by KeAi Communications Co. The main mechanisms influencing the UV shielding efficiency of LNPs. Credit score: Zhicheng Jiang, et al. Lignin nanoparticles (LNPs) have emerged as promising candidates for enhancing solar safety in cosmetics, providing superior UV-blocking capabilities in comparison with soluble lignin oligomers. Nonetheless, the consequences of the chemical buildings of constituting lignin oligomers
