Homemade Castile Soap is Organic soap made from Olive oil.

Unlike most soaps, castile soap is made from Olive oil rather than "tallow" (a nice way to say "animal fat"). That means castile's soap's non-traditional base makes it cruelty-free and completely biodegradable with a extremely low carbon footprint.

The product originated in Spain's Castile region (hence the name!), and olive oil was the traditional base fat for this gentle, environmentally-responsible soap. But nowadays, it's made from a variety of vegetable-derived oils including coconut, avocado, walnut, almond, hemp, and more.
