The authority did not identify a safe amount of titanium dioxide that could be consumed.
Further outstanding properties of Lithopone are its high lightness, neutral white colour and its diffuse reflectance in the near UV range.
In a study published in the journal Environmental Toxicology and Pharmacology in 2020, researchers examined the effects of food additives titanium dioxide and silica on the intestinal tract by grouping and feeding mice three different food-grade particles — micro-TiO2, nano-TiO2, and nano-SiO2. With all three groups, researchers observed changes in the gut microbiota, particularly mucus-associated bacteria. Furthermore, all three groups experienced inflammatory damage to the intestine, but the nano-TiO2 displayed the most pronounced changes. The researchers wrote: “Our results suggest that the toxic effects on the intestine were due to reduced intestinal mucus barrier function and an increase in metabolite lipopolysaccharides which activated the expression of inflammatory factors downstream. In mice exposed to nano-TiO2, the intestinal PKC/TLR4/NF-κB signaling pathway was activated. These findings will raise awareness of toxicities associated with the use of food-grade TiO2 and SiO2.”
A piston oil seal, also known as a piston seal ring, is a critical component in an internal combustion engine. It plays a crucial role in preventing oil leakage from the piston and ensuring efficient engine operation.
An oil seal consists of:
Although oil seals have been around for a while, choosing the right one still needs careful planning. If you are sure about the type of seal needed for your application or looking to replace your current seals with custom oil seals that meet your application requirements, then do not hesitate to contact the experts at SSP Seals – a leading industrial seal manufacturer in the USA. The company offers one of the most comprehensive selections of oil seals in the USA in a wide range of materials and profiles such as Type A Single Lip, Type ADL Double Lip, Type AO Single Lip, Type AODL Double Lip, Type B Single Lip Metal Case w/Spring, Type BDL Double Lip, and many more.

In situations where the shaft has splines or an integral gear on the end, you’ll want to take precautions. These gears and splines often have very sharp edges that are quite detrimental to the seal’s integrity. You may use an installation sleeve that will allow the seal to slide past these hazards undamaged.
Oil seals come in various shapes to fit the machine or substance for sealing.
For this reason, when designing a machine, it is important to select the oil seal that is right for that machine.
Next time, we will explain the key points to consider when selecting your oil seal.

While iridium spark plugs may come with a higher price tag compared to copper spark plugs, many car owners find that the long-term benefits outweigh the initial investment. With their superior performance, durability, and efficiency, iridium spark plugs are a smart choice for those looking to get the most out of their vehicle.
When selecting rubber valve cover gaskets, it is important to prioritize quality, durability, and compatibility with the specific vehicle model. High-quality gaskets should be designed to withstand the heat and pressure within the engine, providing a reliable and long-lasting seal. Choosing reputable suppliers and manufacturers known for producing high-quality rubber valve cover gaskets is crucial to ensure the reliability and longevity of these critical components.
Antioxidants: Antioxidant additives work to slow oxidation and the forming of deposits in motor oil. They also help keep the engine clean and extend the life of the motor oil.
