Sodium octyl benzene sulfonate

Many surfactants have been used to formulate microemulsions (1). They were of three types anionic surfactants such as petroleum sulfonates, sodium octyl benzene sulfonate, sodium dodecyl sulfate, alkaline soaps cationic surfactants such as dodecyl ammonium and hexadecyl eimmonium chlorides or bromides and nonionic surfactants such as polyoxyethylene glycols. Furthermore, many exhibit liquid-crystalline properties (2) and in some cases the structure of the mesophases has been established (3). Nevertheless, nearly nothing is known about their compatibility with blood and tissues, and, from our own experience, some exhibit a high lytic power for red cells... 

Fatty acids have a lower solubility in typical ionic detergent solutions than in bile acid solutions, for a given micellar concentration. To paraphrase, the micellar zone in the ternary phase diagram of this system (ionic detergent-fatty acid-water) is smaller than that in the system bile acid-fatty acid-water. Small has constructed the sodium oleate-oleic acid-water phase diagram (32) the micellar zone is extremely small because of the formation of liquid crystalline phases of oleic-sodium oleate at very low oleic acid/ sodium oleate ratios. In unpublished experiments carried out several years ago, we compared the solubility of lauric acid in 40 mM solutions of sodium taurodeoxycholate and sodium glycodeoxycholate with that in sodium octyl benzene sulfonate. Lauric acid at concentrations of 1, 5, and 10 mM was completely soluble in these bile acid solutions at pH 6.3. By contrast, a 5 mM concentration of lauric acid in sodium octyl benzene sulfonate solution was completely turbid. 

For bile salt mixtures, total concentration of bile salts is given. CTAB, cetyl trimethylam-monium bromide HDPC, hexadecyl pyridinium chloride lauryl taurate, sodium lauryl taurate TC-TDC, sodium taurocholate-sodium taurodeoxycholate ABS, sodium p-(H-octyl) benzene sulfonate SIC, a mixture of sodium taurocholate, sodium taurodeoxycholate, sodium taurochenodeoxycholate, sodium glycocholate, sodium glycodeoxycholate, and sodium glycochenodeoxycholate composed to resemble human small intestinal content during fat digestion and absorption (19).

A similar case is mentioned by Heilweil89 who investigated sodium 2,6-di-n-octyl-and sodium 2,6-di-n-dodecylnaphthalene sulfonates in n-decane, n-heptane and benzene. In n-decane the apparent micellar aggregation numbers were essentially independent of C8- and C j 2-chain lengths.
