基于中药黄芪枸杞的一款抗衰老面膜的制备

以黄芪和枸杞复配提取液制得一款抗衰老面膜.制备过程中,以DPPH自由基清除试验筛选提取液的复配浓度及比例,通过评分法以单因素试验和正交试验对基质配方进行优化,以带液率和保水率为指标筛选面膜基布,并对面膜液进行理化检测及抗氧化性能评价,最后测试面膜的安全性并调查试用效果.结果表明:在面膜基质中添加0.3 g/mL黄芪提取液与0.2 g/mL枸杞提取液以1:2比例复配时,对DPPH自由基的清除率达到最高; 基质中添加0.3%的对羟基苯甲酸甲酯、 0.3%的羧甲基纤维素钠、 5%的甘油时,面膜敷感最为舒适; 纯棉基布作为面膜载体最佳.因该面膜液在理化性质(耐热、耐寒、酸碱度)和安全性等方面符合化妆品的相关标准,且具有良好的抗氧化性能,因此该面膜具有很好的开发利用价值.

Preparation of an anti-aging mask based on traditional Chinese medicine of Astragalus membranaceus and Lycium barbarum extract

Astragalus membranaceus and Lycium barbarum extract that are used as the main active ingredient to make the anti -aging mask. During preparation, selecting concentration and ratio of extract by DPPH test. Formula of fluid is optimized by single factor test and orthogonal test then the mask base fabric is selected with the liquid carrying rate and water retention rate, detect the physical and chemical properties of the mask and evaluate the anti -oxidation performance, finally test the safety of the mask and investigate the trial effect. The results showed that when A.membranaceus extract 0.3 g/mL and L.barbarum extract 0.2 g/mL are compounded at a ratio of 1:2, the scavenging rate of DPPH radical was the highest. The superior formula of fluid is: 0.3% methyl 4-hydroxybenzoate, 0.3% carboxymethyl cellulose sodium, 5% glycerol. Pure cotton base fabric is the best carrier for mask. Because the mask liquid meet the relevant standards of cosmetics in physical and chemical properties(heat resistance, cold resistance, pH value)and safety, and it has good antioxidant properties, so it has good development and utilization value.
