Tubes of toothpaste have four different color stripes, depending on their composition. Do you know what they mean? Or did you think you thought what they meant?
Contrary to popular belief and much research, the colors were believed to stand for the ingredients in the toothpaste
• Green color stands for a completely natural toothpaste
• Blue color means the toothpaste’s composition is natural in combination with medicines
• Red means natural plus chemicals
• Black color equals all chemicals”
Myth, debunked, completely, the colored squares on the bottom of toothpaste tubes have nothing to do with the toothpaste ingredients at all.
They are, actually, the manufacturer’s process’ artifact, also known as color marks, printed marks, or eye marks.
To give an indication to the robotic sensor as to exactly where packaging should be crimped, cut, or bent during the production process. For the “robotic sensors” to read the colors more efficiently, they are typically darker than the other colors on the tubes. This is also the case especially if the manufacturing process takes place in a different facility than the packaging of the toothpaste.
Their purpose is to indicate to a robotic sensor where the packaging should be cut, bent, or crimped during production. These colors are usually designed to be darker than the rest of the packaging, so they can be machine read more easily.
I wanted to further investigate this information for myself. I went on several toothpaste websites seeking their answers to the question” what does that color stripe mean?”
Per Colgate’s website:
“The marks help light sensors detect the end of the tube so that the machines used to prepare the tubes to know where to cut or seal them.”
Per New Health Advisor for Daily Health Care:
“The toothpaste color code is meant for package matching and different colors are meant for different types of packaging or sensors and not the content.”
The “Crest” website did not address the topic/ question from my research.
This was actually new information to me, for years, I truly believed that these “color stripes” were a telltale sign of the ingredient differences and possible chemicals in the tubes of toothpaste.
If you have doubts about the ingredients in your toothpaste or feel that the color strip on the back of the toothpaste tube has anything to do with the ingredients, I definitely suggest calling the manufacturer.
There you have it! All part of the processing and manufacturing process.
Good to know info!
