Chemical Mechanisms & Reaction Pathways

Optical brightening agents function through fluorescence mechanisms, absorbing UV light and re-emitting it as visible blue light to counteract yellowing and enhance whiteness perception in textile applications.

UV Light Absorption

Absorbs ultraviolet radiation in the 340-370 nm range

Stilbene chromophores provide UV absorption capability
Fluorescence Emission

Re-emits absorbed energy as visible blue light (420-470 nm)

Quantum yield determines emission efficiency
Fiber Substantivity

Forms strong bonds with cellulose and synthetic fibers

Triazine groups provide fiber affinity
