Sédiments contaminésIndex. décimale : 668.1 Agents tensioactifs : savons, détergents Résumé : In the present paper analysis of alkylphenols and their short-chained ethoxylates was presented. The analytes were determined in sediments from Lake Malta as well as in water incoming to and outgoing from the lake. Sonication-assisted extraction was used for isolation of the analytes from the sediment samples. Solid-phase extraction with polytetrafluoroethylene sorbent was used for both clean-up of extracts and isolation of analytes from the water samples. Alkylphenols and their ethoxylates were quantitatively analysed with the use of HPLC with fluorescence detection. The analytes were determined in the sediment samples at relatively low concentrations with the maximum concentration of 168 μg kg–1 for nonylphenol monoethoxylate, which can be ascribed to periodic removal of sediments from Lake Malta. Maximum concentration in water samples was noted for nonylphenol at 0.56 μg L–1. No octylphenol nor its ethoxylates were found in the water samples.

While the cationic surfactants were purified, the anionic surfactants were used as received. In the former case, surface tension and conductivity measurements lead to the same cmc values. In the latter case, measuring the specific conductivities (bulk property) proved to be superior compared to measuring the surface tensions (surface property) because the presence of highly surface active impurities creates a pronounced minimum in the surface tension isotherm, which makes it impossible to determine an accurate value for the cmc. On the other hand, these impurities do not influence the conductivities, i.e. that the conductivities can be used to determine cmc values of impure and technical grade ionic surfactants, respectively. Moreover, an evaluation of the specific conductivities allows for the determination of the degree of micelle ionization (alpha) of the ionic surfactant solutions and thus provides additional useful information.

Dimethylsulfoxide (DMSO) and acetonitrile (AN) were used as cosolvents added to water. The ability of NaCl to lower the CMC of CTAB in water was inhibited by DMSO and AN. Thermodynamic parameters of micellization ΔH0m, ΔS0m, and ΔG0m were evaluated according to the pseudo-phase model. The contribution of DMSO and AN in the micellization process of CTAB in aqueous electrolyte solutions were discussed in terms of the observed thermodynamic properties.

Rhéologie
SurfactantsIndex. décimale : 668.1 Agents tensioactifs : savons, détergents Résumé : Mixtures of the cationic, cellulose based polyelectrolyte JR 400 and the anionic surfactant sodium dodecylbenzene sulfonate (LAS) have been used to control the rheological behaviour of aqueous solutions. Around charge equilibrium precipitation takes place, but both for the surfactant-rich and the polymer-rich side homogeneous solutions are formed. In these monophasic regions the rheology depends strongly on the mixing ratio between the two components and highly viscous systems can be obtained on the polyelectrolyte rich side upon the addition of relatively small amounts of surfactant. Here the viscosity increases by more than four orders of magnitude before reaching the phase boundary of precipitation. Small-angle neutron scattering (SANS) showed the formation of an interconnected network of rodlike aggregates composed of a polyelectrolyte/surfactant complex, which explains the observed high viscosity due to the high degree of interconnection by the polyelectrolyte.

Surfaces -- NettoyageIndex. décimale : 668.1 Agents tensioactifs : savons, détergents Résumé : In today's modern world, convenience is key. This need for convenience permeates most basic tasks, such as cleaning our homes. All of us seek ways to lessen the time we devote to keeping our homes clean while maintaining a sanitary home environment. We all know, however, that cleaning is a time-consuming and often laborious task.
Despite the recent undoubted progress in the quality of household care products, there is still room for cleaning products to fully leverage cutting-edge developments in chemical innovations in order to make cleaning a more efficient task. In response to this, Clariant developed Aristocare Smart, a high-performance, multi-purpose hydrophilic polymer.
Aristocare Smart is an additive that can be added to all types of cleaners to deliver not only high-quality results but also to maintain the cleanliness of surfaces for longer. Cleaners that integrate this new polymer can now combat soils, including soap scum and calcareous build-up, effortlessly and significantly reduce spotting and streaking from product and water residues.
Aristocare Smart forms a thin layer that "smooths" when applied to a surface, thereby preventing droplets of water and soit from "sticking " to the surface. In addition, Aristocare Smart leads to a consistent cleaner dis-tribution, which provides an ordered light reflection and thus leads to a streak-free and shiny surface. Aristo-care Smart hydrophilizes surfaces, which allows faster and longer-lasting water drainage from surfaces. Cleaning products with improved water drainage leave less water residue on surfaces and, as a result, less spotting once dried. This novel polymer allows long-term surface hydrophilization, even after consecutive rinsing with tap water, without leading to long-term build-up.Note de contenu : - TESTS AND RESULTS : Effortless soap scum removal - Anti-streaking - Fast water drainage and limescale prevention
