Abstract

According to the present invention, black salts or black sugars use natural pigments, not artificial pigments such as tar, have the advantage of not irritating skin even when applied to the skin. As a black natural pigment, squid ink, which is an animal black pigment, or activated carbon, which is a carbon-based black pigment, is used. Thus, skin antioxidant and skin washing effects are ensured. The black salts or black sugars of the present invention use start to be coated with the black pigment which is insoluble. While the starch is coated on the surface of the salt or sugar, the insoluble black pigment is collected. Thus, the salts and sugars are expressed as black. A scrub composition comprising the black salts or black sugars of the present invention has an effect of exfoliating skin by salts or sugar grains when applied to the skin, because the black salts or black sugars have particle size of 0.1 to 2 mm and are coated with black natural pigments that are one or a mixture of two or more selected from the group consisting of insoluble animal black pigments and carbon-based black pigments through a starch coating layer as a medium. Since the black pigments are dissolved together with the starch layer and is present in the skin, there are skin antioxidant actions and an effect of effectively adsorbing and removing skin pollutants or sebum. In particular, the black salts or black sugars of the present invention is coated by the starch coating layer including the insoluble black pigments, and thus have reduced solubility compared to general salts or sugars. Accordingly, even when the black salts or black sugars are produced and stored as a scrub composition or are applied onto skin as a scrub agent, the salts or sugars are not completely dissolved but remain in a state of grains having skin keratin effects.

Description

Black salt or black sugar coated with black functional natural color and scrub composition containing the same {Scrub Composition Containing Functional Black Salt or Sugar}

The present invention relates to a black salt or black sugar coated with a black functional natural color and a scrub composition containing the same, and is a black prepared by coating the surface of salt or sugar with an insoluble animal black pigment or carbon black pigment using starch It relates to salt or sugar and a scrub composition comprising the same.

The scrub agent has the effect of being able to easily remove dead skin cells by applying it to the skin. The scrub agent contains small particles and causes friction during application to the skin to remove dead skin cells. The grains are mainly salt or sugar. Since the salt and sugar are water-soluble, when prepared as a water-soluble composition, they are dissolved and the exfoliating effect is reduced. Conventionally, in order to solve this problem, the salt or sugar was prepared in a supersaturated state or a non-aqueous substance was added to the composition so that the salt and sugar were not completely dissolved and existed in a granular state. If solubilized, the surface of the grains remains partially dissolved crystals, which has the advantage of reducing skin irritation.

The scrub agent may be classified as a type of cosmetic, but its main purpose is massage and washing. Therefore, the scrub agent has a characteristic of being applied to the skin and then removed in a short time, unlike general cosmetics that are applied to the skin and maintained for a long time. Accordingly, products that emphasize the individuality of the product in various colors are being released one after another, and various products in the form of a skin massage or a pack supplying nutritional ingredients are being released.

However, since salt or sugar used in the conventional scrub composition has a colorless crystal phase, there is a problem of implementing color by adding an artificial colorant. In particular, in order to manufacture a scrub with a black or dark color, the only thing to rely on the use of artificial pigments such as tar pigments was the only way to manufacture products against the preferences of consumers who prefer eco-friendly natural materials.

The patent documents and references mentioned in this specification are incorporated herein by reference to the same extent as if each document was individually and clearly specified by reference.

Korean Patent Publication 10-2010-013371 Korean Patent Registration 10-1876745

The present invention is to provide a black salt or black sugar coated with black natural pigment, which is any one or a mixture of two selected from the group consisting of insoluble animal black pigment and carbon-based black pigment, and a black scrub composition using the same.

Other objects and technical features of the present invention are presented in more detail by the following detailed description, claims, and drawings.

The present invention provides a black salt or black sugar coated with a black natural pigment, which is a mixture of any one or two selected from the group consisting of an insoluble animal black pigment and a carbon black pigment. The black salt or sugar has a starch coating layer formed on the outside of the salt or sugar grains, and the starch coating layer contains a black natural color, so that the black color is expressed. The insoluble animal black pigment of the present invention is squid ink, and carbon-based black cattle are activated carbon. The present invention is a black natural pigment selected from the group consisting of an insoluble animal black pigment and a carbon-based black pigment, a black natural pigment having a particle size of 0.1 to 2 mm through a starch coating layer or black salt coated on sugar Or it provides a scrub composition comprising black sugar.

In addition, the present invention is a step 1 of preparing a black natural pigment mixture; A second step of preparing a black cattle starch coating solution; A third step of preparing scrub salt or sugar having a particle size of 0.1 to 2 mm; Including black salt or black sugar for a scrub coated with black natural coloring, including a fifth step of preparing a scrub composition by mixing black sugar, alcohol, wax, oil, moisturizer, detergent, preservative, and surfactant It provides a method for preparing a scrub composition.

The black salt or black sugar of the present invention has the advantage of not irritating the skin even when applied to the skin because it uses a natural color rather than an artificial color such as tar, and as the black natural color, squid ink or carbon-based black pigment, activated carbon It has antioxidant and skin cleansing effects.

The black salt or sugar of the present invention uses starch to coat the black powder, which is insoluble. The starch is coated on the surface of the salt or sugar and collects insoluble black pigment, so that the salt and sugar are expressed in black.

The scrub composition containing black salt or black sugar of the present invention includes a black natural pigment selected from the group consisting of insoluble animal black pigments and carbon-based black pigments, particles of 0.1 to 2 mm through the starch coating layer. It contains black salt or black sugar coated with salt or sugar having a size, so when applied to the skin, it has an effect of exfoliating the skin by salt or sugar grains, and the black pigment is dissolved together with the starch layer to exist in the skin. Therefore, it has the effect of effectively adsorbing and removing skin contaminants or sebum as well as skin antioxidant activity.

In particular, the black salt or black sugar of the present invention is coated by a starch coating layer containing the insoluble black pigment, so that the solubility is inhibited compared to ordinary salt or sugar. Therefore, even if it is prepared as a scrub composition and stored or applied to the skin as a scrub agent, salt or sugar does not completely dissolve and remains in a granular state having a keratin effect.

1 shows a method of preparing a scrub composition containing black salt or black sugar of the present invention.
Figure 2 shows the black salt or black sugar coated with the black natural color of the present invention. The picture on the right of panel A) shows black salt and the picture on the left shows black sugar. The figure on the right of panel B) shows the results of the solubility evaluation of black salt, and the figure on the left shows the solubility results of black sugar.

The present invention provides black salt or black sugar coated with a black natural pigment, which is any one or a mixture of two selected from the group consisting of an animal black pigment and a carbon-based black pigment.

The black natural pigment may be a vegetable black pigment, an animal black pigment, and a carbon-based black pigment. The vegetable black cattle may be anthocyanin or tannin-based, and the animal black cattle may be melanin-based squid ink, and are known to exhibit immune function activation and anticancer activity, and the carbon-based black cattle may be activated carbon. In the present invention, animal black cattle and carbon black cattle are used. Since the vegetable black pigment has a property of changing color according to the acid concentration, there is a fear that the color may change depending on the storage condition when a composition is prepared using the pigment. On the other hand, the animal black pigment has the advantage that the color does not change depending on the pH, but it is insoluble, so there is a limitation in preparing it as an aqueous phase component when preparing the composition. Activated carbon used as the carbon-based black cattle is a kind of charcoal left by burning wood, and has excellent adsorption effect and is used as a material for various filters. The excellent adsorption performance of the activated carbon is also attracting attention in the beauty industry. When the activated carbon is finely pulverized and applied to the skin, it is known to have a skin cleaning effect in which contaminants from the skin are adsorbed and removed, and it is known that it can be used to remove skin sebum.

For reference, the carbon-based black pigment has carbon nanotubes. The carbon nanotubes are supplied by extraction from coal, etc., and similar to the activated carbon, they have a property of adsorbing various contaminants, but their use is limited due to research results showing that they are cytotoxic.

In the case of a scrub agent applied to the skin, when the amount of the oily component increases, the feeling of use decreases and the scrub effect also decreases. Conventionally, in order to overcome the above shortcomings, insoluble components were mostly dissolved by using a surfactant or the like. However, the above method eventually increases the amount of artificial chemicals in the scrub composition, contrary to the preference of consumers who prefer to use eco-friendly natural substances. In particular, the squid ink and activated carbon, which are the black natural pigments of the present invention, are insoluble and thus it is very difficult to disperse in an aqueous phase. If the above ingredients are not properly dispersed, they may precipitate in the product and deteriorate the palatability of the product. The squid ink is a natural substance that is safe enough to be used as a food additive, and has an antioxidant effect, so it is also used for skin care. However, since it is insoluble, there is a limit to its application as a pigment. In addition, in the case of the activated carbon, which is a carbon-based black pigment of the present invention, similarly to the squid ink, it is insoluble and thus it is difficult to disperse in the aqueous phase.

Accordingly, in the present invention, black salt or sugar was prepared by coating the black pigment on salt or sugar, and a scrub composition was prepared using this. As described above, since the black pigment of the present invention is insoluble, it is not directly coated on the surface of salt or sugar in a simple solid or liquid state. Therefore, there is a need for a medium capable of binding the black pigment to the surface of the salt or sugar. In the present invention, starch, which is harmless to the human body and is edible, was used as the medium. The starch is a polymeric carbohydrate in which a large number of glucose units are linked by glycoside bonds, and may be present in the form of a viscous loose gel by absorbing moisture. When the starch is used, the insoluble black pigment may be collected and coated on the surface of salt or sugar. The starch may be extracted from various crops such as corn, wheat, rice, and potatoes, and corn starch is preferably used. In the black salt or black sugar of the present invention, salt or sugar grains exist inside, and a starch coating layer in which black spots are collected exists on the outside, so that the salt or sugar expresses black color. The starch coating layer has the effect of expressing the color of salt or sugar and controlling the solubility. When used on the skin as a scrub composition, the starch layer containing the pigment is dissolved in contact with the skin, thereby exerting the unique physiological activity of each black pigment. It has the effect of delivering on. When the black salt or black sugar is used in a scrub agent, it must exist in the form of particles of an appropriate size that can cause friction with skin dead skin cells and remove them. Salt and sugar are substances that have high solubility in water. Therefore, if the solubility of salt and sugar is not adjusted, the salt and sugar are all dissolved in the scrub composition, resulting in insignificant skin exfoliating effect. To this end, in the prior art, a scrub agent was prepared as an oily component to prevent dissolution of the salt and sugar. However, as the demand for skin moisturizing, skin cleansing, and supply of skin nutrients for the scrub agent increased by consumers, the content of water-based ingredients for this increased. This led to the problem of lowering the stability and dispersibility of the scrub agent, and various additives began to be used to solve this problem. However, the use of various artificial additives as described above has a limitation in that it cannot meet the preferences of consumers who prefer eco-friendly natural materials.

When the starch coating layer is used for the production of black salt or black sugar as in the present invention, the degree of dissolution of salt or sugar is adjusted according to the drying degree of the starch coating layer, the thickness of the starch coating layer, and the density of the black pigment collected in the starch coating layer. do. Therefore, even if the black salt or black sugar of the present invention is used in a scrub agent containing an oily component and an aqueous phase component in a certain ratio, it has the advantage of maintaining the state of particles having a scrub effect for a considerable time. In addition, when the black salt or black sugar of the present invention is included in the scrub agent and applied to the skin, the genital starch coating layer dissolves in a situation where physical stimulation such as rubbing is applied, and the salt or sugar inside the coating layer is partially dissolved. It has the effect of providing minerals and cleaning the skin due to sugar.

The starch coating layer is preferably formed to a thickness of 5 to 10% of the size of the salt and sugar particles. If the thickness of the starch layer is too thin, there may be a problem in the expression of black color due to the pigment, and if the thickness of the starch layer is too thick, there may be a problem with dispersibility in the scrub agent due to increased viscosity, and drying time may take longer during manufacture. .

The present invention is a black natural color pigment selected from the group consisting of an animal black pigment and a carbon-based black pigment, or a black natural pigment having a particle size of 0.1 to 2 mm through the starch coating layer, and black salt or black coated on sugar It provides a scrub composition comprising sugar, wherein the scrub composition further comprises alcohol, wax, oil, moisturizer, detergent, preservative, and surfactant.

The scrub composition includes black salt or black sugar, an oily component, an aqueous phase component, and a surfactant. The oil phase component may include alcohol, wax, and oil, and the aqueous phase component may include a moisturizing agent, a detergent, and a preservative.

Since the black pigment and the starch coating layer have been described above, they are not described in order to avoid duplication of the present specification. The alcohol has an effect of improving the dispersibility of the black salt or black sugar in the scrub composition by improving the solubility of the black salt or black sugar. On the other hand, the oil prevents the black salt or black sugar from being excessively dissolved in the scrub composition, resulting in deterioration of the keratin effect. Therefore, it is important that the content of the alcohol component and the oil component is appropriately adjusted so that the black salt or black sugar is properly dispersed in the scrub composition, and the scrub effect is not deteriorated due to excessive dissolution. The wax plays an important role in the formation of the scrub formulation. The amount of the wax is too small and it is manufactured in a thin gel formulation, so that the feeling of use may be deteriorated. If there are too many wax components, it may be too hard to use as a scrub agent. The moisturizing agent can be used without limitation as long as it is a polyol having a skin moisturizing effect. The polyols have a lower degree of dissolving the black salt or black sugar than water, and thus have an advantage in maintaining the black salt or black sugar in the form of particles in the scrub composition. The detergent may be a surfactant having a skin cleaning effect. The preservative is for inhibiting the growth of microorganisms and may be used without limitation as long as it does not have skin irritation and can be used as a cosmetic composition. The surfactant is used for the purpose of improving the dispersibility of the oil phase component and the aqueous phase component. The surfactant may be used in combination with the detergent, but if dispersibility needs to be further improved, it is worth considering applying a separate surfactant.

The scrub composition containing black salt or black sugar of the present invention can be prepared by the following manufacturing method:

Step 1: Mixing black natural pigment, which is a mixture of any one or two selected from the group consisting of animal black pigment and carbon-based black pigment, and distilled water at a weight ratio of 0.5 to 2: 10 (black natural color: distilled water), to prepare a black natural color mixture. Manufacturing steps;

The second step: preparing a black cattle starch coating solution by mixing the black natural colorant and starch to a weight ratio of 0 to 2:4 (black natural color: starch) in the black natural color mixture;

Third step: preparing salt or sugar for scrub by pulverizing salt or sugar to have a particle size of 0.1 to 2 mm;

Step 4: Mix the black cattle starch coating solution and the scrub salt or sugar at a weight ratio of 0.5 to 2:25 (black starch coating solution: scrub salt or sugar), stir, and dry the scrub coated with black natural color. Preparing dragon black salt or black sugar;

Step 5: preparing a scrub composition containing black salt or black sugar by mixing black salt or black sugar, alcohol, wax, oil, moisturizing agent, detergent, preservative, and surfactant for the scrub coated with the black natural color. step.

Step 1: Preparing a black natural pigment mixture

First, a powdery animal black pigment or carbon-based black pigment is prepared. Distilled water is added to the black pigment powder to prepare a black natural pigment mixture. The black pigment and distilled water are mixed in a weight ratio of 0.5 to 2: 10 (black natural color: distilled water), and preferably, mixed in a weight ratio of 1: 10. Since the black pigment is insoluble, the degree of dispersion by distilled water may be insignificant, but it is important to stir as much as possible to prevent excessive aggregation of the pigment when mixed with starch. If the black pigment is used in a weight ratio of less than 0.5:10, it is difficult to express black color, and if the black pigment is used in a weight ratio exceeding 2:10, the black pigment is excessively aggregated, making it difficult to disperse the pigment when starch is added.

Step 2: preparing a black cattle starch coating solution

While stirring the prepared black natural pigment mixture, starch is added to prepare a black cattle starch coating solution. The black natural colorant and starch are mixed in a weight ratio of 0.5 to 2:4 (black natural colorant: starch). Preferably, it is mixed so as to have a weight ratio of 1: 4 (black natural color: starch). If the starch is used in a weight ratio of less than 0.5:4, the viscosity of the black cattle starch coating solution is too low, and it is difficult to control the thickness of the coating layer when coating it on salt or sugar particles, and it takes more time to dry. When the amount of starch exceeds the 2:4 weight ratio, the viscosity of the black cattle starch coating solution is too high, making it difficult to coat salt or sugar particles. The black cattle starch coating solution should be thoroughly stirred continuously so that the black pigment is completely dispersed in the starch.

Step 3: preparing salt or sugar for scrubbing

To prepare a scrub salt or sugar to be coated with the black cattle starch coating solution. The scrub salt or sugar is pulverized so that the particle size is 0.1 to 2 mm. Preferably, the scrub salt or sugar is pulverized so that the particle size is 0.3 to 1 mm. More preferably, it is pulverized so that the particle size is 0.4 to 0.6 mm.

It is preferable to use a natural sea salt rich in minerals as the salt. The salt and sugar are mixed with the following black cattle starch coating solution, and the pulverized salt or sugar particles may be dissolved in this process. Therefore, it is preferable that the scrub salt or sugar to be coated with the black cattle starch coating solution is pulverized to have a slightly larger particle size than the black salt or black sugar particles that are finally contained in the scrub agent to remove dead skin cells. If the scrub salt or sugar to be coated with the black cattle starch coating solution is pulverized to a particle size of less than 0.1 mm, it is excessively dissolved in the mixing process with the black cattle starch coating solution, making it difficult to produce black salt and black sugar having a dead skin effect. When pulverized to exceed 2 mm, even if the scrub salt or sugar is partially dissolved in the mixing process with the black cattle starch coating solution, the particles are too large to reduce the feeling of use of the scrub agent.

Step 4: preparing black salt or black sugar for scrub

The black cattle starch coating solution and the scrub salt or sugar are mixed in a weight ratio of 0.5 to 2:25 (black starch coating solution: scrub salt or sugar), stirred and dried, and then black salt for scrub coated with black natural color or Make black sugar. Preferably, the mixture is stirred in a weight ratio of 1: 25 (black starch coating solution: scrub salt or sugar). If the black cattle starch coating solution is used in a weight ratio of less than 0.5:25, the black cattle starch coating solution may not be evenly coated on all salt or sugar grains, and even if it is coated, the thickness of the coating layer may be too thin, so storage performance may be reduced. In addition, if the black cattle starch coating solution is used in excess of 2:25 weight ratio, it takes more time to dry, and a color coagulation material without salt or sugar is generated, and a post process for removing this may be further required.

The mixing process of the black cattle starch coating solution and salt or sugar is a step in which the black cattle starch coating solution is coated on the salt or sugar particles, but is also a process in which a part of the salt or sugar particles is dissolved. The salt and sugar dissolved during the mixing process decreases the particle size, but the rough part of the surface dissolves and disappears first, resulting in a spherical particle shape, thereby reducing skin irritation during scrubbing for exfoliating the skin. The salt or sugar particles crushed to a particle size of 0.1 to 2 mm through the coating process are prepared from black salt or black sugar having a particle size of 0.1 to 0.3 mm. If the particle size of the black salt or black sugar is less than 0.1 mm, the effect of removing dead skin cells from the scrub agent is insignificant, and when the particle size exceeds 0.3 mm, the use of the scrub agent may cause a feeling of heterogeneity, thereby reducing the feeling of use.

Step 5: preparing a scrub composition comprising black salt or black sugar

A scrub composition containing black salt or black sugar is prepared by mixing the prepared black salt or black sugar, alcohol, wax, oil, moisturizer, detergent, preservative, and surfactant for the scrub coated with black natural color.

The scrub composition may contain alcohol, wax, and oil as an oily component. The alcohol is a higher alcohol and one or more selected from monohydric alcohols having 6 to 22 carbon atoms may be used. The alcohol having 16 to 22 carbon atoms may be any one or a mixture of two or more selected from the group consisting of cetyl alcohol, cetostearyl alcohol, isostearyl alcohol, stearyl alcohol, behenyl alcohol, and batyl alcohol.

The scrub composition may include a moisturizing agent, a detergent, and a preservative as an aqueous component. The moisturizing agent is extracted from a plant, and may be used cypress tree extract, Eoseongcho extract, or propolis extract, and polyol and polyacrylic acid polymer including glycerol, propylene glycol, and acrylate copolymer may be further used.

The detergent may be a surfactant, and the surfactant may be sodium laureth sulfate, acrylate copolymer, cocamidoprovelbetaine, ammonium uryl sulfate, or polyglumic phase.

The preservatives are alkyl esters of para-hydroxybenzoic acid, hydantoin derivatives, propionates, and various quaternary ammonium compounds, phenoxyethanol, methylparaben (methyl paraoxybenzoate), propylparaben (propyl paraoxybenzoate). ), imidazolidinyl urea, sodium dehydroacetate and a mixture of two or more selected from the group consisting of benzyl alcohol.

Thereafter, the oil phase component and the aqueous phase component are stirred together with a surfactant, and the black salt or black sugar is added and stirred. The scrub composition of the present invention sufficiently uses the oily component so that the black salt or black sugar does not dissolve excessively and maintains the particulate form. The black salt or black sugar of the present invention is coated with a starch layer containing black cattle, so the solubility is controlled to be low compared to general salt or sugar. Therefore, even if it is contained as a constituent of a scrub formulation in which an oily component and an aqueous phase component are mixed, the skin exfoliation effect can be maintained without problems. In addition, in order to improve the storage properties of the scrub agent, it may be prepared by adding the black salt or black sugar so that it becomes slightly supersaturated in the scrub agent.

Since the scrub composition of the present invention contains black salt or black sugar as scrub particles, it has an immune activation effect, anticancer effect, and skin cleaning effect due to black pigment, as well as mineral supply effect of salt, strong moisture absorption effect of sugar, scrub It has the effect of exfoliating and massaging by the physical friction of black salt or black sugar, which is a particle.

Example

Example 1: Preparation of black salt or black sugar for scrub coated with black natural color

Activated carbon, a carbon-based pigment, was used for natural pigments containing black natural pigments. The activated carbon used in the present invention is high purity bamboo activated carbon. The black natural pigment can be replaced with squid ink, which is an animal black pigment. The activated carbon is composed of carbon, whereas the squid ink is mainly composed of melanin, and has a difference in chemical composition, but both components are insoluble components and can be dispersed by starch, and can be used as a scrub composition to develop black color, And it is because it is included in the scrub composition and can be used as a functional component such as skin antioxidant or skin waste removal.

10 ml of distilled water was added to 1 g of the high-purity bamboo activated carbon and mixed. To the mixture was added 4 g of corn starch and mixed well to prepare a black beef starch mixture. Salt and sugar were pulverized to have a diameter of 0.1 to 2 mm. 2 ml of the black cattle starch mixture was added to 50 g of salt and sugar whose particle size was controlled, followed by stirring and mixing to coat the pigment. The dye-coated salt or sugar was dried in a dryer at 50° C. for 1 hour to prepare black salt or black sugar for scrub coated with a particulate black natural dye (FIG. 2).

The solubility was tested for the obtained black salt or black sugar for scrub (see Fig. 2). As a result of dissolving the black salt or black sugar for scrubbing in 20 ml of distilled water, it was confirmed that some of the pigment coated on the salt or sugar was dissolved and had a black color, and some did not dissolve and existed in a granular state. Black pigment separated from some starch coating layers is observed, but it is judged that the separation will not be severe in the actual scrub composition with higher viscosity.

Example 2: Preparation of functional black scrub composition

In order to prepare a functional black scrub composition, black salt or black sugar, alcohol, wax, oil, moisturizer, detergent, preservative, and surfactant for the scrub coated with the black natural pigment were mixed.

First, an oily component including alcohol, wax, and oil was prepared. The wax was dissolved at around 70°C and then cooled to 40 to 50°C. Alcohol and oil were added to the cooled wax and mixed. During the mixing process, the temperature (40 to 50°C) was maintained to prevent excessive coagulation of the wax and excessive evaporation of the alcohol component. The oily component was prepared by mixing alcohol: wax: oil in a weight ratio of 1:1: 3 to 4 (alcohol: wax: oil).

Next, an aqueous phase component including a moisturizer, a detergent, and a preservative was prepared. The aqueous phase component was prepared by mixing a moisturizing agent, a detergent, and a preservative in a weight ratio of 94:3:3 (moisturizing agent: detergent: preservative). It was prepared by adding 20 parts by weight of the oily component, 5 parts by weight of the aqueous phase component, and 3 parts by weight of a surfactant based on 100 parts by weight of the black salt or black sugar for the scrub. First, the oily component, the aqueous phase component, and the surfactant were mixed, and then the black salt or black sugar for scrub was added, stirred, and then stored at room temperature. In the scrub composition prepared by the above method, it was confirmed that the black salt or black sugar grains for the scrub were wetted by the oily component and the aqueous phase component to maintain a moist state. When the total amount of the oily component and the aqueous phase component exceeds 25 parts by weight, the black salt or black sugar for the scrub may be excessively dissolved, and in particular, the dissolved sugar is hardened and storage is difficult. If less than 3 parts by weight of the surfactant is used, the dispersibility of the aqueous phase component and the oil phase component may be reduced, and the cleaning effect may be insignificant. Even if it is used in excess of 5 parts by weight, the degree of improvement in dispersibility and cleaning effect is insignificant.

The specific embodiments described herein are meant to represent preferred embodiments or examples of the present invention, and the scope of the present invention is not limited thereby. It will be apparent to those skilled in the art that variations and other uses of the present invention do not depart from the scope of the invention described in the claims of this specification.
