Additives for Nicotine Manipulation and Manufacturing
Hundreds of additives are used in making cigarettes. On average they make up about 10% of the weight of the rod. Additives include seam adhesives, glues, branding inks, paper, ash modifiers to control the ash from the burning cigarette rod, humectants to prevent the tobacco from drying out, pH modifiers to alter nicotine absorption and affect the chemosensory properties of the smoke.
