Staphylococcus aureus HA25, growing at a pH range of 5.0–8.5, was isolated from Erzurum gogermis cheese and purified using a three-phase partitioning technique. Optimal immobilization processing conditions were determined for 0.1% wt/wt chitosan, alginate, and chitosan/alginate concentrations of pure lipase enzyme. Morphological features of the immobilized enzyme structure were determined using scanning electron microscopy (SEM) analysis, and structural characterizations were determined using x-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy, and thermogravimetric (TG) analysis. The results showed that the natural structure of the lipase was largely restored upon reconstitution of the spray-dried immobilized lipase structures in water. While the free enzyme removed 52.6% of the oil added to the cotton fabric, the immobilized lipase@alginate enzyme removed ~98% of the oil added to the cotton fabric at the highest rate when used as a detergent additive. It was found that the reusability activity of chitosan@lipase, alginate@lipase, and chitosan/alginate@lipase enzymes remained at 86.4%, 92.8%, and 88.6% of their original activity, respectively. The study suggests that immobilized variations of the lipase enzyme within chitosan, alginate, and chitosan/alginate matrices may serve as a natural, secure, and efficient substitute for conventional chemical detergents, offering a non-toxic alternative for additive materials.","PeriodicalId":17083,"journal":{"name":"Journal of Surfactants and Detergents","volume":"28 1","pages":"107-121"},"PeriodicalIF":1.6,"publicationDate":"2024-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141509923","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}

In this study, we systematically evaluated the effects of eight hydrotropes on the antibacterial activity of fatty acids solubilized in a micellar system. The antibacterial activity was evaluated using minimum inhibitory concentration (MIC) as an indicator, and CMC was calculated for interfacial properties based on the measurement of the surface tension and the solubilization behavior of the oil-soluble dye. The solubilization of lauric acid (12:0 FA) in the micelles of nonionic surfactants increased and decreased the antibacterial activities of the surfactants against Staphylococcus aureus (S. aureus) and Staphylococcus epidermidis, respectively. The addition of the hydrotropes decreased the antibacterial activity of the surfactants against both Staphylococci. However, on introducing small amounts of 12:0 FA, the surfactants exhibited selective antibacterial activity against S. aureus. These antibacterial phenomena were observed at concentrations above the critical micelle concentration of the surfactants. These findings suggest that the addition of hydrotropes affects the interfacial properties and antibacterial activity of micellar systems containing antibacterial ingredients.","PeriodicalId":17083,"journal":{"name":"Journal of Surfactants and Detergents","volume":"28 1","pages":"97-105"},"PeriodicalIF":1.6,"publicationDate":"2024-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141509920","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 surface and application properties of APGSHS were studied in detail. The results showed that APGSHS showed much enhanced solubility and there for better foaming and detergency properties than APG due to the introduction of sulfonate group. Then, the mildness of APGSHS and commercially available mild surfactants was compared using zein test and hemolysis of red blood cells (RBC) test. APGSHS has higher mildness than other surfactants, such as potassium lauroylglycinate (PLG), lauramidopropyl betaine (LAB), and sodium laurylmethyl taurate (LMT). The mechanism of mildness was investigated by studying the interaction between APGSHS and protein using zein model through micelle behavior and protein structure. It was observed that compared to other anionic surfactants such as sodium fatty alcohol polyoxyethylene ether sulfate (AES) and sodium dodecyl sulfate (SDS), APGSHS possesses a larger hydrophilic head group and causes less damage to the secondary structure of zein. Finally, the effect of different surfactants on the hair keratin loss during washing was evaluated. The results showed APGSHS had a minimal damaging effect on keratin in the hair, resulting in the lowest protein loss. This work suggests APGSHS as a promising ingredient for green and mild cleaning products.","PeriodicalId":17083,"journal":{"name":"Journal of Surfactants and Detergents","volume":"28 1","pages":"85-96"},"PeriodicalIF":1.6,"publicationDate":"2024-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141509924","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}

Towards this vision, bio-based surfactants and biosurfactants are being explored as alternatives to traditional petrochemical surfactants. However, the transition towards these technologies is expected to be gradual, therefore there is a critical need to formulate new biosurfactants in combination with traditional surfactant classes such as alkoxylates, sulfates and amine-oxides to achieve a balance of performance, cost, and sustainability. To this end, we report a study of the impact of sophorolipid biosurfactants on the cloud point of alcohol ethoxylates, and on the surface tension and foaming of alkyl sulfate/amine-oxide mixtures. We make the surprising finding that high-acid sophorolipids can act as highly efficient hydrotropes and increase the cloud point of alcohol ethoxylates. In sulfate/amine-oxide mixtures, models of experimental data suggest that both high-acid and high-lactone sophorolipids can replace 40–50% of the primary surfactants without significant changes to the surface tension or foaming performance. These findings will enable the next-generation of high performing sustainable cleaning formulations to be realized.","PeriodicalId":17083,"journal":{"name":"Journal of Surfactants and Detergents","volume":"27 5","pages":"769-780"},"PeriodicalIF":1.6,"publicationDate":"2024-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141342887","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}

Many research studies have focused on the use of recycled WFO. These studies are highly promoted because of the need to find new ways of reducing the negative impact of WFO on the environment. One of these studies focused on the production of sophorolipid (SL), a naturally derived eco-friendly glycolipid biosurfactant. Unfortunately, the environmental and societal advantages brought about by the wide-spread use of SL are offset by its high production cost. WFO is a high-volume, inexpensive material that can be used as a substrate for SL production. As such, by utilizing WFO as a feedstock material cost reduction can be realized to improve large-scale application potential. One drawback to the use of WFO is that its physical characteristics are different from fresh oil and its effect on SL productivity (g/day) has not been investigated. This research focused on the effect of acid value (AV), peroxide value (PV), and carbonyl value (CV) of WFO on SL productivity. It was confirmed that SL titers (111.1 vs. 106.7 g/L) did not differ significantly after using either fresh oil (CV <0.01) or WFO, respectively. In addition, this research also confirmed that higher WFO degradation required longer culture periods (from 6 days to 9 days) to reach comparable SL concentrations as that produced with fresh oil.","PeriodicalId":17083,"journal":{"name":"Journal of Surfactants and Detergents","volume":"27 5","pages":"703-710"},"PeriodicalIF":1.6,"publicationDate":"2024-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141355401","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}

This work presents an efficient process to remove HC pollution from seawater: cloud point extraction (CPE), considered to be a reliable, inexpensive, and environmentally friendly method, using the readily biodegradable nonionic surfactants Lutensol ON30 and Tergitol 15-S-7. A real salt water sample with a high chemical oxygen demand (COD = 1700 mg O2/L) was thus treated. First, the phase diagrams of the binary systems (water–surfactant), and the pseudo-binary systems (water–surfactant–HC), were determined. Second, after a 24 h settling time, considered as optimal, the extraction results, that is, residual soluble COD, residual percentage of surfactant in the dilute phase and volume fraction of coacervate at equilibrium, were expressed in terms of temperature and initial surfactant concentration. For each parameter, the results obtained were modeled using the response surface methodology and represented on three-dimensional diagrams. They show that the COD can be reduced to 10 and 15 mg O2/L, using Lutensol ON30 and Tergitol 15-S-7, respectively, under seawater temperature conditions. Finally, it was shown that the surfactant can be recycled.

Novel nonionic surfactants such as PEMP, BEMP, HEMP and BEEP were synthesized based on succinic acid derivatives and using L-isoleucine as the linking group and four polyether alcohols as the hydrophilic group. First, the structures of the four nonionic surfactants were studied using Fourier transform infrared (FTIR) spectroscopy and nuclear magnetic resonance (NMR) spectra. Then the critical micelle concentration (CMC) and surface tension at CMC (γCMC) of the four nonionic surfactants in aqueous solution were tested. γ-lg c curves determined the relationships of their surface properties as BEEP > PEMP > BEMP > HEMP. In order to expand the range of applications for nonionic surfactants, we evaluated the salt-resistant properties of four such surfactants. Our findings demonstrated that this class of surfactants indeed has superior salt-resistant properties. Molecular dynamics (MD) simulations were used to study how surfactant molecules aggregate in the interfacial film. The study investigated the trend of solvent accessible surface area (SASA) over time. Results showed that the surfactant molecules interacted well with solvent molecules in the equilibrium state.

However, limited surfactants were able to effectively adsorb at the supercritical CO2–water (C–W) interface considering the weak solvent strength of CO2, especially at high temperatures. Herein, attempts have been made to design suitable CO2 foaming agents by evaluating the influence of proportions of anionic and cationic surfactants and the affinity between aminopropyl methyl siloxane (APSi) and CO2. Through systematical foamability and foam stability experiments, together with the measurements of C–W equilibrium and dynamic interfacial tensions, the adsorption and stabilization mechanisms of sodium alpha olefin sulfonate (AOS)-APSi aqueous dispersions on the CO2 foam films are revealed. Excellent foam properties were observed at AOS/APSi mass ratio of 9:1, in which initial foam height (h0) and half-life period (t1/2) first increased and then decreased with increasing pressure, whereas the interfacial tension decreased with increasing pressure. The results indicate that the interaction of anionic and cationic head-groups contributes to accelerating the surfactant adsorption rate from bulk to the C–W interface, enhancing foamability and stabilizing foam. Besides, the AOS/APSi mass ratio of 8:2 shows a good affinity for CO2 at 15 MPa, of which h0 is 26% higher and t1/2 is 60% slower than AOS alone. Furthermore, the initial mean bubble area of both 9:1 and 8:2 AOS/APSi mixtures was around half that of AOS alone. This work broadens the design of novel surfactant methodologies including CO2 foam, providing a theoretical guidance for the application of CO2 on enhanced-oil-recovery technologies.","PeriodicalId":17083,"journal":{"name":"Journal of Surfactants and Detergents","volume":"27 4","pages":"589-603"},"PeriodicalIF":1.6,"publicationDate":"2024-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141189152","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}
