The gastrointestinal tract is a complex barrier/exchange system, and is the most important route by which macromolecules can enter the body. The main absorption takes place through villi and microvilli of the epithelium of the small and large intestines, which have an overall surface of about 200 m2. Already in 1922, it was recognized by Kumagai, that particles can translocate from the lumen of the intestinal tract via aggregation of intestinal lymphatic tissue (Peyer’s patch, containing M-cells (phagocytic enterocytes)). Uptake can also occur via the normal intestinal enterocytes. Solid particles, once in the sub-mucosal tissue, are able to enter both the lymphatic and blood circulation.
For this reason alone, its time to ditch the Titanium Dioxide & give your skin a break from the relentless free radical damage.
“Unlike some other chemicals used in food, titanium dioxide has no nutritive, preservative, or food safety function—its use is purely cosmetic,” said CSPI principal scientist for additives and supplements, Thomas Galligan. “The prospect of titanium dioxide nanoparticles damaging DNA is concerning enough for us to recommend consumers avoid foods that have it.”
Despite its many benefits, discussions around titanium dioxide are not without controversy. Concerns about nanoparticles and their potential health effects when used in sunscreens or other products have prompted research into its safety at these microscopic scales. As with many advances in science, balancing the innovation titanium dioxide brings against the need for rigorous safety assessments is crucial.
As for titanium dioxide, the FDA approved titanium dioxide for use as a food additive in 1966. The last time the agency reviewed the additive’s safety, according to the Guardian, was in 1973.
The assessment was conducted following a rigorous methodology and taking into consideration many thousands of studies that have become available since EFSA’s previous assessment in 2016, including new scientific evidence and data on nanoparticles.
ConclusionThere are numerous manufacturers of titanium dioxide; the largest include Delaware-based Chemours (a spin-off of DuPont Chemical), Texas-based Kronos, and China-based Lomon Billions Group, all of which manufacture pigments for use in products like paints, coatings, and plastics. UK-based Venator is a major supplier of titanium dioxide used in food and cosmetics, along with paints, paper, plastic, and more. As a pigment, it is called Pigment White 6 (PW6), titanium white, or CI 77891. As a food additive, it is known as E171.
The global lithopone pigment market is driven by the growth of end-use industries, particularly construction and automotive, where coatings and plastics play a significant role. Manufacturers are constantly innovating to improve the quality of lithopone pigments, focusing on enhancing their whiteness, opacity, and weather resistance. Environmental concerns have also led to the development of eco-friendly production methods, reducing waste and minimizing the environmental footprint. Another critical aspect is logistics; given the vast geographical expanse of China, suppliers with efficient distribution networks can ensure timely delivery, reducing potential delays in construction schedules
Importantly, TiO2 also has a very high refractive index (its ability to scatter light), even higher than diamond. This makes it an incredibly bright substance and an ideal material for aesthetic design use.
In terms of refractive index and opacity, lithopone surpasses zinc oxide and lead oxide. Lithopone's high refractive index allows it to efficiently scatter and reflect light, thereby increasing the opacity of various media. Whether you need to enhance the opacity of paints, inks or plastics, lithopones deliver outstanding results, ensuring your final product is completely opaque.
Lithopone, a staple in the paint industry, boasts a unique blend of properties that make it an indispensable component for achieving high-quality finishes. Among its many variants, B301 and B311 stand out as two of the most sought-after types due to their specific characteristics and performance metrics. In this brief exploration, we will delve into the significance of these lithopone grades, discuss factors affecting their price lists, and highlight the role of reputable suppliers in ensuring consistent quality and availability. In conclusion, the R-906 grade of rutile titanium dioxide plays a pivotal role in enhancing the grade of printing inks. Its exceptional optical properties, combined with its chemical and physical stability, make it an indispensable component for achieving superior print quality. As the demand for high-performance printing solutions continues to grow, suppliers who prioritize using R-906 rutile titanium dioxide will undoubtedly remain at the forefront of the industry, providing clients with inks that stand the test of time and the elements.
The whole scientific experimental design in some of these studies is very flawed, Kaminski said.
