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.
- Our titanium dioxide products are known for their exceptional whiteness, brightness, and opacity, making them ideal for a wide range of applications. Whether you need titanium dioxide for use in sunscreen, paint, or food coloring, we have the right product for you.
Anyway, it doesn't matter if it reflects or absorbs, Titanium Dioxide is a pretty awesome sunscreen agent for two main reasons: it gives a nice broad spectrum coverage and it's highly stable. Its protection is very good between 290 - 350 nm (UVB and UVA II range), and less good at 350-400 nm (UVA I) range. Regular sized Titanium Dioxide also has a great safety profile, it's non-irritating and is pretty much free from any health concerns (like estrogenic effect worries with some chemical filters).
- Some well-known titanium dioxide food grade suppliers include DuPont, Cristal Global, and Tayca Corporation. These companies have a long history of excellence in the industry and are widely recognized for their commitment to safety, quality, and innovation.
- As the demand for titanium dioxide continues to grow in the plastic and dyeing industries, R218 factory remains committed to providing innovative solutions and high-quality products to meet the evolving needs of its customers. With a strong focus on research and development, the factory continuously explores new applications and formulations for titanium dioxide, ensuring that it remains a versatile and valuable resource for manufacturers around the world.
- When it comes to suppliers, China stands out as the major global producer and exporter of lithopone, accounting for a substantial portion of the world's supply. Chinese suppliers, known for their competitive pricing and large-scale production, have a significant influence on the global market. Companies such as Zhejiang Yinfeng Chemical Co., Ltd., Zhejiang Huayi Chemical Co., Ltd., and Shaanxi Jintai Group Co, and Shaanxi Jintai Group Co
, and Shaanxi Jintai Group Co, and Shaanxi Jintai Group Co

2. What foods contain titanium dioxide?
Titanium dioxide is often used as a UV absorber and pigment in cosmetic products, such as foundations, lipsticks, creams, sunscreens and other skin care products. It helps protect the skin from the harmful effects of UV rays by blocking them, while providing a brightening effect.
- A gravimetric analysis factory is a facility that specializes in the precise determination of the quantity of a substance by weighing the compound or a product containing the substance. In the case of titanium dioxide, the factory uses gravimetric analysis techniques to accurately measure the amount of titanium dioxide present in a sample.
What Is Titanium Dioxide?
Titanium dioxide, also called titania, is an odorless white powder and naturally occurring mineral that is widely used as a pigment for its brightness and whitening effects on a variety of materials, such as paint, plastic, paper, cosmetics, sunscreens, toothpastes and foods.
It’s produced through the sulfate or chloride process, which both involve treating titanium ore with sulfuric or hydrochloric acid to produce titanium sulfate or titanium chloride. These materials are then further processed to remove impurities and produce titanium dioxide in its final form.
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.
Although food-grade titanium dioxide must be 99 percent pure, there’s still a risk of it containing potential contaminants, such as mercury, lead and arsenic. Additionally, inhaling the mineral over time can possibly cause it to build up in your body, leading to adverse effects.
Uses- 3) Metathesis reaction: Dissolve the sulfide in distilled water to obtain a clear decomposition liquid, and add nonionic surfactant to stir evenly, then slowly add it to the zinc sulfate ammonia complex solution to form a metathesis reaction, and obtain Lide powder opacity. The liquid is separated by filtration, and the separated ammonia liquid is returned to the leaching after ammonia adjustment, and the separated nZnS-BaS0 4 crystal filter cake is put into the next step;

Below 20% substitution, it is recommended to replace 1 kg of TiO2 with 1 kg of Lithopone.
Let’s break the risk down further.


A 2022 review on past studies of titanium dioxide and rat lung cancer, for instance, said the original study was under extreme conditions and its effects were not replicated in other animal species. Additionally, the review concluded that the few studies which did directly focus on titanium dioxide's impact on humans did not end up showing any increased cancer risk.
In a study published in the journal Environmental Toxicology and Pharmacology in 2020, researchers examined the effects of food additives titanium dioxide and silica on the intestinal tract by grouping and feeding mice three different food-grade particles — micro-TiO2, nano-TiO2, and nano-SiO2. With all three groups, researchers observed changes in the gut microbiota, particularly mucus-associated bacteria. Furthermore, all three groups experienced inflammatory damage to the intestine, but the nano-TiO2 displayed the most pronounced changes. The researchers wrote: “Our results suggest that the toxic effects on the intestine were due to reduced intestinal mucus barrier function and an increase in metabolite lipopolysaccharides which activated the expression of inflammatory factors downstream. In mice exposed to nano-TiO2, the intestinal PKC/TLR4/NF-κB signaling pathway was activated. These findings will raise awareness of toxicities associated with the use of food-grade TiO2 and SiO2.”
There are two primary forms of titanium dioxide commercially available: anatase and rutile. The rutile form is typically used in sunscreens due to its superior ability to handle UV rays and stability in the presence of UV light. The anatase form is typically used in other types of products, such as paint. Another plus of the rutile form is that its UVA protection extends past 400 nanometers, which is the upper limit of UVA.
From dyes to flavorings, many people are becoming increasingly aware of the ingredients in their food.
