“…The production of foam at the air–water interface for all samples remains stable. As seen previously, and discussed by Wang et al, surface tension can directly correlate to foaming, which can explain why the 1:1 without APG has the best foaming and the 1:3 with APG had the worst foaming because they, respectively, have the lowest and highest surface tension values [15].…”

“…There are other factors that can contribute to foaming properties, like interface dynamics and monolayer interactions in thin liquid films, but they are outside the scope of the study, so the focus remains on surface tension's correlation with foaming. Wang et al discussed the correlation from the perspective of surface energy, demonstrating the generation of foam is due to increasing surface energy [15]. Additionally, lower surface tensions have better surfactant adsorption and the adsorption rate of surfactant molecules on the air–water interface is proportional to foamability [15].…”

“…Wang et al discussed the correlation from the perspective of surface energy, demonstrating the generation of foam is due to increasing surface energy [15]. Additionally, lower surface tensions have better surfactant adsorption and the adsorption rate of surfactant molecules on the air–water interface is proportional to foamability [15]. Short‐term foam stability is important because when applied into personal care products like shampoos and body washes, consumers generally do not use products for an extended period of time and therefore appreciate foaming for the initial few minutes.…”

“…Additionally, surfactant adsorption is known to govern solution foaming properties, which is equally important in terms of sensory performance for the consumer [14]. AOS can have a variety of chain lengths and in a study conducted by Wang et al, the effects of the alkyl chain lengths on interfacial properties at the air–water interface and foamability were investigated [15]. It was determined the longer alkyl chains were unable to efficiently reduce surface tension as well as the shorter alkyl chains, and due to the correlation between foaming and surface tension, the shorter alkyl chains also had better foamability and foam stability when compared to the longer alkyl chains.…”

Objective The main objective of this paper is to analyse the composition of a sulphate‐free binary or ternary surfactant system with alkyl olefin sulfonate (AOS), alkyl polyglucoside (APG) and lauryl hydroxysultaine (Sultaine). The composition was optimized by observing critical parameters such as surface activity and rheological properties while varying the concentration of APG in a ternary system, varying the ratio of AOS and Sultaine in a binary system and studying the effect of sodium chloride addition. The experimental results can provide an alternative, sulphate‐free surfactant system to replace the common system containing sodium laureth sulfate (SLES) and cocamidopropyl betaine (CapB), without compromising on the parameters previously mentioned. Methods A DuNouy Ring was utilized on a tensiometer to measure the surface tension of the samples. To observe foaming abilities of samples, a visual foaming study was conducted and recorded by taking pictures. A TA instruments mechanical rheometer was used to measure the viscosity. Results Studying the effect of APG concentration on surface tension illustrated that as APG concentration decreases, surface tension decreases as well. The minimum surface tension was found to be 26.587 for 7.5 wt.% AOS and 7.5 wt.% Sultaine. When the ratio between AOS and Sultaine changed, the 1:1 system produced the lowest surface tension value again. As the concentration of AOS decreased in the ratio, the surface tension increased. When the ratio was held constant, and APG was introduced into the system, the systems containing APG had higher surface tension values compared with the systems with the same ratios but did not have APG added. As the concentration of salt increased, the surface tension decreased for AOS, increased for the binary mixture and had no effect on Sultaine. Foaming has a direct correlation with surface tension so a decrease in surface tension led to better foaming abilities; therefore, the 1:1 ratio of AOS:Sultaine had the best foaming qualities. The AOS/Sultaine system exhibited Maxwellian behaviour, suggesting the presence of worm‐like micellar structures. As the concentration of APG increased, the viscosity decreased and at a concentration of 2.5 wt.% AOS, 5 wt.% APG and 7.5 wt.% Sultaine, the system changed from shear thinning non‐Newtonian fluid to Newtonian. Varying the ratio of AOS:Sultaine in the binary system, showed as the ratio changed, the viscosity decreased, and at a ratio of 1:3 AOS:Sultaine, the system was primarily Newtonian. As the ratio remained constant and APG was added, the viscosity continued to decrease and the 1:3 ratio was completely Newtonian. The addition of salt had no effect on the viscosity of Sultaine, but the viscosity of AOS increased at a salt concentration of 2 wt.%. The binary mixture saw as the concentration of salt increased, the viscosity profile decreased, even though the system remained non‐Newtonian and shear thinning. Conclusion The surface activity and rheological study of the sulfate‐free surfactant systems u...

Three N‐lauroyl aromatic amino acid surfactants, namely, sodium N‐lauroyl phenylalaninate (SLP), sodium N‐lauroyl tyrosinate, and sodium N‐lauroyl tryptophanate (SLTr), with aromatic group structures were synthesized via methyl ester method. Mass spectrometry, Fourier transform infrared spectroscopy, and nuclear magnetic resonance were applied for the structural representation of products. A comparative study of the three surfactants in terms of surface, foam, and emulsifying properties and decontamination performance was conducted. Results demonstrated that aromatic structure significantly influenced the properties of the three surfactants. SLTr had the best surface performance and foam property, whereas SLP had the best emulsifying property. All three surfactants exhibited strong decontamination effects on protein‐soiled swatches.
