Abstract
Abstract A process for making a translucent soap in which a blend of selected fatty acids is saponified with a special caustic solution for neutralizing these fatty acids, and there is added to the saponified material polyethylene glycol and propylene glycol as agents for promoting translucency. The soap, including these additives, is spray dried and subjected to finishing steps in which the soap is refined and formed into bars. A further improvement involves heating of the soap to a relatively high temperature before spray drying.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
32 words
A process as set forth in claim 1 wherein the fatty acids consist essentially of from 85 - 70 percent tallow fatty acids and from 15 - 30 percent coconut fatty acids.
Claim 2
Dependent Claim
26 words
A process as set forth in claim 1 wherein said soap containing said additives is heated to a temperature of at least 290*F. before spray drying.
Claim 3
Dependent Claim
54 words
A process as set forth in claim 1 wherein said fatty acid is saponified with an alkali consisting essentially of sodium hydroxide in a proportion of from 90 - 99 percent and potassium hydroxide in a proportion of from 1 - 10 percent, said percentages being based on the total weight of said alkali.
Claim 4
Dependent Claim
109 words
A process as set forth in claim 1 wherein said fatty acids consist essentially of from 85 - 70 percent tallow fatty acids and from 15 - 30 percent coconut fatty acids, said percentages being based on the total weight of the acids and wherein there is used in said saponification an alkali consisting essentially of sodium hydroxide in a proportion of from 90 - 99 percent and potassium hydroxide in a proportion of from 1 - 10 percent, said percentages being based on the total weight of said alkali, and wherein said soap containing said additives is heated to a temperature of at least 290*F. before spray drying.
Claim 5
Dependent Claim
64 words
A process as set forth in claim 1 which includes the step of adding to said soap after the drying step, a perfume composition in an amount up to 1.0 percent based on the total weight of the soap, said composition containing polyethylene glycol and propylene glycol each in an amount of from 0.3 - 0.9 percent based on the weight of said soap.
Claim 6
Dependent Claim
28 words
A process as set forth in claim 2 wherein said fatty acid consists essentially of about 80 percent tallow fatty acid and about 20 percent coconut fatty acid.
Claim 7
Dependent Claim
25 words
A process as set forth in claim 4 wherein said alkali consists essentially of about 95 percent sodium hydroxide and about 5 percent potassium hydroxide.
Claim 8
Dependent Claim
80 words
In a process for the production of translucent soap in which fatty acids are saponified, the resulting soaps spray dried, refined and formed into bars, the improvement in which there is added to said soap after the saponifying step and before the soap is subjected to spray drying, polyethylene glycol in an amount of from 1 - 3 percent, and glycerine in an amount of from 1 - 3 percent, said percentages being based on the weight of said soap.
Claim 9
Dependent Claim
80 words
In a process for the production of translucent soap in which fatty acids are saponified, the resulting soaps spray dried, refined and formed into bars, the improvement in which there is added to said soap after the saponifying step and before the soap is subjected to spray drying, propylene glycol in an amount of from 1 - 3 percent, and glycerine in an amount of from 1 - 3 percent, said percentages being based on the weight of said soap.
