Application of lithopone in rubber and plastics application of lithopone in plastics and pigments lithopone can whiten and improve the compressive strength of products. Lithopone is easy to disperse rapidly, and thus the production process of this product is convenient, especially the molding, injection molding and actual operation process. It is worth mentioning that, with its organic chemical plasticity, it can also be integrated into the vulcanized rubber effect of recycled rubber.

Additionally, the committee noted that the available data did not provide convincing evidence of genotoxicity for titanium dioxide as a food additive, but recognized the limitations in current methodologies with respect to the testing of poorly soluble particulate materials. Although there were uncertainties in the genotoxicity data, the experts took into account the fact that the additive was not carcinogenic in adequately conducted two-year studies in mice and rats at doses of up to 7,500 mg/kg BW per day for mice, and 2,500 mg/kg BW per day for rats, the highest doses tested. There was also no evidence of reproductive or developmental toxicity in studies in rats at doses up to 1,000 mg/kg BW per day, the highest doses tested.

The skin of an adult person is, in most places, covered with a relatively thick (∼10 μm) barrier of keratinised dead cells. One of the main questions is still whether TiO₂ NPs are able to penetrate into the deeper layers of the skin. The majority of studies suggest that TiO₂ NPs, neither uncoated nor coated (SiO₂, Al₂O₃ and SiO₂/Al₂O₃) of different crystalline structures, penetrate normal animal or human skin. However, in most of these studies the exposures were short term (up to 48 h); only few long-term or repeated exposure studies have been published. Wu et al.83 have shown that dermal application of nano-TiO₂ of different crystal structures and sizes (4–90 nm) to pig ears for 30 days did not result in penetration of NPs beyond deep epidermis. On the other hand, in the same study the authors reported dermal penetration of TiO₂ NPs with subsequent appearance of lesions in multiple organs in hairless mice, that were dermal exposed to nano-TiO₂ for 60 days. However, the relevance of this study for human exposure is not conclusive because hairless mice skin has abnormal hair follicles, and mice stratum corneum has higher lipid content than human stratum corneum, which may contribute to different penetration. Recently Sadrieh et al. performed a 4 week dermal exposure to three different TiO₂ particles (uncoated submicron-sized, uncoated nano-sized and coated nano-sized) in 5 % sunscreen formulation with minipigs. They found elevated titanium levels in epidermis, dermis and in inguinal lymph nodes, but not in precapsular and submandibular lymph nodes and in liver. With the energy dispersive X-ray spectrometry and transmission electron microscopy (TEM) analysis the authors confirmed presence of few TiO₂ particles in dermis and calculated that uncoated nano-sized TiO₂ particles observed in dermis represented only 0.00008 % of the total applied amount of TiO₂ particles. Based on the same assumptions used by the authors in their calculations it can be calculated that the total number of particles applied was 1.8 × 10¹³ /cm² and of these 1.4 x10⁷/cm² penetrated. The surface area of skin in humans is around 1.8 m² and for sun protection the cream is applied over whole body, which would mean that 4 week usage of such cream with 5 % TiO₂ would result in penetration of totally 2.6 × 10¹⁰ particles. Although Sadrieh et al.concluded that there was no significant penetration of TiO₂ NPs through intact normal epidermis, the results are not completely confirmative.

Moreover, titanium dioxide is recognized for its non-toxic nature and is generally regarded as safe for use in consumer products. This safety profile allows plastic factories to incorporate TiO2 into items that come into contact with food or bodily fluids, such as medical devices, food storage containers, and children's toys, without posing health risks.

Another important factor to consider when choosing a titanium dioxide supplier is the price. The cost of titanium dioxide can vary significantly depending on factors such as the grade of the product, the quantity purchased, and the supplier's pricing strategy. It is important to strike a balance between quality and price when choosing a supplier to ensure that you are getting the best value for your money.

The properties of lithopone are very suitable for use in the production of coatings. Because the ingredients of lithopone are zinc sulfide and barium sulfate, and the more zinc sulfide content, the stronger its covering power. This indicates a paint product with strong white covering power. It is different from water in that it reacts with acid but does not react with alkali. It has a wide range of uses. Because its structural properties are similar to titanium dioxide and its price is relatively cheap, it can also be used as a substitute for some titanium dioxide. Lithopone can be used for coloring paints, inks, pigments, rubber, paper, leather, enamel, etc.

Lithopone, a crucial ingredient in the world of pigments and coatings, is a blend of zinc sulfide and barium sulfate. It's widely used in various industries due to its exceptional properties, such as high opacity, good whiteness, and heat resistance. Two popular grades of Lithopone are B301 and B311, both with a concentration of 28-30%. This article delves into the significance of these grades and the key suppliers in the market.

In conclusion, lithopone ZnS-BaSO4, as a vital pigment in numerous industries, relies heavily on dedicated and reliable suppliers. Their commitment to quality, innovation, and customer service is paramount in sustaining the growth of this sector. As the demand for cost-effective and environmentally sustainable pigments continues to rise, the role of these suppliers in providing high-quality lithopone will only become more critical in shaping the future of the pigment industry.

The Pivotal Role of Coating Raw Material Manufacturers in Industrial Innovation

Titanium dioxide (TiO2), particularly when engineered into nanoparticles ranging from 30 to 50 nanometers, emerges as a pivotal material in the realm of advanced science and technology. These ultrafine powders exhibit unique properties that are highly sought after in various industries, making their consistent supply crucial for innovation and product development.

The most significant uncertainty identified by the EU experts was the concern that TiO₂ particles may have genotoxic effects. Genotoxicity refers to the ability of a chemical to directly damage genetic material within a cell (DNA), which may lead to cancer in certain situations. Although the experts did not conclude that TiO₂ particles in E171 are genotoxic, they could not rule out the concern that they might be.
