(of a substance, such as a detergent) tending to reduce the surface tension of a liquid in which it is dissolved.
（物质，例如清洁剂）表面活性的
some preservatives are inactivated by non-ionic surface-active agents
Example sentencesExamples
Upon separation, the surfactants lose all surface-active behavior.
It has been shown that such interdigitated lamellar phases are formed with soluble surface-active molecules that interact with the polar headgroups of the lipids.
However, the mechanisms promoting transformation of these compact particles into surface-active components is still poorly understood.
These aerosol particles are mainly comprised of organic matter, produced by plankton and are concentrated at the ocean surface due to its surface-active properties.
The presence of a minimum is commonly attributed to surface-active impurities.
The method might also prove highly valuable for the investigation of surface-active substances other than pulmonary surfactant.
Our isotherm results demonstrate that P188 is a highly surface-active copolymer.
If surface tension does contribute significantly, surface-active agents designed to safely and favorably modulate surface tension might be used to increase recoil in emphysema.
Normal pulmonary function requires the presence of a surface-active material at the air/liquid interface of the alveolar hypophase.
This will then allow observing directly the structure-function relationship of pulmonary surfactant and any other surface-active substance.
An important case of adsorption on liquid surfaces is that of surface-active or surfactant molecules at the water-air or water-oil interface.
On the other hand, a haphazard increase in surface tension or selection of a surface-active material with undesirable biological effects could have dangerous consequences.
To weaken the surface of the emulsion droplets and reduce stability, extra emulsifiers such as mono- and diglycerides (small molecule surface-active agents) are added to the emulsion.
For example, changes induced in the capacitance relaxation parameters have been used to help characterize the interaction of surface-active molecules with bilayers.
Such specific interactions may lead to formation of highly surface-active lipid-protein complexes as well as sorting of lipids at the lung air-water interface.
