and Arthur Speier. The reaction is also sometimes known as Fischer-Speier Esterification. The major components of almost all natural flavors and odors are esters.

The absorbent charcoal draws out impurities and acts as a natural disinfectant - killing germs whilst removing dirt and dead skin cells from the surface of the skin. We use meadowfoam seed oil as a superfat (the oil is added at the end of the saponification process‚ therefore remaining intact in the finished soap). This amazing oil has many benefits :- it moisturises and nourishes the skin‚ it penetrates immediately and is non-greasy‚ it reduces wrinkles and signs of ageing. It has an incredible
