I want to know density of liquid soap/detergent-alcohol-water solution. Any ternary or pseudoternary description of components will be helpful. technically some sol-gel formation or colloidal formation may occur, so the mixture may not be a true solution.
One may start Sodium Stearate/Palmitate/Oleate as soap or Sodium Lauryl/Laureth/Pareth sulfonate/sulfate as detergent, ethanol or isopropanol to be alcohol.
I know that soaps have specific gravity around .9-1, sodium polytungstate (historically thallium organic salts called clerici solution as well as some heavy organics) have been material of choice for heavy mineral separation, but I am thinking of using simple organic binary/ternary solutions to cross the 2800 kg/m^3 threshold for heavy minerals. Zinc chloride is toxic, so I left it out; halocarbons are not safe either. Sucrose-water solution(or glass?)reaches barely 1.4 specific gravity before viscosity rises to extremely high value for filtration.
Not for the use in mineralogy where precise specific gravities of the heavy liquids are mandatory to achieve good results.
Maybe these mixtures find applicaton in some kind of flotation where other physical parameters such as surface tension, hydrophobic interaction play an important part... But this is not my cup of tea. You need an expert on this matter.

Sodium hydroxide can add additional density if you do not need high pH you can use Na2SiO4 or Sodium aSodium carbonatecarbonate, citric acid to adjust final pH.
