Docusate is the common chemical and pharmaceutical name of the anion bis(2-ethylhexyl) sulfosuccinate, also commonly called dioctyl sulfosuccinate (DOSS).

Salts of this anion, especially docusate sodium, are widely used in medicine as laxatives and as stool softeners, by mouth or rectally.
Docusate sodium is on the World Health Organization's List of Essential Medicines. 
In 2018, DOS 70 was the 142nd most commonly prescribed medication in the United States, with more than 4 million prescriptions.
Some studies claim that docusate is not more effective than a placebo for improving constipation.
Other docusate salts with medical use include those of calcium and potassium.

Docusate salts are also used as food additives, emulsifiers, dispersants, and wetting agents, among other uses


DOS 70 is an anionic surfactant. 
DOS 70 enables formulations with creamy texture and good foaming properties despite the high oil content. 
DOS 70 is compatible with anionic, amphoteric & non-ionic surfactants like cocamidopropyl betaine and/or sodium laureth sulfate. 
Diethylhexyl Sodium Sulfosuccinate does not require any additional solubilizer.
DOS 70 finds application in formulating body washes, shampoos with high oil content (up to 50%) and cleansing formulations.
DOS 70 is a surfactant that exhibits excellent penetrating abilities, acid and hard water stability. 
DOS 70 acts as a wetting/ penetrant, surfactant and dispersing agent. 

Diethylhexyl Sodium Sulfosuccinate acts as an alkyl and alkyl ether sulfosuccinate surfactant. 
Diethylhexyl Sodium Sulfosuccinate is a foam booster. Diethylhexyl Sodium Sulfosuccinate exhibits excellent dispersing effect both in aqueous and non-aqueous dispersion. 
DOS 70 is used in shower and bath products, shampoo and liquid soaps.

History
Sodium docusate was patented in 1937 by Coleman R. Caryl and Alphons O. Jaeger for American Cyanamid, which commercialized it for many years as a detergent under the brand name Aerosol OT.
DOS 70s use for the treatment of constipation was first proposed in 1955 by James L. Wilson and David G. Dickinson, and quicky popularized under the name Doxinate.

Medical use
Constipation
The main medical use of docusate sodium is to treat constipation, acting as a laxative and stool softener. 
In painful anorectal conditions such as hemorrhoid and anal fissures, it can help avoid pain caused by straining during bowel movements.

When administered by mouth, a bowel movement often occurs in 1 to 3 days, while rectal use may be effective within 20 minutes.
Sodium docusate is recommended as a stool softener for children.

However, DOS 70s effectiveness for constipation is poorly supported by evidence.
Multiple studies have found docusate to be no more effective than a placebo for improving constipation.
Others have found DOS 70 to be less useful for the treatment of chronic constipation than psyllium.
The medication may be given to people who are receiving opioid medication, although prolonged use may cause irritation of the gastrointestinal tract.

Other medical uses
Docusate sodium, when used with ear syringing, may help with earwax removal, particularly in the case of impaction.
Sodium docusate is also used as a lubricant in the production of tablets and as an emulsifier in topical preparations and other suspensions.

Precautions and contraindications
Docusate sodium is approved and recommended as safe during pregnancy and breastfeeding.
Docusate is not recommended in people with appendicitis, acute abdomen, or ileus.
When taken by mouth DOS 70 should be ingested with plenty of water.


Mechanism of action
Docusate sodium works by allowing more water to be absorbed by the stool.
Docusate does not stay in the gastrointestinal tract, but is absorbed into the bloodstream and excreted via the gallbladder after undergoing extensive metabolism.

The effect of docusate may not necessarily be all due to DOS 70s surfactant properties. 
Perfusion studies suggest that docusate inhibits fluid absorption or stimulates secretion in the portion of the small intestine known as the jejunum.

Pharmaceutical brand names
In the U.S., docusate sodium for pharmaceutical use is available under multiple brand names: Aqualax, Calube, Colace, Colace Micro-Enema, Correctol Softgel Extra Gentle, DC-240, Dialose, Diocto, Dioctocal, Dioctosoftez, Dioctyn, Dionex, Doc-Q-Lace, Docu Soft, Docucal, Doculax, Docusoft S, DOK, DOS, Doss-Relief, DSS, Dulcolax - Stool Softener (not to be confused with another drug marketed under the Dulcolax brand, bisacodyl, which is a stimulant laxative), Ex-Lax Stool Softener, Fleet Sof-Lax, Genasoft, Kasof, Laxa-basic, Modane Soft, Octycine-100, Pedia-Lax, Preferred Plus Pharmacy Stool Softener, Regulax SS, Sulfalax Calcium, Sur-Q-Lax, Surfak Stool Softener, and Therevac-SB. Generic preparations are also available.
In the UK, dioctyl sodium sulfosuccinate is sold under the brand name Docusol (Typharm Ltd) and DulcoEase (Boehringer Ingelheim).
In Australia, dioctyl sodium sulfosuccinate is sold as Coloxyl and Coloxyl with senna.
In India, preparations include Laxatin by Alembic, Doslax by Raptakos Laboratories, Cellubril by AstraZeneca, and Laxicon by Stadmed.

Other uses
DOS 70 is used as a surfactant in a wide range of applications, often under the name Aerosol-OT.
DOS 70 is unusual in that DOS 70 is able to form microemulsions without the use of co-surfactants, and DOS 70 has a rich variety of aqueous-phase behavior including multiple liquid crystalline phases.[24]

Food additive
DOS 70 has been approved by the US FDA as a "generally recognized as safe" (GRAS) additive.
DOS 70 is used in a variety of food products, as a surface active agent, stabilizer, thickener, wetting agent, processing aid, solubilizing agent, emulsifier, and dispersant. 
The highest amount found in food products is 0.5% by weight, which include pasteurized cheese spreads, cream cheeses and salad dressings.
The FDA also approved its use as a wetting agent or solubilizer for flavoring agents in carbonated and non-carbonated drinks at levels up to 10 parts per million.

Microencapsulation
Sodium docusate is the most widely used surfactant in reverse micelle encapsulation studies.

Non-medical brand names
As a surfactant, docusate sodium is or has been commercialized under many brand names, including DSSj Aerosol OT, Alphasol OT, Colace, Complemix, Coprol, Dioctylal, Dioctyl-Medo Forte, Diotilan, Diovac, Disonate, Doxinate, Doxol, Dulsivac, Molatoc, Molofac, Nevax, Norval, Regutol, Softili, Solusol, Sulfimel DOS, Vatsol OT, Velmol, and Waxsol

Chemistry
Structure and properties
The structural formula of the docusate anion is R−O−C(=O)−CH(SO−3)−CH2−C(=O)−O−R, where R is the 2-ethylhexyl group H3C−(CH2)3−C(−CH2−CH3)H−CH2−. 

The conjugate acid can be described as the twofold carboxylate ester of sulfosuccinic acid with 2-ethylhexanol.

The compound is a white, wax-like, plastic solid, with an odor suggestive of octyl alcohol. 
DOS 70 starts to decompose at about 220 °C.

Solubility of dioctyl sodium sulfosuccinate in water is 14 g/L at 25 °C, increasing to 55 g/L at 70 °C.
Solubility is better in less polar solvents: 1:30 in ethanol, 1:1 in chloroform and diethylether, and practically unlimited in petroleum ether (25 °C). 
DOS 70 also is highly soluble in glycerol, although this is a rather polar solvent. 
DOS 70 is also highly soluble in xylene, oleic acid, acetone, diacetone alcohol, methanol, isopropanol, 2-butanol, methyl acetate, ethyl acetate, furfurol, and vegetable oils.

The ester groups are easily cleaved under basic conditions, but are stable against acids.

Synthesis
Sodium dioctyl sulfosuccinate can be obtained by treating dioctyl maleate with sodium bisulfite. 
The bisulfite anion adds to the double bond:

−CH=CH− + HSO−3 → −CH(−SO−3)−CH2−

Marine species
DOS 70 is of low toxicity for crustaceans such as the hermit crab Clibanarius erythropus and the shrimp Crangon crangon. 
Toxicity for molluscs varies widely, with 48-hour LD50 found between 5 mg/l for the common limpet and 100 mg/l for the common periwinkle. 
Various species of phytoplankton have an LD50 around 8 mg/l.

In a 2010 study, dioctyl sodium sulfosuccinate exhibited higher toxicity against bacteria (Vibrio fischeri, Anabaena sp.) and algae (Pseudokirchneriella subcapitata) than did a number of fluorinated surfactants (PFOS, PFOA, or PFBS). 
Measuring bioluminescence inhibition of the bacteria and growth inhibition of the algae, the LD50 were in the range of 43–75 mg/l. 
Combinations of the fluorinated compounds with dioctyl sodium sulfosuccinate showed mid to highly synergistic effects in most settings, meaning that such combinations are significantly more toxic than the individual substances.

DOS 70, CAS No. 577-11-7, is the sodium salt of the diester of a 2-ethylhexyl alcohol and sulfosuccinic acid 

Other names for this compound include: 1,4-Bis(2-Ethylhexyl)Sulfobutanedioate, Sodium Salt; Butanedioic Acid, Sulfo-1,4-Bis(2-Ethylhexyl) Ester, Sodium Salt; Di-(2-Ethylhexyl)Sodium Sulfosuccinate; Docusate Sodium; Sodium Di-(2-Ethylhexyl)Sulfosuccinate; Sulfosuccinic Acid, Di-(2-Ethylhexyl) Ester, Sodium Salt; and Sodium Dioctyl Sulfosuccinate . 
In Japan DOS 70 is referred to as Di(2-Ethylhexyl)Sodium Sulfosuccinate.

Dioctyl Sodium Sulfosuccinate has a molecular weight of 444.56 and appears as a waxy solid. 
DOS 70 is soluble in both water and organic solvents, especially in water and water-miscible solvent combinations. 
DOS 70s water solubilities as a function of temperature are: 15 g/1 at 25°C, 23 g/1 at 40°C, 30 g/1 at 50°C, and 55 g/1 at 70°C. 
Acid and neutral solutions of Dioctyl Sodium Sulfosuccinate are stable; alkaline solutions hydrolyze . 
Results from mass, ’H-NMR, and 13C-NMR spectroscopy are available.

Maleic anhydride is reacted with 2-ethylhexanol to produce bis(2-ethylhexyl)maleate. 
This, in turn, is combined with sodium bisulfite under conditions conducive to the formation of the sulfonate structure through rearrangement with an accompanying saturation of the olefinic bond, producing Dioctyl Sodium Sulfosuccinate

Analytic Methods 
Ahuja and Cohen (1983) described a number of methods available for the assay of Dioctyl Sodium Sulfosuccinate. 
Titration assays for anionic surfactants can be used to determine Dioctyl Sodium Sulfosuccinate : a two-phase mixed indicator titration using 2:3 (v:v) chloroform : 1- nitropropane solvent system and an extractive titration technique using carbethopendecinium bromide. 
Colorimetric analysis methods involving extraction with ethyl violet, bis[2-(2-pyridylazo)-5-diethylaminophenolato] cobalt (III) ion, 1-(4-nitrobenzyl)-4-(4-diethylaminophenylazo)pyridinium bromide, and bis[2-(5-chloro-2-pyridylazo)-5-diethylaminophenolato] cobalt (III) chloride are also described. 
Turbidimetric, polarographic, and nitrogen blowing techniques are also available. 

Impurities
According to the National Formulary (1980), calculated on an anhydrous basis, Dioctyl Sodium Sulfosuccinate should contain between 99 and 100.5% (inclusively) C2oH37Na07S; water should be no more than 2.0%; arsenic, 3 ppm; heavy metals, 0.001%; bis(2-ethylhexyl)maleate, 0.4%.

Dioctyl sulfosuccinate is of major importance in the reverse micellar solubilization of biomolecules like proteins, peptides, amino acids and, in particular, enzymes. 
DOS 70 is even possible to solubilize whole bacteria cells.
The concept of reverse micellar solubilization with dioctyl sulfosuccinate is based on DOS 70s property of aggregating in organic solvents like isooctane and forming micelles with a reverse orientation so that e.g. proteins, dissolved in water, may be enclosed. 
The selectivity of this process can be controlled.
A whole range of enzymes – e.g. tyrosinases, lipoxygenases, lipases and catalases – has already been investigated in dioctyl sulfosuccinate reverse micelles.
The reverse micellar solubilization with dioctyl sulfosuccinate is extraordinarily interesting for biotechnological applications.

Available forms
Docusate sodium is administered orally or rectally; in tablets, capsules, suppositories and enemas. 
DOS 70 is also used as an emulsifier and dispersant in topical preparations.

Other uses
20px
This section needs expansion. 
You can help by adding to DOS 70. 
Dioctyl sodium sulfosuccinate is a pesticide used popularly for crops of olives, almonds, wine grapes, corn and oranges.
DOS 70 is used as an excipient in the production of tablets (as a lubricant) and suspensions (as an emulsifier).
DOS 70 is the most widely used surfactant in reverse micelle encapsulation studies.
Docusate sodium, when used in conjunction with irrigation, is also an effective means of earwax removal.

Contraindications
Docusate is contraindicated in patients with appendicitis, acute abdomen or ileus. 
DOS 70 is not suitable for the treatment of chronic constipation.

Physical and chemical properties
Solubility of dioctyl sodium sulfosuccinate in water is 1:70 (14 g/l) at 25 °C, increasing to 1:20 at 70 °C. 
Solubility is better in less polar solvents: 1:30 in ethanol, 1:1 in chloroform and diethylether, and practically unlimited in petroleum ether (25 °C). 
DOS 70 is also highly soluble in glycerol, although this is a rather polar solvent.

The ester groups are easily cleaved under basic conditions, but are stable against acids.

Pharmacokinetics and mechanism of action
Docusate does not stay in the gastrointestinal tract, but is absorbed into the bloodstream and excreted via the gallbladder after undergoing extensive metabolism.

The effect of docusate may not necessarily be all due to DOS 70s surfactant properties. 
Perfusion studies suggest that docusate inhibits fluid absorption or stimulates secretion in the portion of the small intestine known as the jejunum.

Interactions
Docusate should not be used in addition to mineral oil as the emulsifier will result in mineral oil being absorbed rather than functioning as a lubricant for the bowel walls, possibly resulting in foreign body granulomas. 
The substance might also increase resorption of other drugs, for example dantron (1,8-dihydroxyanthraquinone).
