Description

Toilet bowl cleaning composition using oyster shell and its manufacturing method {A TOILET DETERGENT COMPOSITION USING OYSTER SHELL AND A METHOD FOR MANUFACTURING THE SAME}

The present invention relates to a toilet bowl cleaning composition using the oyster shell and a method of manufacturing the same.

Chlorine-based cleaners are strong oxidants, corrosive, cause irritation and damage to skin and eyes, release chlorine gas when mixed with acidic cleaners, and react with ammonia to generate nitrogentrichloride, which irritates mucosa.

In the case of multi-purpose cleaners, complex and excessive surfactants and synthetic odors for deodorizing purposes can adversely affect the human body in confined spaces such as toilets. In addition, since the cleaning of the toilet bowl and the manure bottle of the toilet and the toilet bowl, the lid and the toilet floor tiles are used separately at home, the substances produced by the random chemical reaction between them may be harmful to the human body.

In particular, the spray type cleaning agent may cause scattered liquid fine particles to enter the respiratory tract and cause health problems, and the toilet bowl detergent in powder form may be scattered arbitrarily and enter the respirator.

In order to prevent such side effects, products are being developed that utilize various shells and the like as compositions for antimicrobial purposes. However, in the case of the conventional cleaner using a shell, in order to increase the reaction speed and performance is processed in a powder form of a large surface area, there is a problem that the dispersibility in water and the fine powder is scattered arbitrarily by strong agglomeration between powder particles have.

In the pharmaceutical and food industries, most refined products are produced by wet granulation by granulating by adding a solution of powder to improve the flowability, formability and disintegration of the raw material mixture. However, the wet granulation method is limited to be applied to active ingredients sensitive to moisture and heat, and the fine powder generated excessively due to excessive drying decreases fluidity in the compression process and causes weight variation and peeling of the tablet.

On the other hand, when the active ingredient is sensitive to moisture or heat, dry granulation using a compression means such as a roller compactor is widely used. The dry granulation method does not use water or heat and can greatly improve the problems of the wet granulation method. In particular, in the case of the direct compression method, which is a type of dry granulation method, it is performed in a manner of mixing and compressing each component, so that there is an advantage of maintaining a unique function without changing any active ingredients.

The present invention is to solve the above-mentioned problems of the prior art, an object of the present invention is to provide a toilet cleaner and a method for manufacturing the toilet excellent in dispersibility in water, improved use and storage convenience, portability, hygiene will be.

One aspect of the invention, the calcium oxide particles obtained by firing and crushing the oyster shell; Dispersant particles; Blowing agent particles; And a disintegrant particle; is provided in a tablet form, provides a toilet bowl cleaning composition. Since the toilet cleaner composition is molded into a tablet form by pressurizing the powdery mixture, it is possible to drastically improve problems such as inconvenience in use and human hazards caused by random scattering of the conventional spray composition.

The calcium oxide particles are obtained by calcining and pulverizing the oyster shell under certain conditions, and are known to be excellent in sterilization and detergency, but because they are water insoluble, they have a problem of being settled in an aqueous solution and difficult to use as a toilet bowl cleaner. On the other hand, the dispersant particles not only relieve agglomeration and improve fluidity of the calcium oxide particles, but also disperse and soften the remaining or settled calcium carbonate after dissociation, causing clogging between or after use of the toilet bowl composition. Can be prevented.

The content of the calcium oxide particles may be 0.1 to 20% by weight, preferably 5 to 15% by weight based on the total weight of the toilet bowl cleaning composition. If the content of the calcium oxide particles is less than 0.1% by weight can be reduced cleaning power and bactericidal power, if it is more than 20% by weight dispersibility may be lowered.

The content of the dispersant particles may be 0.1 to 50% by weight, preferably 30 to 50% by weight based on the total weight of the toilet bowl cleaning composition. When the content of the dispersant particles is less than 0.1% by weight, the dispersibility and fluidity may be lowered, and when the content of the dispersant particles is more than 50% by weight, the cleaning and sterilizing power may be reduced.

The average particle diameter of the dispersant particles may be 10 ~ 100㎛.

In one embodiment, the blowing agent particles may include an inorganic carbonate and an acid. For example, the blowing agent particles may include the inorganic carbonate and the acid in a weight ratio of 1: 0.3 to 0.7, respectively. The inorganic carbonate may react with the acid to generate carbon dioxide, and the generated carbon dioxide may rapidly foam and disintegrate the detergent composition in water.

The content of the blowing agent particles may be 0.1 to 20% by weight, preferably 10 to 20% by weight, based on the total weight of the toilet bowl cleaning composition. When the content of the blowing agent particles is less than 0.1% by weight, the disintegration may be lowered, and when the content of the blowing agent is greater than 20% by weight, the cleaning and sterilizing power may be lowered.

In one embodiment, the inorganic carbonate may be one selected from the group consisting of sodium bicarbonate, potassium bicarbonate, calcium bicarbonate, sodium carbonate, potassium carbonate and a mixture of two or more thereof, preferably, sodium bicarbonate, but It is not limited.

In one embodiment, the acid may be one selected from the group consisting of citric acid, tartaric acid, phosphoric acid, acetic acid, maleic acid, fumaric acid, and mixtures of two or more thereof, preferably citric acid, but is not limited thereto. .

The average particle diameter of the inorganic carbonate and the acid may be 10 ~ 100㎛ and 10 ~ 500㎛, respectively, preferably, the average particle diameter of the acid may be 10 ~ 300㎛. By adjusting the average particle diameter of the said inorganic carbonate and the said acid in the said range, dry granulation can mutually be easy and foaming force can be improved.

In one embodiment, the disintegrant particles are starches, microcrystalline cellulose, crospovidome, low-substituted hydroxypropyl cellulose, croscarmellose, Croscarmellose), sodium starch glycolate (Sodium starch glycolate) and may be one selected from the group consisting of two or more thereof, preferably, may be starch (sugar starch) and starch glycolate, but is not limited thereto. It is not.
