The optical brightening agents (OBAs) market for the textile and cotton industries has witnessed steady growth, driven by the increasing demand for brighter, whiter fabrics and the expanding global textile sector. OBAs are chemical compounds that absorb ultraviolet light and re-emit it as visible blue light, enhancing fabric brightness and offsetting natural yellowing. Production trends indicate a shift toward high-performance, eco-friendly OBAs that are compatible with diverse fibers, including cotton, polyester, and blends. Manufacturers are investing in advanced synthesis processes and high-purity raw materials to ensure superior brightness, wash durability, and fabric compatibility.
