Composition for electronic cigarettes
The present invention relates to a new vegetable-based composition for liquid to be vaporized in electronic cigarettes, comprising water and propylene glycol of vegetable origin and/or glycerol and/or nicotine and/or natural flavors.
1. A process for the manufacture of liquid composition for electronic cigarettes comprising at least water, propylene glycol of vegetable origin and glycerol, said process comprising:
forming said propylene glycol by milling maize to provide starch and other products, reacting said starch via enzymatic saccharification to provide glucose, converting said glucose to sorbitol by catalytic hydrogenation, converting said sorbitol to said propylene glycol by catalytic hydrogenation, and extracting and purifying said propylene glycol,
deriving said glycerol from palm oil and/or coconut oil to form glycerol of food grade vegetable origin,
providing water, and
combining at least said water, said propylene glycol of vegetable origin and said glycerol.
2. The process according to claim 1 , wherein the liquid composition further comprises nicotine and natural flavors.
3. The process according to claim 1 , wherein said propylene glycol is characterized by a spectra exhibiting a peak that indicates 2,3-butanediol.
4. The process according to claim 2 , further comprising providing the liquid composition to an electronic cigarette cartridge to be vaporized.
5. A process for the manufacture of a composition for liquids for electronic cigarettes comprising water, propylene glycol of vegetable origin, glycerol, nicotine and natural flavors, said process comprising:
forming said propylene glycol by milling maize to provide starch and other products, reacting said starch via enzymatic saccharification to provide glucose, converting said glucose to sorbitol by catalytic hydrogenation, converting said sorbitol to said propylene glycol by catalytic hydrogenation, and extracting and purifying said propylene glycol,
deriving said glycerol from palm oil and/or coconut oil to form glycerol of food grade vegetable origin,
providing water, food grade ethyl alcohol and bergamot natural flavor; and
combining said water, said propylene glycol of vegetable origin, said glycerol, said food grade ethyl alcohol, said bergamot natural flavor and nicotine.
