实验目的采用天然草本提取物，更新工艺制备新型洗手液。实验方法主要是超声辅助提取，单因素法。结果发现最优提取条件是超声时间为40min、料液比为1：25，乙醇体积分数为70%且颜色较好。产品粘度为328mpa?s去污能力较高，洗手液1/5000时表面张力小于纯水，pH值6.3皮肤状态最佳，固含量11.7%为正常值。实验研究表明：制备的洗手液符合日常洗手情况[1，2]，功能良好，提取液具天然美肌、无刺激及清香的优点，避免化工洗手液清洗损害皮肤。制备工艺简单，生产成本较低，适于生产、销售。“,”Experiment is the use of natural herbal extracts,Update process for preparing new hand sanitizer.The methods are mainly ultrasonic assisted extraction,single factor.It was found optimum extraction conditions is integrated ultrasonic time 40min,solid-liquid ratio was 1:25,concentration of 70% had better color.viscosity 328 mpa? s,hand soap 1/5000 the surface tension is less than water,the optimum pH of 6.3,a solids content of 11.7% of normal,Moderate foam height 3.2cm.It was showed that hand sanitizer experimental study prepared in line with the daily situation,with good function.Simple preparation process,low production cost.Can production and sale.
