The safety of the food additive E 171 was re-evaluated by the EFSA ANS Panel in 2016 in the frame of Regulation (EU) No 257/2010, as part of the re-evaluation programme for food additives authorised in the EU before 20 January 2009.
Drobne et al. used the terrestrial arthropod Porcellio scaber as a test organism for determining the cytotoxic effect of TiO2 NPs (anatase). The animals were exposed to TiO2 NPs of two different sizes (25 nm and 75 nm) in the concentration range 10–1000 μg TiO2/g dry food for 3 to 14 days. No adverse effects, such as mortality, body weight changes or reduced feeding, were observed. In fact, quite the opposite, an enhanced feeding rate, food absorption efficiency and increase in catalase activity were observed. The intensity of these responses appeared to be time- but not dose-dependent. It should also be noted that the concentrations tested in this study were much higher than the predicted concentration (4.8 μg/g soil) at high emission scenario of nano-sized TiO2. Using the same test organism another group showed that exposure to TiO2 NPs induced destabilization of cell membrane in the epithelium of digestive glands isolated from exposed animals. They also showed that this effect can be observed after just 30 minutes of exposure.
The lithopone manufacturing process typically involves several key steps, including raw material preparation, calcination, grinding, classification, and packaging. Raw materials, primarily zinc sulfide and sulfuric acid, are carefully selected and mixed in a controlled environment to ensure uniformity. The mixture is then fed into a calcination furnace, where it undergoes a high-temperature reaction to produce zinc sulfide.A 2016 review by the European Food Safety Authority concluded that titanium dioxide absorption is extremely low and any absorbed particles are mostly excreted through feces (17Trusted Source).

These insoluble compounds blend well with organic compounds and confer opacity. Lithopone B301, Lithopone B311 powder is famous for the cheap production costs, greater coverage. Related white pigments include titanium dioxide, zinc oxide (zinc white), and zinc sulfide
In conclusion, CAS 13463-67-7, representing 99% pure titanium dioxide powder, is an indispensable raw material pigment across multiple industries. Its versatility, combined with its exceptional optical and protective properties, has made it a go-to choice for formulators and manufacturers seeking to enhance the performance and aesthetics of their products. The bulk availability of this compound underscores its importance in meeting the demands of large-scale production, ensuring a reliable source for global industries.Lithopone is produced by coprecipitation of barium sulfate and zinc sulfide. Most commonly coprecipitation is effected by combining equimolar amounts of zinc sulfate and barium sulfide:
Titanium dioxide, also known as TiO2, is a versatile and widely used white pigment in various industries. Rutile titanium dioxide is considered the best type of titanium dioxide due to its high durability, brightness, and opacity. When looking for a reliable supplier of rutile titanium dioxide, it is important to consider various factors to ensure the quality and performance of the product.Titanium dioxide safety is evaluated by regulatory agencies all over the world based on scientific studies.
In addition to its superior whiteness, TiO2 also offers excellent UV protection. It can absorb and reflect harmful UV rays, protecting materials from degradation and color change. This property is particularly important in outdoor applications, where exposure to sunlight is prolonged. The global titanium dioxide market report provides a comprehensive analysis of the industry, with a focus on key manufacturers in the market. Titanium dioxide is a white pigment widely used in various industries such as paints, coatings, plastics, and cosmetics. The report covers the market trends, growth drivers, challenges, and opportunities for manufacturers in the titanium dioxide industry. One of the key advantages of using cosmetic grade titanium dioxide in cosmetics is its ability to provide a natural-looking finish to products. Titanium dioxide helps to create a smooth and even skin tone, while also providing a matte finish that is long-lasting and resistant to sweat and oil.There are several factors that can influence the cost of titanium dioxide from suppliers. One of the main factors is the availability of raw materials, specifically titanium ore. The cost of extracting and processing titanium ore can fluctuate, which can in turn affect the cost of titanium dioxide. Suppliers must also take into consideration the cost of energy and other resources needed for the production of titanium dioxide, such as labor and equipment. However, China's dominance in rutile titanium dioxide manufacturing is not without challenges
There are numerous manufacturers of titanium dioxide; the largest include Delaware-based Chemours (a spin-off of DuPont Chemical), Texas-based Kronos, and China-based Lomon Billions Group, all of which manufacture pigments for use in products like paints, coatings, and plastics. UK-based Venator is a major supplier of titanium dioxide used in food and cosmetics, along with paints, paper, plastic, and more. As a pigment, it is called Pigment White 6 (PW6), titanium white, or CI 77891. As a food additive, it is known as E171.
