Description

Toilet Bowl Cleaner Composition

The present invention relates to a toilet bowl cleaning composition, and more particularly, to a toilet bowl cleaning composition that can be used for cleaning the toilet, as well as preventing clogging of the toilet by waste pausing and manure and shortening the wastewater treatment time.

In the prior art, patents relating to a solid-type toilet bowl cleaning agent include British Patent Nos. 1601123, 2020143, and 2061996, all of which are the main cleaning components and solubility regulators for controlling their solubility. As regards those of the present invention, British Patent No. 2011143 is representative of 5 to 90 parts by weight of the main cleaning component, 0.5 to 75 parts by weight of the solubility regulator component, 0 to 20 parts by weight of the dye, 0 to 75 parts by weight of the fragrance, and other auxiliary materials. The additive is a sterilant, a metal ion encapsulant, an acid component, and the like, and is composed of 0 to 75 parts by weight.

The present invention relates to a composition in which an organic surfactant and a solubility control agent are added as essential ingredients, and other auxiliary agents are added. Here, the "organic surfactant" as the main cleaning component is an anionic, nonionic, cationic or zwitterionic interface. It refers to a mixture of an active agent and these surfactants, the term "solubility control agent" refers to a substance that serves to inhibit the rapid dissolving power of the organic surfactant as a hydrophobic substance or poorly soluble in water.

More specifically, the solubility control agent refers to clay or water-soluble or water dispersible gel-forming organic polymers such as laponite and bentonite, where "gel formation" refers to solubility control. When I dissolve or disperse in water to form a gel first and then elapse in water for a longer time, it becomes a free-flowing liquid and dissolves or disperses.

The present invention relates to a composition comprising the main cleaning component and the solubility regulator as an essential component, to which substances such as flavor, dye, fungicide, chlorine-based material, metal ion encapsulant, and acid are added.

The above composition is introduced into a water tank and settles to the bottom, and the water in the tank dissolves or disperses the exposed surface of the toilet cleaner to make this surface a layer of concentrated gel solution, and the water in the tank is in continuous contact with this layer. To slowly dissolve or disperse the solid. Therefore, when the water in the tank escapes, the gel layer concentrated by the water pressure and the vortex phenomenon is dispersed or dissolved to escape with the water to wash the toilet bowl. The tank is then filled with water up to the titration line to keep doing this.

In the present invention, the fibrinase system added to the conventional technology is physiological and biochemical characteristics of this enzyme system by many researchers since Reese et al. Reported fibrinase system in fibrinolytic microorganisms in 1950. And industrial applications have been conducted. As a result, it has been confirmed that the fibrinolytic enzyme system is produced by various microorganisms such as Trichoderma, Aspergillus, Cellulomonas, etc. The fibrinolytic enzyme system was found to be completely degraded by the coordination of components of at least endocellulase (CMCase), exocellulase (Avicelase) and glucosidase (β-glucosidase). lost.

Microbial fibrinase systems are also involved in the production of biofuels from abundant fibrous resources in nature, the production of simple cell proteins and feedstocks, and agricultural waste treatment. The industrial value is high.

On the other hand, enzymes in the natural state have several enzyme stabilization methods to solve the defects of these enzymes or proteins because their effects are enhanced or inhibited by chemical, physical and biological factors, and most of them are lost during storage or use. This invention, which has been studied, has stabilized soluble enzymes in aqueous solutions, stabilized by crosslinking or polymerizing enzyme molecules, binding enzymes to carriers, encapsulating enzymes in semipermeable membranes, and genetic engineering genetic modifications. In addition, there is a method of chemically converting the protein molecular structure using molecular biological protein engineering. Double solubilization of enzymes involves adding starch to fix alpha-amylase as a substrate stabilization and glucose to fix glucose amylase, and second to benzyl alcohol hydrolysis. Genase is unstable in high concentrations of acetone and ethanol, so it is stabilized in a solvent of 2% acetone and 10% ethanol. Third, Ca, Cu, Fe, Mn, Mo, and Zn are metallurgical enzymes (Metalloenzyme). The method of stabilization using salts, and the stabilization method by the addition of polymer polymers (gelatin, albumin, fatty acid, alcohol ethylene oxide, polyethylene glycol) and the method of binding enzyme to the soluble carrier. Formation of enzymes with amide bonds (eg production of polytyrosyl, polyglysyl enzymes) and acetyl, formyl, There is an acylation method to have a lopionyl and succinyl group.

As a method of stabilizing enzymes by immobilization, first, a crosslink is formed, and glutaraldehyde is used as a general polymer. Alpha amylase, chymotrypsin, ribonuclease, aminoacylase and the like are examples of polymerization by glutaraldehyde, and other crosslinking materials include hexamethylene diisocyanate. Second, the method of binding the enzyme to the carrier includes adsorption ion bonding, covalent bonding, etc., and is affected by the form of the structural binding site of the carrier, the ratio of the hydrophilic group to the hydrophobic group, the particle size, the surface area, and the volume ratio. Third, adsorption and desorption are free by binding by adsorption. Examples of the carrier include aluminum oxide, bentonite, glass, calcium phosphate gel, activated carbon, starch, tannin, aminohexyl cellulose, and the like. Fourth, cellulose derivatives are widely used as a representative carrier for forming microcapsules for microfiber polymers, and laundry detergent enzymes commercialized by NOVO are well known examples. Enzymatic detergents, diagnostic reagents and food additives are already examples of successful commercialization using these enzyme stabilization methods. Recently, Japanese Patent Laid-Open Nos. 63-240,785 Hei 2-435 and Hei 1-273,587 revealed that Endo-Cellulase of microorganisms is very efficient as a Laundry Detergent. There are no examples of use of toilet bowl cleaners outside the field of fire extinguishing agents.

Accordingly, in the present invention, the fibrinase system embedded in the clay or water dispersible gel (Gel) polymer is gradually eluted with the surfactant by mixing the fibrinase system with the existing toilet cleaner and solidifying the same enzyme reaction in the toilet bowl. This prevents the deposition of fibrous organic pigments, as well as fundamentally solves the blockage of the toilet outlet port caused by temporary retention of manure or waste paper (toilet paper), which is mostly fiber, and improves the purification efficiency in the septic tank. The purpose is to provide a toilet cleaner composition.

Hereinafter, the present invention will be described in detail.

The present invention provides a toilet bowl composition comprising a main wash component and a solubility regulator, wherein the toilet bowl comprises stably containing 30 to 50 wt% of the main wash component, 50 to 70 wt% of the solubility regulator and 100,000 to 100,000 units of the cellulase enzyme. Detergent composition.

Hereinafter, the present invention will be described in more detail.

Not only can it be achieved, but the effect is no longer increased. Stable use of fibrinolytic enzymes in conventional lavage cleaners used in water tanks (In tank or On tank) for toilet cleaning, on lavage (Rimblock), or in the form of liquid or powder By dissolving or dissociating toilet paper or manure residues in the toilet continuously as well as the purpose of cleaning the toilet, it is possible to increase the purification efficiency by decomposing fibrous manure residues in the septic tank as well as preventing clogging.

In the present invention, the analytical method used as a fibrinolytic activity-based unit was defined as separating and eluting 1 μmole of glucose from Cellulose at 37 ° C. and pH 6.7. It was measured according to the Somogy-Nelso method and converted to the standard curve of the reducing sugar calculated value.
