Abstract

A consumer product including a fabric and home composition providing for multiple blooms of fragrance, the multiple blooms being provided for by different populations of microcapsules and method related thereto.

Claims (24)

1. A consumer product comprising a composition, the composition comprising:

an adjunct material;

a first population of microcapsules, the first population having a first median volume weighted particle size of from 2 microns to 80 microns and comprising microcapsules comprising a partitioning modifier and a first perfume oil at a first weight ratio, wherein the first weight ratio is a weight ratio of from 2:3 to 3:2 of the partitioning modifier to the first perfume oil; and

a second population of microcapsules, the second population having a second median volume weighted particle size of from 2 microns to 80 microns and comprising microcapsules comprising the partitioning modifier and a second perfume oil at a second weight ratio, wherein the second weight ratio is a weight ratio of greater than 0 to less than 2:3 of the partitioning modifier to the second perfume oil;

wherein the partitioning modifier is isopropyl myristate;

wherein the first median volume weighted particle size and the second median volume weighted particle size are different;

wherein the composition is a fabric and home care composition.

2. The consumer product of claim 1 , wherein the weight ratio of the first population of microcapsules to the second population of microcapsules exceeds 1:1.

3. The consumer product of claim 1 , wherein the first perfume oil and the second perfume oil are the same.

4. The consumer product of claim 1 , wherein the adjunct material comprises a non-encapsulated perfume oil.

5. The consumer product of claim 4 , wherein the non-encapsulated perfume oil is different from the first and second perfume oil.

6. The consumer product of claim 1 , wherein the microcapsules further comprise a shell 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, silk, wool, gelatine, cellulose, proteins, and mixtures thereof.

7. The consumer product of claim 1 , wherein the microcapsules further comprise a shell material comprising a reaction product of a first substance in the presence of a second substance comprising an emulsifier, the first substance comprising a reaction product of i) an oil soluble or dispersible amine with ii) a multifunctional acrylate or methacrylate monomer or oligomer, an oil soluble acid and an initiator, the emulsifier comprising a water soluble or water dispersible acrylic acid alkyl acid copolymer, an alkali or alkali salt, and optionally a water phase initiator.

8. The consumer product of claim 1 , wherein the adjunct material comprises at least one surfactant, the at least one surfactant comprising from about 0.01% to about 30% by weight of the composition.

9. The consumer product of claim 1 , wherein the adjunct material comprises a fabric softening active.

10. The consumer product of claim 1 , wherein the adjunct material comprises water.

11. The consumer product of claim 1 , wherein the adjunct material comprises a builder.

12. The consumer product of claim 1 , wherein the adjunct material comprises a material selected from the group consisting of dispersants, enzymes, dye transfer inhibiting agents, chelants, brighteners, stabilizers, silicones, fabric hueing agent, structurant, anti-agglomeration agent, and mixtures thereof.

13. The consumer product of claim 1 , wherein the adjunct material comprises a deposition aid.

14. The consumer product of claim 1 , wherein the consumer product is in the form of a single unit dose or a multi-compartment unit dose.

15. The consumer product of claim 14 , wherein the adjunct material comprises polyvinyl alcohol.

16. The consumer product of claim 1 , wherein the consumer product is selected from the group consisting of all-purpose washing agents; heavy-duty washing agents; liquid fine-fabric detergents; hand dishwashing agents; light duty dishwashing agents; machine dishwashing agents, liquid cleaning and disinfecting agents; fabric conditioning products; cleaning auxiliaries; substrate-laden products; sprays; and mists.

17. The consumer product of claim 1 , wherein the first perfume oil and the second perfume oil comprise at least one different material.

18. The consumer product of claim 1 , wherein the first population and the second population comprise different shell materials.
