claim: Blocks of color printed on toothpaste tubes indicate whether the toothpaste is made of safe ingredients
evidence: Incorrect: Colored squares printed at the ends of toothpaste tubes aren’t a secret code for the safety of toothpaste ingredients. Instead, they allow light sensors on the toothpaste production line to recognize the end of the tube, so that tubes can be filled, cut, and sealed correctly. [...] In the clip, TikTok celebrity and podcast host Carlos Juico claimed that color blocks at the end of toothpaste tubes indicated whether the toothpaste ingredients were natural or "chemical". More specifically, he asserted that a green color block meant the toothpaste was all-natural; a blue color block meant the toothpaste was "natural plus medicine"; and a black color block meant the toothpaste was "all chemical". [...] In summary, the conspiracy theory that toothpaste tubes carry a secret color code indicating the safety of toothpaste ingredients is baseless. If people wish to know which ingredients are present in their toothpaste, they can simply read the ingredient list printed on toothpaste packaging.
