Abstract
A chewing gum includes a body and a coating. The body includes a gum base polymer, an oil, an active ingredient, an insoluble cellulosic material, and a buffer system. The gum base polymer includes polyvinyl acetate (PVA) in an amount ranging from 35 weight percent to 55 weight percent of the body. The oil includes medium chain triglycerides in an amount ranging from 3 weight percent to 11 weight of the body. The buffer system is present in an amount ranging from 0.1 weight percent to 8 weight percent of the body. The coating is at least partially surrounding the body.
Claims26
A chewing gum comprising:
- a body including,
- a gum base polymer including,
- polyvinyl acetate (PVA) in an amount ranging from 35 weight percent to 55 weight percent of the body,
- oil, the oil including medium chain triglycerides in an amount ranging from 3 weight percent to 11 weight of the body,
- an active ingredient,
- an insoluble cellulosic material, and
- a buffer system in an amount ranging from 0.1 weight percent to 8 weight percent of the body;
- and
- a coating at least partially surrounding the body.
A chewing gum comprising:
- a body including,
- a gum base polymer in an amount ranging from 35 weight percent to 55 weight percent of the body, the gum base polymer including,
- a first polyvinyl acetate (PVA) having a weight average first molecular weight, and
- a second PVA having a second weight average molecular weight different than the first weight average molecular weight,
- a liquid mixture including,
- medium chain triglycerides (MCT) in an amount ranging from 3 weight percent to 11 weight of the body, and
- liquid nicotine dissolved in the MCT,
- microcrystalline cellulose (MCC), at least a portion of the liquid mixture adsorbed on the MCC, absorbed in the MCC, or both adsorbed and absorbed in the MCC,
- sodium carbonate, and
- sodium bicarbonate;
- and
- a coating at least partially surrounding the body.
A method of making a chewing gum comprising:
- preparing a diluted nicotine by dissolving liquid nicotine in an oil;
- preparing a cellulose admixture by adsorbing the diluted nicotine on, absorbing the diluted nicotine in, or both adsorbing the diluted nicotine on and absorbing the diluted nicotine in a cellulosic material;
- preparing a gum base including a gum base polymer and the cellulose admixture, the gum base polymer including polyvinyl acetate;
- preparing a chewing gum core including the gum base;
- and
- preparing the chewing gum by coating the chewing gum core.
