The black bar at the bottom of the toothpaste is poisonous. It’s a rumor

There is a message circulating in the QQ space of friends: “immediately check the bottom of your toothpaste tube. If it is a black bar, throw it away immediately! Today, I know the meaning of the color bar at the bottom of the toothpaste. Green: pure natural; blue: natural + medicine; red: natural + chemical ingredients; Black: pure chemistry. Try to choose green and blue! Most domestic toothpaste, including children’s toothpaste, are chemical!” This view makes people jump.

toothpaste does have different color bars

The reporter took out several tubes of soft shell toothpaste that he had bought at home the other day. After a careful look, he found that there were really color bars at the bottom. “Scutellaria baicalensis” and “Zhonghua” have a 1cm long color bar at the bottom and the center, which are dark blue. The bottom color bar of a “black” toothpaste is black. The “little white rabbit” and “Tianqi” children’s toothpaste at home are also black. Is the toothpaste that comes into contact with the mouth every day really a chemical substance? This reporter conducted an investigation and interview.

According to the new division of administrative functions, toothpaste is classified as the cosmetics industry, which is supervised by Quzhou market supervision and Administration Bureau. Yesterday morning, the reporter came to the protection and Chemical Department of the Bureau. Director Wei Shaoping introduced that there were four toothpaste manufacturers in our province, one of which happened to be located in Shuanggang street, Quzhou.

visited toothpaste manufacturers

“What is the role of this color bar? Does it really represent the ingredients in it?” This reporter and the food and drug regulatory personnel of Kecheng district went to this “Zhejiang Taikang Biotechnology Co., Ltd.” to find out.

The toothpaste produced by this enterprise is mainly supplied to Guangdong and Hong Kong markets. At this time, the workers were assembling toothpaste on the production line.

After two times of dressing and air shower disinfection, the reporter entered the filling room of the enterprise. The prepared toothpaste raw materials are transported to the filling line by the machine. The reporter saw that the bottom color bar on the soft shell of the toothpaste used by this enterprise was green.

“This color bar is used for the positioning sense of the packaging machine.” Chen Linxin, the general manager, told reporters while demonstrating. 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 the toothpaste is filled, it is applied to the automatic tail sealing machine. The laser on the tail sealing machine senses the color bar on the soft shell. The base automatically turns with the toothpaste and seals the tail of the toothpaste. At this time, all the toothpaste coming out is neat and uniform. “Sensing with the color bar is to ensure that the toothpaste package is in the correct position when the tail is sealed.”

Manager Chen said that the color bar represents the composition of toothpaste, which is purely rumored and has no scientific basis. “In order to sense the effect, these color bars appear in dark colors, mostly blue, black, green, etc., and there will be no light color system.” Manager Chen introduced that the same automatic tail sealing machine is used in the industry at present, which relies on induction positioning.

the Industry Association issued a clarification

The reporter then found an explanation on the official website of China oral hygiene and care products industry association. In the explanation on the bottom color mark of toothpaste tubes, it was stated that rumors such as “look at the color, buy toothpaste” and “different components of the bottom color bar of toothpaste tubes” were frequently spread on the Internet, which caused certain puzzles and doubts to consumers in purchasing.

In this regard, the association made corresponding clarifications and explanations. According to the instructions, the color of the color mark at the end of the toothpaste hose depends on the packaging design of the toothpaste hose. Generally, the color that is already on the hose and clearly different from the background color and easy to be sensed by the equipment will be selected, which has nothing to do with the composition of the product.

Toothpaste is composed of a variety of components, and the components of each toothpaste are slightly different. Consumers can know the specific added components of toothpaste through the composition table on the toothpaste package. There is no classification of toothpaste as pure natural or pure chemical. The raw materials used only conform to the specifications for raw materials for toothpaste.
