Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
69 words
A toilet soap bar consisting essentially of sodium soap of higher fatty acids having about 10 to 20 carbon atoms as substantially the sole detergent, about 6 to 12 wt.% of superfatting higher fatty acids having about 10 to 20 carbon atoms, about 1 to 4 wt.% of poly(ethylenoxide) having a molecular weight in the range of about 100,000 to 5,000,000 and about 5 to 18 wt.% of water.
Claim 2
Dependent Claim
69 words
A toilet soap bar consisting essentially of sodium soap of higher fatty acids having about 10 to 20 carbon atoms as substantially the sole detergent, about 6 to 12 wt.% of superfatting higher fatty acids having about 10 to 20 carbon atoms, about 1 to 4 wt.% of poly(ethylenoxide) having a molecular weight in the range of about 100,000 to 5,000,000 and about 5 to 18 wt.% of water.
Claim 3
Dependent Claim
53 words
A toilet soap bar as in claim 1, in which said sodium soap is a mixture of tallow and coconut oil soaps in a weight ratio of about 1:2 to 2:1 and said superfatting acids comprise a mixture of stearic and coco fatty acids in a weight ratio of about 2:1 to 1:2.
Claim 4
Dependent Claim
30 words
A toilet soap bar as in claim 1 in which said molecular weight is about 300,000 to 600,000 and the proportion of poly(ethylene oxide) is about 11/2 to 3 wt.%.
Claim 5
Dependent Claim
31 words
A toilet soap bar as in claim 3 in which said sodium soap is a mixture of tallow and coconut oil soaps in a weight ratio of about 1:2 to 2:1.
Claim 6
Dependent Claim
35 words
A toilet soap bar as in claim 3 in which said sodium soap is a mixture of about equal parts of tallow and coconut oil soaps and constitutes about 3/4 of said bar, by weight.
Claim 7
Dependent Claim
30 words
A toilet soap bar as in claim 3 which said superfatting acids comprise a mixture of stearic and coco fatty acids in a weight ratio of ratio 2:1 to 1:2.
Claim 8
Dependent Claim
26 words
A toilet soap bar as in claim 3 in which said superfatting acids comprise a mixture of about equal parts of stearic and coco fatty acids.
Claim 9
Dependent Claim
53 words
A toilet soap bar as in claim 3 in which said sodium soap is a mixture of tallow and coconut oil soaps in a weight ration of about 1:2 to 2:1 and said superfatting acids comprise a mixture of stearic and coco fatty acids in a weight ratio of about 2:1 to 1:2.
