The Behavior of Aqueous Solution of Sodium Deoxycholate in Capillary Flow

Primary micelles form secondary, polymer-like aggregates in a capillary flow of aqueous solution of sodium deoxycholate (SDC). The formation of the polymer-like aggregate is promoted by mechanical action, degradation being simultaneously caused by shearing stress. The viscosity of the SDC solution in the capillary flow attains equilibrium value between polymerization and degradation. The viscosity changes a great deal with the time of observation and pH. Under given conditions the SDC solution behaves as a non-Newtonian fluid obeying a power-law.
