The invention relates to the technical field of laundry detergents, and particularly discloses a concentrated laundry detergent capable of stably dispersing microcapsule essence and a preparation method of the concentrated laundry detergent. An organic polyurethane compound with a specific carbamate structure (the general formula is RNHCOOR ') is adopted as a suspending agent, the compound constructs a three-dimensional network structure through intermolecular hydrogen-bond interaction, the hydrogen bond donor / acceptor density of a carbamate unit is higher than that of existing suspension systems such as polyamide and hydrogenated castor oil, and the system is endowed with remarkable thixotropic characteristics. Under the action of shearing force, the network is dissociated, and the viscosity is reduced; and after the shearing force is removed, the hydrogen bond is quickly reconstructed, the viscosity rises again, rheological yield stress is generated, and stable anchoring of the high-load suspended matter is achieved. Meanwhile, due to the characteristic of high melting point of the organic polyurethane compound, the high-temperature processing condition can be tolerated, and the phenomenon of hot roughing is avoided. In addition, the hydrolysis resistance of the carbamate bond ensures the long-term stability of the suspension system in an environment with pH of 6-10 and in the presence of lipase.
