Electronic cigarette atomizing agent

The invention belongs to the technical field of electronic cigarette liquid preparation, and particularly relates to an electronic cigarette atomizing agent which comprises ester compound, water, propylene glycol and/or glycerol. The ester compound is one of unitary ester compound, binary ester compound and ternary ester compound and a mixture of the same according to any proportion. Unique taste characteristics of high-molecular-weight esters are utilized, combining ratios of the esters are screened and optimized, the esters are used as the electronic cigarette atomizing agent, and the electronic cigarette atomizing agent can be used solely and can be matched with existing atomizing agents for use. Experiments on evaluating suction show that the electronic cigarette atomizing agent is good in taste, sweetness and greasiness caused by the fact that the existing atomizing agents use a lot of glycerol and propylene glycol can be overcome remarkably, suction taste of electronic cigarettes is improved and is close to that of conventional cigarettes, and popularization and use of the electronic cigarettes are facilitated.
