the particle size was 300 μm or less, the rolling of the salt particles was smooth and could withstand facial cleansing of sensitive skin. In addition, in the cleaning composition of Example 3 having a high dokudami content, redness and itchiness were alleviated when continued to be used for 1 week in areas with eczema and itchiness.

  On the other hand, the one in which the dokudami powder is uniformly dispersed in the aloe juice lacks fluidity, so it is difficult to uniformly add and mix it into the detergent composition mainly composed of salt particles.
