In principle, the iterative experimental approach one would take today is no different than the one pursued by the product developers at Lever Brothers Co. in the early 1950 s, though possibly accumulated data about surfactants, fatty acids, and soaps in the public domain might make ingredient selection some-... 

A controversial problem is still the selection of suitable enhancing agents to overcome the often limited absorption from the colon. In a survey a number of commonly used enhancers, bile salts, surfactants, fatty acids, glycerides, etc. were also reported as effective in the colon [86],... 

Classes of organic compounds analysed by this technique include non ionic surfactants, fatty acids, hydrocarbons (all types), organochlorine compounds, organosulphur and phosphorus compounds, substituted aromatic compounds, NT A, EDTA and insecticides and herbicides. Organometallic compounds studied include those of arsenic, lead, germanium, mercury and tin. 

With both species, small quantities of other hexane-soluble, nonpolar metabolites were Isolated. Some were hydrolyzed In alkali and yielded the respective parent C-surfactants. These metabolites also had very low mobility in reversed-phase (RP) chromatography systems. This suggested they were equivalent to the surfactant fatty acid esters (Figure 1 Ri=fatty acyl, n=5 or 8) whose formation by cell-free homogenates from corn tissues was reported by Frear (11).

AGE monomer is adducted with surfactants/ fatty acids/ or short chain alcohols. 

Extraction of bupivacaine from normal saline was also evaluated using microemulsions composed of Tween-80 and PEG surfactants, fatty acid salts, and ethylbutyrate.

The lattice-controlled diyne polymerization can occur in lipid bilayers only, if the amphiphiles are present in the solid-condensed state. Several studies dealt with the characterization of the monolayer properties of diyne surfactants. Fatty acids, for example, were investigated concerning influences of a chain length variation and headgroup ionization on the Glm stability (Fig. 9a) sv.eo. 62-64,70) number of... 

The micromembrane suppressor makes it possible to detect non-UV-absorbing compounds such as inorganic anions and cations, surfactants, fatty acids, and amines in ion exchange and ion pair chromatography. 

The monoesters are much more soluble in water than the diesters. Like other nonionic surfactants, fatty-acid-free products show excellent compatibility with water-hardness ions. These surfactants show excellent emulsifying properties (w/o or o/w emulsions), superior to the corresponding alkyl ethers. 

The model on which the above derivations are based is by no means unequivocal. There is no proof that micelles diffuse to the surface and adsorb, or, indeed, that hemi-micelles as depicted in Fig. 7.7 form, although Somasundaran et al. [32] have previously postulated their existence. The transfer of solute molecules to the micelle at the surface probably involves complex interactions between surfactant, fatty acid and water perhaps with liquid crystal formation as an intermediate stage following penetration of surfactant molecules. As the earlier steps in the process are not rate limiting their formulation is perhaps less important. Diffusion of the solubilizate4aden micelle is a process which must occur.
