The first fragrance, fabric softening agent, and coating agent can be coated onto the particulate core to form the particulate fragrance enhancer. ## Claims ### Claim 1 A particulate fragrance enhancer, comprising: a first fragrance; an esterquat, cationic polysaccharide, or imidazolium fabric softening agent; a water-soluble coating agent, said water-soluble coating agent being a liquid at a temperature of from about 68° F. to about 72° F.; and a particulate core, wherein the first fragrance, the fabric softening agent, and the water-soluble coating agent are combined in a premix prior to being coated onto the particulate core, wherein the first fragrance, the fabric softening agent, and the water-soluble coating agent are coated onto the particulate core at the same time. ### Claim 2 (depends on 1) The particulate fragrance enhancer of claim 1, wherein the first fragrance is present in the particulate fragrance enhancer in an amount from about 0.1 wt % to about 6 wt %. ### Claim 3 (depends on 1) The particulate fragrance enhancer of claim 1, wherein the fabric softening agent is present in the particulate fragrance enhancer in an amount from about 0.1 wt % to about 10 wt %. ### Claim 4 (depends on 1) The particulate fragrance enhancer of claim 1, wherein the fabric softening agent has a melting point of less than or equal to 68° F. ### Claim 5 (depends on 1) The particulate fragrance enhancer of claim 1, wherein the fabric softening agent comprises a compound having a structure according to Formula I: where R and R′ are independently selected from a methyl, ethyl, or propyl group, R1 and R2 are independently selected from a saturated or unsaturated C14-C20 alkyl group, R3 is selected from a methyl, ethyl, or propyl group, R4 is selected from hydroxymethyl, hydroxyethyl, or hydroxypropyl groups, and A− is selected from a halide, sulfate, methyl sulfate, or ethyl sulfate. ### Claim 6 (depends on 1) The particulate fragrance enhancer of claim 1, wherein the fabric softening agent comprises a compound having a structure according to Formula II: where R5, R6, and R7 are independently selected from: hydrogen (H), a linear or branched, substituted or unsubstituted C1-C24 alkyl group, or a group having a structure according to Formula III: where n is an integer from 0 to 10, R9 is selected from H or a substituted or unsubstituted C1-C6 alkyl group, and Rx is H, a linear or branched, substituted or unsubstituted C1-C24 alkyl group, or a group having a structure according to Formula IV: where Z is a water soluble anion selected from a halide, hydroxide, phosphate, sulfate, methyl sulfate, ethyl sulfate, or acetate, and R10, R11, R12 are independently selected from H, a linear or branched, substituted or unsubstituted C1-C28 alkyl group, a benzyl group, or a substituted benzyl group, and R8 is H, —(P)m-H, or a combination thereof, where P is a repeat unit of an addition polymer formed by a cationic monomer selected from methacrylamidotrimethylammonium chloride, a dimethyl diallyl ammonium having a structure according to Formula V: or combinations thereof, and m is an integer from 1 to 100. ### Claim 7 (depends on 1) The particulate fragrance enhancer of claim 1, wherein the water-soluble coating agent is present in the particulate fragrance enhancer in an amount from about 0.001 wt % to about 2 wt %. ### Claim 8 (depends on 1) The particulate fragrance enhancer of claim 1, wherein the particulate core is present in the particulate fragrance enhancer in an amount from about 70 wt % to about 99 wt %. ### Claim 9 (depends on 1) The particulate fragrance enhancer of claim 1, wherein the particulate core has a particle size of from about 0.5 mm to about 5 mm. ### Claim 10 (depends on 1) The particulate fragrance enhancer of claim 1, further comprising a second fragrance coated over the particulate core having the first fragrance, the fabric softening agent, and the water-soluble coating agent coated onto it, said second fragrance being an encapsulated fragrance. ### Claim 11 (depends on 10) The particulate fragrance enhancer of claim 10, wherein the first fragrance and the second fragrance are present at weight ratio of from about 1:4 to about 3:1. ### Claim 12 (depends on 10) The particulate fragrance enhancer of claim 10, wherein the second fragrance has a particle size of from about 10 microns to about 180 microns. ### Claim 13 A method of manufacturing a particulate fragrance enhancer, comprising: combining a first fragrance, a fabric softening agent, and a water-soluble coating agent in a premix, wherein the water-soluble coating agent is a liquid at a temperature of from about 68° F. to about 72° F.; and coating a particulate core with the premix of the first fragrance, the fabric softening agent, and the water-soluble coating agent in a mixing vessel to form the particulate fragrance enhancer. ### Claim 14 (depends on 13) The method of claim 13, wherein the coating comprises spraying the water-soluble coating agent, the first fragrance, the fabric softening agent, or a combination thereof onto the particulate core. ### Claim 15 (depends on 13) The method of claim 13, wherein the coating further comprises applying a corrosion inhibitor, a processing aid, or a combination thereof to the particulate core in the mixing vessel to form the particulate fragrance enhancer. ### Claim 16 (depends on 13) The method of claim 13, wherein the mixing vessel is a member selected from the group consisting of: a plow mixer, a ribbon mixer, a spiral mixer, a paddle mixer, a v-blender, a conical screw mixer, and a drum mixer. ### Claim 17 (depends on 13) The method of claim 13, further comprising applying a second fragrance onto the coated particulate core to form the particulate fragrance enhancer, said second fragrance being an encapsulated fragrance. ### Claim 18 (depends on 17) The method of claim 17, wherein the applying is performed by adding the second fragrance to the coated particulate core on a conveyor via a vibratory feeder. ### Claim 19 (depends on 17) The method of claim 17, wherein the applying is performed by combining the second fragrance and the coated particulate core in a conical mixer. ### Claim 20 (depends on 13) The method of claim 13, wherein the fabric softening agent is an esterquat, cationic polysaccharide, or imidazolium.
