Breathing problems in offspring

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.”

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

What are the forms of titanium dioxide?

In 2023, the demand for titanium dioxide is expected to reach new heights. One of the main drivers of this growth is the cosmetics and personal care industry. Titanium dioxide is widely used in sunscreens, skin care products and cosmetics for its excellent UV protection properties and ability to provide a smooth surface. With growing awareness of the harmful effects of UV radiation, consumers are increasingly inclined to invest in products with sun protection. This trend is expected to drive the demand for titanium dioxide over the next few years.

No. EFSA’s role was limited to evaluating the risks linked to titanium dioxide as a food additive. This included an assessment of relevant scientific information on TiO₂, its potential toxicity, and estimates of human dietary exposure. Any legislative or regulatory decisions on the authorisations of food additives are the responsibility of the risk managers (i.e. European Commission and Member States).
