Preparation and properties of Ginkgo Biloba leaves extract amino acid cleaning paper soap
Amino acid surfactant products are favored by the market due to their low irritation and high environmental protection.In order to prepare amino acid surfactant products with antioxidant and antibac-terial effects,Ginkgo biloba leaves extract was prepared by using Ginkgo biloba leaves as raw materials and ethanol-water as extractant.Then,the extract was compounded with amino acids to prepare amino acid cleansing paper soap containing Ginkgo biloba extract(referred to as paper soap),and its physical and chemical properties,antioxidant properties and antibacterial properties were studied.The results showed that the optimal extraction process was as follows:extraction time of 10 min,ethanol volume frac-tion of 60％,extraction temperature of 70 ℃,solid-liquid ratio of 1∶30(g/mL),and the extraction rate reached to 3.76％.The mass fractions of Chloride,water volatile substances,phosphates,and total ef-fective substances in the produced paper soap were 0.016％,13.8％,0.00％,and 73.7％,respective-ly,all of which met the national standards.The pH value of the paper soap is close to that of human skin,which is weakly acidic,and the foaming power is above 500％.It has certain DPPH(1,1-di-phenyl-2-trinitrophenylhydrazine)free radical scavenging ability and antibacterial ability.The self-made paper soap not only has excellent physical and chemical properties,but also has antibacterial and antioxi-dant functions.
