Titanium dioxide in sunscreen
- NIOSH's primary concern with titanium dioxide lies in its use as a pigment in paints, plastics, and other industrial products, where workers may be exposed to airborne particles. TiO2 is generally considered safe when used in its solid form; however, inhalation of fine dust particles can pose respiratory risks. NIOSH conducts rigorous studies to establish recommended exposure limits (RELs) to ensure worker safety.
Lithopone in plastics and masterbatch
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.

How do I know if a Unilever product contains titanium dioxide?
In food, titanium dioxide has a few different uses. Most notably, its food-grade form is used as a colorant to enhance and brighten the color of white foods such as dairy products, candy, frosting, and the powder on donuts. For foods that are sensitive to UV light, titanium dioxide is used for food safety purposes to prevent spoilage and increase the shelf life of food.
- In conclusion, wholesale talc and titanium dioxide are essential minerals that play a crucial role in the cosmetics and pharmaceutical industries.

2.3(ZnS), 1.64(BaSO4) - Quality control is paramount in the manufacture of zinc barium sulfate
- Despite its extensive use, there are ongoing efforts to improve TiO2's performance and explore new applications. Nanotechnology has unlocked possibilities for creating nanoparticles of TiO2, enhancing its surface area and photocatalytic properties. Research is also delving into the potential of TiO2 in areas like cancer therapy, water desalination, and energy storage.
In a review published in 2022 in the journal Archives of Toxicology, researchers found that the ingestion of E171 is a “a definite health risk for consumers and their progeny.” After reviewing dozens of in vivo, ex vivo and in vitro studies on the toxicity of E171, the researchers wrote that two facts must be noted: “First, reprotoxicity studies show that animals of both sexes are impacted by the toxicity of these nanoparticles, underlining the importance of conducting in vivo studies using both male and female animals. Second, human exposure begins in utero via maternal-fetal transfer and continues after birth by breastfeeding. Children are then chronically re-exposed due to their food preferences. To be relevant to the human in vivo situation, experimental studies should therefore consider nanoparticle exposure with respect to the age or life period of the studied population.”
- Eco-friendly TiO2 suppliers are those that prioritize minimizing their ecological footprint throughout the supply chain. They achieve this by implementing rigorous environmental management systems, using renewable energy sources where possible, reducing waste, and ensuring responsible sourcing of raw materials. Some suppliers go a step further by investing in research and development to create more efficient production methods that reduce energy consumption and pollutant release.
- Moreover, wholesalers should ensure that the manufacturing process complies with Good Manufacturing Practices (GMP), ensuring the product's quality and safety. This includes regular testing for impurities and monitoring the production environment to minimize dust exposure.
- One of the primary uses of titanium dioxide is as a pigment in cosmetics and personal care products. It provides a natural, white color to products such as foundations, powders, and lipsticks, making them look more appealing to users.
