Abstract
Abstract Solid soap such as framed or milled toilet soap, which is conventional in all aspects except that it contains as part of its composition 5 to 100 percent, based upon the weight of free fatty acid components, of at least one "bath oil." The solid soap composition is produced by first saponifying an appropriate fatty acid or mixture thereof in the usual way, solidifying the saponified material by cooling, extruding ribbons of solidified material, drying the extrudate, and then framing the dried extrudate into soap bars. The process hereof differs from this "usual" process in that bath oil, in whatever quantity is desired, is added to the liquid saponification mixture, rather than just prior to the framing step as in the prior art.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
181 words
In the process of producing solid, milled bar soap comprising: A. heating a mixture of soap making ingredients comprising soap producing fatty acids, fatty acid glycerides or mixtures thereof and a saponifying proportion of alkali to an elevated saponifying temperature sufficient to form a hot liquid mixture of soap and water; B. cooling said hot liquid mixture thereby solidfying such; C. drying said mixture; and then D. forming said dried solid mixture into solid bar soap by a process comprising milling, plodding and extruding; the improvement, whereby producing solid, milled bar soap containing about 5 to 100 weight percent, based upon the fatty acid content of said soap, of mineral oil, which comprises: adding to said hot liquid mixture of soap and water produced by step A a substantially water insoluble additive comprising mineral oil whereby forming a homogeneous, hot liquid mixture comprising said soap, water and about 5 to 100 weight precent, based upon the fatty acid content of said soap, of said mineral oil; and subjecting said homogeneous, hot liquid mixture to steps B, C and D as aforesaid.
Claim 2
Dependent Claim
181 words
In the process of producing solid, milled bar soap comprising: A. heating a mixture of soap making ingredients comprising soap producing fatty acids, fatty acid glycerides or mixtures thereof and a saponifying proportion of alkali to an elevated saponifying temperature sufficient to form a hot liquid mixture of soap and water; B. cooling said hot liquid mixture thereby solidfying such; C. drying said mixture; and then D. forming said dried solid mixture into solid bar soap by a process comprising milling, plodding and extruding; the improvement, whereby producing solid, milled bar soap containing about 5 to 100 weight percent, based upon the fatty acid content of said soap, of mineral oil, which comprises: adding to said hot liquid mixture of soap and water produced by step A a substantially water insoluble additive comprising mineral oil whereby forming a homogeneous, hot liquid mixture comprising said soap, water and about 5 to 100 weight precent, based upon the fatty acid content of said soap, of said mineral oil; and subjecting said homogeneous, hot liquid mixture to steps B, C and D as aforesaid.
Claim 3
Dependent Claim
17 words
The process claimed in claim 1 wherein said additive is an emollient mixture containing said mineral oil.
Claim 4
Dependent Claim
31 words
The process claimed in claim 1 wherein said mineral oil is present in a proportion of about 5 to 50 weight percent based on the fatty acid content of said soap.
Claim 5
Dependent Claim
14 words
the process claimed in claim 2 wherein said emollient consists essentially of mineral oil.
Claim 6
Dependent Claim
36 words
The process claimed in claim 1 wherein the heating of step A is to about 190° to 200° F and the mixture is dried to a moisture content of 5 to 12 percent in step C.
Claim 7
Dependent Claim
14 words
A substantially homogeneous solid milled bar soap produced by the process of claim 1.
