A model-based rheological characterization of four sphingans in combination with four prominent surfactants of cosmetic formulations of cationic, anionic, zwitterionic and neutral headgroup characteristics was performed. The impact of the surfactants on the rheological properties, based on changes in the mechanical models was evaluated in respect to the closely related structural differences of the polysaccharides, to give an insight on the structure-function relationship of these interactions. The side chains of the sphingans Welan, Diutan and S-88 seem to be involved in the masking of the anionic charge of the polysaccharide backbone, making them highly compatible even with cationic surfactants. The effect of a disaccharide side chain of Diutan also impacts its intermolecular interactions opposed to Welan and S-88, resulting in different surfactant interactions as well as temperature stability. The lack of a side chain in Gellan leads to large incompatibilities with zwitterionic and cationic surfactants due to high polysaccharide-surfactant interactions.

基于模型的流变学表征了四个鞘氨醇与四种主要的阳离子，阴离子，两性离子和中性头基特性化妆品配方的表面活性剂。针对多糖的紧密相关结构差异，评估了基于力学模型变化的表面活性剂对流变性能的影响，从而深入了解了这些相互作用的结构-功能关系。鞘氨醇Welan，Diutan和S-88的侧链似乎参与了多糖主链阴离子电荷的掩蔽，使其即使与阳离子表面活性剂也高度相容。Diutan的二糖侧链的作用也影响了与Welan和S-88相反的分子间相互作用，导致不同的表面活性剂相互作用以及温度稳定性。由于高的多糖-表面活性剂相互作用，结冷胶中缺乏侧链会导致与两性离子和阳离子表面活性剂的巨大不相容性。
