A few days ago to visit my friend came. It was nearly noon, and before sitting down at the dinner table, she went to the bathroom to wash his hands. Returning to the kitchen, she was horrified asked me "why should I buy toothpastewith black markings because she 100% consists of chemical substances, that very harmful for our body ". For half an hour, a friend told me about the dangers of pasta with black markings, and insisted that it is necessary to buy only the paste with green marking, or even at the worst with red.
After the departure of a friend, I was very impressed by her story. After going to the bathroom, I pulled all the tubes of toothpaste and really saw them marking different colors. I turned Tube 2 with red, 2 green, 1 blue, and 1 black, just someone who has seen a friend. I decided to read about the characteristics of each color in more detail on the Internet. As it turns out there are many sites that given decrypting data marks, here for example:
Black color: paste contains 100% chemical and abrasive particles. Blue color: paste made from 80% of the chemicals and abrasives. Red color: paste contains 50% chemical and abrasive particles. Green: in the paste no chemicals.
I also met many other variations refer to colored markings: damage to the teeth, damage to the gums, the risk of periodontal disease, and of the most ridiculous "the recommended duration of application of the paste without harm to health". And of course all the green label marks represents the best indicator and black, respectively, the worst since the paste with a black label "categorically can not be used on an ongoing basis."
But by having dug deeper and read the information from authoritative sources, I realized that these markings It does not denote anything, absolutely nothing! This is confirmed by the fact that in interstate standard GOST 7983-99 on general technical conditions toothpaste not a word about the data markings. In fact it is not even marking and svetometki destined for the assembly line, it is for them it is guided where to make the cut, and then wrap the plastic in the shape of a tube. The color of the label simply exposed in the workplace. Some manufacturers for marketing purposes, specifically svetometki change color to green, to inspire confidence in buyers. So instead of targeting any tag, just read the composition! Of course, in the evening I enlightened her friend, who was surprised no less than I day of the same day.
