A few non-dietary studies have reported adverse effects in the gastrointestinal tract of laboratory animals given food-grade TiO2. However, these same effects were not seen when the same or higher doses of food-grade TiO2 were administered in the animals' diet. Dietary studies best reflect how humans are exposed to TiO2 from food. Thus, the Food Directorate placed the most emphasis on the results of these studies in the state of the science report.
In conclusion, titanium dioxide stands as a testament to the marvels of chemistry and engineering. As we continue to explore its potential, it remains an essential part of the wholesale pigment industry, contributing to products that touch every aspect of our lives. From enhancing the vibrancy of colors to combating pollution and advancing renewable energy technologies, titanium dioxide is indeed a remarkable substance with an ever-expanding palette of applications.Lithopone B301, Lithopone B311 powder’s 2 main components:
A legal additive in the United States, titanium dioxide is used in everything from food to consumer goods and the U.S. Food and Drug Administration says regulated use of the product as a color additive in food is safe within certain restrictions.
In interior applications, titanium dioxide's non-toxic nature makes it suitable for use in areas with high human contact, such as homes and officesTitanium dioxide is a naturally-occurring mineral found in the earth’s crust. Because of its white color, opaqueness, and ability to refract light, the ingredient is often used as a pigment, brightener, and opacifier, which is an ingredient that makes a formulation more opaque. Titanium dioxide is also a UV filter and so is an effective active ingredient in sunscreens. It’s often used in cosmetic loose and pressed powders, especially “mineral powder” cosmetics, in addition to other cosmetics, lotions, toothpaste, and soap.
Lithopone is a white pigment composed of a mixture of barium sulfate (BaSO4) and zinc sulfide (ZnS). It is commonly used in the production of paints, plastics, rubber, and various other industrial applications. As such, manufacturers and distributors often provide Material Safety Data Sheets (MSDS) to ensure the safe handling and use of the product.
However, since it’s photosensitive — meaning it can stimulate free radical production — it’s usually coated in silica or alumina to prevent potential cell damage without reducing its UV-protective properties (7Trusted Source).
In conclusion, understanding the nuances of lithopone pricing and selecting reputable manufacturers are key steps in ensuring that businesses acquire the right product for their specific requirements. By engaging with manufacturers known for their quality, innovation, and sustainability efforts, consumers can make informed decisions that align with both their operational needs and broader environmental goals. Production ProcessFreshwater 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.
Titanium dioxide (TiO2) is a chemically inert inorganic compound and an insoluble white solid that occurs naturally in several minerals, including rutile, anatase, and brookite. It is created synthetically from the mineral ilmenite. It is an insoluble white solid. Anatase, when compared to brookite and routine, has the most industrial applications, but it is the most toxic form of TiO2.
lithopone supplier 30% complies with both the REACH and Indirect Food Regulations, as well as with many European regulations regarding Toys, Packaging, Resins, etc…

JECFA also evaluated estimates of dietary exposure to titanium dioxide, estimating the maximum 95th percentile of exposure to be 10 mg/kg BW per day. Overall, considering the low oral absorption of titanium dioxide as a food additive, the committee reaffirmed the ADI “not specified” that was established at the 13th meeting.
Prof. Maged Younes, Chair of EFSA’s expert Panel on Food Additives and Flavourings (FAF), wrote of the decision: “Taking into account all available scientific studies and data, the Panel concluded that titanium dioxide can no longer be considered safe as a food additive. A critical element in reaching this conclusion is that we could not exclude genotoxicity concerns after consumption of titanium dioxide particles. After oral ingestion, the absorption of titanium dioxide particles is low, however they can accumulate in the body.”
