Used in print (Jay C. Harris and John R. Van Wazer, "Detergent...)As_is well_known , detergent actives belong_to the chemical class consisting_of moderately high molecular_weight and highly polar molecules which exhibit the property of forming micelles in solution . ( 3 ) For anionics , these micelles appear to be roughly spherical assemblages in which the hydrocarbon tails come together so that the polar groups ( the ionized ends ) face outward towards the aqueous continuous phase . Related_to micelle formation is the technologically important ability of detergent actives to congregate at oil_water_interfaces in such a manner that the polar ( or ionized ) end of the molecule is directed towards the aqueous phase and the hydrocarbon chain towards the oily phase .
