The solubility of dioctyl sodium sulfosuccinate in water is 14 g/L at 25 °C, increasing to 55 g/L at 70 °C. [31] 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). It also is highly soluble in glycerol, although this is a rather polar solvent.
The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.
The tables below provides information on the variation of solubility of different substances (mostly inorganic compounds) in water with temperature, at one atmosphere pressure. Units of solubility are given in grams of substance per 100 millilitres of water (g/100 ml), unless shown otherwise.
It is a key intermediate raw material in the production of dioctyl sulfosuccinate (DOSS, docusate) salts, used medically as laxatives and stool softeners, and in many other applications as versatile surfactants. [2] [3] [4]
Structure of sodium sulfosuccinate esters. Sodium sulfosuccinate esters are organic compounds with the formula NaO 3 SCH(CO 2 R')CH 2 CO 2 R where R and R' can be H or alkyl groups. They comprise a large class of surfactants and emulsifiers used in cosmetics, pharmaceuticals, and cleaning agents. They are colorless salts.
Bis(2-ethylhexyl) phthalate (di-2-ethylhexyl phthalate, diethylhexyl phthalate, diisooctyl phthalate, DEHP; incorrectly — dioctyl phthalate, DIOP) is an organic compound with the formula C 6 H 4 (CO 2 C 8 H 17) 2.
A notable surfactant that has been witnessed to form vesicles is AOT (Dioctyl sulfosuccinate sodium salt). These micelles and vesicles are relatively new discoveries; however, they have been utilized to transport agents within microfluidic systems, [46] revealing future applications for microfluidic transports.

Salting out (also known as salt-induced precipitation, salt fractionation, anti-solvent crystallization, precipitation crystallization, or drowning out) [1] is a purification technique that utilizes the reduced solubility of certain molecules in a solution of very high ionic strength.
