Abstract

Lignin, which accounts for 15-35% of the wood components, is being obtained as a by-product in the industrial processes of pulp and in the production of cellulose fuels. It is composed of three main phenyl propane units, p-coumaryl alcohol, coniferyl alcohol, and sinapyl alcohol, which contain a large amount of phenolic hydroxyl groups. In the process of extracting lignin, enzymes and solvents used in each process undergo chemical structural changes during the pretreatment process. Lignin is used in the fields of fine chemicals, polymers, pharmaceuticals and additives, and studies on antioxidant and biological activity are under way. The antioxidative activity of lignin was confirmed by its antioxidant activity, although it depends on the antioxidant activity assay. Several results suggested that lignin should be mixed with conventional antioxidants or synthetic ultraviolet blocking agents rather than using alone. This increases the antioxidant activity and ultraviolet blocking effect by the synergy between lignin and each ingredient. This review described some aspects on a raw material for cosmetics to replace the existing antioxidant raw materials and UV-blocking agents as well as stateof-the-art of lignin research based on literature survey.
