- In addition to its opacity, lithopone is also valued for its durability and resistance to light, heat, and chemicals. This makes it a reliable option for inks that need to withstand harsh conditions or long periods of exposure. Whether used for packaging materials, signage, or other printed products, lithopone ensures that the colors remain bright and the image stays clear over time.
Lithopone(CAS NO.1345-05-7) is manufactured by a process in which barium sulfide solution is prepared by reducing barite ore (BaSO4) with carbon and leaching the resulting mass.
- Manufacturers and suppliers specializing in titanium dioxide coatings play a crucial role in delivering these benefits to end-users. They ensure that the titanium dioxide is of high purity, uniformly dispersed, and properly formulated to meet specific application needs. The expertise of these suppliers is paramount in developing coatings that not only protect substrates but also enhance their aesthetic appeal.
In general, nanoparticles have been shown to accumulate in the body, particularly in organs in the gastrointestinal tract, along with the liver, spleen, and capillaries of the lungs.

Although barium sulfate is almost completely inert, zinc sulfide degrades upon exposure to UV light, leading to darkening of the pigment. The severity of this UV reaction is dependent on a combination of two factors; how much zinc sulfide makes up the pigments formulation, and its total accumulated UV exposure. Depending on these factors the pigment itself can vary in shade over time, ranging from pure white all the way to grey or even black. To suppress this effect, a dopant may be used, such as a small amount of cobalt salts, which would be added to the formulation. This process creates cobalt-doped zinc sulfide. The cobalt salts help to stabilize zinc sulfide so it will not have as severe a reaction to UV exposure.

There are two primary forms of titanium dioxide commercially available: anatase and rutile. The rutile form is typically used in sunscreens due to its superior ability to handle UV rays and stability in the presence of UV light. The anatase form is typically used in other types of products, such as paint. Another plus of the rutile form is that its UVA protection extends past 400 nanometers, which is the upper limit of UVA.

The mineral appears to have low skin penetration, but it is a greater concern when inhaled frequently over time.

Freshwater algae show low-to-moderate susceptibility to TiO2 exposure, with more pronounced toxic effects in the presence of UV irradiation. It has also been shown that nano-sized TiO2 is significantly more toxic to algae Pseudokirchneriella sub-capitata than submicron-sized TiO2. Hund-Rinke and Simon reported that UV irradiated 25 nm TiO2 NPs are more toxic to green freshwater algae Desmodesmus subspicatus than UV irradiated 50 nm particles, which is in agreement with Hartmann et al. UV irradiated TiO2 NPs also inactivated other algae species such as Anabaena, Microcystis, Melsoira and Chroococcus. It was demonstrated that smaller particles have a greater potential to penetrate the cell interior than submicron-sized particles and larger aggregates. Studies have shown that the amount of TiO2 adsorbed on algal cells can be up to 2.3 times their own weight.
