A reduced-odor polyol composition for gastrointestinal lavage of a mammal comprises a polyol and at least one acid salt formed from a reaction between a basic catalyst and citric acid. The reduced-odor polyol composition is produced by providing at least one alkylene oxide； providing at least one initiator； reacting the at least one alkylene oxide with the at least one initiator in the presence of a basic catalyst to produce a polyol； and neutralizing the basic catalyst with citric acid, thereby forming at least one acid salt and producing the reduced-odor polyol composition.
