BMM is a high-efficiency optical brightener from the stilbene derivative group, designed to impart superior whiteness and brightness to a variety of substrates. It functions by absorbing invisible ultraviolet (UV) light and emitting visible blue light, which counteracts yellowing and enhances the appearance of whiteness.

BMM is especially suited for detergents, paper, textile, and plastic applications, offering strong whitening effects, excellent chemical stability, and compatibility with both liquid and powder formulations.
