The difference between lip balm and color-changing lipstick

Both lip balm and color-changing lipstick can moisturize the lips and prevent dry and flaky lips. However, the difference is that color-changing lipstick can change color according to the temperature or pH value of the lips after application, making the lips look fresh, plump and shiny.

Why does color-changing lipstick change color?

The main ingredients of color-changing lipstick are oil (castor oil), fat (lanolin) and wax (beeswax). Beeswax can increase the hardness of lipstick; lanolin, as a solvent for pigments, can improve the dispersion of pigments; castor oil gives lipstick viscosity and improves the coloring of lips. Eosin, a dye widely used in lipstick, is an acid dye, commonly known as solvent red 43, also known as tetrabromofluorescein yellow or tetrabromofluorescein, and its English name is tetrabromofluorescein. The color changes depending on the pH value. When the pH value is higher than 4, the solvent red 43 in the color-changing lipstick turns into dark red.

Although lips are neutral, saliva is generally weakly alkaline, and the saliva on the lips will also become weakly alkaline, that is, the pH value is above 7. The color-changing lipstick made with acidic ising pigment has a pH value of 3. When Solvent Red 43 lipstick is applied to the lips, it will change color. Acid pigments act as acid-base indicators! Test the pH value on the pH test paper. The pH value produces different colors. The pH value of each person's saliva is different, and the pH value of the lips is different, so everyone wears color-changing lipstick.

The main raw materials of color-changing lipstick

1. Angle-changing pigments. Commonly known as chameleon pigment, the same product will have different colors when observed at different angles. For example, at 90 degrees it appears blue, but at 60 degrees it turns purple, and at 30 degrees it turns gold, and so on.

2. Photosensitive color-changing pigment. This pigment usually appears as translucent off-white or light color in the absence of ultraviolet radiation, and appears as red, green, blue, purple, orange, sky blue, yellow, etc. under sunlight with ultraviolet radiation. It is sensitive to ultraviolet rays.

3. Thermochromic pigment. It is sensitive to temperature. From low temperature to high temperature, the color shows two changes, mostly low-temperature colored and high-temperature decolorized mode.

4. Humidity-sensitive color-changing pigment. It is sensitive to humidity. When it encounters water vapor or water, the color will disappear and become transparent. Usually, white becomes transparent. The white pattern can be designed to become a colorful pattern. You can imagine how interesting it is for a piece of clothing with a white pattern to turn into a colorful pattern after being rained on.

Color-changing lipstick will appear greasy when applied on the lips, but lipstick will not. In makeup, lipstick is more used in cosmetics because the color it creates can be more vivid, and it is more suitable for use in some important and formal occasions.
