Abstract

This study investigates lignin nanoparticles (LNPs) from spruce and Eucalyptus kraft lignins as sustainable additives for sunscreen formulations. The lignins and their nanoparticles were characterized using spectroscopic, chromatographic, and microscopic techniques and incorporated into oil-in-water sunscreen emulsions, where they were evaluated for UV-blocking efficiency, stability, and rheological properties. Results demonstrated that LNPs significantly enhanced UV protection, with spruce kraft lignin nanoparticles providing superior broad-spectrum coverage (280–400 nm) and an SPF of 12.94, compared to Eucalyptus lignin nanoparticles, which primarily absorbed in the UVB range (280–320 nm) and reached an SPF of 7.00. Additionally, LNPs improved emulsion stability through Pickering stabilization and enhanced rheological properties, making them promising eco-friendly and multifunctional sunscreen additives.

从软木和硬木中提取的木质素纳米颗粒可作为广谱保护和增强防晒性能的可持续添加剂

本研究研究了从云杉和桉树硫酸盐木质素中提取的木质素纳米颗粒（LNPs）作为防晒霜配方的可持续添加剂。利用光谱、色谱和显微技术对木质素及其纳米颗粒进行了表征，并将其掺入水包油防晒乳液中，对其紫外线阻隔效率、稳定性和流变性能进行了评估。结果表明，与主要吸收UVB范围（280-320 nm）的桉树木质素纳米颗粒相比，云杉木质素纳米颗粒具有更强的广谱覆盖（280-400 nm）和12.94的SPF值，显著增强了LNPs的紫外线防护能力。此外，LNPs通过皮克林稳定和增强流变特性改善了乳液稳定性，使其成为有前景的环保多功能防晒添加剂。
