摘要
为了优化氨基酸洗面奶的发泡能力,以泡沫高度为指标,在单因素实验的基础上,采用4因素3水平的响应面法来优化洗面奶中四种表面活性剂的配比,为洗面奶的开发提供理论依据。响应面结果显示:该款氨基酸洗面奶的最优基质配方为月桂酰肌氨酸钠(LS-30,11 g)、椰油酰胺丙基甜菜碱(CAB,8.6 g)、椰油酰甘氨酸钾(AK-302,18.5 g)、辛癸基葡糖苷(APG0810,5.5 g),洗面奶理论泡沫高度为129 mm。按照最优表面活性剂配比进行三组验证实验,泡沫高度分别为130,131,125 mm,平均值为128.6 mm,与理论值的相对误差仅为0.3%,说明该优化工艺可靠,可以用来优化表面活性剂的配比。按照国家行业标准对洗面奶成品的各项性能进行检测:经过冷热稳定性实验,洗面奶性状无明显变化;运用牛津杯法对洗面奶抑菌性能进行测试,洗面奶对金黄色葡萄球菌、大肠杆菌以及枯草芽孢杆菌有一定的抑制作用;该洗面奶的pH值为6.5;通过有效物含量测试,该洗面奶最终的有效物含量为17.4%。最后,为提高洗面奶的附加功能,在最优配比的基础上添加白芷以及金银花,以初步探究洗面奶开发的可能性。
In order to optimize the foaming ability of amino acid facial cleanser,the response surface method of four factors and three levels was used to optimize the ratio of four surfactants in facial cleanser based on the single factor experiment with foam height as the index,which provided a theoretical basis for the development of facial cleanser.The response surface results showed that the optimal matrix formula of this amino acid facial cleanser was sodium lauroyl sarcosine(LS-30,11 g),coconut amidopropyl betaine(CAB,8.6 g),coconut glycine potassium(AK-302,18.5 g),octyl decyl glucoside(APG0810,5.5 g),and the theoretical foam height of the facial cleanser was 129 mm.Three sets of validation experiments were carried out according to the optimal surfactant ratios,and the foam heights were 130,131 and 125 mm,respectively,with an average value of 128.6 mm,and the relative error with the theoretical value was only 0.3%,which indicates that the optimization process is reliable and can be used to optimize the ratios of surfactants.According to national industry standards,the various properties of facial cleanser products are tested:after cold and hot stability experiments,there is no significant change in the properties of facial cleanser products.The Oxford Cup method was used to test the antibacterial properties of facial cleanser,which showed certain inhibitory effects on Staphylococcus aureus,Escherichia coli,and Bacillus subtilis.The pH value of this facial cleanser is 6.5.Through effective substance content testing,the final effective substance content of this facial cleanser is 17.4%.Finally,in order to enhance the additional functions of the cleanser,Angelica dahurica and Lonicera japonica were added to the optimally formulated cleanser to initially explore the possibility of cleanser development.
