Application

Dioctyl sulfosuccinate sodium salt (DOSS) can be used as an anionic surfactant:
  • To prepare microemulsion with sodium salt of 3-(cyclohexylamino)-2-hydroxy-1-propanesulfonic acid (CAPSO) for the electrophoresis detection of natural and synthetic estrogens.
  • To develop reverse micelles.
  • To enhance the electrical conductivity and cell attachment in polycaprolactone fumarate and polypyrrole (PCLF–PPy) composite materials.
