One of the most exciting aspects of PQQ is its neuroprotective properties. Research indicates that PQQ may stimulate the production of nerve growth factor (NGF), essential for the survival and maintenance of neurons. This attribute suggests its potential as a cognitive enhancer, offering promise in combating age-related cognitive decline and neurodegenerative diseases like Alzheimer's. By fostering the growth of new mitochondria and promoting nerve growth, PQQ not only energizes the brain but also supports long-term brain health.

Titanium dioxide is a versatile material with a wide range of applications. Some of its most common uses include:
1. Pigment and Food Coloring
Titanium dioxide is one of the most widely used white pigments, often used to add whiteness and brightness to products. It is used in the production of paints, coatings, plastics and other products to provide a white color or opacity.
It’s also used in food products to provide a white color. Candies, cakes and creamers are examples of foods that may contain titanium dioxide for its color enhancing and bleaching properties.
2. Cosmetics
Titanium dioxide is often used as a UV absorber and pigment in cosmetic products, such as foundations, lipsticks, creams, sunscreens and other skin care products. It helps protect the skin from the harmful effects of UV rays by blocking them, while providing a brightening effect.
However, it can cause photosensitivity, which - In conjunction with Ponceau 4R, the factory also produces Titanium Dioxide, a versatile pigment known for its brilliant white hue and exceptional opacifying properties. It is widely used in paints, plastics, paper, and textiles. The manufacture of Titanium Dioxide here involves advanced chemistry techniques that transform raw ore into a fine, consistent pigment suitable for myriad industrial uses.

Uses & Benefits
Moreover, a 2019 study noted that food-grade titanium dioxide was larger and not nanoparticles. Hence, the authors concluded that any titanium dioxide in food is absorbed poorly, posing no risk to human health (3Trusted Source).
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.

Overall, r 996 titanium dioxide suppliers have established themselves as reliable and reputable sources for this essential pigment. With their high-quality products, reliable supply chain, competitive pricing, and excellent customer service, businesses can rely on these suppliers for all their r 996 titanium dioxide needs. Partnering with r 996 titanium dioxide suppliers is a smart choice for businesses looking to enhance their production processes and deliver top-quality products to their customers.
Lithopone’s historical significance is further accentuated by the advancements and modifications that followed its inception. The 1874 patent by J.B. Orr, for instance, ushered in a new white pigment—Orr’s Zinc White. This innovation was attained by co-precipitating zinc sulfate and barium sulfide, followed by a calcination process. Further refinements marked the subsequent decades, the most notable being the enhancement of lightfastness achieved in the 1920s by introducing small amounts of cobalt salts before calcination.
