The two alcohols form a synergistic blend, enabling a significant reduction of the viscosity of the polyethoxylated alcohol sulfate composition. Also provided is an embodiment of a method for modifying the rheology of polyethoxylated alcohol sulfate by use of a mono-alcohol and a polyol simultaneously. Finally provided is an embodiment of a detergent composition which is prepared by use of the polyethoxylated alcohol sulfate composition described herein, in addition to other commonly known ingredients. ## Claims ### Claim 1 A polyethoxylated alcohol sulfate blend consisting essentially of: a polyethoxylated alcohol sulfate having Formula (I): R′—O—(C2H4O)n-SO3M′ (I) wherein R′ is a C8-C20 alkyl group, n is from 1 to 20, and M′ is a salt-forming cation, preferably, R′ is C10-C18 alkyl, n is from 1 to 15, and M′ is sodium, potassium, ammonium, alkylammonium, or alkanolammonium, a mono-alcohol, a polyol, and water;
