The growing interest in substituting synthetic products coming from non-renewable sources with products from biomass has focused attention on the lignin biopolymer. Its high availability, low price and properties make the development of new and valuable uses for lignin interesting, thus improving the economic and environmental aspects of the biomass conversion. To achieve this objective, the potential use of industrial kraft and organosolv lignins as antioxidants, antimicrobials and sunscreen products has been evaluated. The results of a detailed antibacterial and antifungal study demonstrated the high potential of kraft lignins against a variety of foodborne and human pathogenic microorganisms. Moreover, both organosolv and kraft lignins presented an effective protection factor (SPF values from 10-20), demonstrating their effectiveness as natural additives for the sun lotion market. In addition, lignin samples presented high antioxidant capacity compared to butylated hydroxytoluene (BHT), one common commercial antioxidant industrially used. Therefore, the development of innovative applications of lignins as a commodity for the chemical, pharmaceutical or cosmetic industries could expand their possible uses in the market giving new added values to lignin.
用生物质产品替代来自不可再生资源的合成产品的兴趣日益浓厚，这使得木质素生物聚合物受到关注。其高可得性、低价格和特性使得开发木质素新的有价值用途变得有趣，从而改善生物质转化的经济和环境方面。为实现这一目标，已评估了工业硫酸盐木质素和有机溶剂木质素作为抗氧化剂、抗菌剂和防晒产品的潜在用途。一项详细的抗菌和抗真菌研究结果表明，硫酸盐木质素对多种食源性病原体和人类致病微生物具有很高的潜力。此外，有机溶剂木质素和硫酸盐木质素都具有有效的防护因子（防晒系数值为10 - 20），证明它们作为防晒乳液市场天然添加剂的有效性。此外，与工业上常用的一种常见商业抗氧化剂丁基羟基甲苯（BHT）相比，木质素样品具有较高的抗氧化能力。因此，将木质素开发为化学、制药或化妆品行业的商品的创新应用，可能会扩大其在市场上的可能用途，为木质素赋予新的附加值。
