Cardanol polyoxyethylene ether(BGF-10)is a kind of nonionic surfactants based on natural raw materials,with good surface activity and resistance to hard water.At 25℃,the value of critical micelle concentration(CMC)is 6.09×10-6mol·L-1,and the lowest surface tension(Γcmc)is 38.08 Mn/m.Moreover,BGF-10 has strong salt tolerance to monovalent inorganic salts; with the increase of concentration of divalent inorganic salt,the surface activity of BGF-10 is enhanced.The effect of monohydric alcohol on the surface activity of BGF-10 is complex: the ability of BGF-10 to form micelles increases and then decreases with the increase of the concentration of monohydric alcohol.BGF-10 has a synergistic effect with anionic,nonionic and cationic surfactants,especially with hexadecyltrimethylammonium bromide(CTAB),and its critical micelle concentration is decreased by 2.52%,while the surface tension is decreased by11.49%.Test results also show,comparing to nonylphenol polyoxyethylene ether(TX-10),the emulsifying and the thickening performances of BGF-10 are better,and its foam performance is lower.Also,the cloud point of BGF-10 is higher than TX-10.In most case,the detergency of BGF-10 is better than or equivalent to TX-10.BGF-10 is an excellent alternative toTX-10in detergents.

随着互联网信息时代的到来，网络营销方式相较于传统的营销方式具有较为明显的优势，迎合了时代发展的需求，发展空间广阔，商品渠道销售模式从传统模式转向网络销售及商家零售混合模式，构成多渠道供应链。在多渠道供应链的模式下存在的价格竞争，难免使制造商和零售之间产生博弈。日化产品作为一种特殊商品，在博弈论视角下，生产商与零售商就多渠道供应链展开策略性合作，对商家在获取利润的过程中，有着很重要的理论指导意义。
以改良的标准洗涤剂配方为基础，用聚氧乙烯蓖麻油酸甲酯(PRAME)全部或部分替代其中的脂肪醇聚氧乙烯醚(9)(AEO9)，配制出一系列液体洗涤剂，测试其耐寒及耐热稳定性，并评价其去污及泡沫性能.结果 表明：所配制的PRAME-AEO9复合洗涤剂配方的耐热和耐寒稳定性均很好，这说明PRAME与配方各组分具有良好的配伍性；在去污力测试实验中，所有配方对三种污布(炭黑污布、蛋白污布、皮脂污布)的去污效果
以脂肪酸甲酯乙氧基化物(FMEE24-09)、脂肪醇聚氧乙烯醚硫酸钠(AES)、碳酸钠(Na2CO3)、硅酸钠(Na2SiO3)、柠檬酸钠(Na3C6H5O7)及二溴海因为主要成分配制鸡蛋粉设备原位清洗系统低泡清洗剂.通过摇瓶泡沫体积法筛选表面活性剂组分的配方量,通过正交试验确定助剂配方量.实验结果表明：当FMEE24-09/AES的质量比为4∶1,总活性物含量为5％,质量分数为0.1％的乳化硅油
在前期实验室合成一种水溶性非离子双子表面活性剂的基础上,本文评价了该表面活性剂的基本性能及在提高石油采收率方面应用的可行性.实验选用浊度法测试了表面活性剂的溶解性,在22℃时该表面活性剂在水中的溶解度为1.0wt％左右.用吊片法测试表面张力,根据表活剂浓度与表面张力关系曲线,确定平衡表面张力约为26mN/m,临界胶束浓度(CMC)为0.02％.该表面活性剂的润湿性能显著,在聚四氟乙烯、石蜡、聚乙烯
以85％脱乙酰度壳聚糖为原料，经气体三氧化硫硫酸化和氢氧化钠中和后提纯得到壳聚糖硫酸钠.采用FT-IR、CP-MAS 13C NMR和元素分析技术对得到的产品结构进行表征，结果表明得到了硫酸酯基取代率为1.75的壳聚糖硫酸钠.通过表面张力、浊度、Zeta电位和透射电子显微镜研究了其与十六烷基三甲基溴化铵(CTAB)复配体系的聚集行为，实验结果表明壳聚糖硫酸钠和CTAB的复配体系具有很高的表面活性和
