  • Chemische Eigenschaften White crystalline flakes
  • Chemische Eigenschaften Sodium lauryl sulfate consists of white or cream to pale yellowcolored crystals, flakes, or powder having a smooth feel, a soapy, bitter taste, and a faint odor of fatty substances.
  • Verwenden Sodium dodecyl sulfate is an emulsifier and whipping aid that has a solubility of 1 g in 10 ml of water. It functions as an emulsifier in egg whites. It is used as a whipping aid in marshmallows and angel food cake mix. It also functions to aid in dissolving fumaric acid.
  • Verwenden Anionic detergent
  • Verwenden hydrophilic tablet lubricant
  • Verwenden Wetting agent, detergent, especially in the textile industry. Electrophoretic separation of proteins and lipids. Ingredient of toothpastes.
  • Definition An anionic surfactant, usually a mixture of sodium alkyl sulfates that lowers surface tension of aqueous solutions.
  • Vorbereitung Methode Sodium lauryl sulfate is prepared by sulfation of lauryl alcohol, followed by neutralization with sodium carbonate.
  • Allgemeine Beschreibung White to pale yellow paste or liquid with a mild odor. Sinks and mixes with water.
  • Air & Water Reaktionen Insoluble in water.
  • Reaktivität anzeigen DODECYL SULFATE is incompatible with strong oxidizers. Sodium dodecyl sulfate is also incompatible with cationic materials and with acids with pH below 2.5. Salts, basic, such as DODECYL SULFATE, are generally soluble in water. The resulting solutions contain moderate concentrations of hydroxide ions and have pH's greater than 7.0. They react as bases to neutralize acids. These neutralizations generate heat, but less or far less than is generated by neutralization of the bases in reactivity group 10 (Bases) and the neutralization of amines. They usually do not react as either oxidizing agents or reducing agents but such behavior is not impossible.
  • Health Hazard Inhalation of dust causes sneezing and coughing. Ingestion of large amounts causes irritation of stomach. Dust irritates eyes and may cause burns on prolonged contact. Contact with skin causes some irritation; continued exposure to water solution causes drying out and cracking.
  • Brandgefahr Flash point data for Sodium dodecyl sulfate are not available; however, Sodium dodecyl sulfate is probably combustible.
  • Pharmazeutische Anwendungen Sodium lauryl sulfate is an anionic surfactant employed in a wide range of nonparenteral pharmaceutical formulations and cosmetics.
    It is a detergent and wetting agent effective in both alkaline and acidic conditions. In recent years it has found application in analytical electrophoretic techniques: SDS (sodium dodecyl sulfate) polyacrylamide gel electrophoresis is one of the more widely used techniques for the analysis of proteins; and sodium lauryl sulfate has been used to enhance the selectivity of micellar electrokinetic chromatography (MEKC).
  • Kontakt-Allergie This anionic detergent is widely used in cosmetics and industry. As a skin irritant agent, SLS can be used in several dermatological applications. It is also a good indicator of excited skin during patch testing.
  • Sicherheitsprofil Poison by intravenous and intraperitoneal routes. Moderately toxic by ingestion. An experimental teratogen. A human skin irritant. An experimental eye and severe skin irritant. A mild allergen. Mutation data reported. When heated to decomposition it emits toxic fumes of SO, and Na2O. See also ESTERS and SULFATES.
  • Sicherheit(Safety) Sodium lauryl sulfate is widely used in cosmetics and oral and topical pharmaceutical formulations. It is a moderately toxic material with acute toxic effects including irritation to the skin, eyes, mucous membranes, upper respiratory tract, and stomach. Repeated, prolonged exposure to dilute solutions may cause drying and cracking of the skin; contact dermatitis may develop.(3) Prolonged inhalation of sodium lauryl sulfate will damage the lungs. Pulmonary sensitization is possible, resulting in hyperactive airway dysfunction and pulmonary allergy. Animal studies have shown intravenous administration to cause marked toxic effects to the lung, kidney, and liver. Mutagenic testing in bacterial systems has proved negative.
    Adverse reactions to sodium lauryl sulfate in cosmetics and pharmaceutical formulations mainly concern reports of irritation to the skin or eyes following topical application.
    Sodium lauryl sulfate should not be used in intravenous preparations for humans. The probable human lethal oral dose is 0.5–5.0 g/kg body-weight.
    LD50 (mouse, IP): 0.25 g/kg
    LD50 (mouse, IV): 0.12 g/kg
    LD50 (rat, oral): 1.29 g/kg
    LD50 (rat, IP): 0.21 g/kg
    LD50 (rat, IV): 0.12 g/kg
  • Lager Sodium lauryl sulfate is stable under normal storage conditions. However, in solution, under extreme conditions, i.e. pH 2.5 or below, it undergoes hydrolysis to lauryl alcohol and sodium bisulfate.
    The bulk material should be stored in a well-closed container away from strong oxidizing agents in a cool, dry place.

  • läuterung methode Purify this detergent by Soxhlet extraction with pet ether for 24hours, followed by dissolution in acetone/MeOH/H2O 90:5:5(v/v) and recrystallisation [Politi et al. J Phys Chem 89 2345 1985]. It has been purified by two recrystallisations from absolute EtOH, aqueous 95% EtOH, MeOH, isopropanol or a 1:1 mixture of EtOH/isopropanol to remove dodecanol, and dried under vacuum [Ramesh & Labes J Am Chem Soc 109 3228 1987]. SDS has also been purified by repeatedly foaming whereby a 0.15% aqueous solution is made to foam and the foam is discarded, then the H2O is removed in vacuo and the residue is diluted to the required concentrations [see Cockbain & McMullen Trans Faraday Soc 47 322 1951] or by liquid-liquid extraction [see Harrold J Colloid Sci 15 280 1960]. Dry it over silica gel. For DNA work it should be dissolved in excess MeOH passed through an activated charcoal column and evaporated until it crystallises out. It has also been purified by dissolving in hot 95% EtOH (14mL/g), filtering and cooling, then drying in a vacuum desiccator. Alternatively, it is crystallised from H2O, vacuum dried, washed with anhydrous Et2O and dried in vacuum again. These operations are repeated five times [Maritato J Phys Chem 89 1341 1985, Lennox and McClelland J Am Chem Soc 108 3771 1986, Dressik J Am Chem Soc 108 7567 1986]. [Beilstein 1 IV 1847.]
  • Inkompatibilitäten Sodium lauryl sulfate reacts with cationic surfactants, causing loss of activity even in concentrations too low to cause precipitation. Unlike soaps, it is compatible with dilute acids and calcium and magnesium ions.
    Sodium lauryl sulfate is incompatible with salts of polyvalent metal ions, such as aluminum, lead, tin or zinc, and precipitates with potassium salts. Solutions of sodium lauryl sulfate (pH 9.5–10.0) are mildly corrosive to mild steel, copper, brass, bronze, and aluminum.
  • Regulatory Status GRAS listed. Included in the FDA Inactive Ingredients Database (dental preparations; oral capsules, suspensions, and tablets; topical and vaginal preparations). Included in nonparenteral medicines licensed in the UK. Included in the Canadian List of Acceptable Non-medicinal Ingredients.
