Abstract

Hard soaps are made by saponifying fats, fatty oils or fatty acids at a temperature of 125-260 DEG C. and under a pressure of about 2-6 atmospheres, with the required amount of caustic soda and caustic potash. Tallow, coco-nut oil, or caproic, caprylic, capric, lauric, myristic, palmitic, or stearic acids or the corresponding glycerides may be used. Salts such as sodium or potassium chloride, carbonate, borate, sulphate or phosphate, or sodium silicate or borax may be included in the saponification mixture, to lower the solidification temperature of the resulting soap. Large amounts of these salts, especially sodium carbonate, may be incorporated in the soap together with colloidal clay by using pressures up to 10 atmospheres. After saponification additional soft fat or oil may be added to form a soap containing 60-70 per cent fatty acids, suitable for milling, or for making soap flakes or powder. Specifications 378,913 and 378,914 are referred to.
