Abstract
Compositions are provided which contain immobilized flavorants for flavor delivery. In particular, smoking compositions are provided which contain flavorant ester salts of polycarboxylic acids.
Claims5
A smoking composition comprising a mixture of smokable material and an ester containing an alcohol moiety that is a flavorant and an acid moiety that is a polycarboxylic acid, wherein at least one of the carboxyl groups of the polycarboxylic acid is in the form of a metal salt, wherein there is at least one carbon atom between the carbonyl carbon of the ester and the carboxyl carbon forming the salt and wherein the smokable composition is in the form of a rod, wherein the polycarboxylic acid is selected from the group consisting of malonic acid, succinic acid, glutaric acid and adipic acid, and wherein the flavorant is selected from the group consisting of menthol, vanillin, linalool, guaicol, thymol, geraniol and eugenol.
