Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 217 words
A process for making an aerated freezer soap bar comprising the steps of: I. Mixing a soap bar composition comprising: (A) from about 25 wt. % to about 70 wt. % of alkali metal fatty acid soap in which said fatty acids contain from about 8 to about 18 carbon atoms; (B) from about 5 wt. % to about 35 wt. % of sucrose; (C) from about 3 wt. % to about 20 wt. % of a hydrophobic material selected from waxes, free fatty acids and fatty alcohols containing from about 8 to about 18 carbon atoms and wherein said composition contains at least about 3 wt. % of said wax; and (D) from about 10 wt. % to about 30 wt. % water; wherein said composition does not contain an effective amount of water-soluble organic non-soap synthetic detergent; at a temperature of from about 82° C. to about 100° C. (from about 180° F. to about 212° F.); said mix being fluid, substantially homogeneous, and pumpable; II. Aerating said mix; III. Cooling said mix to a temperature of from about 49° C. to about 66° C. (from about 120° F. to about 160° F.); and IV. Forming aerated bars from said aerated and cooled mix, wherein said process does not include a moisture reduction drying step.
Claim 2
Dependent Claim 217 words
A process for making an aerated freezer soap bar comprising the steps of: I. Mixing a soap bar composition comprising: (A) from about 25 wt. % to about 70 wt. % of alkali metal fatty acid soap in which said fatty acids contain from about 8 to about 18 carbon atoms; (B) from about 5 wt. % to about 35 wt. % of sucrose; (C) from about 3 wt. % to about 20 wt. % of a hydrophobic material selected from waxes, free fatty acids and fatty alcohols containing from about 8 to about 18 carbon atoms and wherein said composition contains at least about 3 wt. % of said wax; and (D) from about 10 wt. % to about 30 wt. % water; wherein said composition does not contain an effective amount of water-soluble organic non-soap synthetic detergent; at a temperature of from about 82° C. to about 100° C. (from about 180° F. to about 212° F.); said mix being fluid, substantially homogeneous, and pumpable; II. Aerating said mix; III. Cooling said mix to a temperature of from about 49° C. to about 66° C. (from about 120° F. to about 160° F.); and IV. Forming aerated bars from said aerated and cooled mix, wherein said process does not include a moisture reduction drying step.
Claim 3
Dependent Claim 43 words
The process of claim 1 wherein said aerated and cooled bars are free standing and wherein said temperature of Step I. is from about 85° C. to about 95° C. and said cooling temperature is from about 50° C. to about 60° C.
Claim 4
Dependent Claim 32 words
The process of claim 1 wherein said process is continuous and said water content of said mix and said aerated bars is from about 20 wt. % to about 25 wt. %.
Claim 5
Dependent Claim 159 words
A process for making a non-aerated soap bar from the composition of comprising: (A) from about 25 wt. % to about 70 wt. % of alkali metal fatty acid soap in which said fatty acids contain from about 8 to about 18 carbon atoms; (B) from about 5 wt. % to about 35 wt. % of a nonreducing sugar; (C) from about 3 wt. % to about 30 wt. % of hydrophobic material selected from the group consisting of waxes; free fatty acids containing from about 0 to about 10 carbon atoms; mono-, di-, and triglycerides; fatty alcohols containing from about 8 to about 18 carbon atoms and wherein said composition contains at least about 3 wt. % of said wax; and mixtures thereof; and (D) from about 15 wt. % to about 25 wt. % water; wherein said composition does not contain an effective amount of water-soluble organic non-soap synthetic detergent; wherein said process comprises the steps of:
Claim 6
Dependent Claim 159 words
A process for making a non-aerated soap bar from the composition of comprising: (A) from about 25 wt. % to about 70 wt. % of alkali metal fatty acid soap in which said fatty acids contain from about 8 to about 18 carbon atoms; (B) from about 5 wt. % to about 35 wt. % of a nonreducing sugar; (C) from about 3 wt. % to about 30 wt. % of hydrophobic material selected from the group consisting of waxes; free fatty acids containing from about 0 to about 10 carbon atoms; mono-, di-, and triglycerides; fatty alcohols containing from about 8 to about 18 carbon atoms and wherein said composition contains at least about 3 wt. % of said wax; and mixtures thereof; and (D) from about 15 wt. % to about 25 wt. % water; wherein said composition does not contain an effective amount of water-soluble organic non-soap synthetic detergent; wherein said process comprises the steps of:
Claim 7
Dependent Claim 71 words
Mixing said (A), (B), (C), and (D) at a temperature of from about 82° C. to about 102° C. (180° F. to about 215° F.); 2. Cooling said mix of Step I. to a temperature of from about 49° C. to about 60° C. (120° F. to about 160° F.); and 3. Forming said non-aerated bars from said cooled mix, wherein said process does not include a moisture reduction drying step.
Claim 8
Dependent Claim 71 words
Mixing said (A), (B), (C), and (D) at a temperature of from about 82° C. to about 102° C. (180° F. to about 215° F.); 2. Cooling said mix of Step I. to a temperature of from about 49° C. to about 60° C. (120° F. to about 160° F.); and 3. Forming said non-aerated bars from said cooled mix, wherein said process does not include a moisture reduction drying step.
Claim 9
Dependent Claim 10 words
The process of claim 4 wherein said process is continuous.
