When fats and oils are combined, that is, an acid with a base, such as sodium or potassium hydroxide solution (depending on whether we want solid or liquid soap) then an exothermic chemical reaction occurs where soap and glycerol are produced.
The soap was created by the Sumerians from an accidental event when around 2,500 BC. fat fell on wood ash. Even today, soap can traditionally be made by boiling ashes (grease) with fats and oils, since the ash from the wood contains caustic potassium (KOH).
This process is called saponification, and in the cold saponification process heat is not required until the fats and oils that will be saponified are in liquid form. The cold method is most appropriate as it does not burden the environment with waste and energy waste to heat and boil the materials as in the hot saponification method but also because the precious glycerin produced is incorporated and remains in the soap enhancing its moisturizing properties
For all these reasons, Rania K soaps are produced by the cold saponification method, with pure natural materials, knowledge and taste, for our family and for you, our friends …
Because we all deserve the best, especially when it comes to taking care of our bodies and our health.
