JECFA previously assessed titanium dioxide at its 13th meeting, at which time the expert committee assigned a “not specified” ADI for the additive due to an absence of significant absorption and a lack of toxicological effects in the available experimental animal and human studies. Since its original evaluation by JECFA, titanium dioxide has become a public point of contention, with its ban being introduced (and then subsequently withdrawn) in California legislation in 2023, a legal battle playing out in the EU over the additive’s ban and classification as a carcinogen in 2022, and the European Food Safety Authority (EFSA) calling titanium dioxide unsafe. However, supporters of titanium dioxide say that claims about its dangers are founded in unreliable studies, and some recent research has supported its safety as a food additive.

  • Advantages of Rubber Valve Cover Gaskets

  • One of the main functions of rocker valve cover gaskets is to prevent oil from leaking out of the engine. If the gasket is damaged or worn out, oil can seep out and create a mess under the hood of the car. This not only creates an unsightly appearance but can also lead to engine damage if the oil level becomes too low. Additionally, oil leaks can pose a safety hazard by making the road slippery for other drivers.
  • Gasket rubber seals are typically made from high-quality materials such as neoprene, silicone, viton, and EPDM rubber. These materials offer excellent resistance to chemicals, temperature extremes, and physical stress, making them ideal for use in harsh environments. The seals come in a variety of shapes and sizes, including flat sheets, O-rings, and custom-molded gaskets, allowing them to be used in a wide range of applications.
