In conclusion, lithopone is an essential ingredient in the leather industry, providing both aesthetic appeal and practical benefits for leather suppliers. Its ability to create vibrant colors, excellent covering power, cost-effectiveness, and versatility make it a valuable asset in the production of high-quality leather goods. By choosing the right lithopone suppliers and incorporating this pigment into their manufacturing process, leather suppliers can enhance the appeal and durability of their products to meet the demands of the market.

Traditionally, UV-filters are categorized as either chemical or physical. The big difference is supposed to be that chemical agents absorb UV-light while physical agents reflect it like a bunch of mini umbrellas on top of the skin. While this categorization is easy and logical it turns out it's not true. A recent, 2016 study shows that inorganic sunscreens work mostly by absorption, just like chemical filters, and only a little bit by reflection (they do reflect the light in the visible spectrum, but mostly absorb in the UV spectrum).

In short, no, research demonstrates that E171 is safe when consumed in normal situations.

Moreover, how we're exposed to an ingredient matters significantly in terms of our health and potential toxicity.   

Research shows that inhaling titanium dioxide particles in significant quantities over time can cause adverse health outcomes. Unless you work in an industrial setting, inhaling substantial amounts of titanium dioxide is highly unlikely. 

Research supports that applying titanium dioxide to the skin in the form of sunscreens, makeup, and other topical products does not pose a health risk. 

Overwhelmingly, research that's relevant to human exposure shows us that E171 is safe when ingested normally through foods and drugs (1,2).

Again, other research suggests that E171 could cause harm; however, those research processes did not design their studies to model how people are exposed to E171. Research that adds E171 to drinking water, utilizes direct injections, or gives research animals E171 through a feeding apparatus is not replicating typical human exposure, which occurs through food and medicine consumption.

Manufacturers use titanium dioxide in some packaging to protect food from exposure to sunlight. Lab studies show it may also help stop bacteria from growing, and break down a gas that makes many fruits and vegetables ripen faster. That can keep products fresher and give them a longer shelf life.

Often used as a glaze for ceramics, titanium dioxide provides a bright, glossy finish and improves the durability and stain resistance of ceramic products.

One of the most widely used food pigments is titanium dioxide, an odorless powder that enhances the white color or opacity of foods and over-the-counter products, including coffee creamers, candies, sunscreen, and toothpaste (1Trusted Source, 2Trusted Source).
