“…The micelle aggregation number decreases when n-butanol is added (Table 1), in agreement with the results found for other surfactants (14)(15)(16)(17)(18)(19)(20). This decrease may be explained by considering the various free energy contributions involved in the formation of micelles (34).…”

“…Føreland et al (19) have observed a decrease in the micelle aggregation number of sodium dodecyl sulfate (SDS) micelles at low concentrations of added n-butanol and an increase at higher concentrations of n-butanol. In contrast, no minimum micellar size was noted following addition of n-pentanol or n-hexanol to SDS micelles, and addition of n-propanol produced a continuous decrease in the micelle aggregation number (20). Conflicting results on the influence of n-butanol on SDS were, however, reported from tracer diffusion measurements (21), which indicated that the size of the SDS micelles did not depend on the concentration of this alcohol.…”

“…The effect of added alcohols on the micellar size depends on the hydrophobicity of the alcohol. It is known that short and medium chain length alcohols from methanol to n-butanol at low or moderate concentrations can cause a decrease in the micelle aggregation number in some surfactants (14)(15)(16)(17)(18)(19)(20). Zana and co-workers (14)(15)(16) have shown that addition of alcohols with long hydrocarbon chains such as n-pentanol and n-hexanol may cause a decrease or increase in the micelle aggregation number of tetradecyltrimethyl ammonium bromide (TTAB), depending on the surfactant and alcohol concentration.…”

“…Earlier studies have focused on the structural effects that short chain alcohols and phenols have on SDS complexes. These investigations used small angle neutron scattering (SANS), XRD and pulsed field nuclear magnetic resonance (NMR) [22,23]. In a separate study, the thermodynamic properties of SDS solutions mixed with various short chain alcohols were used to support the hypothesis of a hydrogen bonding interaction between the two components [24].…”

AbstractSodium dodecyl sulfate (SDS) exhibits crystallisation upon exposure to low temperatures, which can pose a problem in terms of product stability. In this study, non-isothermal crystallisation of SDS is investigated via differential scanning calorimetry (DSC) at concentrations that are typical of those present in many industrial liquid detergents. At different low temperatures, the crystal structures are analysed with X-ray diffraction (XRD) and it is concluded that ice formation during the surfactant crystallisation process occurs below 0 °C.The capability of the alcohol precursor, 1-dodecanol, as a seeding material for SDS crystallisation is also investigated through the use of DSC and optical microscopy. These results show that 1-dodecanol can successfully act as a seed for SDS crystallisation. Upon cooling an SDS aqueous system, the crystallisation peak in the DSC thermogram shifts to a higher temperature in the presence of 1-dodecanol. Therefore, any remnant alcohol precursor in surfactant-based formulations could have a negative impact on the product stability upon exposure to cold climates.

“…Zana and coworkers [2][3][4][5][6] have reported extensive studies on the effect of the linear alcohols ethanol to hexanol on the critical micelle concentration (cmc), micelle molecular weight and degree of ionisation. The behaviour of Sodiumdodecyl Sulphate micelles in the presence of n-alcohols has been extensively investigated [7][8][9][10][11][12][13][14]. According to Rubio et al [13] moderately hydrophobic alcohols in low concentration promote micellization probably by residing at the micellar surface and reducing unfavourable water hydrocarbon contacts.…”

A comparative study of Critical Micelle Concentration (CMC) and Free Energy of Micellization of cationic surfactant and anionic surfactant in different composition of methanol-water mixed solvent media by conductometric method at 308.15 K

Precise measurements on the specific conductivity of cationic surfactant (Dodecyltrimethylammonium Bromide) and anionic surfactant (Sodiumdodecyl Sulphate) in methanol-water mixed solvent media containing 0.1, 0.2 and 0.3 volume fractions of methanol are reported at 308.15 K. Specific conductivities of Dodecyltrimethylammonium Bromide and Sodiumdodecyl Sulphate increase with increase in concentration and decrease with increase in the volume fractions of methanol. Critical micelle concentration (cmc) increases with increase in volume fraction of methanol in case of both surfactants. Free energy of micellization (∆Gº m ) has been calculated. Increase in cmc with increase in volume fractions of methanol has been explained in terms of breaking of structure of water due to co-solvent effect.
