When it comes to sourcing titanium dioxide, it is essential to understand the various processes involved in its production. The two primary production methods are the sulfate process and the chloride process. The sulfate process tends to be more cost-effective in certain contexts, but it also generates a substantial amount of waste, putting pressure on manufacturers to invest in waste treatment technologies. On the other hand, the chloride process is known for its superior quality and lower environmental impact, albeit at a higher production cost.

The particle size and shape of anatase TiO2 play a crucial role in its performance in various applicationschina anatase type titanium dioxide 996. Chinese manufacturers offer a range of particle sizes, including ultrafine particles for superior optical properties and coarser particles for applications requiring higher bulk density. The particles are typically spherical or near-spherical in shape, which enhances their flowability and dispersibility.

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.
