A tobacco-free oral pouch product providing immediate and long lasting flavor release comprises a pouch wrapper and tobacco-free flavor beads contained within the pouch wrapper. The flavor beads comprise at least one of microcrystalline cellulose, pectin and sodium alginate, at least one polymer having a higher solubility in saliva than microcrystalline cellulose, pectin and/or sodium alginate, and at least one flavorant. The pectin and sodium alginate are cross-linked. The tobacco-free flavor beads provide immediate release of the flavorant upon placement of a pouch product in a user's mouth and long lasting release of the flavorant for about 15 minutes to about 80 minutes. The oral pouch product contains only tobacco-free flavor beads.

Disclosed is a copolymer that includes a repeat unit containing a flavorant-containing pendant and a salt-containing repeating unit. In addition, a comestible, a smoking composition, a smoking article, a smokeless tobacco composition and a heatable or combustible product are provided which incorporate one or more of the flavorant-containing copolymer.

The invention discloses a microencapsulated phase change material having a specific Thermal Efficiency Index (TEI).TEI=&#x3b1;()*&#x3b2;()*&#x3b3;()*&#x3b4;(@180)*&#x2208;()The problem of achieving effective and efficient microencapsulated phase change material can be solved to yield a commercially useful material having the described combination of physical and chemical characteristics based on the parameters described in the specification. Microcapsules according to the invention are highly effective at delivering enhanced thermal performance as compared to conventional microcapsules.

Encapsulates

High strength, high integrity microcapsules containing a hydrophobic core material wherein said microcapsule walls are formed of copolymers of select monomers through a multistep oil-in-water emulsification polymerization process.

High strength microcapsules

The invention teaches a method of efficiently dewatering a microcapsule slurry to form a water re-suspendable filter cake of microcapsules. The process comprises providing an aqueous slurry of microcapsules dispersed in an aqueous solution; adding an agglomeration agent and dispersing the agglomeration agent into the aqueous slurry; adjusting the pH to a pH level sufficient to agglomerate the dispersed microcapsules; and filtering the aqueous slurry of microcapsules by gravity, vacuum or pressure filtration to thereby form a filter cake of dewatered microcapsules. The agglomeration agent is sodium polyphosphate, sodium tetrapolyphosphate, sodium hexametaphosphate, and/or sodium tripolyphosphate; or with anionic microcapsules or coatings even alkaline earth metal salts such as magnesium chloride, calcium chloride or barium chloride, or even aluminum salt such as aluminum chloride.

A scratch-and-sniff coating is provided comprised of a first coating on a substrate having a water- and heat-resistant second coating thereon, the first coating being comprised of a non-encapsulated flavor/fragrance component and a polysaccharide component, and the second coating comprised of a shellac component. The scratch-and-sniff coating is made by forming a first coating comprised of a non-encapsulated flavor/fragrance component and a polysaccharide component and drying the first coating, and forming a water- and heat-resistant shellac-containing second coating on the first coating, and drying the second coating. An encapsulated flavor/fragrance component may optionally be present in the first coating. The scratch-and-sniff coating can be applied to a package for a consumer article.

A smokable composition includes (a) a smokable material; and (b) a supramolecular assembly. The supramolecular assembly comprises a flavorant and at least one selected from the group consisting of O,O'-dibenzoyl-(2R,3R)-tartaric acid, a hydrate thereof or a salt thereof, and ditoluoyl-(2R,3R)-tartaric acid, a hydrate thereof or a salt thereof. In addition, a smoking article comprises a rod of tobacco or tobacco substitute, optionally a filter attached to the rod, and the supramolecular assembly, as menthol-release agent.

Polymers, and particularly conventional commodity bulk polymers, are modified to have a surface activity of interest using a surface modifying polymer that includes a moiety that favors migration to the surface of the bulk polymer together with a moiety provides the activity of interest (e.g., biocidal, wettability modifying (hydrophobic or hydrophilic), resistance to radiant energy, providing a functional group for functionalizing the surface, etc.). The surface modifying polymer is combined with the bulk polymer, and, due to the presence of the moiety that favors migration, concentrates primarily on the surface of the bulk polymer such that the moiety that provides the activity of interest is located primarily on the surface of the bulk polymeric article which is produced. Advantageously, only a minimal amount (such as, e.g., about 2 weight %) of polymeric surface modifier is needed. Being able to achieve desired properties (such as biocidal activity, wettability modification, etc.) without needing much polymeric surface modifier is highly advantageous.
