However, there have been no attempts as yet to use the SZP technique in the presence of surfactants. In this work, we studied the effect of classical low-molecular surfactants (SDS, АОТ, Triton X-100, and CTAB) on the properties of tracer particles with different size: commercial polystyrene (PSN, 27.2 ± 0.1 nm), “blue” colloidal (BI-ZR5, 191 ± 1 nm), and hydrophilic SiO2 particles (520 ± 12 nm) obtained by quartz evaporation under the action of a relativistic electron beam. The initial charge of all the particles was negative. Anionic surfactants (АОТ and SDS) exerted virtually no effect on ζ-potential up to the concentration of 10−3 M and decreased it by ca. 27% at the concentration of 10−2 M. Nonionic oxyethylated Triton X-100 increased ζ-potential but did not recharge the particles. Cationic CTAB recharged the surface of all the particles already at the concentration of 10−5 M; at 10−2 M ζ-potential reached 39–65 mV. The possibility of applying BI-ZR5 as the tracer particles to estimate the electrokinetic potential of the borosilicate glass substrate in the presence of CTAB was demonstrated.","PeriodicalId":17083,"journal":{"name":"Journal of Surfactants and Detergents","volume":"27 3","pages":"333-340"},"PeriodicalIF":1.6,"publicationDate":"2024-01-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139482474","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}

The results show that: (1) the higher the pressure, the higher the foaming rate of the foaming agent and the more stable the foam, but the foam stability of the foamers at low and high pressures, and low and high temperatures do not correspond exactly, and the foaming agent used needs to be screened under simulated reservoir conditions. (2) The comprehensive foaming performance of different types of foamers with different molecular structures found that hydroxy sulfobetaine with longer carbon chains has a relatively better foaming performance. Therefore, for the reservoir conditions of temperature 130°C, pressure 30 MPa, and salinity 22 × 104 mg/L, hydroxy sulfobetaine, which does not contain an amide group in the molecule, can be considered preferentially as a foaming agent.

However, traditional surfactants have their limitations, particularly in terms of stability under high temperatures and salinity levels. This study delved into a groundbreaking macromolecular polymeric surfactant, S-AV, which holds the unique ability to transform rock surface characteristics, effectively stripping away residual oil while maintaining resilience against elevated temperatures and salinity. S-AV was synthesized through a free-radical copolymerization process, incorporating benzyl, perfluoroalkyl, alkyl-, benzyl-, ethylene glycol, and amide-alkyl-sulfonate groups, ultimately yielding a comb-like molecular structure. S-AV demonstrated exceptional prowess, swiftly reducing the underwater oil contact angle to 53.4° in just 48 h. This synthesized surfactant also retained its phase stability up to salinity levels of 36,000 ppm, with temperature having no disruptive impact on its phase stability performance. Furthermore, S-AV showcased remarkable viscosity reduction in conditions of high temperature and salinity. The core flooding experiments underscored the potential of S-AV, as its injection led to a significant oil recovery rate of up to 83%. These findings position S-AV as a promising candidate for practical enhanced oil recovery applications.","PeriodicalId":17083,"journal":{"name":"Journal of Surfactants and Detergents","volume":"27 3","pages":"421-432"},"PeriodicalIF":1.6,"publicationDate":"2024-01-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139376706","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}

Conventional surfactants widely used in nanoemulsion formulations namely, polysorbate 80, macrogolglycerol ricinoleate, and 4-octylphenol polyethoxylate have been associated with anaphylactoid responses, alterations in normal flora, cytotoxicity and tissue damage. The use of less toxic, environment-friendly microbial biosurfactants in the formulation of nanoemulsions have been demonstrated to manifest stability, slow drug release, enhanced skin permeability, and bioactivity. The type and composition of mixed microbial biosurfactants used in nanoemulsions can decrease the droplet size and synergistically increase the stability. Moreover, a lower concentration of drug-loaded surfactin-based nanoemulsion synergistically inhibited the proliferation of cancer cells by 50% (IC50). The scope of the current review is to focus on the prospect of substituting conventional surfactants with biosurfactants obtained from microbial origin for nanoemulsion formulations. It also aims to draw attention to the paucity of research in the combinatorial study of biosurfactants and functional drugs used in nanoemulsions. The review emphasizes the bioactivity of microbial biosurfactant-based nanoemulsions and their applications in diverse sectors. The differences in emulsion stability and size of microbial biosurfactant and conventional surfactant-based nanoemulsions have been highlighted. The study intends to promote comparative research between nanoemulsions prepared using conventional surfactants and microbial biosurfactants.","PeriodicalId":17083,"journal":{"name":"Journal of Surfactants and Detergents","volume":"27 2","pages":"163-181"},"PeriodicalIF":1.6,"publicationDate":"2023-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138717289","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, there are no reports on photosensitive micellar solutions containing trimeric cationic surfactant. In the study, novel photosensitive viscoelastic micellar solutions consisting of trimeric cationic surfactant (TEC) and trans-ortho-methoxycinnamic acid (trans-OMCA) were investigated. This study utilized rheology, UV–vis spectroscopy, and cryo-TEM to investigate the photo-responsive behavior and mechanism of the TEC/trans-OMCA micellar solutions. Rheological studies revealed that the concentration of TEC and trans-OMCA, as well as temperature, significantly affected the viscoelastic properties of the micellar solutions. Furthermore, the Carreau and Maxwell models might be used to characterize the flow curves and viscoelasticity of the micellar solutions, respectively. Notably, TEC/trans-OMCA micellar solutions exhibited excellent light-induced thinning characteristic, with the optimal performance at a mass ratio of φ = 0.5. After UV irradiation, the zero-shear viscosity of TEC/trans-OMCA (0.6/0.3 wt%) micellar solution was reduced by 352 times, while the viscoelasticity and the area of hysteresis loops were significantly reduced. This drastic change in the rheological characteristics of the micellar solutions could be attributed to the photoisomerization of trans-OMCA and the resulting changes in the internal microstructure of the solutions. Moreover, the viscosity of the micellar solutions diminished as the temperature increased, with the remaining viscosity of the TEC/trans-OMCA (1.0/0.5 wt%) micellar solution at 36.4 mPa s at 95°C. This study expands on the potential utilization of oligomeric surfactants in the construction of photorheological viscoelastic fluids.","PeriodicalId":17083,"journal":{"name":"Journal of Surfactants and Detergents","volume":"27 3","pages":"319-331"},"PeriodicalIF":1.6,"publicationDate":"2023-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138717163","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}

Two types of rock samples from sandstone reservoirs of Assam oilfields in India are selected based on XRD results. These rock types are (i) high carbonate cement (HCC) core sample with higher carbonate cement (calcite 5.6% and dolomite 4.0%), and (ii) low carbonate cement (LCC) core sample with lower carbonate cement (calcite = 0.5% and dolomite 0%). The study reveals that the mineralogy of sandstone reservoir rocks especially the carbonate minerals affects the brine-rock interactions including wettability alternation and surfactant adsorption. Notable differences (2° to 8°) in contact angles for the two rock types at different salinities revealed that carbonate cement in sandstone thus impacts brine-rock interactions. Further, low salinity surfactant (LSS) could positively alter the wettability of both rock types to water-wet conditions (contact angle <60°). The most favorable wettability alterations (up to 30°) were achieved with cationic LSS solutions for both core types. Using LSS solutions also reduced the adsorption of anionic surfactant by around 40% and 33% for HCC and LCC rock samples, respectively. The study's novelty emanates from investigating the impact of sandstone reservoir rock mineralogy with varying amounts of carbonate cements on the adsorption behavior of surfactants under low-salinity conditions. Moreover, this study provides a better understanding of the interrelationship existing between the degree of wettability alteration and the amount of surfactant adsorbed by sandstone rocks.","PeriodicalId":17083,"journal":{"name":"Journal of Surfactants and Detergents","volume":"27 3","pages":"393-408"},"PeriodicalIF":1.6,"publicationDate":"2023-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138494970","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}

The formulations based on the mole fraction were utilized for preparing mixed micelles with anionic sodium dioctyl sulfosuccinate (AOT) and sodium dodecyl sulphate (SDS). DLS measurements demonstrated the formation of small micelles and mixed micelles in SDS-AOT combinations. A UV absorbance investigation demonstrated the effectiveness of the SDS-AOT mixed micelles for determining the binding constant (Kb) and mean ion occupancy (i0) of the anticonvulsant gabapentin (GBP) drug. Kb values increased, but the occupancy (i) of GBP per micelle decreased by decreasing the mole fraction (α) of SDS from αSDS 0.9 to 0.1, predicting a shift in occupancy of drugs from the Palisade to the Stern layer. To get a better comprehension of micellization behavior and preferential interaction of the drugs under study, molecular docking studies were performed. According to the docking studies, the GBP displayed significant binding in the presence of SDS-AOT when compared to pure SDS and AOT molecules. Ultimately, in pharmaceutical applications, mixed micelle played an important role in enhancing the binding and encapsulation efficiency of drugs.","PeriodicalId":17083,"journal":{"name":"Journal of Surfactants and Detergents","volume":"27 3","pages":"433-444"},"PeriodicalIF":1.6,"publicationDate":"2023-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135679002","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}
