The invention provides certain nicotine salts, co-crystals, and salt co-crystals and provides novel polymorphic forms of certain nicotine salts. In particular, nicotine salts with mucic acid, 3,5-dihydroxybenzoic acid, and 2,3-dihydroxybenzoic acid, and crystalline polymorphic forms of nicotine 4-acetamidobenzoate, nicotine gentisate, and nicotine 1-hydroxy-2-naphthoate are described. The invention further provides methods of preparation and characterization of such nicotine salts, co-crystals, and salt co-crystals and polymorphic forms thereof. In addition, tobacco products, including smoking articles, smokeless tobacco products, and electronic smoking articles comprising nicotine salts, co-crystals, and/or salt co-crystals are also provided.

An synthetic fiber oral flavored product includes a fibrous substrate. The fibrous substrate is made of a synthetic polyester in a typically pelletized shape imbued a carrier liquid of propylene glycol or equivalent. The carrier liquid carries a freebase synthetic nicotine, a binding agent, a textural adjustment agent and flavorants. In some examples, the fibrous substrate is heat treated and modified by heating and rapid cooling the substrate to increase the zeta potential of the fibrous substrate.

A composition is provided, the composition including a binder system in an amount of at least about 5% by weight, based on the total weight of the composition, and at least one active ingredient and/or flavoring agent. The binder system includes at least one thermoplastic binding material and at least one plasticizer. The composition is typically substantially free of unbleached tobacco material, excluding any nicotine component present.

The disclosure provides compositions and products configured for oral use. For example, a composition is provided that includes a foam containing a lipid and an active agent and/or a flavorant, and a carrier, wherein the foam is adsorbed onto the carrier. Such a foam can be incorporated, e.g., within lozenges and/or pouched oral products. The disclosure further provides an oral product (e.g., a lozenge and/or pouched oral product) including an encapsulated agent, wherein the encapsulated agent is a porous bead with an exterior portion and an interior portion containing a lipid and an active agent and/or a flavorant.

Compositions configured for oral use, the compositions including at least one active ingredient selected from caffeine, taurine, GABA, theanine, tryptophan, vitamin B6, vitamin B12, vitamin C, lemon balm extract, ginseng, citicoline, sunflower lecithin, or combinations thereof, are provided. The compositions include one or more fillers, including a sugar alcohol, and optionally, a lipid or binder. The compositions may be in chewable, tablet, or meltable forms.

Exemplary embodiments contained herein relate to smokeless products containing one or more non-tobacco plant materials and methods of manufacture thereof. Exemplary embodiments are related to the method of manufacture of various chew products containing non-tobacco ingredients including plant material and a starch, a sweetener, natural and artificial flavors, a pH adjuster, solvent, salt, and liquid synthetic nicotine and methods of manufacture thereof. The liquid synthetic nicotine is provided at greater volumes compared to when liquid tobacco-derived nicotine is used due to the presence of both R nicotine isomers and S nicotine isomers present in the liquid synthetic nicotine.

The present disclosure relates to an oral pouched nicotine product comprising a moist filling material and a saliva-permeable pouch of a packaging material enclosing the moist filling material, wherein the moist filling material comprises a particulate non-tobacco material; a non-encapsulated non-particulate flavouring agent; a nicotine source; a pH adjusting agent; a monoglyceride; and tobacco material within the range of from 0% to % by weight, based on the total weight of the moist filling material.

The present disclosure provides an environment-friendly wrapping-free heat-not-burn naked tobacco product. The tobacco product includes, in percentage by mass, 20-60% of mixed powder, 10-40% of a porous carrier material, 15-50% of a tobacco extraction mixture, 1-10% of a particle aggregation inhibitor and 10-40% of a binder. The environment-friendly wrapping-free heat-not-burn naked tobacco product can effectively inhibit emission of harmful substances in smoke; meanwhile, a paper tube, a filter tip and a blocking piece which are required for a traditional cigarette are not needed, the naked tobacco product is utilized, the difficulty of a production process is lowered, raw materials are reduced, and the tobacco product is more environmentally friendly. According to the tobacco product with the proportion of components, the smoke amount is abundant, the fragrance is good, smoke is soft and fine, offensive firewood smell is avoided, irritation is small, the remaining taste makes people comfortable.
