Olive Oil Soap & Coconut Oil Soap: Simple Oils, Clever Science
Now come closer, because this is where tradition shakes hands with chemistry.
Olive oil soap is not simply cooking oil poured into a mould and left overnight. Natural oils must undergo a process called saponification. During this process, carefully measured oils react with an alkali and are transformed into true soap. When the formula is properly calculated and the reaction is completed correctly, the alkali has done its job and no free lye remains in the finished bar.
Daddy respects traditional methods, but he does not replace the measuring scale with wishful thinking. Good natural soap requires knowledge, precision and patience.
Different oils also contribute different qualities to a bar.
Olive oil is traditionally valued in soapmaking for the smooth, creamy and gentle-feeling character it can bring to the lather. It helps create the comforting washing experience commonly associated with traditional olive oil soaps and Castile-style bars.
Coconut oil behaves differently. It can help produce a firmer coconut oil soap with a fuller, bubblier and more effective cleansing lather. But balance matters, darling. A formula overloaded with coconut oil may feel too cleansing for some dry or sensitive skin, which is why thoughtful soapmaking is about combining ingredients intelligently, not simply adding more because the ingredient sounds impressive.
Saponification also creates glycerin. In many traditionally produced natural soap bars, that glycerin remains within the finished soap and can contribute to a softer, more comfortable after-wash feel.
Simple ingredients, yes. Simple-minded formulation? Absolutely not.
