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 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 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.
Claims18
A process for making soap granules from raw materials normally employed in soap manufacture including a fatty acid source and caustic comprising the steps of introducing said materials into an enclosed mixing vessel, causing said materials in said vessel to rotate in a generally circular path while simultaneously bringing said materials 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 materials in said vessel whereby saponification takes place and soap granules are formed having a moisture content of less than about 20% by weight.
A process for making soap in the form of granules from materials normally employed in soap manufacture including a fatty acid source and caustic comprising the steps of introducing said materials into an enclosed mixing vessel, causing said materials to be subjected to intensive countercurrent mixing for a period of time sufficient to form soap granules having a moisture content of less than about 20% by weight.
A process for making transparent soap from a fatty acid source, caustic, triethanolamine and glycerine comprising the steps of:
- introducing said caustic into an enclosed mixing vessel provided with a pan and a rotating means mounted within said pan and said vessel, each of said pan and said rotating means being rotatable in a direction counter to each other, starting the rotation of said pan, introducing said fatty acid source into said pan and starting the rotation of said rotating means to provide countercurrent mixing, introducing triethanolamine and glycerine into said pan and continuing said countercurrent mixing until saponification is complete, heating the resulting soap until liquid and thereafter pouring said liquid soap into a suitable mold.
A process for making transparent soap from materials normally employed in the manufacture of said soaps including a fatty acid source, caustic, triethanolamine and glycerin comprising the steps of introducing said materials into an enclosed mixing vessel, causing said materials to be subjected to intensive counter-current mixing for a period of time sufficient to complete saponification, heating the resulting soap until liquid and thereafter pouring said liquid into a suitable mold.
A process for making soap in granular form from raw materials normally employed in soap manufacture including a fatty acid source, and caustic comprising the steps of introducing said fatty acid source into an enclosed mixing vessel provided with a pan and a rotating means mounted within said pan and said vessel, each of said pan and said means being rotatable in a direction counter to each other, introducing said caustic into said pan when at least a portion of said fatty acid source is in said pan, starting the rotation of said pan and said means, beginning the blowing of air into said pan after saponification is essentially complete and continuing the rotation of said pan and means until soap graules having a moisture content of less than about 20% by weight are obtained.
