Lithopone B311 Datasheet

When manufacturers add titanium dioxide to foods and other ingestible products, it’s typically referred to as E171, which relates to food-grade purity.

Until relevant toxicological and human exposure data that would enable reliable risk assessment are obtained, TiO₂ nanoparticles should be used with great care.

In industrial settings, people can be exposed to titanium dioxide through inhalation. Inhalation exposure to titanium dioxide is exceedingly rare for most people. 

Because beauty should never come at the price of your health.

Lithopone 30% is the perfect solution for partial substitution of TiO2 in fillers due to its very soft nature and hardly any shrinkage properties. 

LITHOPONE

Calcium carbonate and titanium dioxide are two important minerals that are widely used in various industries. While they share some similarities, they also have distinct differences when it comes to their manufacturing processes and applications.

Lithopone powder is a versatile and indispensable ingredient in various industries, contributing to the quality, durability, and aesthetic appeal of numerous products. From paints and coatings to plastics and ceramics, its high opacity, UV resistance, and cost-effectiveness make it a preferred choice for manufacturers worldwide. As advancements in manufacturing and formulation techniques continue, lithopone powder is expected to remain a key player in the global pigment market, fulfilling diverse needs and driving innovation across industries.

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.

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.
