Alkyl Ethoxylated and Alkylphenol Ethoxylated Nonionic Surfactants: Interaction with Bioactive Compounds and Biological Effects
Nonionic surfactants are amphipathic molecules consisting of a hydrophobic (alkylated phenol derivatives, fatty acids, longchain linear alcohols, etc.) and a hydrophilic part (generally ethylene oxide chains of various length). Although not as important commercially, tertiary amine and various sugar surfactants are also nonionic surfactants. Due to their favorable physicochemical properties, no...
متن کاملNovel Ethoxylated Inositol Derivatives - Chemical Mixtures of Sugar- and Oligo(ethylene oxide)-based Surfactants
Sugarand oligo(ethylene oxide)-based surfactants behave quite differently despite of both being non-ionic surfactants. In a large number of studies the properties and behaviour of these two different kinds of surfactants were addressed. However, it was only recently that an extensive investigation has been carried out on the properties of respective mixtures focussing on mixtures of β-C12G2 (n-...
متن کاملALKYL IMIDAZOLINES AND THEIR ETHOXYLATED DERIVATIVES AS ANTIOXIDANTS FOR HYDROCARBON PRODUCTS
Alkyl imidazolines have been reportedly used in a wide range of industrial formulations with different applications. Ethoxylated alkyl imidazolines with appropriate ethoxylation degrees can be used as antioxidants and retarders in the formation of peroxides resulting from oxidation in hydrocarbon media. In this work, ethoxylated imidazolines were shown to be more effective in hydrocarbon media ...
متن کاملAdsorption of mixtures of nonionic sugar-based surfactants with other surfactants at solid/liquid interfaces II. Adsorption of n-dodecyl-β-D-maltoside with a cationic surfactant and a nonionic ethoxylated surfactant on solids
Synergy and antagonism between sugar-based surfactants, a group of environmentally benign surfactants, and cationic surfactants and nonionic ethoxylated surfactants have been investigated in this study with solids which adsorbs only one or other when presented alone. Sugar-based n-dodecyl-β-D-maltoside (DM) does not adsorb on silica by itself. However, in mixtures with cationic dodecyltrimethyl...
متن کاملAnalysis of hydraulic fracturing flowback and produced waters using accurate mass: identification of ethoxylated surfactants.
Two series of ethylene oxide (EO) surfactants, polyethylene glycols (PEGs from EO3 to EO33) and linear alkyl ethoxylates (LAEs C-9 to C-15 with EO3-EO28), were identified in hydraulic fracturing flowback and produced water using a new application of the Kendrick mass defect and liquid chromatography/quadrupole-time-of-flight mass spectrometry. The Kendrick mass defect differentiates the proton,...
