摘要:肌肤清洁是肌肤护理最为重要的一步,不仅能够去除不需要的污垢、油份、皮肤产生的细菌,而且会洗去死亡的表皮细胞,在肌肤清洁时要尽可能减轻对角质层的损伤。采用温和的表面活性剂或乳化剂制备的洗面奶就能做到。利用温和、刺激性低的表面活性剂,特别适用于应用个人清洁护理产品中(例如洗面奶),具有丰富的泡沫和舒适的类似皂基的清洁感。并对实验结果进行讨论及分析。29939
本研究对绿色洗面奶配方设计进行研究,绿色洗面奶的pH值、辅助表面活性剂、聚合物流变 改性剂等因素影响面奶的性能。依据不同温度条件、反应时间考察的结果进行化学分析来得到的。采用以上体系复配的绿色洗面奶稳定性好。并探寻最适宜的配方。

Formulations of green and environment-friendly cleanser
Abstract: Skin cleansing is the most important step in skin care, not only to eliminate the unwanted dirt, oil, bacteria from skin,and will wash away dead skin cells, the skin cleansing should be done to minimize the damage to the cuticle. By adopting a mild surfactant or emulsifier cleanser can do it. Use mild, low irritation, the surfactant, is especially suitable for applications in personal care products(such as facial cleanser), with rich SOAP-like bubbles and comfortable sense of cleanliness. And to discuss and analyze the results.
This research to study the design of green facial cleanser recipe, pH value of green cleanser, factors such as secondary surfactant and polymer rheology modifiers affect the performance of facial cleanser. According to different temperatures and chemical analysis of the results of the investigation to get. Above compound green cleanser system stability.And to search for the most suitable formula.
