solvantsIndex. décimale : 668.1 Agents tensioactifs : savons, détergents Résumé : The United Nations Climate Change Conference – COP26, held in Glasgow in November 2021, was a major event bringing together leaders from all countries to agree on how to step up global actions to solve the climate crisis, and there was one topic at the top of their agenda : the need to reduce greenhouse gas emissions.
It is easy to imagine that this same target is also at the top of the short-medium term objectives lists of the most important industries across different markets, and consumer goods companies are definitely not behind. The need to be environmentally friendly clearly affects Home & Personal care formulations, and it is up to the chemical industry to deliver solutions that will allow us – as formulators and as consumers – to have lower carbon footprint products.
At Solvay, sustainability leads us in the development of new solutions and lower carbon footprint solutions that can replace petrochemical based chemistry are at the heart of our initiatives. In this context, Solvay has developed the Augeo line of solvents that can deliver up to 60% lower carbon footprint compared to glycol ethers, without compromising on high performance for cleaning products.Note de contenu : - MATERIALS & METHODS : Cleaning with effort methodology (ASTM D4488) - Cleaning with effort methodology (ASTM D4488)

Tension superficielleIndex. décimale : 668.1 Agents tensioactifs : savons, détergents Résumé : Detergency is the removal of soil through a complex process involving interactions between the wash liquor, the soil and the substrate. In this paper, we describe the results of our preliminary investigations into polymer-surfactant interactions, focusing on primary detergency in laundry applications. We have studied the interaction between surfactants typically used in laundry formulations and hydrophobically modified polycarboxylate polymers. These polymers are a series of copolymers of acrylic acid and styrene with varying molar amounts of the styrene hydrophobe. The effect of a partial replacement of the surfactant by these polymers was characterized by the static surface tension measurements. These measurements predict that these polymers should aid in primary detergency. Primary detergency tests show that these polymers in combination with the anionic surfactant sodium-dodecylbenzenesulfonate (LAS) improve detergency when the LAS level is below its critical micelle concentration (CMC). Even more remarkable is the oily soil release improvement with the non-ionic alcohol ethoxylate (AE) surfactant, C13-15,7 E0, even above the CMC. This is possibly due to a change in micelle shape, which favours spontaneous emulsification, and subsequent soil release by mechanical action.

Langues : Anglais (eng) Catégories : Surfactants Tags : Surfactant amphotérique Concentration critique Micelle Paramètres interaction Index. décimale : 668.1 Agents tensioactifs : savons, détergents Résumé : The influence of chain length on the composition of mixed micelles in binary mixtures of N,N-dimethyldodecylamine oxide (DDAO) and sodium decyl-, sodium dodecyl-and sodium tetradecylsulfate (abbreviated as SDeS, SDS ans STS, respectively) has been determined at 30°C. From the surface tension measurements, the critical micelle concentration (cmc) data were measured as a function of mixing composition. Cmc-values were then analyzed according to regular solution model. The composition of mixed micelles, the interaction parameter (B) and the activity coefficients were evaluated from the regular solution model for the all anionic-amphoteric mixed systems. The interaction parameter values indicated a synergistic interaction between DDAO and the three anionic surfactants at all mole fractions to be due to an overall attractive interaction in the mixed micelles. The strength of the interaction between tha amphoteric surfactant and the sodium alkyl sulfate in three mixed systems obeys the following order : SDeS/DDAO>SDS>DDAO>STS>DDAO suggesting that the decrease in the length of anionic surfactant alkyl chain results in a stronger interaction with DDAO. On the other hand, the viscosity data reveals a viscosity increasing trend of STS/DDAO>SDS/DDAO>SDeS/DDAO. Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=6251

Titre : Synergistic effect of cationic-nonionic surfactants on simultaneous separation of phenylalanine and tyrosine Type de document : texte imprimé Auteurs : A. Mohammad, Auteur ; N. Haq, Auteur Année de publication : 2010 Article en page(s) : p. 248-253 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Acides aminés Les acides aminés (ou aminoacides) sont une classe de composés chimiques possédant deux groupes fonctionnels : à la fois un groupe carboxyle –COOH et un groupe amine –NH2. Parmi ceux-ci, les acides α-aminés se définissent par le fait que leur groupe amine est lié à l'atome de carbone adjacent au groupe acide carboxylique (le carbone α), ce qui leur confère la structure générique H2N–CHR–COOH, où R représente la chaîne latérale, qui identifie l'acide α-aminé.
Les acides α-aminés jouent un rôle fondamental en biochimie comme constituants élémentaires des protéines : ils polymérisent en formant des liaisons peptidiques qui aboutissent à de longues chaînes macromoléculaires appelées peptides.

SurfactantsIndex. décimale : 668.1 Agents tensioactifs : savons, détergents Résumé : A new thin layer chromatographic system comprising of silica gel impregnated with 0.1% aqueous solution (below CMC) of nonionic surfactant Brij-35 as stationary phase and 0.1% aqueous solution (below CMC) of cationic surfactant (cetrimide) as eluent has been found most suitable for the separation of closely related amino acids (phenylalanine and tyrosine) from their mixture. Effect of substitution of Brij-35 by cetrimide and sodium cholate has been examined to assess the impact of charge of impregnant on the chromatographic behavior of analytes. The changes brought about by the impregnation in the structure and homogeneity of silica gel have been studied by scanning electron microscopy (SEM) and fourier transform infra-red spectroscopy (FTIR) techniques. Optimizations of concentration of Brij-35 and cetrimide in the stationary and mobile phases respectively and the effect of bed height on the separation have also been examined. Chromatographic parameters like ΔRF, separation factor (α) and resolution (RS) were calculated for the separation of tyrosine from phenylalanine and separation mechanism have been proposed. The limits of detection for phenylalanine and tyrosine were found to be 0.25 and 0.23 μg respectively. The proposed method studied is simple, rapid and free from the use of volatile organic solvents.

Titre : Synthèse de tensioactifs biosourcés issus de polysaccharides anioniques Type de document : texte imprimé Auteurs : Thierry Benvegnu, Auteur Année de publication : 2023 Article en page(s) : p. 123-124 Note générale : Fiche N° 105 - Bibliogr. Langues : Français (fre) Catégories : Polysaccharides Les polysaccharides (parfois appelés glycanes, polyosides, polyholosides ou glucides complexes) sont des polymères constitués de plusieurs oses liés entre eux par des liaisons osidiques.
Les polyosides les plus répandus du règne végétal sont la cellulose et l’amidon, tous deux polymères du glucose.
De nombreux exopolysaccharides (métabolites excrétés par des microbes, champignons, vers (mucus) du ver de terre) jouent un rôle majeur - à échelle moléculaire - dans la formation, qualité et conservation des sols, de l'humus, des agrégats formant les sols et de divers composés "argile-exopolysaccharide" et composites "organo-minéraux"(ex : xanthane, dextrane, le rhamsane, succinoglycanes...).
De nombreux polyosides sont utilisés comme des additifs alimentaires sous forme de fibre (inuline) ou de gomme naturelle.
Ce sont des polymères formés d'un certain nombre d'oses (ou monosaccharides) ayant pour formule générale : -[Cx(H2O)y)]n- (où y est généralement x - 1). On distingue deux catégories de polysaccharides : Les homopolysaccharides (ou homoglycanes) constitués du même monosaccharide : fructanes, glucanes, galactanes, mannanes ; les hétéropolysaccharides (ou hétéroglycanes) formés de différents monosaccharides : hémicelluloses.
Les constituants participant à la construction des polysaccharides peuvent être très divers : hexoses, pentoses, anhydrohexoses, éthers d'oses et esters sulfuriques.
Selon l'architecture de leur chaîne, les polysaccharides peuvent être : linéaires : cellulose ; ramifiés : gomme arabique, amylopectine, dextrane, hémicellulose et mixtes : amidon.
