“…In the present work, simulations are performed at a concentration of DS ions close to the critical micelle concentration (CMC). The CMC of the surfactant plays a very important role in removing the dirt from the surface. ,, At the CMC, the micelle formation starts to take place. The contaminants or dirt present on the surface are generally insoluble in water.…”

The hardness-causing ions like calcium are detrimental to the performance of anionic surfactants like dodecyl sulfate. Polystyrene sulfonate is an essential component of ion exchange resins that are used to adsorb such ions. Therefore, understanding the binding behavior of calcium ions to polystyrene sulfonate in the presence of dodecyl sulfate is of industrial relevance. Two important structural parameters of polystyrene sulfonate are known to influence its behavior: (i) The arrangement of aromatic groups around the carbon backbone (tacticity) and (ii) the degree of sulfonation. We use molecular dynamics simulations to study the effect of the above two parameters on the calcium-binding to polystyrene sulfonate in the presence of dodecyl sulfate. We observe that the calcium-binding ability and its response to the dodecyl sulfate are highly sensitive to the arrangement of aromatic groups around the backbone. We identify one atactic structure of 100% sulfonated polystyrene sulfonate and another of 20% sulfonated polystyrene sulfonate that shows a significant increase in calcium ion binding upon the addition of dodecyl sulfate ions. The increase in the 100% sulfonated structure is due to the formation of calcium ion bridges between the sulfonate groups located on one side of the backbone. The increase in the 20% sulfonated structure is due to the increase in the sulfonate-Ca-Cl type of ion bridges. We also observe a stronger association between dodecyl sulfate and low sulfonated polystyrene sulfonate because of the hydrophobic interaction between polystyrene sulfonate's backbone and the hydrocarbon tail of dodecyl sulfate. However, aligning all the aromatic groups on the same side of the backbone (isotactic structure) sharply weakens the association between the two species. Our results can aid in achieving the desired water softening capacity of ion exchange resins in the presence of anionic surfactants via altering the tacticity and degree of sulfonation.

“…“Detergent” is a term that originated from a Latin word called “detergere,” which means to clean or remove (Landeck et al, 2012). Detergents are found in millions of households around the world, and they typically contain surfactants, builders, bleaching agents, enzymes, and fillers (Scott and Jones, 2000) in various proportions.…”

“…Among these ingredients, surface‐active agents or surfactants exert a pivotal role where its cleaning chemistry has been the driving force in detergent innovation for many years (Lafferty, 2010). Surfactants, generally, can be defined as compounds that lower the surface tension of water and possess the wetting, emulsifying, and dispersing properties that enable the removal of stains from fabrics (Landeck et al, 2018; Mukherjee, 2007). Surfactants also can be broadly classified as being anionic, cationic, non‐ionic, and amphoteric or zwitterionic by the charge on the surface‐active component (Gecol, 2006).…”

α-Sulfo fatty methyl ester sulfonate (α-MES) is one of the anionic surfactants that is currently used commercially in the cleaning industry. Although the fundamental studies on α-MES were initiated as far back as the 1950s, it was only recognized as a class of surfactant in the 1980s. In the initial stage of development, α-MES has been associated with many technical impediments, which created a fear factor for the detergent industry to consider this oleobased anionic surfactant for commercial production. However, all the technical adversities have been resolved after five decades of continuous active research and development activities. This paper will review the history, chemistry, process development, processing technologies, performance, commercial production, and applications of oleobased based α-MES with special emphasis on palm oilbased α-MES. The paper also will highlight the challenges and adversities faced by the technology developers and product formulators toward the commercialization of α-MES as an active ingredient in the production of powder and liquid laundry detergents.

In this study, the viscosity and foaming efficiency of amphoteric surfactants on shampoo were investigated and three most commonly used amphoteric surfactants were selected, i.e. Cocamidopropyl betaine (Dehyton KE), disodium coco ampho diacetate (Dehyton DC) and capryl/capramidopropyl betaine (Lirobet 810). Viscosity measurements of amphoteric surfactants were performed in the absence and presence of various concentrations of NaCl at different rates for the prepared shampoo base. The results found in these experiments were compared. It was observed that Cocamidopropyl Betaine amphoteric surfactant gained consistency by using less salt than the other two amphoteric surfactants studied. The best value in itself is the 7% (w/v) cocamidopropyl betaine amphoteric surfactant added to the shampoo base. The foam levels of amphoteric surfactants at different ratios added to the shampoo base studied were also investigated. It has been determined that the best foaming properties is cocamidopropyl betaine for all the amphoteric surfactant studied. The best value in itself is the 10% (w/v) use of cocamidopropyl betaine amphoteric surfactant added to the shampoo base. As a conclusion, cocamidopropyl betaine showed the best performance in terms of foams and thickens with the addition of a small amount of salt.
