Sodium stearate Chemische Eigenschaften,Einsatz,Produktion Methoden

  S24/25:Berührung mit den Augen und der Haut vermeiden.

• Beschreibung

  Sodium stearate is the sodium salt of stearic acid. This white solid is the most common soap. It is found in many types of solid deodorants, rubbers, latex paints, and inks. It is also a component of some food additives and food flavorings.

• Chemische Eigenschaften

  white to off-white powder

• Chemische Eigenschaften

  Sodium stearate, NaC18H35O2, white solid, soluble, froth or foam upon shaking the water solution (soap), formed by reaction of NaOH and stearic acid (in alcoholic solution) and evaporating. Used as a source of stearate.

• Verwenden

  Pharmaceutic aid (emulsifying and stiffening agent). In glycerol suppositories; also in toothpaste; as waterproofing agent.

• Verwenden

  β-Lactamase inhibitor

• Verwenden

  Characteristic of soaps, sodium stearate has both hydrophilic and hydrophobic parts, the carboxylate and the long hydrocarbon chain, respectively. These two chemically different components induce the formation of micelles, which present the hydrophilic heads outwards and their hydrophobic (hydrocarbon) tails inwards, providing a lipophilic environment for hydrophobic compounds. It is also used in the pharmaceutical industry as a surfactant to aid the solubility of hydrophobic compounds in the production of various mouth foams.

• Verwenden

  Sodium Stearate is the sodium salt of stearic acid. it functions as a binder, emulsifier, and anticaking agent. it is used as a plasticizer in chewing gum base.

• Verwenden

  sodium stearate is a fatty acid used as a waterproofing agent. Sodium stearate is one of the least allergy-causing sodium salts of fatty acids. It is non-irritating to the skin.

• Vorbereitung Methode

  Sodium stearate is produced as a major component of soap upon saponification of oils and fats. The percentage of the sodium stearate depends on the ingredient fats. Tallow is especially high in stearic acid content (as the triglyceride), whereas most fats only contain a few percent. The idealized equation for the formation of sodium stearate from stearin (the triglyceride of stearic acid) follows :
  (C₁₈H₃₅O₂)₃C₃H₅ → C₃H₅(OH)₃ + 3 C₁₇H₃₅CO₂Na
  Purified sodium stearate can be made by neutralizing stearic acid with sodium hydroxide.

• Definition

  ChEBI: An organic sodium salt comprising equal numbers of sodium and stearate ions.

• Sicherheitsprofil

  Poison by intravenous route. When heated to decomposition it emits toxic fumes of Na2O.

• läuterung methode

  It is better to prepare it by adding a slight excess of octadecanoic acid to ethanolic NaOH, evaporating and extracting the residue with dry Et2O. [Beilstein 2 III 1003.]
