The colored rectangle actually has nothing to do with the toothpaste’s formulation. It’s simply a mark made during the manufacturing process. The marks are read by light beam sensors, which notify machines where the packaging should be cut, folded, or sealed. These marks do come in many colors and they’re not limited to green, blue, red, and black. Different colors are used on different types of packaging or with different sensors and machines. In other words, all the colors mean exactly the same thing. If you really want to know what’s in your toothpaste, you can always read the ingredients printed on the toothpaste box.
Try using two or three different types of toothpaste daily. Use Pronamel at night and a whitening toothpaste in the morning, alternating between them. You'll notice the difference. Brush your teeth more than 2 minutes with the electric brush will make the difference.
多謝村長！真係唔識！❤😊🙏🙏👍👍
該色條被稱為「電眼定位點」，用於牙膏在生產過程中封尾和識別作用，當牙膏已經填滿包裝管，生產機器必須感應到顏色條才能夠更準確的定位，再自動封住牙膏管，而且使用越明顯的顏色，激光定位感應才會更準確，所以在牙膏的包裝上我們通常會看到黑色、綠色、藍色和紅色這四種顏色，顏色全憑生產商的喜好。而且不只是牙膏，我們常見的日用品如：洗面奶、護髮素、護手霜等等，高露潔官網都在幾年前有澄清。
一般牙膏多為乳劑、膏劑及液劑，主要用於清潔牙齒、保持口氣清新，常見的組成為研磨劑、界面活性劑、黏結劑、保濕劑、防腐劑及香料等。
牙膏管底的顏色條，不論是綠、紅、藍或黑，均與內含成分無關，主要是牙膏製作軟管時，為了定位、防止偏移而使用的印刷標記。
以我生產工程背景和经验，这个色標用作定位功能是正確。fact check 后亦確正颜色与成份無關。
今次靚仔村長，分享非常有趣😁我用牙粉的，好好用，非常合適我
村長好叻啊❤
綠色純天然
藍色保護牙齦
网上早就辟谣过，其实标签只是用作生产过程的用于识别的一种手段,与牙膏中的成分其实毫无关系。
this information is helpful, but I don’t really see this coloring in USA
👍🏻👍🏻👍🏻

不要用美白牙膏，會傷害琺瑯質。Rapid 那隻可以防敏感
多謝 村長 好多人真係唔知 唔識 長知識
小説中花無缺不是廢人
死囉！😂原來我同村長性格和食嘢口味好似😢
又长知识了
