Lithopone(CAS NO.1345-05-7) is manufactured by a process in which barium sulfide solution is prepared by reducing barite ore (BaSO4) with carbon and leaching the resulting mass.

A review published in 2022 in the journal NanoImpact evaluated the latest research related to genotoxic effects of titanium dioxide through in vivo studies and in vitro cell tests. Researchers summarized the results by stating TiO2 nanoparticles “could induce genotoxicity prior to cytotoxicity,” and “are likely to be genotoxic to humans.”

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).

Overnight news titanium dioxide industry

This regulation entered into force on 7 February 2022. However, the Regulation included a six-month transitional period to allow food businesses time to phase out the use of this food additive and to reformulate their products using suitable alternatives. This period will end on 7 August 2022.

With its storied history and distinct properties, lithopone remains a subject of historical significance and contemporary relevance. While its applications and popularity have evolved, its role in the annals of pigment history is indisputable.

The R996 grade titanium dioxide from Lomon is particularly well-suited for use in the paint industry due to its superior tinting strength and dispersibility. These properties allow paint manufacturers to achieve vibrant and consistent colors in their products, resulting in high-quality finishes for a variety of applications.

Lithopone: an alternative to titanium dioxide

Above 20%, it is recommended to replace 1 kg TiO2 with 1.3 kg of lithopone supplier 30%.  

All food businesses currently using titanium dioxide as a food additive have a legal responsibility to comply with the requirements of Regulation (EU) 2022/63, banning the use of titanium dioxide. The FSAI encourages food businesses to source suitable alternatives to titanium dioxide and start the process of reformulation now to ensure compliance in advance of the ban coming into force on 7 August 2022.

Lithopone, a white pigment composed of a mixture of zinc sulfide and barium sulfate, has become an indispensable ingredient in the paint industry. Its unique properties, including excellent opacity, high brightness, and resistance to weathering, make it highly valued among paint manufacturers. As the demand for sustainable and efficient paint products grows, the role of lithopone and its suppliers has become more critical than ever.

Hiding power

How we’re exposed to an ingredient matters greatly in terms of our long-term health. 
  
Research shows that inhaling titanium dioxide particles in significant quantities over time can cause adverse health outcomes. Unless you work in an industrial setting, inhaling substantial amounts of titanium dioxide is highly unlikely. 

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 integrity of surface skin cells was evaluated with and without solar simulated irradiation. The integrity of the stratum corneum was significantly lower in individuals treated with P25TiO₂NPs under the light in comparison to the ones that received the functionalized nanoparticles. Cell membrane suffering is evident (Fig. 9), and it is in accordance with the ROS levels and macromolecule oxidation found in vitro for the irradiated P25TiO₂NPs. Disruption of the superficial skin layer was observed in all animals treated with no functionalized nanoparticles, under irradiation. This data expands the findings by the group of Professors Fubini and Fenoglio, who showed that P25TiO₂NPs could impact the lipid structure at the top few microns of the stratum corneum [55]. Control skin under irradiation and without any topic formulation did not show changes in cell structure.
