Abstract

Microfibrillated cellulose, derived from vegetables or wood, can be used to provide a liquid composition which is compatible with a broad range of ingredients suitable for consumer applications, including enzymes, while still providing good structuring of the liquid composition, without affecting ease of pour.

First claim

What is claimed is:

1. A liquid composition comprising:
a) surfactant,
b) microfibrillated cellulose derived from sugar beet; and
c) enzymes selected from the group consisting of: cellulases, endoglucanase with activity towards xyloglucan, and mixtures thereof.

2. The composition according to claim 1 , wherein the surfactant is selected from the group consisting of: anionic surfactant, nonionic surfactant, cationic surfactant, and mixtures thereof.

3. The composition according to claim 1 , wherein the composition comprises from about 0.5% to about 40 wt % of the surfactant.

4. The composition according to claim 1 , wherein the microfibrillated cellulose has an aspect ratio (lid) of from about 50 to about 200,000.

5. The composition according to claim 1 , wherein the microfibrillated cellulose is derived from sugar beet and comprises less than about 10% soluble fibre as a percentage of total fibre.

6. The composition according to claim 1 , wherein the composition comprises from about 0.05 to about 10 wt % of the microfibrillated cellulose.

7. The composition according to claim 1 , wherein the composition comprises sufficient microfibrillated cellulose to provide a yield stress of greater than about 0.005 Pa.

8. The composition according to claim 1 , wherein the composition further comprises a suspended insoluble material.

9. A liquid composition comprising:
a) surfactant, and
b) microfibrillated cellulose derived from sugar beet,
wherein the composition further comprises a water-soluble polymer.

10. The composition according to claim 9 , wherein the water-soluble polymer is selected from carboxylate polymers, polyethylene glycol polymers, polyester soil release polymers, amine polymers, cellulosic polymers, dye transfer inhibition polymers, dye lock polymers, hexamethylenediamine derivative polymers, and mixtures thereof.

11. A process to manufacture a liquid composition comprising a surfactant, enzymes, and microfibrillated cellulose, the process comprising the steps of:
a) providing a structuring premix comprising microfibrillated cellulose, wherein the microfibrillated cellulose is derived from sugar beet;
b) providing a liquid premix comprising the surfactant, wherein said liquid premix further comprises enzymes selected from the group consisting of: cellulases, endoglucanase with activity towards xyloglucan, and mixtures thereof; and
c) incorporating the structuring premix into the liquid premix using high shear mixing.

12. A process according to claim 11 , wherein the structuring premix comprises a surfactant.

13. A composition according to claim 10 , wherein the water-soluble polymer comprises a soil release polymer, wherein the soil release polymer comprises terephthalate polymers.

14. A composition according to claim 1 , wherein the composition comprises from 0.15 wt % to 2 wt % of the microfibrillated cellulose.

15. A composition according to claim 1 , wherein the composition further comprises an enzyme, wherein the enzyme comprises lipase.

16. A composition according to claim 8 , wherein the suspended insoluble material comprises microcapsules, wherein the microcapsules comprise a microcapsule core and a microcapsule wall that surrounds the microcapsule core.

17. A composition according to claim 16 , wherein the microcapsules are perfume microcapsules.
