- Production Process
- The pigment lithopone industry has undergone a significant transformation over the past century, with factories playing a crucial role in the production and distribution of this essential compound. Lithopone, a vital component in various industries such as paints, plastics, and printing inks, is a fine white powder consisting of a mixture of zinc sulfide and barium sulfate. This article will explore the evolution of pigment lithopone factories, their impact on the global market, and future prospects.
- 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.

- Furthermore, titanium dioxide has been shown to possess antioxidant properties
By September, demand in the construction sector had significantly increased; however, resurgent cases of virus hindered the anticipated recovery in demand. However, due to a severe fall in market fundamentals in some end-use areas, its prices had significantly faded by quarter-end. Delays in a number of commercial projects, followed by a poor recovery in the downstream automotive market, were identified as primary causes of the protracted recovery curve.
- Finally, gravimetric analysis is a traditional method for determining barium in TiO2. This technique involves weighing the precipitate formed by reacting the sample with a reagent and then calculating the mass of barium present. Gravimetric analysis offers high accuracy and precision, but it is time-consuming and labor-intensive.
- Titanium dioxide, commonly known as TiO2, is a naturally occurring oxide of titanium. Among its two primary crystal forms, rutile TiO2 is particularly valued for its high refractive index and exceptional hiding power, making it an essential component in the production of emulsion latex paints. The unique properties of rutile titanium dioxide enhance the quality and performance of latex paints, establishing its manufacturer's reputation for producing top-tier products.

- The price of wholesale superfine calcium carbonate can vary depending on factors such as the grade of the product, the quantity purchased, and the supplier. It is important to compare prices from different suppliers to ensure that you are getting the best deal possible. Some suppliers may offer discounts for larger quantities, so it can be beneficial to purchase in bulk if you have a high demand for the product.
It's also used in sunscreens as a UV filtering ingredient, helping to protect a person's skin by blocking absorption the ultraviolet light that can cause sunburn and cancer.
The National Cancer Institute tested TiO2 for possible carcinogenicity by the oral route of exposure by feeding rats and mice with TiO2 (size not specified) at doses 25,000 or 50,000 ppm TiO2 for 103 weeks. They concluded that TiO2 was not carcinogenic.Also, the study with rats fed diets containing up to 5 % TiO2 coated mica for 130 weeks showed no treatment-related carcinogenicity. Since the size and other TiO2 properties were not specified or determined, we cannot generalize this conclusion and we have to take into account other possible outcomes of this scenario in different exposure conditions (other size/crystalline structure of TiO2 etc.).
In a review published in 2022 in the journal Archives of Toxicology, researchers found that the ingestion of E171 is a “a definite health risk for consumers and their progeny.” After reviewing dozens of in vivo, ex vivo and in vitro studies on the toxicity of E171, the researchers wrote that two facts must be noted: “First, reprotoxicity studies show that animals of both sexes are impacted by the toxicity of these nanoparticles, underlining the importance of conducting in vivo studies using both male and female animals. Second, human exposure begins in utero via maternal-fetal transfer and continues after birth by breastfeeding. Children are then chronically re-exposed due to their food preferences. To be relevant to the human in vivo situation, experimental studies should therefore consider nanoparticle exposure with respect to the age or life period of the studied population.”

It is opaque and glossy, and provides bright whiteness with blue undertones.

The committee could not finalize the assessment of some other flavoring agents, requiring further information. JECFA highlighted the importance of receiving complete data submissions from the sponsors for conducting the safety evaluation.

In a study published in the journal Toxicology, researchers examined the effects of exposing human colon cancer cell line (HTC116) titanium dioxide food additives in vitro. “In the absence of cytotoxicity, E171 was accumulated in the cells after 24 hours of exposure, increasing granularity and reactive oxygen species, inducing alterations in the molecular pattern of nucleic acids and lipids, and causing nuclei enlargement, DNA damage and tubulin depolymerization,” the scientists wrote. Researchers removed the additive from the culture, then examined the results 48 hours later. They found, “The removal of E171 was unable to revert the alterations found after 24 h of exposure in colon cells. In conclusion, exposure to E171 causes alterations that cannot be reverted after 48 h if E171 is removed from colon cells.”

In recent decades, concerns for the risks of titanium dioxide consumption have grown.
Lithopone was developed in the 1870s as a substitute for lead carbonate (lead white), to overcome its drawbacks of toxicity and poor weathering resistance. Within a few years, titanium dioxide displaced lithopone to become the white pigment (PW6) par excellence in the industry and the world’s best-selling inorganic pigment. However, titanium is a product whose price is subject to large price variations due to product availability. These price increases affect the competitiveness of finished products, and so the search for an alternative to titanium dioxide has generated a variety of possibilities to optimise its use.
