“…Also known as second generation surfactants, they are capable of having diverse applications because of their better solubility, wetability, foaming and dispersion properties (21). Additionally, the hydrophobic chain length and the nature of the spacer also affects the protein-surfactant interactions (22,23). Moorie et al (24) studied the effect of the polar head group on protein-surfactant interactions.…”

Several spectroscopic approaches namely fluorescence, time-resolved fluorescence, UV-visible, and Fourier transform infra-red (FT-IR) spectroscopy were employed to examine the interaction between ethane-1,2-diyl bis(N,N-dimethyl-N-hexadecylammoniumacetoxy)dichloride (16-E2-16) and bovine serum albumin (BSA). Fluorescence studies revealed that 16-E2-16 quenched the BSA fluorescence through a static quenching mechanism, which was further confirmed by UV-visible and time-resolved fluorescence spectroscopy. In addition, the binding constant and the number of binding sites were also calculated. The thermodynamic parameters at different temperatures (298 K, 303 K, 308 K and 313 K) indicated that 16-E2-16 binding to BSA is entropy driven and that the major driving forces are electrostatic interactions. Decrease of the α-helix from 53.90 to 46.20% with an increase in random structure from 22.56 to 30.61% were also observed by FT-IR. Furthermore, the molecular docking results revealed that 16-E2-16 binds predominantly by electrostatic and hydrophobic forces to some residues in the BSA sub-domains IIA and IIIA.

“…In several studies, adenosine triphosphate (ATP) tests were conducted, and alternative practical detergency evaluation methods were implemented [8][9][10][11][12][13], which highlighted the importance of monitoring [14][15][16]. Several fundamental studies were conducted with focus on the interaction of blood proteins such as albumin and hemoglobin with surfactants [17][18][19].…”

In this study, washing tests were performed using samples prepared by contaminating fabrics with hemoglobin, and a kinetic analysis was conducted based the probability density functional method, which expresses the cleaning power using two parameters σ rl (related to the cleaning mechanism) and μ rl (related to the level of cleaning power). This method allows for the processing of uncertainties specific to protein washing under the assumption that the soil adhesion and detergency are in accordance with a normal distribution. A certain amount of hemoglobin solution was soaked in a cloth, dried, and steam-treated, and then used as a sample for a cleaning test. Two parameters σ rl and μ rl were calculated based on the detergency (%) after 5 min, 10 min, 15 min, and 20 min of washing with respect to different pH and temperature levels, and different sodium dodecyl sulfate (SDS) concentration and temperature levels. Based on the results, the value of σ rl indicated that the hemoglobin was removed by the dissolving action. In addition, μ rl increased in accordance with an increase in the pH, SDS concentration, and temperature. With respect to μ rl , the relationship of ΔX + ΔY = Δ(X+Y) was observed in several cases, where ΔX represents the effect of the pH or SDS concentration, ΔY is the temperature effect, and Δ(X+Y) is the combined effect. Therefore, there may be an additive relationship between the pH and temperature effects, and the SDS concentration and temperature effects.

“…Therefore, it is important to investigate the interaction between gemini surfactants and water‐soluble polymers in consideration of their future application in industrial formulations. In the literature about the interaction of gemini surfactant with polymer, reports are mostly about the interaction of gemini surfactants with oppositely charged polymers (Burrows et al, ; Deng, Cao, & Wang, ; Kang, Peng, Liang, Han, & Liu, ; Tardioli, Bonincontro, La, & Muzzalupo, ; Vongsetskul et al, ; Wang, Fan, & Wang, ; Wang & Wang, ; Wang, Yan, Ma, & Li, ; Zana & Benrraou, ) and uncharged polymers (Ali, Suhail, Ghosh, Kamil, & Kabir‐ud‐din, ; Bai, Yujie Wang, Yan, Thomas, & Kwak, ; Kästner & Zana, ; Muzzalupo et al, ; Qiu, Cheng, Xie, & Shen, ; Wang et al, ; Wang, Tang, & Wang, ; Wang & Wang, ; Wettig & Verrall, ), and reports about that of anionic gemini surfactant with anionic polymer are rare (Lai et al, ). Actually, such mixtures are widely applied in enhanced oil recovery.…”

Anionic sulfonate gemini surfactants 8-s-8 (SO 3 ) 2 and 12-s-12(SO 3 ) 2 (s = 3, 6) were synthesized, and their micellization in aqueous solution at 25.0 C and pH 9 was investigated. The results show that the critical micelle concentrations (CMC) of 8-s-8(SO 3 ) 2 are more than 2 orders of magnitude larger than those of 12-s-12(SO 3 ) 2 , but the spacer length has a relatively small impact on the CMC. Moreover, the interactions of n-s-n(SO 3 ) 2 (n = 8, 12; s = 3, 6) with anionic polyacrylamide (PAM) at 25.0 C and pH 9 were investigated using surface tensiometry, rheolgy, and scanning electron microscopy (SEM). The results indicate that the surface tension and rheological properties of PAM depend on the concentration of n-s-n(SO 3 ) 2 . Below the critical aggregation concentration of C 1 , surface tension is sharply reduced, the surface tension of n-s-n(SO 3 ) 2 /PAM is lower than n-s-n(SO 3 ) 2 alone, but viscosity is almost unchanged with increasing C n-s-n(SO3)2 . Above C 1 , surface tension reduces very slowly until the saturated concentration of C 2 is reached. Above C 2 , surface tension rapidly reduces until C M is attained, suggesting free n-s-n(SO 3 ) 2 micelles begin to form. In the region of C 1 -C M , the viscosity significantly increases. Above C M , surface tension is basically unchanged and these curves coincide with those of the single surfactant system. Moreover, the viscosity is almost constant. The SEM images indicate that fibrous aggregates are formed below C 1 , then transformed into multilayer fibrous aggregates above C 1 , and further into fiberbraided-structured and spider-web-structured aggregates above C M . The variation of viscosity is closely associated with the transformation of aggregates.
