Toothpaste tube bottom color and composition about is nonsense

Cosmetic market has recently been hot toothpaste specific composition and the color of its tail has said there is a relationship, if it is red, represents the pure natural ingredients, and black, said its composition, chemical composition, is pure natural green words. Dash out, a lot of people are holding their toothpaste to related department for that. It is, in effect, there is no scientific basis, China clean oral care industry association has made a major statement: toothpaste tube at the bottom of the article is in the machine for sealing a signature, facilitate subsequent production process, so with the color of tube end as whether it contains chemical composition is nonsense. Relevant researchers said that at the end of toothpaste tube red, blue, black, green, the color of the article, just in order to in the process of production, toothpaste to seal the key point of the machine can be a very good induction to the correct position, and then complete the product, the color is just a product of auxiliary function, not the so-called toothpaste composition indicate. In theory, any color can be induced, but in the process of production, the operation of equipment is different, the sensitivity of the electric eye is different, so in most cases is to use black as induction, thus greatly improve the yield of the product. Actually can from toothpaste to compare on market, most of them are using black, other colors are very low. Through the above analysis, I believe many people know that the color and composition of the bottom of the toothpaste tube is no relationship, toothpaste is not only the production, as some cosmetic products is through the hose packaging, it can be found at the bottom of all sorts of color mark. Experts suggest that don't always hearsay, all need a certain amount of investigation and research, it is concluded that the correct answer to believe or do. If couldn't be verified based on his capability, consult relevant departments, through scientific validation to give true answer. Editor: wen-jia guo
