ABSTRACT Viscous aqueous solutions are prepared which maintain a certain viscosity range over a predetermined period of time (i.e., induction period) and which there- after break, i.e., decrease in viscosity over a very short period of time. The viscous aqueous solution comprises a polysaccharide having an ability to thicken water and dispersed or dissolved in the aqueous solution an effec- tive quantity of an organic ester which, at a temperature at which it is desired to break the viscous solution, hy- drolyzes over a delayed period of time to form an acid which degrades the polysaccharide, thus causing a split- ting of the polysaccharide chain and a decrease in the viscosity of the solution. r
