“…The reduction in the CP value of the TX‐100 + NS system in electrolyte solution follows the order Na 2 SO 4 > NaNO 3 > NaCl at almost all salt concentrations. The results illustrate that the CP values of TX‐100 in the presence of drug decrease with increasing concentration of electrolyte, which is in agreement with the literature (Mudawadkar et al, ).…”

“…Mudawadkar et al () reported that CP of TX‐100 enhances from 336 to 340 K with the augment of the concentration of TX‐100 from 1 to 10 (w/w)%. Normally, CP values of nonionic surfactants vary slowly with the augment of the concentration (Bianco et al, ; Shinoda et al, ).…”

“…The enhancement of CP values beyond 30.9 × 10 −3 mol kg −1 results from the increased micellar surface area as well as the hydration of the surfactant due to an increase in the size of spherical micelle and shape transition of spherical micelle to disk-like at a higher concentration of TX-100 (Ferguson et al, 1985). Mudawadkar et al (2013) reported that CP of TX-100 enhances from 336 to 340 K with the augment of the concentration of TX-100 from 1 to 10 (w/w)%. Normally, CP values of nonionic surfactants vary slowly with the augment of the concentration (Bianco et al, 2010;Shinoda et al, 1963).…”

Cloud point (CP) measurements of 4‐(1,1,3,3‐tetramethylbutyl) phenyl‐polyethyleneglycol (Triton X‐100 (TX‐100)) were performed in aqueous solution in the presence of drug Amikacin sulfate (AS)/Neomycin sulfate (NS)/(AS/NS+ different inorganic salts). In aqueous solution, the CP values of TX‐100 first decrease with increasing concentration and then increase with increasing surfactant concentration. The CP values of TX‐100 solutions were found to increase with the increasing concentration of the AS/NS drug. The CP values of TX‐100‐AS/NS mixtures were also observed to decrease with the increase of the concentration of salt. Different thermodynamic parameters such as standard free energy (normalΔGc0), standard enthalpy (normalΔHc0) as well as the standard entropy (normalΔSc0) change of phase separation were calculated and discussed in relation to molecular interactions.

“…Thus, the investigation of different additives on the physicochemical properties of surfactants in the absence/existence of drugs is important. Other researchers (Mudawadkar et al, ) investigated the phase segregation of TX‐100 in the presence of polyvinyl pyrrolidone (PVP) and reported the elevation of CP values with increasing concentration of TX‐100. The effect of aliphatic compounds and alcohols is also reported (Alauddin et al, ).…”

Conductometric and cloud point (CP) measurement studies have been performed to investigate the interaction of tetradecyltrimethylammonium bromide (TTAB) and Triton® X‐100 (TX‐100) with ciprofloxacin hydrochloride (CFH) in different solvents over the temperature range of 295.15–315.15 K. CFH is used for the treatment of various bacterial infections. The observed critical micelle concentration (CMC) values of TTAB were found to be reduced in the presence of electrolytes (Na2SO4/Na3PO4), and this reduction proceeds with the elevation of salt concentration. The order of the CMC of TTAB follows the trend: cmcH2normalO > cmcNa3PO4 >cmcNa2SO4. The observed CMC values of TTAB were found to increase with increasing temperature and decrease with increasing concentration of CFH in aqueous medium. The values of Gibbs free energy of micellization (∆Gmo) for the TTAB/TTAB + CFH mixture were found to be negative, implying spontaneous micellization. The estimated CP of TX‐100 decreases with increasing concentration of TX‐100 in aqueous medium. The CP values first decrease with increasing concentration of CFH and then increase at higher concentration of CFH almost in all cases investigated. The values of free energy of clouding were found to be positive in all cases studied implying that phase separation of TX‐100 was nonspontaneous. The other thermodynamic parameters associated with the micellization of TTAB and the phase separation of TX‐100 were estimated and explained.

Poly(vinylpyrrolidone) (PVP) is one of the most widely used polymers for numerous biomedical, pharmaceutical, personal care, and industrial applications. This chapter begins with an introduction to the solution properties of PVP as manifested in a number of different important parameters to describe the physicochemical properties of the polymer in aqueous solutions. One of the key features of PVP is its good solubility in both water and organic solvents. The complexation of PVP with polyphenols is the basis for a variety of applications. The generation of binding isotherms provides insight into the interactions between polymers and cosolutes. There is an increasing interest in interpolymer complexes or polymer‐polymer complexes formed by mixing two or more interacting polymers in solution, since they are used to generate multilayered soft nanomaterials, such as self‐assembled films or nanoparticles. There has been significant interest in subcritical and supercritical fluid technology as substitutes for organic solvents.
