碩士 / 萬能科技大學 / 化妝品應用與管理研究所 / 106 / Luteolin is a natural flavonoid which is present in a variety of plants and has antioxidant, anti-inflammatory and antibacterial properties. However, trehalose is a non-reducing disaccharide molecule that exists in nature and is used to maintain cell viability. In the preparation of cosmetics and pharmaceuticals, it is an important component of moisturizing cosmetics. In this experiment, the first stage product was synthesized by using luteolin and propylene glycol and a catalyst, and then the polyethylene glycol (PEG400, 600, 1000, 2000) with good dispersibility was synthesized as the hydrophilic segment and succinic anhydride. The second stage product is then added to the second stage product for synthesis, and finally trehalose is added to the final product to obtain a series of water soluble polyphenol/glucose surfactants. The synthesized product was analyzed by infrared spectroscopy (FT-IR), and the surface tension of the water-soluble luteolin/trehalose surfactant was measured by a surface tension meter. The particle size analysis and the interfacial potentiometer were used to test the emulsification performance of the synthesized product. The dyeing test is carried out, and the designed new surfactant has good interfacial activity, can increase the wettability of the wool, and exerts a good leveling effect in the low temperature dyeing of wool.
