  • In terms of refractive index and opacity, lithopone surpasses zinc oxide and lead oxide. Lithopone's high refractive index allows it to efficiently scatter and reflect light, thereby increasing the opacity of various media. Whether you need to enhance the opacity of paints, inks or plastics, lithopones deliver outstanding results, ensuring your final product is completely opaque.

  • For that reason, the Center for Science in the Public Interest has graded titanium dioxide as a food additive that consumers should seek to “avoid.” Scientists at the nonprofit nutrition and food safety watchdog group today published a new entry for titanium dioxide in its Chemical Cuisine database of food additives.  

  • The FDA has not updated its general guidance on safety assessments since 2007. Within that time, there has been a significant increase in research on the confluence of toxicology, nanotechnology and human health. The EU updates its guidance regularly with new science available to offer proper safety assessments, with its most recent update published in 2021.

  • Having thus described the origin and uses of the pigment, we now come to the question, what is lithopone? It is, in short, a chemical compound usually consisting of 30.5 per cent zinc sulphide, 1.5 per cent zinc oxide and 68 per cent barium sulphate, but these proportions vary slightly in the different makes. Lithopone of this composition is sold as the highest grade, either as red seal or green seal, as it best suits the idea of the manufacturer. Many manufacturers, especially in Europe, sell and also export other brands under other seals, containing 24, 20, 18 and as little as 12 per cent of zinc sulphide with very small percentages of zinc oxide, the balance being usually barium sulphate, but sometimes certain portions of China clay or gypsum (calcium sulphate) or whiting (calcium carbonate). Such brands are not a chemical compound, but mechanical mixtures of the chemically compounded lithopone and the admixtures referred to.

  • Firstly, Lithopone B311 powder's primary function lies in its use as a white pigment. It imparts a brilliant white color to products, making it a popular choice in the paint and coatings sector. Its high opacity and ensure effective coverage, reducing the need for excessive layers, thus contributing to cost-effectiveness. Additionally, its stability under heat and light exposure makes it suitable for outdoor applications where durability is paramount.
  • The commitment to excellence does not stop at production methods; it extends to the research and development of new lithopone formulations
  • Mexican researchers sought to evaluate the effects of E171 across a span of conditions in mice, including its influence on behavior, along with the effects on the colon and liver. The research, published in 2020 in the journal Food and Chemical Toxicology, showed that E171 promoted anxiety and induced adenomas, or noncancerous tumors, in the colon. They also found that E171 heightened goblet cells hypertrophy and hyperplasia, which is typically seen in asthma patients and triggered by smoking or external pollutants and toxins. They also noted mucins overexpression in the mice, which can be linked to cancer cell formation. 

  • China's TiO2 market has been growing rapidly in recent years, fueled by the country's booming manufacturing sector and increasing demand for high-quality pigments. With a large number of manufacturers and abundant resources, China has emerged as a key player in the global TiO2 market.
