What exactly is titanium dioxide?



tio2 used in paper supplier. TiO2 has the ability to absorb and reflect harmful ultraviolet (UV) radiation, which can cause paper to yellow and degrade over time. By incorporating TiO2 into paper products, paper suppliers can enhance their durability and longevity, ensuring that they remain looking fresh and vibrant for longer periods. This is particularly important for archival papers and documents that need to be preserved for generations.
The Scientific Committee on Consumer Safety (SCCS) warns against sprayable products and powders that may expose users’ lungs to titanium dioxide through inhalation (10).
Inflammation of the intestines
Furthermore, this packaging has been shown to have both antibacterial and photocatalytic activity, the latter of which reduces ultraviolet (UV) exposure (5Trusted Source, 6).
EFSA’s scientific advice will be used by risk managers (the European Commission, Member States) to inform any decisions they take on possible regulatory actions.
lithopone supplier 30% is the perfect solution for partial substitution of TiO2 in fillers due to its very soft nature and hardly any shrinkage properties.

1. What is titanium dioxide?
Variations of titanium dioxide are added to enhance the whiteness of paint, plastics, and paper products, though these variations differ from the food-grade ones for things we eat (1Trusted Source, 2Trusted Source).
In vitro, in the hemocytes of the marine mussel Mytilus hemocytes, suspension of TiO2 NPs (Degussa P25, 10 μg/ml) stimulated immune and inflammatory responses, such as lysozyme release, oxidative burst and nitric oxide production. Vevers and Jha demonstrated the intrinsic genotoxic and cytotoxic potential of TiO2 NPs on a fish-cell line derived from rainbow-trout gonadal tissue (RTG-2 cells) after 24 h of exposure to 50 μg/ml. Reeves et al. demonstrated a significant increase in the level of oxidative DNA damage in goldfish cells, and suggested that damage could not repaired by DNA repair mechanisms. Another suggestion from the mentioned study was that hydroxyl radicals are generated also in the absence of UV light. It has been shown that fish cells are generally more susceptible to toxic/oxidative injury than mammalian cells.
