Description

[Technical field]

[0001] The present invention relates to a glass composition for detergents and a method for producing glass powder for detergents using the same. [Background technology]

[0002] The process of removing stains from textiles and clothing is usually called washing, while the process of removing stains from dishes is called cleaning.

[0003] These washing and cleaning methods involve dispersing surfactants in the water to increase the alkalinity of the water and remove contaminants.

[0004] Laundry and cleaning methods using synthetic detergents use a large amount of water, and therefore, although they are effective in removing aqueous contaminants, there is a limit to their ability to remove oily contaminants.

[0005] In addition, conventional synthetic detergents use linear alkylbenzenes, anionic surfactants, builders, etc. to wash, clean and dry dirt (dirty grime) that has adhered to clothes and tableware.

[0006] However, when washing and cleaning are carried out using conventional synthetic detergents, there is a problem that the surfactants are insoluble in water and cause eutrophication, resulting in environmental pollution.

[0007] Furthermore, although a conventional technique using a glass composition as a detergent is known, if undissolved glass particles remain on fibers or the like after washing, this can be problematic from an environmental perspective.

[0008] In addition, since conventional glass compositions have a high SiO2 content, they do not dissolve sufficiently during a short washing time, leaving a large amount of residual material.

[0009] Furthermore, the use of Ag2O increases raw material costs and may pose environmental concerns. [Prior art documents] [Patent documents]

[0012] Furthermore, an object of the present invention is to provide an environmentally friendly glass composition for detergents, which is capable of producing highly concentrated eluate using two glass compositions, and a method for producing environmentally friendly glass powder for detergents using the same.

[0013] Another object of the present invention is to provide an environmentally friendly glass composition for detergents, which allows a certain amount of glass to be used repeatedly and maintains constant washing performance even up to 40 times, and a method for producing an environmentally friendly glass powder for detergents using the same.

[0014] The object of the present invention is not limited to the object mentioned above, and other objects and advantages of the present invention not mentioned can be understood from the following description and can be more clearly understood from the embodiments of the present invention. Also, it can be easily understood that the object and advantages of the present invention can be realized by the means and combinations thereof as set forth in the claims. [Means for solving the problem]

[0015] The glass composition for an environmentally friendly detergent according to the present invention and the method for producing an environmentally friendly glass powder for a detergent using the same are capable of adjusting pH by using a borate-based first glass composition and a silicate-based second glass composition, and are + , Na + , Ca 2+ , Mg 2+ The elution of ions such as these is maximized, making it possible to produce eluted water with high concentrations.

[0016] As a result, the environmentally friendly glass composition for detergents according to the present invention and the method for producing environmentally friendly glass powder for detergents using the same can repeatedly use a certain amount of glass, and can maintain constant washing performance even up to 40 times or more.

[0017] That is, in the present invention, an environmentally friendly glass composition for detergents was developed that uses two glass compositions and can provide uniform washing performance even after 40 or more washing cycles.

[0018] For this purpose, an environmentally friendly glass composition for a detergent according to an embodiment of the present invention includes a mixture of a first glass composition and a second glass composition, the first glass composition including, based on 100% by weight of the first glass composition, 60-70% by weight of B2O3, 1-4% by weight of Al2O3, 5-9% by weight of CaO, and 15-30% by weight in total of K2O and Na2O, and the second glass composition including, based on 100% by weight of the second glass composition, 65-70% by weight of SiO2, 5-9% by weight of CaO, and 21-28% by weight in total of K2O and Na2O.

[0021] Equation 1: ([CaO]+[MgO]) / ([K2O]+[Na2O])<0.53 (In the formula, [ ] indicates the weight percent of each component.)

[0022] Furthermore, CaO, MgO, K2O, Na2O, and B2O3 contained in the first glass composition may satisfy the following formula 2.

[0025] Formula 3: ([CaO]+[MgO]+[K2O]+[Na2O]) / [SiO3]≧0.42 (In the formula, [ ] indicates the weight percent of each component.) Effect of the Invention

[0026] According to the present invention, it is possible to provide a new solution that realizes cleaning power equal to or superior to that of ordinary detergents.

[0027] Furthermore, since the present invention does not contain a surfactant, it is possible to shorten the rinsing process and reduce the amount of water used during washing.

[0028] Furthermore, according to the present invention, when a normal detergent and elution water are used together, the washing efficiency can be increased, resulting in an energy saving effect.

[0029] In addition, according to the present invention, when a detergent composition containing two glass compositions is used as an environmentally friendly laundry detergent or cleaning aid and is added to the automatic detergent compartment of a washing machine, glass can be dissolved homogeneously and consistently, thereby making it possible to extend the recurring period and maintain high reliability even during repeated washing processes.

[0032] The above-mentioned objects, features and advantages will be described in detail below with reference to the accompanying drawings, so that those skilled in the art to which the present invention pertains can easily implement the technical concept of the present invention. In describing the present invention, if a detailed description of known techniques according to the present invention is deemed to obscure the gist of the present invention, the detailed description will be omitted. Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. The same reference numerals in the drawings are used to indicate the same or similar components.

[0033] As used herein, singular expressions include plural expressions unless the context clearly indicates otherwise. In this application, the terms "comprise" or "include" (comprise; constitute; construct; set; include; contain; contain) should not be interpreted as including all of the multiple components or multiple steps described in the specification, but should be interpreted as including some of the components or some steps that may not be included, or may further include additional components or steps.

[0034] Hereinafter, a glass composition for detergent according to some embodiments of the present invention and a method for manufacturing a glass powder for detergent using the same will be described.

[0035] Glass composition for detergent The present invention aims to provide an environmentally friendly laundry detergent technology that combines two elutable glass compositions to produce weakly alkaline water at a pH level of 9.5 to 10.0 repeatedly more than 40 times.

[0036] The glass composition for detergent according to the present invention includes a first glass composition (borate composition) and a second glass composition (silicate composition). The silicate composition dissolves within 5 minutes when washing water is supplied to increase the pH value, and has a function of reducing OH. - It forms a large amount of ions to break down proteins and complex contaminants during the washing process. The borate compound dissolves in water to form B(OH)3 and B(OH)4. - It produces ions and maintains the pH of water at a level of 9 to 9.5. If the detergent glass composition is composed only of a silicate composition, the pH becomes high, at 11 or more, and there is a drawback in that discoloration occurs in dye contaminants, but the present invention adds a borate composition to solve these drawbacks. The detergent glass composition according to the present invention has the effect of maintaining its detergency even when the solid glass is dissolved in water and then re-dissolved, and maintaining its washing performance during a total of 40 cycles. The detergent composition according to the present invention has a longer lasting performance than detergent compositions composed solely of a borate composition or a silicate composition.

[0037] The present invention includes a first glass composition (a borate composition) to provide a bleaching effect and a pH adjusting function.

[0038] In the first glass composition, the contents of alkali oxides (NaO, KO) and alkaline earth oxides (CaO, MgO) are important in order to maximize the solubility of the borate glass and to produce a solid (bulk) glass that can maintain its shape to some extent in air.

[0039] Unlike alkali and alkaline earth oxides, Al2O3 is used as a component to control the dissolution of glass, and is added in small amounts to maintain the shape of glass in air. In the case of B2O3, the main component of glass, it dissolves in water and becomes B(OH)3 and B(OH)4. - It forms ions and helps to wash off the color components during washing. It also has B(OH)3 and B(OH)4 - Through ionic interactions, the pH of the washing water (elution water) is maintained at 9.5~10.0, preventing discoloration of dye contaminants during the washing process.

[0040] In addition, when alkali and alkaline earth elements are dissolved in water, they react with OH. - It forms ions which aid in the washing of protein and fat soluble contaminants.

[0041] Next, the second glass composition (silicate composition) included in the present invention contributes to washing protein and fat-soluble contaminants and exhibiting antibacterial properties.

[0042] The second glass composition has better chemical durability and is less likely to dissolve in water than the first glass composition which is a borate composition.

[0043] However, if the content of alkali and alkaline earth elements in the glass structure is 30% by weight or more, the dissolution of alkali and alkaline earth ions can occur very quickly. When alkali and alkaline earth ions are dissolved, they are converted from water to OH. - This causes a large amount of ions to be generated. - Ions destroy the structure of proteins and fat-soluble contaminants, contributing to the washing action. An environmentally friendly detergent that utilizes these principles is the "alkaline ionized water laundry detergent." However, if only a silicate composition such as the second glass composition is used as a detergent, the pH of the elution water (washing water) can become as high as 11 or more, which can lead to discoloration of the pigment components. Therefore, in the present invention, a detergent is constructed by combining both the first glass composition (borate composition) having a pH adjusting function and the second glass composition (silicate composition).

[0044] For this purpose, an environmentally friendly glass composition for a detergent according to an embodiment of the present invention includes a mixture of a first glass composition and a second glass composition, the first glass composition including, based on 100% by weight of the first glass composition, 60-70% by weight of B2O3, 1-4% by weight of Al2O3, 5-9% by weight of CaO, and 15-30% by weight in total of K2O and Na2O, and the second glass composition including, based on 100% by weight of the second glass composition, 65-70% by weight of SiO2, 5-9% by weight of CaO, and 21-28% by weight in total of K2O and Na2O.

[0045] Here, the first glass composition and the second glass composition each preferably contain CaO and MgO in a total amount of less than 10% by weight.

[0046] CaO, MgO, K2O, and Na2O contained in the first glass composition may satisfy the following formula 1.

[0047] Equation 1: ([CaO]+[MgO]) / ([K2O]+[Na2])<0.53 (In the formula, [ ] indicates the weight percent of each component.)

[0048] Furthermore, CaO, MgO, K2O, Na2O, and B2O3 contained in the first glass composition may satisfy the following formula 2.

[0049] Formula 2: ([CaO]+[MgO]+[K2O]+[Na2O]) / [B2O3]≧0.37 (In the formula, [ ] indicates the weight percent of each component.)

[0050] Also, preferably, CaO, MgO, K2O, Na2O, and SiO2 contained in the second glass composition can satisfy the following formula 3.

[0051] Formula 3: ([CaO]+[MgO]+[K2O]+[Na2O]) / [SiO3]≧0.42 (In the formula, [ ] indicates the weight percent of each component.)

[0052] Hereinafter, the role and content of each component of the environmentally friendly detergent glass composition according to the embodiment of the present invention will be described in detail.

[0053] B2O3 is a glass former that is typically used along with SiO2, P2O5, etc. It is a key component that enables sufficient vitrification and forms the core framework in the structure of glass. B2O3 exists mainly in glass in the form of BO3 or BO4, and in the form of 3- or 4-coordination, and also plays a role in lowering the melting temperature of glass.

[0054] Glass containing a large amount of B2O3 is weaker in water than SiO2-based glass, and maximizes the solubility of glass. In addition, B2O3 has a bleaching effect during solubility and acts as a pH buffer, so it does not cause discoloration of pigment contaminants.

[0055] Therefore, it is preferable that B2O3 is added in a content ratio of 60 to 70 wt% in the first glass composition. If the content of B2O3 is less than 60 wt%, it may be difficult to exert the bleaching effect and to ensure the cleaning power. On the other hand, if the content of B2O3 exceeds 70 wt%, a phenomenon may occur in which the water resistance is reduced due to the nature of the element itself due to structural problems of B and P in the network-forming structure.

[0056] SiO2 is the most typical glass former oxide, and it is an ingredient that needs to be added in small amounts to increase vitrification. If a large amount of SiO2 is added, it increases the water resistance of glass and plays a role in controlling leaching. It also increases the melting temperature of glass.

[0057] Therefore, SiO2 is preferably added to the second glass composition in a content ratio of 65 to 70 wt%. If SiO2 is added in a large amount exceeding 70 wt%, the viscosity of the glass increases when it melts, which causes a problem of reduced workability and yield during the cooling process. Conversely, if SiO2 is added in an amount less than 65 wt%, the structure of the glass is weakened, which causes a problem of reduced water resistance.

[0058] Al2O3 is the most typical intermediate oxide, and even if only a small amount is added to the first glass composition (borate composition), it increases the water resistance of the glass and controls dissolution. However, in the present invention, if 5 wt% or more is added based on 100 wt% of the first glass composition, dissolution of the borate-based glass becomes very difficult. Therefore, in the present invention, the content of Al2O3 in the first glass composition is limited to less than 5 wt%. Specifically, the first glass composition contains 1 to 4 wt% of Al2O3.

[0059] Na2O and K2O are alkali oxides that act as non-crosslinking network modifiers in glass compositions. Although these components cannot be vitrified by themselves, they can be vitrified when mixed in certain proportions with glass formers such as SiO2, B2O3, P2O5, V2O5, and Ga2O3.

[0060] Alkaline ions are H3O + It is ion-exchanged with OH and dissolved in water. - It is the main component that exerts cleaning power by forming ions. However, if a large amount of alkaline components are included, OH - As the concentration of ions increases, the pH increases to 10 to 11 or higher, which causes discoloration of the pigment components.

[0061] Therefore, in the present invention, the above-mentioned shortcomings are improved by combining a silicate-based glass having a controlled content of alkali oxides with a borate-based glass having a controlled content of alkali oxides.

[0062] In particular, since the elution characteristics of glass vary greatly depending on the content ratio of alkali oxide, B2O3, and SiO2, adjusting the content ratio is one of the important factors in the present invention.

[0063] In the present invention, a glass composition that is excellent in initial elution characteristics and easily elutes even when used continuously has been confirmed through experiments. In the present invention, the first glass composition contains 15 to 30 wt % of an alkali oxide, and the second glass composition contains 21 to 28 wt % of an alkali oxide. The alkali oxide in the present invention contains Na2O and K2O.

[0064] In each glass composition, when Na2O and K2O are added in a total amount less than the minimum amount, it may be difficult to ensure cleaning durability. Conversely, in each glass composition, when Na2O and K2O are added in a total amount more than the maximum amount, OH - High concentrations of ions can cause discoloration of pigment components.

[0065] Alkaline earth oxides such as CaO and MgO basically act as non-crosslinking network modifiers, similar to alkali oxides in glass. Therefore, alkaline earth oxides such as CaO and MgO weaken the glass structure. However, compared to alkali ions, they weaken the glass structure to a lesser extent, so when alkaline earth oxides are added to borate-based glass, the water resistance may actually increase slightly.

[0066] The dissolution rate of alkaline ions is similar to that of boron (B) ions, so it is possible to dissolve it consistently and it can be used continuously as a detergent and laundry aid. In this case, alkaline earth oxides are added to control and adjust the dissolution rate of ions. In addition, alkaline earth oxides, like alkaline oxides, dissolve in water and form OH. -It also forms ions, which makes it useful for laundry.

[0067] In the present invention, the first glass composition and the second glass composition each contain 5 wt % or more of CaO, specifically, the CaO content in each glass composition is 5 to 9 wt %.

[0068] Preferably, each of the first glass composition and the second glass composition may further contain 0 to 4 wt % MgO, although it is preferable that each of the first glass composition and the second glass composition contains less than 10 wt % CaO and MgO in total.

[0069] Furthermore, CaO, MgO, K2O, and Na2O contained in the first glass composition may satisfy the following formula 1.

[0070] Equation 1: ([CaO]+[MgO]) / ([K2O]+[Na2O])<0.53 (In the formula, [ ] indicates the weight percent of each component.)

[0071] In addition, CaO, MgO, K2O, Na2O, and B2O3 contained in the first glass composition may satisfy the following formula 2.

[0072] Formula 2: ([CaO]+[MgO]+[K2O]+[Na2O]) / [B2O3]≧0.37 (In the formula, [ ] indicates the weight percent of each component.)

[0073] Furthermore, CaO, MgO, K2O, Na2O, and SiO2 contained in the second glass composition may satisfy the following formula 3.

[0074] Formula 3: ([CaO]+[MgO]+[K2O]+[Na2O]) / [SiO3]≧0.42 (In the formula, [ ] indicates the weight percent of each component.)

[0075] The reason for adjusting the content of each component as described above is to increase the degree of ionic bonding in the glass by increasing the content of the network modifier, thereby increasing the elution property.

[0076] Manufacturing method of glass powder for detergent DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a method for manufacturing an environmentally friendly glass powder for detergent according to an embodiment of the present invention will be described with reference to the accompanying drawings.

[0077] FIG. 1 is a process flow diagram showing a method for producing an environmentally friendly glass powder for detergent according to an embodiment of the present invention.

[0078] As shown in FIG. 1, a method for manufacturing an eco-friendly glass powder for detergent according to an embodiment of the present invention includes a mixing step (S110), a melting step (S120), a cooling step (S130), and a grinding step (S140).

[0079] mixture In the mixing step (S110), the first glass composition and the second glass composition are mixed in the above-mentioned composition ratio and stirred to form a glass composition.

[0080] As described above, the first glass composition contains, based on 100% by weight, 60 to 70% by weight of B2O3, 1 to 4% by weight of Al2O3, 5 to 9% by weight of CaO, and a total of 15 to 30% by weight of K2O and Na2O, and the second glass composition contains, based on 100% by weight of the second glass composition, 65 to 70% by weight of SiO2, 5 to 9% by weight of CaO, and a total of 21 to 28% by weight of K2O and Na2O.

[0081] Melting In the melting step (S120), the glass composition is melted.

[0082] In this stage, melting is preferably carried out at 700 to 1,100°C for 1 to 60 minutes. If the melting temperature is less than 700°C or the melting time is less than 1 minute, the glass composition is not completely melted, which may cause immiscibility of the glass melt. On the other hand, if the melting temperature exceeds 1,100°C or the melting time exceeds 60 minutes, excessive energy and time are required, which is not economical.

[0083] cooling In the cooling step (S130), the molten glass composition is cooled to room temperature.

[0084] In this stage, the cooling is preferably performed in a furnace cooling manner. When air cooling or water cooling is applied, the internal stress of the composite glass may be excessively formed, and in some cases, cracks may occur, so the cooling is preferably performed in a furnace.

[0085] Crushing In the crushing step (S140), the cooled glass is crushed, preferably using a dry crusher.

[0086] By these grinding processes, the glass is finely ground to produce glass powder. These glass powders preferably have an average diameter of 30 μm or less, and more preferably, can exhibit an average diameter in the range of 15 to 25 μm.

[0087] Through the above steps (S110 to S140), an environmentally friendly glass powder for detergent according to an embodiment of the present invention can be manufactured.

[0088] When the environmentally friendly glass powder for detergent manufactured by the method according to the embodiment of the present invention is used as an environmentally friendly detergent, a new solution can be presented that realizes cleaning power equal to or superior to that of ordinary detergents.

[0089] Furthermore, when the glass powder for an environmentally friendly detergent manufactured by the method according to the embodiment of the present invention is used as an environmentally friendly detergent, since no surfactant is added, it is possible to shorten the rinsing process and reduce the amount of water used during washing.

[0090] In addition, when the environmentally friendly glass powder for detergent manufactured by the method according to the embodiment of the present invention is used as an environmentally friendly detergent, the washing efficiency can be increased when a normal detergent and elution water are used together, thereby resulting in an energy saving effect.

[0091] In addition, when the environmentally friendly detergent of the present invention is poured into the automatic detergent compartment of a washing machine, it can dissolve glass uniformly and consistently, thereby further extending the recurring period and maintaining high reliability even during repeated washing processes.

[0092] [Example] Hereinafter, the configuration and operation of the present invention will be described in more detail with reference to preferred embodiments of the present invention, which are presented as preferred examples of the present invention and are not to be construed as limiting the present invention in any sense.

[0093] Contents not described here will not be explained since those skilled in the art can easily deduce them from a technical standpoint.

[0094] 1. Preparation of samples and evaluation of cleaning power Table 1 shows the components and their ratios of the manufacturing examples for the borate-based glass composition. Table 2 shows the components and their ratios of the manufacturing examples for the silicate-based glass composition. Tables 1 and 2 also show the detergency of the detergents produced from each manufacturing example.

[0095] [Table 1]

[0096] [Table 2]

[0097] In this case, compositions 1 to 21 were mixed and stirred according to the compositions shown in Tables 1 and 2 to form glass compositions, and then the glass compositions were melted at a temperature of 1,050°C in an electric furnace, and then cooled to a glass bulk state by air cooling on a stainless steel plate to obtain cullet-shaped glass. The glass was then crushed in a dry crusher (ball mill) and passed through a 400 mesh sieve to produce an environmentally friendly glass powder sample for detergents with an average particle size of 20 μm in D90. Here, the raw materials for Na2O and K2O were Na2CO3 and K2CO3, respectively, and the other components were the same as those shown in Tables 1 and 2.

[0098] 2. Evaluation of cleaning power Tables 3 and 4 show the results of evaluation of the cleaning power of samples with each composition, and Table 5 shows the results of evaluation of the cleaning power of tap water and regular detergent. In Table 5, two types of regular liquid detergent (H Company's P product and L Company's T product) were used, which were added in fixed amounts and used as a reference to grasp the cleaning power level of glass elution water.

[0099] Here, the cleaning power was evaluated using a Terg-O-Tometer.

[0100] First, to prepare the elution water, 320 g of each glass powder prepared according to each composition was continuously immersed in a plastic container containing 600 mL of room temperature water, and 120 mL of the elution water was removed every 6 hours to evaluate the cleaning power, and 120 mL of tap water was filled into the plastic container to maintain 600 mL of water.

[0101] In this study, three types of soiled cloth were used: EMPA cloth with red wine and blood, and Jis cloth (composite soiled cloth), to study the cleaning power and cleaning durability of each composition of glass-dissolved water. The detergent power was evaluated according to the KS M 2709 standard.

[0102] Of the 600 mL of glass elution water, 120 mL was removed, 6 mL was added to 1 L of tap water, and the laundry was washed at 30°C for 10 minutes, followed by rinsing with 1 L of tap water for 3 minutes twice. For repeated cleaning power, 120 mL was removed from the 600 mL of elution water, 6 mL of the elution water was used for washing, and then 120 mL of tap water was added to the elution container, for a total of 40 washes for each composition. At this time, the time between the first wash test and the second wash was set to about 6 hours, allowing the elution water to be removed uniformly.

[0103] [Table 3]

[0104] [Table 4]

[0105] [Table 5]

[0106] As can be seen from Table 3, when the Al2O3 content in the borate composition is less than 5 wt%, the cleaning power is as high as that of a normal detergent. However, when the Al2O3 content is 5 wt% or more, the cleaning power for blood and jis contaminants is rapidly decreased. This is because the chemical durability of the glass composition increases and the elution property is rapidly decreased as the Al2O3 content increases.

[0107] It can also be seen that when the sum of the weight ratios of MgO and CaO exceeds 10% by weight, the cleaning power decreases. This is expected to be because durability increases when a large amount of alkaline earth oxides is added to the glass composition compared to alkali oxides.

[0108] In conclusion, in order for a borate composition to have a certain level of durability and cleaning power, the Al2O3 content must be 1 to 4 wt%, and the sum of the MgO and CaO contents should preferably be 1 to 10 wt%.

[0109] As can be seen from Table 4, in the case of the silicate composition, discoloration of wine-stained cloth occurred after washing. This was because the pH was increased to 11 or higher. It can be seen that when the SiO2 content in the silicate composition exceeds 70 wt%, the detergency rapidly decreases and becomes similar to that of tap water. This is because the elution characteristics are limited by the increased SiO2 content. Also, when the alkaline earth oxide content is 10 wt% or more, the detergency rapidly decreases, as can be seen from composition 21.

[0110] 3. Evaluation of cleaning durability FIG. 2 is a graph showing the cleaning durability of composition 3 (borate composition) and composition 14 (silicate composition).

[0111] As can be seen from FIG. 2, the cleaning power of the borate composition decreases from 30 times. This is because, during the dissolution process of the borate composition, the borate network breaks down with the dissolution of alkali and alkaline earth ions, which changes the composition and properties of the glass. On the other hand, it can be seen that the silicate composition exhibits almost constant cleaning power up to 45 times. Even when alkali and alkaline earth ions are dissolved, the silicate network of the silicate composition does not break down and its properties are maintained. In other words, it can be determined that the silicate composition produces porous glass as alkali and alkaline earth ions continue to dissolve.

[0112] In summary, borate glass has better cleaning power than silicate glass and does not cause discoloration of wine. However, it can be confirmed that silicate glass is even better than borate glass in terms of repeated cleaning power.

[0113] 4. Repeated washing test for composite composition system An example of a detergent glass composition having a composite composition system according to the present invention will now be described.

[0114] 3 and 4 show wash cycles of composite composition systems combining composition 3 and composition 14 at ratios of 9:1 (270 g:30 g), 8:2 (240 g:60 g), and 7:3 (210 g:90 g), respectively.

[0115] As can be seen from Figures 3 and 4, the combination of a borate composition with a silicate composition increases the number of washable cycles.

[0116] It can also be confirmed that even if the silicate composition is combined up to 20%, discoloration by wine does not occur. This is because B(OH)3 and B(OH)4 - This is the result of interactions between ions. However, when the ratio of the components is 7:3, it can be confirmed that the cleaning power for wine is even lower than that of regular detergents. Therefore, it can be said that the combination ratio of the components is 9:1 to 8:2 has the best cleaning power and also the best repeated cleaning power.

[0117] In this way, when 300g of the detergent composition using the glass composition is provided in a solid form as in the present invention, it can be used as an environmentally friendly detergent that can be used for more than 40 washes.Compared to existing environmentally friendly alkaline ionized water, the present invention has the advantage that it is highly usable and the volume of the product can be reduced because it is in a compact solid form rather than a liquid form.

[0118] In addition, the present invention does not cause discoloration of dye contaminants because it stably maintains the pH between 9.5 and 10.0, and since the present invention contains 5 wt% or more of CaO in the total composition, antibacterial properties can be exhibited inside the fabric and washing machine.

[0119] Table 6 shows the results of antibacterial evaluation of detergent compositions using the composite composition system of the present invention. It can be seen that antibacterial activity is exhibited in the case of the combination compositions between composition 3 and composition 14, and composition 4 and composition 12. On the other hand, it can be seen that the antibacterial activity of the composite composition system using composition 9, which has a high Al2O3 content, and composition 19, which has a high SiO2 content, drops sharply. This is because the contents of Al2O3 and SiO2 increase, and the Ca2 + This is because the elution of alkaline components is controlled.
