“…more than one surfactant monomers occupy one adsorption site) when n F >1, and unfavourable (i.e. one surfactant monomer occupy more than one adsorption sites) at n F <1 [53,54]. The value of n F could be fitted using two different power laws, one for each layer.…”

“…for both layers[54], which was sufficient to fit the experimental values. Various trials were conducted using different exponents for each of the layers, but the fitting process (minimization of the sum of the square values of the deviations between the model and the experimental values) led to similar values of n LF for the first and the second surfactant layer.…”

Synopsis Silicone oils have wide range of applications in personal care products due to their unique properties of high lubricity, non‐toxicity, excessive spreading and film formation. They are usually employed in the form of emulsions due to their inert nature. Until now, different conventional emulsification techniques have been developed and applied to prepare silicone oil emulsions. The size and uniformity of emulsions showed important influence on stability of droplets, which further affect the application performance. Therefore, various strategies were developed to improve the stability as well as application performance of silicone oil emulsions. In this review, we highlight different factors influencing the stability of silicone oil emulsions and explain various strategies to overcome the stability problems. In addition, the silicone deposition on the surface of hair substrates and different approaches to increase their deposition are also discussed in detail.

“…These quaternary ammonium Gemini surfactants show a very low CMC values, lower Krafft temperature, better wetting properties, and better ability to lower the surface tension of water in comparison with the corresponding monomeric surfactants. In particular, they can be used as ingredients in cosmetic products [17], as phase transfer catalysts in organic and inorganic reactions [18], and in textile processing [19]. Currently, these surfactants can also be used in medicine as gene delivery agents [20].…”

Novel cationic Gemini surfactant with amide group, N 1 ,N 10 -bis(3-dodecanamidopropyl)-N 1 ,N 1 ,N 10 ,N 10 -tetramethyldecan-1,10-diammonium bromide (abbreviated as 2C 12 enAm) has been synthesized by two-step reactions, purified and characterized in our laboratory. The critical micelle concentration (CMC) values of this Gemini surfactant were determined using electrical conductivity and surface tension measurements in the range of temperatures from 298.15 to 328.15 K. It was observed that the CMC value of Gemini surfactant has a much lower value compared with monomeric ones and shows a slight increase with an increase in the temperature. The interactions between Gemini and conventional monomeric surfactant hexadecyltrimethylammonium bromide (CTAB) have been studied using the conductivity at a certain micellar concentration and temperature range. Rubingh's theory is used to evaluate the micellar interaction parameters (β) for the mixed systems. It has been observed that mixed micelle formation in all the binary mixtures exhibited negative synergism (antagonism) or ideal behavior due to positive β values. Thermodynamics parameters were also obtained from the temperature dependence of the CMC values.From the surface tension measurements, CMC, maximum surface excess concentration at the solution/air interface (Γ max ), minimum area per surfactant molecule (A min ), the surface pressure at CMC (Π CMC ), the surfactant concentration required to reduce the surface tension of solvent by 20 mN m −1 (pC 20 ), and thermodynamic parameters have been evaluated at same temperatures.
