1. A method of enhancing adherence of a fragrance composition to a substrate, comprising: coating the fragrance composition with a polymer selected from the group consisting of a Type-1 Polymer, a Type-2 Polymer, and a mixture thereof, to form an adherent fragrance composition, and;contacting the substrate with the adherent fragrance composition;wherein the fragrance composition comprises a fragrance particulate and a viscoelastic gel, and the fragrance particulate comprises a fragrance and is coated with the viscoelastic gel,wherein the viscoelastic gel comprises κ-carrageenan,wherein the Type-1 Polymer has a cationic nitrogen content of at least about 3 wt. % and a weight average molecular weight of less than about 800,000 Dalton, and is selected from the group consisting of poly(diallyldimethyl ammonium halide), poly(DADMAC), and combinations thereof, andwherein the Type-2 Polymer has a cationic nitrogen content of less than about 3 wt. % and a weight average molecular weight of greater than about 1,000,000 Dalton, and is selected from the consisting of a cationic guar gum, a cationic cellulose, a cationic starch, hydrophobically-modified versions thereof, and combinations thereof. 2. The method of claim 1, wherein the substrate is selected from the group consisting of teeth, hair, skin, fabric, plastic, polymer, glass, stone, metal, insects, plants, fungus, yeast, foods, and mixtures thereof. 3. The method of claim 2, wherein the composition contacts the fabric with water during washing of the fabric. 4. A fragrant substrate comprising: a substrate;an adherent fragrance composition disposed on the substrate, the adherent fragrance composition comprising:a fragrance composition comprising a fragrance particulate and a viscoelastic gel, wherein the fragrance particulate comprises a fragrance and is coated with the viscoelastic gel, and the viscoelastic gel comprises κ-carrageenan; anda polymer coating the fragrance composition, the polymer being selected from the group consisting of a Type-1 Polymer, a Type-2 Polymer, and a mixture thereof, wherein:the Type-1 Polymer has a cationic nitrogen content of at least about 3 wt. % and a weight average molecular weight of less than about 800,000 Dalton, and is selected from the group consisting of poly(diallyldimethyl ammonium halide), poly(DADMAC), and combinations thereof, andthe Type-2 Polymer has a cationic nitrogen content of less than about 3 wt. % and a weight average molecular weight of greater than about 1,000,000 Dalton, and is selected from the consisting of a cationic guar gum, a cationic cellulose, a cationic starch, hydrophobically-modified versions thereof, and combinations thereof. 5. The fragrant substrate of claim 4, wherein the substrate is selected from the group consisting of hair, skin, fabric, plastic, polymer, glass, stone, metal, insects, plants, fungus, yeast, and mixtures thereof. 6. The fragrant substrate of claim 5, wherein the substrate is a fabric.
