Description
NON-STICKY MASK RUBBER BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to a non-tacky chewing gum base composition that is free from fats, waxes and elastomer plasticizing materials known as elastomer solvent resins and a rubber composition. chewing prepared using the gum base.
Description of the Prior Art Chewing gums are conventionally prepared by adding sweeteners, flavoring agents and the like to a chewing gum base. Conventional chewing gum bases typically contain, as a main ingredient, any of a number of different resinous gum materials such as: (1) natural rubber elastomers (e.g., rubber latex, guajle and the like); (2) natural rubber elastomers (for example, chewing gum, jelutong, balata, gutta-percha, lechi caspi, sorva, pendare, perillo, cow's milk, niger gutta, tunu, chiquibul, rubber crown and the like); (3) synthetic rubber elastomers (e.g., styrene-butadiene rubber, polyisobutylene, isobutylene-isoprene copolymers, polybutadiene and the like); (4) synthetic hydrophobic polymers (eg, polyvinyl acetates, ethylene / vinyl acetate, vinyl laurate / vinyl acetate copolymer and the like); (5) mixtures thereof. Other functional ingredients are typically present in conventional chewing gum bases to modify and customize the total properties of the resulting chewing gum, such as one or more fats, waxes, elastomer solvent resins, fillers, softeners, emulsifiers, plasticizers, antioxidants, etc. The particular combination of ingredients used in a chewing gum base depends on factors such as the particular type and amount of resinous gum material employed and the general texture and consistency characteristics desired of the resulting chewing gum composition (e.g., chewing, stickiness, flavor release, elasticity, characteristic of film formation, elasticity, etc.).
Fats, waxes and solvent resins elastomers help to soften and plasticize the resinous rubber material and also provide other desirable properties. For example, fats provide softness to chewing gum, waxes improve the elasticity of their chewing character, and solvent resins elastomers provide chewing volume. However, fats, waxes and solvent-based elastomeric resins also adversely affect the characteristics of chewing gum; for example, they result in greater stickiness and reduced flavor release. For example, fats such as hydrogenated or partially hydrogenated vegetable oils including cottonseed and soybean oils, hydrogenated or partially hydrogenated animal fats, cocoa butter and the like reduce the viscosity of the gum base, which causes It becomes sticky. Waxes such as paraffin wax, microcrystalline wax, petrolatum wax, natural waxes and the like also result in higher tack. The elastomeric solvent resins used as softeners and tackifiers for the resinous rubber material, such as esters of methyl, glycerol and pentaerythritol of modified rosins or rosins, including hydrogenated, dimerized or modified rosins, terpene resins including polyterpene and polymers of alpha- pinene or beta-pinene and the like, also contribute to stickiness. As a result, conventional chewing gums have been criticized by some who believe that gums that have been consumed and disposed of improperly contaminate the environment by sticking to surfaces on which they have been deposited.
Because conventional chewing gums adhere strongly to a variety of surfaces including wood, floors, asphalt, pavement, concrete, carpets, skin, hair and fabrics, the discarded chewing gums that stick to those surfaces are often difficult and expensive to remove. ContinuedEven after removing the chewing gums, there are spots on the surfaces. As a result, vendors have been prohibited from selling conventional chewing gums to consumers in many public places such as train stations, stadiums, amusement parks and schools. The country of Singapore has flatly prohibited the sale of chewing gums. Accordingly, a chewing gum that is easily removed from the surfaces on which it is discarded or deposited would be highly desirable.
Conventional chewing gums that have non-tacky characteristics are typically designed not to adhere to natural teeth and synthetic dental products during chewing. These chewing gums, however, still adhere to other surfaces when they are discarded. For example, U.S. Patent Nos. 3,984,574, 4,357,355, 4,518,615 and 5,266,336 have non-tacky chewing gum compositions that do not adhere to dentures, amalgams or natural teeth, but still stick to other surfaces.
U.S. Patent Nos. 4,794,003 and 4,721,620 have rubber compositions for making pumps that do not stick to the face. These compositions, however, contain fats, waxes solvent resins elastomers.
U.S. Patent No. 5,116,626 presents a transparent chewing gum base composition containing a variety of ingredients such as elastomers of synthetic gums, polyvinyl acetates, softeners and fillers and optionally fats, waxes and elastomer solvent resins.

The amounts of the different polyvinyl acetates of different molecular weights present in the gum base composition should be effective in providing the finished chewing gum with the desired non-tackiness and chewing properties., such as integrity, smoothness, chewing volume, characteristic of film formation, hydrophilic character and flavor release. The total amount of polyvinyl acetate used in the gum base composition is usually from about 45% to about 92% by weight based on the total gum base composition. It is preferred to use an amount of polyvinyl acetate from about 60% to about 85%, especially about 75% by weight of the total gum base composition.
Normally, low molecular weight polyvinyl acetate has an average molecular weight of from about 2,000 to 14,000 and preferably from about 11,000 to about 13,000. The amount of the low molecular weight polyvinyl acetate used in the gum base composition is usually from about 39% to about 75%, preferably from about 40% to about 50% and more preferably about 44% by weight in weight. based on the total weight of the gum base composition.
Normally, the polyvinyl acetate of average molecular weight has an average molecular weight of from about 15,000 to 55,000 and preferably from about 45,000 to about 55,000. Medium molecular weight polyvinyl acetate is typically employed in the gum base composition in an amount of from about 5% to about 41%, preferably from about 20% to about 40% and more preferably about 32% by weight based on the total weight of the gum base composition.
The high molecular weight polyvinyl acetate has an average molecular weight from about 56,000 to about 500,000. The high molecular weight polyvinyl acetate is usually employed in the gum base composition in an amount of up to about 10% and preferably up to about 5%. The average molecular weight can be determined by conventional methods such as gel permeation chromatography.
Preferably, at least one other resinous gum material is employed in the gum base composition of this invention. The amount of said additional resinous gum material present should be effective to provide a finished chewing gum with the chewing volume, elasticity, flavor release, desired film-forming characteristic. Typically the additional resinous rubber material is present in an amount of up to about 10% and preferably from about 5% to about 10% and more preferably about 8% by weight based on the total weight of the base composition of rubber.

The manner in which the components of the gum base composition are mixed is not critical and can be carried out using standard techniques and equipment known to those skilled in the art. Typically, any additional resinous rubber material, such as a rubber elastomer, is stirred in a mixing pot until a homogeneous mixture is obtained. The filler is then added to the mixture. The polyvinyl acetate components are then added to the mixture. It is preferred that the high molecular weight polyvinyl acetate be added and mixed first followed by the medium molecular weight one and then the low molecular weight polyvinyl acetate. In this way, a uniform mix can be achieved without the creation of polyvinyl acetate insulated bags in the elastomer. If no resinous rubber material is used in the gum base composition the polyvinyl acetate is mixed as described and the filler is then mixed into the polyvinyl acetate. The remaining ingredients can then be added fully, incrementally or stepwise while mixing until a homogeneous mass is obtained.
