In recent years, there has been a growing focus on sustainability and environmental responsibility in the manufacturing industry. Titanium dioxide manufacturers are no exception, with many companies implementing eco-friendly practices to minimize their impact on the environment. This includes reducing energy consumption, implementing recycling programs, and exploring alternative production methods that are more environmentally friendly.
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.”

But in 2021, EFSA reevaluated titanium dioxide to consider the impacts of its nanoparticle. After considering more studies, EFSA concluded that nanoparticle-size titanium dioxide can accumulate in the body, break DNA strands and cause chromosomal damage.
In their role as risk managers, the European Commission and Member States will now reflect on EFSA’s scientific advice and decide upon any appropriate regulatory measures or advice for consumers.
It adds a bright white color to coffee creamers, baked goods, chewing gums, hard-shell candies, puddings, frostings, dressings, and sauces. But the nanoparticles found in “food-grade” titanium dioxide may accumulate in the body and cause DNA damage—which is one way chemicals cause cancer and other health problems.
It's sort of ironic, maybe ironic is the wrong word, that the ingredient in paint that makes your kitchen shiny also makes your Hostess cupcakes shiny, Environmental Working Group's senior vice president of government affairs Scott Faber added.
Calcium carbonate and titanium dioxide are two important minerals that are widely used in various industries. While they share some similarities, they also have distinct differences when it comes to their manufacturing processes and applications.
It offers several advantages in various applications. Its excellent opacity and brightness make it a popular choice in the production of paints, coatings, and printing inks, providing a cost-effective alternative to titanium dioxide. Lithopone's chemical stability enhances its durability in outdoor environments, making it suitable for outdoor coatings. Additionally, its low reactivity and compatibility with other pigments contribute to its versatility. Beyond coatings, lithopone finds utility in plastics, rubber, and paper industries. Overall, its multifaceted advantages and broad applications underscore this compound's significance in diverse industrial sectors.

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.

Polyvinyl Butyral Resin (PVB) is a solvent Resin synthesized by the acetal reaction of Polyvinyl Alcohol (PVA) and butyraldehyde in contact with coal.
Because Pvb Resin itself contains a lot of hydroxyl groups, it can bridge with some thermosetting resins to improve the properties of chemicals and film hardness.
Because PVB resin has the above excellent characteristics, it is widely used in adhesive safety glass intermediate film of automobile and building, rust cutting primer, baking paint, wood paint, printing ink, adhesive of electronic ceramics and printed circuit board, adhesive between metal and metal, between metal and plastic, modifier of hot-melt adhesive, iron dimension waterproof processing of textile, etc. A variety of new industrial applications are also continuously developed and applied.
The general characteristics of PVB are as follows:
The appearance of polyvinyl butyral (PVB) resin is white spherical porous particles or powder, and its specific gravity is 1:1; However, the filling density is only 0.20 ~ 0.35g/ml.
Thermal properties
The glass transfer temperature (TG) of polyvinyl butyral (PVB) resin ranges from 50 ℃ of low degree of recombination to 90 ℃ of high degree of recombination; The glass transfer temperature can also be adjusted by adding an appropriate amount of Plasticizer to reduce it below 10 ℃.
Mechanical properties
The coating of polyvinyl butyral (PVB) resin has good water resistance, water resistance and oil resistance (it is resistant to aliphatic, mineral, animal and vegetable oils, but not to sesame oil). PVB is widely used in printing inks and coatings because it contains high hydroxyl groups and has good dispersibility to pigments.
In addition, its chemical structure contains both hydrophobic acetal and acetic ACID groups and hydrophilic hydroxyl groups, so PVB has good adhesion to glass, metal, plastic, leather and wood.
Chemical reaction
Any chemical that can react with secondary alcohol will also react with PVB. Therefore, in many applications of PVB, it is often used with thermosetting resin to bridge and harden with the hydroxyl group of PVB, so as to achieve the characteristics of chemical resistance, solvent resistance and water resistance.
Of course, films with different characteristics (such as hardness, toughness, impact resistance, etc.) can be prepared according to different types of thermosetting resin and different mixing ratio with PVB.
Safety properties
Conclusion
It adds a bright white color to coffee creamers, baked goods, chewing gums, hard-shell candies, puddings, frostings, dressings, and sauces. But the nanoparticles found in “food-grade” titanium dioxide may accumulate in the body and cause DNA damage—which is one way chemicals cause cancer and other health problems.
