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.

Mesh, in the context of sieving, denotes the number of openings in a linear inch of a screen or sieve. A 1250 mesh sieve indicates an incredibly fine mesh size, where particles pass through a sieve with approximately 1250 openings per square inch. This level of fineness is crucial for applications requiring minute particle separation, such as in the production of high-quality powders or ultra-refined materials.

Environmental considerations are paramount in these facilities. Waste management strategies are put in place to minimize the environmental footprint. For instance, waste acids generated during the sulfate process can be treated and reused, reducing both cost and environmental impact. Moreover, energy efficiency is a key focus, with many factories investing in renewable energy sources to power their operations.
