Optical Brightener OB-1 Market – View in Detailed Research Report

Optical Brightener OB-1 (CAS 1533-45-5) is a synthetic chemical compound belonging to the stilbene family, widely used as a fluorescent whitening agent. This bright yellow‑green crystalline powder enhances whiteness and brightness in materials by absorbing ultraviolet light and re‑emitting it as visible blue light. While primarily applied in polyester‑cotton blend textiles, its high thermal stability makes it equally effective for plastics, particularly in injection molding and extrusion processes.
