Sodium decyl sulfate

Sanchez et al. [61,62] studied the stability of sodium decyl, dodecyl, and tetradecyl sulfates and sodium lauryl ether (3 EO) sulfate in acid media (pH 1) at different temperatures and concentrations above and below the critical micelle concentration. Sodium decyl sulfate was shown to be relatively stable for several hours at temperatures up to 90°C. Sodium dodecyl and tetradecyl sulfates were only stable for short periods of time at temperatures above 40-50°C. As expected, sodium lauryl ether sulfate was less stable to hydrolysis than the corresponding lauryl sulfate. 

Shedlovsky et al. studied mixtures of sodium decyl, dodecyl, and tetradecyl sulfates by electromotive force measurements and determined the extent of the dissociation of the sodium counterions by the micelles. From the data obtained strong interaction below the CMC was found for all of the mixtures except those containing more than 25 mol % of sodium decyl sulfate [122]. Commercial alcohol sulfates are mixtures of homologs with different hydrocarbon chains. It has been demonstrated [123] that the CMC of such products is lower than that expected by calculation from the linear relationship between log CMC and the number of carbon atoms of the alcohol as stated in Eq. (11). These results are shown in Fig. 9.

Murthy and Ryan [823] used colloid flotation as a means of preconcentration prior to neutron activation analysis for arsenic, molybdenum, uranium, and vanadium. Hydrous iron (III) oxide is floated in the presence of sodium decyl sulfate with small nitrogen bubbles from 1 litre of seawater at pH 5.7. Recoveries of arsenic, molybdenum, and vanadium were better than 95%, whilst that of uranium was about 75%.

Sodium decyl sulfate, non-ionic surfactants such as polyoxyethyl-ene(20) sorbitan monooleate, and the polymer polyvinylpyrrolidone have been shown to enhance the photobleaching of riboflavin (Kostenbauder and DeLuca, 1963 Kostenbauder et al., 1965). The effects of surfactants and other macromolecules on the rate constants for the photobleaching of riboflavin and acetylriboflavin together with the relative fluorescent...

On the other hand, sodium decyl sulfate, sodium dodecyl sulfate, and a sodium hexadecyl-octadecyl sulfate mixture result in equal PLMA MW for equal surfactant concentrations. These anionic surfactant concentrations are at or above their CMCs. That there is little or no influence on the aggregation number of the mixed micelles as the anionic surfactant tail varies from decyl to octadecyl is an indication of the importance of steric and electrostatic effects in the head-group region in these mixed micelles, at least for the 60 40 nonionic-anionic composition investigated here (34, 35).
