This study examines the carbon's chain length of alkyl propoxylated sodium sulfate anionic surfactants (C16O(PO)15S, C14O(PO)15S, and C12O(PO)15S) mixed with a nonionic ethoxylated surfactant on viscoelastic properties and interfacial tension. Results show that the larger the surfactant's carbon chain, the greater the possibility of forming WM. Furthermore, the propylene oxides' (PO) number and the nonionic surfactant's type of tail (linear or branched) is studied, not only on WM formation but also on WM/crude interfacial tension values. It is observed that the surfactant's molecular structure plays an important role in WM formation. By increasing the anionic surfactant's PO from 15 to 20 units, the maximum value of zero viscosity goes from 4.507 to 0.092 Pa.s and by changing the structure of the nonionic surfactant from linear (C12-13EO8) to branched (C12-14EO9) keeping the PO number of the extended surfactant constant, the zero viscosity value goes from 4.507 to 0.28 Pa.s.

Herein, four new non-ionic Gemini surfactants with different spacers were designed and synthesized, and their surfactant properties and biodegradability were studied. The synthesis of these compounds involves a two-step procedure. The first step is the formation of an amide from lauric acid and diethanolamine. The second step is the reaction of lauryl diethanolamide with four different spacers, the latter being flexible-hydrophilic, and rigid-hydrophobic in structure, respectively. Their structures were characterized using 1H NMR, 13C NMR, FT-IR, and ESI-MS. The critical micelle concentration (CMC), the surface tension at CMC (γCMC), the efficiency of these compounds to reduce the surface tension by 20 mN/m (C20 and pC20), the effectiveness (πCMC), the maximum surface excess (Γmax), and the minimum surface area (Amin) were measured at 20, 40, and 50°C. The molecular architecture of the spacers in these compounds strongly influences the thermodynamic parameters, such as the standard change for Gibbs free energy of adsorption (ΔG°ads) and the standard change for Gibbs free energy of micellization (ΔG°mic). The ability of these surfactants to reduce surface tension is particularly good, but their distinguishing characteristic is their high relative propensity to form micellar aggregates. This aggregation ability improves as the hydrophilicity and flexibility of the spacer increase. Finally, in less than 30 days, all non-ionic Gemini surfactants were determined to be 99% biodegradable in river water.","PeriodicalId":17083,"journal":{"name":"Journal of Surfactants and Detergents","volume":"28 3","pages":"535-556"},"PeriodicalIF":1.6,"publicationDate":"2024-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143939050","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Biosurfactant rhamnolipids are not prone to induce antimicrobial resistance due to their potential to target microbial membranes in both bacteria and fungi.

This study applied previously synthesized anionic fluorescent Trisodium 8-hydroxypyrene-1,3,6-trisulfonate (HPTS)-based surfactants, with hydrophobic tails from C8 to C18, to examine their interaction with the plant pathogen Alternaria alternata. The antifungal potency of the surfactants exhibited a positive correlation with the increase in hydrophobic chain length, culminating in C16, which demonstrated the highest activity. Subsequently, a modest reduction in potency was noted for the C18. Fluorescence microscopy confirmed the membrane targeting of HPTS-C16, and molecular dynamics simulations supported its specific membrane interaction. HPTS-C16 was notably more effective against spores than mycelium, consistent with its binding affinity. This research provides a fluorescent method to dissect the relationship between surfactant properties and microbial membrane characteristics, guiding the development of antimicrobials to combat resistance.","PeriodicalId":17083,"journal":{"name":"Journal of Surfactants and Detergents","volume":"28 3","pages":"511-522"},"PeriodicalIF":1.6,"publicationDate":"2024-11-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143939646","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although N-lauroyl-l-glutamate is reported in the literature, the effect of the two carboxylate groups in it has not been specifically addressed. In this study, we report the interactions of bovine serum albumin (BSA) with N-lauroylglutamate (S1) and an N-lauroyl derivative of a tripeptide of glutamic acid (S2), respectively. The surfactant S1 has two and S2 has four carboxylic acid groups making them different from other N-lauroyl amino acids, which have just one carboxylic acid group. The aim of this study is to understand the role of the number of carboxylate groups present in these amino acid-based anionic surfactants while interacting with biomolecules such as BSA. The critical micelle concentration (CMC) of the surfactants were measured both in the presence and absence of BSA using fluorescence spectroscopy. The fluorescence of BSA was quenched on addition of the surfactants. The mechanisms of fluorescence quenching were established by studying the fluorescence at three different temperatures. CD studies were performed to calculate the temperature at which BSA unfolds completely in the presence and absence of the surfactants. Conformational changes in the secondary structure of BSA were also observed on the addition of S1 and S2. The results of these studies are compared with those previously reported for the interactions between BSA and N-lauroylglycinate. We find that S1 has a lower CMC than S2 and lauroylglycinate. The surfactant S1 stabilized the secondary structure of BSA better at higher temperatures.","PeriodicalId":17083,"journal":{"name":"Journal of Surfactants and Detergents","volume":"28 3","pages":"501-510"},"PeriodicalIF":1.6,"publicationDate":"2024-11-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143939254","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, no direct evidences are available so far to show how emulsions are generated in porous media, and how emulsification is essential for cEOR. To address these issues, binary mixtures of several currently-used sulfonate surfactants, SH5, SH6, and SHZ, were formulated with connate brine to displace crude oil in both 2D microfluidic chips and 3D glass beads porous media, as well as artificial cores. It was found that both “oil-in-water” (O/W) and “water-in-oil” (W/O) macroemulsions can be formed in-situ inside the porous media, and they improve oil recovery mainly through breaking residual oil into small drops and improving mobility ratio, which can significantly reduce the residual oil saturation by up to 12.8% in 2D microchips. The in-situ emulsification in 3D glass beads medium can get oil recovery factor up to 15% over water flooding. In-situ formulation of microemulsion was also observed in microfluidic flow tests. Part of the oil phase is emulsified into microemulsions that are present in the middle phase, further mobilizing the oil trapped downstream, lowering residual oil saturation from 54.8% to 11.3% in 2D microchips, and enhancing oil recovery factor up to 25% in core flooding test. These findings advance insightful understanding of in-situ emulsification during surfactant flooding process under simulated oil reservoir condition, offering real-time evidence of how both macro- and micro-emulsions formation help for cEOR.","PeriodicalId":17083,"journal":{"name":"Journal of Surfactants and Detergents","volume":"28 3","pages":"479-490"},"PeriodicalIF":1.6,"publicationDate":"2024-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143939632","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Biosurfactants were confirmed by thin layer and high-performance liquid chromatography, Fourier transform infrared spectroscopy, proton nuclear magnetic resonance, and their performance was evaluated by zone inhibition and critical micelle concentration (CMC). The saponin and rhamnolipid reduced the surface tension (ST) of water from 72 to 40 and 30 mN/m at their CMCs, respectively. Four novel shampoo formulations were made with SLS, rhamnolipid, saponin, and a mixture of rhamnolipid and saponin. The green shampoos were evaluated with tests of color, odor, transparency, pH, ST, detergency, solid content, foam type, foam volume, wetting time and microbial contamination standard to determine the physicochemical properties. The green formulations with rhamnolipid, saponin and mixture of rhamnolipid and saponin were clear and transparent with a good odor.

We have attempted to address the aforementioned implications in this article by synthesizing a novel class of structuring agents 2-alkyl amino pyrimidine-4-carboxylic acid amphiphiles named 2-decylamino-pyrimidine-4-carboxylic acid (DPCA), 2-dodecylamino- pyrimidine-4-carboxylic acid (DDPCA) and 2-tetradecylamino-pyrimidine-4-carboxylic acid (TDPCA), using simple procedure. To our delight, the prepared amphiphiles self-assemble to a gel matrix in various vegetable oils and mineral oils. Microscopic analyses were used to investigate the nanostructured morphology of molecular gels. Rheological studies revealed that oleogels are mechanically processable and viscoelastic. Temperature dependent and concentration dependent proton nuclear magnetic resonance (1H-NMR) studies were performed to analyze the hydrogen bonding and π–π interactions. The study discovered that gelators act as reusable phase selective gelators (PSG) of oil in water–oil mixture.
