 With the development of science and technology, various pigments have emerged. Inorganic pigments are facing serious challenges. Nanomaterials are a new class of materials with mesoscopic dimension developed at the end of the 20th century. They are now developing in a low-dimensional and complex direction. . In recent years, nano-Lide powder has been put into industrial production. The zinc sulphate solution is prepared in the same way as the traditional method. In the organic phase (such as benzene), the production cost is high, the wastewater is difficult to recycle, the organic solvent in the production process and the final immersion. Slag is likely to cause environmental pollution, and its development is severely limited.

In a 2017 study published in Scientific Reports, researchers exposed rats to human-relevant levels of E171 to examine the effects of intestinal inflammation and carcinogenesis. They saw that “a 100-day E171 treatment promoted colon microinflammation and initiated preneoplastic lesions while also fostering the growth of aberrant crypt foci in a chemically induced carcinogenesis model.” They continued: “Stimulation of immune cells isolated from Peyer’s Patches [which are clusters of lymphoid follicles found in the intestine] showed a decrease in Thelper (Th)-1 IFN-γ secretion, while splenic Th1/Th17 inflammatory responses sharply increased,” researchers wrote. “A 100-day titanium dioxide treatment promoted colon microinflammation and initiated preneoplastic lesions.” The scientists concluded: “These data should be considered for risk assessments of the susceptibility to Th17-driven autoimmune diseases and to colorectal cancer in humans exposed to TiO2 from dietary sources.”
