Abstract

A detergent composition and processes for making and using same. A detergent composition that includes cellulose fibers to improve the deposition and/or retention of encapsulated benefit agent onto fabrics.

Claims (24)

1. A detergent composition, comprising, based on the total detergent composition weight:

a) from about 1.0% to about 90% of a detersive surfactant;

b) from about 0.01% to about 5% of cellulose fibers wherein at least about 80% of said cellulose fibers have a hydrodynamic radius above about 5 microns, and

c) from about 0.05% to about 10% of encapsulated benefit agent.

2. The detergent composition according to claim 1 , wherein at least about 80% of said cellulose fibers have a hydrodynamic radius between about 5 and about 65 microns.

3. The detergent composition according to claim 1 , wherein at least about 80% of said cellulose fibers have a hydrodynamic radius between about 10 and about 55 microns.

4. The detergent composition according to claim 1 , comprising, based on the total detergent composition weight, from about 0.05 to about 2.5% of said cellulose fibers.

5. The detergent composition according to claim 1 , wherein the encapsulated benefit agent is selected from the group consisting of perfume composition, moisturizers, a heating agent, a cooling agent, an insect/moth repellent, germ/mold/mildew control agents, softening agents, hueing dyes, enzymes and combinations thereof.

6. The detergent composition according to claim 5 , wherein the encapsulated benefit agent is a perfume composition.

7. The detergent composition according to claim 5 , said encapsulated benefit agent is encapsulated in capsules wherein said capsules comprise a capsule wall, said capsule wall comprising wall material selected from the group consisting of melamine, polyacrylamide, silicones, silica, polystyrene, polyurea, polyurethanes, polyacrylate based materials, polyacrylate esters based materials, gelatin, styrene malic anhydride, polyamides, aromatic alcohols, polyvinyl alcohol, resorcinol-based materials, poly-isocyanate-based materials, acetals, starch, cellulose acetate phthalate, and mixtures thereof.

8. The detergent composition according to claim 5 , said encapsulated benefit agent is encapsulated in capsules wherein said capsules comprise a capsule wall, said capsule wall comprises one or more wall material comprising melamine, polyacrylate based material and combinations thereof.

9. The detergent composition according to claim 1 , comprising, based on the total detergent composition weight, from about 0.00001% to about 5% of a deposition aid in addition to said cellulose fibers.

10. The detergent composition according to claim 9 , wherein the deposition aid in addition to said cellulose fibers is selected from the group consisting of polyvinylformamide, partially hydroxylated polyvinylformamide, polyvinylamine, polyethylene imine, ethoxylated polyethylene imine, polyvinylalcohol, polyacrylates, and combinations thereof.

11. The detergent composition according to claim 1 , having a pH of from about 5 to about 12.

12. The detergent composition according to claim 1 , wherein the cellulose fibers are derived from wood or jute.

13. A process of making the detergent composition of claim 1 , comprising the steps of:

a) activating the cellulose fibers wherein at least above 80% of said cellulose fibers have a hydrodynamic radius above about 5 microns in solution using a homogeniser at a pressure of at least about 80 bars;

b) dispersing the cellulose fibers in a surfactant solution using shear to form a structured surfactant composition;

c) combining the structured surfactant composition with an encapsulated benefit agent.

14. The process according to claim 13 , wherein said cellulose fibers are added to the surfactant as a pre-mix in water.

15. A method of treating a textile comprising the steps of:

a) contacting the textile with the detergent composition according to claim 1 ;

b) rinsing the surface of the textile.

16. The method of treating a textile according to claim 15 , wherein the contacting step occur in the presence of water, where the water and the detergent composition form a wash liquor.
