In a 2020 study published in the Journal of Trace Elements in Medicine and Biology, researchers conducted an in vitro experiment to analyze the effects of TiO2 nanoparticles on a human neuroblastoma (SH-SY5Y) cell line. The scientists evaluated “reactive oxygen species (ROS) generation, apoptosis, cellular antioxidant response, endoplasmic reticulum stress and autophagy.” The results showed that exposure to the nanoparticles “induced ROS generation in a dose dependent manner, with values reaching up to 10 fold those of controls. Nrf2 nuclear localization and autophagy also increased in a dose dependent manner. Apoptosis increased by 4- to 10-fold compared to the control group, depending on the dose employed.” 

In order to evaluate the penetration of the nanoparticles, eight adult male Wistar rats (3 months old) were used for the in vivo experiments. The protocol was approved by the local University Committee for animal testing and is in accordance with the Canadian Council on Animal Care (CICUAL-RD-2021–892-E-UNC-DEC#FCQ).

In addition to its pharmaceutical applications, barium sulphate is extensively utilized in the production of paints and coatings, where a bright white pigment is essential. The opacity and brightness provided by barium sulphate make it a popular choice in formulations for white and colored paints. Its non-toxic nature and excellent stability enhance its appeal in these products.

Titanium dioxide manufacturer: Billions

Another important property of Chinese anatase titanium dioxide is its photocatalytic activity, which enables it to break down organic pollutants and harmful chemicals when exposed to light. This makes it an attractive choice for applications in environmental remediation, such as air and water purification systems. Additionally, its photocatalytic properties have also been studied for use in self-cleaning surfaces, such as windows and building facades, where it can help to reduce maintenance costs and keep surfaces looking clean.

Titanium dioxide is used in an enormous range of food products, which can feel jarring when looking at some of its other uses.

Still many experts say the body of research does not support the current health concerns being expressed about titanium dioxide.

The annual production capacity of high-grade rutile titanium dioxide has reached more than 400,000 tons. It is one of the largest TiO2 manufacturers in China at present. It has more than ten product brands of Taiohua, Jinxing and other brands, and its products are sold in more than 50 countries and regions around the world. It has long maintained the excellent performance of the second overall ranking in the domestic titanium dioxide industry.

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.

Additionally, market demand plays a significant role in determining lithopone pigment prices. Industries such as construction, automotive, and consumer goods have been experiencing fluctuations in demand, influencing the pricing dynamics. In periods of high demand, prices may increase as suppliers adjust to the market trends. Conversely, during downturns or oversupply situations, prices may decrease, providing opportunities for buyers to purchase at more favorable rates.
