Abstract

The invention discloses a method for producing a toothpaste additive from rice husk as a raw material. According to the method, the rice husk is subjected to steps such as carbonization, impurity removal, activation and crushing, and the crushed material is further mixed with pearl powder and algalpolysaccharideso as to obtain the toothpaste additive. The toothpaste additive produced by using themethod is prepared from natural substances, namely the rice husk, pearls and algal polysaccharides, has good capabilities of removing dental plaques and adsorbing tooth stains, in addition, has effects of nourishing gums and whitening teeth, and is capable of preventing oral ulcers, swollen and painful gums, dental caries in children, and the like, and promoting mouth health.

Description

technical field [0001] The invention relates to the technical field of toothpaste additives, in particular to a method for producing toothpaste additives using rice husks as raw materials. Background technique [0002] Toothpaste is a commonly used cleaning product in daily life. It is a kind of toothpaste used to clean teeth and keep teeth beautiful and white. Toothpaste has a long history. With the continuous development of science and technology, the production process and equipment With continuous improvement and perfection, various types of toothpaste have come out one after another, and the quality and grade of products have also been continuously improved. People often add some additives to toothpaste to make it have various functions. [0003] Rice husk, also known as rice husk, is the outer shell of rice. The bulk density of rice husk is 96~160kg.m -3 , After the rice husk is crushed, the bulk density can reach 384~400kg.m -3 . Rice husk is rich in cellulose, l...
