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

1 . A liquid composition comprising:
a) surfactant, b) microfibrillated cellulose derived from wood, 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 (l/d) of from about 50 to about 200,000.

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

6 . (canceled)

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

8 . 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.

9 . (canceled)

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

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

12 . The composition according to claim 11 , 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.

13 . A process to manufacture a liquid composition comprising a surfactant and microfibrillated cellulose derived from wood, the process comprising the steps of:
a) providing a structuring premix comprising microfibrillated cellulose, wherein the microfibrillated cellulose is derived from wood; b) providing a liquid premix comprising the surfactant; and c) incorporating the structuring premix into the liquid premix using high shear mixing.

14 . A process according to claim 13 , wherein the structuring premix comprises a surfactant.

15 . The composition according to claim 1 , wherein the composition further comprises enzymes selected from the group consisting of: lipase, protease, amylase, mannanase, pectate lyase, xyloglucanase, and mixtures thereof.

16 . The composition according to claim 1 , wherein the composition further comprises enzymes selected from the group consisting of: lipase, protease, amylase, and mixtures thereof.

17 . The composition according to claim 10 , wherein the suspended insoluble material is selected from the group consisting of: particulates, insoluble fluids, and mixtures thereof.

18 . The composition according to claim 10 , wherein the suspended insoluble material comprises particulates.

19 . The composition according to claim 18 , wherein the particulates are microcapsules.

20 . The composition according to claim 19 , wherein the microcapsules are perfume encapsulates.

21 . The composition according to claim 20 , wherein the perfume encapsulates comprise formaldehyde-based resin.

22 . The composition according to claim 10 , wherein the suspended insoluble matter comprises silicone.
