使用毛竹叶提取物为代表原料制定其可能涉及到的各类化妆品三个基本配方体系中的应用性

摘要:随着化妆品向绿色,天然,生态化的发展,植物提取物在化妆品中得到了愈多的研发和利用。所要介绍的竹叶提取物内含天然活性化学成分,对人体皮肤具有优秀的清除皮肤中自由基、抗自由基抗衰老、保湿收敛、防腐、抑菌、美白、消炎等功效。综述其作为新型天然提取物中的有效成分及功效,论文中使用毛竹叶提取物为代表原料制定其可能涉及到的各类化妆品三个基本配方体系中的应用性。设计竹叶提取物添加量分别为0%,2%,4%,6%,8%,10%,15%的浓度梯度在体系中的浓度来深入研究其允许的最大添加量,然后测试不同浓度添加量对体系粘度及pH值的影响,再通过温度稳定性试验、对乳化体系离心实验测试、光稳定性试验(耐光性)测试、对洗涤体系泡沫高度的稳定性和肤感评测来研究其在化妆品中的应用性。47065

Applications of the extract of bamboo leaves in cosmetics

Abstract: With the development of cosmetic directing to green, natural ecology, plant extracts in cosmetics have more research, development and utilization. The bamboo leaf extracts containing natural active chemical components on human skin have excellent eliminating free radicals in the skin, anti-free radical, anti-aging, moisture, convergence, antiseptic, antibacterial, whitening, anti-inflammatory effect and so on. They have been reviewed as the new natural extracts and has the effective composition and efficacy. In this thesis, we used bamboo leaf extract, representing all kinds of cosmetics raw materials involving three formula systems and design bamboo leaf extracts. The adding amount was 0%, 2%, 4%, 6%, 8%, 10%, 15% of the concentration, respectively. These gradient concentrations in the system have been further studied the maximum allowable amount, then we tested the addition ratio of different concentrations on the viscosity and pH value. Next we carried out the temperature stability test, the emulsion system centrifugal experiment, the light stability (light fastness) test, the stability of the foam height in washing system and skin sense to evaluate their applications in cosmetics.

Key Words: bamboo leaf extracts, cosmetic, falconoid, phyllostachys edulis, concentration
