Summary A new continuous process for the manufacture of soap is described, detailing the three main operations in soapmaking, that is, saponification, washing, and fitting. In the new process all operations involved in the production of soap are carried out in a hermetically closed system. The amounts of lye necessary for the saponification as well as of brine for the washing and fitting operations are regulated by the automatic constant‐composition control system, which eliminates the older method of control of the soapmaking process by cumbersome chemical analyses. The process is based on the use of the Hermetic separator, a centrifuge of special design which allows the regulation of the separation efficiency during operation and which prevents any admixture or contact of the soap with air and consequently any oxidation of the product during processing. All type of soap, high grade toilet soap as well as laundry soap and industrial soaps, can be produced by this process, which is characterized by high flexibility, low operation‐costs, and a high quality of the finished product.
