What is olive oil soap and how is it made?
Olive oil soap is a solid soap made by saponifying olive oil with an alkali. On the ingredient list, saponified olive oil appears as Sodium Olivate.
Soaps of this kind have a long tradition around the Mediterranean; in Spain and beyond, soap made mainly from olive oil is also known as Castile soap. Ingredient names such as Sodium Olivate can be checked in CosIng, the EU database of cosmetic ingredients.
