The invention discloses a hyperconcentration anhydrous laundry detergent as well as a preparation method and laundry beads thereof. The hyperconcentration anhydrous laundry detergent comprises the following components in parts by mass: 1 part of cardanol polyoxyethylene ether, 0.2-1.0 part of coconut diethanol amide, 0.2-1.0 part of AES, 0.2-1.0 part of AEO-10 and 1.0-2.0 parts of polyethylene glycol. In the invention, the cardanol polyoxyethylene ether, coconut diethanol amide, AES and AEO-10 are used as main active ingredients, and the surfactants have good compatibility; meanwhile, by adopting the polyethylene glycol with washing performance as a solvent, the washing performance of the hyperconcentration anhydrous laundry detergent is further improved; the adopted surfactants are plant-based green surfactants or polyether natural product derivatives which are nontoxic to human and livestock and pollution-free to the environment and have good biological compatibility; moreover, the hyperconcentration anhydrous laundry detergent is easy to transport and store, and the transport cost is greatly reduced.
