Abstract

Consumer products that include treatment adjuncts and delivery particles having certain sizes, certain monomers (for example, multifunctional (meth)acrylate monomers), and certain core:wall polymer weight ratios. Methods related to the use and manufacture of such compositions, including methods of treating a surface, such as a fabric.

First claim

What is claimed is:

1 . A consumer product composition comprising:
a treatment adjunct, and a population of delivery particles,
wherein the delivery particles comprise a core and a polymer wall surrounding the core,
wherein the core comprises a benefit agent and a partitioning modifier,
wherein the partitioning modifier is present in the core at a level of from about 25% to about 50%, by weight of the core,

wherein the partitioning modifier comprises isopropyl myristate, wherein the benefit agent comprises a fragrance,
wherein the polymer wall comprises a (meth)acrylate polymer derived, at least in part, from one or more oil-soluble or oil-dispersible multifunctional (meth)acrylate monomers or oligomers,
the one or more oil-soluble or oil-dispersible multifunctional (meth)acrylate monomers or oligomers having four to six radical polymerizable functional groups,
with the proviso that at least one of the radical polymerizable groups is acrylate or methacrylate;

wherein the core and the polymer wall are present in a weight ratio of from about 98.2 to about 99:1; and
wherein the delivery particles are characterized by a volume-weighted median particle size from about 30 to about 40 microns.

2 . The consumer product composition according to claim 1 , wherein the radical polymerizable functional groups are each independently selected from the group consisting of acrylate and methacrylate.

3 . The consumer product composition according to claim 1 , wherein the oil-soluble or oil-dispersible multifunctional (meth)acrylate monomers or oligomers comprise a multifunctional aromatic urethane acrylate.

4 . The consumer product composition according to claim 1 , wherein the oil-soluble or oil-dispersible multifunctional (meth)acrylate monomers or oligomers comprise a hexafunctional aromatic urethane acrylate.

5 . The consumer product composition according to claim 1 , wherein the oil-soluble or oil-dispersible multifunctional (meth)acrylate monomers or oligomers comprise a multifunctional aliphatic urethane acrylate.

6 . The consumer product composition according to claim 1 , wherein the (meth)acrylate polymer is further derived from, at least in part, a monomer selected from an amine methacrylate, an acidic methacrylate, or a combination thereof.

7 . The consumer product composition according to claim 1 , wherein the (meth)acrylate polymer of the polymer wall is a reaction product derived from the oil-soluble or oil-dispersible multifunctional (meth)acrylate, a second monomer, and a third monomer.

8 . The consumer product composition according to claim 1 , wherein the (meth)acrylate polymer of the polymer wall is further derived from a water-soluble or water-dispersible mono- or multifunctional (meth)acrylate monomer or oligomer.

9 . The consumer product composition according to claim 1 , wherein the polymer wall of the delivery particles further comprise a polymeric emulsifier entrapped in the polymer wall.

10 . The consumer product composition according to claim 1 , wherein the (meth)acrylate polymer of the polymer wall is further derived, at least in part, from at least one free radical initiator.

11 . The consumer product composition according to claim 10 , wherein the free radical initiator is present in amount of from about 5% to about 40%, by weight of the polymer wall.

12 . The consumer product composition according to claim 1 , wherein the benefit agent is a fragrance.

13 . The consumer product composition according to claim 1 , wherein the partitioning modifier is isopropyl myristate.

14 . The consumer product composition according to claim 1 , wherein the partitioning modifier further comprises vegetable oil, modified vegetable oil, mono-, di-, and tri-esters of C4-C24 fatty acids, dodecanophenone, lauryl laurate, methyl behenate, methyl laurate, methyl palmitate, methyl stearate, or mixtures thereof.

15 . The consumer product composition according to claim 1 , wherein the population of delivery particles are characterized by an average Fracture Strength of from about 0.2 to about 10 MPa.

16 . The consumer product composition according to claim 1 , wherein the polymer wall of the delivery particles further comprises a coating material.

17 . The consumer product composition according to claim 1 , wherein the composition comprises from about 0.05% to about 20%, by weight of the composition, of the delivery particles.

18 . The consumer product composition according to claim 1 , wherein the treatment adjunct is selected from the group consisting of surfactants, conditioning actives, deposition aids, rheology modifiers or structurants, bleach systems, stabilizers, builders, chelating agents, dye transfer inhibiting agents, dispersants, enzymes, enzyme stabilizers, catalytic metal complexes, polymeric dispersing agents, clay and soil removal/anti-redeposition agents, brighteners, suds suppressors, silicones, hueing agents, aesthetic dyes, neat perfume, additional perfume delivery systems, structure elasticizing agents, carriers, hydrotropes, processing aids, anti-agglomeration agents, coatings, formaldehyde scavengers, pigments, and mixtures thereof.

19 . The consumer product composition according to claim 1 , wherein the composition is a fabric care composition, a hard surface cleaner composition, a dish care composition, a hair care composition, a body cleansing composition, or a mixture thereof.

20 . The consumer product composition according to claim 1 , wherein the composition is in the form of a liquid composition, a granular composition, a hydrocolloid, a single-compartment pouch, a multi-compartment pouch, a dissolvable sheet, a pastille or bead, a fibrous article, a tablet, a stick, a bar, a flake, a foam/mousse, a non-woven sheet, or a mixture thereof.

21 . A method of treating a surface, wherein the method comprises the step of contacting the surface with a consumer product composition according to claim 1 , optionally in the presence of water.
