Lithopone was developed in the 1870s as a substitute for lead carbonate (lead white), to overcome its drawbacks of toxicity and poor weathering resistance. Within a few years, titanium dioxide displaced lithopone to become the white pigment (PW6) par excellence in the industry and the world’s best-selling inorganic pigment. However, titanium is a product whose price is subject to large price variations due to product availability. These price increases affect the competitiveness of finished products, and so the search for an alternative to titanium dioxide has generated a variety of possibilities to optimise its use.
Titanium dioxide comes in the form of a white powder and is sometimes used in cosmetics to adjust a color to a lighter shade. This is also why it can produce a white cast.

This was mostly due to the adequate pushback from the supply-demand imbalance, which was further compounded by rising natural gas prices, which had taken a proper toll on the future production of numerous minerals, including titanium dioxide. An increase in COVID instances had prompted concerns in ore feedstock. As a result, during the fourth quarter of 2021, the FD UGSC (USA) quarterly average negotiations for the chemical CP Rutile Grade were finalised at USD 4434 per tonne.
Lithopone is a white pigment (PW5) co-precipitated from solutions of zinc and barium salts according to the following reaction:
Moreover, a 2019 study noted that food-grade titanium dioxide was larger and not nanoparticles. Hence, the authors concluded that any titanium dioxide in food is absorbed poorly, posing no risk to human health (3Trusted Source).
Others focus on producing coated calcium carbonate, where the particles are coated with stearic acid or other substances to enhance dispersion and performance in applications like adhesives and sealants Others focus on producing coated calcium carbonate, where the particles are coated with stearic acid or other substances to enhance dispersion and performance in applications like adhesives and sealantsclassification of calcium carbonate factory.Other scientists, however, have called into question the experimental designs of such studies, citing inconsistent results specifically in studies used to test DNA damage.
A 2016 review by the European Food Safety Authority concluded that titanium dioxide absorption is extremely low and any absorbed particles are mostly excreted through feces (17Trusted Source).
CSPI’s Chemical Cuisine is the web’s definitive rating of the chemicals used to preserve foods and affect their taste, texture, or appearance. Besides titanium dioxide, the group recommends avoiding artificial sweeteners like aspartame, acesulfame potassium, and sucralose, as well as synthetic food dyes like Yellow 5 and Red 3. CSPI and others have recently asked the Food and Drug Administration to ban the latter dye in foods and ingested drugs because the FDA has already determined that it is a carcinogen unsafe for use in cosmetics.
