Soap-Making Manual / A Practical Handbook on the Raw Materials, Their Manipulation, Analysis and Control in the Modern Soap Plant.

A practical handbook explains the raw materials of soapmaking—fats, oils, alkalis, rosin and auxiliaries—and their preparation and treatment. It describes plant construction, equipment, and principal manufacturing methods, providing classified formulas and procedures for laundry, toilet, transparent, shaving, liquid, textile and medicinal soaps. The work details glycerine-recovery processes and fatty-acid distillation alongside sampling and analytical methods for oils, soaps and glycerine to control quality. Illustrations, tables and guidance on bleaching, rancidity prevention, hydrogenation and simple tests are included to help operators and small plants perform manufacture and routine analysis.
