In this study, binary mixtures of sodium lauryl sulfoacetate (SLSA) and an alkyl polyglucoside (APG10) in various proportions were investigated for their effectiveness as degreasing agents. Efficacy was characterised using surface tension measurements, oil dispersion tests, emulsification, pH and cleaning efficacy in removing engine oil from a metal plate. The surface tension results for all solutions showed a critical micelle concentration of 1500 ppm. The dispersion tests (with oil:surfactant ratios of 1:2 and 1:3) showed that the oil was fully dispersed at an oil:surfactant ratio of 1:2 i.e., at a concentration of 2500 ppm SLSA and 2000 ppm of a binary solution with a volume ratio of SLSA:APG10 of 75:25. At a ratio of 1:3, the oil was fully dispersed with 2500 ppm of a binary solution with a ratio of SLSA:APG10 of 75:25. Overall, the solution with a volume ratio of SLSA:APG10 of 75:25 was the most favourable. The results also showed that a solution containing only SLSA had good potential as a degreaser, as it achieved a cleaning performance of 90% in removing oil from the metal plate despite low emulsification levels (E24) for both surfactants. In summary, a combination of these two green surfactants can be used effectively as a degreasing agent.","PeriodicalId":22258,"journal":{"name":"Tenside Surfactants Detergents","volume":null,"pages":null},"PeriodicalIF":1.0,"publicationDate":"2023-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43750728","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}

CAPB and SDBS were not found to interact synergistically in water at any of the molar fractions studied. This is due to the fact that the critical micelle concentrations of these mixtures were higher than those predicted by Clint’s equation, indicating an antagonism that rarely occurs in mixed amphoteric/anionic surfactant systems. The minimum area occupied by a surfactant molecule (Amin) was reduced in CAPB/SDBS mixtures compared to unmixed surfactants. In contrast, the viscosity of the mixed CAPB/SDBS system increased significantly from 1.0 mPa s to a maximum of 36.0 Pa s at higher CAPB mole fractions (0.5–0.8). The rheograms obtained from the oscillation measurements of the viscous CAPB/SDBS solutions are characteristic of wormlike micelles (WLMs) according to the Maxwell model.

Such synergism is confirmed by surface tension values, critical micelle concentration (CMC), and interaction parameter values according to Holland and Rubingh’s model and the satisfaction of Hua and Rosen conditions. Surface excess (Γ) at air/water interface and the minimum area occupied by surfactant molecule (A min) also indicated a reduction in the A min of mixed CAPB/SDBS compared to single surfactants that is due to the strong electrostatic interaction between surfactants heads. The composition of CAPB/SDBS mixed micelles, the interaction parameter (β) and the micellar activity coefficients (f 1 and f 2) were evaluated from the regular solution model for these binary amphoteric/anionic mixed systems. It is clear the CAPB surfactants are converted to the cationic form by charging in the presence of HCl, which enhances the interaction between the oppositely charged CAPB and SDBS heads and overcomes the unfavourable packing between the tails predicted in pure water. Such strong interaction was also reflected on the phase behavior of CAPB/SDBS binary mixed system. Accordingly, a switching from antagonism to synergism is reported for CAPB/SDBS binary mixed system in the presence of dilute hydrochloric acid.","PeriodicalId":22258,"journal":{"name":"Tenside Surfactants Detergents","volume":null,"pages":null},"PeriodicalIF":1.0,"publicationDate":"2023-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43795223","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, the washing and decontamination of moisture-wicking fabrics, especially the performance and decontamination effect of moisture-wicking fabrics after washing were investigated. The results showed that the physical morphology of moisture-wicking fabric is very different from that of an ordinary polyester fabric. The cross-section of the moisture-wicking fabric is hexagonal, and this fabric has good hydrophilicity. After the degreasing & thermosetting process, the air permeability of the moisture-wicking fabric is increased from 1013 mm/s to 2911 mm/s. However, the air permeability is decreased after one washing, but it has little effect during the subsequent washing cycles. Moreover, the degreasing & thermosetting process also improve the stains removal index. If the moisture-wicking fabric was washed before the preparation of stained fabric, the stain removal index of carbon black soil and sebum stains is increased. Although most of the aggregated particles on the surface of the fibers are removed after washing, a small amount of sebum still remains in the spaces between the fibers. These results indicate that most of the carbon black in the stained area is removed after washing, while oil components are hardly removed from the moisture-wicking fabric during home laundry. Compared to other surfactants, C18 fatty acid methyl ester ethoxylates and nonionic surfactants with long carbon chains can effectively reduce the surface tension of water and improve the wettability of moisture-wicking fabric, so that water molecules can diffuse well between fibers and stains, the binding force between stains and fabric is weakened, and the decontamination of the fabric is improved.","PeriodicalId":22258,"journal":{"name":"Tenside Surfactants Detergents","volume":null,"pages":null},"PeriodicalIF":1.0,"publicationDate":"2023-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46835773","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 formulated niosomes had nano-vesicles with entrapment efficiency ranging from 75.81% to 91.25% and in-vitro drug release ranging from 80.61% to 89.81%. The optimal formulation was selected based on particle size, entrapment efficiency and in-vitro drug release. Optical microscopy and high-resolution transmission electron microscopy studies revealed a spherical shape of the niosomal vesicles. Fourier transform infrared spectroscopy, differential scanning calorimetry and X-ray diffraction studies confirmed complete encapsulation of the drug in the niosomal vesicles. The optimized formulation was also incorporated into a gel base, which was then evaluated for appearance, pH, viscosity, spreadability, in vitro drug release and stability. Overall, the results indicated that the developed niosomal lacidipine vesicles may provide an alternative to existing delivery systems for this drug.","PeriodicalId":22258,"journal":{"name":"Tenside Surfactants Detergents","volume":null,"pages":null},"PeriodicalIF":1.0,"publicationDate":"2023-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46505655","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}

Subsequently, an attempt was made to use these surfactants to remove uranium from the hydrous oxide cake produced after the alkaline degradation of monazite mineral concentrate. To achieve this goal, several experiments were conducted to determine the optimal conditions for uranium extraction and stripping. Under these optimal conditions, the experimental capacity fitted the pseudo-second order kinetic model. Under the investigated optimal stripping factors of 1 M NaCl, acidified with 0.2 M conc.

However, the usage of the automatic dishwasher in consumers’ home may not be adequate to gain all the benefits from these developments. Little is known about the actual consumer behaviour with automatic dishwashing. This was tried to solve by performing a survey on the consumer behaviour on automatic dishwashing in Germany, Italy, Spain, Poland, Hungary and Turkey covering large parts of Europe. The results show that the ‘eco’-programme is getting more importance in programme selection. However, feedback on the soil level of the dish items put into this programme and the observed duration of the programme show that the potential of the ‘eco’-programme is not fully utilised by consumers. Besides this, the survey delivers relevant details on differences which may help to understand the needs and wishes of consumers in those countries.","PeriodicalId":22258,"journal":{"name":"Tenside Surfactants Detergents","volume":null,"pages":null},"PeriodicalIF":1.0,"publicationDate":"2023-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48061819","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}
