Wegman’s puts titanium dioxide in its Original Macaroni and Cheese. Campbell’s Healthy Request Chunky Chicken Corn Chowder has it, as does Food Club’s Chunky New England Clam Chowder. Marzetti uses the color agent to brighten its Cream Cheese Fruit Dip. Dairy products usually don’t need titanium dioxide to look white, but Kroger has decided to add titanium dioxide to its Fat Free Half-and-Half. And titanium dioxide isn’t only in especially white or brightly colored foods: Little Debbie adds it to Fudge Rounds and many other products. According to the Food Scores database maintained by Environmental Working Group, more than 1,800 brand-name food products have titanium dioxide on their ingredients list. That said, it can still lurk as an unspecified “artificial color,” or labels might simply say “color added.”

According to the American Chemistry Council, titanium dioxide (TiO2) is an inorganic substance that's used as a white powder in a variety of industrial and consumer goods, including in sunscreen, cosmetics, toothpaste, paint, plastics, food and more.

Lithopone B301

Lithopone is chemically inert and practically insoluble in acids, alkalis and solvents. The optimized particle-size distribution of Lithopone attained by means of co-precipitation and calcining permit the achievement of a high apparent density, which imparts to Lithopone its low resin requirement and its excellent rheological behaviour.
