Prof. Maged Younes, Chair of EFSA’s expert Panel on Food Additives and Flavourings (FAF), wrote of the decision: “Taking into account all available scientific studies and data, the Panel concluded that titanium dioxide can no longer be considered safe as a food additive. A critical element in reaching this conclusion is that we could not exclude genotoxicity concerns after consumption of titanium dioxide particles. After oral ingestion, the absorption of titanium dioxide particles is low, however they can accumulate in the body.”

Both P25TiO2NPs (with or without vitamin B2) were not found beyond the epidermis in 99% of the analyzed TEM images (Fig. 8). This is coherent with previous findings showing that nanoparticles greater than 50 nm can not penetrate the skin, even in vivo models with movement, stretching, and friction [54]. However, in one of the zones, a few nanoparticles were observed inside a hair follicle. This could be due to the follicle exposure after the localized rupture of this physical barrier when rats were shaved in order to clean the area for cream topical administration. This finding suggests that nanoparticle-based sunscreen should not be applied on recently shaved or harmed skin, in order to avoid nanoparticle skin penetration.

  • After the oil seal is positioned in the groove, apply even pressure to the oil seal using a seal driver or a similar tool. This will help to seat the oil seal firmly in the groove and prevent it from moving during use. Make sure to apply the pressure evenly and gently, as applying too much force can damage the oil seal or cause it to deform.

  • The Importance of Spark Plug Valve Cover Gasket in Your Vehicle's Performance
  • One of the key advantages of porcelain spark plugs is their ability to withstand high temperatures. As the spark plug is located inside the combustion chamber, it is exposed to extreme heat during the ignition process. The ceramic material used in porcelain spark plugs can tolerate these high temperatures without degrading, ensuring reliable performance even under strenuous conditions.
  • Gasket rubber seals also play a critical role in the food and pharmaceutical industries, where they are used to create airtight and waterproof seals in packaging materials. This ensures that products remain fresh and free from contamination during storage and transportation This ensures that products remain fresh and free from contamination during storage and transportation This ensures that products remain fresh and free from contamination during storage and transportation This ensures that products remain fresh and free from contamination during storage and transportationgasket rubber seal.

  • In industries like automotive, aerospace, petrochemical, and power generation, where high temperatures and harsh environments are the norm, high temp oil seals are a must-have. For instance, in jet engines, these seals prevent oil leaks that could potentially damage turbine blades or compromise flight safety. In oil refineries, they protect expensive equipment from corrosion caused by exposure to hot oils and chemicals.

  • One of the key benefits of using a U-shaped rubber gasket is its versatility. These gaskets can be used in a wide range of applications, such as sealing doors and windows, connecting pipes, or providing a barrier against moisture and dust. The U shape of the gasket allows it to easily fit into tight spaces and conform to irregular surfaces, making it an ideal choice for sealing applications where traditional gaskets may not be suitable.

  • The metal case is the exterior (or frame) of the oil seal, the principal function of which is to give rigidity and strength to the seal. The material of the case must be selected depending on the environment where the seals are to be used. Often the metal case is covered by the same rubber material used in the sealing element, which also helps seal the exterior of the oil seal in the housing bore. Common case material types are:

  • In conclusion, the U-shaped silicone gasket is more than just a small part; it's a critical element in the complex machinery of modern life. Its importance lies not in its size or visibility but in the essential role it plays in maintaining the integrity and functionality of countless systems. As technology continues to evolve, the significance of this humble gasket will likely only grow, underlining the principle that sometimes, the most effective solutions are the simplest ones.
