Abstract: The present invention relates to chewing gum compositions whose elastomeric component in the chewing gum base employed in formulating said chewing gum compositions comprises as an essential ingredient a polyisoprene obtained from naturally-occurring guayule rubber.

Abstract: A cleansing composition is disclosed that is particularly suited for compaction into tablet form, and comprises a phosphate salt, an optionally added silicate salt, such as a metasilicate and at least one perborate salt, wherein at least a portion of the perborate salt component is present as a compacted, granulated mixture with from about 0.01% to about 0.70% by weight of the perborate salt, of a polymeric fluorocarbon. Preferably, the perborate salt includes sodium perborate monohydrate and anhydrous sodium perborate, and polytetrafluoroethylene comprises the polymeric fluorocarbon used to prepare the granules.When present, the silicate salt is preferably utilized within a particle size ranging from about 1 to about 25 microns. The silicate aids disintegration and assists in mechanical cleaning, when the composition is prepared in tablet form for use as a denture cleanser.

Abstract: A method is disclosed for the preparation of granulated perborate salts having improved utility in compressible compositions such as those formed into denture cleanser tablets. The method broadly comprises forming a mixture of one or more perborate salts such as sodium perborate monohydrate and anhydrous sodium perborate, with a polymeric fluorocarbon such as polytetrafluoroethylene, with the polytetrafluoroethylene present in an amount ranging from about 0.01% to about 0.70% by weight of the perborate salt. The particles thus prepared exhibit combination of improved hardness and specific weight that facilitates their participation in the compressible cleanser composition, together with enhanced disintegration characteristics that are favorably imparted to the cleanser tablets.The present invention also includes the granular salts prepared by the method, which have a broad range of utility in detergents, cleansers and the like.

Abstract: A method for the preparation of benzoyl peroxide in crystalline form, which crystals may range in size below 10 microns, comprises forming a first solution of the benzoyl peroxide in a precipitate promoting material, adding the first solution to a second solution comprising an aqueous solution of a dispersant, to precipitate the benzoyl peroxide in the desired crystalline form, and finally recovering the crystalline benzoyl peroxide from the first and second solutions. The precipitate promoting material may be selected from sulfur-containing aliphatic ethers, long-chain aliphatic and araliphatic ethers, ethylene oxide derivatives, and mixtures thereof. The dispersant may be selected from cellulosic derivatives, anionic surfactants, nonionic surfactants, colloidal inorganic materials, and mixtures thereof. The present method may be performed at room temperature and is therefore safe and energy conservative.

Abstract: A flavor composite comprises a mixture of sorbitol, mannitol, saccharin, and a flavor material contained therein. Preferably, the saccharin is present in an amount of 3% by weight of the mannitol. The presence of mannitol and saccharin is theorized to lower the congealing temperature of sorbitol, so that volatile flavors may be incorporated therein with minimal flavor loss.The present flavor composite may be prepared in the form of sugar-free candies, or may be reduced to particles or beads, having particle sizes appropriate for incorporation into comestible products such as chewing gums.A method of preparing the flavor composites is also disclosed, which utilizes seed particles containing sorbitol, added to the mixture after the flavor to assist in the commencement of hardening.

Abstract: A non-adhesive chewing gum base composition demonstrates reduced adhesion, and improved chewing satisfaction, and consists essentially of an elastomer, at least one emulsifier including lecithin, lecithin derivatives, or mixtures thereof in an amount of from 0.5% to 6.0%, an elastomer solvent including the glyceryl ester of partially hydrogenated wood rosin, the latter present in an amount of from about 2.5% to about 8%, as well as one or more mineral adjuvants, a non-toxic vinyl polymer and at least one oleaginous plasticizer. Preferably, the wood rosin elastomer solvent is present in an amount ranging from 2.5 to 5%.A method for preparing the present chewing gum base composition is also disclosed, which comprises mixing the ingredients of the base composition in one step. Preferably, the elastomer is charged first, and subject to high shear, after which the remaining components are added and shearing is continued.

Abstract: Curable acrylate ester compositions having as an accelerator for the polymerization a hydrazine derivative of the formula R.sup.1 --HN--NH--CO--R.sup.2. Typical of the monomers are the polyalkyleneglycol dimethacrylates and the so-called urethane acrylates. Polymerization is preferably initiated by a peroxy compound such as cumene hydroperoxide, such a composition having anaerobic curing characteristics.

Abstract: A polymerizable adhesive and sealant composition comprising a urethane-acrylate-capped prepolymer based on a polybutadiene polyol or polyamine having at least about 70 percent of the butadiene units in the 1,4-configuration. The composition provides improved thermal, impact and cure-through-gap properties. A process for preparing the composition and a process for using it are also disclosed.
