1. Colorants:
   • Colorants are used to give the scent beads an attractive appearance.
2. Fragrance/Perfume:
   • Fragrance or perfume is a key component of laundry scent beads, responsible for imparting a pleasant aroma to clothes. These fragrances may originate from essential oils, which are encapsulated within tiny microcapsules (known as microencapsulation) to slow down the evaporation of the scent and enhance its durability.
3. Microcapsules:
   • Microcapsules are a core technology in scent beads. They encapsulate fragrance oils within their interiors, releasing the scent only under high temperatures and friction, ensuring long-lasting fragrance on clothes.
4. Other Additives:
   • Depending on the product, it may also contain other functional additives such as antibacterial agents, anti-mite agents, and stain removal agents. Newer generations of scent beads may feature a color-white dual-bead structure, where the colored beads provide softening and fragrance, while the white beads offer antibacterial, anti-mite, and stain removal properties.
