Pure dodecyl benzene sulfonate is dissolved in water, water solubility should be good

Sodium dry dodecyl benzene sulfonate should be insoluble in ethanol, especially without water ethanol, but because of mutualAmong the aqueous and ethanol, there will be some x (123]
sodium dodecyl benzene sulfonate is dissolved in methanol, ethylene glycol, and propylene glycol these hydrophilic groups, but the solubility is not very large

Those DMF, DMSO also solubate

water insoluble solvent, benzene, toluene, cyclohexane, haloane, ether, ketone, ester such solvent, completely insoluble

Isn't it a washing powder?Add hot, you can dissolve
