- One of the key advantages of TiO2 R605 lies in its multi-purpose nature
- International trade also plays a significant role in China's titanium dioxide industry. The country exports large quantities of titanium dioxide worldwide, making it an important player in the global market. Trade agreements and international relationships are carefully managed to secure export channels and ensure stable supply chains.
- Customer support is another important factor to consider when selecting TiO2 powder suppliers. The supplier should provide responsive and effective support throughout the ordering process, from initial inquiry to final delivery. This includes providing clear communication, addressing any concerns or issues promptly, and offering technical support as needed. A reliable supplier will go above and beyond to ensure that customers are satisfied with their products and services.
- 4. Price While price is an important consideration, it should not be the sole determinant when selecting suppliers. It is essential to find a balance between cost and quality to ensure that products made with ZnS meet performance standards without compromising on quality.
- TiO2, or titanium dioxide, is a highly versatile substance with a wide range of applications, particularly in the concrete industry. A TiO2 concrete factory, therefore, is an industrial facility that specializes in the production of concrete infused with this remarkable compound.
Both P25TiO2NPs (with or without vitamin B2) were not found beyond the epidermis in 99% of the analyzed TEM images (Fig. 8). This is coherent with previous findings showing that nanoparticles greater than 50 nm can not penetrate the skin, even in vivo models with movement, stretching, and friction [54]. However, in one of the zones, a few nanoparticles were observed inside a hair follicle. This could be due to the follicle exposure after the localized rupture of this physical barrier when rats were shaved in order to clean the area for cream topical administration. This finding suggests that nanoparticle-based sunscreen should not be applied on recently shaved or harmed skin, in order to avoid nanoparticle skin penetration.
Titanium dioxide (E 171) is authorised as a food additive in the EU according to Annex II of Regulation (EC) No 1333/2008.
Assessment of skin penetration and biohazard in vivo
Exposure routes are the pathways that allow ingredients to enter our bodies. Primary exposure routes include:
In a 2022 study published in the Journal of Hazardous Materials, scientists wanted to examine the effects of titanium dioxide as a food additive on atherosclerosis in mice. (Atherosclerosis refers to a hardening of the arteries.) Researchers fed mice 40 mg/kg of the food additive every day for 4 months, and found that it not only altered gut microbiota but also led to a significantly increased atherosclerotic lesion area, especially in animals that consumed a high-choline western diet (HCD).
Why Did Europe Ban Titanium Dioxide?
For this reason alone, its time to ditch the Titanium Dioxide & give your skin a break from the relentless free radical damage.
Micronized titanium dioxide doesn’t penetrate skin so there’s no need to be concerned about it getting into your body. Even when titanium dioxide nanoparticles are used, the molecular size of the substance used to coat the nanoparticles is large enough to prevent them from penetrating beyond the uppermost layers of skin. This means you’re getting the sun protection titanium dioxide provides with no risk of it causing harm to skin or your body. The coating process improves application, enhances sun protection, and prevents the titanium dioxide from interacting with other ingredients in the presence of sunlight, thus enhancing its stability. It not only makes this ingredient much more pleasant to use for sunscreen, but also improves efficacy and eliminates safety concerns. Common examples of ingredients used to coat titanium dioxide are alumina, dimethicone, silica, and trimethoxy capryl silane.


The global Lithopone market size was valued at $169.8 million in 2019, and is projected to reach $218.6 million by 2027, growing at a CAGR of 3.3% from 2020 to 2027.
Recent analyses of food-grade TiO2 samples have found that a significant portion of particles may be within the nanoscale. These particles (also known as nanoparticles) range in size from 1 to 100 nm, where 1 nm equals 1 billionth of a metre (the width of a typical human hair is 80,000 to 100,000 nm).
For a review published in 2023 in the journal Environmental Pollution, researchers examined E171 as a possible factor promoting obesity-related metabolic disorders. Because gut microbiota play an important role in immune function maintenance and development, and because titanium dioxide as a food additive has been shown to alter gut microbiota, researchers wanted to review “the dysregulations along the gut microbiota-immune system axis after oral TiO2 exposure compared to those reported in obese or diabetic patients, and to highlight potential mechanisms by which foodborne TiO2 nanoparticles may increase the susceptibility to develop obesity-related metabolic disorders.” The study authors discovered recurrent changes in the gut microbiota composition when exposed to titanium dioxide nanoparticles, with an imbalance of intestinal symbiotic microbiota. These changes and imbalances were also reported and played a role in the development of obesity, the authors wrote. This highlights “foodborne TiO2 nanoparticles as an endocrine disruptor-like chemical promoting obesity-related disorders,” the authors concluded.
