Tension superficielleIndex. décimale : 668.1 Agents tensioactifs : savons, détergents Résumé : Surfactants are the most important ingredients in laundry detergents, hand dish washing liquids and shampoos. It is a major challenge for the industry today to identify alternative materials that are biodegradable, based on renewable resources and that show reasonable cost-performance effectiveness. Biosurfactants are an emerging class of surfactants produced by microorganisms in processes usually running at low temperatures and without large amounts of waste or by-products, therefore complying with the rules of green chemistry and potentially resulting in a lower carbon footprint than conventional surfactants. We show in our work which biosurfactants can meet or even surpass conventional surfactants today when it comes to properties like interfacial tension reduction and wetting. Taking into account that further optimization and tailoring of materials, unique physicochemical properties and efficient production processes are within reach, the future perspectives for the broader use of biosurfactants are bright.

The surface properties such as the critical micelle concentration CMC, minimum surface tension γCMC, effectiveness of the surface tension reduction Ï€CMC, maximum surface excess Γmax and surface area per molecule Amin have been determined by means of surface tension measurements. As expected, these surfactants have good surface activities than those conventional monomeric ones (dodecyl trimethyl ammonium chloride (DTAC)) and the spacer plays an important role in the surface properties. Under experimental conditions, surface parameters decreases with the increase of carbon number of the spacer the except analogue with a benzene ring due to its inflexibility. The aggregation ability of some practically used reactive azodyes (C. I. Reactive Red 198) in aqueous solutions and the prepared surfactants was investigated using UV-visible spectroscopic methods. The spectroscopic studies were extended in order to determine the effect of molecular structure of the surfactants on the aggregative properties of C. I. Reactive Red 198 (RR 198). The aggregation behaviour of the RR 198 in solutions and in the presence of additives is related to their apparent deviations from Beer’s law and aggregation number (N). The aggregation constant (Kn) of the monomer/dimer equilibrium was calculated. The aggregate structures and the nature of the interacting pairs in this dye were discussed using Kasha exciton theory.

Langues : Anglais (eng) Tags : 'Sulfate de propoxylate d'alcool' Alfoterra 'Tension interfaciale très réduite' 'Récupération améliorée l'huile' (EOR) Adsorption Surfactant 'Flottation surfactant' 'Chimie la flottation' Index. décimale : 668.1 Agents tensioactifs : savons, détergents Résumé : This investigation considers branched alkyl alcohol propoxylated sulfate surfactants as candidates for chemcial enhanced oil recovery (EOR) applications. Results show that these anionic surfactants may be preferred candidates for EOR as they can be effective at creating low interfacial tension (IFT) at dilute concentrations, without requiring an alkaline agent or cosurfactant. In addition, some of the formulations exhibit a low IFT at high salinity, and hence may be suitable for use in more saline reservoirs. Adsorption tests onto kaolinite clay indicate that the loss of these surfactants can be comparable to or greater than other types of anionic surfactants. Surfactant performance was evaluated in oil recovery core flood tests. Selected formulations recovered 35–50% waterflood residual oil even with dilute 0.2 wt% surfactant concentrations from Berea sandstone cores.

Textiles et tissus -- LavageIndex. décimale : 668.1 Agents tensioactifs : savons, détergents Résumé : After a successful shopping trip, you are delighted with your newly purchased clothes. To preserve this joy for as long as possible, your textiles should be washed in a way that not only keeps them clean but also protects them. The original colors should fast, clothing should not discolor. Dye transfer inhibitors in color detergents play an important role in preserving a garment's original colors. They prevent color molecules in the washing liquor from transferring to another textile and discoloring it.
The special polymer Sokalan HP 56 K is a particularly powerful dye transfer inhibitor as a result of its chemical structure (vinylpyrrolidone/vinylimidazole copolymer). It can be easily incorporated in the various liquid detergent formulations as well as in modern pods, capsules, and pouches. As a result of its special dye transfer inhibition, it also supports "color care" claims such as "color protection," "maintenance of color brilliance," and " less pre-sorting" of laundry.
For washing conditions that resemble those of consumers, a new test method was developed, which is presented below. It demonstrates that by using Sokalan® HP 56 K, light and dark textiles can be washed together and the colors do not lose their brilliance.
In addition to the new test method, the following section shows how the surfactant system in formulations can be optimized to counteract negative effects caused by dye transfer inhibitors interacting with anionic surfactants.Note de contenu : - New tests method to support "color care" claims
