无患子皂苷及其复配体系的泡沫性能研究

Study on the Foam Properties of Saponins from Sapindus Mukorossi Gaertn and Its Complex System

测定了无患子皂苷的表面活性特征参数,包括HLB值、浊点、酸值、皂化值、临界胶束浓度(CMC)、表面张力值(γcmc)等。研究了无患子皂苷与阴离子、非离子和两性表面活性剂复配后的起泡和稳泡结果,从微观结构上分析了复配体系,为无患子皂苷在洗涤剂配方中的应用提供了理论依据。

The characteristic parameters of saponins from Sapindus Mukorossi Gaertn were determined in this paper, including HLB, cloud point, acid value, saponification value, the critical micelle coneentration（CMC） and the surface tension values （γcmc）. The foam properties of this saponin compounding with anionic, nonionic and amphoteric surfactants were studied. The complex systems were analyzed for their microstructure. The results provide a theoretical basis for the application of saponins from Sapindus Mukorossi Gaerm in detergent formulations.
