The properties of lithopone are very suitable for use in the production of coatings. Because the ingredients of lithopone are zinc sulfide and barium sulfate, and the more zinc sulfide content, the stronger its covering power. This indicates a paint product with strong white covering power. It is different from water in that it reacts with acid but does not react with alkali. It has a wide range of uses. Because its structural properties are similar to titanium dioxide and its price is relatively cheap, it can also be used as a substitute for some titanium dioxide. Lithopone can be used for coloring paints, inks, pigments, rubber, paper, leather, enamel, etc.
When choosing lithopone, you must choose a good brand and pay attention to its production date. Some people just don’t pay attention to this aspect and often pursue cheap prices. As a result, they buy products that are close to their expiration date and have not been stored for long. It is no longer usable. This is very important.
TiO2 comes in many different forms. However, only a few of these forms are considered food-grade (acceptable to be added to food). Many studies that raised concern about the safety of TiO2, including the concern for genotoxicity, used forms of TiO2 that are not considered acceptable for use in food and have different properties than food-grade TiO2. Other studies did use food-grade TiO2, but took steps to break the material down into smaller particles than what would normally be found in food.
Procurement strategies have also evolved with the rise of digital platforms. E-procurement systems streamline the buying process, allowing real-time monitoring of inventory, automating purchase orders, and enhancing supply chain transparency. Moreover, blockchain technology is being explored to ensure traceability and ethical sourcing of TIO2, addressing concerns about responsible mining practices.The US and Canada, however, approve the use of titanium dioxide as a food additive. Canada's recent review of titanium dioxide reconfirmed its safety and pointed out that many of the toxicity studies the EU reviewed were not relevant to the safety of titanium dioxide as a food ingredient, and that the ban is based on an abundance of caution and uncertainty.
The FDA categorized titanium dioxide as “Generally Recognized as Safe,” but there are warnings about its potential dangers from other organizations.
CSPI’s Chemical Cuisine is the web’s definitive rating of the chemicals used to preserve foods and affect their taste, texture, or appearance. Besides titanium dioxide, the group recommends avoiding artificial sweeteners like aspartame, acesulfame potassium, and sucralose, as well as synthetic food dyes like Yellow 5 and Red 3. CSPI and others have recently asked the Food and Drug Administration to ban the latter dye in foods and ingested drugs because the FDA has already determined that it is a carcinogen unsafe for use in cosmetics.
Preparation of Lithopone:
One of the key benefits of using anatase titanium dioxide in paints is its high opacity and hiding power. This pigment is able to cover imperfections on the substrate and create a smooth and even finish. Additionally, anatase titanium dioxide is resistant to weathering, UV radiation, and chemicals, which ensures the durability and longevity of the paint film. After the mixing, the concrete is poured into molds or forms, where it undergoes a curing processLithopone B301 is a synthetic pigment composed of a blend of zinc sulfide and barium sulfate. This unique combination offers several advantages over other pigments, such as high opacity, excellent hiding power, and good stability under various conditions. These qualities make it particularly useful in producing high-quality paints, plastics, and other products where consistent color and durability are paramount.
