In a lawsuit filed last week, a consumer alleged that Skittles were unfit for human consumption because the rainbow candy contained a known toxin – an artificial color additive called titanium dioxide.
The natural barite containing more than 95% of barium sulfate is mixed with anthracite in a ratio of 3:1 (mass), and is pulverized to a diameter of about 2 cm or less to enter a reduction furnace, and the front stage of the furnace temperature is controlled by 1000 to 1200 ° C, and the latter stage is 500 to 600 ° C, the reduction furnace rotates at a speed of 80s per revolution, the reaction conversion rate is 80% to 90%, the obtained barium sulfide enters the leaching device, the control temperature is above 65 ° C, and the content of barium sulfide is 701%, and then enters the clarification. The barrel is clarified and then added with zinc sulfate to control the zinc sulfate content to be greater than 28%, and the pH is 8-9, and a mixture of barium sulfate and zinc sulfide having a density of
ROS were detected through the colorimetric assay employing the nitro-blue tetrazolium salt (NBT salt) by reading the absorbance of the reduced blue molecule.
According to a 2011 study published in Radiology and Oncology, titanium dioxide may lead to some adverse effects in the body, including oxidative stress, inflammation, and changes in cell signaling pathways. Additionally, pure titanium dioxide can be notably harmful when inhaled.
In food products, E171 is not a singular ingredient; it’s always combined with other ingredients (e.g., proteins and fats) in the food product. Digesting food is a slow process for the body compared to drinking a beverage, which passes much faster through the body.
One of the key advantages of using titanium dioxide in plastics is its ability to improve the mechanical properties of the final product. By adding titanium dioxide to plastic resins, manufacturers can enhance the strength, stiffness, and impact resistance of the plastic, making it suitable for a wide range of applications. Additionally, titanium dioxide helps to reduce the degradation of plastics caused by exposure to UV radiation, thus extending the lifespan of plastic products. Sustainability is at the heart of the factory’s operationsLithopone 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:
Market Dynamics
Suppliers of titanium dioxide for coatings provide manufacturers with the raw material needed to produce high-quality coatings. These suppliers offer different grades and forms of titanium dioxide to meet the specific requirements of various coatings applications. Whether it is for architectural coatings, automotive coatings, or industrial coatings, suppliers of titanium dioxide play a critical role in ensuring that manufacturers have access to the right materials to produce coatings that meet their performance and aesthetic goals. In the plastics industry, TR 92 titanium dioxide is valued for its ability to enhance the brightness and opacity of plastic productsTitanium dioxide (TiO2) is used in a variety of personal care products, including sunscreens, pressed powders, and loose powders, as a UV filter or whitening agent. In lotions and creams (dermal exposure), it is not a risk for adverse health effects. However, when titanium dioxide is inhalable—as it may be when in powder form—it is considered a possible carcinogen by the International Agency for Research on Cancer.Titanium dioxide nanoparticles do not appear to confer any unique health hazards.
Plus, titanium dioxide is chemically inert, meaning it won't react with other substances in the paint. This stability ensures that the paint retains its original color and properties over time, preventing discolouration and degradation. Using titanium dioxide as an ingredient, the paint can withstand harsh weather conditions and prevent flaking, peeling or chalking. This exceptional durability makes it ideal for interior and exterior walls, ensuring a long-lasting and beautiful finish.
In a statement sent to USA TODAY on Sunday, Justin Comes, vice president of research and development for Skittles maker Mars Wrigley North America, said the company couldn't comment on pending litigation – but that its use of titanium dioxide and all Mars Wrigley ingredients are safe and manufactured in compliance with strict quality and safety requirements established by food safety regulators, including the FDA.
Titanium dioxide is a white food coloring agent often used in bakery decorations, soups, broths, sauces, spreads, creamers, candy, and chewing gum.
While IARC listed titanium dioxide as “possibly carcinogenic to humans,” they also add that “there is inadequate evidence in humans for the carcinogenicity of titanium dioxide.” Of the four human studies that they reviewed, only one showed a potential risk for occupational workers inhaling titanium dioxide particles and lung cancer, while the other three showed no risk for cancer at all. And it’s key to note that IARC did not assess the effects of titanium dioxide found in foods.

FDA guidelines:Americans are eating too much salt. So the FDA wants food manufacturers to cut back on sodium.
It's also used in sunscreens as a UV filtering ingredient, helping to protect a person's skin by blocking absorption the ultraviolet light that can cause sunburn and cancer.
Titanium dioxide as used in sunscreens is commonly modified with other ingredients to ensure efficacy and stability. Examples of what are known as surface modifier ingredients used for titanium dioxide include stearic acid, isostearic acid, polyhydroxystearic acid, and dimethicone/methicone copolymer.
In a review published in 2022 in the journal Archives of Toxicology, researchers found that the ingestion of E171 is a “a definite health risk for consumers and their progeny.” After reviewing dozens of in vivo, ex vivo and in vitro studies on the toxicity of E171, the researchers wrote that two facts must be noted: “First, reprotoxicity studies show that animals of both sexes are impacted by the toxicity of these nanoparticles, underlining the importance of conducting in vivo studies using both male and female animals. Second, human exposure begins in utero via maternal-fetal transfer and continues after birth by breastfeeding. Children are then chronically re-exposed due to their food preferences. To be relevant to the human in vivo situation, experimental studies should therefore consider nanoparticle exposure with respect to the age or life period of the studied population.”
