Most notably, a European Food Safety Authority safety assessment published in May 2021 pointed to genotoxicity concerns, as suggested by previous research. Genotoxicity is the ability of chemicals to damage genetic information such as DNA, which may lead to cancer.
- Physical and Chemical Properties
- Once the pigment batches have passed all quality checks, they are packaged and distributed to manufacturers of paint, coatings, inks, plastics, and countless other products. The impact of these pigment factories extends far beyond the art studio, influencing architecture, fashion, automotive, and numerous other industries that rely on color to communicate and captivate.
Application:
1. Due to its rheological and optical properties, Lithopone offers technical and economic advantages wherever organic and inorganic resin systems need to be relatively highly pigmented for specific applications. Lithopone has therefore traditionally been used in putties, mastics, jointing and sealing compounds, primers, undercoats and marking paints. In powder coatings it is possible to replace TiO2 partially, very economically.
2. The low Mohs' hardness of Lithopone leads to low abrasiveness in comparison with TiO2.
3. Lithopone 30 % (= 30% zinc sulfide share) is proven to be of particular use as a TiO2 Substitute in thermoplastic masterbatches. Even at very high pigment loadings it disperses easily. A masterbatch containing 50 % TiO2 and 25 % Lithopone 30 % DS has the same hiding power as one containing 60 %TiO2. Cost savings are strongly related to the price ratio of Lithopone and TiO2 and the price of for example polyethylene or polypropylene.
4. The Lithopone batch has a much higher extrusion rate too. Furthermore the impact strength of many thermoplastics such as PP and ABS can be noticeably improved by using Lithopone as a TiO2 substitute. Generally spoken, Lithopone can be used at loadings up to 80 % by weight without causing polymer breakdown
Magnesium can be made by several methods (Fig. 1), but the most common method of manufacture is by the electrolytic process, as for example the electrolysis of magnesium chloride.

Mexican researchers sought to evaluate the effects of E171 across a span of conditions in mice, including its influence on behavior, along with the effects on the colon and liver. The research, published in 2020 in the journal Food and Chemical Toxicology, showed that E171 promoted anxiety and induced adenomas, or noncancerous tumors, in the colon. They also found that E171 heightened goblet cells hypertrophy and hyperplasia, which is typically seen in asthma patients and triggered by smoking or external pollutants and toxins. They also noted mucins overexpression in the mice, which can be linked to cancer cell formation.

When asked about the recent Skittles lawsuit, the FDA said the agency does not comment on pending litigation.
In recent years, environmental concerns have shaped the way lithopone is produced and used. Suppliers are now more attentive to the sustainability aspect of their operations, ensuring that lithopone is sourced from eco-friendly processes. Many suppliers have adopted responsible mining practices and have invested in technologies that reduce waste and emissions during production. This shift not only appeals to environmentally-conscious consumers but also helps manufacturers comply with stringent regulations regarding product safety and environmental impact.
Animal studies have shown that, when consumed as a food additive, titanium dioxide can induce intestinal inflammation.
The paints and coatings industry reduced their offtakes which coupled with the drop in the crude oil prices and availability of cheaper imports from the Asian market led to the fall in titanium dioxide prices. The demand decreased significantly in the fourth quarter along with the slow manufacturing due to high inflation rates keeping the price trends of the commodity in the negative zone.
Until relevant toxicological and human exposure data that would enable reliable risk assessment are obtained, TiO2 nanoparticles should be used with great care.
Developing new Lithopone formulations, one that enhances the properties of the existing Lithopone is anticipated to boost the demand for Lithopone white pigment during the forecast period. Reinforced Lithopone is one such development, wherein a copolymer is added to the polymerization reaction to yield Lithopone with an increased weather resistance and an anti-ultraviolet property. Moreover, development of nano-scale Lithopone is also anticipated to attract market interest during the forecast period.
Founded in 1902 by Henrick J. Krebs, Krebs Pigments and Chemical Company produced lithopone, a widely used white paint pigment also manufactured by DuPont. But Krebs' company had another asset of special interest to DuPont. ...
