In a 2021, Chinese researchers examined the impact of E171 on lipid digestion and vitamin D3 bioaccessibility in a simulated human gastrointestinal tract model. They examined Vitamin D’s bioaccessibility, or the amount it was released in the gastrointestinal tract, becoming available for absorption, and found it “significantly decreased from 80% to 74%” with the addition of E171. In the experiment, E171 decreased lipid digestion dose-dependently. Researchers wrote: “The findings of this study enhance our understanding toward the potential impact of E171 on the nutritional attributes of foods for human digestion health.” The study was published in the Journal of Agricultural and Food Chemistry,
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.

Third, the composition of zinc sulfide and barium sulfate in the product is controllable, and the type of product can be adjusted according to the market.- Both 28B301 and 30B311 are white pigments with high brightness and excellent covering power. They are commonly used in coatings, plastics, rubber, and paper industries. The main difference between these two grades lies in their particle size distribution. 28B301 has a smaller particle size, resulting in higher opacity and better dispersion. On the other hand, 30B311 has a larger particle size, which makes it more suitable for applications that require good rheological properties.
- Factories that produce lithopone pigment follow strict quality control measures to ensure that the compound meets industry standards for purity and consistency. Advanced manufacturing processes are used to create a finely ground powder that is easy to disperse and blend into various products. This attention to detail helps to guarantee the performance and longevity of products that contain lithopone pigment.
- Moreover, TiO2 can also improve the mechanical properties of plastics. It increases the stiffness and strength of the material, making it more resistant to impact and deformation. This is particularly beneficial in applications where plastics are subjected to stress or pressure, such as automotive parts and construction materials. By incorporating TiO2 into their formulations, manufacturers can create stronger and more durable plastic products without sacrificing their lightweight nature.
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.
Additives (Biocide, pH Corr., Antifoam, etc.) Titanium dioxide (TiO2). Titanium dioxide is the most common white pigment used today. As a pigment, titanium dioxide is unique because it combines both high colouring and high opacifying capacity. This is mainly due to its high refractive index (2.7). Furthermore, titanium dioxide is an excellent UV absorber (it is used in sun protective creams). Some typical properties are: density 3.3-4.25 g/cm3; pH of water suspension 3.5-10.5; particle size 8–300 nm; oil absorption 10–45 g/100 g; specific surface area 7–160 m2/g. Most titanium dioxide is produced from the rutile (TiO2) or ilmenite (titanate of ferrous iron). Titanium dioxide can be obtained using different processes.
What is an exposure route?
- The production process of titanium dioxide powder mainly includes ore selection, acid decomposition, hydrolysis, washing, drying, calcination, and crushing. During this process, strict quality control is required to ensure that the final product meets the relevant standards. Moreover, environmental protection measures must be taken during the production process to minimize the impact on the environment.
Titanium dioxide is added to some food packaging to preserve the shelf life of a product.
