Fluorescent Brightening Agent Detection
topic
Fluorescent brightening agent analysis extracts stilbene, coumarin, and benzoxazole optical brightener types from textile specimens using methanol or dimethylformamide solvent, quantifying by HPLC-DAD with UV detection at 350 nanometres and fluorescence emission at 430 nanometres; screening under UV lamp identifies fluorescent emission characteristic of optical brightener presence before instrumental analysis.
Role
Monitors optical brightener content in white and pastel textiles particularly in infant clothing and medical products where skin sensitisation by topically absorbed UV-activated brightener compounds is a regulatory concern, as certain triazine-stilbene brighteners are restricted under OEKO-TEX baby article product class limits.
