tio2 technology manufacturer
In terms of production, China is the largest producer of both calcium carbonate and titanium dioxide in the world. The country has abundant reserves of both minerals and a well-developed mining and processing industry

china calcium carbonate vs titanium dioxide. China's calcium carbonate production is concentrated in regions such as Guangdong, Guangxi, and Jiangsu, while titanium dioxide production is centered in provinces such as Shandong, Henan, and Sichuan.
In recent years, the manufacturing industry has come under scrutiny for its environmental impact. The production process of titanium dioxide is no exception. Traditional methods often involve energy-intensive procedures and the use of chemicals that can pose risks to both human health and the environment. As awareness grows about these issues, manufacturers are compelled to reevaluate their processes and adopt more eco-friendly techniques.
Friends of the Earth revealed new testing results from the Australian Government’s National Measurement Institute, which found that many popular sunscreen and cosmetic products are using a potentially hazardous form -- anatase titanium dioxide. Six of the eight products tested, including well-known brands such as Nivea, L'Oreal, and CoverGirl, were found to contain this ingredient. (2)
The additives that received a “no safety concern” conclusion based on current estimated dietary exposure are as follows:
Other food products that list titanium dioxide are Lucerne cottage cheese, Beyond Meat's chicken plant-based tenders, Great Value ice cream and Chips Ahoy! cookies.

Infrared analysis showed that the characteristics bands for the bare nanoparticles are still exhibited in the vitamins@P25TiO2NPs spectra, such as a wide peak in 450–1028 cm−1 related to the stretching vibration of Ti-O-Ti and other peaks in 1630 cm−1 and 3400 cm−1, which represent the surface OH groups stretching. The IR spectrum of vitaminB2@P25TiO2NPs showed signs of binding between compounds. The OH bending peak (1634 cm−1) corresponding to bare nanoparticles disappeared, and the NH2 bending band characteristic of vitamin B2 appeared (1650 cm−1). The IR spectrum of vitaminC@P25TiO2NPs also showed signs of successful functionalization. Bands at 1075 cm−1; 1120 cm−1; 1141 cm−1 were observed, which are originated by C
O-C vibrations present in the vitamin C. The intense band at 1672 cm−1 is attributed to the C = O stretching in the lactone ring while the peak at 1026 cm−1 is ascribed to the stretching vibration Ti-O-C. Wide bands at 3880–3600 cm−1 are related to stretching vibration OH groups, but those disappear in the modified nanoparticles spectrum. These observations confirm the interactions between the P25TiO2NPs and the vitamins [35].
