In an early study Jani et al. administred rutile TiO2 (500 nm) as a 0.1 ml of 2.5 % w/v suspension (12.5 mg/kg BW) to female Sprague Dawley rats, by oral gavage daily for 10 days and detected presence of particles in all the major gut associated lymphoid tissue as well as in distant organs such as the liver, spleen, lung and peritoneal tissue, but not in heart and kidney. The distribution and toxicity of nano- (25 nm, 80 nm) and submicron-sized (155 nm) TiO2 particles were evaluated in mice administered a large, single, oral dosing (5 g/kg BW) by gavage. In the animals that were sacrificed two weeks later, ICP-MS analysis showed that the particles were retained mainly in liver, spleen, kidney, and lung tissues, indicating that they can be transported to other tissues and organs after uptake by the gastrointestinal tract. Interestingly, although an extremely high dose was administrated, no acute toxicity was observed. In groups exposed to 80 nm and 155 nm particles, histopathological changes were observed in the liver, kidney and in the brain. The biochemical serum parameters also indicated liver, kidney and cardiovascular damage and were higher in mice treated with nano-sized (25 or 80 nm) TiO2 compared to submicron-sized (155 nm) TiO2. However, the main weaknesses of this study are the use of extremely high single dose and insufficient characterisation of the particles.

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

In a coatings factory, the production process involving TiO2 begins with its careful incorporation into the formulation. The pigment is mixed with other ingredients like binders, solvents, and additives to create a homogeneous mixture. This mixture is then processed further to obtain the desired consistency and viscosity, suitable for different application methods such as spraying, brushing, or rolling.

 

In the vast and diverse landscape of Chinese culture, the use of lithopone quotes stands as a testament to the enduring power of traditional art forms. Lenticular printing, often referred to as lithopone, is a method that combines images from different angles into one, creating an intriguing optical illusion. In China, this technique has been adapted to showcase famous quotes, blending words with visual artistry to convey deeper meanings and cultural values. In addition to producing TiO2 pigment, some factories also offer custom blending and color matching services to meet the specific requirements of their customers. This allows industries such as paint manufacturers to create unique shades and colors by blending different pigments to achieve the desired results.

In 2022, a year after the EFSA recommended against the use of E171, the Food Standards Australia New Zealand (FSANZ) conducted its own reassessment of titanium dioxide as a food additive. The agency concluded that titanium dioxide was indeed safe to use as a food additive. The United Kingdom and Canada came to similar conclusions.

One of the primary functions of titanium dioxide in plastic manufacturing is its ability to act as a potent ultraviolet (UV) light absorber. By incorporating TiO2 into plastic formulations, manufacturers can create materials that resist discoloration and degradation caused by exposure to sunlight and other sources of UV radiation. This not only extends the lifespan of the final product but also maintains its aesthetic appeal over time, making it especially valuable for outdoor applications such as gardening tools, outdoor furniture, and automotive parts.

Titanium dioxide is a white pigment that is commonly used in plastic manufacturing to provide opacity, brightness, and UV protection. It is also widely utilized in the dyeing industry to enhance color intensity and durability. R218 factory specializes in producing high-quality titanium dioxide that meets the stringent requirements of these industries. Titanium Dioxide (TiO2), a versatile and highly effective pigment, plays an indispensable role in the production process of nitrile gloves, a staple in various industries due to their durability and chemical resistance. As a leading material in the manufacturing sector, nitrile gloves factories have increasingly incorporated titanium dioxide into their production lines to enhance the quality and performance of their products. The production of lithopone is associated with several environmental concerns, including air and water pollution. Zinc sulfide ore mining can lead to soil erosion and habitat destruction, while sulfuric acid leaching and calcination processes can release pollutants into the air and water. To address these issues, many Chinese lithopone factories have implemented environmental protection measures such as wastewater treatment and emission reduction technologies.

    Prof. Maged Younes, Chair of EFSA’s expert Panel on Food Additives and Flavourings (FAF), wrote of the decision: “Taking into account all available scientific studies and data, the Panel concluded that titanium dioxide can no longer be considered safe as a food additive. A critical element in reaching this conclusion is that we could not exclude genotoxicity concerns after consumption of titanium dioxide particles. After oral ingestion, the absorption of titanium dioxide particles is low, however they can accumulate in the body.”

    One of the key players in the Chinese titanium dioxide industry is the China Titanium Dioxide Plant. This state-of-the-art facility is equipped with the latest technology and machinery to produce high-quality titanium dioxide products. The plant is strategically located in a region with abundant titanium resources, allowing for cost-effective production and efficient supply chain management. Environmental considerations are also paramount in the production and supply of titanium dioxide. Manufacturers and suppliers are increasingly adopting greener technologies and practices to reduce the environmental footprint associated with mining, refining, and transportation. Efforts include improving energy efficiency in the production processes, implementing waste recovery systems, and exploring alternative sources of titanium that minimize ecological disruption.

    So what does this have to do with you?

    Different dermal cell types have been reported to differ in their sensitivity to nano-sized TiO2 . Kiss et al. exposed human keratinocytes (HaCaT), human dermal fibroblast cells, sebaceous gland cells (SZ95) and primary human melanocytes to 9 nm-sized TiO2 particles at concentrations from 0.15 to 15 μg/cm2 for up to 4 days. The particles were detected in the cytoplasm and perinuclear region in fibroblasts and melanocytes, but not in kerati-nocytes or sebaceous cells. The uptake was associated with an increase in the intracellular Ca2+ concentration. A dose- and time-dependent decrease in cell proliferation was evident in all cell types, whereas in fibroblasts an increase in cell death via apoptosis has also been observed. Anatase TiO2 in 20–100 nm-sized form has been shown to be cytotoxic in mouse L929 fibroblasts. The decrease in cell viability was associated with an increase in the production of ROS and the depletion of glutathione. The particles were internalized and detected within lysosomes. In human keratinocytes exposed for 24 h to non-illuminated, 7 nm-sized anatase TiO2, a cluster analysis of the gene expression revealed that genes involved in the “inflammatory response” and “cell adhesion”, but not those involved in “oxidative stress” and “apoptosis”, were up-regulated. The results suggest that non-illuminated TiO2 particles have no significant impact on ROS-associated oxidative damage, but affect the cell-matrix adhesion in keratinocytes in extracellular matrix remodelling. In human keratinocytes, Kocbek et al. investigated the adverse effects of 25 nm-sized anatase TiO2 (5 and 10 μg/ml) after 3 months of exposure and found no changes in the cell growth and morphology, mitochondrial function and cell cycle distribution. The only change was a larger number of nanotubular intracellular connections in TiO2-exposed cells compared to non-exposed cells. Although the authors proposed that this change may indicate a cellular transformation, the significance of this finding is not clear. On the other hand, Dunford et al. studied the genotoxicity of UV-irradiated TiO2 extracted from sunscreen lotions, and reported severe damage to plasmid and nuclear DNA in human fibroblasts. Manitol (antioxidant) prevented DNA damage, implying that the genotoxicity was mediated by ROS.
