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.

2. 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 %.

3. 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 %.

4. The particulate fragrance enhancer of claim 1 , wherein the fabric softening agent has a melting point of less than or equal to 68° F.

5. 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 C 14 -C 20 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.

6. The particulate fragrance enhancer of claim 1 , wherein the fabric softening agent comprises a compound having a structure according to Formula II:

where R 5 , R 6 , and R 7 are independently selected from:

hydrogen (H),

a linear or branched, substituted or unsubstituted C 1 -C 24 alkyl group, or

a group having a structure according to Formula III:

where n is an integer from 0 to 10,

R 9 is selected from H or a substituted or unsubstituted C 1 -C 6 alkyl group, and

Rx is H, a linear or branched, substituted or unsubstituted C 1 -C 24 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

R 10 , R 11 , R 12 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.

7. 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 %.

8. 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 %.

9. 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.

10. 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.

11. 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.

12. The particulate fragrance enhancer of claim 10 , wherein the second fragrance has a particle size of from about 10 microns to about 180 microns.

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.

14. 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.

15. 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.

16. 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.

17. 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.

18. 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.

19. The method of claim 17 , wherein the applying is performed by combining the second fragrance and the coated particulate core in a conical mixer.

20. The method of claim 13 , wherein the fabric softening agent is an esterquat, cationic polysaccharide, or imidazolium.
