Because of its unique properties, titanium dioxide is widely used and is well known in nanoscience and nanotechnology. Titanium dioxide was one of the first materials to be used in nanotechnology products. However, the potential toxicity of titanium dioxide nanoparticles is a controversial subject. Many cosmetic companies use titanium dioxide nanoparticles. Because of its bright whiteness, it is used in products such as paints, coatings, papers, inks, toothpaste, face powder, and food colouring.

Suppliers of titanium dioxide coatings offer a range of product grades tailored for specific uses. For example, some may be designed for maximum brightness and opacity in paints, while others may be engineered for durability and UV resistance in construction materials. The suppliers must understand the needs of different industries and provide solutions that meet those requirements.
 
However, the China Lithopone B301 market is not without challenges. Environmental regulations, fluctuating raw material prices, and the ongoing global trade tensions have created uncertainties in the supply chain. Nevertheless, Chinese manufacturers have shown resilience by investing in R&D to improve product quality and efficiency, as well as exploring new markets to mitigate risks.

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.

In conclusion, wholesale lithopone B301 factories play a pivotal role in the global pigment industry by supplying a critical component used in numerous manufacturing processes. Their focus on quality, innovation, and sustainability ensures that they will continue to be vital contributors to the sector while balancing the need for economic growth with environmental responsibility.
