On the other hand, the U.S. Food and Drug Administration (FDA) in their Final Administrative Order on Sunscreen Drug Products posted in September 2021 still accepts titanium dioxide up to 25% in the list of Generally Recognized As Safe and Effective (GRASE) in the main document, without further clarification on what kind or size of particles [9]. However, on page 24 (Sunscreen containing nanomaterials) FDA clearly “distinguish nanomaterials from other forms of these ingredients'' (zinc oxide and titanium dioxide) and ask for comments on “any particular nanomaterials that you believe should not be permitted for use in OTC sunscreen products”. To the best of our knowledge, this Agency did not ban the use of nanoparticulate titanium dioxide in any form, even though it is mentioned on page 34 that the anatase form is the more photoactive one, due to the lack of evidence with real sunscreens OTC (over the counter) in vivo. Moreover, other regulations in Latin America (MERCOSUR agreement, 2006) do not state clearly their position on the use of nanoparticulate TiO2NPs [10].

Another important factor to consider is the manufacturer's production capacity and lead times

best price titanium dioxide manufacturer. A manufacturer with a large production capacity can quickly fulfill large orders, while shorter lead times ensure timely delivery. This is particularly important for businesses with tight production schedules or those in need of titanium dioxide for time-sensitive projects.

Titanium dioxide, a naturally occurring oxide of titanium, is known for its exceptional opacity, whiteness, and brightness. It serves as a pigment in coatings, providing superior color stability, durability, and UV resistance. This makes it ideal for use in exterior coatings where protection against sunlight-induced degradation is crucial.

Below are selected applications of photocatalytic pollutant decomposition processes on titanium oxide:
1. Self-cleaning surfaces: for the production of glass for spotlights, traffic lights, car mirrors, window panes, for road paints, for covering sound-absorbing screens and tunnel walls.
2. Air cleaning and odor removal: filters that are used in enclosed spaces (e.g. public toilets) or filters for air-conditioning equipment.
3. Water treatment: groundwater treatment installations, water purification installations in the intakes of drinking water from rivers.
4. Self-disinfecting materials: towels, linings, clothing, equipment in hospitals, wall surfaces of operating rooms.
5. Removal of lesions: anti-cancer therapy.
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 CO-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].
