Why colored stripes on toothpaste are needed: dispelling a common myth

The colors of the stripes on toothpaste tubes are believed by some to carry specific information, perpetuating a popular myth. Toothpaste with a black stripe is sometimes dubbed as particularly dangerous, supposedly containing aggressive chemicals.

Another version suggests that the stripes on the paste indicate its abrasiveness level. OBOZREVATEL debunks this common myth about the significance of the color markings on the tube.

Online suggestions often claim that the stripes on a toothpaste tube serve as a form of labeling. Green is deemed "safe," signifying that it contains only natural ingredients; red indicates the presence of both synthetic and natural substances; blue suggests a ratio of 20% natural to 80% chemical components, while black signifies an aggressive synthetic composition.

However, this theory doesn't hold up to scrutiny, just like the idea that the stripe indicates the level of abrasiveness. The analogy here suggests that a black stripe represents the most abrasive paste, potentially causing enamel scratches, while a green stripe is deemed suitable for daily use, often associated with herbal paste.

In reality, the colored markings on the tube are merely indicators for packaging machines. They exist to enable the conveyor sensor to recognize the marking and cut the tube at the appropriate location. The fundamental rule is that the mark must contrast with the background color; otherwise, the sensor won't register it.

Therefore, these stripes are technical elements and do not determine the composition, abrasiveness, whitening level, etc. Frequently, such marks are created using a color that already appears in the packaging design.

To identify natural toothpaste, look for certifications from organizations that verify natural products.

Toothpaste always contains active substances like fluoride, vitamins, medicinal extracts, or essential oils (such as menthol for a refreshing flavor). The raw materials for making toothpaste can be of both natural and synthetic origins.

By the way, experts do not recommend wetting your toothbrush before brushing. Recent studies indicate that dry brushing may be more effective in combating bad breath. Brushing without adding water can better address halitosis. Read the article to discover the proper way to brush your teeth for optimal oral and enamel health.
