Surface Active Agents and Their Health-Promoting Properties: Molecules of Multifunctional Significance [PDF]

open access: yesPharmaceutics, 2020
Surface active agents (SAAs) are molecules with the capacity to adsorb to solid surfaces and/or fluid interfaces, a property that allows them to act as multifunctional ingredients (e.g., wetting and dispersion agents, emulsifiers, foaming and anti ...

Marine-Derived Surface Active Agents: Health-Promoting Properties and Blue Biotechnology-Based Applications [PDF]

open access: yesBiomolecules, 2020
Surface active agents are characterized for their capacity to adsorb to fluid and solid-water interfaces. They can be classified as surfactants and emulsifiers based on their molecular weight (MW) and properties.

Occurrence of Surface Active Agents in the Environment [PDF]

open access: yesJournal of Analytical Methods in Chemistry, 2014
Due to the specific structure of surfactants molecules they are applied in different areas of human activity (industry, household). After using and discharging from wastewater treatment plants as effluent stream, surface active agents (SAAs) are emitted ...

SPERMICIDAL ACTIVITY OF SURFACE-ACTIVE AGENTS [PDF]

open access: yesReproduction, 1962
The spermicidal activities against human spermatozoa of a range of non-ionic, anionic and cationic surface-active agents have been determined with the method of Baker, Ransom & Tynen (1937). Although it has been concluded that surface-tension-lowering properties do not directly influence spermicidal power, the surfacetension/concentration curves of a ...
