Yes, many jelly beans are coated with shellac, a natural substance derived from the secretions of the female lac bug found in India and Thailand. Shellac is used to give jelly beans a glossy, shiny appearance, enhancing their appeal. It's labeled as "confectioner's glaze" on ingredient lists. Despite its natural origin, the use of shellac in food products, especially in vegetarian or vegan diets, might be concerning due to its animal-based origin. Consumers seeking plant-based or animal-friendly alternatives might look for jelly beans specifically labeled as vegan or without shellac. There are brands that offer such options, catering to those dietary preferences.
SilverDream prismatic pigments are specialized materials utilized commonly in the cosmetics industry and for automotive paints, among other applications. These pigments are renowned for their ability to refract light, creating a spectrum of colors that change based on the viewing angle. The thickness of these pigments is crucial as it directly influences the color intensity and the shift effect. Typically, these particles are measured in micrometers (µm), with a general range being from 1 to 5 µm. However, the exact thickness can vary depending on the specific application requirements and the desired optical effect. For instance, finer particles might be used in cosmetics for a subtle shimmer, while larger particles might be chosen for a more dramatic color shift in automotive paints. It's important for manufacturers to carefully select the pigment thickness to achieve the desired prismatic effect.
PVC, or polyvinyl chloride, is a versatile plastic with several advantages. Firstly, it's cost-effective, making it a popular choice for a wide range of products, from construction materials to medical devices. PVC is also known for its durability; it's resistant to weathering, chemical rotting, corrosion, shock, and abrasion, which is why it's used in window frames, piping, and outdoor furniture. Additionally, PVC is lightweight, enhancing its use in various applications where weight reduction is crucial. Its low maintenance requirement, coupled with a long lifespan, adds to its appeal. Moreover, PVC can be recycled, reducing its environmental impact. While the recycling rates can improve, its ability to be repurposed into new products underscores its sustainability potential.
