The invention discloses an easy-to-wash active printing thickener. The easy-to-wash active printing thickener comprises the following raw material components in parts by weight (100 parts in total): 44-80 parts of a thickening component, 4-20 parts of a washing component, 1-5 parts of a stabilizer component, 2-30 parts of a filling component and 0.1-1 part of a wetting component, wherein the washing component is selected one or more of polyvinylpyrrolidone, sodium dodecyl sulfate, beta-cyclodextrin, methyl-beta-cyclodextrin, 2,6-dimethyl-beta-cyclodextrin, sodium metasilicate pentahydrate, sodium bicarbonate and trisodium phosphate. The active printing thickener has the advantages that the raw material components is wide in source, can dispense with sodium alginate and is relatively low in cost, and on the premise of meeting the printing demand, washing and paste removal are easy, the hand feeling is soft, the stability is good, the comprehensive performance is quite the same as sodium alginate, the cost is relatively low, and a wide application value is achieved.
