Food additive or carcinogen? The growing list of chemicals banned in EU but used in US, by Mikaela Conley, The Guardian, June 23, 2022
In order to contribute with experimental evidence that could help to achieve a better understanding of the field for future regulation, in the present work, the biocompatibility of commercial P25TiO2NPs (one type of TiO2NPs used in sunscreen formulations) and two novel functionalized P25TiO2NPs were evaluated under solar simulated irradiation. White light, generated by red, blue, and yellow LEDs, together with UV ones, was chosen to simulate the solar spectra. Functionalization of TiO2NPs was made with antioxidant vitamins in order to prevent the expected photo-initiated ROS production when nanoparticles are exposed to the simulated solar spectra. Vitamin B2 (riboflavin) and vitamin C were chosen to carry out the functionalization because they are water-soluble, low-cost, and are a constitutive part of biological processes. In addition, it is known that both have the potential to prevent macromolecular oxidation by ROS [23], [24], [25], [26].


Lomon, one of the leading titanium dioxide manufacturers in China, produces the R996 grade titanium dioxide with purity levels exceeding 99%. This high purity ensures that the pigment provides excellent hiding power and color retention in paints, making it a popular choice for the paint industry.

The authority did not identify a safe amount of titanium dioxide that could be consumed.

When asked about the recent Skittles lawsuit, the FDA said the agency does not comment on pending litigation.
Lithopone 30% CAS No. 1345-05-7 / Application
Introduction
However, some experts and food regulators in other countries disagree – pointing to potential, serious health consequences and rising concerns about the additive. Starting August 7, for example, the use of titanium dioxide in food will be banned in the European Union.


In its 2016 opinion, the ANS Panel recommended new studies be carried out to fill the gaps on possible effects on the reproductive system, which could enable them to set an Acceptable Daily Intake (ADI ). Uncertainty around the characterisation of the material used as the food additive (E 171) was also highlighted, in particular with respect to particle size and particle size distribution of titanium dioxide used as E 171.
Still, you may wonder whether it’s safe for consumption.
What is an exposure route?

Because of health risks, France banned titanium dioxide as a food additive in 2020. Two years later the European Union also banned titanium dioxide as a food additive.
Due to its light-scattering properties, small amounts of titanium dioxide are added to certain foods to enhance their white color or opacity (1Trusted Source, 3Trusted Source).
Lithopone 30% is the perfect solution for partial substitution of TiO2 in fillers due to its very soft nature and hardly any shrinkage properties.



The functions of lithopone in coatings: it is mainly used in water-soluble coatings (water-soluble coatings, wall coatings), blending paint as topcoat (with reasonable high paint adhesion, excellent circulation and long storage capacity), all kinds of methyl cellulose paint (can be applied to wooden furniture such as furniture and small toys) Alkali resistant coatings based on isopropyl titanate vulcanized rubber and polyurethane materials. Also because of its excellent paint adhesion, aging resistance, acid resistance and leveling, for the production of lacquered cloth color pigments look better. It can also be used in electrophoretic coating and optical guiding system software.
