Thanaka heartwood, which was biomass waste after using the bark of thanaka, was recycle-used for thanaka cellulose films and then applied for cosmetic facial masks. The thanaka heartwood composed of cellulosic fibers and the ordered whewellite (hydrated calcium oxalate) was chemically treated, and the processes could remove lignin, hemicelluloses, whewellite, and others successfully by using acid (H₂SO₄), alkali (NaOH) and sodium hypochlorite (NaOCl). Dimethylacetamide/lithium chloride (DMAc/LiCl) solution was used to dissolve the thanaka cellulose fibers, and then cellulose hydrogel films having transparent and flexible were prepared. Antimicrobial activities of cellulose solutions were tested for the purpose of using thanaka cellulose films for facial masks. From those observations, thanaka cellulose hydrogel films and facial masks are potential to be environmental friendly and biocompatible products.This article also has reviewed cellulosic hydrogels for uses of cosmetic application.

塔纳卡心材是利用塔纳卡树皮制成的生物质废料，可回收利用来用于塔纳卡纤维素膜，然后用于化妆品面膜。化学处理纤维素纤维和有序的纤锌矿（水合草酸钙）组成的thanaka心材，该工艺可以成功地使用酸（H ₂ SO _4）去除木质素，半纤维素，纤锌矿等。），碱（NaOH）和次氯酸钠（NaOCl）。使用二甲基乙酰胺/氯化锂（DMAc / LiCl）溶液溶解坦卡纤维素纤维，然后制备具有透明且柔性的纤维素水凝胶膜。测试了纤维素溶液的抗菌活性，目的是将thanaka纤维素薄膜用于面膜。从这些观察结果来看，thanaka纤维素水凝胶薄膜和面膜可能是环保和生物相容性产品。本文还对纤维素水凝胶在化妆品中的应用进行了综述。
