Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
146 words
An article of manufacture adapted to be added to an automatic dryer, comprising: a. a fabric conditioning composition comprising a substantially homogeneous mixture of: i. a substantially water-insoluble fabric crisping component selected from the group consisting of alcohols, carboxylic acids, carboxylic acid salts, and mixtures thereof, said crisping component having a melting point of at least about 38° C; and ii. an oil-soluble surfactant component selected from the group consisting of nonionic ethoxylated alcohols and nonionic ethoxylated alkyl phenols having an HLB of from about 7 to about 9; wherein said crisping component is co-present with said surfactant component at a weight ratio of from about 1000:1 to about 1:1; and b. a dispensing means for releasing an effective amount of said fabric conditioning composition at automatic dryer operating temperatures, said dispensing means being a sponge, cloth or paper bag, or woven or nonwoven fabric substrate.
Claim 2
Dependent Claim
146 words
An article of manufacture adapted to be added to an automatic dryer, comprising: a. a fabric conditioning composition comprising a substantially homogeneous mixture of: i. a substantially water-insoluble fabric crisping component selected from the group consisting of alcohols, carboxylic acids, carboxylic acid salts, and mixtures thereof, said crisping component having a melting point of at least about 38° C; and ii. an oil-soluble surfactant component selected from the group consisting of nonionic ethoxylated alcohols and nonionic ethoxylated alkyl phenols having an HLB of from about 7 to about 9; wherein said crisping component is co-present with said surfactant component at a weight ratio of from about 1000:1 to about 1:1; and b. a dispensing means for releasing an effective amount of said fabric conditioning composition at automatic dryer operating temperatures, said dispensing means being a sponge, cloth or paper bag, or woven or nonwoven fabric substrate.
Claim 3
Dependent Claim
40 words
An article according to claim 1 wherein the crisping component is selected from the group consisting of cetyl alcohol, stearyl alcohol, tallowalkyl alcohol, glycerol-1,2-dilaurate, glycerol-1,3-dilaurate, glycerol-1,2-dimyristate, glycerol-1,3-dimyristate, glycerol-1,2-dipalmitate, glycerol-1,3-dipalmitate, glycerol-1,2-distearate, glycerol-1,3-distearate, 1,2-ditallowalkyl glycerol, 1,3-ditallowalkyl glycerol, 1,2-ditallowalkyl glycerol, and mixtures thereof.
Claim 4
Dependent Claim
18 words
An article according to claim 1 wherein the fabric conditioning composition is releasably contained within the dispensing means.
Claim 5
Dependent Claim
25 words
An article according to claim 1 wherein the dispensing means comprises a woven, non-woven or paper substrate having the fabric conditioning composition releasably affixed thereto.
Claim 6
Dependent Claim
15 words
An article according to claim 1 releasably containing an effective amount of an anti-static agent.
Claim 7
Dependent Claim
21 words
An article according to claim 1 wherein from about 10% about 25% by weight of the crisping component comprises paraffin wax.
Claim 8
Dependent Claim
31 words
An article according to claim 1 wherein from about 10% to about 60% by weight of the crisping component comprises a waxy ester having a melting point above about 38° C.
