Method for manufacturing Washing tablet

The present invention relates to a tablet for washing and a method for manufacturing the same, and more particularly, it is coated with a film that dissolves in water so that it is not easily decomposed due to its excellent moisture-blocking ability when stored, and also dissolves easily in washing water and dissolves and foams at the same time The present invention relates to a tablet for washing improved so as to be able to obtain a bubble washing effect by strongly generating acid, and to prevent environmental pollution due to eco-friendly ingredients, and a method for manufacturing the same.

In general, a detergent used for washing is a substance added when washing the fabric to help the washing of the fabric. Laundry detergents are mainly used in powder or granular form, and liquid detergents are also on the market recently.

Conventional most detergents, regardless of powder, granule, or liquid, increase the content of the foaming agent to increase the foaming in order to increase the cleaning power.

In particular, since synthetic surfactants such as sodium lauryl sulfate or sodium laureth sulfate are used as surfactants to increase cleaning power, water pollution is caused, and when fibers washed with such detergents are worn, they come into contact with the skin. It has the disadvantage of being harmful to the human body, such as promoting skin aging by destroying the sebum and stratum corneum and causing various skin diseases.

In order to improve this, a solid laundry detergent in the form of an egg (tablet) concentrated using active protease and ingredients having an oxygen-based bleaching function completely harmless to the human body has been disclosed.

However, these solid laundry detergents are compact and highly concentrated tablets, so they are convenient to use and eco-friendly because they contain almost no chemical components. Therefore, care is required and there is a disadvantage that the washing ability is somewhat lowered due to the lack of foaming properties.

Republic of Korea Patent Registration No. 10-1753371 (June 27, 2017), 'Hydrogen Washing Tablet' Republic of Korea Patent Publication No. 10-2012-0136853 (2012.12.20), 'Eco-washing tablet cleaner and manufacturing method thereof'

The present invention was created to solve the problems in the prior art as described above, and it is coated with a film that dissolves in water, so it has excellent moisture blocking ability when stored, so it is not easily decomposed, and it is easily dissolved in washing water during washing. Its main purpose is to provide an improved tablet for washing and a method for manufacturing the same, so that it is possible to obtain a bubble washing effect by strongly generating foaming properties at the same time as it is released, and to prevent environmental pollution due to eco-friendly ingredients.

The present invention is a means for achieving the above object, based on 100 parts by weight of hydrogen ion water, sodium bicarbonate 60 parts by weight, citric acid 30 parts by weight, corn starch 5 parts by weight, cocamidopropyl betaine 5 parts by weight, SLSA (Sodium Lauryl Sulfoacetate) 10 parts by weight, pancreatin (Pancreatin) 5 parts by weight, lipase (Lipase) 5 parts by weight, aluminosilicate 10 parts by weight and sodium metasilicate 15 parts by weight of the tablet composition comprising a tablet composition and compressed tablet; It provides a tablet for washing, characterized in that consisting of; a film soluble in water coated on the surface of the compressed tablet tablet.

According to the present invention, it is coated with a film that dissolves in water so that it is not easily decomposed due to its excellent moisture barrier ability during storage, and it dissolves easily in washing water during washing, and at the same time it is easily released and strong foaming property can be obtained to obtain a bubble washing effect, An improved effect can be obtained to prevent environmental pollution due to eco-friendly ingredients.

Hereinafter, preferred embodiments according to the present invention will be described in more detail.

Since the embodiment according to the concept of the present invention may have various changes and may have various forms, it should be understood to include all modifications, equivalents, and substitutes included in the spirit and scope of the present invention.

The laundry tablet according to the present invention is also formed in the form of a tablet formulation, that is, an egg (tablet) as in the prior art.

However, unlike the conventional method that maintained only the formability, it is characterized in that it has a structure in which the outer surface is coated with a film so that it does not melt and crumble even when it comes into contact with moisture when stored in the form of a pill while maintaining the formability.

In particular, it is formulated to cause strong foam as the film melts when in contact with washing water. In other words, the film melts and dissolves only when it is continuously in contact with a certain amount of moisture (water) for a certain period of time or more, and it does not melt and dissolve when it encounters a small amount of moisture while it is being stored as a pill. However, in the conventional case, there was a disadvantage in that the formability (that is, the pill form collapses) is lost because it is sensitive to even a small amount of moisture and a part is easily melted and released.

More specifically, the laundry tablet according to the present invention contains 60 parts by weight of sodium bicarbonate, 30 parts by weight of citric acid, 5 parts by weight of cornstarch, 5 parts by weight of cocamidopropyl betaine, and sodium lauryl (SLSA) based on 100 parts by weight of hydrogen ionized water. Sulfoacetate) 10 parts by weight, pancreatin (Pancreatin) 5 parts by weight, lipase (Lipase) 5 parts by weight, aluminosilicate 10 parts by weight and sodium metasilicate 15 parts by weight of a compressed dosage form tablet prepared from a tablet composition comprising; It is composed of a water-soluble film coated on the surface of the compressed-formulation tablet.

Here, hydrogen ion water is a kind of binder, more precisely hydrogen cation water, and is added for formulation formulation after granulation. The remaining hydrogen ions will have a beneficial effect on the human body.

In the present invention, hydrogen ion water should contain at least 1.2 ppm or more of hydrogen ions for functional expression, and preferably maintain 1.2-1.8 ppm.

In this case, the concentration of hydrogen ions can be measured through a hydrogen concentration meter, PH-35A.

And, sodium bicarbonate reacts with citric acid to rapidly increase foaming, thereby remarkably increasing the cleaning power.

In addition, citric acid improves sterilization and flexibility while soluble in water.

For example, the reaction of citric acid and sodium hydrogen carbonate is C ₆ H ₈ O ₇ (aq) + 3NaHCO ₃ (aq) → Na ₃ C ₆ H ₅ O ₇ (aq) + 3CO ₂ (g) + 3H ₂ O(l) It absorbs moisture in the water and reacts rapidly to promote the generation of carbon dioxide gas, thereby increasing the foaming, thereby maximizing the cleaning power.

And, cornstarch is a natural ingredient added to increase the viscosity and the bonding force between the components. In addition, cocamidopropyl betaine is added to promote foaming as well as foaming.

In addition, SLSA is a natural substance that contributes to enhancing the cleaning effect by lowering the surface tension of fibers by providing a hypoallergenic surfactant function in which lauric acid, a fatty acid of palm oil and amino acids are combined.

In addition, pancreatin (Pancreatin) acts as a proteolytic enzyme to break down proteins stuck in the fiber, and lipase (Lipase) is a fat hydrolase and acts to break down fat stuck in the fiber.

In addition, the aluminosilicate enhances the adsorption power to increase the decomposition and separation efficiency when it is stuck, and the sodium metasilicate adheres to the interface of the fiber and reduces the surface tension, thereby increasing the cleaning power.

In the present invention, in addition to these basic components, 10 parts by weight of allantoin, 15 parts by weight of glycerin, 20 parts by weight of hyaluronic acid, and 5 parts by weight of salt can be further added to 100 parts by weight of hydrogen ion water.

At this time, allantoin is absorbed into the laundry fibers and provides a cooling effect, skin soothing, cell activation and moisturizing effect upon body contact; Glycerin is used as an adjuvant to promote cleaning function, promote foam function, and promote surfactant function.

And, hyaluronic acid increases the flexibility of the fabric during washing, so that there is no need to use a chemical fabric softener; It is added to strengthen skin moisture and promote skin regeneration.

In addition, general salt is possible, but it is preferable to use Dead Sea salt produced in the Jordan region, which is upstream of the Dead Sea. It has a salinity 7-8 times higher than that of ordinary salt, so it is rich in various minerals and strengthens cleaning power. because it contributes to

Furthermore, with respect to 100 parts by weight of hydrogen ion water, 5 parts by weight of sodium sesquicarbonate to help maintain the wash water in a weak alkalinity to increase washing properties, 2.5 parts by weight of ethylenediaminetetraacetic acid to prevent rancidity, and the ability to decompose foreign substances at the interface. An additional 2.5 parts by weight of glycerol monostearate may be added to increase it.

In particular, sodium sesquicarbonate is a natural alkali agent _{and is expressed as Na 2} CO ₃ ㆍNaHCO ₃ ㆍ2H ₂ O. As a natural inorganic material, it is harmless to the human body without causing water pollution or environmental pollution (no skin irritation), and is easily soluble in water. It dissolves, the aqueous solution is alkaline, and it is added as a detergency enhancer or detergency enhancer to further strengthen separation and washing when protein is decomposed or stagnant.

In addition, the ethylenediaminetetraacetic acid (Ethylenediaminetetraacetic acid) is added to prevent rancidity due to oxidation, and glycerol mono stearate increases the activity at the laundry fiber interface to enhance the ability to decompose foreign matter.

On the other hand, the film can be a polyvinyl alcohol film as an eco-friendly material that dissolves well in water and does not cause water pollution.

The polyvinyl alcohol film is a thin film (eg, 0.01-0.02 mm), which is covered on the outer surface of the compressed formulation and then suction-compressed in a vacuum packaging method to completely seal the outer surface of the compressed formulation.

Therefore, since the film primarily blocks the contact between moisture and the compressed formulation, the shape retention of the compressed formulation can be prolonged, and when the compressed formulation is continuously in contact with washing water for washing for a certain period of time or more, the film itself will melt. It is released while the compressed formulation reacts.

A method for preparing a tablet for laundry, which is such a compressed formulation, is as follows.

The washing tablet manufacturing method according to the present invention consists of a film manufacturing step, a formulation powder formulation step, a compressed formulation manufacturing step, and a compressed formulation film coating step.

At this time, the film manufacturing step is a first process of mixing 30% by weight of polyvinyl alcohol, 55% by weight of water, 10% by weight of isopropyl alcohol and 5% by weight of a silicone resin; A second process of heating the mixture to 100 ℃; After the second process, a third process of coating a heating liquid with a thickness of 0.02 mm on a release paper and curing it to form a film is performed.

Here, polyvinyl alcohol as a water-soluble resin provides a property of being soluble in water, isopropyl alcohol contributes to plasticization of the resin, and silicone contributes to maintaining formability, ductility, and tensile properties.

And, the formulation powder composition step is based on 100 parts by weight of hydrogen ion water, corn starch 5 parts by weight, cocamidopropyl betaine 5 parts by weight, SLSA (Sodium Lauryl Sulfoacetate) 10 parts by weight, pancreatin 5 parts by weight, lipase (Lipase) 5 parts by weight, 10 parts by weight of aluminosilicate, and 15 parts by weight of sodium metasilicate were mixed and granulated with a spray granulator to make granular powder. It is the step of mixing wealth.

In addition, the compressed formulation manufacturing step is a step of filling the mixed powder in the bulk and then compressing it to make a formulation tablet.

In addition, the compression formulation film coating step is a step of coating the made film in a compression packaging method by covering the outer surface of the compression formulation.
