Why is toothpaste striped?

Answer 1

The diffeerent stripes are separated in different compartments in the tube, the white in the centre and different colours (blue, red, etc) on the ends with a small hole at the nozzle. When you squeeze all 3 compartments are compressed and all 3 parts come out and just before then come out of the tube they join. quite simple!

Answer 2

There are actually 2 tubes. First, a small tube is inserted into about the first fifth of the tube. It is filled around with red, leaving a tube in the middle for white. Slots are cut into this tube, letting the red come out. The rest is filled with white. When the white is squeezed, it pushes on the red. If it all works out, the white and red are squeezed at the same time, letting the red push through the slots in the inner tube and onto the white leaving a striped toothpaste. I know it is confusing, but reread it a couple times and try to picture it and you will get the idea.

Answer 3

The stripes are not added to Aquafresh toothpaste after the fact. Instead, each color of toothpaste is loaded separately into the tube so that when it comes out, a bit from each area comes out at the same time forming stripes.

Answer 4

inside the tube is three different road lanes that meet at the junction which causes a crash of toothpaste colours..................

Answer 5

It's just a marketing ploy ! The 'ingredients' in toothpaste are more or less the same - regardless of the brand. Some manufacturers put stripes in to make it more appealing to children.
