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.

  • There seems to be a lot of misunderstanding about titanium dioxide, which can be used as a colorant in foods. While headlines may suggest titanium dioxide is a health concern, scientific research has actually shown titanium dioxide to be safe. So what is it used for and why is it used? Read on to learn more!

  • Secondly, the supplier's technical expertise and ability to provide technical support are also crucial factors. Ceramic manufacturers may face various challenges during the production process, such as issues with color consistency or glaze application. A supplier with strong technical capabilities can offer valuable advice and assistance to help resolve these issues.
  • As the demand for anatase products continues to grow, the number of factories specializing in their production is also expected to increase. Furthermore, ongoing research and development efforts are aimed at improving the performance and functionality of anatase products, expanding their applications and making them more accessible to a wider range of industries.
  • Because of the uncertainty of the impacts of nanoparticles, Made Safe exercises the precautionary principle, meaning we avoid nanoparticles until more extensive scientific testing proves their safety.
