What does Colored Square on Toothpaste Tubes tell you ?
Did you know that Toothpaste Tubes have information about its composition in the form of Color Codes at the Bottom? Check the square at the bottom of the tube and match its color with following table.
Blue : Natural + Medicine;
Red : Natural + Chemical composition;
Black : Pure chemical.
This is a false messages being propagated via chain Mails, Social Media and various other means. The color has got nothing to do with the Chemical Composition. According to FDA rules, the Chemical Composition has to be printed in words on the tube or wrapper of the Toothpaste.
The colored square on tubes referred to in the message, are related to the packaging process. The marks are known in the packaging industry as “eye marks” (or sometimes “eye spots”). They do not in any way indicate the chemical content of the tubes they are displayed on, regardless of what colour they are. That is not their role.
