Surfactants solubilization

This overview will outline surfactant mixture properties and behavior in selected phenomena. Because of space limitations, not all of the many physical processes involving surfactant mixtures can be considered here, but some which are important and illustrative will be discussed these are micelle formation, monolayer formation, solubilization, surfactant precipitation, surfactant adsorption on solids, and cloud point Mechanisms of surfactant interaction will be as well as mathematical models which have been be useful in describing these systems,...

Defoaming agents are in three principal categories, but sometimes are used in combination II) surfactants made soluble. (2) dispersions of hard panicles, and f3) dispersions of soft panicles. The fatty acid-fatty alcohol combination in hydrocarbon oil is an example of a solubilized surfactant defoaming formulation Paraffinic waxes and laity amides may be used in soft-particle formulations. The most common of the hard-particle formulations is silica or a mineral coated with silicone dispersed in a vehicle. A particle size as small as 0.1X2 micrometer may be optimal. [Pg.471]

Formation of solubilized surfactant-latex complexes can influence the properties and performance of vinyl acrylic latexes prepared with NaLS and other penetrating type anionic surfactants. Such complexes seem to affect glass transition temperature and film coalescence process (12). [Pg.232]

Other functionalized surfactants having different complexing groups and modular lipophilic chains, together with various nonionic solubilizing surfactants, are presently under investigation in our laboratories. [Pg.160]

Solubilization. Surfactants are normally used to physically stabilize emulsion droplets against aggregation by providing a protective membrane around the droplet. Nevertheless, there is often enough free surfactant present in an aqueous phase to form surfactant micelles. These surfactant micelles are capable of solubilizing the nonpolar molecules in their hydrophobic interior, which increases the affinity of nonpolar flavors for the aqueous phase. By a similar argument, reverse micelles in an oil phase are capable of solubilizing polar flavor molecules. [Pg.1854]

Figure 1. Structural formulas of the ethoxylated alcohol and phospholipid surfactants used in the affinity precipitation of avidin. Octaethyleneglycol mono-n-dodecylether (C12E8) was used as a solubilizing surfactant and dimyristoylphosphatidylethanolamine (DMPE) was used as the insoluble surfactant to which biotin was covalently attached. (The structural formula of the derivatized phospholipid and a discussion of the reaction and purification scheme have been previously described by Powers et (7)).

Cell membranes may also be affected by solubilizing surfactants, which may dismpt lysosomes, mitochondria, and erythrocytes. Triton X-100 is particularly effective in this respect. Details of these and other effects may be found in the monograph on solubilization by Elworthy, Florence, and MacFarlane (Elworthy,... [Pg.198]
