In recent years, color-changing lipsticks have also been popular for a while.
The principle of color-changing lipstick is actually the colorant – bromate fuel
The commonly used bromic acid dye is tetrabromofluorescein, also known as “eosin red”, the lipstick or mouth infrared surface is orange, and it can be made into a transparent color-changing lipstick. When applied to the lips, it becomes bright red due to the change of the PH of the lips. In addition, the temperature of the individual lips, the background color and the amount of application are different, which constitutes the phenomenon of “thousands of people and one thousand colors”.
Bromic acid dye is a discoloration phenomenon that occurs after the action of the lip tissue, and the color and luster ratio is firm and durable.
Considering that these lipsticks are not 100% eaten (wiped off, on cups and utensils, and eaten by boyfriends…), let’s take the average amount of lipstick used as the lipstick that is eaten, which can be eaten every year. The next 9 grams of lipstick, about the amount of 2 lipsticks.
Carotene, henna, plant sources, etc. in the promotional content are pure nonsense. This type of color-changing dye has certain side effects, and it is recommended that you use it sparingly.
