How do you make soap?

Answer 1

First some NaOH is added to saturated or unsaturated vegetable oils. We heat and stir them together slowly and a thick viscous whitish solution is formed which contains soap. It is then treated with common salt to cause precipitation .The soap floats over the salt solution . It is then scooped out and washed with water to remove excess NaOH and salt. At the end fillers are added to bring in certain properties for specific uses of the soap.
