The precipitation of titanium dioxide is a crucial process in the manufacturing of this important industrial material. Titanium dioxide is a white pigment that is widely used in various industries, such as paints, coatings, plastics, and cosmetics, due to its excellent opacity, brightness, and UV resistance.
It’s particularly useful in sunscreen as it has impressive UV resistance and helps block the sun’s UVA and UVB rays from reaching your skin (6Trusted Source).
Understanding Gravimetric Analysis
TiO2 is typically thought of as being chemically inert, meaning it does not react with other chemicals and is, therefore, a stable substance that can be used in many different industries and for various applications.
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].
Challenges and Innovations
A 2016 review by the European Food Safety Authority concluded that titanium dioxide absorption is extremely low and any absorbed particles are mostly excreted through feces (17Trusted Source).
Mixed crystal nano titania, a revolutionary materialMixed crystal nano titania, a revolutionary materialtechnology, has been has been gaining significant attention due to its unique properties and potential applications. This innovative substance is composed of titanium dioxide (TiO2) nanoparticles that are mixed with other materials to create a composite structure. The resulting material exhibits enhanced optical, electronic, and catalytic properties, making it an ideal candidate for various industrial and technological applications.Titanium dioxide can boost and brighten colors because of how well it absorbs and also scatters light. In food and drugs, this additive is known as E171 and helps define colors clearly and can prevent degradation (cracking and breakdown of materials) from exposure to sunlight.
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.
