The utilization of Titanium Dioxide (TiO2) has been a significant focus in various industries due to its exceptional properties and broad range of applications. TiO2, a naturally occurring oxide of titanium, is known for its high refractive index, strong photocatalytic activity, and excellent UV absorption capabilities.
One of the key benefits of using anatase titanium dioxide in paints is its high opacity and hiding power. This pigment is able to cover imperfections on the substrate and create a smooth and even finish. Additionally, anatase titanium dioxide is resistant to weathering, UV radiation, and chemicals, which ensures the durability and longevity of the paint film.
In conclusion, suppliers of 30-50nm TiO2 powders play an instrumental part in advancing technological frontiers. Their ability to provide high-quality, consistent, and responsibly sourced materials is vital for driving innovation across multiple sectors. As research continues to unlock new potential uses for these remarkable nanoparticles, the partnership between industry and supplier will be essential for translating scientific breakthroughs into practical solutions that benefit society.
The aim of this work was to examine particularly the Degussa P25 titanium dioxide nanoparticles (P25TiO2NPs) because they are among the most employed ones in cosmetics. In fact, all kinds of titanium dioxide nanoparticles (TiO2NPs) have gained widespread commercialization over recent decades. This white pigment (TiO2NPs) is used in a broad range of applications, including food, personal care products (toothpaste, lotions, sunscreens, face creams), drugs, plastics, ceramics, and paints. The original source is abundant in Earth as a chemically inert amphoteric oxide, which is thermally stable, corrosion-resistant, and water-insoluble. This oxide is found in three different forms: rutile (the most stable and substantial form), brookite (rhombohedral), and anatase (tetragonal as rutile), of these, both rutile and anatase are of significant commercial importance in a wide range of applications [3]. Additionally, the nano-sized oxide exhibits interesting physical properties, one of them is the ability to act as semiconducting material under UV exposure. In fact, TiO2NPs are the most well-known and useful photocatalytic material, because of their relatively low price and photo-stability [4]. Although, this photoactivity could also cause undesired molecular damage in biological tissues and needs to be urgently assessed, due to their worldwide use. However, not all nanosized titanium dioxide have the same behavior. In 2007, Rampaul A and Parkin I questioned: “whether the anatase/rutile crystal form of titanium dioxide with an organosilane or dimethicone coat, a common titania type identified in sunscreens, is appropriate to use in sunscreen lotions” [5]. They also suggested that with further study, other types of functionalized titanium dioxide could potentially be safer alternatives. Later, Damiani found that the anatase form of TiO2NPs was the more photoactive one, and stated that it should be avoided for sunscreen formulations, in agreement with Barker and Branch (2008) [6,7].

Properties:
Lithopone is the ideal combination of the white pigment zinc sulfide and the white spacer Blanc fixe. Due to the particle distribution of the ZnS (0.35 µm) and BaSO4 (0.8 -1.0 µm), which is the result of a co-precipitation (not mixing) and co-calcination, a high packing density is achieved, which in turn gives Lithopone its low resin demand and excellent rheological properties.
