It indicated that the development trend of household detergent would be function, inspissation and liquid-state, and that of surfactants would be oleo-based or other special surfactants, meanwhile more and more attentions should be paid to their security.

指出家用洗涤剂的发展趋势将是功能化、浓缩化和液体化，表面活性剂将向油脂基和特种表面活性剂发展，其安全性也将倍受关注。

Comparing with water, the optimal heat transfer enhancement is achieved near the critical micelle concentrations of surfactants. The degree of heat transfer enhancement is different with different surfactants and is influenced by solubility characteristic, ionic nature and chemical structure of surfactants. Boiling in surfactant solutions, when compared with that in water, is observed to be more vigorous with smaller-sized, more regularly shaped and faster departure frequency bubbles, but the surfactant solutions of Triton X-100 and Triton X-114 become cloudy for the cloud point of surfactants.

和水相比，表面活性剂强化池内核态沸腾换热的最佳浓度为临界胶束浓度；不同种类表面活性剂强化换热程度不同，它们与表面活性剂的溶解特性、离子类型和化学结构有关；溶液沸腾时，沸腾汽泡的脱离直径变小，脱离频率变快和更不易聚集，但非离子表面活性Triton X-100和Triton X-114由于存在浊点其沸腾溶液变浑浊。

Gemini surfactants is especial structure surfactants which have two hydrophile groups and two hydrophobic groups, and traditional surfactants only have one hydrophile group and one hydrophobic group, Gemini surfactants have better and higher surface activity.

双子表面活性剂是具有两个亲水基团和两个亲油基团的一类特殊结构的表面活性剂，比传统表面活性剂(只有一个亲水基团和一个亲油基团)有更高，更好的表面活性。

Compared with conventional surfactants, using the polymeizable surfactants selected from series B or D, some of the latices stabilities are improved. The films made from polymeizable surfactants exhibit a better water resistance than made from conventional surfactants.

相对于传统乳化剂，B、D系列可聚合乳化剂得到的聚合物乳液部分稳定性得到了提高，成膜后的耐水性得到了很大的提高。
