Surface active agents (surfactants) are amphiphilic materials with a characteristic chemical structure consists of one molecular component that will have little attraction for the surrounding phase, normally called lyophobic group, and a chemical component that have a strong attraction for the surrounding phase, the lyophilic group .In the standard surfactant terminology, the soluble. Surface active agents — Detergents — Determination of cationic-active matter content — Part 2: Cationic-active matter of low molecular mass (between and ) ISO/TC Surface-active agent definition, any substance that when dissolved in water or an aqueous solution reduces its surface tension or the interfacial tension between it and another liquid. See more. Surfactants or surface active agents are a special class of versatile amphiphilic compounds that possess spatially distinct polar (hydrophilic head) and nonpolar (hydrophobic tail) group They show interesting phenomena in solution by modifying the interfacial and bulksolvent - properties.
surface-active agent[′sərfəs ¦aktiv ′ājənt] (materials) A soluble compound that reduces the surface tension of liquids, or reduces interfacial tension between two liquids or a liquid and a solid. Also known as surfactant. surface-active agent 1. In unhardened mixtures of concrete, an additive which has the ability to modify the surface. SURFACE ACTIVE AGENTS A surface active agent (= surfactant) is a substance which lowers the surface tension of the medium in which it is dissolved, and/or the interfacial tension with other phases, and, accordingly, is positively adsorbed at the liquid/vapour and/or at other interfaces. The term surfactant is also applied correctly to sparingly. COVID Resources. Reliable information about the coronavirus (COVID) is available from the World Health Organization (current situation, international travel).Numerous and frequently-updated resource results are available from this ’s WebJunction has pulled together information and resources to assist library staff as they consider how to handle coronavirus. Surface-active molecules concentrate at the areas of contact or interfaces, between oil and water. One end of the molecule seeks oil, while the other end seeks water. At the interface of water and oil, surface-active agents emulsify oil and mix it into the liquid in the same way fat is mixed in milk.
amphiphiles, surface-active agents, tensides, or, in the very old literature, paraffin-chain salts. The term surfactant is now probably the most commonly used and will be employed in this book. This word has a somewhat unusual origin, it was first created and registered as a trade-mark by the General Aniline and Film Corp. for their surface-activeCited by: Additional Physical Format: Online version: Rosen, Milton J. Systematic analysis of surface-active agents. New York, Wiley-Interscience  (OCoLC) Surface Active AgentsPresented by: Sharanjeet Kaur A molecule that contains a polar portion and a non polar portion is called surface active agent/ surfactant.A surfactant can interact with both polar and non polar molecules. A surfactant increases the solubility of the otherwise insoluble substances. In.
