b) Brighteners

Brighteners are the molecules that make the clothes brighter than before by binding themselves to the clothe molecules.

They have a tendency to absorb ultraviolet light and emit visible blue light. This helps in making the clothes brighter as the invisible ultraviolet light is falling on the clothes...
