| 摘要:木质素分子中富含苯环、酚羟基、羰基、羧基、双键等官能团,具有优异的紫外线防护能力和抗氧化性能,近年来在防晒领域受到广泛关注,有望替代当前防晒产品中矿物或有机合成紫外线防护剂。由于分子结构中缺乏长共轭体系,木质素的紫外吸收主要集中在UVB区域,对UVA波段的防护能力较差,有待于深入研究以提升其整体防护能力。基于此,本文探讨了木质素的特征结构与其紫外防护性能之间的内在联系,综述了提升木质素基防晒霜UVA防护性能的研究策略及进展,展望了木质素在防晒产品中的应用前景,以期为高效安全的木质素基防晒霜开发提供理论参考。 |
| Abstract:Lignin exhibits excellent UV protection and antioxidant properties due to its aromatic structure and the presence of functional groups such as phenolic hydroxyl groups, carbonyl groups, carboxyl groups, and double bonds that have UV absorption capabilities. In recent years, lignin has gained widespread attention in sunscreen research as a promising alternative to the mineral or synthetic organic UV protectants currently used in sunscreen products. The absence of extended conjugated systems in lignin’s molecular structure limits its absorption primarily to UVB radiation, necessitating further research to overcome its poor UVA protection and enhance its overall efficacy as a UV shield. This review summarized the structure-property relationships of lignin in UV resistance performance, with a particular emphasis on strategies and research advances in enhancing its UVA protection. Furthermore, the potential applications and future prospects of lignin in sunscreen products were discussed, providing valuable insights for the development of lignin-based sunscreens. |
