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.

  • As we have seen, titanium dioxide is a multifaceted material with a diverse range of applications. From enhancing the aesthetic appeal of products to contributing to groundbreaking medical research and environmental remediation, this compound continues to play a crucial role in modern technology and industry. Its versatility and efficacy have solidified titanium dioxide's position as an indispensable resource in our quest for innovation and improvement across various sectors.

  • The pricing of lithopone pigments can fluctuate based on several factors, including raw material costs, production processes, and market demand. Typically, wholesale prices reflect the bulk purchasing power, enabling businesses to acquire these materials at a lower cost per unit. Over the years, the market has seen fluctuations in prices due to changes in the supply chain and global economic conditions. It is crucial for buyers to stay informed about these trends to budget effectively and maintain profitability.


  • To ensure the optimal precipitation percentage, it is important to carefully control these factors during the precipitation process. For example, a higher concentration of titanium sulfate will typically result in a higher precipitation percentage, but may also lead to the formation of impurities. On the other hand, a lower pH of the reaction mixture can promote the precipitation of titanium hydroxide, but may also result in a lower precipitation percentage.

  • Lithopone B301, Lithopone B311 powder, brilliant white pigment used in paints, inks, leather, paper, linoleum, and face powder. It was developed in the 1870s as a substitute or supplement for lead carbonate (white lead), to overcome its drawbacks of toxicity, poor weathering, and darkening in atmospheres that contain sulfur compounds. Lithopone B301, Lithopone B311 powder is an insoluble mixture of barium sulfate and zinc sulfide that precipitates upon mixing solutions of barium sulfide and zinc sulfate. The precipitate is recovered by filtration, then calcined (roasted) at temperatures above 600° C (1,112° F). Although Lithopone B301, Lithopone B311 powder has been replaced in many applications by titanium dioxide, it is still widely used in a number of products, such as water paints.

  • The demand for transparent TiO2 has been steadily increasing as manufacturers seek to develop products with improved aesthetics and functionality
  • One of the key factors to consider when choosing a supplier for brilliant blue FCF and titanium dioxide is the quality of their products. Suppliers should provide detailed information about the purity and composition of their dyes and pigments, as well as any potential impurities or contaminants that may be present. Additionally, suppliers should have proper documentation and certifications to demonstrate the safety and compliance of their products.
  • During the calcination process, impurities are removed, and the zinc sulfide particles are transformed into a fine powder. The resulting powder is then subjected to rigorous grinding and classification to achieve the desired particle size distribution and morphology. This step is crucial for ensuring that the final product meets the strict requirements of various applications.

  • Now imagine the delicate skin on your face, on your children’s arms & legs. Each day un-knowingly, thinking we are doing the right thing, we slather them up with titanium dioxide in the form of sunscreen & send them out into the sun, all the while never knowing that once exposed to light titanium dioxide creates free radicals that are strong enough to damage steel roofing panels!!

  • In recent years, there has been a growing demand for lithopone in the global market, driven by the increasing use of the pigment in various industries, such as construction, automotive, and packaging. This has led to a rise in the number of factories producing lithopone, particularly in China, where the majority of the pigment is manufactured.
  • Looking ahead, the price of titanium dioxide per ton is expected to be influenced by several factors. Firstly, the ongoing expansion of the e-commerce industry is likely to drive demand for packaging materials that use titanium dioxide, such as plastics and paper. This could lead to increased demand and potentially higher prices. Secondly, the development of new technologies, such as solar energy and electric vehicles, may create new applications for titanium dioxide, further driving demand and prices. Finally, geopolitical tensions and trade policies could also impact the price of titanium dioxide per ton by affecting the availability and cost of raw materials and the competitiveness of global markets.

  • After the mixing, the concrete is poured into molds or forms, where it undergoes a curing processtio2 concrete factory. During this stage, the TiO2-infused concrete gains strength and stability. The curing conditions, including temperature and humidity, are closely monitored to optimize the properties of the final product.

  • In addition to hiding power, titanium dioxide also plays a vital role in enhancing the durability of paints. It acts as a barrier, protecting the walls from external elements such as UV radiation, moisture and pollutants. Titanium dioxide's high refractive index allows it to reflect harmful UV rays, preventing them from fading paint and retaining its vibrant colors for a long time. This UV resistance is especially important for facades that are exposed to sunlight throughout the day.
