What is optical brightener?

Optical brightener is a kind of fluorescent dye, or white dye, which is a complex organic compound. Its characteristic is that it can excite incident light to produce fluorescence, so that the dyed material can obtain a sparkling effect similar to fluorite, making the material visible to the naked eye very white, achieving a whitening effect.

The principle of the Optical brightener is to convert the invisible ultraviolet radiation absorbed by the product into purple-blue fluorescent radiation, which complements the original yellow radiation to become white light, and improves the whiteness of the product under sunlight. Optical brightener have been widely used in textiles, papermaking, washing powder, soap, rubber, plastics, pigments and paints.
