Description

Colloidal Lignin Particles (CLPs), with their polyphenolic structure, are promising sustainable alternatives to 
chemical UV filters. This study investigates the photochemical behavior of CLPs under ultraviolet irradiation 
synthetized from five different technical raw lignins (Alkali, Organosolv, two Enzymatic Hydrolyzed and Softwood Kraft Lignin) via solvent-shift procedure. The suspensions were irradiated using a self-developed UV-pen 
set-up and a commercially available UV chamber, enabling controlled UV exposure over time
