Abstract

The invention discloses a method for preparing hand sanitizer by using willow bark, which comprises the following steps: (1) chopping the vegetative body of bark willow above the ground, drying it, adding ethanol solution and heating it under reflux to extract; Add enough hydrochloric acid to the substance to dissolve it into a transparent solution, then add sodium bicarbonate to it, heat slowly and continue to stir, after keeping warm, centrifuge the mixed solution to obtain the centrifuged supernatant; (3) to the obtained Add mixed alcohols to the centrifuged supernatant, and raise the temperature of the mixture to 40-55°C to prepare the active components of the hand sanitizer. The invention adopts willow to prepare hand sanitizer, the raw material is easy to get, and the price is low, the hand sanitizer prepared is safe and environmentally friendly, has a light fragrance, not only has an extremely excellent decontamination effect, but also can effectively kill hand contamination germs.

Description

technical field [0001] The invention belongs to the field of hand sanitizer preparation, and in particular relates to a method for preparing hand sanitizer by using willow bark. Background technique [0002] Willow bark, also known as goat's milk bar, acanthopanax bark, croissant peach, sheep peach, etc., belongs to the deciduous vine shrub of the romoaceae bark willow. Its characteristics are light-loving, drought-resistant, cold-resistant, saline-alkali-resistant, and the root system is deeply distributed and often clustered. The initial growth diameter is erect, and then gradually creeps or twines, mainly distributed in Northwest, Northeast, North China and Henan, Sichuan, Jiangsu and other provinces. The roots are strong, and a single plant often forms clusters shortly after planting. It has wide adaptability and is an excellent sand-fixing and water and soil conservation tree species; it can relieve pain and remove rheumatism when used as medicine. The root bark of wi...
