Description

Eco-friendly detergent composition and method for manufacturing eco-friendly detergent powder using same

The present invention relates to an eco-friendly detergent composition and a method for manufacturing an eco-friendly detergent powder using the same.

In general, a detergent refers to a mixture used to remove contaminants attached to the surface of an object by complex physical and chemical actions such as adsorption, wetting, lowering of interfacial tension, emulsification, solubilization, and dispersion. The use of detergents at home and abroad is on the rise.

These detergents have been developed steadily and are currently sold in various types, but among them, detergents with high cleaning power are widely used.

However, conventional detergents contain surfactants as main raw materials. These surfactants are difficult to decompose by microorganisms, which not only causes environmental pollution, but also acts as a factor to increase water consumption due to foam rinsing, and has a problem of causing skin damage due to contact with residual detergent or detergent.

Accordingly, although naturally-derived surfactants or detergents that do not contain surfactants have been developed, there is a disadvantage in that washing performance is inferior compared to conventional detergents.

Accordingly, there is a growing demand for an eco-friendly natural detergent composition that does not cause environmental pollution and exhibits a cleaning power comparable to that of an existing synthetic detergent.

Hereinafter, an eco-friendly detergent composition according to some embodiments of the present invention and a method for manufacturing an eco-friendly detergent powder using the same will be described.

The eco-friendly detergent composition according to an embodiment of the present invention has a cleaning power equal to or greater than that of a synthetic detergent to which a conventional petroleum-based surfactant is added while no surfactant is added.

In addition, the eco-friendly detergent composition according to an embodiment of the present invention has a cleaning power equal to or greater than that of a commercial detergent to which a bleaching agent is added without adding a bleaching agent.

In addition, the eco-friendly detergent composition according to an embodiment of the present invention does not contain a surfactant, so it has no skin toxicity, has excellent biodegradability, and can improve the water quality environment because rinsing water is saved during washing, while reducing the amount of water used. can contribute

As described above, the eco-friendly detergent composition according to an embodiment of the present invention does not contain a surfactant, which is a main component of an existing synthetic detergent.

In general, surfactants have very low biodegradability, so when they are discharged into rivers, they are difficult to be decomposed by microorganisms. In addition, since the synthetic detergent to which the surfactant is added generates a large amount of foam, a large amount of rinsing water is required for washing, thus acting as a factor to increase the amount of water used.

In contrast, the eco-friendly detergent composition according to an embodiment of the present invention has a washing performance equal to or higher than that of a synthetic detergent to which a surfactant is added, and does not cause water pollution because no surfactant is added, and significantly reduces the amount of water used. Not only that, there is no problem of skin damage caused by skin contact.

To this end, the eco-friendly detergent composition according to an embodiment of the present invention contains 35 to 90% by weight of a water-soluble glass composition, 1 to 35% by weight of sodium hydrogen carbonate, 1 to 10% by weight of sodium chloride, 1 to 25% by weight of an enzyme, 0.5 to 15% by weight of starch. % by weight, 0.5 to 15% by weight of wheat flour, and 0.5 to 5% by weight of polyvinyl alcohol.

Although the above-described eco-friendly detergent composition according to the embodiment of the present invention does not contain a surfactant, it exhibits an excellent cleaning power equal to or greater than that of a synthetic detergent to which a petroleum-based surfactant is added.

As a result, the eco-friendly detergent composition according to an embodiment of the present invention has excellent washing effect on dye-based contaminants, and does not reduce the washing power of protein contaminants due to the bleach, even though no bleach is added.

In addition, since the eco-friendly detergent composition according to the embodiment of the present invention does not contain a surfactant, it is possible to significantly reduce the amount of water used compared to synthetic detergents to which a petroleum-based surfactant is added, and only natural substances without a surfactant Since it is a used detergent, it is possible to prevent water pollution in advance.

In addition, the eco-friendly detergent composition according to an embodiment of the present invention can reduce the rinsing cycle of the washing machine, thereby exhibiting an energy reduction effect by reducing power consumption, and exhibiting superior deodorization properties compared to conventional synthetic detergents.

Hereinafter, the role and content of each component of the eco-friendly detergent composition according to an embodiment of the present invention will be described in detail.

water soluble glass composition

The water-soluble glass composition is a main component of the eco-friendly detergent composition, and serves to improve washing performance.

The water-soluble glass composition is preferably added in an amount of 35 to 90% by weight of the total weight of the eco-friendly detergent composition according to the present invention, and 40 to 80% by weight may be presented as a more preferable range.

When the water-soluble glass composition is added in an amount of less than 35% by weight, it is difficult to properly exhibit the effect of improving washing and bleaching performance by borate ions. Conversely, when the water-soluble glass composition exceeds 90% by weight, the washing power of pigments and proteins is improved, but there is a fear that the washing power of cocoa and proteins is reduced due to the relatively low enzyme content.

Here, it is preferable to use alkaline borosilicate glass as the water-soluble glass composition. More specifically, the alkaline borosilicate glass comprises 50 to 85% by weight of B ₂ O ₃ , 1 to 15% by weight of SiO ₂ , 5 to 50% by weight as a sum of Na ₂ O and K ₂ O.

Alkali borosilicate glass is a glass made by melting at high temperature based on mineral components (Na ⁺ , K ⁺ ) and borate component (BO) that can be easily found in nature. When low and added to water, a large amount of Na ⁺ , K ⁺ , OH ^- , B(OH) ₄ ^- ions are eluted. In particular, by increasing the elution of OH ^- ions, the pH of the wash water is raised to make it alkaline, thereby decomposing the pores in the fibers.

The eluted OH ^- ions and B(OH) ₄ ^- ions are particularly strong in the washing of proteins and lipids. Since approximately 70 to 80% of contamination occurring in daily life contains protein components, the cleaning performance of protein contamination can be said to be a very important comparison index for washing performance. The increase in the eluted OH ^- ions increases the pH and generally deviates from the protein isoelectric point formed by acid (pH4 ~ pH6), making the protein unstable, and the eluted ions decompose the protein to remove the contamination. Unlike the general removal of protein contamination according to an increase in pH, B(OH) ₄ ^- ions eluted from the glass also help remove protein contamination, thereby increasing washing performance.

Compared with general alkaline water, it can be seen that the protein cleaning power of alkaline borosilicate glass is superior even at the same pH.

In addition, one of the main characteristics of borate glass that affects washing is the role of a pH buffer (buffer). In the case of general alkaline borosilicate glass, when a large amount of alkali ions are eluted in water, OH ⁻ ions are formed in large amounts, so that the pH is increased to about 10 to 12 or more. In this case, discoloration of the pigment component, which is one of the stains that is difficult to clean, may occur and damage the fabric.

In general, a bleaching agent is added when washing with dye stains. On the other hand, in the case of borate glass, when eluted with water, not only alkali ions but also B(OH) ₃ , B(OH) ₄ etc. are formed, so that the pH is high to a certain level, that is, pH 9 to 10 or higher. do not support Accordingly, discoloration of the dye component does not occur and the fabric is not damaged.

In addition, B(OH) ₃ , B(OH) ₄ ⁻ ions in the glass have a bleaching performance, and thus have superior cleaning power against pigments compared to general detergents that do not contain a bleach of similar pH. Therefore, the eco-friendly detergent composition according to an embodiment of the present invention exhibits bleaching performance by borate ions even without adding separate bleaching agent components included in the existing detergent.

In general, bleach (oxidizing agent) is added for washing pigments as described above, and the reaction of the addition is to denaturate the protein locus, thereby reducing the cleaning performance of the protein locus.

On the other hand, it was confirmed that the eco-friendly detergent composition according to the embodiment of the present invention did not deteriorate the cleaning properties of the protein, unlike a general bleaching agent.

Table 1 shows odor substances that can be easily inhaled in daily life.

[Table 1]

As shown in Table 1, since the water-soluble glass composition elutes in water and exhibits an alkalinity of about pH 9 to 11, it easily decomposes acidic odor components.

Accordingly, the water-soluble glass composition of the present invention can be eluted in an aqueous solution to prepare various types of detergents from liquid or powder to tablet form.

In the water-soluble glass composition of the present invention, B ₂ O ₃ is a key component that enables sufficient vitrification as a glass former typically used together with SiO ₂ , P ₂ O ₅ , and the like, in the structure of the glass. It forms the core framework. B ₂ O ₃ is mainly in the form of BO ₃ , BO ₄ in the glass exists in the form of tri-coordinated and tetra-coordinated, and also serves to lower the melting temperature of the glass.

Compared to SiO ₂ glass, glass containing a lot of B ₂ O ₃ is vulnerable to water, maximizing the dissolution property of the glass. In addition, B ₂ O ₃ has a bleaching effect upon elution, and does not cause discoloration of dye contaminants because it acts as a pH buffer.

Accordingly, B ₂ O ₃ is preferably added in a content ratio of 50 to 85% by weight of the total weight of the water-soluble glass composition, and 65 to 80% by weight may be presented as a more preferable range. If the amount of B ₂ O ₃ added is less than 50% by weight, the bleaching effect may not be properly exhibited, and thus it may be difficult to secure cleaning power. Conversely, when the addition amount of B ₂ O ₃ exceeds 85% by weight, a decrease in water resistance may occur due to the nature of the element itself due to structural problems of B and P in the network-forming structure.

SiO ₂ is the most representative glass former oxide, and it is a component that needs to be added in a trace amount because it increases vitrification. If, when a large amount of SiO ₂ is added, it increases the water resistance of the glass and serves to control the elution. It also increases the melting temperature of the glass.

Accordingly, SiO ₂ is preferably added in a content ratio of 1 to 15% by weight of the total weight of the water-soluble glass composition, and 3 to 10% by weight may be presented as a more preferable range. When a large amount of SiO ₂ is added in excess of 15% by weight, there is a problem in that workability and yield are reduced in the cooling process as the viscosity increases when melting the glass. Conversely, when SiO ₂ is added in an amount of less than 1% by weight, the structure of the glass is weakened and there is a problem in that water resistance is lowered.

Na ₂ O and K ₂ O are alkali oxides, which are oxides serving as a network modifier for non-crosslinking in the glass composition. Na ₂ O and K ₂ O cannot be vitrified alone, but in a certain ratio with a glass former such as SiO ₂ , B ₂ O ₃ , P ₂ O ₅ , V ₂ O ₅ , Ga ₂ O ₃ Vitrification is possible by mixing with

Alkali ions are ion-exchanged with H ₃ O ⁺ and eluted in water to form OH ⁻ ions, so they are a major component of expression of detergency. However, when a large amount of alkali component is contained, the concentration of OH ⁻ ions increases, so that the pH increases to 10 to 11 or more, which causes discoloration of the pigment component.

Therefore, since the elution properties of the glass are very different depending on the content ratio of alkali oxide and B ₂ O ₃ , it can be said that controlling the content ratio is the core of the present invention. In the present invention, the initial dissolution characteristics are excellent, and even when continuously used, the dissolution is good.

Accordingly, Na ₂ O and K ₂ O are preferably added in a content ratio of 5 to 50% by weight based on the total weight of the water-soluble glass composition. When Na ₂ O and K ₂ O are added in an amount of less than 5% by weight as a sum, it may be difficult to secure washing durability. Conversely, when Na ₂ O and K ₂ O exceed 50 wt % in total, the concentration of OH ⁻ ions increases, which may cause discoloration of the pigment component.

Sodium bicarbonate (baking soda)

Sodium bicarbonate is one of the food additives commonly known as baking soda, which generates OH ^- ions to increase pH, penetrates deep into contaminants to improve cleaning power, as well as sterilizes and bleaches.

Such sodium bicarbonate is preferably added in a content ratio of 1 to 35% by weight of the total weight of the eco-friendly detergent composition according to the present invention. When sodium bicarbonate is added in an amount of less than 1% by weight, it may be difficult to properly exhibit a sterilizing action and a bleaching action. Conversely, when sodium bicarbonate is added in a large amount exceeding 35% by weight, the concentration of OH ⁻ ions may increase, thereby causing discoloration of the pigment component.

sodium chloride (salt)

Sodium chloride is a natural food that acts as an anti-corruption (preservative) detoxification, sterilization, odor removal, freezing prevention, and skin protection agent.

Sodium chloride is preferably added in a content ratio of 1 to 10% by weight of the total weight of the eco-friendly detergent composition according to the present invention, and may present 4 to 6% by weight as a more preferred range. When sodium chloride is added in an amount of less than 1% by weight, it may be difficult to properly function as an anti-caking agent. Conversely, when sodium chloride is added in a large amount in excess of 10% by weight, it is not economical because it may act as a factor increasing only the manufacturing cost without further increasing the effect.

enzyme

Enzymes are effective in removing oxidized stains such as immobilized proteins. One or more selected from the group consisting of protease, lipase, cellulase and amylase is added as the enzyme.

Table 2 summarizes the functions of each enzyme.

[Table 2]

As shown in Table 2, protease is effective in removing oxidized stains such as immobilized proteins, and lipase is effective in decomposing and removing fat components. In addition, amylase is effective in decomposing and removing starch-based components, and cellulase is effective in cleaning the fiber surface.

These enzymes are preferably added in a content ratio of 1 to 25% by weight of the total weight of the eco-friendly detergent composition according to the present invention, and as a more preferred range, 5 to 20% by weight may be presented. When the amount of enzyme added is less than 1% by weight, it may be difficult to remove oxidized stains such as immobilized proteins. Conversely, when the amount of enzyme added exceeds 25% by weight, the cleaning power of cocoa and proteins is improved, but there is a concern that the cleaning power of pigments and proteins is lowered due to the relatively low content of the water-soluble glass composition. have.

starch

Starch has a regular micelle structure by strong bonds between molecules. When water is added to such starch and heated, water molecules permeate into the micellar structure, and the distance between the starch particles gradually increases to expand, leading to gelatinization in which the micellar structure is disturbed. That is, the surface area that can come into contact with the contaminants increases due to the expansion of the starch, and the cleaning power of the detergent is improved. To this end, the starch is preferably added in a content ratio of 0.5 to 15% by weight of the total weight of the eco-friendly detergent composition according to the present invention.

flour

Flour is not a surfactant having both lipophilic and hydrophilic groups, but it has the ability to wash through adsorption due to its porous nature. In other words, since the starch and protein in the flour act as a lipophilic group, which is a kind of hydrocarbon substance, the adsorbed oil adheres well to the flour, so that more effective washing can be achieved.

To this end, the flour is preferably added in a content ratio of 0.5 to 15% by weight of the total weight of the eco-friendly detergent composition according to the present invention.

In particular, in the eco-friendly detergent composition according to an embodiment of the present invention, by using starch and flour at the same time, the contact area with contaminants, for example, oil scale, is increased by the expansion of starch, and oil is adsorbed by the porous nature of the flour. By doing so, the cleaning power can be significantly improved compared to the case of using only either flour or starch.

polyvinyl alcohol

Polyvinyl alcohol is a formulation that maintains the shape of the detergent and is added to change the state of glass, which has poor water resistance.

Polyvinyl alcohol is preferably added in a content ratio of 0.5 to 5% by weight of the total weight of the eco-friendly detergent composition according to the present invention. When polyvinyl alcohol is added in an amount of less than 0.5% by weight, it is difficult to properly function as a formulation agent because the amount added is too small. Conversely, when polyvinyl alcohol is added in excess of 5% by weight, it is not economical because it may act as a factor increasing only the manufacturing cost without any further effect.

Hereinafter, a method for manufacturing an eco-friendly detergent powder according to an embodiment of the present invention will be described with reference to the accompanying drawings.

As shown in Figure 1, the environmentally friendly detergent powder manufacturing method 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).

mix

In the mixing step (S110), 35 to 90% by weight of a water-soluble glass composition, 1 to 20% by weight of sodium hydrogen carbonate, 1 to 10% by weight of sodium chloride, 1 to 10% by weight of an enzyme, 0.5 to 15% by weight of starch, 0.5 to 15% by weight of wheat flour % and 0.5 to 5% by weight of polyvinyl alcohol and stirred to form a detergent composition.

melt

In the melting step (S120), the detergent composition is melted.

In this step, the melting is preferably carried out at 900 ~ 1,400 ℃ for 1 ~ 60 minutes. When the melting temperature is less than 900° C. or the melting time is less than 1 minute, the water-soluble glass composition cannot be completely melted, thereby causing an immiscibility of the glass melt. Conversely, when the melting temperature exceeds 1,400° C. or the melting time exceeds 60 minutes, it is not economical because excessive energy and time are required.

Cooling

In the cooling step (S130), the molten detergent composition is cooled to room temperature.

In this step, the cooling is preferably performed in a cooling in furnace method. When air cooling or water cooling is applied, internal stress is severely formed and cracks may occur in some cases, so furnace cooling is preferable.

smash

In the pulverization step (S140), the cooled detergent solids are pulverized. In this case, the pulverization is preferably performed using a dry pulverizer.

By this pulverization, the detergent solid is finely pulverized to produce an eco-friendly detergent powder. The eco-friendly detergent powder may have an average diameter of 30 μm or less, but is not limited thereto.

As described above, the method for manufacturing an eco-friendly detergent powder according to an embodiment of the present invention may be completed.

실시예Example

Hereinafter, the configuration and operation of the present invention will be described in more detail through preferred embodiments of the present invention. However, this is presented as a preferred example of the present invention and cannot be construed as limiting the present invention in any sense.

Content not described here will be omitted because it can be technically inferred sufficiently by a person skilled in the art.

1. 친환경 세제 분말 시료 제조1. Preparation of eco-friendly detergent powder samples

Table 3 shows the components and their component ratios for the eco-friendly detergent composition according to Examples 1 to 5. At this time, the eco-friendly detergent composition having the composition shown in Table 3 was melted at a temperature of 1,000° C. in an electric furnace, and then cooled in a glass bulk form by an air cooling method on a stainless steel sheet to obtain a detergent solid in the form of a cullet. Thereafter, the detergent solid was pulverized with a dry grinder (ball mill), and then passed through a 400 mesh sieve to prepare an eco-friendly detergent powder. Here, as the water-soluble glass composition, 70 wt% of B ₂ O ₃ , 8 wt% of SiO ₂ , 10 wt% of Na ₂ O, and 12 wt% of K ₂ O were used.

[Table 3] (Unit: wt%)

2. 세척력 측정2. Measurement of cleaning power

Table 4 shows the cleaning power measurement results for the samples according to Examples 1 to 5 and Comparative Examples 1 to 3. Here, samples according to Comparative Examples 1 to 3 were obtained using three commercially available commercial detergents.

[Table 4]

As shown in Tables 3 and 4, as a result of measuring the cleaning power, the samples prepared according to Examples 1 to 5 exhibited an equivalent level of cleaning power compared to commercial detergents, in particular, despite the fact that no surfactant was added. In the case of the sample prepared according to 1, it showed superiority in cleaning power compared to commercial detergents.

As such, in the case of the eco-friendly detergent powder samples prepared according to Examples 1 to 5, it can be seen that the washing power of specific ogu increases or decreases according to each component and their component ratio. That is, when the content of alkaline borosilicate glass is high, the cleaning power of pigments (wine) and proteins (blood) is improved, and when the content of the enzyme is high, the cleaning power of cocoa and proteins is improved. .

Based on the above experimental results, in the case of eco-friendly detergent powder samples, by controlling each component and their ratio, it was proved that it is possible to develop a detergent specialized for a specific Ogu.

3. 피부자극 및 독성 테스트 3. Skin irritation and toxicity test

As shown in Fig. 2, for the skin irritation test on the eco-friendly detergent powder sample prepared according to Example 1, a third-party accredited certification institution (Korea Testing & Research Institute) was requested, and the result of the request was negative in the skin irritation test result. You can confirm that you have been judged.

In addition, in order to evaluate the toxicity of the eco-friendly detergent powder sample prepared according to Example 2, the oral acute toxicity evaluation and the fish acute toxicity test (ETF-20057) were evaluated at the Korea Biosafety Research Institute.

At this time, oral acute toxicity evaluation is a test of administering a certain amount of detergent to rabbits for 14 days, and it received GHS classification 5 (lowest toxicity), and the fish acute toxicity test evaluates the toxicity of detergent for killifish, the lowest toxicity was assessed.

Based on the above experimental results, it can be determined that the eco-friendly detergent of the present invention is low toxicity.

As described above, the present invention has been described with reference to the illustrated drawings, but the present invention is not limited by the embodiments and drawings disclosed in the present specification. It is obvious that variations can be made. In addition, although the effects according to the configuration of the present invention have not been explicitly described and described while describing the embodiments of the present invention, it is natural that the effects predictable by the configuration should also be recognized.
