There are two main stages in the technological process of soap production. The first is the preparation of aqueous solutions of fatty acid salts of various concentrations from fats, fat substitutes and alkalis. This chemical process is called soap boiling.
Depending on a number of conditions: the quality of the feedstock, the type and soap varieties this stage may consist of:
a) one operation of saponification of triglycerides or neutralization of carboxylic acids (direct method of cooking soap);
b) of two operations: 1) the actual production of fatty acid salts and 2) treatment of the resulting solution (soap glue) with electrolytes. As a result of this treatment, soap is freed from many undesirable impurities, and when saponification of neutral fats also from glycerin (an indirect method of cooking soap).
The second stage of the technological process consists of mixing boiled soap with various additives and giving it a marketable appearance. Depending on the type of soap produced, giving it a marketable appearance may consist of various operations
