Abstract
A process for the preparation of soap and soap/synthetic detergent products from raw materials normally employed in the manufacture of such products including fatty acids, triglycerides and caustic or alkali by subjecting such raw materials to intensive countercurrent mixing whereby saponification takes place in a relatively short time to yield a product, preferably in granular or powder form, which requires no further drying for most uses. The resulting product can, if desired, be then subjected to plodding, extrusion and stamping to form soap in bar form. The starting material can also be a mixture of such raw materials where neutralization has proceeded to some degree, preferably the neat soap stage.
Claims7
A process for making soap granules from a mixture of a fatty acid source and caustic or alkali wherein neutralization of said fatty acid source has proceeded to some degree comprising the steps of introducing said mixture into an enclosed mixing vessel, causing said mixture in said vessel to rotate in a generally circular path while simultaneously bringing said mixture into contact with a rotating means mounted within said vessel, said means rapidly rotating in a direction counter to the initial direction of flow of said mixture in said vessel whereby saponification, if required, takes place and soap granules are formed having a moisture content of less than about 20% by weight.
