What is the color bar on the bottom of the toothpaste tube? Does the color on the bottom of the toothpaste tube represent the ingredients of the toothpaste?

Recently, it has been widely circulated on the Internet that the color at the bottom of the toothpaste tube represents the different ingredients of the toothpaste, but is this really the case? Does the color at the bottom of the toothpaste tube really indicate the ingredients of the toothpaste? Is black really the so-called chemical composition? In fact, the color strip at the bottom of the toothpaste package is used for positioning and identification when the product is sealed during the toothpaste production process. It is called the electric eye positioning point. Commonly used colors include red, blue, green and black.

Popular Science: Toothpaste

A paste used for brushing teeth, made of glycerin, tooth powder, white glue powder, water, saccharin, starch, etc., and packed in a metal or plastic hose. It is a kind of daily necessities. It is a paste, cool and fragrant, mostly stored in a metal hose, for brushing teeth, and has a tooth-cleaning effect.

The American Dental Association defines toothpaste as: Toothpaste is a substance used with a toothbrush to clean the surface of teeth. The China Toothpaste Industry Association defines it as: Toothpaste is a daily necessity used with a toothbrush to clean teeth, protect oral hygiene, and is safe for the human body.

Is toothpaste healthy ?

Toothpaste is a necessity in life. There are many kinds of toothpaste on the market now, and a considerable number of them are fluoride toothpaste. However, experts point out that there are great risks for children under 6 years old to use fluoride toothpaste, because fluoride is a toxic substance. Excessive fluoride will not only cause thin teeth, but also reduce the hardness of bones. Fluorine has been identified by the World Health Organization as a trace element with potential toxicity, ranking first with lead and mercury trace elements. There are more than 20 provinces and cities in China that are high-fluoride areas. Using fluoride toothpaste in these areas will undoubtedly make things worse.

Toothpaste ingredients

Toothpaste is a complex mixture. It is usually made of abrasives (such as calcium carbonate, calcium hydrogen phosphate, calcium pyrophosphate, silicon dioxide, aluminum hydroxide), moisturizers (such as glycerol, sorbitol, xylitol, polyethylene glycol and water), surfactants (such as sodium lauryl sulfate, sodium 2-acyloxy bond sulfonate), thickeners (such as carboxymethyl cellulose, antler pectin, hydroxyethyl cellulose, xanthan gum, guar gum, carrageenan, etc.), sweeteners (such as glycerol, sodium cyclohexylamine sulfonate, sodium saccharin, etc.), preservatives (such as potassium sorbate and sodium benzoate), active additives (such as chlorophyll, fluoride), as well as pigments, flavors, etc. Special toothpaste is a toothpaste with special properties. Fluoride toothpaste contains active substances such as sodium fluoride, stannous fluoride, sodium monofluorophosphate, zinc fluoride, etc., which are effective in preventing tooth decay. Chlorophyll toothpaste contains chlorophyll, which is effective in preventing gum bleeding and bad breath. Enzyme toothpaste can decompose residual food, and is effective in cleaning the mouth and preventing moths. Medicated toothpaste adds drugs to the toothpaste to treat oral diseases. The Huangcen toothpaste and Caoshanhu toothpaste sold on the market have obvious effects on relieving and treating gum bleeding, gum swelling, bad breath, and tooth hypersensitivity. Compared with each toothpaste on the market, there will be slight differences in ingredients, but they are generally the same.

The function of the color block at the bottom of toothpaste

Then does the color block at the bottom of the toothpaste really indicate the ingredients of the toothpaste? In fact, many people have been confused by this rumor. The color block at the bottom of the toothpaste is actually just a mark left by the toothpaste manufacturer. Let us explain below:

This color block is a mark left on the production line during printing. Its function is probably :

1. Pantone calibration;

2. Mark the position where the toothpaste tubes are cut according to the standard size on the assembly line; let the computer recognize it and tell it what changes should be made here, such as cutting, skipping, or stopping.

3. Mark for toothpaste pattern alignment;

4. A detection mark for electric eye quality inspection (on the production line, products quickly pass through an electric eye, and reserved marks are used to detect whether the toothpaste position, pattern, etc. are correct).

Moreover, in the classification of toothpaste, there is no such classification as all natural/chemical ingredients. These are overlapping and unclear definitions.

To sum up, the rumor circulating on the Internet that "the color of the bottom of the toothpaste tube represents the following: 1. Green means pure natural; 2. Blue means part natural and part medicinal ingredients; 3. Red means half natural ingredients and half chemical ingredients; 4. Black means all chemical ingredients" is completely misleading the general public. I hope everyone will not blindly follow suit and repost or spread it.
