4. Safety Ponceau 4R and titanium dioxide are approved for use in cosmetics by regulatory agencies around the world, and they have been extensively tested for safety.

Wegman’s puts titanium dioxide in its Original Macaroni and Cheese. Campbell’s Healthy Request Chunky Chicken Corn Chowder has it, as does Food Club’s Chunky New England Clam Chowder. Marzetti uses the color agent to brighten its Cream Cheese Fruit Dip. Dairy products usually don’t need titanium dioxide to look white, but Kroger has decided to add titanium dioxide to its Fat Free Half-and-Half. And titanium dioxide isn’t only in especially white or brightly colored foods: Little Debbie adds it to Fudge Rounds and many other products. According to the Food Scores database maintained by Environmental Working Group, more than 1,800 brand-name food products have titanium dioxide on their ingredients list. That said, it can still lurk as an unspecified “artificial color,” or labels might simply say “color added.”

Pharmaceutical grade calcium carbonate is the highest quality grade and is used in the pharmaceutical industry for various applications such as antacids and dietary supplements. It is produced using high-quality raw materials and undergoes stringent quality control measures to ensure purity and consistency.

Lithopone Market Outlook - 2020–2027

As0 ₄ ³ — + Fe ³ — → FeAs0 ₄ \
One of the key advantages of R1930 is its high refractive index, which allows it to scatter light more effectively, resulting in superior opacity and whiteness. This makes it an ideal choice for ink formulations that require high levels of coverage and brightness. Additionally, R1930's excellent heat stability ensures that it can withstand the high temperatures encountered during the printing process without losing its color or physical properties.
In addition to its product quality, RC 823 is also known for its excellent customer service and technical support
For research published in 2022 study in the journal Food and Chemical Toxicology, scientists examined “the genotoxicity and the intracellular reactive oxygen species induction by physiologically relevant concentrations of three different TiO2 nanomaterials in Caco-2 and HT29-MTX-E12 intestinal cells, while considering the potential influence of the digestion process in the NMs’ physiochemical characteristics.” They found a “DNA-damaging effect dependent on the nanomaterial,” along with the micronucleus assay suggesting “effects on chromosomal integrity, an indicator of cancer risk, in the HT29-MTX-E12 cells, for all the tested TiO2 nanomaterials.” Researchers concluded that the results showcase “evidence of concern” regarding titanium dioxide used as a food additive.
This white pigment composed of barium sulfate and zinc sulfide, is influenced by several market drivers and trends. One significant driver is the expanding demand for lithopone in the paint and coating industry, owing to its excellent hiding power and (ultraviolet) UV resistance. The construction sector also propels the market growth of this compound, as it is widely used in architectural coatings for its durability and weather resistance. Additionally, the rising popularity of lithopone in the plastic and rubber industries, driven by its ability to enhance product opacity and stability, contributes to market expansion. Trends in this compound market include a growing emphasis on eco-friendly alternatives, stimulating research and development of sustainable production processes. Furthermore, the increasing focus on product quality and performance, along with advancements in nanotechnology applications, presents new opportunities for lithopone market players. Overall, the evolving landscape of industries utilizing this compound underscores its dynamic market, driven by both traditional applications and emerging trends.
Titanium dioxide is produced in two main forms. The primary form, comprising over 98 percent of total production, is pigment grade titanium dioxide. The pigmentary form makes use of titanium dioxide’s excellent light-scattering properties in applications that require white opacity and brightness.
The production process of lithopone involves a sophisticated synthesis of zinc sulfide and barium sulfate, resulting in a pigment that boasts high whiteness, opacity, and heat stability. The ratio of ZnS to BaSO4 can be adjusted to cater to specific applications, with some formulations containing up to 70% zinc sulfide and 30% barium sulfate. This flexibility makes lithopone an adaptable solution for manufacturers seeking optimal performance in their products.

Utility Requirements and Costs
Animal studies show exposure to titanium dioxide is linked to immunotoxicity, inflammation and neurotoxicity.
The European Commission banned titanium dioxide as a food additive in the EU in 2022 after the European Food Safety Authority (EFSA) conducted an updated safety assessment of E171 and concluded the panel could not eliminate concerns about its genotoxicity.
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.

Titanium Dioxide Description

Titanium dioxide, known for its exceptional refractive index and UV-blocking properties, is a key ingredient in various industries. The Microbar factory, however, goes beyond conventional production methods, focusing on micro-scale production that enhances efficiency and precision. The 'microbar' in its name refers to its ability to produce titanium dioxide particles at an incredibly minute scale, enabling unique performance characteristics in end-products.
