History

The international scientific journal Tenside Surfactants Detergents was founded in 1964 and titled Tenside at this time. The reason for the foundation of Tenside was the lively public interest in environmental problems caused by detergents and cleaning agents, which was being discussed in the media and at conferences at the time.

In particular, the main subject areas were related to the environmental problems associated with the application of surfactants and other ingredients in detergents and cleaning agents. Very soon other ingredients of detergents and cleaning agents, e.g. phosphates, became the subject of critical interest in addition to surfactants. The increasingly broad subject area of surface-active compounds should be reflected in the title of the journal, and therefore, the title was first changed to Tenside Detergents in 1970 and finally to Tenside Surfactants Detergents in 1986.

The language of publication was originally German. With the increasing number of English-language contributions, this was changed, and by the end of the 1990s all contributions were published in English.

Today, Tenside Surfactants Detergents deals with all aspects of the chemistry, physics and application technology of surface-active compounds.

Review on sophorolipids – a promising microbial bio-surfactant

Chandu S. Madankar, Priti K. Borde

Page range: 95-105

Abstract

Surfactants are amphiphilic molecules used primarily for cleaning. Petroleum-based surfactants have a high production rate, but are non-biodegradable and destructive to the environment. Environmentally friendly biosurfactants are therefore becoming increasingly important. In addition to not being toxic; they are environmentally safe and mild to the skin. Depending on their structure, there are different types of biosurfactants. One of the types are the glycolipids, they are low molecular weight biosurfactants, and consist of sophorolipids. Sophorolipids are getting more attention as alternative to petroleum-based surfactants due to excellent stability at various pH levels, temperatures, and salinities. In addition to being anti-microbial, they have excellent wetting and foaming abilities and act as emulsifiers. There are numerous applications of sophorolipids in food, agriculture, biomedicine, cosmetics and personal care.

Abstract

Automatic dishwashing has been optimised in manifold ways during the last decades: new dishwashing devices (e.g. optimised for best class in energy labelling) and innovative dishwashing detergents (e.g. with advanced enzyme technologies). 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.

Effect of chemical additives on oil shale natural floatability

Ayman A. El-Midany, Nesreen Khairy, Salah E. El-Mofty

Page range: 117-123

Abstract

Improving the organic content in oil shale before retorting is a substantial target. The flotation process is proven as a good separation process for hydrophobic particles from their associated impurities. In this study, the natural floatability and the flotation with different types of reagents were investigated to show how effective these reagents are in improving their organic content (kerogen). Frothers such as pine oil and kerosene and collectors such as oleic oil and amine acetate were tested. The results indicated that the addition of any used reagent negatively affects the oil shale floatability. The descending order of flotation using chemical reagents, in terms of combustible grade and recovery, is natural floatability, with frothers, then with collectors. The grade and recovery of the naturally floated fraction are 18% and 92.7%, respectively, from 8.75% in the feed sample. The low dosage from either oleic acid or pine oil effectively reduced the grade and recovery to about 15% and 86%, respectively. Chemical reagents stand as barriers to particle–bubble attachment. The presence of higher dosages of frother leads to the agglomeration of the smaller organic particles, which leads to lower grades and recovery. While collectors play a significant role in increasing the flotation of inorganic particles rather than the organics.

Salika Santosh Mapari, Cleona Elizabeth Mary DCruz, Lalit Kumar, Prashant Jivaji Bhide, Rupesh Kalidas Shirodkar

Page range: 124-139

Abstract

The present study aimed to enhance the transdermal delivery of lacidipine by niosomal vesicles. Lacidipine niosomes were generated using the ultrasonic method, and Span 60 was used as a nonionic surfactant. Formulations were prepared containing Span 60 and cholesterol in 1:1 and 2:1 ratios, respectively, with essential oils added at increasing concentrations. 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.

Novel cationic surfactants: synthesis, surface, antimicrobial studies and applicability as an extracting agent for interested element from monazite mineral concentrate

Fatma H. Abdel-Salam, Walid M. Abdellah, Fatma A. Taher, Enass M. El-Sheikh, Mohamed A. Hassanin, Doaa M. E. Elamary

Page range: 140-159

Abstract

Two novel cationic surfactants based on palmitic acid were prepared to extract uranium from its fluids. The chemical structures of the surfactants prepared were confirmed spectroscopically. The surface activity of these surfactants was evaluated by measuring their surface tension. The cationic surfactants prepared were also tested for their biological activity against Gram-positive and Gram-negative bacteria and fungi. 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. H 2 SO 4 , an A:O ratio of 1:1 and a contact time of 15 min, an uranium stripping efficiency of 83% was obtained for the case study. After the complete stripping process, the marketable uranium concentrate was percipitated using hydrogen peroxide as UO 4 H 2 O with an uranium content of approximately 76%, which was chemically determined and confirmed by EDAX analysis.

Influence of series of long-chain cationic surfactants on the quality characteristics of nano silica induced zinc phosphated mild steel

Ruby Thomas, Manickam Janarthanam Umapathy, Giridharan Ravi

Page range: 160-169

Abstract

Mild steel panels were zinc phosphated employing environmentally safe nano silica as an accelerator and a series of four cationic surfactants as additives. The four cationic surfactants chosen were decyltriethyl ammonium bromide (C 10 TEAB), dodecyltriethyl ammonium bromide (C 12 TEAB), hexadecyltriethyl ammonium bromide (C 16 TEAB), and octadecyltriethyl ammonium bromide (C 18 TEAB). The length of the alkyl chain of the surfactant compounds influenced the quality of the coatings. The corrosion resistance of the coated panels was assessed using a salt spray test. The hydrophobicity of the coatings increased as the hydrocarbon chain length of the surfactants extended from C 10 to C 18 . Porosity, adhesion, and roughness tests were used to examine the surface properties of the coated panels. The coating weight and thickness of the resultant coatings on the base metal were used to quantify coating quality. The results of the tests revealed that the presence of C 16 TEAB additive outperformed all other components in terms of coating efficiency, coating thickness, and corrosion inhibition performance. The optimal quantity of C 18 TEAB deposited had a maximum coating weight of 0.0430 g/mm 2 that enhanced durability, appearance, and barrier qualities.

Synthesis and physicochemical properties of sodium oleyl sulfate

Xiaodan Ren, Ping Li, Xiaoyi Yang, Chaohua Guo, Jianbo Li

Page range: 170-181

Abstract

In this paper, sodium oleyl sulphate (SOS) was successfully synthesised by reacting octyl alcohol (OA) with gaseous sulphur trioxide (SO 3 ) as a sulphating reagent in a falling film reactor. The structure was determined by Fourier transform infrared (FTIR) and proton nuclear magnetic resonance ( 1 HNMR) spectroscopy. The dynamic adsorption and aggregation behaviour of SOS was systematically investigated to reveal the relationship between the structure and properties of SOS. The physicochemical properties of SOS were determined by measuring the equilibrium surface tension, dynamic surface tension and dynamic contact angle, respectively. A laser particle size analyser and a transmission electron microscope (TEM) were used to analyse the aggregation behaviour of SOS. Compared to sodium dodecyl sulphate (SDS) and sodium n -octadecyl sulphate (C 18 H 37 OSO 3 Na), which have a similar structure to SOS, the increase in hydrophobic chain size and tighter molecular packing enabled by the polar head conformation caused a decrease in CMC and an increase in surface activity. The efficiency of the surface activity was controlled by a mixed diffusion kinetic adsorption mechanism. Moreover, SOS in aqueous solution showed efficient wettability on the surface of the low-energy paraffin film at concentration above the CMC. In addition, SOS molecules can spontaneously form spheroidal aggregates with increasing concentration, and the size of the aggregates increased with the concentration.

Preparation and the foaming activity of hydroxymethyl octadecyltrimethyl ammonium chloride

Shiyi Lv, Qiaona Liu, Sanbao Dong, Jinling Li, Jie Zhang, Manxue Wang, Gang Chen

Page range: 182-189

Abstract

In this work, hydroxymethyl octadecyltrimethyl ammonium chloride (HM-OTAC) was obtained from the reaction between octadecyltrimethyl ammonium chloride (OTAC) and formaldehyde in different molar ratios. The effects of the reaction conditions (different molar ratios) on the properties of the product (surface tension, foaming, high temperature resistance, methanol resistance and salt resistance) were investigated. The results showed that the HM-OTAC produced under different molar ratios could lower the surface tension of water solutions more than the surfactant OTAC. The HM-OTAC (1:2) reduced the surface tension to 28.29 mN m −1 . The HM-OTAC produced under other molar ratios gave higher interfacial tensions than HM-OTAC (1:2). With increasing surfactant concentration, the foam volume first increased and then gradually decreased. At a concentration of 0.3 wt.%, the highest foam volume (460 mL) was produced with HM-OTAC (1:3). Compared to OTAC, the foams produced by each HM-OTAC surfactant exhibited higher temperature stability. In the presence of 30 mL methanol, the initial foam volume of all HM-OTAC surfactants (0.3 wt.%) was generally higher than that of OTAC. With 300 mL HM-OTAC (1:4) solution, the highest foam volume of 20.2 mL could be produced. HM-OTAC (1:3) showed the highest salt resistance.
