- 1. Broad-Spectrum Sun Protection TiO2 is an effective broad-spectrum sunscreen agent, providing protection against both UVA and UVB rays. It helps prevent sunburn, skin aging, and the development of skin cancer.
- Another notable supplier is Company B, who specializes in customized solutions
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, wholesale talc and titanium dioxide are essential minerals that play a crucial role in the cosmetics and pharmaceutical industries. These versatile ingredients offer a wide range of benefits, from absorbing moisture and oil to providing excellent light-scattering properties. By purchasing these minerals in bulk, businesses can save money while ensuring that their products meet the highest standards of quality and safety.
- Color added
- The demand for 30-50nm TiO2 powders stems from their enhanced surface area to volume ratio, which amplifies their reactivity and photocatalytic efficiency. This attribute is paramount in applications such as photovoltaics, where these nanoparticles can boost energy conversion rates in solar cells. In the field of environmental remediation, they serve as potent catalysts for degrading pollutants under light exposure. Furthermore, the exceptional transparency and refractive index of TiO2 nanoparticles make them ideal for high-performance coatings and paints, offering improved durability and aesthetic appeal.

Lithopone, white powder, relative density: 4.136 ~ 4.39 g / mL, insoluble in water. It is a mixture of zinc sulfide and barium sulfate. Inorganic white pigment, widely used in plastics such as polyolefin, vinyl resin, ABS resin, polystyrene, polycarbonate, nylon and polyoxymethylene, and white pigments of paints and inks. It is less effective in polyurethane and amino resins and less suitable in fluoroplastics. It is also used for coloring of rubber products, paper, varnish, tarpaulin, leather, watercolor paint, paper, enamel, and the like. Used as a binder in the production of electric beads.
Australian researchers examined how titanium dioxide as a food additive affected gut microbiota in mice by orally administering it in drinking water. The study, published in the journal Frontiers in Nutrition in 2019, found the treatment could “alter the release of bacterial metabolites in vivo and affect the spatial distribution of commensal bacteria in vitro by promoting biofilm formation. We also found reduced expression of the colonic mucin 2 gene, a key component of the intestinal mucus layer, and increased expression of the beta defensin gene, indicating that titanium dioxide significantly impacts gut homeostasis.” The changes were then linked to colonic inflammation, along with a higher expression of inflammatory cytokines, which are signal proteins that help with regulation. The researchers concluded that titanium dioxide “impairs gut homeostasis which may in turn prime the host for disease development.”
3. Lithopone can be used as a filler for leather and linoleum.

For that reason, the Center for Science in the Public Interest has graded titanium dioxide as a food additive that consumers should seek to “avoid.” Scientists at the nonprofit nutrition and food safety watchdog group today published a new entry for titanium dioxide in its Chemical Cuisine database of food additives.
Resumen–En este artículo se discute el descubrimiento del litopón fosforescente en dibujos a la acuarela por el artista americano John La Farge, fechados de 1890 a 1905, y la historia del litopón en la industria de los pigmentos a finales del Siglo XIX y principios del Siglo XX. A pesar de tener muchas cualidades deseables para su uso en pintura para acuarela o pinturas al óleo blancas, el desarrollo del litopón como pigmento para artistas fue obstaculizado por su tendencia a oscurecerse con la luz solar. Su disponibilidad para los artistas y su adopción por ellos sigue siendo poco clara, ya que por lo general los catálogos comerciales de los coloristas no eran explícitos al describir si los pigmentos blancos contenían litopón. Además, el litopón se puede confundir con blanco de plomo durante el examen visual, y su fosforescencia de corta duración puede ser fácilmente pasada por alto por el observador desinformado. A la fecha, el litopón fosforescente ha sido documentado solamente en otra obra mas: una acuarela por Van Gogh. Además de la historia de la fabricación del litopón, el artículo detalla el mecanismo para su fosforescencia, y su identificación con la ayuda de espectroscopía de Raman, y de espectrofluorimetría.

Overall, the precipitation of titanium dioxide is a complex process that requires careful control of various factors to achieve the desired product properties. By optimizing the precipitation percentage and carefully monitoring the precipitation process, manufacturers can produce high-quality titanium dioxide that meets the stringent requirements of their customers in the paints, coatings, plastics, and cosmetics industries.


Food-grade titanium dioxide differs from what’s added to plastics and paints to enhance whiteness. However, there have been concerns about the environmental impact of titanium dioxide production and the potential health risks from exposure to its particles.
2. Relative density: 4.136 to 4.39 g/mL.
You can find titanium dioxide in products like:
Due to its low binder requirement, lithopone provides paints with good flow and application properties. In the plastic processing industry, it is added to plastics to increase the plastic product’s UV tolerance, thus increasing its outdoor life. In the leather industry, it is one of the sulfide-based white pigments. It is also used in the production of linoleum floorings.
