1. Versatility Both Ponceau 4R and titanium dioxide are highly versatile ingredients that can be used in a wide range of cosmetic products.
The National Cancer Institute tested TiO2 for possible carcinogenicity by the oral route of exposure by feeding rats and mice with TiO2 (size not specified) at doses 25,000 or 50,000 ppm TiO2 for 103 weeks. They concluded that TiO2 was not carcinogenic.Also, the study with rats fed diets containing up to 5 % TiO2 coated mica for 130 weeks showed no treatment-related carcinogenicity. Since the size and other TiO2 properties were not specified or determined, we cannot generalize this conclusion and we have to take into account other possible outcomes of this scenario in different exposure conditions (other size/crystalline structure of TiO2 etc.).
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.
Titanium Dioxide: E171 no longer considered safe when used as a food additive by European Food Safety Authority, May 6, 2021
Ensuring Safety in the Wholesale TiO2 Industry
One of the key advantages of TR 28 titanium dioxide is its ability to enhance the performance of products in which it is used. Its high refractive index allows it to scatter light effectively, resulting in brighter colors and improved opacity Its high refractive index allows it to scatter light effectively, resulting in brighter colors and improved opacity

One of the key factors contributing to China's success in this sector is its well-developed infrastructure and logistics network. The country's extensive railway system, ports, and highways facilitate the transportation of raw materials and finished products efficiently, reducing costs and improving overall efficiency. Additionally, China's commitment to technological innovation has led to the development of advanced production techniques and equipment, further enhancing its competitiveness in the global market.
