Abstract

A method of providing a longer lasting fragrance and a kit for delivering a longer lasting fragrance by dispensing microcapsules and a volatile solvent is provided.

First claim

What is claimed is:

1. A method of providing a longer lasting fragrance, the method comprising:
spraying a first composition onto a situs, the first composition comprising a volatile solvent and a first fragrance; and
spraying a second composition onto the situs, the second composition comprising a carrier and a plurality of microcapsules;
wherein the first composition differs from the second composition in chemical makeup; and
wherein said first and second compositions are stored in different dispensers and provided as a kit, said kit having written instructions instructing a user to apply said first and second compositions sequentially.

2. The method according to claim 1 , wherein the second composition further comprises a second fragrance that is encapsulated within the microcapsules.

3. The method of claim 1 , wherein the microcapsules comprise a core material and a shell that surrounds said core material.

4. The method of claim 1 , wherein the microcapsules comprise a core material and a shell that surrounds said core material, wherein the shell comprises a material selected from the group consisting of polyacrylates; polyethylenes; polyamides; polystyrenes; polyisoprenes; polycarbonates; polyesters; polyureas; polyurethanes; polyolefins; polysaccharides; epoxy resins; vinyl polymers; urea cross-linked with formaldehyde or gluteraldehyde; melamine cross-linked with formaldehyde; gelatin-polyphosphate coacervates optionally cross-linked with gluteraldehyde; gelatin-gum Arabic coacervates; cross-linked silicone fluids; polyamine reacted with polyisocyanates; acrylate monomers polymerized via free radical polymerization; and naturally occurring polymers selected from the group consisting of silk, wool, gelatine, cellulose, proteins, and combinations thereof.

5. The method of claim 1 , wherein the microcapsules have a median volume-weighted particle size of from about 2 microns to about 80 microns.

6. The method of claim 1 , wherein the volatile solvent comprises ethanol.

7. The method of claim 1 , wherein the first composition comprises 0.01% to 98%, by weight, of ethanol, as the volatile solvent.

8. The method of claim 1 , wherein the carrier comprises water.

9. The method of claim 1 , wherein the second composition comprises from 5% to 95%, by weight, of water, as the carrier.

10. The method of claim 1 , wherein the second composition is substantially free of a material selected from the group consisting of a propellant, ethanol, a detersive surfactant, and combinations thereof.

11. The method of claim 1 , wherein the second composition further comprises a suspending agent.

12. The method of claim 1 , wherein the second composition further comprises from about 0.01% to about 15%, by weight of the second composition, of a cross-linked polyacrylate polymer.
