The basic chemical reaction of making soap is the interaction between oil and alkali to generate soap and glycerin. The specific process is as follows:

  1. Refining: remove impurities in oil;
  2. Saponification: saponification reaction with alkali after oil refining;
  3. Salting out: salting out the soap obtained from the reaction, that is, adding salt or saturated salt water to the closed soap material to separate the soap from the dilute glycerin water;
  4. Washing: After separating the waste liquid, add water and steam to boil the soap grains to make them become uniform soap gel from the separated state, and wash out the residual glycerin, pigment and impurities;
  5. Alkali analysis: In order to fully saponify the remaining oil in the soap grains, the glycerin, salt, pigment and impurities in the soap grains are further washed out through alkali analysis;
  6. Finishing: add proper amount of electrolyte, adjust enough to separate the soap material into upper and lower soap phases. The upper layer is pure soap base, and the lower layer is soap foot;
  7. Forming: The soap base is condensed into a large soap board, and then cut into a soap blank, which is printed and dried into laundry soap, scented soap and other products. Huatai company supply palm oil processing, palm oil soap making, any need please email to [email protected]
