People think the coloured square on your toothpaste is telling us something about the chemicals inside…here’s what it really means
Many believe the tiny symbol on the bottom of the tube indicates toxic content
HAVE you ever noticed the coloured square on the bottom of a toothpaste tube?
The tiny symbol, on the sealed end of the tube, comes in green, blue, red or black.
And many believe it is a secret code to let you know how toxic the ingredients are.
Articles on various websites have claimed the colour indicates the number of chemicals in your morning mouthful.
The theory is that:
- Green means a completely natural toothpaste
- Blue means the toothpaste’s composition is natural in combination with medicines
- Red means natural plus chemicals
- Black equals all chemicals
But before you go rushing to the bathroom cabinet to throw away your ‘toxic’ toothpaste, here’s the truth.
The whole thing is a myth.
The squares are actually just part of the manufacturing process, and are called “eye marks.”
The hidden information in these coloured squares are read by light beam sensors and literally just tell the high-speed machinery where the packaging needs to be cut and folded.
