“…Therefore, in future works, investigations into the synergies present in surfactant systems and their potential application may need to consider this concentration dependence, especially in cases where micellar structure and interactions need to be controlled. Furthermore, these finding are relevant to the design of multicomponent surfactant systems, extensively employed in a range of formulations, from detergents , to food and pharmaceutical products …”

We investigate the structure and interactions of a model anionic/amphoteric mixed surfactant micellar system, namely, sodium dodecyl sulfate (SDS) and N,N-dimethyldodecylamine N-oxide (DDAO), employing SANS, FTIR, DLS, and pH measurements, in the range 0.1–100 mM total surfactant concentration and 0–100% DDAO. Increasing surfactant concentration is found to elongate the prolate ellipsoid micelles (R Polar ∼ 25–40 Å), accompanied by up to a 6-fold increase in micellar charge. The surfactant synergy, in terms of micellar charge and size, diffusion coefficient, solution pH, and headgroup interactions, was found to vary with concentration. At lower concentrations (≤50 mM), the SDS–DDAO ratio of maximum synergy is found to be asymmetric (at 65–85% DDAO), which is rationalized using regular solution theory, suggesting an equilibrium between Na+ dissociation, DDAO protonation, and counterion concentration. At higher concentrations, maximum synergy shifts toward the equimolar ratio. Overall, our study expands and unifies previous reports, providing a comprehensive understanding for this model, synergetic mixed micellar system.

“…Both also have many similarities regarding their molecular structure and how they clean the surfaces (Nurul Ika Amira, 2015). Practically, after the saponification process is made, which involves heating fats and oils and reacting them with a liquid alkali, the detergent is produced since the saponification process is part of the detergent formulation (Ranji et al, 2019;SDA, 1994;Tareila, 2004). Although people commonly refer to laundry detergent as soap, it differs from soap since there are certain major improvements in the ingredients of detergents.…”

Halal Laundry Detergents: Ingredients and Regulations in Malaysia

Cleaning products are necessary for our daily lives since they are highly effective in cleaning and washing. They assist in personal hygiene by loosening and removing soil and dirt from the surface, diminishing germs or bacteria that are the source of infectious diseases and making the surroundings comfortable. There are three most common detergents in various places: laundry, dishwashing, and household cleaning. Hence, this review paper focuses on laundry detergent to clean the dirt on fabrics and clothes. This paper aims to provide general knowledge for consumers, particularly Muslims, of the ingredients used in laundry detergents and the halal-related regulations in Malaysia. Ingredients used in detergent products, such as enzymes derived from animals, plants, fungi, and bacteria, have issues with where the sources were obtained, which subsequently become one of the reasons many productions have issues fulfilling the halal certification requirement. Other than enzymes, many other ingredients are added to detergent products to provide specific properties and characteristics, such as surfactants, builders, alkalis, bleaches, colourants, and fragrances, which consumers should know before purchasing. Manufacturers must inform Muslim consumers about the purity and impurity of the ingredients used in laundry detergents to make wise decisions in purchasing halal products.

“…The biggest part of the annual production volume of surfactants (46.3 %) is produced for household detergents (Ranji et al, 2019). Sophorolipids can be used as readily biodegradable, non-toxic, biobased, non-irritable, 'green' formulation agents in detergents and cleaning applications.…”
