Abstract
Aqueous, liquid hard surface detergent compositions having good filming/streaking characteristics contain amido zwitterionic detergent surfactant; linear cosurfactant; hydrophobic perfume; stabilizing additive that is C.sub.2-3 fatty acid and/or C.sub.2-6 alkane diol to help stabilize the hydrophobic perfume, especially as a microemulsion; optionally, cleaning solvent, monoethanolamine and/or other specific beta-aminoalkanols, etc. Preferred formulas do not contain large amounts of builders and/or other materials that contribute to bad spotting and filming and said formulas are suitable for general purpose cleaning including cleaning of glass.
