The trend in the production of NPs is likely to lead to increasing amounts of nano-powders in the air, water and soil, which will consequently affect living organisms. Labielle et al. demonstrated that 25 % of Al(OH)3-coated TiO2 particles from sunscreens are dispersed as a stable colloid and become available to microorganisms and filter-feeders, while the remaining 75 % are probably incorporated into geogenic sediments, where they could become available to benthic fauna. Solar UV iradiation may penetrate as far as 20 m in the water column and therefore photo-activate the dispersed particles, which may have an adverse effect on various aquatic organisms.
A safety review conducted by the EFSA in 2021 assessed thousands of studies published on titanium dioxide.

What is titanium dioxide? Why is it used in food products?
Lithopone 30% increases extruder performance and reduces processing costs, improves quality and is suitable for masterbatch for injection of Polyolefins, ABS, Polycarbonate, Polypropylene, Polyethylene, Polystyrene, single layer films, multi-layer films and for white, coloured and filled masterbatch. The combination of Lithopone 30 with TiO2 results in improved mechanical properties including higher elongation values and better impact resistance.
It has strong tinting and hiding power, is resistant to alkali and heat, but will decompose when exposed to acid and darken when exposed to light. It has poor weather resistance and is easy to powder, so it is not suitable for outdoor use. In recent years, it has only been used in low-grade products.
When sourcing lithopone for leather production, suppliers must ensure they are purchasing a high-quality product from reputable manufacturers. Consistency in particle size and composition is crucial to achieving the desired color intensity and durability in the final leather goods. By partnering with trusted lithopone suppliers, leather manufacturers can guarantee the quality and performance of their products to meet the expectations of consumers.
Studies of titanium dioxide as a food additive suggest health dangers
Prof Maged Younes, Chair of EFSA’s expert Panel on Food Additives and Flavourings (FAF), said: “Taking into account all available scientific studies and data, the Panel concluded that titanium dioxide can no longer be considered safe as a food additive . A critical element in reaching this conclusion is that we could not exclude genotoxicity concerns after consumption of titanium dioxide particles. After oral ingestion, the absorption of titanium dioxide particles is low, however they can accumulate in the body”.
In industrial settings, people can be exposed to titanium dioxide through inhalation. Inhalation exposure to titanium dioxide is exceedingly rare for most people.

Australia and New Zealand review of TiO2
Manufacturers of titanium dioxide play a crucial role in meeting the global demand for this versatile substance. They employ advanced manufacturing processes and technologies to produce high-quality titanium dioxide with consistent properties and performance. Many manufacturers also invest in research and development to explore new applications and improve existing products.
This article reviews the uses, benefits, and safety of titanium dioxide.
Furthermore, this packaging has been shown to have both antibacterial and photocatalytic activity, the latter of which reduces ultraviolet (UV) exposure (5Trusted Source, 6).
