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].

However, it is important to note that while mica and titanium dioxide can be beneficial in shampoo, they may not be suitable for everyone. Some individuals may experience allergic reactions or irritation when using products containing these minerals, especially if they have sensitive skin or hair. Therefore, it is always advisable to conduct a patch test before using any new product, especially if you have never used mica or titanium dioxide before.

Another advantage of mixed crystal nano titania is its improved mechanical strength and durability. When combined with other materials, such as metals or polymers, the resulting composite exhibits superior resistance to wear and tear, making it suitable for use in harsh environments When combined with other materials, such as metals or polymers, the resulting composite exhibits superior resistance to wear and tear, making it suitable for use in harsh environments When combined with other materials, such as metals or polymers, the resulting composite exhibits superior resistance to wear and tear, making it suitable for use in harsh environments When combined with other materials, such as metals or polymers, the resulting composite exhibits superior resistance to wear and tear, making it suitable for use in harsh environmentsmixed crystal nano titania. This property also extends to its thermal stability, allowing it to maintain its structural integrity at high temperatures without undergoing phase transitions or degradation.
