I think it was this
Green: Natural, Blue: Natural + Chemicals, Red: Natural + Chemicals, Black: Chemicals
That's what it means

OK

pu2. On social media or internet blogs,
"If the vertical line at the end of the toothpaste is black, it is 100% chemical, if it is red, it is a mixture of chemical and natural, and if it is green, it is 100% chemical
It's 100% natural."
This is not true when it goes around.
The thick line at the end of the toothpaste container is called an eye mark.
When a chemical company or cosmetics company produces tube-type products such as toothpaste, you have to wrap the opening with a lid first
Add contents like toothpaste. It's the opposite of what we use.
The production process is designed to cut and seal the back of the tube, when the sensor of the machine that puts the contents in and seals the position
It is a mark that sets the center so that you can read and work well. This eye mark is not only toothpaste, but also cleansing, sunscreen, and tube type
Everything is marked on the product.
There is no special reason for each product's color to be different, but it uses a random color that is different from the background of the product.
For example, if the design is white toothpaste, mark it with a black barOr you can put a white mark on a red product.
The company just takes care of it, but there are the most products in black.
I looked it up and it says it's like this
