A pre-vaporization formulation for an e-vaping device includes a vapor former, optionally water, nicotine, nicotine bitartrate and an acid. The pH of the pre-vaporization formulation is between about 4 and about 6. The acid can include one or more of pyruvic acid, formic acid, oxalic acid, glycolic acid, acetic acid, isovaleric acid, valeric acid, propionic acid, octanoic acid, lactic acid, sorbic acid, malic acid, tartaric acid, succinic acid, citric acid, benzoic acid, oleic acid, aconitic acid, butyric acid, cinnamic acid, decanoic acid, 3,7-diemthyl-6-octenoic acid, 1-glutamic acid, heptanoic acid, hexanoic acid, 3-hexenoic acid, trans-2-hexenoic acid, isobutyric acid, lauric acid, 2-methylbutyric acid, 2-methylvaleric acid, myristic acid, nonanoic acid, palmitic acid, 4-pentenoic acid, phenylacetic acid, 3-phenylpropionic acid, hydrochloric acid, phosphoric acid and sulfuric acid.L'invention concerne une formulation de pré-vaporisation d'un dispositif de vapotage électronique (60), la formulation de pré-vaporisation contenant un agent de formation de vapeur, de la nicotine, du bitartrate de nicotine et une combinaison d'une pluralité d'acides. Le pH de ladite formulation de pré-vaporisation est compris entre environ 4 et environ 6. L'invention concerne également un dispositif de vapotage électronique (60) comprenant la formulation de pré-vaporisation.
