Abstract
Abstract A soap composition which when admixed with water forms a liquid aqueous soap solution that will not solidify or gel upon cooling. The preferred composition comprises a minor amount of a blend from about 50 to 95 percent by weight of a dry neutral alkali metal soap of a fatty acid of a minimum titre of 42°C. and a major amount of water. A preferred fatty acid is stearic acid which acts upon the concentrated soap solution to prevent gellation of the same upon cooling.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
143 words
A dilute aqueous liquid non-gelling soap composition which consists of: a. a major amount of water by weight and, b. a minor amount of less than 10% by weight of a powder dissolved therein having a titre of from 40° - 44°C said powder consisting of: 1. From at least 50 to about 95% by weight of a dry neutral alkali metal soap of a fatty acid or mixture of fatty acids having a titre of from about 36° - 42°C and, 2. from about 5 - 50% of a free fatty acid of a titre of at least 42°C having from about C 12 to C 22 Carbon atoms in the fatty acids therein, sufficient to prevent gellation and wherein the fatty acid component of the composition acts as a stabilizer for the composition when the same is further dissolved in water.
Claim 2
Dependent Claim
143 words
A dilute aqueous liquid non-gelling soap composition which consists of: a. a major amount of water by weight and, b. a minor amount of less than 10% by weight of a powder dissolved therein having a titre of from 40° - 44°C said powder consisting of: 1. From at least 50 to about 95% by weight of a dry neutral alkali metal soap of a fatty acid or mixture of fatty acids having a titre of from about 36° - 42°C and, 2. from about 5 - 50% of a free fatty acid of a titre of at least 42°C having from about C 12 to C 22 Carbon atoms in the fatty acids therein, sufficient to prevent gellation and wherein the fatty acid component of the composition acts as a stabilizer for the composition when the same is further dissolved in water.
Claim 3
Dependent Claim
24 words
A composition according to claim 1 herein the fatty acid component is substantially stearic acid having a titre which ranges from 42° to 48°C.
Claim 4
Dependent Claim
35 words
A composition according to claim 1 wherein the fatty acid component (2) is stearic acid having a titre of 52° to 60°C present as a mechanical mixture with the neutral alkali metal soap component (1).
Claim 5
Dependent Claim
57 words
A composition according to claim 1 wherein the neutral alkali metal soap and the saturated free fatty acid component are intimately comingled in a molten state wherein the fatty acid component added into the melt has a titre which ranges from 42° - 48°C and the final titre of the comixed melt is about 40° - 44°C.
