    摘要: Fibrous material suitable for incorporation into filter elements of smoking articles such as cigarettes are impregnated with additives and agents such as flavorants, flavorant-enhancers and/or free radical scavengers. The fibrous material is contacted with the additive dispersed in a high pressure gas or supercritical fluid (SCF) held at elevated pressures. The high pressure gas or SCF swells the fibrous matrix and enables the additive to be incorporated within the matrix. When pressure is reduced, the gas or SCF vaporizes and leaves the additive embedded in the fiber interstices. As a result, the additive is slowly released over a finite period of time. When incorporated into a cigarette filter, the additive is released at a desired rate from the interior of the fibrous filter into the cigarette smoke.

    摘要: A smokeless tobacco product includes a plurality of orally disintegrable granules. Each granule has a lipid core and at least one layer surrounding the core. The core can also include binders, powdered tobacco carbohydrates, water soluble polymers, flavorants, salts, sweeteners, and combinations thereof. The orally disintegrable granules can provide a pleasing texture and/or flavor experience.

    摘要: Oral tobacco products having a gel-coating and methods for making are provided. The method includes (a) molding a portion of tobacco material to form a pre-portioned piece of tobacco material, the tobacco material comprising moist smokeless tobacco; (b) contacting the pre-portioned piece of tobacco material with a gel-coating solution to form a gel-coating comprising at least one polymer on an outer surface of the pre-portioned piece of tobacco material to form a gel-coated oral tobacco product, said gel-coating comprising an inner surface disposed around the pre-portioned piece of tobacco material and an outer surface; and (c) forming one or more of perforations, uncoated areas and holes in the gel-coating of the oral tobacco product to form a gel-coated oral tobacco product.

    摘要: The present invention relates to the product(s) of the polymerization of specific combinations of acrylic monomers, and optionally vinyl and/or performance enhancing comonomers, in the presence of an anionic initiator to form copolymers having a narrow molecular weight distribution. Additionally, the invention relates to the use of these copolymers as pour point depressants in lubricating oil formulations.
