Ponceau 4R, also known as cochineal red, is a natural dye derived from the cochineal insect. It has been used for centuries to add color to foods and beverages, giving them a rich and vibrant red hue. However, one of the main drawbacks of Ponceau 4R is its instability, which can cause the color to fade over time or under certain conditions such as exposure to heat or light.
It adds a bright white color to coffee creamers, baked goods, chewing gums, hard-shell candies, puddings, frostings, dressings, and sauces. But the nanoparticles found in “food-grade” titanium dioxide may accumulate in the body and cause DNA damage—which is one way chemicals cause cancer and other health problems.

Scattering is strong when the difference in the refractive index of particle & matrix, Δn = np - nm, is big
The refractive index of binders used in coatings and inks is around 1.55. Titanium Dioxide is preferably used as a scattering source because the pigment does not absorb visible light and it has a high refractive index.
