Saponified Olive Oil

Olive oil adds a rich feel to the soap and helps create a very hard bar once fully cured.

High in Oleic acid, this oil will absorb into the skin and form a protective barrier against the elements. It also acts as a humectant, drawing moisture to the skin and is said to help aid skin cell regeneration.
