Chemische Eigenschaften
Docusate sodium is a white or almost white, waxlike, bitter tasting, plastic solid with a characteristic octanol-like odor. It is hygroscopic and usually available in the form of pellets, flakes, or rolls of tissuethin material.
Chemische Eigenschaften
white solid, often supplied as an aqueous solution
Verwenden
Dioctyl sulfosuccinate sodium salt is a wetting and emulsifying agent that is slowly soluble in water, having a solubility of 1 g in 70 ml of water. It functions as a wetting agent in fumaric acid-containing powdered fruit drinks to help the acid dissolve in water. It is used as a stabilizing agent on gums at not more than 0.5% by weight of the gum. It is used as a flavor potentiator in canned milk where it improves and maintains the flavor of the sterilized milk during storage. It also functions as a processing aid in the manufacture of unrefined sugar. It is also termed sodium dioctylsulfosuccinate.
Verwenden
Sodium salt of Docusate, used for the treatment of constipation, acting as a laxative or stool softener. Also used in the synthesis of electrospun fibres for tailored and controlled antibiotic drug release.
Verwenden
dioctyl sodium sulfosuccinate is a mild surfactant used as a cleans ing agent.
Verwenden
Forms reverse micelles in hydrocarbon solvents; Suitable for the solubilization of the major myelin transmembrane proteolipid
Verwenden
anticholinergic, treatment of motion sickness
Vorbereitung Methode
Maleic anhydride is treated with 2-ethylhexanol to produce dioctyl maleate, which is then reacted with sodium bisulfite.
Definition
ChEBI: Sodium docusate is an organic sodium salt.

Allgemeine Beschreibung
Odorless colorless to white waxy solid. Sinks and mixes slowly with water.
Air & Water Reaktionen
Mixes slowly with water.
Reaktivität anzeigen
Docusate sodium causes foaming and spreading of water. Assists in putting out fires by water. [USCG, 1999].
Health Hazard
Liquid is strong irritant to eye and may irritate skin by removing natural oils. Ingestion causes diarrhea and intestinal bloating.
Brandgefahr
Behavior in Fire: Causes foaming and spreading of water. Assists in putting out fires by water.
Flammability and Explosibility
Non flammable
Pharmazeutische Anwendungen
Docusate sodium and docusate salts are widely used as anionic surfactants in pharmaceutical formulations. Docusate sodium is mainly used in capsule and direct-compression tablet formulations to assist in wetting and dissolution.
Sicherheitsprofil
Poison by intravenous route. Moderately toxic by ingestion and intraperitoneal routes. A skin and severe eye irritant. See also ESTERS. When heated to decomposition it emits toxic fumes of SOx and Na2O.
Sicherheit(Safety)
Docusate salts are used in oral formulations as therapeutic agents for their fecal softening and laxative properties. As a laxative in adults, up to 500mg of docusate sodium is administered daily in divided doses; in children over 6 months old, up to 75 mg in divided doses is used. The quantity of docusate sodium used as an excipient in oral formulations should therefore be controlled to avoid unintended laxative effects. Adverse effects associated with docusate sodium include diarrhea, nausea, vomiting, abdominal cramps, and skin rashes. As with the chronic use of laxatives, the excessive use of docusate sodium may produce hypomagnesemia.
Docusate salts are absorbed from the gastrointestinal tract and excreted in bile; they may cause alteration of the gastrointestinal epithelium. The gastrointestinal or hepatic absorption of other drugs may also be affected by docusate salts, enhancing activity and possibly toxicity. Docusate sodium should not be administered with mineral oil as it may increase the absorption of the oil.
LD50 (mouse, IV): 0.06 g/kg
LD50 (mouse, oral): 2.64 g/kg
LD50 (rat, IP): 0.59 g/kg
LD50 (rat, oral): 1.9 g/kg
Solubility in organics
Dioctyl sodium sulfosuccinate (DSS) is the dioctyl ester of sodium sulfosuccinate (bis-2-ethyl-hexyl sodium sulfosuccinate). It dissolves slowly in water; at 25°C to the extent of 1.5 gm/100cc; at 70°C, 5.5 gm/100cc. It dissolves in oils, hydrocarbons, fats and waxs by heating above 75°C and remains in solution when cooled to room temperature. At room temperature, it is readily soluble in most organic solvents, both polar and non-polar. soluble in carbon tetrachloride, petroleum ether, naphtha, xylene, dibutyl phthalate, liquid petroleum, acetone, alcohol, vegetable oils.
Lager
Docusate sodium is stable in the solid state when stored at room temperature. Dilute aqueous solutions of docusate sodium between pH 1–10 are stable at room temperature. However, at very low pH (<1) and very high pH (>10) docusate sodium solutions are subject to hydrolysis.
The solid material is hygroscopic and should be stored in an airtight container in a cool, dry place.
läuterung methode
Dissolve it in MeOH and the inorganic salts which precipitate are filtered off. Water is added and the solution is extracted several times with hexane. The residue is evaporated to one-fifth its original volume, *benzene is added and azeotropic distillation is continued until no water remains. The solvent is evaporated. The white residual solid is crushed and dried in vacuo over P2O5 for 48hours [El Seoud & Fendler J Chem Soc, Faraday Trans 1 71 452 1975]. [Beilstein 4 IV 114.] It solubilises major myelin trans membrane proteolipids, and forms reverse micelles in hydrocarbon solvents.
Inkompatibilitäten
Electrolytes, e.g. 3% sodium chloride, added to aqueous solutions of docusate sodium can cause turbidity. However, docusate sodium possesses greater tolerance to calcium, magnesium, and other polyvalent ions than do some other surfactants. Docusate sodium is incompatible with acids at pH < 1 and with alkalis at pH > 10.
Regulatory Status
GRAS listed. Included in the FDA Inactive Ingredients Database (IM injections; oral capsules, suspensions, and tablets; also topical formulations). Included in nonparenteral medicines licensed in the UK. Included in the Canadian List of Acceptable Non-medicinal Ingredients.
