Description

Low-temperature quick-washing active oxygen whitening laundry gel composition Technical Field The invention belongs to the technical field of daily chemical washing, and particularly relates to a low-temperature rapid-washing active oxygen whitening laundry gel composition. Background The addition of oxygen-based bleaching components to laundry detergents is an important means of achieving stain removal, whitening and disinfection. Sodium percarbonate acts as a common oxygen-based bleaching agent, the action of which depends on decomposition in water and release of active oxygen. However, the efficiency of this process is closely related to temperature. In low temperature water below 20 ℃, especially 10-15 ℃, the reaction rate of hydrogen peroxide decomposition to generate peroxy hydroxyl ions of an effective bleaching component is extremely low, so that the oxidation stain removal power is seriously insufficient. Although industry usually attempts to improve low temperature performance by adding bleach activators such as tetraacetylethylene diamine, it is still common to rely on prolonging the washing time or increasing the water temperature in order to achieve acceptable cleaning effect, which is fundamentally contradictory to the energy-saving and time-saving procedures such as "quick washing", "cold water washing" and the like which are popular in the current washing machines. Therefore, developing a system capable of activating active oxygen in low temperature water quickly and efficiently is a key to meeting modern washing habits. On the other hand, the combination of the active oxygen system with biological enzyme preparations such as protease, lipase and the like is recognized as an ideal direction for improving the comprehensive decontamination performance of the detergent. The enzyme preparation can specifically catalyze and decompose protein and grease stains. However, the active oxygen component slowly releases active oxygen having strong oxidizing property during storage, which damages the active center of the enzyme protein, resulting in rapid inactivation of the enzyme. This chemical incompatibility makes the development of concentrated laundry products with both efficient active oxygen bleaching and bio-enzyme catalyzed soil release capabilities a great challenge. The prior art often adopts a physical isolation or a compartmentalization design, but increases the complexity and cost of the process, and the stable coexistence is difficult to realize in a highly concentrated single liquid phase system of laundry gel beads. In addition, as consumer demand for product safety, environmental protection, and versatility increases, market expectations for laundry products have exceeded basic cleaning. Many existing active oxygen washing formulas have the disadvantages of high pH value, possibly not being friendly to skin, partial products contain phosphorus auxiliary agents or optical fluorescent whitening agents, and have single functions or limited effects in the aspects of bacteriostasis durability, peculiar smell removal and fabric softening and nursing after washing. Therefore, there is a need to design a low temperature fast-washing active oxygen whitening laundry bead composition. Disclosure of Invention In order to overcome the defects in the prior art, a low-temperature rapid-washing active oxygen whitening laundry gel composition is provided.
