Dodécyl sulfate de sodiumLe laurylsulfate de sodium (LSS) ou dodécylsulfate de sodium (SDS) est un détergent et tensioactif ionique fort, couramment utilisé en biochimie et biologie moléculaire.
C'est un composé à ne pas confondre avec le laureth sulfate de sodium.
La concentration micellaire critique du SDS varie de 0,007 à 0,01 mol/L dans l'eau à 25°C.
Le dodécylsulfate de sodium (en anglais, Sodium Dodecyl Sulfate ou SDS ou/ NaDS), de formule C12H25NaO4S, aussi connu sous le nom de laurylsulfate de sodium (en anglais, sodium lauryl sulfate ou SLS), est un tensioactif ionique qui est utilisé dans les produits ménagers tels que les dentifrices, shampooings, mousses à raser ou encore bains moussants pour ses effets épaississants et sa capacité à créer une mousse, il est également repris comme additif alimentaire par le codex alimentarius (E487).
La molécule est composée d’une chaîne de 12 atomes de carbone, rattachée à un groupement sulfate conférant à la molécule les propriétés amphiphiles requises pour un détergent. Le SDS est préparé par sulfonation du dodécanol (alcool de lauryl, C12H25OH), suivie par une neutralisation par du carbonate de sodium. Le SDS est utilisé aussi bien dans les procédés industriels que pour les produits cosmétiques destinés au grand public.

SynergieIndex. décimale : 668.1 Agents tensioactifs : savons, détergents Résumé : Biosurfactants are gaining importance due their large potential for industrial applications and their eco-friendly nature. The properties of biosurfactants can vary with their structure which is dependent upon strain, cultivation conditions and carbon source. A mannosylerythritol lipid (MEL) is one of the simplest biosurfactants with a well-defined structure produced by Pseudozyma antarctica (ATCC 32657). The study includes the surfactant properties of MEL produced on soybean oil with sucrose as substrate. MEL showed surface activity at very low concentrations. The various properties were explained on the basis of the structural similarity between MEL and Gemini surfactant. The performance properties of SLS like foaming, emulsification and wetting were improved when SLS was partially substituted (5– 20%) by MEL. Based on the study, MEL can be used in various cosmetic products like shaving creams, skin creams and lotions, where MEL will not only enhance foaming property but also provide moisturizing and healing properties on skin.

SurfactantsIndex. décimale : 668.1 Agents tensioactifs : savons, détergents Résumé : In this study palmitoyl piperidinium chloride and stearoyl piperidinium chloride surfactants were synthesized by two steps. The synthesized products in each step were analyzed by Nuclear Magnetic Resonance (NMR), Fourier Transform Infrared Spectrometry (FTIR), and elemental analysis. The properties of two surfactants were investigated, including surface tension (γ), critical micelle concentration (CMC), effectiveness (Ï€cmc), efficiency (pC20), and anti-static properties. It was found that the number of methylene groups (-CH2-) in the hydrophobic chain has important effect on the properties of surfactants. Increasing the methylene groups enhances the ability of surfactant to act as effective surface tension agents in many applications. Furthermore, stearoyl piperidinium chloride showed that it can be used as a good capping agent in the microemulsion synthesis of MnS nanoparticles.

Spectrométrie de masseIndex. décimale : 668.1 Agents tensioactifs : savons, détergents Résumé : The interest in biosurfactant has increased considerably due to their large potential for industrial applications. Rhamnolipid is the simplest class of biosurfactants with well defined structure. The main obstacle in commercialization of biosurfactant especially rhamnolipids is the higher cost of the production that can be reduced by use of inexpensive carbon substrates like glycerol that is readily available from commercial fat-splitting process in the form of sweet water (up to 20% w/v) at very low cost. The composition and structure of various components in crude rhamnolipids synthesized by of Pseudomonas aeruginosa (ATCC 10145) on sweet water, were determined using TLC, HPLC and LC\MS. The crude product showed two distinct components having structure Rha2C10C10 and Rha2C10C12 at 85.45 wt.% and 14.55 wt.% respectively. The Rha2C10C10 was more efficient and effective in surface tension reduction up to 23.5 mN/m than other components. Crude rhamnolipids showed better emulsifying power than its individual components. The crude rhamnolipids showed better foam stability than sodium lauryl sulfate (SLS) at lower concentrations (0.05 to 0.002% w/v). It also enhanced and stabilized the foam produced by SLS at 0.01 to 0.025% of rhamnolipids. Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=11946

SurfactantsIndex. décimale : 668.1 Agents tensioactifs : savons, détergents Résumé : Two structural studies of the following two liquid crystals systems: [(C12EO4 + 1% SDS)/H2O, ca. 25–85 wt.% surfactant] and [(C12EO8 + 1% SDS)/H2O, ca. 40–71 wt.% surfactant] have been investigated. Both previous systems contain similar amount of Sodium Dodecyl Sulphate, SDS. It has been found that there are two mesophases at 25°C: the lamellar Lα and the hexagonal H1. Their structural parameters were determined using small angle X-ray scattering (SAXS) patterns. The mesophases study of the Lα and H1 regions allows the evolution description of the surfactant chains conformation. The geometrical parameters of the Lα and H1 mesophases such as the thickness of hydrocarbon core of the lamellar mesophase and the diameter of rods forming the hexagonal structure were calculated. In the lamellar, Lα and the hexagonal, H1 mesophases, the surface area per molecule and the thickness of the hydrocarbon core exhibited a little sensitivity change toward concentration. The thickness of the ethoxy groups was estimated in Lα and H1 mesophases as a function of surfactant concentration in (C12EO4 + 1% SDS)/H2O and (C12EO8 + 1% SDS)/H2O systems at 25°C, respectively.
