Claim 1
Independent Claim
107 words
An article of manufacture especially adapted for conditioning fabrics, comprising: a. an effective amount of a clay mixture 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 clay of from about 20:1 to about 1:20; said clay mixture being in releasable combination with; b. a water-insoluble dispensing means.
Claim 2
Dependent Claim
107 words
An article of manufacture especially adapted for conditioning fabrics, comprising: a. an effective amount of a clay mixture 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 clay of from about 20:1 to about 1:20; said clay mixture being in releasable combination with; b. a water-insoluble dispensing means.
Claim 3
Dependent Claim
31 words
An article 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
An article according to claim 1 wherein the clay mixture 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
27 words
An article according to claim 1 wherein the clay mixture is in the form of an aqueous gel and wherein the dispensing means is a perforated pouch.
Claim 6
Dependent Claim
