What is optical brightener ?

They reduce the perceived yellow/orange color of naturally yellow/orange materials by making up for the material's lack of blue and purple light reflection with the fluorophore's blue and purple optical emission.

Optical brightener uses ?

Optical brighteners use ultraviolet (UV) light waves to boost blue light and reduce yellow light, making things look whiter.
