The “Claim” Is To Tell You About The Chemical Content
Black: pure chemical
Blue: Natural + Medicine
Red: Natural + Chemical composition
But what does it really mean? Absolutely nothing!
Those blocks are just colored markers, called “eye marks” or “color marks, are for the manufacture’s machines to cut and close the toothpaste containers. The colors absolutely have no correlation to the content inside the tube.
Although this was thought to be very intriguing, at least it made us pay attention to the ingredients in our toothpaste.
In all, do you know if your toothpaste is all natural or full of chemicals? You should really take a look! 🙂
