Does the black stripe on the bottom of toothpaste mean toxic? ! I didn't expect these "colored bars" to be!
(Source: testingmama) A message on the Internet that "black toothpaste is poisonous" is actually an online rumor! Now I want to tell you that toothpaste does have stripes of different colors, but the statement that black is poisonous is simply a rumor. Don't be cheated! (Source: idv) I took out the three-in-one soft-shell toothpaste I bought at home the other day. I took a closer look and found that there were really colored bars at the bottom. Some brands of toothpaste have a long dark blue color bar at the bottom of the tail. And there is toothpaste with black bottom color bar. Is the toothpaste you touch every day really a chemical? That's bullshit! (source: idv)? According to the classification, toothpaste belongs to the cosmetics industry. In China, a reporter went to a toothpaste factory to learn about online rumors. If you want to enter the toothpaste factory, the reporter must change clothes twice and take an air shower for disinfection before entering the filling room of the enterprise. The machine conveys the prepared toothpaste raw materials to the filling line. The reporter saw that on the soft shell of toothpaste used by this enterprise, the background color strip was green. The reporter asked the general manager of the factory, "What is the function of this color bar? Can it really represent the ingredients in it? The general manager said: "this color bar is applied by the positioning sense of the packaging machine." The reporter saw that the toothpaste soft shell was filled with raw materials and placed on the base. At this time, the toothpaste is round and faces in all directions. After filling the toothpaste, put it on the automatic tail sealing machine. The base of the laser-induced soft shell color strip on the tail sealing machine automatically rotates with the toothpaste to seal the toothpaste tail. The toothpaste that comes out at this time is even. "The use of color bar induction is to ensure that the toothpaste is packaged in the correct position when sealing the tail. The general manager said: "The colored bars represent the ingredients of toothpaste, which is purely a rumor and has no scientific basis. For the effect of induction, these colored bars appear in dark colors, mostly blue, black, green and so on. There will be no light color. At present, the same automatic tail sealing machine is used in the industry, relying on inductive positioning. (Source: idv) Therefore, the color of the color label at the end of the toothpaste hose depends on the packaging design of the toothpaste hose. Generally, the existing color on the hose is obviously different from the background color, which is easy to be perceived by the equipment and has nothing to do with the product composition. Toothpaste consists of many ingredients, and the ingredients of each toothpaste are slightly different. Consumers can know the specific ingredients of toothpaste through the ingredient list on the toothpaste package. Toothpaste has no natural and chemical classification, as long as the raw materials used meet the "Specifications for Raw Materials for Toothpaste". So dear friends, don't be influenced by false rumors on the Internet. The most important way to check is the raw materials on the packaging label! Share this article with your friends so that they won't be cheated again!
