Classification of surface active agents: 1. Highly alkaline detergents: 2. Moderately alkaline detergents: 3. Inorganic acids: 4. Organic acids: 5. Surface active agents: a Anionic compounds b Cationic compounds Non ionic surface active compounds Functions of Detergents Surfactants are literally Surface Acting Agents.
They are called this because they act to reduce the surface tension of a liquid, especially water. They are large molecules with two distinct parts. First there is a head which is hydrophilic. This free Medicine essay on Surfactants (surface active agents) is perfect for Medicine students to use as an example.
The classification is intended to provide a clear and logical designation of the structural chemical groups of a surface active agent, in the form of a decimal notation. Its aim is to describe a surface active agent according to its chemical formula. A surfaceactive agent is a substance which lowers the surface tension of the medium in which it is dissolved, lowers the interfacial tension with other phases, and is positively adsorbed at the liquidvapor interface and other interfaces.

99: ISOTC 91: ISO 1063: 1974. Surface active agents Technical alkane sulfonates Determination of the mean relative molecular mass of the alkane Manufacturing bulk surface active agents for use as wetting agents, emulsifiers, and penetrants, andor Manufacturing textiles and leather finishing agents used to reduce tension or speed the drying process.
should be related to the distribution of surface active agent between oil and water under certain conditions. Coalescence rates Consider two oil phases separated by water (Figure 1) and two water phases separated by oil (Figure Surface active agents classification essay, parts of the system formed from oil and water during agitation (Figures 3 and 4).
