Density and speed of sound values of N-lauroyl sarcosine sodium salt (NLSS) and benzethonium chloride (BC) in mixed aqueous mixtures of human serum albumin (HSA) at three equidistant temperatures (298.15, 308.15, and 318.15 K) have been measured. Using density and speed of sound data, various thermodynamic and acoustic parameters like apparent molar volumes (V ϕ), partial molar volumes (V ϕ °), partial molar volumes of transfer (Δtr V ϕ °), dependence of partial molar volume on temperature, Helper’s constant, apparent molar isentropic compressibility (K ϕ,S), partial molar isentropic compressibility (K ϕ,S °), partial molar isentropic compressibility of transfer (Δtr K ϕ,S °), hydration number, and pair–triplet interaction coefficients have been determined. The cosphere overlap model was used to analyze several kinds of molecular interactions present in the studied systems, and it was found that two types of interactions were present in the studied system, i.e., ion–hydrophilic and hydrophilic–hydrophilic interactions. Negative values of Helper’s constant revealed that both NLSS and BC behave as structure breakers.

“…CMC of SDDS decreases abruptly with the increase of MgCl 2 concentration (Figure 1 and Table 1), 27 but in the case of Na 2 SO 4 , the decrease is mild (Figure 2 and Table 2). 28,29 The decrease in the CMC of SDDS in the presence of MgCl 2 is similar to that in the presence of NaCl, 13 but the rate of decrease is abrupt. This fact is due to the higher positive charge density and bigger size of hydrated Mg 2+ compared to Na + .…”

“…It is used as a component of toothpaste as it does not help in the dissolution of tooth enamel and the inhibitory effect of fluoride on the dissolution process . It has several applications in cosmetic formulations such as hair conditioning agent, as well as foaming and cleansing agent used in shampoo, shaving, and wash products because of its soft nature, better biodegradability, antimicrobial property, and stability toward hard water. − SDDS is nonirritating and nonsensitizing to the human skin, and it possesses antimicrobial activities . It should not be used in such cosmetic products where N -nitrososarcosine, a known carcinogen, can be formed.…”

Amino acid-based surfactants are used in academics and industry. Sodium N -dodecanoyl sarcosinate (SDDS) is such an amino acid-based surfactant having applications in pharmaceutical, food, and cosmetic formulations. Although the surface properties of this surfactant have been studied in the presence of univalent cationic and anionic salts, there is no report on such solution in the presence of higher valencies. In this experiment, critical micelle concentration (CMC) of SDDS from tensiometry, conductometry, and fluorimetry has been determined. In each case, CMC decreases with increasing salt concentration. Counterion binding of micelles (β), diffusion coefficient ( D 0 ), and surface properties, e.g., Gibbs free energy for micellization (Δ G m 0 ), Gibbs surface excess (Γ max ), area of exclusion per surfactant monomer ( A min ), surface pressure at CMC (π cmc ), etc., have been evaluated using methods such as tensiometry, conductometry, and fluorimetry. The hydrodynamic radius of SDDS in the presence of different salts was measured by the light scattering method. Aggregation number and shape of micelle have been determined by small-angle neutron scattering experiment. The nature of amphiphilic packing and the aggregation numbers of the assemblies have also been explored. The results from different experiments have been rationalized and represented systematically.

Surfactant systems have been frequently used as pseudomodels for investigating interactions of drugs with biological membranes because of their structural similarities with the latter. This helps to understand complicated yet very important biological processes like diffusion of bioactive moieties through biomembranes. The current study deals with voltammetric and spectroscopic studies to evaluate the interaction of a potential antibacterial drug, gatifloxacin (GTF), with a cationic surfactant, dodecyltrimethylammonium bromide (DTAB), and an anionic surfactant, sodium dodecyl sulfate (SDS), under physiological conditions (phosphate buffer, pH 7.4). For more detailed insight into the GTF–ionic surfactant interactions, density and acoustic data were also recorded and used to calculate several important parameters, namely, apparent molar volume (ɸV), isentropic compressibility (Ks), and apparent molar isentropic compressibility (ɸK) at T = 298.15, 303.15, 308.15, and 313.15 K. Values for partial molar volume (ɸVofalse), partial molar expansivity ()ɸEo, specific acoustic impedance (Z), relative association (RA), intermolecular free length (Lf), and sound velocity number (U) were also obtained. The interpretation of the concentration dependence of the above‐mentioned quantities using a cosphere overlap model led to a better apprehension of solute–solute and solute–solvent intermolecular interactions present in the investigated system, whereas cyclic voltammetry and ultra violet (UV)–visible spectroscopic studies assisted in predicting the location of adsorbed GTF molecules within the DTAB and SDS micelles.
