Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
113 words
A clay-based fabric conditioning composition comprising clay mixtures selected from: mixtures of hydrophilic Laponite clay and hydrophobic Laponite clay, at a weight ratio of hydrophilic Laponite to hydrophobic Laponite of from about 20:1 to about 1:20; mixtures of hydrophilic Laponite clay and smectite clay, at a weight ratio of hydrophilic Laponite to smectite of from about 20:1 to about 1:20; and mixtures of hydrophobic Laponite clay and smectite clay, at a weight ratio of hydrophobic Laponite to smectite clay of from about 20:1 to about 1:20, wherein the smectite clay in the admixture with the hydrophilic Laponite clay and hydrophobic Laponite clay has an ion exchange capacity of at least 50 meq/100 g.
Claim 2
Dependent Claim
113 words
A clay-based fabric conditioning composition comprising clay mixtures selected from: mixtures of hydrophilic Laponite clay and hydrophobic Laponite clay, at a weight ratio of hydrophilic Laponite to hydrophobic Laponite of from about 20:1 to about 1:20; mixtures of hydrophilic Laponite clay and smectite clay, at a weight ratio of hydrophilic Laponite to smectite of from about 20:1 to about 1:20; and mixtures of hydrophobic Laponite clay and smectite clay, at a weight ratio of hydrophobic Laponite to smectite clay of from about 20:1 to about 1:20, wherein the smectite clay in the admixture with the hydrophilic Laponite clay and hydrophobic Laponite clay has an ion exchange capacity of at least 50 meq/100 g.
Claim 3
Dependent Claim
30 words
A composition according to claim 1 wherein the clay mixture comprises hydrophilic Laponite clay and smectite clay at a weight ratio of hydrophilic Laponite:smectite from about 1:10 to about 1:1.
Claim 4
Dependent Claim
30 words
A composition according to claim 1 wherein the clay mixture comprises hydrophilic Laponite and hydrophobic Laponite at a weight ratio of hydrophilic Laponite:hydrophobic Laponite from about 1:10 to about 1:1.
Claim 5
Dependent Claim
14 words
A composition according to claim 1 comprising, as an additional component, a water-soluble carrier.
Claim 6
Dependent Claim
12 words
A composition according to claim 4 wherein the carrier is a liquid.
Claim 7
Dependent Claim
14 words
A composition according to claim 5 wherein the liquid is water or water-alcohol mixtures.
Claim 8
Dependent Claim
14 words
A composition according to claim 4 wherein the water-soluble carrier is a detergency builder.
Claim 9
Dependent Claim
19 words
A composition according to claim 1 comprising, as an additional component, an effective amount of an organic fabric conditioner.
Claim 10
Dependent Claim
23 words
A composition according to claim 8 wherein the organic fabric conditioner is a fatty-based material selected from quaternary ammonium salts and sorbitan esters.
Claim 11
Dependent Claim
31 words
A composition according to claim 1 wherein the particle size range of the hydrophilic Laponite clay, hydrophobic Laponite clay and smectite clay is from about 0.01 micron to about 50 microns.
