ABSTRACT:
A liquid dishwashing detergent composition for hand washing of dishes in cold water includes a synthetic organic nonionic detergent, a cationic surface active agent, a water soluble C.sub.21 dicarboxylic salt and an aqueous medium. The proportion of the combination of nonionic detergent and cationic surface active agent is a detersive proportion, useful to remove fatty deposits on dishes, and the proportion of the C.sub.21 dicarboxylic salt is sufficient to improve the detersive action in cold water of the combination of nonionic detergent and cationic surfactant so that the composition better removes fatty deposits on dishes being washed. Preferably, the liquid dishwashing detergent composition comprises 10 to 20% of a nonionic detergent, which is a condensation product of 3 to 20 moles of ethylene oxide with one mole of higher fatty alcohol of 10 to 16 carbon atoms per mole, 10 to 20% of ##STR1## wherein R is a hydrocarbyl chain of 8 to 22 carbon atoms and X is a halogen selected from the group consisting of chlorine and bromine, 1 to 5% of a salt of C.sub.21 dicarboxylic acid, selected from the group consisting of sodium, potassium, ammonium and triethanolamine salts, and mixtures thereof, and 50 to 80% of water.
Also within the invention is a process for washing dishes in which the mentioned detergent compositions or their components are employed in a cold wash water. Such a process is energy conserving, allowing the washing of dishes, even those containing solid fatty deposits, in facilities where hot water is not available. Additionally, such hand dishwashing may be kinder to the housewife's hands.
