TiO₂ comes in many different forms. However, only a few of these forms are considered food-grade (acceptable to be added to food). Many studies that raised concern about the safety of TiO₂, including the concern for genotoxicity, used forms of TiO₂ that are not considered acceptable for use in food and have different properties than food-grade TiO₂. Other studies did use food-grade TiO₂, but took steps to break the material down into smaller particles than what would normally be found in food.

2. Mentality: the buyer has to prepare goods in advance, and the new order price is slightly less willing to purchase in bulk; Because the seller's inventory is small, the manufacturer has no willingness to reduce the price of sales.Trend: The load of titanium dioxide enterprises is stable, the willingness to ship at low prices is not strong, and the downstream buyers place orders in the early stage to establish inventory, and the short-term supplementary orders after the holiday are less. Anatase titanium dioxide due to the overall volume of the market supply side is less, the space for quotation negotiation is small, and the focus of new orders will move up. It is expected that the titanium dioxide market today just needs to be closed, and the market trading atmosphere is relatively light.

Titanium dioxide is produced in two main forms. The primary form, comprising over 98 percent of total production, is pigment grade titanium dioxide. The pigmentary form makes use of titanium dioxide’s excellent light-scattering properties in applications that require white opacity and brightness. The other form in which titanium dioxide is produced is as an ultrafine (nanomaterial) product. This form is selected when different properties, such as transparency and maximum ultraviolet light absorption, are required, such as in cosmetic sunscreens.

Why is titanium dioxide used in food, including in Skittles?

Above 10%, 1 kg of TiO2 should be replaced by 1.3 kg of Lithopone 30%, reducing the amount of polymer accordingly.
