Description

Preparation method for toothpaste of complex granule additive

The present invention relates to a method for producing activated carbon alone or granules containing activated carbon and zeolite as an activated carbon composite granule, and a toothpaste composition containing a certain amount of the composite granules. More specifically, zeolite with ion exchange ability effectively removes divalent ions that cause tartar due to the presence of trace amounts of activated carbon and auxiliary components in the fern when zeolite is contained. The present invention relates to a toothpaste granule and a toothpaste composition containing the same, which effectively removes bad breath and pigments. In general, when caries are eaten with sugar-containing food, bacterial growth in the oral cavity is promoted, and dentin breakdown occurs. Plasma generation by bacterial membranes is plaqued by deposition of polyvalent ions, and pigments are deposited on tartar. It is preferable to remove the yellowish brown because it is changed in appearance and becomes a major cause of periodontal disease. Looking at the conventional techniques for preventing such plaque and tartar formation as follows.

Korean Patent Publication No. 012156 attempts to suppress calculus formation by removing polyvalent ions such as calcium using neutral zeolite powder or granules with neutralized zeolite. This technology uses neutralized zeolite because the storage stability of toothpaste is lowered by alkaline zeolite when zeolite is added to toothpaste.However, a large amount of zeolite must be used because most zeolite crystals are destroyed in the process of neutralization and thus the desired ion exchange capacity is lost. Achieve the desired purpose. However, in order to eliminate the bitter taste of toothpaste due to excessive use of zeolite, there is a disadvantage in that the use of sweeteners should be increased.

In EP 0473171 or U.S. Patent 5206010, the granules were made by using an excessive amount (5-10%) of an insoluble inorganic substance and an organic binder and applied to toothpaste for the purpose of removing tartar, but they were used for the purpose of removing tartar by granules. There are many disadvantages, such as the addition of an excess of an organic binder which is not an impurity.

In WO 02/45677 zeolite granules were used to remove tartar and plaque, but this was not used for zeolite but only for removing tartar and plaque by particles. In Korean Patent Laid-Open Publication No. 2002-0086064, a toothpaste composition containing charcoal powder was invented and the toothpaste composition which is effective in removing nicotine deposited on the tooth was invented, but the color of the toothpaste was black by using black powder in the toothpaste. Rejection or sour taste.

The present invention eliminates the color bleeding of the toothpaste when applied to the toothpaste by applying the activated carbon composite granules having sufficient strength not to be destroyed in the toothpaste manufacturing process, the activated carbon composite granules for the addition of good toothpaste and anti-frag It aims to provide.

       The composite granules for toothpaste addition of the present invention contain 40 to 90% by weight of activated carbon and auxiliary components and 2 to 20% by weight of a binder. As auxiliary components, zeolite, calcium carbonate, silica, aluminum hydroxide, phosphate, and the like can be used. That is, depending on the purpose of the toothpaste can be selectively used in one component or in combination. For example, for the purpose of removing polyions, the zeolite is used alone or in combination, and when added to the polishing component is prepared by adding aluminum hydroxide. At this time, the content of the auxiliary component can be adjusted within the range of 1 to 90% by weight relative to the weight of the activated carbon, and beyond this range, the performance of the auxiliary component may be degraded or the effect of the activated carbon cannot be expected. As the binder, organic materials, clays, silicic acid and silica can be used, and a minimum amount is preferable for the purpose of improving the performance. However, when the strength of the application is a problem, it can be used within 20% by weight. In particular, the silica or silicic acid-based binder is also used as an auxiliary component, there is an advantage that can be used without limitation of the amount added. In addition, the characteristics of the present invention was prevented by coating the granules in the toothpaste manufacturing process to prevent color bleeding to the toothpaste base. The coating material of the present invention can be organic and inorganic coating, but is preferably coated with a silicic acid system, which is a silicic acid is added to the toothpaste and also has the advantage that the transparency and strength can be adjusted when coating.

Hereinafter, the present invention will be described in detail.

Activated carbon has a large specific surface area and has been used as an adsorbent since the past. Adsorption characteristics of organic matter present in gaseous or liquid materials are superior to any materials. Therefore, using activated carbon can effectively remove the odor generated in the oral cavity. In addition, the zeolite that can be used as an auxiliary material in the present invention has an ion exchange ability to inhibit tartar formation and to reduce the amount of surfactant used by preventing the reduction of the effectiveness of the surfactant added to the toothpaste by polyions. You can. In addition, by using aluminum hydroxide, which is widely used as a skirting agent, as an auxiliary material, the deodorizing ability of activated carbon can be improved, and a separate skirting agent addition process can be omitted, thereby simplifying the process. And silica or coated silica that can be used as an auxiliary material is a material that is used a lot to give a refreshing and refreshing feeling after brushing in the existing toothpaste prescription has the advantage of not using or reducing the use of silica when granulating the present invention. . In the following description, the granules are added to the granules and mixed with the activated carbon, the auxiliary components, and the binder in a proportion to achieve the desired purpose. After mixing, granulation is carried out while gradually adding about 20 to 45% by weight of water, depending on the type and amount of the material. When particles are formed, silica powder is applied to coat the coating and then dried to obtain a composite granule, or 3-5% sodium silicate solution is sprayed on the surface of the particle and further gelling agent (ammonia water, sodium bicarbonate, Sodium carbonate, inorganic acid) aqueous solution was further sprayed to gel the sodium silicate solution, dried and sieved (0.1-0.7 mm) to obtain granules of the desired size and applied to toothpaste.
