A solvent for aerosol-generating material includes predominantly 1, 3-Propanediol and glycerol, wherein the 1, 3-Propanediol is less than 50% by weight based on the total weight of the solvent. In particular, it is shown also herein that when the ratio of 1, 3-Propanediol to glycerol is 3:7, the solvent significantly improves for example thermal stability as well as decreases inhaled flavours concentrations.
