Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
126 words
Process for preparing toilet soap bars containing, approximately by weight, at least 60% of soap and between 0.5 and 10% of poly (ethylene oxide) having an average molecular weight of at least about 100,000 which comprises forming a first mixture of said soap in the form of chips and said poly(ethylene oxide) in the form of powder, said first mixture containing at least about 11% of moisture by weight of said chips whereby the surfaces of said soap chips are in powder-adherent condition with respect to said poly (ethylene oxide) powder, to produce soap chips having poly (ethylene oxide) bonded thereto, then mixing other conventional soap bar ingredients with said bonded chips to form a second mixture, then forming said second mixture into a soap bar.
Claim 2
Dependent Claim
126 words
Process for preparing toilet soap bars containing, approximately by weight, at least 60% of soap and between 0.5 and 10% of poly (ethylene oxide) having an average molecular weight of at least about 100,000 which comprises forming a first mixture of said soap in the form of chips and said poly(ethylene oxide) in the form of powder, said first mixture containing at least about 11% of moisture by weight of said chips whereby the surfaces of said soap chips are in powder-adherent condition with respect to said poly (ethylene oxide) powder, to produce soap chips having poly (ethylene oxide) bonded thereto, then mixing other conventional soap bar ingredients with said bonded chips to form a second mixture, then forming said second mixture into a soap bar.
Claim 3
Dependent Claim
23 words
Process as in claim 1 wherein said other ingredients contain only about 0.5 to 5% of synthetic surfactant by weight of the bar.
Claim 4
Dependent Claim
20 words
Process as in claim 1 wherein the moisture content of the soap chips is at least about 11% by weight.
Claim 5
Dependent Claim
34 words
Process as in claim 1 wherein the moisture content of the soap chips is less than about 11% by weight and sufficient water is added to said first mixture to provide said powder-adherent condition.
Claim 6
Dependent Claim
31 words
Process as in claim 1 wherein the other ingredients are selected from the group consisting of hydrolyzed protein, superfatting agent and a synthetic surfactant of high foaming characteristics and mixtures thereof.
Claim 7
Dependent Claim
11 words
A toilet soap bar produced by the process of claim 1.
Claim 8
Dependent Claim
42 words
A toilet soap bar containing by weight, about 0.5 to 10% of poly (ethylene oxide) having a molecular weight of at least 100,000 and at least 60% of soap, said bar being substantially free of visible specks caused by said poly(ethylene oxide).
Claim 9
Dependent Claim
42 words
A toilet soap bar containing by weight, about 0.5 to 10% of poly (ethylene oxide) having a molecular weight of at least 100,000 and at least 60% of soap, said bar being substantially free of visible specks caused by said poly(ethylene oxide).
Claim 10
Dependent Claim
21 words
A soap bar as in claim 7 wherein the poly(ethylene oxide) has a molecular weight of about 300,000 to about 400,000.
Claim 11
Dependent Claim
19 words
A soap bar as in claim 7 further containing about 0.1 to about 10% by weight of hydrolyzed protein.
Claim 12
Dependent Claim
21 words
A soap bar as in claim 9 wherein the hydrolyzed protein has a molecular weight of about 600 to about 12,000.
Claim 13
Dependent Claim
21 words
A soap bar as in claim 9 wherein the hydrolyzed protein has a molecular weight of about 1,000 to about 3,000
Claim 14
Dependent Claim
16 words
A soap bar as in claim 9 wherein the hydrolyzed protein is a collagen hydrolysis product.
Claim 15
Dependent Claim
27 words
A soap bar as in claim 9 containing about 1 to about 4% of the poly(ethylene oxide) and about 1 to about 5% of the hydrolyzed protein.
Claim 16
Dependent Claim
21 words
A soap bar as in claim 13 wherein the hydrolyzed protein provides a hydroxyproline content of about 0.1 to about 0.5%.
Claim 17
Dependent Claim
19 words
A soap bar as in claim 9 further containing a superfatting agent in an amount up to about 10%.
Claim 18
Dependent Claim
52 words
A soap bar as in claim 9 wherein the poly(ethylene oxide) has a molecular weight of about 300,000 to about 400,000 and further containing about 1 to about 5% of acetylated lanolin as superfatting agent, about 0.2 to about 1% of glycerine, and about 1 to about 3% of sodium coco isethionate.
Claim 19
Dependent Claim
21 words
A soap bar as in claim 11 wherein the poly(ethylene oxide) has a molecular weight of about 300,000 to about 400,000.
