Fluorescent Brightener 378 (CAS 40470-68-6) is a pale yellow or milky white crystalline powder with a melting point of 216–222°C, a purity of ≥99%, a maximum absorption peak at 368 nm, and a fluorescence emission at 436 nm. This substance belongs to the diphenylethylene-biphenyl class of synthetic fluorescent brighteners. It is primarily used to enhance the whiteness and vibrancy of thermoplastic materials such as polyvinyl chloride (PVC), polypropylene (PP), polystyrene (PS), and ABS. It is particularly suitable for synthetic leather products, as it does not yellow or fade even after long-term storage.
