Abstract
Abstract Heavy-duty liquid detergents containing a neutralization system comprising bleach compatible bicyclic tertiary amines and imines; anionic surfactant; ethoxylated nonionic surfactant; optional quaternary ammonium, amine, amide, or amine oxide surfactant; preferably fatty acid and/or polycarboxylate builders; and a solvent system comprising ethanol, polyol and/or water. The compositions are isotropic liquids providing a high level of detergency performance.
