Description

Biological complex enzyme-mediated low-temperature stain-removing microcapsule slow-release fragrance-retaining laundry detergent Technical Field The invention belongs to the technical field of detergents, and particularly relates to a biological compound enzyme-mediated slow-release fragrance-retaining microcapsule laundry detergent for removing stains at a low temperature. Background With the improvement of life quality of residents, the enhancement of environmental protection and energy conservation awareness and the diversified development of clothes materials, the laundry detergent gradually replaces the traditional washing powder, and is widely applied in the daily chemical washing field. Compared with washing powder, the liquid laundry detergent has the characteristics of high dissolution speed, small damage to clothes and the like, can be suitable for various materials such as cotton, hemp, silk, wool and the like, and is suitable for various washing scenes. At present, the cleaning function of the laundry detergent mainly depends on the synergistic effect of a surfactant system and a functional auxiliary agent, wherein the surfactant is responsible for reducing the surface tension of water and emulsifying and decomposing grease stains, enzyme preparations such as protease, lipase and the like are used for decomposing protein, starch intractable stains in a targeted manner, and auxiliary agents such as chelating agents, buffering agents and the like are used for improving the stability of a washing system and the cleaning performance. In recent years, energy-saving low-temperature washing is an industry development trend, and the washing mode can save water resources and energy consumption, can avoid damage of high temperature to clothes materials, and also brings higher technical requirements to the low-temperature decontamination performance of the laundry detergent. The prior laundry detergent still has a plurality of technical pain points in practical application, and is difficult to consider the cleaning performance, enzyme activity stability and environmental compatibility. Firstly, the low-temperature stain removal efficiency is insufficient, the solubility and the diffusion speed of the nonionic surfactant are reduced in a low-temperature environment, the activity of the enzyme preparation is obviously inhibited, the decomposition rate is far lower than that of the enzyme preparation in a warm water condition, so that stubborn stains such as grease, sweat stains and the like are difficult to thoroughly remove, and part of products can remedy the defects by increasing the consumption of the surfactant, so that the system cost is increased, and the system irritation is possibly improved. And meanwhile, the enzyme preparation is denatured and inactivated at high temperature, the activity of the enzyme preparation is limited at low temperature, the stability of the washing performance is seriously influenced by the factors, and the enzyme which is not completely inactivated in part can also cause skin irritation. Thirdly, the fragrance retention and the enzyme system are mutually interfered, the existing fragrance retention scheme mostly adopts a mode of directly adding free essence, the mode is easy to cause volatilization loss of the essence in the storage and washing processes, the essence components are easy to inhibit the enzyme activity, the enzyme effect attenuation is accelerated, and high-efficiency decontamination and long-acting fragrance retention are difficult to realize simultaneously. In addition, the auxiliary agents such as sodium tripolyphosphate and the like commonly used in the traditional liquid laundry detergent are easy to cause water eutrophication, are poor in environmental protection compatibility, and can obviously reduce the action efficiency of the auxiliary agents under the low-temperature condition, and damage clothes or promote the irritation of a system. Disclosure of Invention Aiming at the defects of the prior art, the invention aims to provide a biological compound enzyme-mediated slow-release fragrance-retaining microcapsule laundry detergent for removing stains at low temperature. The biological compound enzyme-mediated low-temperature stain-removing microcapsule slow-release fragrance-retaining laundry detergent comprises, by weight, 8-14 parts of sodium laureth sulfate, 3-6 parts of fatty alcohol polyoxyethylene ether, 4-8 parts of cocamidopropyl betaine, 3-5 parts of sodium citrate, 1-2 parts of tetrasodium glutamate sodium diacetate, 1-1.6 parts of anhydrous sodium carbonate, 2-5 parts of glycerol, 0.2-0.5 part of sodium carboxymethyl cellulose, 0.2-0.6 part of hydroxyethyl cellulose, 0.02-0.05 part of benzisothiazolinone, 3-6 parts of compound enzyme microcapsule slurry and 2-5 parts of sachet microcapsule slurry, and the balance of deionized water, wherein the volume is fixed to 100 parts; Further, the preparation of the complex enzyme microcapsule slu
