Description

Solid Auto Detergent Composition

The present invention relates to a solid automatic detergent composition for keeping the toilet of a flush toilet clean.

In general, self-cleaning toilets for flushing toilets are always kept in the water of the reservoir to prevent slime and scale from adhering to the wall of the toilet by water, and also to remove dirt when attached to the toilet and drain pipe during discharge. It is used for the purpose of doing so.

For this purpose, for example, Japanese Patent Publications No. 50-153011, No. 53-31708, No. 53-58507, No. 54-81310, No. 4,043,931, 4,119,578, 4,269,723, 4,438,015, Various cleaners such as 4,460,490 and 4,722,802 have been proposed.

In addition, representative products currently commercialized in Korea are polyoxyethylene nonyl phenolether (hereinafter referred to as NP) as a dispensing agent for washing, solidifying agent and dye, and urea as a filler and solidifying agent. Detergent in a glass jar or plastic container). However, these automatic cleaners use 80% by weight or more of components such as NP and urea, which are excellent in solubility in water, so they are excellent in solubility, but the products have a specific gravity of 1.1 to 1.2, which is heavier than water. If the container is not supplemented, the detergent solution is excessively eluted into the toilet bowl, and the period of use is short, and the cost of raw materials and subsidiary materials is not economical. There is a disadvantage that comes with environmental pollution.

Another type of self-cleaning agent, a complete solid without container, using polyoxyethylene glycol (hereinafter referred to as PEG) as a solidifying agent, dye, fragrance dispersion, and solubilizer, and adding a thickener and fungicide as necessary. This has been commercialized. It contains 80% by weight or more of PEG, which is a nonionic surfactant (a molecular weight of 4000 to 6000 is used in consideration of solubility and melting point in water), and contains a small amount of surfactants and thickeners other than PEG. Not only does the cleaning effect drop, but it is difficult to maintain the duration for a certain period of time (2 weeks (280 times or more)), and it is difficult to formulate the composition even if the composition elutes constantly in the reservoir.

In addition, PEG itself is only used as a solidifying, dispersing and solubilizing agent, so it is not preferable to use it because it has little washing ability and very low biodegradability by microorganisms in sewage, causing water pollution.

Accordingly, the object of the present invention is not only to solve the inconvenience of use and the economical problem of the container type automatic cleaning agent and the problem of disposal after use, but also to improve the short service life and the nonuniformity of the conventional non-type automatic solid cleaning agent. The present invention provides a non-carburizing solid autocleaner composition having a uniform elution of the composition without using a container and lasting up to 5 weeks or more.

In order to achieve the object of the present invention, the solid autocleaner composition of the present invention is a biodegradable PEG derivative, a mixture of etherified polysaccharides (hereinafter referred to as ESP), fatty acid ethanol emulsified with anionic surfactants. It consists of an amide, a surfactant having excellent detergency, a mixture of water and inorganic salts, a dye and a bactericide.

Hereinafter, the present invention will be described in detail.

The PEG derivative (hereinafter referred to as PE), which is a main component of the detergent of the present invention, is represented by the general formula I: R ₁ -O- (CH ₂ CH ₂ O) _n CH ₂ CH ₂ -OR ₂ (where n = 130). 220: R ₁ , R ₂ = C ₁₂ -C ₁₈ fatty acids), OH group of hydrophilic ethylene oxide is blocked and esterified both with lipophilic fatty acid, hydrophilic-lipophilic balance value (Hydro- Lipohilic Balace Value (hereinafter referred to as HLB value) is 10 to 20 and the fatty acid has a carbon number of 1 to 18, preferably 20 to 40% by weight based on the composition of the present invention. Fatty acid ethanol amide (hereinafter referred to as CEA) is a condensation product of low-soluble fatty acid and water-soluble ethanol amide. The higher the melting point, the lower the solubility and the higher the carbon number. It is preferable to use 5 to 20% by weight based on the composition of the present invention. CEA, which has a high melting point, does not maintain the cleanliness of the toilet due to floating matters when it is dissolved, and also forms a film on the product. Therefore, an emulsifier is used to emulsify and disperse it. Any one of anionic surfactants such as Olefinsulfonic Acid (hereinafter referred to as AOS), Alkylbenzene Sulfonic Acid (hereinafter referred to as LAS), Sodium Lauryl Sulfonic Acid (hereinafter referred to as SLS), etc. It is preferable to use 15% by weight, and in this case, it is preferable that the use ratio of the CEA and the anionic surfactant is 5: 1-1: 5 and the content ratio of the anionic surfactant is low.

Carboxymethyl cellulose (CMC) and hydroxy propyl methyl cellulose are used to prevent the solid detergent from escaping from the reservoir and to block the drain line of the reservoir and to keep the elution amount constant. Polymers such as (Hydroxy Propyl Methyl Cellulose, hereinafter referred to as HPMC) and etherified polysaccharide (hereinafter referred to as ESP) derivatives can be used as thickening, dispersion, and swelling agents. Therefore, in order to satisfy the thickening, dispersion, water welling and solubility at the same time, the use ratio of PE and thickener ESP is preferably 1: 5 to 5: 1, and it is particularly preferable to lower the amount of ESP used.

Inorganic salts used in the present invention can be used regardless of the type, as long as it is used in a conventional cleaning agent, especially calcium or magnesium salts are preferred, the ratio of the use of PE and inorganic salts is 9: 1 to 1: 9 It is preferable that the use ratio of salt is low.

In addition, the amount of ESP used as the thickener is preferably 5 to 20% by weight. The nonionic surfactants have different cleaning ability and degree of solidification according to their type and content. Such nonionic surfactants include nonionic surfactants obtained by addition polymerization of ethylene oxide or propylene oxide to higher alcohols. It is preferable to use, in this case, any of 12 to 18 carbon atoms of saturated, unsaturated, straight chain, branched can be used, and the addition mole number of ethylene oxide or propylene oxide is good from 10 to 50, especially the higher molar number of moles It is preferable to improve solidification and hardenability.

In addition, the composition of the present invention includes benzylthorium chloride (hereinafter referred to as BTC), alkali dimethylbenzyl ammonium chloride (hereinafter referred to as BAC), hexachlorophene (hereinafter referred to as HCP), and the like. A fungicide may be used, and the amount of the fungicide is preferably used in an amount of 0.1 to 0.5% by weight without affecting filthy water, and it is preferable to use quaternary ammonium which is easily decomposed to organic matter and has excellent biodegradability. In addition, the purity of the fungicide is 50% by weight or more, the higher the purity is more preferable.

In addition, a dye may be added to the composition of the present invention to maintain the cleanliness of the toilet after use, which may be used in any color such as blue, red, yellow, etc. It is preferred to add% by weight.

Comparative Example 1

5 wt% wax was added without adding PE and LAS, and 4 wt% ESP and 77 wt% LA were added in the same manner as in Example 1.

Comparative Example 2

It carried out similarly to the comparative example 1 except adding CEA as 5 weight% without adding PE and LAS.

As described above, the emulsification test of the CEA according to the combined use of PE and CEA of the present invention, the physical property test and the number of test results according to the content change have a slight difference in the solubility (number of times) depending on the content of PE and CEA. However, the use of 20 times / day at water temperature of 15 ℃ resulted in an improvement in the duration of about 560-600 times. The CEA coating and the suspended solids showed no CEA and SLS ratios of less than 5: 1 and the wax separated after stirring. . In addition, the unemulsified CEA formed a film of the product and the CMC generated suspended matters in the reservoir to maintain the cleanliness. When PE was more than 40% by weight, the solubility was almost unchanged.

In addition, when the Na ₂ SO ₄ content is more than 10% by weight, the product is hardened during the manufacturing process, and the particles are precipitated at 10% by weight, and similar to Na ₂ SO ₄ when CaCl ₂ is added. However, when the water content is 2.5 times higher than the CaCl ₂ content, such precipitation does not occur, but rather, the number of times of use is increased.

As described above, the solid automatic detergent composition of the present invention is not only easy to handle as described above, but also the elution rate is uniform and the frequency of use is remarkably increased without significantly affecting the water temperature change. It does not affect the microorganisms that sufficiently disinfect the soil while sterilizing sufficiently, and the composition, such as PE, dye, and the like, is a preferred detergent composition in a situation in which environmental problems are seriously raised because of high biodegradability.
