Because of its unique properties, titanium dioxide is widely used and is well known in nanoscience and nanotechnology. Titanium dioxide was one of the first materials to be used in nanotechnology products. However, the potential toxicity of titanium dioxide nanoparticles is a controversial subject. Many cosmetic companies use titanium dioxide nanoparticles. Because of its bright whiteness, it is used in products such as paints, coatings, papers, inks, toothpaste, face powder, and food colouring.

In short, no, research demonstrates that E171 is safe when consumed in normal situations.

Moreover, how we're exposed to an ingredient matters significantly in terms of our health and potential toxicity.   

Research shows that inhaling titanium dioxide particles in significant quantities over time can cause adverse health outcomes. Unless you work in an industrial setting, inhaling substantial amounts of titanium dioxide is highly unlikely. 

Research supports that applying titanium dioxide to the skin in the form of sunscreens, makeup, and other topical products does not pose a health risk. 

Overwhelmingly, research that's relevant to human exposure shows us that E171 is safe when ingested normally through foods and drugs (1,2).

Again, other research suggests that E171 could cause harm; however, those research processes did not design their studies to model how people are exposed to E171. Research that adds E171 to drinking water, utilizes direct injections, or gives research animals E171 through a feeding apparatus is not replicating typical human exposure, which occurs through food and medicine consumption.

  • The primary function of an oil seal is to create a barrier between the rotating or moving parts of a machine and prevent oil or other fluids from leaking out. This helps to ensure that the machinery operates smoothly and efficiently without any loss of lubrication or contamination of the surrounding environment. In addition to preventing leakage, oil seals also help to retain lubricant within the system, extending the life of the equipment.


  • When the bore and shaft centers are misaligned, seal life will be shortened because the wear will be concentrated on one side of the sealing lip.

  • In addition to its functional benefits, the B20 series valve cover gasket also has aesthetic value. A clean and well-maintained engine bay can enhance the overall appearance of a vehicle, and a properly installed valve cover gasket can contribute to this aesthetic appeal.
  • In conclusion, TC oil seals are an indispensable component for maintaining the integrity and efficiency of machinery and equipment. With their superior sealing performance, high-pressure resistance, and long service life, TC oil seals provide the reliability and durability needed for demanding applications. Whether it's sealing oil in an engine or a hydraulic system, TC oil seals deliver excellent performance and peace of mind.

  • Both sealing types are popularly used in different mechanical engineering applications. How are they different? The article explains the fundamental working mechanism of both categories of seals.

  • In the realm of industrial manufacturing, sealing solutions are paramount. Custom molded gaskets, often overlooked as a simple component, play a crucial role in maintaining the integrity and efficiency of equipment and systems. These precision-engineered seals are specifically designed to fit the unique contours and requirements of various applications, ensuring a perfect seal every time.
  • In conclusion, the rotavator oil seal is more than just a small part; it's a guardian of the machine's health and efficiency. Its proper selection, installation, and maintenance are integral to the smooth operation and longevity of the rotavator. Understanding the importance of this seemingly insignificant component can save farmers time, money, and potential setbacks in their agricultural endeavors. So, the next time you engage your rotavator, remember the silent hero – the oil seal – working tirelessly to keep your machinery running at its best.
  • A spark plug is a crucial component in the ignition system of a gasoline-powered engine. It is responsible for igniting the air-fuel mixture in the combustion chamber, which ultimately powers the vehicle. The AM5C spark plug is a specific type of spark plug that is designed to deliver superior performance and durability.
