Its chemical structure ensures that the thickener does not react with cationic, anionic or zwitterionic surfactants and emulsifiers and does not require neutralization.

其化学结构确保增稠剂没有反应，阳离子，阴离子或两性离子表面活性剂和乳化剂，并且不需要失效。

Zwitterionic surfactant not only has properties of conventional surfactants, but also has many unique properties, for example, the low toxicity and stimulating to the skin and the eyes, good biologic degradation, basically no social effects of pollution, in addition it is able to bear the hard water and the high concentration electrolyte.

两性表面活性剂不仅具有阴、阳离子表面活性剂的性能，而且具有许多独特之处，例如，低毒性和对皮肤及眼睛的低刺激性，良好的生物降解性，基本上无公害和污染，而且具有耐硬水及高浓度电解质性能。

The results showed that good synergism of all composite systems could be seen, especially the composite systems of anionic/cationic, anionic/zwitterionic surfactants showed better synergism than others.

结果表明：复合体系均体现了一定程度的协同性能，但阴／阳离子型、阴／两性型表面活性剂复合体系的增效协同性能更好。

General meanings, feather and behavior of surfactant, Chemical structure, characteristic and synthesis of anionic, cationic, non-ionic and zwitterionic surfactants, Extraordinary properties and their correlative effecting factors.

阳离子、非离子和两性离子表面活性剂的化学结构、特点和合成方法；同时对表面活性剂的性质及相关因素作一大致的阐述。

Fluorocarbon surfactants,including derivatives of tetrafluoroethylene pentamer,oligo and perfluoroalkyls,were prepared.

由于一般有机液体的表面张力都较低，加入碳氢表面活性剂后，表面张力变化不大，甚至还会升高。

The surfactants used in syndet are mild and high efficiency, little skin irritation. As the pH value of syndet is neutral (7) or skin neutral (5.5), they neither alter the pH of the skin nor cause puffiness skin layer. Due to the absence of lime soap formation there is no problem of skin irritation causedby lime soap residues remaining on the skin.

合成皂所采用的表面活性剂更加温和，对皮肤的刺激性非常小，而且整体呈现中性(7)或者与健康皮肤相近的pH值（5.5），所以对皮肤pH值影响很小，同时避免了长期使用碱性皂引起的皮脂流失，由于没有钙皂形成，避免了钙皂沉积造成的刺激。
