My bath bars are made with sustainable palm and coconut oil, olive oil, and castor oil. The coconut oil helps to create a nice hard soap that has a skin nourishing lather. Palm oil also helps to harden the bar, along with the four to six week drying process. Olive oil gives a rich feel to the soaps and helps to make a very hard bar once fully cured. Castor oil helps increase lather while attracting moisture to your skin.
