         4 . The electronic cigarette liquid according to  claim 1 , characterized in that the composition contains, in addition, propylene glycol. 
     
     
         5 . The electronic cigarette liquid according to  claim 4 , characterized in that the propylene glycol is obtained from plant raw materials. 
     
     
         6 . The electronic cigarette liquid according to  claim 1 , characterized in that the 1,3-propanediol is obtained from plant raw materials. 
     
     
         7 . Liquid composition for an electronic cigarette including 1,3-propanediol as well as at least one compound selected from: nicotine, a nicotine substitute, and an aroma. 
     
     
         8 . Composition according to  claim 7 , characterized in that it is free of glycerol. 
     
     
         9 . Composition according to  claim 7 , characterized in that it contains, in addition, propylene glycol, preferably of plant origin. 
     
     
         10 . Composition according to  claim 7 , characterized in that the 1,3-propanediol is obtained from plant raw materials. 
     
     
         11 . Composition according to  claim 7 , characterized in that it contains no water and/or ethanol. 
     
     
         12 . Composition according to  claim 7 , characterized in that it has a kinematic viscosity at 20° C. of less than 200 mPas·s, preferably less than 100 mPa·s, more preferably less than 75 mPa·s, and better yet less than 60 mPa·s, said viscosity being greater than 30 mPa·s, preferably greater than 40 mPa·s, and better yet greater than 50 mPa·s. 
     
     
         13 . Electronic cigarette containing a composition according to  claim 7 . 
     
     
         14 . A method of improving the throat hit felt by a user of an electronic cigarette liquid and/or the ease of inhaling the vapor produced by an electronic cigarette liquid, comprising adding 1,3-propanediol in an electronic cigarette liquid which may or may not contain nicotine. 
     
     
         15 . A method of reinforcing the aromatic power in an electronic cigarette liquid, comprising adding 1,3-propanediol, optionally in the presence of glycerol, to an electronic cigarette liquid. 
     
     
         16 . A method of limiting or eliminating the formation of coproducts of thermolysis in an electronic cigarette liquid, comprising adding 1,3-propanediol, optionally in the presence of glycerol, to an electronic cigarette liquid. 
     
     
         17 . A method of improving the bioavailability of the nicotine in an electronic cigarette liquid containing nicotine, comprising adding 1,3-propanediol to an electronic cigarette liquid containing nicotine.
