Microcapsule laundry detergent and preparation method thereof

The microcapsule laundry detergent is prepared from the following components in percentage by mass: 0.6 to 3 percent of a suspending agent, 0.5 to 2 percent of a cationic polymer, 15 to 60 percent of a surfactant, 0.05 to 2 percent of microcapsule essence, 0.1 to 15 percent of an auxiliary agent and the balance of water, wherein the suspending agent is bacterial fermentation cellulose; the cationic polymer is chlorinated 2-hydroxy-3-(trimethylamino) propyl polyethylene oxide cellulose ether; and the cationic polymer is a cationic polymer. The surface active agent is selected from at least two of an anionic surface active agent, a nonionic surface active agent and a zwitterionic surface active agent; the molecular weight of the cationic polymer is 1000 to 5000. According to the invention, the microcapsule particles are more stable and uniformly suspended in the system, so that the stability of the product is improved, the appearance of the product is ensured, the deposition amount of the microcapsule essence p
