The Scientific Facts
Lithopone 30% CAS No. 1345-05-7 / Application
The raw material used in this method is FeSO4. In order to maintain the Fe3 + concentration in the reaction medium in a specific range, reducing agent iron sheet is added in the reaction process. Iron yellow crystal seed was added and air was introduced to synthesize iron yellow under certain pH conditions. The method mainly includes two steps: (1) firstly, FeSO4 · 7H2O is used as raw material, NaOH or NH3 · H2O is used as precipitant or pH regulator, and air is used as oxidant to prepare crystal seed; (2) Iron yellow is produced by two-step oxidation with crystal seed, FeSO4, iron sheet and air.
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!
All food businesses currently using titanium dioxide as a food additive have a legal responsibility to comply with the requirements of Regulation (EU) 2022/63, banning the use of titanium dioxide. The FSAI encourages food businesses to source suitable alternatives to titanium dioxide and start the process of reformulation now to ensure compliance in advance of the ban coming into force on 7 August 2022.


Titanium dioxide (TiO2) is a versatile and widely used inorganic compound that has numerous applications, ranging from pigments in paints and coatings to cosmetics and pharmaceuticals. As a result, the demand for TiO2 powder suppliers has been steadily increasing.

Overall, the Food Directorate's comprehensive review of the available science of TiO2 as a food additive showed:
