In mechanical systems, dust seals are frequently found in areas such as wheels, bearings, and hydraulic cylinders. Their design usually features a lip or flange that creates a barrier against particulate matter. By keeping contaminants at bay, dust seals help maintain the integrity of moving parts, extending their lifespan and reducing maintenance costs.

When choosing oil seals, it is essential to consider several key factors that define their quality. First, the material selection is crucial; it should match the specific application requirements, such as temperature resistance, chemical compatibility, and flexibility. Second, the design of the oil seal, which often includes features like lips and grooves, determines its effectiveness in keeping lubricant in and contaminants out. Quality oil seals also exhibit a low rate of wear and excellent reliability over their operational life.

The designation 25% 2035 7 refers to specific dimensions and material characteristics of the oil seal. In the mechanical context, the first number often represents a percentage of the sealing area, while the subsequent figures usually denote the size and type of the seal. The 25% indicates a high sealing efficiency, which is essential for maintaining a controlled environment and minimizing leakage. The numbers 2035 can denote dimensions such as inner and outer diameters or other relevant measurements, emphasizing the oil seal's suitability for particular machinery. Finally, “7” may refer to the design style or material hardness, providing insights into its durability and resistance to wear and tear.

Food safety experts in the European Union (EU) have recently updated their safety assessment of TiO₂ as a food additive. In Europe, TiO₂ is referred to as E171, in accordance with European labelling requirements for food additives. The EU expert panel took into account toxicity studies of TiO₂ nanoparticles, which to this point had not been considered relevant to the safety assessment of TiO₂ as a food additive.  

Titanium dioxide is typically micronized and coated for use in cosmetics products. The micronizing makes this somewhat heavy-feeling ingredient easier to spread on skin, plus a bit more cosmetically elegant. Micronized titanium dioxide is much more stable and can provide better sun protection than non-micronized titanium dioxide.
