Both P25TiO2NPs (with or without vitamin B2) were not found beyond the epidermis in 99% of the analyzed TEM images (Fig. 8). This is coherent with previous findings showing that nanoparticles greater than 50 nm can not penetrate the skin, even in vivo models with movement, stretching, and friction [54]. However, in one of the zones, a few nanoparticles were observed inside a hair follicle. This could be due to the follicle exposure after the localized rupture of this physical barrier when rats were shaved in order to clean the area for cream topical administration. This finding suggests that nanoparticle-based sunscreen should not be applied on recently shaved or harmed skin, in order to avoid nanoparticle skin penetration.

Anatase, on the other hand, has an orthorhombic crystal structure and a lower refractive index than rutile. Despite these differences, anatase also possesses excellent photocatalytic properties, making it a promising material for environmental applications such as water treatment and air purification. In addition, anatase's higher surface area and reactivity make it suitable for use in cosmetics, sunscreens, and other personal care products.

TiO2 comes in many different forms. However, only a few of these forms are considered food-grade (acceptable to be added to food). Many studies that raised concern about the safety of TiO2, including the concern for genotoxicity, used forms of TiO2 that are not considered acceptable for use in food and have different properties than food-grade TiO2. Other studies did use food-grade TiO2, but took steps to break the material down into smaller particles than what would normally be found in food.

  • In the vast and dynamic landscape of global industry, China has carved out a niche for itself as a leader in manufacturing and production. One such example is found within the realm of lithopone, a vital component used extensively in paints, plastics, and other industrial applications. The quality of Chinese lithopone, often underscored by its consistency and reliability, is a reflection of the nation's commitment to innovation and sustainability.
  • Some of the leading players in the rutile market factory industry include Rio Tinto, Iluka Resources, Tronox, and Cristal Global. These companies have extensive experience in the extraction, processing, and marketing of rutile, and they continue to invest in research and development to improve their processes and products.
