The calcined product obtained by the ordinary zinc-barium white preparation method is beaten into a slurry, which is then surface-treated with sodium silicate, aluminum sulfate or sodium aluminate and surfactant, and then filtered, washed, dried and pulverized. Can.
Above 20%, it is recommended to replace 1 kg TiO2 with 1.3 kg of Lithopone 30%.
It's also used in sunscreens as a UV filtering ingredient, helping to protect a person's skin by blocking absorption the ultraviolet light that can cause sunburn and cancer.
Titanium dioxide (TiO2) is commonly applied to enhance the white colour and brightness of food products. TiO2 is also used as white pigment in other products such as toothpaste. A small fraction of the pigment is known to be present as nanoparticles (NPs). Recent studies with TiO2 NPs indicate that these particles can have toxic effects. In this paper, we aimed to estimate the oral intake of TiO2 and its NPs from food, food supplements and toothpaste in the Dutch population aged 2 to over 70 years by combining data on food consumption and supplement intake with concentrations of Ti and TiO2 NPs in food products and supplements. For children aged 2-6 years, additional intake via ingestion of toothpaste was estimated. The mean long-term intake to TiO2 ranges from 0.06 mg/kg bw/day in elderly (70+), 0.17 mg/kg bw/day for 7-69-year-old people, to 0.67 mg/kg bw/day in children (2-6 year old). The estimated mean intake of TiO2 NPs ranges from 0.19 μg/kg bw/day in elderly, 0.55 μg/kg bw/day for 7-69-year-old people, to 2.16 μg/kg bw/day in young children. Ninety-fifth percentile (P95) values are 0.74, 1.61 and 4.16 μg/kg bw/day, respectively. The products contributing most to the TiO2 intake are toothpaste (in young children only), candy, coffee creamer, fine bakery wares and sauces. In a separate publication, the results are used to evaluate whether the presence of TiO2 NPs in these products can pose a human health risk.

Barium sulfide is produced by carbothermic reduction of barium sulfate. Zinc sulfate is obtained from a variety of zinc products, often waste, by treatment with sulfuric acid.
Research supports that applying titanium dioxide to the skin in the form of sunscreens, makeup, and other topical products does not pose any health risks.
Loman Lithopone B311
White power, is a mixture of zinc sulfide and barium sulfate. Its whiteness, strong hiding power than zinc oxide, refractive index and opaque force than zinc oxide and lead oxide.
Applications:
Used for paint, ink, rubber, polyolefin, vinyl resin, ABS resin, polystyrense,polycarbonate, paper, cloth, leather, enamel, etc. Used as a binder in buld production.
Storage:
The product is a kind of white power which is safe, nontoxic and harmless. Keep from misture during transport and should be stored in a cool, dry condition. Avoid breathing dust when handling, and wash with soap & water in case of skin contact. For more details, please refer to the MSDS.
Most food-grade titanium dioxide is around 200–300 nanometers (nm) in diameter. This size allows for ideal light scattering, resulting in the best color (1Trusted Source).
One of the key advantages of using titanium dioxide in rubber is its ability to enhance the whiteness and brightness of rubber products. This is especially important in applications where aesthetic appeal is a priority, such as in the manufacturing of white or light-colored rubber goods. The high opacity of titanium dioxide allows for better hiding power, ensuring a uniform and attractive finish on rubber surfaces.
Company C, a pioneer in the pigment industry, boasts a wide range of Lithopone products, including the B301 and B311 grades. With state-of-the-art manufacturing facilities and strict quality control measures, they guarantee premium quality products that consistently deliver outstanding performance. Chemical resistance is another key property of R1930, making it suitable for use in a wide range of environments. It is resistant to acids, bases, and solvents, which means that it can withstand the conditions often encountered in printing processes. This makes R1930 an ideal choice for inks that will be used in harsh environments, such as outdoor signage or packaging materials that may come into contact with chemicals. Overall, the use of lithopone is crucial in various industries due to its outstanding properties and performance. It is an essential ingredient in paint, rubber, plastic, ceramics, and cosmetics, where it enhances the quality and appearance of the final products. Suppliers play a vital role in providing high-quality lithopone to manufacturers, ensuring the consistent performance of this versatile pigment.
