Abstract
Liquid detergent compositions are described. The liquid detergent can contain defined mixtures of anionic, nonionic and cationic surfactants. The surfactants can be present at concentrations ranging from about at least 15% to about 60%. A useful ingredient in the detergent includes an alkylamine ethoxylate. This ethoxylate should have at least about 5 moles of ethoxylate per mole of the surfactant. Additional ingredients in the detergent include alkylamines and polyalkylene glycols, which facilitate achieving stable, pourable and pumpable liquid detergents that are highly concentrated. Other ingredients may also be included in the liquid detergent.
