The design of the proportion of active ingredients in dishwasher capsules should focus on decontamination efficiency, environmental adaptability and formula stability. The following is an analysis of the key ingredients, their proportion range and functions:
Detergent
The content of detergent AIDS in dishwashers can be as high as 30% to 60%. Their functions are mainly reflected in chelating effect, alkaline medium effect, synergistic effect and dispersion effect. For instance, chelation can chelate the calcium and magnesium ions contained in water and keep them in a dissolved state, preventing the formation of precipitates of insoluble calcium and magnesium salts that could contaminate tableware. The action of alkaline media is conducive to the occurrence of saponification reactions of oils and fats, promoting the emulsification, dispersion and removal of oil dirt.
Nonionic surfactant
In dishwasher detergents, the content of surfactants is relatively low, but their role cannot be ignored. The main function of nonionic surfactants is to wet and help disperse dirt, and prevent it from redepositing on the surface of tableware. Due to the special working environment of the dishwasher, the surfactant used must be a low-foaming and oxidation-resistant nonionic surfactant to avoid excessive foam reducing the spray pressure and thus affecting the cleaning efficiency.
Enzyme preparations
Enzyme preparations are another important active ingredient in dishwasher capsules, which can enhance the decontamination effect. The selected enzyme preparations must be those that can maintain stable activity in an alkaline liquid environment and at a relatively high cleaning temperature, such as protease and amylase, etc. Enzyme preparations have the characteristic of being highly efficient in trace amounts in detergents. They can specifically catalyze and decompose stubborn stains such as proteins and starches, making them easier to remove.
Polymer dispersant
High molecular polymer dispersants can chelate calcium and magnesium ions contained in water and keep them in a dissolved state, preventing the formation of insoluble calcium and magnesium salt precipitates that could contaminate tableware, while reducing the amount of chelating agents added. Its dispersion ability is highly efficient, and it can meet the usage requirements with a small amount, which is conducive to optimizing the formula and cost of dishwasher capsules.
Oxidizing agent
Oxidants mainly oxidize and decompose difficult-to-wash colored stains such as tea stains and coffee stains, making them dissolve in water and be washed away. In dishwasher detergents, chlorine-free oxidants such as sodium percarbonate and sodium perborate are generally used to meet the requirements of environmental protection and green development.
