TrisiloxaneIndex. décimale : 668.1 Agents tensioactifs : savons, détergents Résumé : In a solvent free system, hydrolitically stable nonionic surfactants, trisiloxane grafted oligo(éthylène oxide), were synthesized by hydrosilylation of heptamethyltrisiloxane with allyl-oligo(EO) series. The structures of intermediate and products were confirmed by infrared spectroscopy and 1H nuclear magnetic resonance spectroscopy. Surface activity, foaming property and wetting ability of the surfactants, were also investigated. The results show that the prepared surfactants exhibited excellent surface activity and wetting ability. Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=6054

Tests de toxicitéIndex. décimale : 668.1 Agents tensioactifs : savons, détergents Résumé : Neem (Azadirecta indica) and Karanj (Pongamia pinnata) oils are ecofriendly, non-toxic, completely biodegradable with antiviral, antifungal, and antibacterial properties. The dark green colour Copper(II) soaps derived from Neem and Karanj oil, their greenish brown complexes with ligand 2-amino-6-methyl benzothiazole containing nitrogen and sulphur have been synthesized and characterized by elemental analysis. IR and NMR of complexes suggest that the complexation has taken place successfully. From the analytical data the stoichiometry of the complexes has been observed to be 1:1 (metal-ligand). Copper soaps and their complexes are good anti-fungal agents. The fungi toxicities of the oils, soaps and complexes of neem and karanj have been investigated. The results indicate that the strain of Candida species is susceptible towards complexes of benzothiazole. Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=5458

The derivatives were characterized by means of FT-IR and elemental analysis, and evaluated for laundry anti-redeposition performance, alone and in systems with mannanase and/or cellulase enzymes. Optimum anti-redeposition performance was observed at degrees of substitution of around 0.15. Mannanase was found to have a negative effect on sulfoethyl locust bean gum derivatives’ performance although a system comprising sulfoethyl locust bean gum derivative and cellulase was found to be complementary.

Surfactants -- SynthèseTags : 'Surfactants cationiques' 'Chlorure stéaryl morpholinium' palmitoyl Synthèse Index. décimale : 668.1 Agents tensioactifs : savons, détergents Résumé : Two new surfactants (stearoyl morpholinium chloride and palmitoyl morpholinium chloride) were synthesized in two steps. In the first step, chloride acids were reacted with morpholine salt for producing morpholinium normal penta decyl ketone and morpholinium normal hepta decyl ketone. In the second step, the obtained products were reacted with HCl to produce suitable surfactants. The synthesis products in each steps were analyzed by Nuclear magnetic resonance (NMR), Fourier transform infrared spectrometry (FTIR), and elemental analysis. Also, the kinetic of the reactions were investigated. It has been shown that the synthesis reaction of the first step, the low rate step, follows a first order for two surfactants. The properties of two surfactants were investigated for anti-static and surface tension reduction. It was found that the hydrocarbon chain length is the main factor which has an effect on the properties of surfactants.

Oléique, AcideL'acide oléique vient du latin oleum et veut dire huile. C'est le plus abondant des acides gras monoinsaturés à chaîne longue dans notre organisme. Sa formule chimique brute est C18H34O2 (ou CH3(CH2)7CH=CH(CH2)7COOH). Son nom IUPAC est acide cis-9-octadécénoïque, et son nom court de lipide est 18:1 cis-9. La forme saturée de cet acide est l'acide stéarique.
On le symbolise par les nombres 18:1 pour indiquer qu'il possède 18 atomes de carbone et une liaison éthylénique. Pour indiquer la position de la double liaison, on préfère indiquer le nombre de carbones entre le dernier carbone (n° 18) et le carbone où commence la double liaison (n° 9), d'où 18 - 9, qu'on écrit n - 9, en désignant par n le nombre de carbones de la chaîne. L'acide oléique est donc un acide gras insaturé, plus précisément monoinsaturé.
La double liaison agit sur la forme de la molécule et des triglycérides qu’elle forme avec le glycérol. Comme la molécule ne peut pas pivoter autour de C = C, la chaîne est beaucoup moins flexible que l’acide stéarique et ne peut pas former de boule. Les molécules des esters de cet acide sont beaucoup moins compactes que la tristéarine: ces sont des huiles.
À la température de notre corps c'est un liquide (huile), qui ne se solidifie qu'à 13,4 °C.

Tensions (chimie)Index. décimale : 668.1 Agents tensioactifs : savons, détergents Résumé : This paper describes an efficient method for the synthesis of long chain alkylamido imidazolines by the reaction of diethylenetriamine and oleic acid under non-solvent microwave irradiation using calcium oxide as support and their comparison with conventional thermal condensation process. Synthesized imidazolines were then quaternized by using dimethylsulfate as a quaternizing agent and isopropanol as a solvent, to produce cationic imidazolinium salts which were evaluated for yield and cationic content. The instrumental techniques, viz. FT-IR and 1H-NMR verified the formation of imidazolines and its subsequent quaternization. The surface active and performance properties of cationic imidazolines in terms of c.m.c., surface tension, dispersability, emulsion stability, softening, rewettability and detergency were also reported.
