Among the various derivatives of alkyl polyglucoside, the anionic alkyl polyglycoside esters (AGEs) and AGE-nonionic surfactant mixtures can able to increase wettability, and it may increase mineral content in soils. The phosphate alkyl polyglucosides show good performance in detergency and better wetting properties with good biodegradability. The sulfonated alkyl polyglucosides are a good alternative to nonylphenol ethoxylate and exhibit superior cleaning of edible oil.

In environmental risk assessment, it is essential to understand the relationship between molecular structure and fate and toxicity of organic contaminants. For surfactants, physico-chemical parameters which can reflect the interactions that determine surfactant behavior are not well defined and are therefore needed for the development of robust quantitative structure-activity relationships (QSAR).

An aqueous two-phase extraction system was constituted using magnetic ionic liquid-nonionic surfactant for phenolic acids and the developed method was applied to apple, grape, pear, and banana samples. Ionic liquids based on imidazolium containing butyl, allyl, and benzyl groups were used for extraction. The parameters influencing the extraction efficiency such as volume of ionic liquids, type and amount of surfactant and salt, ultrasound extraction time, temperature, and sample pH were optimized.

In this study, nano zinc borate powder was synthesized by a wet chemical method and the effects of nonionic, anionic, and cationic surfactants on the particle size and morphology of the zinc borate particles were investigated. Chemical purity and physical structures of the synthesized zinc borate powder were analyzed by XRD, FTIR, TG-DTA, TEM, and Zetasizer. The analysis results showed that the zinc borate powder had a chemical formula of 2ZnO·3B2O3·7H2O.

In this study, the electrochemical properties of desloratadine, which is in the second generation antihistamines group, were determined by bismuth film electrode (BiFE) in aqueous and aqueous/surfactant solutions. This compound gave an irreversible and diffusion-controlled reduction peak at about –1.65 V by cyclic voltammetry. It was found that the addition of cationic surfactants (cetyltrimethylammonium bromide (CTAB) increased the reduction current signal of desloratadine, while anionic (sodium dodecylsulfate (SDS) and nonionic (Tween 80) surfactants were found to have an adverse effect.

This research work is focused on the cloud point extraction (CPE) procedure for the preconcentration of rifampicin prior to its determination in water. The UV/vis spectrophotometric method was adapted for the measurement of rifampicin content after the phase separation. Triton-X 100 was used as the nonionic surfactant which contains hydrophilic polyethylene chain feasible for the extraction of analyte. Various analytical parameters that can affect the extraction efficacy were optimized to achieve linearity of the proposed method in the concentration range of 3.54–81.41 mgL–1.

Electroporation is a safe and efficient method to transfect human tooth germ stem cells (hTGSCs), which are mainly mesenchymal stem cells (MSCs). In this study, pluronic F68 (PF68), a nonionic and low-foaming surfactant, was used for the first time to increase the transfection efficiency in electroporation of hTGSCs.

Introduction: Surfactants can be classified into cationic, anionic and nonionic ones. Benzalkonium chlorides are cationic surfectants and being widely used as a disinfectant and germicide using their strong protein-denaturing action. Especially in hospitals, 10 % solution of benzalkonium chloride mixture is being usually used; it is diluted to 0.05–0.1 % solution to be used for various types of disinfection. The drugs are contained in gargles and preservative solutions for contact lenses.
