Lithopone’s historical significance is further accentuated by the advancements and modifications that followed its inception. The 1874 patent by J.B. Orr, for instance, ushered in a new white pigment—Orr’s Zinc White. This innovation was attained by co-precipitating zinc sulfate and barium sulfide, followed by a calcination process. Further refinements marked the subsequent decades, the most notable being the enhancement of lightfastness achieved in the 1920s by introducing small amounts of cobalt salts before calcination.

Titanium dioxide is widely used as a color-enhancer in cosmetic and over-the-counter products like lipsticks, sunscreens, toothpaste, creams, and powders. It’s usually found as nano-titanium dioxide, which is much smaller than the food-grade version (7Trusted Source).
In beauty and personal care products, the ingredient is listed with its colour index (CI) number ‘CI 77891’. When nano grade titanium dioxide is used in our sunscreens, this is referenced as ‘titanium dioxide’ [nano] in the ingredients list.
