Abstract

The invention discloses a detergent s pecialfor a household automatic dishwasher. Thedetergent comprises a first mixture and a second mixture, the first mixture comprises a surfactant, an activator, a chelating agent and a multifunctional dispersant, and the second mixture comprises a bleaching agent and a filler. The detergent special for the automatic dishwasher, provided by the invention, is relatively high in stability, adopts a non-phosphorus formula, is simple in process, is non-corrosive to glass, has a good decontamination effect, particularly has a good removal effect on tea stains, and can remove peculiar smell in the dish-washing machine. Concretely, calcium and magnesium ions in water and iron ions in tea leaves are chelated through the detergent to disintegrate stains, and peculiar smell in the dishwasher is removed through a bleaching component and a bleaching activator TAED.

Description

technical field [0001] The invention relates to the field of daily necessities chemical industry, in particular to a special detergent for household automatic dishwashers and a preparation method thereof.
