Description
Technical Field
The invention belongs to the technical field of daily chemical products, and particularly relates to a special liquid detergent composition for a transparent concentrated dish washing machine.
Background
Compared with the manual tableware washing, the automatic dish washing machine has the advantages of saving physical strength, convenience and water saving, and has multiple functions of cleaning, disinfecting, drying, storing and the like, so that the automatic dish washing machine can fully meet the requirement that people hope to be liberated from simple and repeated housework.
The main stream of spray arm type dish washer, the cleaning and the dirt removal on the tableware mainly rely on the jet action of powerful water flow in three-dimensional space, the heat energy action of the heating water and the oil and dirt removal action of the cleaning agent. The manual dishwashing detergent cannot be used in the dishwasher because the presence of the foam reduces the pressure of the water jet of the spray arm of the dishwasher, because the manual dishwashing detergent generates a large amount of foam, and further because the anionic surfactant contained in the manual dishwashing detergent generates a large amount of foam, and the foam is more difficult to remove due to the presence of the foam stabilizing component.
Solid detergents are more common in the field of dishwasher detergents, mainly because of their better stability and less development difficulty. However, solid products can be dusty during manufacture or use; the fast dissolution properties of solid detergents are extremely important, especially under fast wash mode washing conditions, where residual solid powders may leave the consumer with the perception that dishes remain, requiring additional re-washing; solid detergents also have a certain odor, which is repelled by some consumers; in addition, the current Chinese market is mainly hand dishwashing detergents, so consumers are mostly aware of the dishwashing detergents as transparent and clear liquids. Therefore, it is very necessary to develop a dishwasher-specific liquid detergent.
Generally, solid detergents contain alkaline builders, chelating agents, anti-redeposition agents (usually polymers), enzyme preparations, surfactants, etc., which are not in direct contact in the solid detergent composition or which do not present compatibility issues under anhydrous conditions, but compatibility issues must be considered in liquid products, which also makes development of dishwasher-specific liquid detergents more difficult.
In addition, although the liquid product has no dust problem, the dishwasher-specific liquid detergent cannot be added with an anionic surfactant or an excessive amount of a zwitterionic surfactant due to the limitation of the foaming problem, and a nonionic surfactant with low or no foaming is preferred. However, the compatibility of pure nonionic systems without anionic surfactants with respect to metal ions, enzyme preparations, chelating agents, polymers, etc. may deteriorate, especially in systems with a moisture content of less than 20%; the chelating agent, the enzyme preparation and the polymer are important functional components in the detergent for the dish-washing machine, and the chelating agent, the enzyme preparation and the polymer are generally substances with better hydrophilicity and are difficult to obtain stable homogeneous appearance in a concentration system with lower moisture content; in addition, the enzyme preparation raw material usually needs to add metal ions as a stabilizer of the enzyme preparation, so the addition of the enzyme preparation can reduce the stability of the pure nonionic system, because the concentrated pure nonionic system has poor compatibility with the metal ions. It can be seen that the transparency and stability of the transparent concentrated liquid detergent for dish-washing machine is a big problem, and it is easy to generate gel, layer, precipitate, etc., so the use of such functional components in the concentrated system is limited, and the limitation is especially obvious in high-concentration products or single-dose condensed bead products encapsulated by PVA film.
In conclusion, the provision of a concentrated liquid detergent for dish-washing machines with high transparency and good stability has become a serious difficulty in industrial research.
