  • Many detergent-active structured liquids are also capable of suspending particulate solids such as detergency builders and abrasive particles.
  • SUBSTITUTE SHEET micelles both of these being isotropic.
  • structured (anisotropic) systems can form. They are referred to respectively, by various terms such as rod- micelles, planar lamellar structures, lamellar droplets and liquid crystalline phases.
  • rod- micelles planar lamellar structures
  • lamellar droplets and liquid crystalline phases.
  • different workers have used different terminology to refer to the detergent ⁇ -active structures which are really the same.
