Abstract

Cleaning compositions that include an insoluble cationically-modified cellulose and external structurant. Methods of making and using such cleaning compositions.

Claims

1. A liquid cleaning composition comprising:

a) insoluble cationically-modified cellulose particles selected from the group consisting of microcrystalline cellulose, microfibrillated cellulose, nanocrystalline cellulose, cellulose nanofibers obtained by electrospinning and subsequently crushing the nanofibers, and mixtures thereof, wherein the cellulose particles have an average size of from 0.05 to 200 μ

m;

b) an external structurant selected from the group consisting of di-benzylidene polyol acetal derivative, bacterial cellulose, coated bacterial cellulose, di-amide gellants, and mixtures thereof; and

c) from about 25% to about 90% by weight of the composition of water, wherein the weight ratio of modified cellulose particle to external structurant is from 1;

1 to 2;

1.

2. A liquid cleaning composition according to claim 1, wherein the cellulose particles comprise a cellulose substrate functionalized with a quaternary ammonium compound of formula (I):

3. A liquid cleaning composition according to claim 2, wherein the cellulose substrate used is in the form of cellulose nanofibers obtained from electrospinning.

4. A liquid cleaning composition according to claim 1, wherein the cellulose particles are characterized by an aspect ratio of from about 1 to about 100.

5. A liquid cleaning composition according to claim 1, wherein the composition comprises from about 0.1% to about 5%, by weight of the composition, of the cellulose particles.

6. A liquid cleaning composition according to claim 1, wherein the composition comprises from about 0.1% to about 10%, by weight of the composition, of the external structurant.

7. A cleaning composition according to claim 1, wherein the cleaning composition further comprises from about 1% to about 80%, by weight of the cleaning composition, of a surfactant system.

8. A cleaning composition according to claim 1, wherein the surfactant system comprises an anionic surfactant selected from the group consisting of alkyl sulfate, alkyl alkoxy sulfate, alkyl benzene sulfonate, paraffin sulfonate, and mixtures thereof.
