Imidazolium-based SAILs have unique physicochemical properties and greater surface activity than conventional surfactants, which allows them to increase drug permeability, making them better drug carriers than currently available formulations. To fully utilize [C14bim][Br] and [C10bim][Br] in drug delivery applications, deep insight into the interactions occurring in the mixed micellar [C10bim][Br]/[C14bim][Br] systems in the drug’s presence are necessary to be examined. Thus, the study is conducted using conductivity and surface tension measurement techniques to fully exploit the self-assembly, micellization behavior and interactions occurring in the pure and mixed micellar system of [C10bim][Br]/[C14bim][Br] in water and 5 mM of SS solution in aqueous media. For this, various thermodynamic, surface-active and mixed micellar parameters of micellization have been calculated and analyzed with respect to change in mole fraction, temperature and addition of SS in solution.","PeriodicalId":22258,"journal":{"name":"Tenside Surfactants Detergents","volume":"60 1","pages":"338 - 355"},"PeriodicalIF":1.0,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46956571","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 study focused on determining the critical micelle concentration (CMC) of the three pure SAILs and their mixtures with NaCMC to evaluate various thermodynamic and interfacial parameters. The results showed that the CMC values decreased significantly with increasing hydrophobicity of the SAILs, while the CMC increased with a gradual increase in the NaCMC mole fraction in the SAIL–NaCMC mixed systems. It was observed that the excess free energy of micellization ( ∆ G e x m ${{increment}G}_{ex}^{m}$ ) and the minimum free energy of surface at equilibrium ( ∆ G min s ${{increment}G}_{mathrm{min}}^{s}$ ) exhibited an opposite behaviour, indicating that the formed mixed micelles were stable while the formed surface was unstable.

Most synthesized IL surfactants are not environmentally benign, and even utilizing high concentration, they form unstable micelles. In this regard, we have synthesized biocompatible and halogen free choline based ionic liquids by varying anions (choline oleate and cholinium bis(2-ethylhexyl) sulfosuccinate) and further investigated their micellization behavior in presence of the drug Cetrizine dihydrochloride. Characterizations of these synthesized ionic liquids were performed utilizing 1HNMR spectroscopy. The thermodynamic investigation and determination of various surface-active parameters were based on tensiometry and conductometric titrations. The CMC value of choline oleate ([CHO][Ole]) was found to be lower than that of [Cho][AOT] and thus it has a better surface activity. The thermodynamic parameters (ΔGm0${{Delta}G}_{m}^{0}$, ΔHm0${{Delta}H}_{m}^{0}$, and ΔSm0${{Delta}S}_{m}^{0}$) signifies spontaneous, stable, exothermic and entropy driven nature of micellization process.

MES is often produced via sulfonation of methyl ester (ME) with sulfonating agent. In this study, ME was synthesized from used cooking oil (UCO) via transesterification and then sulfonated to produce MES using two different sulfonating agents (chlorosulfonic acid (CSA) and sodium bisulfite (NaHSO3)). The influence of various factors (temperature, sulfonating agent/ME molar ratio and time) on MES yield was investigated. Analysis of optimal MES samples was carried out using different techniques (GC-FID, FTIR and 1H NMR). The maximum MES yield of 88.2 % was achieved with CSA/ME molar ratio of 1.2:1 at 70 °C for 3 h while the highest MES yield of 79.4 % was obtained with NaHSO3/ME molar ratio of 1.2:1 at 90 °C for 3 h. FTIR and 1H NMR analyses revealed the presence of methyl (CH2− asymmetric and CH2− symmetric stretching vibrations), esters (C=O, C–O, and O–CH3), and sulfonate (S=O) groups in MESCSA and MESNaHSO3 samples, thereby affirming the desired product. Surface tension analysis showed that the MESCSA and MESNaHSO3 have low critical micelle concentrations of 0.079 g/L and 0.14 g/L, respectively while the corresponding surface tensions were 51.9 mN/m and 30.94 mN/m for MESCSA and MESNaHSO3 respectively.","PeriodicalId":22258,"journal":{"name":"Tenside Surfactants Detergents","volume":"60 1","pages":"277 - 285"},"PeriodicalIF":1.0,"publicationDate":"2023-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41905109","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 present study focuses on the synthesis of sulfonyl chloride derivatives as nonionic surfactants (surfactant 1 and surfactant 2) and their evaluation for the preparation of a clarithromycin-loaded niosomal drug delivery system. Surfactants 1 and 2 were characterised by EI-MS and 1H NMR spectroscopy. The shape and size of the drug-loaded niosomal vesicles from the synthesised surfactants were examined by atomic force microscopy (AFM) and revealed a round morphology with an average size of (230.8 ± 2.35) nm and (248.1 ± 2.54) nm for the vesicles of surfactant 1 and surfactant 2, respectively. The zeta potential of surfactant 1-based niosomal vesicles was (– 7.70 ± 1.00) mV and that of surfactant 2 was (−14.6 ± 1.08) mV. The lower zeta potential values for surfactant 1 and surfactant 2-based niosomal vesicles showed that these vesicles were neutral and relatively stable. The vesicles of surfactant 1 and 2 have a capacity to entrap the drug of about (62 ± 2.26) % and (69.67 ± 3.23) %, respectively. The vesicles of surfactant 1 released the largest amount of drug, i.e. (70.00 ± 2.45) % at pH 1.2. Biocompatibility in human blood and toxic effects on various cell lines were also studied for surfactants 1 and 2, and they were found to be biocompatible and non-cytotoxic.","PeriodicalId":22258,"journal":{"name":"Tenside Surfactants Detergents","volume":"60 1","pages":"328 - 337"},"PeriodicalIF":1.0,"publicationDate":"2023-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42584624","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}

Using the pseudo-first-order condition, the course of the reaction was studied as a function of [Fe(CN)63−], ionic strength, [OH−], [SDS], [Ru3+], [L-PheAla] and temperature by changing one variable at a time. The results exhibit that [OH−], [SDS], and [L-PheAla] are the crucial parameters that have an appreciable influence on the reaction rate. The reaction exhibits first-order kinetics in concentration ranges of Ru(III), [Fe(CN)6]3− and at low [L-PheAla] and [OH−] concentrations. The incremental trend observed in the reaction rate with electrolyte concentration shows a positive salt effect. The reaction rate is almost 10 times faster in SDS micellar medium than in aqueous medium. [Fe(CN)6]3− has no appreciable effect on the CMC of SDS, since the polar head of SDS and [Fe(CN)6]3− are both negatively charged. The K+ obtained from K3[Fe(CN)6] and KNO3 decreases the repulsion between the negatively charged heads of the surfactant molecules, which decreases the CMC of SDS. The activation parameters also support the outer-sphere electron transfer mechanism.","PeriodicalId":22258,"journal":{"name":"Tenside Surfactants Detergents","volume":"60 1","pages":"376 - 386"},"PeriodicalIF":1.0,"publicationDate":"2023-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43820630","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}

Felodipine undergoes extensive hepatic first pass metabolism resulting in low oral bioavailability of 15 %. The aim of this study is to develop a formulation of nanovesicular Spanlastics to improve the transdermal delivery of felodipine and solve the problem of low bioavailability. The felodipine-loaded Spanlastics were prepared using the ethanol injection method with Span 60 as surfactant and Tween 80, which provides elasticity to the vesicles, according to the 23 factorial design using Design Expert® Software version 13. The solution that had the highest desirability was optimized. The final five runs were incorporated into a gel base and evaluated for in vitro drug release, spreadability and viscosity. Stability studies were conducted over a period of 3 months. The formulated Spanlastics had a particle size in the range of (132–155) nm and an entrapment efficiency in the range of (80–94) %. The final five runs were found to have optimum characteristics. Differential scanning calorimetry, X-ray diffraction studies and Fourier transform infrared studies were performed to ensure the encapsulation of the drug in the nanovesicles. The developed hydrogel showed in vitro drug release in the range of (80–94) % and the formulation was found to be stable after a period of 3 months. The optimized formula comprised of Span 60 and Tween 80 in ratio of 8:2.
