  • In a study published in 2022 in the journal Particle and Fibre Technologyresearchers examined the impact of maternal exposure to titanium dioxide nanoparticles in newborn offspring mice. They found that “a chronic exposure to TiO2 NPs during pregnancy alters the respiratory activity of offspring, characterized by an abnormally elevated rate of breathing.” Breathing was also shown to be “significantly and abnormally accelerated,” and the ability for neural circuitry to effectively adjust breathing rates was impaired. The researchers concluded: “Our findings thus demonstrate that a maternal exposure to TiO2 NPs during pregnancy affects the normal development and operation of the respiratory centers in progeny.”

  • Titanium Dioxide (TiO2) is a widely used white pigment in the manufacturing of paints, plastics, and coatings due to its excellent whiteness, opacity, and chemical stability. It is also used in sunscreens, food packaging, and other applications where its whitening effect is desired.
  • On the other hand, lithopone is relatively inexpensive and easy to produce. It is also considered to be safer than TiO2, as it does not pose the same health risks. However, its hiding power and whiteness are not as good as those of TiO2.


  • Pure PVB is non-toxic and harmless to human body. In addition, ethyl acetate or alcohol can be used as solvent, so PVB is widely used in printing ink of food containers and plastic packaging in European and American countries.

    Storage safety properties

    PVB can be stored for two years without affecting its quality as long as it is not in direct contact with water; PVB shall be stored in a dry and cool place and avoid direct sunlight. Heavy pressure shall be avoided during PVB storage.

    Solubility

    PVB is soluble in alcohol, ketone, ester and other solvents. The solubility of various solvents changes according to the functional group composition of PVB itself. Generally speaking, alcohol solvents are soluble, but methanol is more insoluble for those with high acetal groups; The higher the acetal group, the easier it is to dissolve in ketone solvents and ester solvents;

    PVB is easily soluble in cellosolve solvents; PVB is only partially dissolved in aromatic solvents such as xylene and toluene; PVB is insoluble in hydrocarbon solvents.

    Viscosity characteristics of PVB solution

    The viscosity of PVB solution is greatly affected by the formula of solvent and the type of solvent; Generally speaking, if alcohol is used as solvent, the higher the molecular weight of alcohol, the higher the viscosity of PVB solution;

    Aromatic solvents such as xylene and toluene and hydrocarbon solvents can be used as diluents to reduce the viscosity of PVB solution; The effect of PVB chemical composition on viscosity is summarized as follows: under the same solvent and the same content of each base, the higher the degree of polymerization, the higher the solution viscosity; Under the same solvent and the same degree of polymerization, the higher the acetal group or acetate group, the lower the solution viscosity.

    Dissolution method of PVB

    Where mixed solvents are used, the dissolution step is to first put aromatic solvents (such as xylene, toluene, etc.) or ester solvents (such as n-butyl acetate, ethyl acetate, etc.) into the mixing, slowly put PVB into the mixing, and then add alcohol solvents (such as n-butanol, ethanol, etc.) after PVB is dispersed and expanded,

    At this time, the dissolution time can be shortened by heating; Using this dissolution method, the formation of lumpy PVB can be avoided (because the dissolution time will be several times after the formation of lumpy PVB), so the dissolution speed can be accelerated. Generally, the ratio of aromatic and alcohol solvents is 60 / 40 ~ 40 / 60 (weight ratio), and PVB solution with low viscosity can be prepared.

    The solvent composition contains 2 ~ 3wt% water, which can improve the hydrogen bonding strength of alcohol solvents and help the solubility of PVB.

    Processing properties

    Although PVB resin is a thermoplastic, it has little processability before plasticizer is added. Once plasticizer is added, its processability is very easy.

    The purpose of general coatings and adhesives is to change the resin characteristics by adding plasticizers to meet the application requirements, such as film softness, reducing the TG point of the resin, reducing the heat sealing temperature, maintaining low-temperature softness, etc.

    Compatibility

    PVB can be compatible with a variety of resins, such as phenolic resin, epoxy resin, alkyd resin and 
    MELAMINE resin.

    B-08sy, b-06sy and b-05sy with high acetal degree can be mixed with nitrocellulose in any proportion. PVB and alkyd resin are partially compatible. General PVB is compatible with low molecular weight epoxy resin, while high molecular weight epoxy resin needs PVB with high acetal degree to be compatible with each other.

  • Coronavirus-related shutdowns in the first half of the quarter prompted forcible measures at several small-scale ilmenite factories in China and India, subsequently exacerbating the Titanium supply problem. The chemical's tight supply condition was extended until the end of the quarter, as few participants were heard holding cargoes in expectation of an exceptional surge in its seasonal demand.

  • In 2019, EFSA published a statement on the review of the risk related to the exposure to food additive titanium dioxide (E171) performed by the French Agency for Food, Environment and Occupational Health Safety (ANSES). In its statement, EFSA highlighted that the ANSES opinion reiterated the uncertainties and data gaps previously identified by EFSA and did not present findings that invalidated the Authority’s previous conclusions on the safety of titanium dioxide.

  • Safety is another critical aspect when considering the use of any additive in food products. Food-grade titanium dioxide is generally recognized as safe (GRAS) by the U.S. Food and Drug Administration (FDA) when used in accordance with good manufacturing practices. However, it is essential for manufacturers to adhere strictly to recommended usage levels to ensure consumer safety.
  • However, it is important to note that barium sulfate should be used judiciously and only after considering potential risks and benefits for each individual patient. Allergic reactions to barium are rare but can be severe, necessitating careful evaluation before administration. Moreover, since barium can obscure details on subsequent CT scans, it is imperative to coordinate the timing of these tests appropriately.

  • Some websites maintain titanium dioxide is inferior to zinc oxide, another mineral sunscreen ingredient whose core characteristics are similar to those of titanium dioxide. The reality is that titanium dioxide is a great broad-spectrum SPF ingredient and is widely used in all manner of sun-protection products. What gets confusing for some consumers is trying to decipher research that ranks sunscreen ingredients by a UV spectrum graph. By most standards, broad-spectrum coverage for sunscreen ingredients is defined as one that surpasses 360 nanometers (abbreviated as “nm” - how the sun’s rays are measured). Titanium dioxide exceeds this range of protection, but depending on whose research you read, it either performs as well as or slightly below zinc oxide.

  • Our titanium dioxide products are known for their exceptional whiteness, brightness, and opacity, making them ideal for a wide range of applications. Whether you need titanium dioxide for use in sunscreen, paint, or food coloring, we have the right product for you.
