Gum base and chewing gum containing same

Claim 1

A single phase formulation for a homogeneous gum base composition containing an elastomer and a resin in the absence of ester gums required to compatibilize said elastomer comprising a plasticized styrene-butadiene elastomer and a plasticized resin, said elastomer being plasticized to make it compatible with other gum base components by adding a plasticizer selected from the group consisting of butyl stearate, butyl oleate, glyceryl trioleate, oleic acid, and mixtures thereof in an amount sufficient to permit formation of the single phase homogeneous admixture, said plasticized resin being plasticized to make it compatible with other gum base components and with said styrene-butadiene elastomer by adding a plasticizer in an amount sufficient to permit formation of the single phase homogeneous admixture.

Claim 25

A method of producing a single phase homogeneous chewing gum base composition in the absence of gum base components other than an elastomer and a resin comprising: plasticizing an elastomer component selected from the group consisting of styrene-butadiene, polyisobutylene and isoprene-isobutylene copolymer sufficiently so that it is compatible with a resin component as well as other gum base ingredients by adding a plasticizer, in the case of styrene-butadiene, selected from the group consisting of butyl stearate, butyl oleate, glyceryl trioleate, oleic acid, and mixtures thereof, and, in the case of polyisobutylene and isoprene-isobutylene copolymer, selected from the group consisting of polylimonene, petrolatum, liquid petroleum hydrocarbons, squalane, squalene, and mineral oil in an amount sufficient to permit the formation of the single phase homogeneous admixture, plasticizing a resin component selected from the group consisting of polyvinyl acetate, polyvinyl butyl ester, copolymers of vinyl esters and vinyl ethers, polyethylene, ethylene-vinyl acetate copolymers, vinyl acetate-vinyl laurate copolymers sufficiently so that it is compatible with an elastomer component by adding a plasticizer selected from the group consisting of glyceryl triacetate, glyceryl tributyrate, diethyl sebacate, acetyl triethyl citrate, ethylacetoacetate, alone or in combination with acetylated monoglyceride in an amount sufficient to permit the formation of the single phase homogeneous admixture, mixing said plasticized components to form a single homogeneous gum base mass, and optionally, adding a third phase of components to said homogeneous mass to again yield a single phase homogeneous gum base mass, which contains desired product characteristics.

Claim 26

A method of producing a single phase homogeneous chewing gum base composition in the absence of gum base components other than an elastomer and a resin comprising: plasticizing an elastomer component selected from the group consisting of styrene-butadiene, polyisobutylene and isoprene-isobutylene copolymer sufficiently so that it is compatible with a resin component as well as other gum base ingredients by adding a plasticizer, in the case of styrene-butadiene, selected from the group consisting of butyl stearate, butyl oleate, glyceryl trioleate, oleic acid, and mixtures thereof, and, in the case of polyisobutylene and isoprene-isobutylene copolymer, selected from the group consisting of polylimonene, petrolatum, liquid petroleum hydrocarbons, squalane, squalene, and mineral oil in an amount sufficient to permit the formation of the single phase homogeneous admixture, plasticizing a resin component selected from the group consisting of polyvinyl acetate, polyvinyl butyl ester, copolymers of vinyl esters and vinyl ethers, polyethylene, ethylene-vinyl acetate copolymers, vinyl acetate-vinyl laurate copolymers sufficiently so that it is compatible with an elastomer component by adding a plasticizer selected from the group consisting of glyceryl triacetate, glyceryl tributyrate, diethyl sebacate, acetyl triethyl citrate, ethylacetoacetate, alone or in combination with acetylated monoglyceride in an amount sufficient to permit the formation of the single phase homogeneous admixture, mixing said plasticized components to form a single homogeneous gum base mass, and optionally, adding a third phase of components to said homogeneous mass to again yield a single phase homogeneous gum base mass, which contains desired product characteristics.
