4. Cost-Effectiveness Purchasing titanium dioxide in wholesale quantities can lead to significant cost savings for tire manufacturers. By acquiring TiO2 in bulk, manufacturers can reduce production costs per unit, thereby improving their profit margins. Moreover, the durability and performance enhancements associated with TiO2 help reduce the frequency of tire replacements, further amplifying cost efficiency.

It’s also used in food products to provide a white color. Candies, cakes and creamers are examples of foods that may contain titanium dioxide for its color enhancing and bleaching properties.

While Skittles don't include white in their line-up, Dr. Johnson-Arbor theorizes that titanium dioxide is used to help contain all the other beautiful colors.
