Same as calcium carbonate toothpaste (03101), Chinese herbal medicine preparations can be added during the kneading process. Preparation method
The pre-release glue method first disperses the thickener evenly in the wetting agent according to the formula to make a uniform and integrated dispersion. In addition, saccharin, preservative and corrosion inhibitor are dissolved in deionized water heated to 40-50 ℃, and the aqueous solution is added to the prepared dispersion under stirring to expand into uniform glue, and then foaming agent is added. After the glue is properly aged, add the pre-weighed essence and friction agent in turn, and fully stir, which is the paste blank. Under the high shear action of colloid mill, various particles are further dispersed to achieve uniformity. Finally, the paste is deaerated by vacuum to become a compact, delicate and glossy paste, which is filled to produce the finished product.
Direct mixing method This process is suitable for larger mixing equipment. The components are weighed according to the formula ratio and directly put into the paste mixing machine. The feeding order is glycerin, sodium carboxymethyl cellulose, deionized water or Other water-soluble additives, foaming agents, flavors, and friction agents. Then the components are dispersed and evenly mixed by strong stirring, kneading and mixing. Similar to the pre-release glue method, the paste is made by homogeneous grinding and vacuum degassing. Finally, the finished product is filled and packaged.
