The first commercial production of TiO2 began in the early 20th century, using the sulfate process. This method involved reacting ilmenite ore with sulfuric acid to produce titanium sulfate, which was then calcined to obtain titanium dioxide. However, this process had several drawbacks, including high energy consumption, generation of large amounts of waste, and release of harmful gases such as sulfur dioxide. As a result, many factories transitioned to the chloride process, which offers higher purity TiO2 and reduced environmental impact.

In a study published in 2022 in the journal Particle and Fibre Technology, researchers examined the impact of maternal exposure to titanium dioxide nanoparticles in newborn offspring mice. They found that “a chronic exposure to TiO2 NPs during pregnancy alters the respiratory activity of offspring, characterized by an abnormally elevated rate of breathing.” Breathing was also shown to be “significantly and abnormally accelerated,” and the ability for neural circuitry to effectively adjust breathing rates was impaired. The researchers concluded: “Our findings thus demonstrate that a maternal exposure to TiO2 NPs during pregnancy affects the normal development and operation of the respiratory centers in progeny.”

  • Ponceau 4R, also known as cochineal red, is a natural dye derived from the cochineal insect. It has been used for centuries to add color to foods and beverages, giving them a rich and vibrant red hue. However, one of the main drawbacks of Ponceau 4R is its instability, which can cause the color to fade over time or under certain conditions such as exposure to heat or light.
