Description

TECHNICAL FIELD [0001] The present invention relates to an eco-friendly detergent composition,

The present invention relates to an environmentally friendly detergent composition and a method of manufacturing the same. More particularly, the present invention relates to an environmentally friendly detergent composition capable of realizing excellent detergency and odor removing effect while excluding the use of harmful substances such as hydrochloric acid, phosphoric acid and volatile aromatic compounds (VACs) And a method for producing the same.

Generally, there is a large amount of microorganisms such as germs and harmful pollutants harmful to hygiene in a bathroom or a bathroom, so it is necessary to maintain a sanitary condition by using a detergent that exhibits effects such as sterilization, bleaching, and odor removal.

In the prior art, products using lactic acid (HCl) as a main component (lactose, etc.), which is one kind of strong acid, were mainly used in consideration of disinfection and bactericidal action of microorganisms. However, hydrochloric acid has a sterilization action based on strong oxidative power and thus disinfection effect, but it causes not only strong corrosion but also contact with skin in use, resulting in dermatitis and odor.

In addition, the existing toilet or bathroom exclusive cleaning agent has a problem in that when it is diluted with hard water, a white precipitate is formed. Therefore, there is a problem that water quality is limited for dilution, such as formation of unevenness after use or precipitation remains and deterioration of cleaning effect remarkably . In addition, according to the standard used in the Industrial Safety and Health Law, phosphoric acid and hydrochloric acid should be contained in less than 1%, respectively. However, there were many cases where the cleaning agent using the conventional hydrochloric acid as the main component was not free from such criteria.

To solve this problem, various kinds of compounds such as surfactant, polyether polyol, cellulose sodium salt, octadecyltrimethoxysilane and the like are mixed at a specific ratio together with hydrochloric acid and phosphoric acid, There has been developed a composition which does not cause sediment and stains, has excellent cleaning power against stains and has a suppressed corrosion power against the base material. However, as a result of reducing the content of hydrochloric acid and phosphoric acid to reduce a number of side effects, there has been a problem of insufficient sterilization effect for use in bathrooms and toilets.

Especially, the public toilets or public toilets installed in the outdoors are known to breed more than 30 kinds of bacteria more than ordinary household toilets. Eight of them are 'opportunities' Since the detergent for use in such a space must have a better detergency, the above-described deterioration of the germicidal effect has been a cause of decreasing the utility as a detergent.

On the other hand, when treating a manure in a portable toilet or a public toilet through a detergent, there is a problem of stench generation due to a long time of neglect and a large storage space in order to ferment a large amount of minerals. In the case of manure, A complicated purification process for disposal requires a great deal of cost and effort, and it is difficult to completely purify it, causing problems such as soil contamination and pest generation.

Recently, in the field of cleaning agents, the demand for environmentally friendly products has increased, and the development of eco-friendly products has been actively carried out. In order to obtain environmentally friendly certification, human harmful substances such as hydrochloric acid and phosphoric acid and corrosive substances should not be used. In addition, volatile aromatic compounds (VACs) such as benzene, toluene, ethylbenzene, xylene, styrene and 1,4- There are a number of stringent criteria, such as the pH of the detergent composition must be within the range of 2 to 11 while excluding use.

Accordingly, there is a need to develop an environmentally friendly detergent which can reduce the use of hydrochloric acid, phosphoric acid, and harmful substances to solve the problem of human harm or corrosion while providing superior detergency and solving the problem of odor generation through comparatively easy usage. to be.

Eco-friendly detergent composition

According to one embodiment of the present invention, the environmentally friendly detergent composition comprises 2 to 4 parts by weight of citric acid; 0.05 to 1.5 parts by weight of sodium citrate dihydrate (Trisodium citrate dihydrate); 0.5 to 3.5 parts by weight of a nonionic surfactant; From 2.5 to 5 parts by weight of an anionic surfactant, 0.01 to 0.3 parts by weight of a fat soluble fragrance; And 0.001 to 0.5 parts by weight of a coloring matter. Further, it may further include 88 to 93 parts by weight of a solvent.

The solvent is a substance for dissolving a water-soluble substance, and generally used water, specifically, purified water, distilled water, and the like, but is not limited thereto. The solvent is used to provide the detergent composition in liquid form, and its content may be 88 to 93 parts by weight, preferably 90 parts by weight. If the amount of the solvent is less than 88 parts by weight, problems may arise in improving the viscosity in forming the liquid composition. If the amount is more than 93 parts by weight, the concentration of the solute may be lowered and the cleaning effect may be lowered.

On the other hand, the detergent composition may contain eco-friendly substances such as citric acid and trisodium citrate dihydrate as a material for replacing harmful components such as hydrochloric acid, phosphoric acid, have. In particular, citric acid can perform the function of lowering the overall pH of the composition, and thus the composition exhibiting acidity can be applied for bathing or toilet cleaning. That is, the present invention is not limited thereto, but in some embodiments the detergent composition may be free of hydrochloric acid and phosphoric acid.

The total pH of the detergent composition according to the addition of citric acid may be 2.5 to 3.5, preferably 3.0, but is not limited thereto. Depending on the use of the detergent, the content of citric acid may be varied or other basic compounds may be applied The pH can be adjusted to be in the range of 2-11.

The citric acid usually exists in the form of powder, and may be diluted with a solvent if necessary. Citric acid may exhibit a sterilizing function in addition to the above-described pH control function, and may be mixed in an amount of 2 to 4 parts by weight, preferably 3 parts by weight, in order to exhibit such a function. If the content of citric acid is less than 2 parts by weight or more than 4 parts by weight, the pH of the detergent composition may be out of the range of 2.5 to 3.5, which may be difficult to apply to bathrooms or toilets.

When the citric acid is used alone, the detergency may be insignificant. In addition, the effect of deodorizing power, sterilizing power, cleaning power, etc. can be improved by adding sodium citrate dihydrate. The sodium citrate dihydrate may also be provided in the form of powder like citric acid, but may be applied in a liquid form diluted with a solvent or the like if necessary.

The content of the sodium citrate dihydrate may be 0.05 to 1.5 parts by weight, preferably 0.5 to 1 part by weight, more preferably 0.7 part by weight, which is relatively lower than citric acid. If the content of the sodium citrate dihydrate is less than 0.05 parts by weight, sufficient deodorizing power, disinfecting power, and detergency can not be imparted to the detergent composition. If the amount is more than 1.5 parts by weight, the turbidity of the detergent composition may increase, resulting in inconvenience in use.

The citric acid and sodium citrate dihydrate may inhibit the generation of stones that may occur in the toilet, thereby preventing the offensive odor caused by ammonia gas or the like, which may be generated incidentally therefrom.

Among the components that impart detergency, deodorizing power, etc. to the detergent composition, a mixture of a nonionic surfactant and an anionic surfactant may be used as the surfactant. The content of the nonionic surfactant may be 0.5 to 3.5 parts by weight. When the content of the nonionic surfactant is less than 0.5 parts by weight, the effect of detergency or deodorization power may not be realized sufficiently. If the content of the nonionic surfactant is more than 3.5 parts by weight, miscibility may be lowered.

The nonionic surfactant may comprise a first surfactant and a second surfactant that are different from each other. Compared with the use of the first surfactant or the second surfactant alone, the effects such as washing power, deodorizing ability and biodegradability can be improved when they are mixed in an appropriate ratio.

In an exemplary embodiment, the first surfactant may comprise polyoxyethylene tridecyl ether and / or polyoxyethylene lauryl ether. Also, the second surfactant may be an α-phosphono-ω- (methylphenoxy) poly (oxy-1,2-ethanediyl) dipotassium salt (α-phosphono-ω- , 2-ethanediyl), dipotassium salt). Polyoxyethylene tridecyl ether, polyoxyethylene lauryl ether and? -Phosphino-? - (methylphenoxy) poly (oxy-1,2-ethanediyl) dipotassium The salt is excellent in compatibility with the citric acid solution and the sodium citrate dihydrate solution, especially the sodium citrate dihydrate solution, so that the productivity can be improved by reducing the foaming during the manufacturing process.

Also, the first surfactant and the second surfactant may be mixed in a weight ratio of about 1: 0.4 to 1: 0.6, or a weight ratio of about 1: 0.5. If the content ratio of the second surfactant is less than 0.4 or more than 0.6 based on the relative content ratio of the first surfactant, the synergistic effect due to the mixing use of the surfactant may not be exhibited. Also, the mixing property may be deteriorated. As a non-limiting example, 0.5 to 1.8 parts by weight of the first surfactant and 0.03 to 1.5 parts by weight of the second surfactant may be contained in 2 to 4 parts by weight of citric acid.

The first surfactant and the second surfactant may each have a biodegradability of 90% or more, preferably 95% or more, with respect to an organic material. When the biodegradability of the surfactant is high, soil contamination due to the discharge of organic matter such as manure can be prevented, and thus it can exhibit excellent efficacy as an environmentally friendly detergent composition.

In addition, the detergent composition may include a first surfactant, which is a nonionic surfactant, and a third surfactant, which is an anionic surfactant, in addition to the second surfactant. The third surfactant shows a polarity different from that of the first surfactant and the second surfactant. By mixing them in an appropriate ratio, it is possible to exhibit a more excellent synergistic effect in improving detergency, deodorizing power, and biodegradability.

The total amount of the nonionic surfactant is 0.5 to 3.5 parts by weight, the content of the anionic surfactant may be 2.5 to 5 parts by weight, preferably 3 to 4 parts by weight, more preferably 3.5 parts by weight. If the content of the nonionic surfactant is less than 2.5 parts by weight or exceeds 5 parts by weight, the synergistic effect due to the mixed use of the surfactant may not be realized or the use may be inconvenient due to increased turbidity. For example, the content of the anionic surfactant may be greater than the sum of the contents of the first nonionic surfactant and the second nonionic surfactant.

The anionic surfactant may include sodium lauryl ether sulfate. Sodium lauryl ether sulfate can be improved in productivity by reducing the occurrence of bubbles during the manufacturing process because of excellent compatibility with citric acid solution and sodium citrate dihydrate solution, especially sodium citrate dihydrate solution.

As with the first surfactant and the second surfactant, the third surfactant may have a biodegradability of at least 90%, preferably at least 95%. The effect of using a surfactant having a high degree of biodegradability is as described above.

The mixing of the first surfactant, the second surfactant, and the third surfactant can improve the miscibility of the composition as a whole. In addition to the water-soluble fragrance having high volatility as a fragrant ingredient, the oil-soluble fragrance such as high- May be used.

Specifically, the perfume may be one or more essential oils selected from the group consisting of Linalool, Geraniol, and Terpineol, but is not limited thereto. But can be used regardless of the kind of the oil-soluble high-quality essential oil which can highlight the environment-friendliness with the original aroma of the natural substance.

The content of the fragrance may be 0.01 to 0.3 parts by weight, preferably 0.15 to 0.25 parts by weight, more preferably 0.2 parts by weight. If the content of the perfume is less than 0.01 part by weight or more than 0.3 part by weight, the effect of the addition of the perfume is insignificant or too strong, which may cause a feeling of discomfort when used.

The detergent composition may contain a coloring matter for the purpose of improving the appearance of the eyes and the like. As the kind of pigment, various kinds of red, blue and yellow colors can be used. 68921-42-6 pigment may be used, but is not limited thereto.

The detergent composition in which the above-described components are mixed in a specific ratio can be environmentally friendly and excellent in cleaning power by replacing conventional hydrochloric acid and phosphoric acid by using a citric acid compound to inhibit the occurrence of corrosion. Examples thereof include benzene, toluene, ethylbenzene, (VACs) such as styrene, 1,4-dichlorobenzene, and the like can be eliminated, thereby reducing the damage caused by harmful substances to human bodies.

Method for producing environmentally friendly detergent composition

1 is a flowchart illustrating a method of manufacturing an environmentally friendly detergent composition according to an embodiment of the present invention.

Referring to FIG. 1, a method for preparing an environmentally friendly detergent composition according to an embodiment of the present invention comprises mixing and stirring (S100) a solvent and 2 to 4 parts by weight of citric acid (S100), adding a citric acid citrate (S300), mixing and stirring (S400) of 0.05-3.5 parts by weight of a nonionic surfactant and 0.01-0.3 parts by weight of a perfume, , Adding and stirring (S500) 2.5 to 5 parts by weight of an anionic surfactant, and adding and stirring (S600) 0.001 to 0.5 parts by weight of a coloring agent.

The step (S100) of dissolving citric acid and the step (S200) of adding and stirring the sodium citrate dihydrate are steps of dissolving citric acid and sodium citrate dihydrate before dissolving the surfactant in a solvent, The dissolution may improve the miscibility of the surfactant. That is, when the surfactant is dissolved in the solvent before the addition of the citric acid compound, the detergent composition may cause turbidity or deteriorate the physical properties of the detergent composition due to miscibility, have.

In this case, the stirring time of the step (S200) of stirring the sodium citrate dihydrate may be 1.5 times or more the stirring time of the step (S100) in which citric acid is dissolved and stirred. For example, when the stirring time of the step (S100) for dissolving citric acid in the solvent is 10 minutes, the stirring time of the step (S200) of dissolving the sodium citrate dihydrate may be 15 minutes or more. If the stirring time of the sodium citrate dihydrate is less than 1.5 times the stirring time of citric acid, the powder may precipitate in the detergent composition and the overall quality may be deteriorated.

The content of each of the solvent, citric acid and sodium citrate dihydrate and the effect of the control thereof are as described above.

The step S300 of mixing and stirring the non-ionic surfactant with the oil-soluble fragrance may mix the nonionic surfactant and the fragrance through a separate process from the above-mentioned process steps. That is, the nonionic surfactant and the oil-soluble fragrance can be uniformly mixed in a separate stirrer. For example, when the step (S100, S200) of mixing citric acid and sodium citrate dihydrate with stirring is carried out in the first stirring tank, the step S300 of mixing and stirring the nonionic surfactant and the fat-soluble flavoring agent is performed in the second stirring tank So that both steps can be performed independently.

The nonionic surfactant may be a mixture of the first surfactant and the second surfactant in a weight ratio of 1: 0.4 to 1: 0.6. The effect of the kind of the surfactant and the content ratio of the surfactant is as described above. The overall content of the nonionic surfactant and the perfume and the effect thereof are also as described above.

The non-ionic surfactant may exhibit good miscibility with fragrances, preferably liposoluble fragrance, so that it may be desirable to mix both materials in the same step. That is, when the citric acid compound is directly added to the first stirring tank where the nonionic surfactant (the first surfactant and the second surfactant) and the flavoring agent are not dissolved separately, the citric acid compound is mixed and stirred, Or physical properties such as detergency and deodorizing power of the detergent composition may be deteriorated.

Subsequently, a mixture of citric acid and sodium citrate dihydrate mixed in the first stirring tank and a mixture of nonionic surfactant and fat-soluble flavoring agent are mixed and stirred (S400). As described above, a nonionic surfactant having relatively low miscibility with citric acid and sodium citrate dihydrate and a fat-soluble flavoring agent are mixed and dissolved in a separate stirrer and then added to the mixture in which the citric acid compound is dissolved to maximize their miscibility .

Then, an anionic surfactant is added and stirred (S500). At this time, the anionic surfactant may be a third surfactant, and the specific content and the effect thereof are as described above. The inventors have discovered the problem of turbidity in the detergent composition when an anionic surfactant is added, for example, with a fat soluble flavor. Therefore, it is preferable that the anionic surfactant is added to the first stirring tank into which the citric acid compound is added, later than the fat-soluble flavor.

Also, the liposoluble dyes and the fragrances described later are relatively high in viscosity. Therefore, it is possible to improve the miscibility by introducing the anionic surfactant later than the fat-soluble flavor and injecting it before the flavor. That is, the step (S500) of adding the anionic surfactant may be performed before the step (S300, S400) of adding and mixing the nonionic surfactant and the fat-soluble flavor, or the step (S600) If it is carried out late, there may occur a problem of turbidity and deterioration of physical properties due to reduction of miscibility.

Then, when the addition and agitation of the anionic surfactant are completed, pigments may be added and mixed to impart a desired color to the composition (S600). As described above, the dye has a high viscosity and is preferably added later than the anionic surfactant. When the time of application is changed, miscibility may be reduced as with other materials. The kind and content of the pigment are as described above.

The method for preparing an environmentally friendly detergent composition according to the present embodiment can produce an environmentally friendly detergent while controlling the content of each compound within a certain range and specifying the order of introduction of these compounds, thereby achieving excellent detergency. On the other hand, when any one of the above-mentioned conditions is changed, problems such as turbidity may occur together with deterioration of detergency, deodorizing ability, biodegradability, and the like.

Referring to the above Table 3, all of the detergent compositions of Production Examples 1 to 5, in which all of the four surfactants were used, were found to have a high microbial killing rate of 95% or more, while the four kinds of surfactants , Or the detergent compositions of Comparative Examples 1 to 7, in which the content is out of the specified range, show a mortality rate of less than 80%.

Experimental Example 2: Measurement of deodorizing ability according to kind and content of surfactant

In order to compare the effect of removing the odorous gas from the detergent compositions according to Production Examples 1 to 5 and Comparative Examples 1 to 7, the gas concentration was measured before application of each composition and after 24 hours from application using a detection tube Then, the deodorization rate (%) was calculated using the following equation (1).

[Equation 1]

At this time, the malodorous gas to be measured is set to four kinds of representative gases generated in a typical residential space: ammonia, trimethylamine, methylmercaptan, and hydrogen sulfide. Standard concentrations of ammonia 120 ppm, trimethylamine 60 ppm, 20 ppm of methyl mercaptan, and 79 ppm of hydrogen sulfide. The results of each measurement are shown in Table 4 below.

With reference to Table 4, it can be seen that the detergent compositions of Production Examples 1 to 5, in terms of the deodorization rate against four types of odorous gases, are superior to the compositions of Comparative Examples 1 to 7 in which any one or more of the surfactants is omitted, It can be confirmed that the effect is superior to the conventional method.

Experimental Example 3: Measurement of biodegradability according to kind and content of surfactant

In order to measure the biodegradation effect of the detergent composition according to Production Examples 1 to 5 and Comparative Examples 1 to 7, manure was collected from a manure decay bath and diluted to make a chemical oxygen demand (COD) of 1,000 ppm The biodegradability of the supernatant was measured by an average amount of chemical oxygen demand in the supernatant after the incubation at 25 ° C for 1 hour and the incubation for 7 hours to 8 days. The results are shown in Table 5 below.
