Benetex OB-1 (1533-45-5) is a heat resistant and chemically stable fluorescent whitener that increases whiteness and provides brighter looking colors. It is used to offset the yellowness of a polymer and to yield a whiter appearance. Optical brighteners create brilliance by a fluorescence process involving absorption of invisible UV light and emission of visible blue light. Benetex OB-1 is especially useful in polyester and nylon fibers, as well as in high temperature engineering plastics.
