Titanium dioxide is widely used as a pigment to provide whiteness and opacity to products such as paints, plastics, papers, inks, foods, and most toothpastes. Its safety as a color additive has been evaluated by several regulatory bodies around the world. In the food industry, it is recognized as safe by the U.S. Food and Drug Administration (FDA) when used in accordance with good manufacturing practices. However, there have been concerns regarding its nanoform; when particles are ultra-small, they might pose health risks if inhaled or ingested over long periods. The European Food Safety Authority (EFSA) reassessed its safety in 2021, expressing concerns about its potential as a genotoxic substance when ingested in high amounts. As a result, the use of titanium dioxide as a food additive has been banned in the European Union starting 2022. It's essential for consumers to be aware of these discussions and make informed choices, especially regarding products intended for ingestion. Nonetheless, for external applications like cosmetics and sunscreens, it continues to be considered safe.
Yes, titanium dioxide is considered safe for use in coloring products, including food, pharmaceuticals, and cosmetics, in many parts of the world. This white pigment is non-toxic and mostly not absorbed into the human body. That said, there have been debates over its safety, primarily relating to its nanoparticle form and potential inhalation risks during its manufacturing process. Most authorities agree that normal, topical or digestive exposure to Titanium Dioxide is safe.
Cellulose paper burns faster because it has a high surface area and is made of organic material that easily combusts when exposed to heat. Cellulosic fibers in the paper provide a ready fuel source for fire, igniting quickly due to the oxygen available between the fibers. Furthermore, the structure of cellulose allows it to break down rapidly under heat, releasing flammable gases that fuel the fire even more. Unlike materials that may melt or decompose slowly under heat, paper's dry, thin nature means it reaches its ignition temperature swiftly, leading to rapid combustion.
