Surfactant detergency

Ion Flotation and Foam Separation. Ions and dissolved surfactant molecules can be removed from solutions by the agency of foam. In this case ions are sandwiched in foam films. The scientific basis of these processes is weU understood and successes of metal ion recovery from solutions including U, Pt, Au, as weU as different surfactants (detergents) have been reported in the Hterature. 

Isopropyl alcohol (IPA) or benzyl alcohol (toluol) often are used in the formulation (as early components in the order of addition) to dissolve the surfactant-detergent base [e.g., Duomeen OL (Akzo Nobel Chemicals, Inc.) or Triton N101 (Union Carbide Corp.)]. 

Polyethylene glycols such as PEG-6 methyl ether may be added as either surfactants, detergents, emulsifiers (to make the dyes and perfumes blend evenly), or thickeners. 

Surfactants (detergents) also help clean the teeth they provide a foam that helps to carry away debris. Moreover, lauryl sulfates have significant antibacterial properties, and they can penetrate and dissolve plaque.

In Scheme 2 D denotes micellized surfactant detergent, S is substrate, subscripts W and M denote aqueous and micellar pseudophases respectively, and /fyj and k are first-order rate constants. The binding constant, Ks, is written in terms of the molarity of micellized surfactant, but it could equally be written in terms of the molarity of micelles. The two constants differ in magnitude by the aggregation number of the micelles.

The magnitudes of these maxima can be decreased almost completely by adding a surfactant to the analyte solution - we call such an additive a current maximum suppresser (or, sometimes, a depolarizer). The usual suppresser employed is Triton X-1(X) (a non-ionic surfactant (detergent)), which is added to the solutions at concentrations of no more than 0.(X)2 mol dm. ... 

Current maximum suppresser A chemical, usually a surfactant (detergent), added to polarography solutions in order to decrease the incidence of polaro-graphic peaks (see Section 6.8.1). 

Disinfectants come from various chemical classes, including oxidants, halogens or halogen-releasing agents, alcohols, aldehydes, organic acids, phenols, cationic surfactants (detergents) and formerly also heavy metals. The basic mechanisms of action involve de-naturation of proteins, inhibition of enzymes, or a dehydration. Effects are dependent on concentration and contact time. 

All molecules that, when dissolved in water, reduce surface tension are called surface-active substances (e.g., soaps, surfactants, detergents). This means that such substances adsorb at the surface and reduce surface tension. The same will happen if a surface-active substance is added to a system of oil-water. The interfacial tension of the oil-water interface will be reduced accordingly. Inorganic salts, on the other hand, increase the surface tension of water.
