FDA’s response

Packaging containing this additive has been shown to decrease ethylene production in fruit, thus delaying the ripening process and prolonging shelf life (4Trusted Source).
Regarding flavoring substances, JECFA concluded that there is no safety concern and established specifications for 21 agents across three classes: aliphatic primary alcohols, aldehydes, carboxylic acids, acetals, and esters containing additional oxygenated functional groups; linear and branched-chain aliphatic, unsaturated and unconjugated alcohols, aldehydes, acids, and related esters; and saturated aliphatic acyclic linear primary alcohols, aldehydes, and acids.
In addition to its outstanding properties, lithopone has excellent stability, weather resistance and chemical inertness. This makes it suitable for a wide range of applications, even under harsh environmental conditions. You can rely on lithopone to stand the test of time, maintaining its luster and performance for years to come.

Uses
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.
Scientists analyzed research that examined how titanium dioxide nanoparticles interact with the brain for a 2015 review published in Nanoscale Research Letters. The researchers wrote: “Once the TiO2 NPs are translocated into the central nervous system through [certain] pathways, they may accumulate in the brain regions. For their slow elimination rates, those NPs could remain in the brain zones for a long period, and the Ti contents would gradually increase with repeated exposure.” After reviewing dozens of studies, the scientists concluded: “Long-term or chronic exposure to TiO2 nanoparticles could potentially lead to the gradually increased Ti contents in the brain, which may eventually induce impairments on the neurons and glial cells and lead to CNS dysfunction as a consequence.”
Moreover, lithopone suppliers are expanding their product lines to offer variations of the pigment that meet specific market needs. Some suppliers provide specialized grades of lithopone that are tailored for particular applications, such as high gloss paints or specialty coatings. By offering these tailored solutions, suppliers can help paint manufacturers enhance the performance characteristics of their products, thus gaining a competitive edge in the market.

In food products, E171 is not a singular ingredient; it’s always combined with other ingredients (e.g., proteins and fats) in the food product. Digesting food is a slow process for the body compared to drinking a beverage, which passes much faster through the body.
