Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
95 words
A liquid fabric care composition suitable for restoring body and softness to fabrics comprising: (a) from about 1% to about 25% of a gelatinized and stabilized vegetable starch prepared by exposing a water dispersion of a gelatinized vegetable starch to a pH of from about 10 to about 13 to stabilize said starch and thereafter neutralizing any excess alkali to provide a pH of from about 4 to about 9; (b) from about 0.25% to about 10% of a cationic quaternary ammonium antistatic and/or fabric softening agent; (c) from about 25% to about 98% water.
Claim 2
Dependent Claim
95 words
A liquid fabric care composition suitable for restoring body and softness to fabrics comprising: (a) from about 1% to about 25% of a gelatinized and stabilized vegetable starch prepared by exposing a water dispersion of a gelatinized vegetable starch to a pH of from about 10 to about 13 to stabilize said starch and thereafter neutralizing any excess alkali to provide a pH of from about 4 to about 9; (b) from about 0.25% to about 10% of a cationic quaternary ammonium antistatic and/or fabric softening agent; (c) from about 25% to about 98% water.
Claim 3
Dependent Claim
55 words
The composition of claim 1 wherein the starch is gelatinized by holding a water dispersion of said starch at a temperature above its gelatinization temperature for at least about 5 minutes and stabilized by exposing said dispersion to a pH of from about 10 to about 13 during at least part of the gelatinization procedure.
Claim 4
Dependent Claim
12 words
The composition of claim 1 wherein the vegetable starch is corn starch.
Claim 5
Dependent Claim
65 words
The composition of claim 2 wherein the cationic quaternary ammonium antistatic and/or fabric softening agent is selected from the group consisting of: (a) compounds having the structure ##STR2## wherein R 1 , R 2 , R 3 and R 4 are hydrocarbon or substituted hydrocarbon radicals of which at least one contains 10 or more carbon atoms; (b) alkyl imidazolinium compounds; and (c) mixtures thereof.
Claim 6
Dependent Claim
17 words
The composition of claim 4 wherein the cationic antistatic and/or fabric softening agent is ditallowalkyldimethyl ammonium chloride.
Claim 7
Dependent Claim
25 words
The composition of claims 1, 2, 3, 4 or 5 comprising from about 2.5% to about 10% by weight of gelatinized and stabilized vegetable starch.
Claim 8
Dependent Claim
42 words
The composition of claims 1, 2, 3, 4 or 5 comprising from about 2.5% to about 10% by weight of gelatinized and stabilized starch and from about 0.5% to about 3% by weight of cationic quaternary ammonium antistatic and/or fabric softening agent.
