Abstract
The invention relates to the field of daily chemicals, and provides a special detergent composition for a high-efficiency dish washing machine. The special detergent composition for the dish washing machine comprises 0.1-20% of reducing agent and 0.1-50% of protein denaturant in percentage by weight. According to the invention, the reducing agent is used in the conventional combination, and the protein denaturant is added, so that the protein denaturant and the reducing agent can play a synergistic effect, egg steaming stains can be effectively removed, and other stain types of stains can be effectively cleaned, such as: minced meat, spinach, eggs, milk, black tea, oatmeal porridge, butter and the like, and has the advantages of quick action time, high safety, stable performance, difficult decomposition of oxygen-free bleaching components and good effect on pigment stains.
Description
Technical Field
The invention relates to the field of daily chemicals, in particular to a special detergent composition for a high-efficiency dish washing machine.
Background
The cleaning of the dishes in the household kitchen has been a source of annoyance to the consumer. The dietary structure of domestic chinese style food and beverage is abundant, and not only the spot composition is complicated, difficult washing, and the tableware is various moreover, the difference is big, especially the tableware through high temperature cooking, if: bowl for steaming eggs, earthenware pot for cooking porridge, rice cooker for drying and crusting rice, dinner plate for steaming fish, dinner ware for seafood curry chafing dish and the like, tableware in oven and the like (or additionally comprising coffee cup and tea cup). In a high-temperature cooking environment, double bonds, carbon-carbon single bonds and carbon-hydrogen bonds in grease can be oxidized to generate various hydrocarbon radicals, and then the radicals are subjected to chain type oxidative polymerization and oxidative decomposition to form dirt with strong viscosity to be attached to the surface of tableware. Meanwhile, the high-temperature polymerized oil stain is combined with denatured and crosslinked protein, sugar, starch and the like, so that the binding force between stains and the surface of tableware is firmer and the tableware is more difficult to clean.
With the advent of dish washing machines, it has the advantages of saving physical strength, convenience, water conservation, and has multiple functions of cleaning, sterilizing, drying, and storing, etc., and is well received by consumers. However, for some stains cooked at high temperature, the stains are difficult to clean thoroughly by using a dishwasher at present, and often need to be washed once again by hands, and when the stains are washed by hands, the stubborn stains are removed by increasing mechanical force, such as using steel wire balls, wiping with force, prolonging soaking time and the like. Thus, the requirement of "hands free" of the consumer cannot be really met.
In addition, in order to remove colored stains such as tea stains, coffee stains and the like, bleaching systems such as oxygen bleaching and chlorine bleaching are often adopted. Wherein, sodium percarbonate and sodium perborate are commonly used for oxygen bleaching, but the oxygen bleaching is easy to decompose in the shelf life of the product, so that the bleaching effect is reduced, and the bag is expanded; the chlorine bleach is usually sodium dichloroisocyanurate and the like, has strong corrosivity and is easy to corrode tableware and machinery.
Therefore, a special detergent for a dishwasher, which has strong capability of removing stubborn stains, enables the dishwasher to clean all tableware and does not have the defects of common oxygen bleaching and chlorine bleaching, is needed.
