97% Natural. Sandalwood hook up in this soap. Soft and sensual. We would love to use sandalwood essential oil but as the tree that sandalwood essentials is made from is diminishing, the price is driven over $130 an ounce (and an ounce of essentials goes into our smallest batches). There are many adulterated non pure sandalwood oils so in the best interest of our customers we choose fragrance for this soap.
