4. Consumer Education Agricultural seals play an essential role in educating consumers about food origins and production methods. They encourage consumers to consider the implications of their food choices, such as the environmental impact of certain farming methods. As people become more aware of these issues, they are empowered to make choices that align with their values.

The design of wiper seals is equally important, as it impacts their functionality. There are various designs, including single-lip, double-lip, and integrated scraper seals, each serving specific applications. Single-lip wipers are simple and effective for light-duty applications, while double-lip designs provide enhanced sealing capabilities, making them suitable for more demanding environments.

The additive goes into a lot of personal care products to whiten and brighten colors and to make them opaque, like toothpaste and makeup.

The vitaminB2@TiO₂NPs were obtained at room temperature, by a method developed after trying several ratios of reactants. Briefly, 0.02 g of P25TiO₂NPs were dispersed in 1 mL of ultra-pure water and stirred in a Vortex. Next, 200 μl of vitamin B2 dissolved in ultra-pure water (5.3 × 10⁻³ M) were added to 200 μL of P25TiO2NPs and the mixture was ultrasonicated for 1 hour to achieve a deep-yellow homogeneous suspension. The pellet obtained after centrifuging the suspension for 10 min at 4500 rpm was resuspended in ultrapure water, centrifuged again, and then lyophilized.

Lithopone was discovered in the 1870s by DuPont. It was manufactured by Krebs Pigments and Chemical Company and other companies. The material came in different seals, which varied in the content of zinc sulfide. Gold seal and Bronze seals contain 40-50% zinc sulfide, offering more hiding power and strength. Although its popularity peaked around 1920, approximately 223,352 tons were produced in 1990. It is mainly used in paints, putty, and in plastics.
